  For example, a crushed stone carrying and scattering vehicle that rotates a side wall of a loading platform by a predetermined amount can disperse ballast in a rail gauge by rotating a side wall orthogonal to the traveling direction of the vehicle by a predetermined amount. However, since ballast may be sprayed on the rail, it is necessary for an operator to work while visually confirming the ballast spraying state. On the other hand, when the side wall along the traveling direction of the vehicle is rotated among the side walls of the loading platform, the ballast is not placed on the rail because the ballast is scattered outside the rail between the rails. Therefore, it is necessary to stir the ballast dispersed outside the rail gauge into the rail gauge.

By providing the stabilizer 28 in the hopper frame 21 and in the vicinity of the upper part of the openings 21c and 21c, the ballast that reaches the stabilizer 28 moves toward the side wall 21d or the inclined surface 21e. That is, by providing the stabilizer 35, the ballast concentrates in each of the openings 21b and 21c, and the ballast is prevented from being clogged in the vicinity of the openings 21b and 21c.

  Two rectangular openings 29a and 29b are formed on the side wall 21d of the hopper frame 21 and in the vicinity of the opening 21b and the opening 21c. These openings 29 a and 29 b are arranged along the extending direction of the rail 17. These openings 29a and 29b are shielded by the shielding plate 31, respectively.

  Similarly, two rectangular openings 30a and 30b are formed on the side wall 21e of the hopper frame 21 and in the vicinity of the opening 21b and the opening 21c. These openings 30 a and 30 b are arranged along the extending direction of the rail 17. The openings 30a and 30b are shielded by the shielding plate 32, respectively.

  The shielding plate 31 slides between a position where the openings 29a and 29b are shielded and a position where the openings 29a and 29b are opened. The shielding plate 31 is connected to the operation lever 33 via a connection mechanism (not shown). The shielding plate 32 slides between a position where the openings 30a and 30b are shielded and a position where the openings 30a and 30b are opened. The shielding plate 32 is connected to the operation lever 34 via a connection mechanism (not shown).

  The operation lever 33 is provided to be rotatable between a position indicated by a solid line in FIG. 5 and a position indicated by a two-dot chain line in FIG. When the operation lever 33 is held at the position shown by the solid line in FIG. 5, the openings 29 a and 29 b are shielded by the shielding plate 31. When the operation lever 33 is held at the position indicated by the two-dot chain line in FIG. 5, the openings 29a and 29b are opened.

  Similarly, the operation lever 34 is provided to be rotatable between a position indicated by a solid line in FIG. 5 and a position indicated by a two-dot chain line in FIG. When the operation lever 34 is held at the position indicated by the solid line in FIG. 5, the openings 30 a and 30 b are shielded by the shielding plate 32. When the operation lever 34 is held at the position indicated by the two-dot chain line in FIG. 5, the openings 30a and 30b are opened.

  Below the openings 21 b and 21 c provided in the hopper frame 21, hooks 35 and 36 are provided along the extending direction of the rail 17. Screw conveyors 22a and 22b are arranged inside the cages 35 and 36, respectively. The screw conveyors 22a and 22b are arranged so that the respective rotation axes are along the extending direction of the rail 17 and the respective rotation axes are coaxial. Here, the position of the rotating shaft of the screw conveyors 22a and 22b is the same position as the center position of the crushed stone transporting and dispersing vehicle 10 in the X direction. In addition, in FIG. 5, the symbol C is attached | subjected and demonstrated with respect to the rotating shaft of a screw conveyor. These screw conveyors 22a and 22b are arranged so that the upper parts thereof enter the inside of the hopper frame 21 through the openings 21b and 21c, respectively.

  The screw conveyor 22a is connected to the motor 23a via a drive mechanism 53a including, for example, a drive chain and a sprocket. When the screw conveyor 23a rotates, the ballast that has fallen on the flange 35 is pressed against the screw portion of the rotating screw conveyor 23a. By this pressing, the ballast is transported toward the discharge port 35a formed in the flange 35. Similarly, the screw conveyor 22b is connected to the motor 23b via a drive mechanism 53b composed of, for example, a drive chain and a sprocket. When the screw conveyor 23b is rotated, the ballast that has fallen on the flange 36 is pressed against the screw portion of the rotating screw conveyor 23b. By this pressing, the ballast is transported toward the discharge port 36a formed in the flange 36. Examples of the motors 23a and 23b that rotate the screw conveyors 22a and 22b include an electric motor and a hydraulic pump motor. Here, the positions of the discharge ports 35 a and 36 a formed in the flanges 35 and 36 in the X direction are within the rails of the rail 17. Therefore, the ballast dropped from the discharge ports 35 a and 36 a is dispersed in the rail 17. In addition, these discharge ports 35a and 36a may always be opened, or may be shielded by a lid member that is opened when ballast is sprayed.

