Japanese Patent Laid-Open No. 2002-356827

By the way, since the beach cleaner and the garbage collection station are transported in a state where they are loaded on a trailer to a predetermined work place, it is desirable that the relatively large garbage collection station be configured to be split.
However, in the above-described conventional configuration, the right and left intermediate part of the connecting member or the front and rear intermediate part of the grounding member and the guide member is a severable connecting part, and the three-dimensional large garbage collection station is simply divided into the front and rear or left and right. Therefore, there is a problem that each of the divided bodies is easily bulky, is difficult to carry and load and unload from the trailer, and is difficult to assemble the divided bodies.
Therefore, the present invention provides a beach cleaner garbage collection station which is difficult to be bulky after being divided and can be easily installed.

As a means for solving the above problems, the invention described in claim 1 is provided with a mountain-shaped guide member (for example, the guide member 44 of the embodiment) on each of a pair of ground members (for example, the ground member 43 of the embodiment), and Each grounding member is integrally connected by a connecting member (for example, the connecting member 42 of the embodiment), and is a beach cleaner (which is pulled by a towing vehicle (for example, the vehicle 1 of the embodiment) and travels on sand and collects garbage. For example, in the beach cleaner garbage collection station (for example, the garbage collection station 40 of the embodiment) that allows the beach cleaners 20 and 50) of the embodiment to ride and collect the garbage collected by the beach cleaner, the connecting member a connecting portion for connecting the ends of the ground member removably (e.g. coupling of example pipe 46), the connecting portion is insertable end portion of the coupling member A tubular, while inserting the connecting member to the connecting portion, together with the locking member extending therethrough (e.g. engaging pins 47 in the embodiment) is inserted, that the locking member is inserted into the sand Features.

According to the present invention , by allowing the grounding member and the guide member to be divided into the main structure and the connecting member, each divided body becomes planar and difficult to be bulky after being divided. In addition, it is easy to load and unload to and from the trailer, and it is easy to assemble the divided bodies, thereby facilitating the installation work.

According to this invention , while a locking member connects a connection member and a connection part so that insertion / extraction is impossible, the movement with respect to the sandy ground of a garbage collection station can be suppressed.

The vehicle 1 can pull a trailer 13 that transports first and second beach cleaners 20 and 50 and a garbage collection station 40 described later.
The trailer 13 has, for example, a pair of left and right wheels 15 on both lower sides of the body frame 14, and has a shallow box-shaped carrier 16 that opens upward and downward on the body frame 14. A pulling arm 17 is extended from the lower front side toward the front. A hitch coupler 17 a corresponding to the trailer hitch 11 is provided at the front end portion of the pulling arm 17.

  At the upper edge portions on both the left and right sides before and after the carrier 16, a receiver 16 a that supports each connection pipe 46 described later in the dust collection station 40 is provided. The receptacle 16a has a V-shaped recess that opens upward, and the connecting pipe 46 in the garbage collection station 40 in a stacked state upside down is dropped and held in the recess. On the loaded garbage collection station 40, for example, a second beach cleaner 50 is mounted in a state in which movement is restricted by engaging with a grounding member 43 described later, and accommodated in the carrier 16, for example. The first beach cleaner 20 is mounted in the state.

  The beach cleaners 20 and 50 and the garbage collection station 40 shown in FIG. 1 indicate the state of loading on the trailer 13, and the beach cleaners 20 and 50 and the garbage collection station 40 shown in FIG. The usage state is shown above. In addition, the line GL in the figure is the ground (the upper surface of the sand), and the line CL in the figure is the vehicle 1 and the beach cleaners 20 and 50 pulled by the vehicle 1 and the garbage collection station 40 (hereinafter referred to as a vehicle or the like) that passes these. The left and right centers are indicated, the arrow FR indicates the front in the traveling direction (front-rear direction) of the vehicle, the arrow UP indicates the upper direction in the vertical direction of the vehicle, and the arrow LH indicates the left side in the horizontal direction of the vehicle. .

