  Sidewalls 21 a and 21 b of the hopper frame 21 are inclined downward toward the center of the hopper frame 21 in the width direction. As a result, the ballast located near the side walls 21 a and 21 b of the hopper frame 21 moves toward the openings 32 and 33. The side walls 21 c and 21 d of the hopper frame 21 are inclined downward toward the center of the hopper frame 21 in the longitudinal direction. Here, reference numeral 34 denotes a reinforcing material provided on the side wall 21a and the side wall 21b for the purpose of reinforcing the hopper frame 21, and reference numeral 35 denotes a ballast that moves inside the hopper frame 21 to either the opening 32 or the opening 33. It is a member for distributing to one opening.

  Similarly, the side wall 21 b of the hopper frame 21 has an outlet 40 near the opening 32 and an outlet 41 near the opening 33. As mentioned above, the outlet 40 is provided along the opening 32 and the outlet 41 is provided along the opening 33. As described above, the reinforcing material 34 is provided on the side wall 21 a of the hopper frame 21. Therefore, the discharge port 40 and the discharge port 41 are each divided into four, for example, by the reinforcing material 34. The outlet 40 is covered by the shielding plate 42, and the outlet 41 is covered by the shielding plate 43.

  The hopper frame 21 is provided with stabilizers 45 and 46. The stabilizer 45 is disposed in the vicinity of the upper side of the opening 32, and the stabilizer 46 is disposed in the vicinity of the upper side of the opening 33. Therefore, in FIG. 4 showing a top view of the hopper frame 21, the stabilizer 45 covers the opening 32 and the stabilizer 46 covers the opening 33.

  The stabilizers 45 and 46 are plate members bent upward at a position shifted by a predetermined amount from the center in the short side direction. The stabilizer 45 has a clearance D between the tip of the short piece 45a in the XZ plane and the side wall 21a of the hopper frame 21 and the clearance E between the tip of the long piece 45b in the XZ plane and the side wall 21b of the hopper frame 21 (D It is disposed above the opening 32 so that = E). That is, the area of the opening provided between the tip of the short piece 45 a of the stabilizer 45 and the side wall 21 a of the hopper frame 21 and the opening provided between the long piece 45 b of the stabilizer 45 and the side wall 21 b of the hopper frame 21 The area is set to the same area.

The diameter is set to about one or two pieces.

  By providing the above-described stabilizers 45 and 46 inside the hopper frame 21, the ballast reaching the positions of the stabilizers 45 and 46 is distributed toward the side wall 21a or 21b of the hopper frame 21 by the slopes of the stabilizers 45 and 46, respectively. Be As a result, among the ballasts loaded on the hopper frame 21, it is possible to prevent the ballast in the lower layer from being concentrated at the openings 32, 33 and clogging the ballast in the vicinity of the openings 32, 33.

  As shown in FIG. 4, in the top view of the crushed stone carrier / dispersion truck 10, in the internal structure of the hopper frame 21, the positional relationship between the opening 32 and the opening 33 with reference to the center P of the crushed stone carrier spreader 10 Is a point-symmetrical relationship. Similarly, the positional relationship between the stabilizer 45 and the stabilizer 46 is a point-symmetrical relationship. Further, the positional relationship between the screw conveyor 23 and the screw conveyor 24 is a line symmetrical relationship with reference to a straight line Q passing through the center P of the crushed stone conveying / scattering truck 10.

  Although the screw conveyors 22 and 23 and the openings 32 and 33 are hidden by the stabilizers 45 and 46 and the hopper frame in the top view in FIG. 4, the two-dot chain line and the opening 32 for the screw conveyors 22 and 23 for convenience. , 33 are shown using dotted lines.

  The control levers 48, 49, 50, 51 are provided corresponding to the four shielding plates 38, 39, 42, 43 described above. For example, the operation lever 48 is operated such that one end portion thereof is inclined toward the center in the width direction of the crushed stone conveying / dispersing wheel 10 (the position shown by the solid line in FIG. 3) It is provided so as to be pivotable between an outwardly inclined state (a position shown by a two-dot chain line in FIG. 3) in the direction. When the operating lever 48 is held at the position shown by the solid line in FIG. Further, when the control lever 48 is operated from the position shown by the solid line in FIG. 3 to the position shown by the two-dot chain line in FIG. 3, the shielding plate 38 slides to open the discharge port 36.