  A chute 24 is provided below the openings 29 a and 29 b formed in the side surface 21 d of the hopper frame 21. A chute 25 is provided below the openings 30a and 30b formed in the side surface 21e of the hopper frame 21. These chutes 24 and 25 are formed from a steel plate. These chutes 24 and 25 are arranged so as to incline downward from the center of the load receiving frame 20 toward the outside of the load receiving frame 20 in the X direction. By arranging such chutes 24 and 25, the ballast falling from the openings 29a and 29b and the openings 30a and 30b moves along the chutes 24 and 25, and from the tips of the chutes 24 and 25 to the outside of the rail 17 Fall.

  The cameras 45a and 45b are disposed in the vicinity of the outlets 35a and 36a of the ridges 35 and 36, respectively. These cameras 45a and 45b image the insides of the discharge ports 35a and 36a and the rail 17. Images captured by these cameras 45 a and 45 b are displayed on a monitor 52 provided on the motor vehicle 11 in addition to being displayed on a monitor 52 provided on the crushed stone transporting and scattering vehicle 10.

  FIG. 6 is a diagram showing an electrical configuration when signals are transmitted and received between the crushed stone transporting and scattering vehicle 10 and the motor vehicle 11. FIG. 6 shows a case where one crushed stone transporting and scattering vehicle 10 is connected to the motor vehicle 11. Moreover, in FIG. 6, about the motor vehicle 11, the structure which communicates with the crushed stone conveyance scattering vehicle 10 is described, and it abbreviate | omits about another structure.

  The crushed stone transporting and dispersing vehicle 10 includes a control unit 50, a communication unit 51, a monitor 52, cameras 45a and 45b, motors 23a and 23b, drive mechanisms 53a and 53b, screw conveyors 22a and 22b, an operation panel 54, and the like.

  The control unit 50 receives an operation signal from the operation panel 54 and performs communication control with the motor vehicle in addition to drive control of the motors 23 a and 23 b mounted on the crushed stone transporting and scattering vehicle 10 and display control of the monitor 52. Do. The communication unit 51 performs wireless communication with the motor vehicle 11 to transmit and receive signals. In addition, as a signal, signals, such as a control command, are mentioned besides the video signal acquired by the cameras 45a and 45b. The monitor 52 displays an image for assisting the operation on the operation panel 54 in addition to displaying an image based on the image signal acquired by the cameras 45a and 45b. The operation panel 54 includes a plurality of operation buttons including a button for driving the motors 23a and 23b and a button for stopping the driving of the motors 23a and 23b.

  The motor vehicle 11 includes a control unit 56, a communication unit 57, a monitor 58, and an emergency stop button 59. The control unit 56 receives each operation signal from an operation panel (not shown) and controls each unit of the motor vehicle 11. The communication unit 57 performs wireless communication with the crushed stone transporting and scattering vehicle 11. With this wireless communication, it is possible to receive video signals from the cameras 45 a and 45 b installed in the crushed stone transporting and scattering vehicle 10 and transmit an emergency stop signal from the emergency stop button 59 toward the crushed stone transporting and scattering vehicle 11. Become. The monitor 58 displays an image based on the image signal transmitted from the crushed stone transporting and scattering vehicle 10. The emergency stop button 59 is operated when the motors 23a and 23b are stopped when it is determined that the sprayed state of the ballast to be sprayed is poor. When the emergency stop button 59 is operated, the control unit 56 transmits an emergency stop signal toward the crushed stone transporting and scattering vehicle 10.

  In addition, in FIG. 6, the structure in the case of transmitting / receiving the signal between the one crushed stone conveyance scattering vehicle 10 and the motor vehicle 11 is represented. However, in the crushed stone spraying operation, the motor vehicle 11 is generally connected to 2 to 4 crushed stone transporting and scattering vehicles 10. Therefore, about the wireless communication performed between each crushed stone conveyance scattering vehicle, you may perform using a different communication channel with each vehicle, and may perform using a common communication channel.

  Hereinafter, the operation of the crushed stone carrying and scattering vehicle when spraying the loaded ballast will be described. The ballast loaded on the crushed stone transporting and scattering vehicle 10 may be sprayed by running the crushed stone transporting and scattering vehicle 10 or may be sprayed by stopping the crushed stone transporting and scattering vehicle 10. Hereinafter, the ballast will be described with reference numeral 70.