  Each of the beach cleaners 20 and 50 is pulled by the vehicle 1 and travels on a sandy area (sandy beach) such as a coast, and collects various kinds of garbage scattered on the sandy area. The garbage collected by the beach cleaners 20 and 50 is collected together at a garbage collection station 40 installed at a predetermined location on the sand. Each of the beach cleaners 20 and 50 and the dust collection station 40 are appropriately assembled by using a plurality of types of steel materials such as stainless steel using a joining means such as welding. Each beach cleaner 20, 50 may be pulled by a tractor.

  As shown in FIGS. 2 and 3, the first beach cleaner 20 has a plurality of (for example, fifteen) vertical members 21 extending along the traveling direction and arranged in a width direction (left and right direction) at substantially equal intervals. A plurality of sand pins 23 that form a frame 22 and project downward from each vertical member 21 are detachably attached. The first beach cleaner 20 has a symmetrical configuration.

The vertical member 21 is formed, for example, by arranging a circular steel pipe (or a square steel pipe) along the front-rear direction, and bending the front-rear end part obliquely upward forward or rearward. A plurality of the vertical members 21 are juxtaposed side by side so as to overlap in a side view, and the front end of the vertical member 21 is joined to a front horizontal member 24a made of, for example, a square steel pipe extending in the left-right direction obliquely from below and rear, and the rear end Are connected to the rear lateral member 24b made of, for example, a square steel pipe extending in the left-right direction, obliquely from the lower front side.
The frame 22 including the vertical members 21 and the horizontal members 24a and 24b is formed in a horizontally long rectangular shape when viewed from above. The left and right width of the frame 22 is set to be equal to or slightly larger than the left and right width of the vehicle 1 and narrower than the left and right width between the left and right side structures 41 of the dust collection station 40 described later.

The sand pin 23 can be attached to the front part, front-rear intermediate part, and rear part of each vertical member 21. That is, a plurality of sand pins 23 can be arranged in three rows in the front and rear direction. As a result, running resistance during low-speed running can be suppressed, and the running resistance can be further reduced by reducing the number of sand pins 23 according to the hardness of the sand. The protruding length of each sand pin 23 from the lower surface of the frame 22 is set to a maximum of 100 mm in order to suppress the influence on the ecosystem in the sand.
As the first beach cleaner 20 travels through the sand, scattered and relatively large garbage (rope, net, driftwood, etc.) is scraped and collected by being caught or entangled with each sand pin 23.

  Referring also to FIG. 4, the sand pin 23 includes a plate-like member 25 that is curved so as to be aligned with the lower outer surface of the vertical member 21, a pin main body 26 that vertically penetrates the plate-like member 25, and the pin main body 26. A brace-like support member 27 straddling the lower part of the plate-like member 25 and the rear part of the plate-like member 25 is formed in a triangular shape in a side view that is thinner toward the lower side. The upper portion of the pin body 26 is a male screw portion 26a. With the male screw portion 26a penetrating the vertical member 21 from below and protruding upward, the plate-like member 25 contacts the lower surface of the vertical member 21. In this state, the sand pin 23 is fixed to the vertical member 21 by screwing and tightening the cap nut 28 on the male screw portion 26a. A cylindrical collar 29 is inserted and fixed in a portion of the vertical member 21 through which the pin body 26 penetrates.

  In addition, as shown in FIG. 5, what is necessary is just to use the sand pin 23 'corresponding to this with respect to the vertical member 21' which consists of a square steel pipe. That is, the sand pin 23 ′ has a plate-like member 25 ′ having a U-shaped cross section so as to align with the lower outer surface of the vertical member 21 ′, and the plate-like member 25 ′ is aligned with the lower part of the vertical member 21 ′. In this state, the sand pin 23 ′ is fixed to the vertical member 21 ′ by screwing and tightening the cap nut 28 onto the male screw portion 26 a. The vertical member 21 ′ has a relatively wide left-right width in the cross-sectional shape, and by using such a vertical member 21 ′, the sliding performance of the first beach cleaner 20 with respect to the sand is improved. Further, if the folded portion 26b is formed by bending the lower end portion of the pin body 26 forward, the dust collecting ability is further improved.