  Similarly, the control lever 49 slides the shielding plate 39 between the position for shielding the outlet 37 and the position for opening the outlet 37. The control lever 50 slides the shielding plate 42 between the position where the discharge port 40 is shielded and the position where the discharge port 40 is opened. The control lever 51 slides the shielding plate 43 between the position for shielding the discharge port 41 and the position for opening the discharge port 41.

  Below the openings 32 and 33 provided in the hopper frame 21, weirs 53 and 54 are provided along the longitudinal direction (Y direction) of the hopper frame 21. The screw conveyors 22 and 23 are disposed in the insides of the weirs 53 and 54, respectively.

Here, as for screw conveyors 22 and 23, the axis of rotation is arranged at the center in the width direction (X direction) of crushed stone carrier spreader 10.

  The screw conveyor 22 is connected to the drive motor 24 via a drive mechanism consisting of, for example, a drive chain and a sprocket. When the screw conveyor 22 is rotated by the operation of the drive motor 24, the ballast dropped in the weir 53 is pressed against the screw portion 22a of the screw conveyor 22 which rotates. As a result, the ballast is conveyed by the screw conveyor 22 toward the discharge port 53a from the inside of the weir 53, and then falls into the track of the rail 17 from the discharge port 53a. In addition, the discharge port 53a provided in the weir 53 may be always open, or may be opened and closed by actuation or automatically.

  Similarly, the screw conveyor 23 is connected to the drive motor 25 via a drive mechanism consisting of, for example, a drive chain and a sprocket. When the screw conveyor 23 is rotated by the operation of the drive motor 25, the ballast dropped to the weir 54 is pressed against the screw portion 23 a of the screw conveyor 23 which rotates. As a result, the ballast is conveyed by the screw conveyor 23 toward the outlet 54 a from the inside of the weir 54, and then falls into the track of the rail 17 from the outlet 54 a. In addition, the discharge port 54a provided in the weir 54 may be always open, or may be opened and closed by main action or automatic operation.

  The chutes 61 and 62 are provided below the discharge ports 36 and 37 provided on the side wall 21 a of the hopper frame 21. Further, chutes 63 and 64 are provided below the discharge port 40 and the discharge port 41 provided on the side wall 21 b of the hopper frame 21. The chutes 61, 62, 63, 64 are formed of steel plates. The chutes 61, 62, 63, 64 are inclined downward from one end portion disposed on the center side in the width direction of the hopper frame 21 toward the other end portion disposed on the outer side in the width direction of the hopper frame 21. Arranged as. By arranging such a chute 61, 62, 63, 64, after the ballast falling from the outlet 36, 37, 40, 41 moves along the chute 61, 62, 63, 64, the chute 61, 62 , 63, 64 fall out of the gauge of the rail 17.

  The operation panels 30, 31 have a plurality of operation buttons including a button for driving the drive motor 23, a button for stopping the drive of the drive motor 23, and the like. The control panels 30, 31 have monitors 30a, 31a for displaying an image captured by cameras 72, 73 described later, an image for assisting the operation of a plurality of operation buttons, and the like.

  FIG. 8 is a diagram showing an electrical configuration when transmitting and receiving a signal between the crushed stone transportation / dispersion truck 10 and the motor vehicle 11. As shown in FIG. In addition, in FIG. 8, the case where one crusher conveying scatterer 10 is connected with the motor vehicle 11 is shown. Moreover, in FIG. 8, the structure of the motor vehicle 11 is described only about the structure which performs communication between the crushed stone transportation / dispersion truck 10. As shown in FIG.

  The crushed stone transport spreader 10 includes a control unit 70, a communication unit 71, cameras 72 and 73, a spread amount detection sensor 74, and the like, in addition to the control panels 30 and 31 described above. The control unit 70 receives the operation signal from the control panel 30, 31 and controls the drive of the drive motor 24, 25 mounted on the crushed stone transportation / dispersion truck 10 and displays the monitor 30a, 31a provided on the control panel 30, 31. In addition to the control, communication control with the motor vehicle 11 is performed. The communication unit 71 transmits and receives signals by wireless communication with the motor vehicle 11. In addition to the video signals acquired by the cameras 72 and 73, the signals include signals such as control commands.

  The camera 72 is disposed in the vicinity of the outlet 53 a of the crucible 53, and the camera 73 is disposed in the vicinity of the outlet 54 a of the crucible 54. The cameras 72 and 73 pick up images (moving images or still images) with the discharge ports 53a and 54a as the imaging range. An image captured by the cameras 72 and 73 is displayed on the monitor 30 a of the operation panel 30 or the monitor 31 a of the operation panel 31 or the monitor 78 provided on the motor vehicle 11.