  First, the case where the crushed stone transporting and scattering vehicle 10 is run to spray the ballast 70 will be described. In this case, the worker who rides on the crushed stone transporting and scattering vehicle 10 operates the operation panel 54 to drive one of the motors 23a and 23b. For example, when the crushed stone transporting and scattering vehicle 10 travels in the -Y direction, the motor 23a is driven. The screw conveyor 22a rotates in the direction D by driving the motor 23a. The ballast 70 that has fallen on the flange 35 is pressed by the rotation of the screw conveyor 22a, and is conveyed toward the discharge port 35a (in the -Y direction). And the ballast 70 conveyed to the discharge port 35a falls from the discharge port 35a. When the ballast 70 is conveyed by the screw conveyor 22a, the ballast 70 loaded on the lower layer of the hopper frame 21 falls from the opening 21b to the flange 35. Therefore, while the screw conveyor 22a is rotating, the ballast 70 placed in the hopper frame 21 is sprayed in order from the ballast 70 in the lower layer. Here, since the position of the discharge port 35a in the X direction is located in the gauge of the rail 17, the ballast 70 falling from the discharge port 35a is moved into the gauge of the rail 17 from the traveling crushed stone transporting and scattering vehicle 10. And it is sprayed along the rail 17.

  When the ballast 70 is dispersed, the vicinity of the discharge port 35a is imaged by the camera 45a. At the same time, the scattering state of the ballast 70 dispersed in the space between the rails 17 is imaged by the camera 45b. The video information acquired by these cameras 45a and 45b is displayed on the monitor 58 of the motor vehicle 11 in addition to being displayed on the monitor 52 provided in the crushed stone transporting and scattering vehicle 10. Therefore, the operator who drives the motor vehicle 11 can drive the motor vehicle 11 while observing the image displayed on the monitor 58.

  Then, when the traveling of the crushed stone transporting and scattering vehicle 10 ends the application of the ballast 70 along the rail 17, the operator operates the operation panel 54 to stop the driving of the motor 23a. The rotation of the screw conveyor 22a is stopped by stopping the driving of the motor 23a. Therefore, the ballast 70 that has fallen on the cage 35 is held inside the cage 35 without being conveyed by the screw conveyor 22a.

  Here, during the traveling of the crushed stone transporting and scattering vehicle 10, the ballast 70 is applied to a section where the application state of the ballast 70 applied to the rails between the rails 17 is not good or to the section where the ballast 70 does not need to be applied. There may be. In such a case, the operator who drives the motor vehicle 11 operates the emergency stop button 59. When the emergency stop button 59 is operated, the control unit 56 transmits an emergency stop signal to the crushed stone transporting and scattering vehicle 10 via the communication unit 57. This emergency stop signal is received by the communication unit 51 of the crushed stone transporting vehicle 10. When the emergency stop signal is received, the control unit 50 stops driving the motor 23a. Thereby, rotation of screw conveyor 22a is stopped. As a result, the application of the ballast 70 within the rails of the rail 17 is completed.

  As described above, the state of the ballast 70 spraying and the state of the ballast 70 spraying within the gauge of the rail 17 are acquired by the cameras 45a and 45b, and the acquired image is observed, whereby the ballast 70 spraying is abnormal. It can be determined whether or not. If it can be determined that there is an abnormality at that time, the rotation of the screw conveyor 22a can be stopped by operating the emergency stop button 59. Further, by observing the state in which the ballast falls from the discharge port 35a, it can also be determined whether or not the ballast 70 is clogged inside the rod 35. As described above, it is possible to appropriately determine the dispersion state of the ballast 70 from the images obtained by the cameras 45a and 45b, and it is possible to appropriately perform a treatment based on the determination.

  Here, when the crushed stone transporting and scattering vehicle 10 travels in the Y direction, the motor 23b is driven. That is, the screw conveyor 22b rotates, and the ballast 70 conveyed through the inside of the cage 36 by the screw conveyor 22b is sprayed into the rail 17 from the discharge port 36a.

By the way, the amount of application of the ballast 70 sprayed from the traveling crushed stone transporting and scattering vehicle 10 depends on the screw interval (pitch) of the screw conveyors 22a and 22b, the rotational speed of the screw conveyors 22a and 22b, and the traveling of the crushed stone transporting and scattering vehicle 10. It can be determined from the speed. As an example, the rotation speed of the screw conveyors 22a and 22b and the traveling speed of the crushed stone transporting scatter vehicle are set so that when the crushed stone transporting truck 10 travels 100 m, the spray amount of the ballast 70 is 0.5 m ^{3 at the} maximum. Is done.

