  Since the dust collection body 100 is supported by a subframe 83 that can swing up and down, the dust collection body 100 is configured to swing up and down about a pivot shaft 83e of the subframe 83. A pair of left and right driving force conversion / transmission mechanisms 90 that convert the rotational driving force of the wheels 80 into vibration force and transmit this vibration to the dust collection member 100 are provided behind the dust collection member 100. The dust collection body 100 vibrates around the rotation shaft 83e of the subframe 83 by the driving force conversion / transmission mechanism 90.

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, the beach cleaners 20 and 50, the dust collection station 40, and the drum type sieve body 200 are loaded on the trailer 13 and transported to a predetermined cleaning work place. Here, the beach cleaners 20 and 50 are loaded on the trailer 13 in an assembled state, while the garbage collection station 40 includes left and right front and rear divided bodies 41a and 41b, a right intermediate divided body 41d, and front and rear connected parts. It is loaded on the trailer 13 in a state of being divided into the member 42 and each foot member 45.

  More specifically, first, a set of front and rear divided bodies 41a and 41b (or a set of front or rear divided bodies) is placed on the trailer 13 (accommodated in the loading platform 16), and then each beach cleaner 20, 50 is placed. Then, the drum type sieve body 200 is placed on the trailer 13. At this time, the first beach cleaner 20 has both side portions of the front and rear lateral members 24a and 24b of the frame 22 to the left and right side portions 16b and 16c of the loading platform 16 (upper side portion 44c of the guide member 44 of the dust collection station 40). It is loaded in a loaded state.

  The second beach cleaner 50 is loaded with the vertical member 51 of the frame 53 placed on the front and rear horizontal members 24a and 24b of the first beach cleaner 20 in the loaded state and inclined slightly downward. Each keel 54 abuts against the front lateral member 24a of the first beach cleaner 20 from the front, so that the rearward movement of the second beach cleaner 50 is restricted.

  In the garbage collection station 40, another set of front and rear divided bodies 41a and 41b (or a set of front or rear divided bodies) and a right intermediate divided body 41d are arranged in front of the second beach cleaner 50 in the loaded state. It mounts so that it may overlap with the part inclination part 57 and the scraper frame 58. Further, each connecting member 42 is mounted, for example, on the right side of the loading platform 16 in a state of being lowered forward, and each foot member 45 is accommodated, for example, on the left rear side of the loading platform 16.

  The loading state of the garbage collection station 40 is not limited to the above-described one, and only the right intermediate divided body 41d is mounted above the front inclined portions 57 and the scraper frame 58 of the second beach cleaner 50 in the loading state. For example, the pair of front and rear divided bodies 41a and 41b are mounted so as to be aligned in the left-right direction behind the second beach cleaner 50, and the other set of front and rear divided bodies 41a and 41b are mounted in the loading platform 16. Also good. At this time, the foot members 45 are housed by being appropriately distributed on the left and right of the rear part of the loading platform 16.

  Next, the loaded beach cleaners 20 and 50 and the drum type sieve body 200 are lowered to the ground. At this time, the rear divided body 41 b is connected to the left and right side portions 16 b and 16 c of the loading platform 16 of the trailer 13 to obtain the loading and unloading work state, and the beach cleaners 20 and 50 in the loaded state along the left and right guide members 44. , The beach cleaners 20 and 50 can be lowered to the ground relatively easily even when they are in a state of being integrally assembled, and the process can be quickly transferred to the garbage collection operation. Can do.

  Next, the garbage collection station 40 is installed at a predetermined position on the sand beach. First, one rear division body 41b is removed from the left side portion 16b of the loading platform 16 of the trailer 13 in the unloading work state, and the rear division body 41b, the right intermediate division body 41d, and the front division body 41a are removed. The right side structure 41R is configured by coupling. On the other hand, the left side structure 41L is configured by connecting the front divided body 41a to the right side 16c of the loading platform 16 of the trailer 13.