  The motor vehicle 11 has a control unit 76, a communication unit 77, a monitor 78, an emergency stop button 79, and the like. Control unit 77 controls each part of motor vehicle 11 in response to an operation signal from an operation panel (not shown). The communication unit 78 performs wireless communication with the crushed stone transportation / dispersion truck 10. According to this wireless communication, it is possible to receive video signals from the cameras 72 and 73 installed in the crushed stone transportation / dispersing truck 10 and transmit an emergency stop signal from the emergency stop button 79 to the crushed stone transportation / scattering truck 10 Become. The monitor 78 displays an image based on the video signal transmitted from the crushed stone transport and scatterer 10. The emergency stop button 79 is operated when stopping the drive motors 24 and 25 when it is determined that the spraying condition of the ballast to be sprayed is bad. When the emergency stop button is operated, the control unit transmits an emergency stop signal to the crushed stone transport and scatterer 10.

  In addition, in FIG. 8, although the structure in the case of transmitting / receiving the signal between 1 crusher conveying scatterer 10 and the motor vehicle 11 is represented, in the crush dispersion work, the motor vehicle 11 is 2-4. In general, it is connected to a crusher carrier scatterer 10. Therefore, wireless communication with each crushed stone transport and scatterer 10 is performed by using different communication channels in each vehicle.

  Hereinafter, the operation of the crushed stone carrier spreader 10 when the loaded ballast is sprayed will be described. The ballast loaded on the crushed stone carrier spreader 10 may be run by moving the crushed stone carrier spreader 10 and may be dispersed or may be stopped by stopping the crushed stone carrier spreader 10. Hereinafter, the ballast will be described with reference numeral 80.

  First, the case where the crushed stone transport spreader 10 travels and the ballast is sprayed will be described. The operator who got on the crushed stone transport / dispersion truck 10 operates the operation panel 30 or the operation panel 31 to drive either of the drive motors 24 and 25. For example, when traveling the crushed stone transport / dispersion truck 10 in the -Y direction, the operation panel 30 or the operation panel 31 is operated to drive the drive motor 24. The screw conveyor 22 is rotated in the K direction in FIG. 9 by the drive of the drive motor 24. Among the ballasts 80 loaded on the hopper frame 21, a part of the ballast 80 loaded on the lower part of the hopper frame 21 falls into the inside of the weir 53 by the weight of the ballast 80 itself. When the drive motor 23 is driven and the screw conveyor 22 rotates in the K direction in FIG. 9, the ballast 80 dropped to the weir 53 is pressed by the screw portion 22 a of the screw conveyor 22 and conveyed inside the weir 53. The ballast 80 transported to the inside of the weir 53 to the screw conveyor 22 falls into the track of the rail 17 from the discharge port 53 a.

  In the process of conveying the ballast 80 dropped to the weir 53 toward the discharge port 53 a by the rotation of the screw conveyor 22, the ballast 80 located near the opening 32 falls from the opening 32 into the weir 53. Therefore, when the screw conveyor 22 rotates, the ballast 80 loaded in the lower layer of the hopper frame 21 sequentially falls from the opening 32 into the inside of the weir 53 and is conveyed to the discharge port 53a by the rotating screw conveyor 22.

  As described above, in the XZ plane, the bending portion 45 a provided in the stabilizer 45 is offset from the rotation center of the screw conveyor 22 in the X direction. That is, among the ballasts 80 loaded on the hopper frame 21, the ballast 80 located in the vicinity of the stabilizer 45 is distributed to the side of the long piece 45 b of the stabilizer 45 by the stabilizer 45.

  The distance from the opening 32 to the tip of the long piece 45 b of the stabilizer 45 is set shorter than the distance from the opening 32 provided on the lower surface of the hopper frame 21 to the tip of the short piece 45 a of the stabilizer 45. Accordingly, the ballast 80 passing through the opening formed between the tip of the long piece 45 b of the stabilizer 45 and the side wall 21 b of the hopper frame 21 is between the tip of the short piece 45 a of the stabilizer 45 and the side wall 21 a of the hopper frame 21. The opening 32 is reached earlier than the ballast 80 passing through the opening formed in