With the lower part of the upper block 34b aligned with the upper rear side of 34a ', the upper and lower blocks 34a' and 34b are connected and fixed via the connecting bolt 35b. The weight 34 'is set to be heavier than the weight 34. In addition, when each wheel idles with respect to sandy ground, a tire chain may be attached to each wheel.

  Referring to FIGS. 2 and 3, a towing portion 37 for towing the first beach cleaner 20 with the vehicle 1 is provided, for example, in front of the third vertical member 21 from the left and right outer ends of the frame 22. The traction portion 37 is a thick plate-shaped member orthogonal to the left-right direction, and a plurality of (for example, three) connection holes 37a are formed so as to be aligned along the inclination of the front end portion of the vertical member 21. One of these connection holes 37 a is connected to the other end of a traction rod 38, one end of which is connected to the trailer hitch 11 of the vehicle 1, and the first beach cleaner 20 is connected to the vehicle 1 via the traction rod 38. Towed (see FIG. 25).

  At this time, it is possible to set an optimum traction position according to the sinking of the first beach cleaner 20 into the sand or the like, depending on which of the connection holes 37a the other end of the traction rod 38 is connected to. Referring also to FIG. 14, the traction rod 38 extends in a V shape or a Y shape as viewed from above from one end side connected to the trailer hitch 11 toward the left and right traction portion 37. The hitch coupler 17a corresponding to the trailer hitch 11 is provided.

  On the left and right outer sides of the frame 22, a lift arm 39 that protrudes from the outer end toward the left and right outwards is provided. The lift arm 39 is, for example, a frame shape having a top view shape. The left and right intermediate portions are substantially horizontal, the left and right inner portions are bent obliquely inside, and the left and right outside portions are bent obliquely below and outside. The The left and right widths between the outer ends of the left and right lift arms 39 are wider than the left and right widths between the left and right side structure 41 of the garbage collection station 40, and the first beach cleaner 20 pulled by the vehicle 1 has the left and right side structures. When entering between the bodies 41, the left and right lift arms 39 ride on the left and right side structure 41, whereby the first beach cleaner 20 is lifted up by a predetermined amount. The distance between the left and right side structure 41 is larger than the left and right width of the vehicle 1, and the vehicle 1 can pass between the left and right side structure 41.

  As shown in FIGS. 13 and 14, when the first beach cleaner 20 is lifted up in the garbage collection station 40 as described above, each sand pin 23 is sufficiently separated from the upper surface of the sand, and each sand pin 23 is The scraped garbage can be dropped onto the sand, so that the garbage can be collected together.

The garbage collection station 40 is formed by integrally connecting the left and right side structures 41 with a pair of front and rear connection members 42, and has, for example, a front-rear object and a symmetrical configuration.
The left-right part structure 41 is provided with, for example, a guide member 44 made of, for example, a circular steel pipe having a gentle mountain shape that is substantially symmetrical in the front-rear direction in a side view on a bar-shaped grounding member 43 made of, for example, a circular steel pipe along the front-rear direction. The front and rear end portions of the members 43 and 44 are integrally connected to each other.

  A foot member 45 is attached to the front and rear ends of the left and right grounding members 43 so as to be attachable and detachable so as to be positioned on the left and right outer sides as viewed from above.

The left and right width between the outer ends of the front ski plate 74 of the left and right front ski legs 71 is substantially the same as the left and right width of the frame 53, and the left and right width between the outer ends of the rear ski plates 79 of the left and right rear ski legs 76 is 53 is made narrower than the lateral width of 53.