  The left and right side structures 41R and 41L are connected via the front and rear connecting members 42, and the foot recovery members 40 are assembled as the installation state by attaching the foot members 45 to predetermined positions. At this time, by loading the relatively large garbage collection station 40 on the loading platform 16 in a state of being divided into a plurality of divided bodies, the loading / unloading operation of the garbage collection station 40 with respect to the trailer 13 can be facilitated. .

  Next, the first beach cleaner 20 is pulled by the vehicle 1 and travels on the sand beach at a constant speed, thereby collecting relatively large garbage on the sand beach. 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 41R and 41L after the vehicle 1 passes between the left and right structures 41R and 41L of the garbage collection station 40, the left and right sides of the frame 22 are moved. Rides on the left and right side structures 41R and 41L, and the first beach cleaner 20 is lifted up by a predetermined amount (see FIG. 3). Then, the vehicle 1 and the first beach cleaner 20 are stopped and dropped onto the sand surface with the first beach cleaner 20 riding on the upper sides 44c of the guide members 44 of the left and right side structures 41R and 41L. After performing the dust collection operation, the vehicle 1 and the first beach cleaner 20 are run again to repeat the above-described dust collection 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 dust collecting body 100, and the like corresponding to fine dust can be suppressed. The second beach cleaner 50 is softened by digging up the sand beach by the action of the first beach cleaner 20 during traveling, and it is necessary to scrape 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 garbage is scraped up by the keels 54 and the scraper 55 together with the sand, and these are collected in the garbage collection body 100 at the rear of the frame 53.
While the second beach cleaner 50 is traveling, the dust collecting body 100 vibrates up and down by the driving force converting / transmitting mechanism 90. Therefore, the sand collected in the garbage collection body 100 is screened off from the garbage collection body 100 by the up and down vibrations, so that the accumulation of sand in the garbage collection body 100 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 garbage collection body 100, the second beach cleaner 50 returns to the garbage collection station 40 once, and the collected garbage is collected. The collection work is performed. At this time, when the second beach cleaner 50 enters between the left and right side structures 41R and 41L after the vehicle 1 passes between the left and right structures 41R and 41L of the garbage collection station 40, the left and right lift arms 81a before and after the second beach cleaner 50 enter. , 81b ride on the left and right side structures 41R, 41L, and the second beach cleaner 50 is lifted up by a predetermined amount. Then, the vehicle 1 and the second beach cleaner 50 are stopped with the second beach cleaner 50 riding on the upper sides 44c of the guide members 44 of the left and right side structures 41R and 41L, and the garbage collection body 100 is moved to the side. Then, the vehicle 1 and the second beach cleaner 50 are run again to repeat the above-described dust collection operation.

  Here, when collecting the collected garbage by rotating the garbage collection body 100, the garbage is directly put into the loading platform 16 of the trailer 13 adjacent to the left side of the garbage collection station 40. Therefore, the loading platform 16 can be used as a garbage collection container, and the collected garbage can be transported by the trailer 13 after the cleaning work is completed. Can be reduced.

Garbage collected by each beach cleaner 20, 50 may require sand separation work. Further, in areas where the vehicle 1 cannot travel, such as when there is a rocky part of the sand, the first and second beach cleaners 20 and 50 may not be able to collect garbage. In these cases, the drum type sieve body 200 is attached to the trailer 13, and the dust collected by the beach cleaners 20 and 50 and the garbage collected from the sand by a scoop or the like are thrown into the drum type sieve body 200. By rotating the drum type sieve body 200, sand and dust are separated.
Hereinafter, the trailer 13 to which the drum type sieve body 200 is attached will be described.

Each circumferential groove 206 is formed so that the width thereof is substantially the same as the width of the guide roller 217. The drum-type sieve body 200 is rotatably supported by the support tool 210 by fitting the guide roller 217 into these circumferential grooves 206. The drum type sieve body 200 is supported by the support 210 so that the lower frame 201b is positioned on the lower side (right side in the present embodiment) of the pair of left and right guide rollers 217.