  Here, the screw conveyor 22 rotates in the clockwise direction (K direction) in FIG. For example, when the position of the center of the opening 32 in the width direction coincides with the position of the rotation center of the screw conveyor 22, the position of the screw portion 22 a of the screw conveyor 22 is the highest position near the opening 32. Therefore, when the center position in the width direction of the opening 32 matches the position of the rotation center of the screw conveyor 22, the ballast 80 falling from the side wall 21a side of the hopper frame 21 to the opening 32 and the side wall 21b of the hopper frame 21 The ballast 80 falling from the side into the opening 32 tends to be repelled by the screw portion 22 a of the screw conveyor 22. Therefore, the amount of ballast 80 falling into the inside of the weir 53 varies. As a result, the dispersed amount of the ballast 80 sprayed in the track of the rail 17 also varies depending on the position where the crushed stone transport and scatterer 10 travels.

  In the present embodiment, the opening 32 is disposed in the XY plane with the position of the center in the width direction of the opening 32 being offset from the position of the rotation center of the screw conveyor 22 in the −X direction. When the position in the width direction of the opening 32 is shifted from the position of the rotation center of the screw conveyor 22, the ballast 80 falling from the side wall 21 b side of the hopper frame 21 is received by the screw portion 22 a of the rising screw conveyor 22. On the other hand, the ballast 80 falling from the side wall 21 a side of the hopper frame 21 tends to be repelled by the screw portion 22 a of the screw conveyor 22 moving downward. The screw portion 22 a of the screw conveyor 22 may press the ballast 80 dropped from the side wall 21 b of the hopper frame 21 while rotating it. Therefore, the ballast 80 falling from the side wall 21 a side of the hopper frame 21 collides with the ballast 80 pressed by the screw portion 22 a of the screw conveyor 22 and is repelled.

  As described above, in the present embodiment, the amount of passage of the ballast 80 passing through the opening portion formed between the long piece 45 b of the stabilizer 45 and the side wall 21 b of the hopper frame 21 is intentionally increased. The fall amount of the ballast 80 falling to the In other words, it is possible to suppress the variation in the transport amount of the ballast transported inside the weir 53 by the screw conveyor 22. As a result, it is possible to uniformly disperse the ballast 80 in the track of the rail 17.

  Further, when traveling the crushed stone transport / dispersion truck 10 in the Y direction, the drive motor 25 is driven to rotate the screw conveyor 23. It is the same as when screw conveyor 23 is rotated. That is, the passing amount of the ballast 80 passing through the opening portion formed between the tip of the long piece 46 b of the stabilizer 46 and the side wall 21 a of the hopper frame 21 is the tip of the short piece 46 a of the stabilizer 46 and the side wall 21 b of the hopper frame 21 The amount of drop of the ballast 80 falling to the weir 54 is adjusted by intentionally increasing the amount of passage of the ballast 80 passing through the opening portion formed between them. In other words, it is possible to suppress the variation in the transport amount of the ballast transported inside the weir 53 by the screw conveyor 23. As a result, even when the screw conveyor 23 is rotated, it is possible to uniformly disperse the ballast 80 within the track of the rail 17.

By the way, although the detail is omitted about the amount of dispersion of the ballast which is sprinkled from the running crushed stone transportation spreader 10, for example, the interval (pitch) of screw parts 22a and 23a of screw conveyors 22 and 23, and screw conveyors 22 and 23 And the traveling speed of the crushed stone transport and scatterer 10. As an example, the traveling speed of the crushed stone carrier spreader 10 is in the range of 0.5 to 10 km / h so that when the crushed stone carrier spreader 10 travels 100 m, the spread amount of the ballast 80 is 0.5 m ^{3 at} maximum. The rotational speed of the screw conveyor 22 is set in accordance with the traveling speed.

  In the present embodiment, either one of the two screw conveyors 22 and 23 is rotated according to the traveling direction of the crushed stone transportation / dispersing truck, but the screw conveyor of the two screw conveyors 22 and 23 is related Alternatively, it is also possible to rotate the two screw conveyors 22 and 23 simultaneously.