  Front and rear lift arms 81a and 81b are provided on the left and right outer sides of the front and rear sides of the frame 53 so as to project from the outer end toward the left and right sides. Each of the lift arms 81a and 81b is a frame-shaped frame having a horizontally long shape when viewed from the top, for example. The left and right middle portions are substantially horizontal, the left and right inner portions are obliquely inward and the left and right outer portions are obliquely downward. Each bend is formed outward. The left and right widths between the outer ends of the lift arms 81a and 81b are wider than the left and right widths between the left and right side structures 41 of the garbage collection station 40 (in other words, the left and right lift arms 39 of the first beach cleaner 20). When the second beach cleaner 50 enters between the left and right side structures 41, the lift arms 81 a and 81 b ride on the left and right side structures 41. Thus, the second beach cleaner 50 is lifted up by a predetermined amount.

  When the second beach cleaner 50 is lifted up at the garbage collection station 40 as described above, the net 56 at the rear of the frame 53 rises to a predetermined height, and the net 56 is rotated through the hinge 82 on the left side. By moving it (see FIG. 18), it becomes possible to easily collect the dust collected in the net 56. In the second beach cleaner 50, it is possible to perform the dust collection work even in a ground contact state where the lift-up is not performed.

  Referring to FIGS. 21 and 22, the rear lift arm 81 b on the left side of the frame 53 is provided with a rear hinge bracket 83 that constitutes a part of the hinge 82 that rotatably supports the left side portion of the net 56. The rear hinge bracket 83 extends in the front-rear direction of the rear end side of the rear lift arm 81b, and has a front-rear wall 84 standing upward at the front-rear end, and a front end side of the front-rear wall 84 for the hinge shaft 82a. A front and rear through hole 84a is formed. A rear hinge pipe 85 provided on the left side of the mesh body 56 corresponding to the rear hinge bracket 83 is disposed between the front and rear walls 84, and the rear hinge pipe 85 is connected to the rear hinge bracket 82 via a hinge shaft 82a along the front and rear direction. 83 is rotatably supported by the shaft 83.

  Further, a frame-shaped support arm 86 having a lateral width reduced with respect to the lift arm 81b is provided slightly in front of the rear lift arm 81b. The support arm 86 has the same structure as that of the rear hinge bracket 83. A front hinge bracket 87 having a configuration is supported. The front and rear walls 88 of the front hinge bracket 87 are formed with front and rear through holes 88a for the hinge shaft 82a. A front hinge pipe 89 provided on the left side of the net 56 corresponding to the front hinge bracket 87 is disposed between the front and rear walls 88, and the front hinge pipe 89 is connected to the front hinge bracket via a hinge shaft 82a along the front and rear direction. 87 is rotatably supported. The hinge pipes 85 and 89 and the hinge shaft 82a are provided coaxially with each other.

  As shown in FIGS. 16 and 17, the net body 56 has a box shape that opens forward and upward, and is formed by attaching a wire net having a mesh of a predetermined size to a frame type frame mainly composed of a steel pipe, for example. The net 56 is provided so as to have substantially the same left-right width as the frame 53 in the left-right direction from a position slightly forward of the front-rear center of the frame 53 to the vicinity of the rear end of the frame 53 in the front-rear direction. Here, the position of the front end of the net 56 is 100 to the rear from the vicinity of the rear end of each keel 54, that is, from the vicinity of each scraper 55, so that the sand and dust wound up by each keel 54 and the scraper 55 can be collected well. Separate about 300 mm. More preferably, the front end position of the net 56 is spaced apart from the vicinity of the rear end of each keel 54 by about 250 mm.

  Referring also to FIG. 18, the net 56 includes a bottom wall portion 92 that has a horizontally long rectangular shape in a top view, a rear wall portion 93 that rises substantially vertically from the rear edge of the bottom wall portion 92, and a bottom wall portion. The left and right side wall portions 94 rise up slightly inclined so as to be positioned on the left and right outer sides from the both side edges of 92. The rear wall portion 93 and the left and right side wall portions 94 open and surround the periphery of the bottom wall portion 92 only on the front side so that the dust rolled up by the keels 54 and the scraper 55 can be collected on the bottom wall portion 92. Form.