  As described above, since the drum-type sieve body 200 is supported by the guide roller 217, even the drum-type sieve body 200 having a large capacity can be easily rotated, so that the work for separating sand and dust is easy. At the same time, it is possible to perform a larger amount of separation work at one time than when sieving by hand. Since the guide roller 217 is fitted in the circumferential groove 206 of the drum type sieve body 200, the movement of the drum type sieve body 200 in the axial direction is restricted, and the drum type sieve body 200 can be stably held. When the drum-type sieve body 200 is rotated, the lump of sand is broken by the rod 205, the sand and dust are efficiently separated, and the sand is sieved off from the net member 204.

  At this time, since the drum-type sieve body 200 is disposed obliquely and the bottom plate 202 is provided at the bottom of the lower side, the dust thrown into the drum-type sieve body 200 does not spill out during the separation operation. Only the dust is accumulated on the bottom plate 202, and when collecting the dust, the bottom plate 202 of the drum-type sieve body 200 is opened so that the dust collected in the drum-type sieve body 200 is adjacent to the drum-type sieve body 200. It falls onto the bottom wall part 16e of the part 16. Using this bottom wall portion 16e, the worker can separate the collected garbage into combustible materials and non-combustible materials.

  As shown in FIG. 11, the drum-type sieve body 200 is supported by the support 210, and the outer periphery of the upper frame 201 a is in contact with the upper portion of the wheel 15. Accordingly, when the wheel 15 is rotated by pulling the trailer 13, the drum type sieve body 200 automatically rotates in a direction B opposite to the rotation direction A of the wheel 15. Therefore, when the trailer 13 is towed, it is not necessary to rotate the drum type sieve body 200. Therefore, the operator moves the dust mixed with sand with a scoop while moving with the trailer 13 in the drum type sieve body 200. By simply putting it in the trash, the trash can be separated and collected from the sand, and the trash can be collected efficiently.

  Note that when the drum-type sieve body 200 is rotated to separate dust and sand, the bottom wall 16e on the left side of the trailer 13 is removed. Thereby, the sand falling from the drum-type sieve body 200 is discharged from the bottom of the trailer 13 to the outside of the trailer 13, and the sand does not accumulate inside the trailer 13.

  As described above, according to the present embodiment, the pair of left and right wheels 15 are provided in the lower part of the loading platform 16, the support frame and the support tool provided on the support frame are provided on the body frame 14 of the loading platform 16. 210, a cylindrical drum-type sieve body 200 having a removable bottom plate 202 at one end and an open end at the other end is rotatably supported by a guide roller 217, and an outer peripheral portion of the drum-type sieve body 200 Was brought into contact with the wheel 15. Accordingly, even the drum-type sieve body 200 having a large capacity can be easily rotated, so that the work for separating the sand and the dust becomes easy, and compared with the case where it is sieved by human hands. It is possible to separate a lot of garbage. Further, when the trailer 13 is run, the drum-type sieve body 200 automatically rotates as the wheels 15 of the trailer 13 rotate, so that the operator can move the sand-mixed dust while moving with the trailer 13 to the drum-type sieve body. By simply throwing it into 200, the garbage can be separated and collected from the sand, and the garbage can be collected efficiently.

  Moreover, according to the said embodiment, the rotating shaft of the drum-type sieve body 200 was inclined, and the bottom plate 202 side was made lower. The support frame of the support 210 includes a pair of left and right vertical members 211, a pair of horizontal members 212, a pair of subframes 216 extending in parallel with the horizontal member 212 in plan view and inclined in side view, and a guide roller. 217, and the guide roller 217 was attached to the pair of subframes 216 such that the roller axis thereof was parallel to the subframe 216. Thereby, during the separation work, the dust thrown into the drum type sieve body 200 can be prevented from spilling outside, and the drum type sieve body can be opened by opening the bottom plate 202 of the drum type sieve body 200 when collecting the garbage. Since the trash accumulated in 200 can be collected on the loading platform 16, the separation and collection of the trash becomes easy.