  Next, the case where the crushed stone transporting and scattering vehicle 10 is stopped and the ballast 70 is sprayed will be described. In this case, the operator rotates the operation lever 33 in the direction F in FIG. As the operation lever 33 rotates, the shielding plate 31 slides in the direction G in FIG. The sliding movement of the shielding plate 31 opens the openings 29a and 29b. By opening the openings 29a and 29b, the ballast 70 loaded inside the hopper frame 21 falls through the openings 29a and 29b.

  Here, the ballast 70 dropped from the openings 29 a and 29 b moves along the chute 24. Then, the ballast 70 that has moved to the tip of the chute 24 falls. Here, the position of the tip of the chute 24 in the X direction is located outside the gauge of the rail 17. Therefore, the ballast 70 that falls from the tip of the chute 24 is scattered outside the rail 17.

  When the sprayed amount of the ballast 70 to be sprayed becomes the target sprayed amount, the operator rotates the operation lever 33 in the H direction in FIG. As a result, the shielding plate 31 slides in the direction I in FIG. 8, and the openings 29a and 29b are shielded. Since the openings 29a and 29b are shielded by the shielding plate 31, the ballast 70 crushed by the hopper frame 21 is stopped from falling from the openings 29a and 29b. That is, the application of the ballast 70 to the outside of the rail 17 is completed.

  The same applies when the operation lever 34 is rotated in the J direction in FIG. That is, when the operation lever 34 is rotated in the J direction in FIG. 3, the shielding plate 32 slides in the K direction in FIG. 7, and the openings 30a and 30b are opened. Therefore, the ballast 70 falls from the openings 30a and 30b. Then, the dropped ballast 70 moves along the chute 25 and is spread out of the rail 17. Also in this case, when the operation lever 34 is rotated in the L direction in FIG. 3, the shielding plate 32 slides in the M direction in FIG. By this sliding movement, the openings 30a and 30b are shielded, and the application of the ballast 70 is completed.

  Thus, when the ballast 70 which stopped the loading conveyance scattering vehicle 10 is sprayed, it becomes possible to spray the ballast 70 outside the gauge of the rail 17.

  In addition, when adjusting the spreading | diffusion amount of the ballast 70, what is necessary is just to adjust the opening amount of opening 29a, 29b and opening 30a, 30b by adjusting the operation amount of the operation levers 33 and 34, respectively.

  In the embodiment described above, the openings 29a and 29b are opened by sliding the shielding plate 31, or the openings 29a and 29b are shielded. Similarly, the openings 30a and 30b are opened by sliding the shielding plate 32, or the openings 30a and 30b are shielded. Here, when the shielding plate 31 is slid to shield the openings 29a and 29b, or when the shielding plate 32 is slid to shield the openings 30a and 30b, the ballast 70 falling from the respective openings is the shielding plate. There is a case where it is pinched (biting) between the edges of the opening. In such a case, the opening is not completely shielded. When the crushed stone carrying and scattering vehicle 11 is run in such a state, the ballast 70 may fall from the gap between the edge of the opening and the shielding plate generated by biting the ballast 70, which is dangerous.

  Therefore, it is also possible to provide the fall prevention plates 75 and 76 outside the shielding plate 31 and the shielding plate 32, respectively. In this case, the fall prevention plates 75 and 76 are provided to be rotatable with respect to the chutes 24 and 25, respectively.

  For example, the rotation of the fall prevention plate 75 and the sliding movement of the shielding plate 31 are performed as follows. For example, when opening the openings 29a and 29b, the fall prevention plate 75 is first rotated from the position shown in FIG. 9 to the position shown in FIG. Thereafter, the shielding plate 31 is slid to open the openings 29a and 29b. Further, when shielding the openings 29a and 29b, after sliding the shielding plate 31 to shield the openings 29a and 29b, the fall prevention plate 75 is rotated from the position shown in FIG. 10 to the position shown in FIG. Let

  Here, the rotation of the fall prevention plate 76 is the same as that of the fall prevention plate 75. That is, when opening the openings 30a and 30b, the fall prevention plate 76 is first rotated to the position shown in FIG. Thereafter, the shielding plate 32 is slid to open the openings 30a and 30b. On the other hand, when shielding the openings 30a and 30b, the shielding plate 32 is slid to shield the openings 30a and 30b. Thereafter, the fall prevention plate 76 is rotated from the position shown in FIG. 10 to the position shown in FIG.