The front portion of the bottom wall portion 92 is an inclined portion 92a that is inclined slightly forwardly downward, and the portion that is behind the inclined portion 92a is an approximately horizontal horizontal portion. The horizontal portion is divided into a front horizontal portion 92b and a rear horizontal portion 92c with a horizontal member extending in the left-right direction as a boundary.
Here, a wire mesh having a mesh size of 25 mm is attached to the inclined portion 92a of the bottom wall portion 92, a wire mesh having a mesh size of 12 mm is attached to the front horizontal portion 92b, and a wire mesh having a mesh size of 8 mm is attached to the rear horizontal portion 92c. Is done.

  In this way, by setting the mesh size of the wire mesh of the bottom wall portion 92 as coarse as the front side, among the sand rolled up by each keel 54 and the scraper 55, sand containing relatively heavy moisture, etc. Since it does not reach the rear side of the 92, it is satisfactorily screened without causing clogging or the like through the coarse wire net in the inclined portion 92a on the front side of the bottom wall portion 92. On the other hand, the relatively light dry sand and the like reach the horizontal portion on the rear side of the bottom wall portion 92 together with the dust, and the sand and the like are screened through the middle and fine wire nets attached thereto. Good collection without dropping off the mesh. Each wire mesh can be appropriately replaced within a range of mesh sizes of 6, 8, 10, 12, 25 mm.

  The side wall portion 94 of the net 56 is formed with a rectangular side wall main body 94a that is long in the front-rear direction in the side view above the both side edges of the bottom wall portion 92, and has a trapezoidal shape in the side view above the rear side of the side wall main body 94a. A rear protrusion 94b is formed. The rear side portions of the side wall main body 94a and the rear projecting portion 94b are arranged in a straight line substantially perpendicular to the side view, and the rear wall portion 93 of the net 56 is provided with these rear side portions as side portions. The upper side part of the side wall part 94 (rear protrusion part 94b) and the upper side part of the rear wall part 93 are substantially the same height.

  Front and rear hinge plates 95a and 95b are provided in front of and behind the left side wall 94 of the net 56 so as to straddle the middle and lower frame members of the side wall body 94a. Each of the hinge plates 95a and 95b is a plate having a substantially square shape when viewed from the side. To form a reinforcing flange. Front and rear hinge pipes 85 and 89 are integrally joined to the outer surfaces of the hinge plates 95a and 95b, respectively.

  On the front upper side of the left and right side wall portions 94 (above the front hinge plate 95a in the left side wall portion 94), a handle 96a protruding upward from its upper edge is provided. The handle 96a has a U-shape that opens downward in a side view, and is inclined so that its upper side extends along the front-rear direction and projects slightly outward from the corresponding side wall 94. Further, on the upper left and right sides of the rear wall portion 93, a handle 96b protruding upward from the upper edge thereof is provided. The handle 96b has a U-shape that opens downward when viewed from the rear, and is provided substantially vertically so that its upper side extends along the left-right direction and is positioned substantially on the same plane as the rear wall 93.

  As described above, the left side portion of the mesh body 56 is rotatably connected to the left side portion of the frame 53 via the hinge 82, and the hinge 82 is lifted so that the right side of the mesh body 56 is lifted upward. If the net body 56 is rotated through the bottom wall portion 92 so that the bottom wall portion 92 is in an upright state, dust collected in the net body 56 falls on the left side wall portion 94, and the left side wall portion 94. The dust is discharged out of the net 56 along the way.

  At this time, by providing the handles 96a and 96b at each part (at least on the side opposite to the hinge 82) of the surrounding part 91 of the net 56, it is easy to collect dust by rotating the net 56. . In addition, since the hinge 82 is arranged on one short side (left side) of the horizontally long net 56, the length from the rotating shaft when raising the net 56 to the operation unit (right handle) is secured. Thus, the rotation operation of the net 56 is facilitated.