  Further, according to the above embodiment, since the rod 205 is provided inside the drum type sieve body 200, a lump of sand is broken by the rod 205 during the separation operation, so that the separation efficiency can be improved.

  Furthermore, according to the above-described embodiment, at least two or more circumferential grooves 206 are formed on the outer periphery of the drum type sieve body 200, and the guide roller 217 of the support tool 210 is fitted into the circumferential grooves 206. Since the movement in the axial direction due to the rotation of the drum type sieve body 200 is restricted, the drum type sieve body 200 can be stably held.

However, the above embodiment is an aspect of the present invention, and it is needless to say that the embodiment can be appropriately changed without departing from the gist of the present invention.
For example, in the above embodiment, the bottom wall portion 16e on the left side of the loading platform portion 16 is removed, and the drum type sieve body 200 is attached to the vehicle body frame 14 on the left side of the loading platform portion 16 via the support 210. The right bottom wall 16e may be removed, and the drum-type sieve body 200 may be attached to the right body frame 14 of the loading platform 16 via the support 210. In this case, the support 210 may be arranged by placing the rising part 215 along the right side wall part 16d and inclining the drum type sieve body 200 downwardly to the left.

  In the above embodiment, the protrusion is described as the rod 205 of the circular steel pipe. However, the protrusion is not limited to this shape, and the protrusion protrudes to the inside of the drum-type sieve body 200 to form a lump of sand. For example, the shape of a blade used in a mixer or the like may be used as long as it can be destroyed.

  Furthermore, in the above-described embodiment, two circumferential grooves 206 are formed in the drum-type sieve body 200, and a total of four guide rollers 217 are provided on each circumferential groove 206, one pair on the front and rear sides. Two or more circumferential grooves 206 may be formed, and four or more guide rollers 217 may be provided.

  In the above embodiment, the circumferential grooves 206 are formed in the upper frame 201a and the lower frame 201b of the drum type sieve body 200. However, as shown in FIG. 12, the circumferential grooves 206 are formed in the upper frame 201a and the lower frame 201b. Instead, the pair of rings 207 may be fitted to the outer peripheries of the upper frame 201a and the lower frame 201b. Each ring 207 includes a ring main body 207a fitted to the outer periphery of the frames 201a and 201b, and a rib 207b extending from the ring main body 207a in the radial direction of the sieve main body 201. The pair of rings 207 are arranged on the frames 201 a and 201 b so that the ribs 207 b face each other and the distance between the ribs 207 b is substantially the same as the width of the guide roller 217. The drum type sieve body 200 is rotatably supported by the support 210 by fitting the guide roller 217 to these rings 207.

  Moreover, in the said embodiment, although the wheel 15 was rotated by pulling the trailer 13, as shown in FIG. 13, the trailer 13 is supported in the state which separated the wheel 15 from the ground GL, and the wheel 15 May be rotated manually. In this case, a stand 208 is detachably attached to the trailer 13 at its four corners. For example, the stand 208 is provided with a grounding member 208a for stable installation on the sand surface at the lower end of the steel pipe, and a support portion 208b that is detachably supported by the body frame 14 at the upper end. The stand 208 is set to such a length that the wheel 15 is separated from the ground GL.

Further, the trailer 13 is formed with an exposure hole for exposing the outer surface of the wheel 15 on the side surface (side wall portion 16d and vertical frame 14a). A handle 209 formed of, for example, a pipe member having a round cross section is detachably attached to the outer surface of the wheel 15.
With this configuration, the operator can grip the handle 209 and rotate the wheel 15, so that the drum-type sieve body 200 can be easily rotated.