  When the ballast 80 is sprayed while traveling the quarry transport / dispersion truck 10, the camera 72 images the discharge port 53a of the weir 53 and the camera 73 images the discharge port 54a of the weir 54. The image information acquired by the cameras 72 and 73 is displayed on the monitor 30 a of the control panel 30 provided on the crushed stone transport / dispersion truck 10 or the monitor 31 a of the control panel 31, and is also displayed on the monitor 78 of the motor vehicle 11. . The spread state of the ballast 80 is detected by the spread amount detection sensor 74, and the detection result of the spread state of the ballast by the spread amount detection sensor 74 is displayed on each monitor. Therefore, an operator who drives the motor vehicle 11 can drive the motor vehicle 11 while checking an image displayed by the monitor 78 of the motor vehicle 11 and a detection result by the spread amount detection sensor 74, for example. Then, in the case where the dispersion of the ballast 80 into the track of the rail 17 is ended by the traveling crusher transporting scatterer 10, the operator operates the operation panel 30, 31 to stop the driving of the drive motor 24 or the drive motor 25. . The driving stop of the drive motor 23 stops the rotation of the screw conveyor 22 or the screw conveyor 23.

  When it is determined that the operator is abnormal in the image displayed by each monitor or the display of the detection result by the scattering amount detection sensor 74, the emergency stop button 79 provided on the motor vehicle 11 is operated. In addition, there is also a case where the driving of the drive motor 23 may be stopped while traveling on a section where the crushed stone transportation / dispersion truck 10 does not have to spray the ballast. In the case where the ballast is sprayed in the track of the rail 17 in the section where the ballast does not need to be sprayed, the worker operating the motor vehicle 11 operates the emergency stop button 79. When the emergency stop button 79 is operated, the control unit 70 stops the driving of the drive motor 23. Thereby, the rotation of the screw conveyor 22 or the screw conveyor 23 is stopped. As a result, the dispersion of the ballast 80 into the track of the rail 17 is completed.

  Thus, the state of the dispersion of the ballast 80 is imaged by the cameras 72 and 73, and the acquired image is observed. Further, the spread amount detection sensor 74 detects whether the ballast 80 to be spread is abnormally spread. At that time, if it is determined that there is an abnormality, the rotation of the screw conveyor 22 or the screw conveyor 23 can be stopped by operating the emergency stop button 79. In addition to this, it is also possible to judge whether or not the ballast 80 is clogged inside the weir 53 and the weir 54. As described above, the dispersion state of the ballast 80 can be appropriately determined from the image obtained by the cameras 72 and 73 and the detection result by the distribution amount detection sensor 74. Therefore, it is possible to appropriately perform the treatment based on the dispersion state of the ballast 80.

  Next, the case where the ballast 80 is sprayed out of the gauge of the rail 17 will be described. When the operator rotates, for example, the control lever 50 toward the outside of the crushed stone transport / dispersion truck 10, the shield plate 42 slides along the side wall 21b of the hopper frame 21 in the L direction in FIG. The discharge port 40 is opened by the slide of the shield plate 42, and the ballast 80 loaded inside the hopper frame 21 falls through the discharge port 40. The ballast 80 dropped from the discharge port 40 moves along the chute 63. Here, the tip of the chute 63 is located outside the rail 17 of the rail 17. Therefore, the ballast 80 moved to the tip of the chute 63 is sprayed out of the track 17 of the rail 17.

  Then, when the spray amount of the ballast 80 sprayed outside the rail 17 of the rail 17 becomes the target spray amount, the operator rotates the operation lever 50 to the center side of the crushed stone transport / scattering wheel 10. Thus, the shielding plate 42 slides in the M direction in FIG. 10 along the side wall 21 b of the hopper frame 21. The slide of the shield plate 42 shields the discharge port 40. As the discharge port 40 is shielded by the shielding plate 42, the ballast 80 loaded on the hopper frame 21 is stopped from falling from the discharge port 40. That is, the spraying of the rail 17 out of the gauge ends. The same applies to the case where any one of the control levers 49, 51, 52 is rotated.

  Thus, by operating the control levers 49, 50, 51, 52 of the crushed stone transport / dispersion wheel 10, the ballast 80 can be dispersed outside the gauge of the rail 17. When adjusting the amount of dispersion of the ballast 80, the amount of operation of the operating lever to be rotated may be adjusted to adjust the amount of opening of the discharge port.

  In this embodiment, the case where two screw conveyors 22 are arranged such that the rotation axes thereof are parallel to the extending direction of the rails and the rotation axes of the respective conveyors are coaxial is described. It is not necessary to use a screw conveyor 22, and it is possible to implement the invention even if one screw conveyor 22 is arranged. In addition to arranging the two screw conveyors 22 and 23 so that their rotational axes are coaxial, it is also possible to align the two screw conveyors 22 and 23 in the rail extension direction.