  The left side wall portion 94 of the mesh body 56 (in other words, the wall portion on the hinge 82 side of the enclosure portion 91) is a wall portion on which a plate member is mounted in order to favorably discharge the dust. The upper edge portion of the left side wall portion 94 of the net 56 is set so as to protrude to the left of the outside of the dust collection station 40 in the standing state (see FIG. 18), and is adjacent to the left side of the dust collection station 40. If the waste collection container is arranged, the waste collected in the net 56 can be directly thrown into the container with the left side wall portion 94 as a slope. Note that the right side wall portion 94 and the rear wall portion 93 of the net body 56 are, for example, net portions to which coarse metal nets are attached in order to prevent the dust thrown into the net body 56 from dropping off.

  On the left and right vertical members 51 in the frame 53, left and right front ends or rear end stoppers 97a and 97b for positioning the front and rear ends of the net 56 on both left and right sides are provided. Each stopper 97a, 97b has a substantially vertical position restricting surface that contacts the front end or the rear end of the mesh body 56, and a rotation guide surface that is inclined upwardly and continuously above it. The member 51 is detachably attached.

  The position restricting surface of the left and right front end stopper 97a is in contact with both sides of the front end of the net 56 in use (a state where the bottom wall portion 92 is substantially horizontal and is in contact with the frame 53). The rear end side of the net 56 in use is in contact with the position restricting surface 97b, so that the net 56 is positioned in the front-rear direction with respect to the frame. Further, when the mesh body 56 is rotated to return from the standing state to the use state, both the front and rear ends are guided by the guide surfaces of the stoppers 97a and 97b, and the mesh body 56 is placed at a predetermined position on the frame 53. Returned to smooth.

  As shown in FIG. 23, the positions where the stoppers 97a and 97b are attached to the vertical member 51 may be movable back and forth. At this time, for example, the length of the front and rear hinge pipes 85 and 89 on the left side of the net 56 is made shorter than the distance between the front and rear walls 84 and 88 of the front and rear hinge brackets 83 and 87, etc. Thus, the net 56 can also be moved back and forth. Thus, the dust collecting ability of the second beach cleaner 50 can be improved by making it possible to easily change the front end position of the net 56 according to the sand.

Next, an outline of a procedure for cleaning the sandy beach using each of the beach cleaners 20 and 50 will be described.
First, as shown in FIG. 1, a garbage collection station 40 mounted on the trailer 13 and transported is installed at a predetermined position on the sand beach. Here, in FIG. 1, the dust collection station 40 can be mounted on the trailer 13 in an assembled state, but this is mounted in a state of being divided into the side structure 41 and the connecting member 42 as described above. Of course, in this case, installation work of the garbage collection station 40 including loading and unloading with respect to the trailer 13 is facilitated. Note that only the foot member 45 is removed from the dust collection station 40 in FIG.

  Next, the hardness of the sand beach which is a reference for determining the number of sand pins 23 of the first beach cleaner 20 and the amount of each keel 54 and scraper 55 submerged in the sand of the second beach cleaner 50 is measured. This measurement is performed by, for example, allowing a steel pile of a predetermined size to fall freely on a sand beach from a predetermined height, and evaluating the sand beach hardness, for example, in three stages (soft, standard, and hard) from the average value of the measurement results. . The number of sand pins 23, the weight of the weight 34, the height of each ski leg, and the connecting rod 38 to the traction portions 37 and 67 are determined according to the hardness of the sandy beach and the state of scattered dust. Determine the connection position.

  Next, after the first beach cleaner 20 is lowered from the trailer 13 and set based on the measurement result of the hardness of the sandy beach, the first beach cleaner 20 is pulled by the vehicle 1 and travels on the sandy beach at a constant speed. . As shown in FIG. 24, the traveling trajectory of the vehicle 1 and the first beach cleaner 20 at this time moves the turning position while turning in a substantially square shape within a predetermined range on the sand surface. It can be surely cleaned without unevenness. Since the first beach cleaner 20 collects relatively large garbage on the sand beach while each sand pin 23 is biting into the sand, the running resistance is relatively large, and the running speed is as low as about 5 to 10 km / h. Is set.

  As described above, when the first beach cleaner 20 travels on the sand beach and a predetermined amount of garbage is collected under the frame 22, the first beach cleaner 20 returns to the garbage collection station 40 and collects the collected garbage. Work is done. At this time, when the first beach cleaner 20 enters between the left and right side structures 41 after the vehicle 1 passes between the left and right side structures 41 of the garbage collection station 40, the left and right lift arms 39 are moved to the left and right side structures. 41, the first beach cleaner 20 is lifted up by a predetermined amount (see FIG. 13). In this state, the vehicle 1 and the first beach cleaner 20 are stopped, and after collecting the dust dropped on the sand, the vehicle 1 and the first beach cleaner 20 are run again to repeat the above-described dust collecting operation. .

  After the predetermined range of cleaning is performed by the first beach cleaner 20, the second beach cleaner 50 is pulled to the same range to collect relatively small dust on the sand beach. Thus, by using the second beach cleaner 50 after the first beach cleaner 20, damage to the keel 54, the scraper 55, the net 56, and the like corresponding to fine dust can be suppressed. The traveling locus of the second beach cleaner 50 is the same as that of the first beach cleaner 20. Further, the second beach cleaner 50 is softened by digging up the sandy beach by the action of the first beach cleaner 20 during traveling, and it is necessary to wind up sand and dust by each keel 54 and scraper 55. The traveling speed is set to 15 to 25 km / h, which is slightly faster than the first beach cleaner 20.

  As the second beach cleaner 50 runs on the sandy beach, relatively small dust is rolled up by the keels 54 and the scraper 55 together with the sand, and these are collected in the net 56 at the rear of the frame 53. At this time, since the mesh size of the wire mesh is set to become smaller in order from the front side of the bottom wall portion 92 of the mesh body 56, collected dust is difficult to fall and clogging of the wire mesh is suppressed.

  As described above, when the second beach cleaner 50 travels on the sand beach and a predetermined amount of garbage is collected in the net 56, the second beach cleaner 50 returns to the garbage collection station 40, and the collected garbage is collected. Collection work is performed. At this time, when the second beach cleaner 50 enters between the left and right side structures 41 after the vehicle 1 passes between the left and right side structures 41 of the garbage collection station 40, the left and right lift arms 81a and 81b before and after the second beach cleaner 50 move left and right. The second beach cleaner 50 is lifted up by a predetermined amount after riding on the side structure 41. In this state, the vehicle 1 and the second beach cleaner 50 are stopped, the net 56 is rotated, and the collected dust is collected. Then, the vehicle 1 and the second beach cleaner 50 are run again, and the above-described dust is collected. Repeat the collection process.

  As described above, the garbage collection station 40 in the above embodiment is provided with the mountain-shaped guide member 44 in the side view in each of the pair of left and right grounding members 43 and the bar-shaped coupling member 42 between the grounding members 43. The beach cleaners 20 and 50, which are integrally connected and are towed by the towing vehicle 1 and run on the sand and collect the garbage, can be picked up, and the garbage collected by the beach cleaners 20 and 50 can be collected. And a connecting pipe 46 that detachably connects the end of the connecting member 42 and the grounding member 43.

  According to this configuration, by allowing the grounding member 43 and the guide member 44 to be divided into the main side structure 41 and the connecting member 42, each divided body becomes planar, and is difficult to be bulky after the division. In addition, it is easy to carry each segment and load / unload the trailer 13 and to assemble the segments, thereby facilitating the installation work.

  In the garbage collection station 40, the connection pipe 46 has a cylindrical shape into which an end of the connection member 42 can be inserted, and penetrates through the connection pipe 42 with the connection member 42 inserted. When the locking pin 47 is inserted and the locking pin 47 is inserted into the sand, the locking pin 47 connects the connecting member 42 and the connecting pipe 46 so that they cannot be inserted and removed, and the dust collection station 40 is connected to the sand. Movement can be suppressed.
