The load receiving stand 16 is detachably attached to the material transport vehicles 15a and 15b. As is well known, the material transport vehicles 15a and 15b are vehicles used when conveying materials such as rails. In the present invention, the crushed stone transporting and scattering vehicle 10 is composed of the material transport vehicles 15a and 15b and the load receiving table 16, and the load receiving table 16 is detachable from the material transport vehicles 15a and 15b. Alternatively, the crushed stone carrying and scattering vehicle 10 in which a wheel unit including wheels, an axle, and the like is integrally assembled to the load receiving table 16 may be used. Reference numeral 17 denotes a rail for driving the material transport vehicles 15a and 15b.

  The hopper frame 21 is loaded with crushed stone (ballast) to be distributed in and out of the rail 17. Here, the ballast has a size of about 100 mm in diameter, for example. The hopper frame 21 is formed by welding a plurality of steel plates. The hopper frame 21 has a cylindrical shape in which the upper surface is opened and the cross-sectional area of the XY plane decreases from the upper surface to the lower surface. Two openings 32 and 33 along the longitudinal direction (Y direction) are provided on the lower surface of the hopper frame 21. The openings 32 and 33 allow the ballast loaded on the hopper frame 21 to drop into a cage provided below the hopper frame 21. Among the openings 32 and 33, the opening 32 is provided at a position where the center in the short direction is shifted to the left side in FIG. 4 from the center of the screw conveyor 22 (or the center in the width direction of the hopper frame 21). Further, the opening 33 is provided at a position where the center in the short direction is shifted to the right side in FIG. 4 from the center of the screw conveyor 23 (or the center in the width direction of the hopper frame 21). In FIG. 4, the symbol S is attached to the center of the hopper frame 21 in the width direction.

  The side walls 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. Thereby, the ballast located in the vicinity of the side walls 21a and 21b of the hopper frame 21 moves toward the openings 32 and 33. Further, 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 either the opening 32 or the opening 33 of the ballast that moves inside the hopper frame 21. It is a member for distributing to one of the openings.

  The side wall 21 a of the hopper frame 21 has a discharge port 36 in the vicinity of the opening 32 and a discharge port 37 in the vicinity of the opening 33. As described above, the discharge port 36 is provided along the opening 32, and the discharge port 37 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 36 and the discharge port 37 are each divided into, for example, four pieces by the reinforcing material 34. The discharge port 36 is covered with a shielding plate 38, and the discharge port 37 is covered with a shielding plate 39.

  Similarly, the side wall 21 b of the hopper frame 21 has a discharge port 40 near the opening 32 and a discharge port 41 near the opening 33. As described above, the discharge port 40 is provided along the opening 32, and the discharge port 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, for example, four pieces by the reinforcing material 34. The discharge port 40 is covered with a shielding plate 42, and the discharge port 41 is covered with a shielding plate 43.

  The hopper frame 21 includes stabilizers 45 and 46. The stabilizer 45 is disposed in the vicinity of the upper portion of the opening 32, and the stabilizer 46 is disposed in the vicinity of the upper portion 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 direction. In the stabilizer 45, the gap D between the tip of the short piece 45a and the side wall 21a of the hopper frame 21 in the XZ plane and the gap E between the tip of the long piece 45b and the side wall 21b of the hopper frame 21 in the XZ plane are the same gap (D = E) is arranged above the opening 32. 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. When the stabilizer 45 is disposed on the hopper frame 21, the position in the X direction of the bent portion (hereinafter, the bent portion 45 c) is shifted to the right side (X direction) from the center in the width direction of the hopper frame 21. Position.

  Similarly, in the stabilizer 46, the gap F between the tip of the short piece 46a and the side wall 21b of the hopper frame 21 in the XZ plane is the same as the gap G between the tip of the long piece 46b and the side wall 21a of the hopper frame 21 in the XZ plane. Is arranged above the opening 33 so as to be a gap (F = G). That is, the area of the opening provided between the tip of the short piece 46 a of the stabilizer 46 and the side wall 21 b of the hopper frame 21, and the opening of the opening provided between the long piece 46 b of the stabilizer 46 and the side wall 21 a of the hopper frame 21. The area is set to the same area. When the stabilizer 46 is disposed on the hopper frame 21, the position of the bent portion (hereinafter, the bent portion 46 c) in the X direction is shifted from the center in the width direction of the hopper frame 21 to the right side (−X direction). It becomes the position.

  Here, the gaps D and E generated between the stabilizer 45 and the side walls 21a and 21b of the hopper frame 21 and the gaps F and G between the stabilizer 46 and the side walls 21a and 21b of the hopper frame 21 are the ballast 1 having an average size. It is set to about one or two diameters.

  By providing the stabilizers 45 and 46 in the hopper frame 21, the ballast that has reached the position of the stabilizers 45 and 46 is distributed to the side wall 21a or the side wall 21b of the hopper frame 21 by the slopes of the stabilizers 45 and 46, respectively. It is done. As a result, among the ballasts loaded on the hopper frame 21, it is possible to prevent the ballast in the lower layer from concentrating on the openings 32 and 33 and clogging the ballast in the vicinity of the openings 32 and 33.

  As shown in FIG. 4, in the top view of the crushed stone transporting and dispersing vehicle 10, in the structure inside the hopper frame 21, the positional relationship between the opening 32 and the opening 33 when the center P of the crushed stone transporting and scattering vehicle 10 is used as a reference. 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 respect to a straight line Q passing through the center P of the crushed stone transporting and scattering vehicle 10.

  4, the screw conveyors 22 and 23 and the openings 32 and 33 are hidden by the stabilizers 45 and 46 and the hopper frame, but for the sake of convenience, a two-dot chain line and the opening 32 are provided. , 33 using dotted lines.

  The operation levers 48, 49, 50, 51 are provided in correspondence with the four shielding plates 38, 39, 42, 43 described above. For example, the operation lever 48 has a state where one end to be operated is inclined toward the center in the width direction of the crushed stone transporting scatter vehicle 10 (position shown by a solid line in FIG. 3), and the one end is the width of the crushed stone transport scatter vehicle 10. It is provided so as to be rotatable between a state inclined toward the outside in the direction (a position indicated by a two-dot chain line in FIG. 3). When the operation lever 48 is held at the position indicated by the solid line in FIG. 3, the discharge port 36 is shielded by the shielding plate 38. When the operation lever 48 is operated from the position indicated by the solid line in FIG. 3 to the position indicated by the two-dot chain line in FIG. 3, the shielding plate 38 slides to open the discharge port 36.

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

  Below the openings 32 and 33 provided in the hopper frame 21, flanges 53 and 54 are provided along the longitudinal direction (Y direction) of the hopper frame 21. Screw conveyors 22 and 23 are arranged inside the eaves 53 and 54, respectively.

Here, the screw conveyors 22, 23 are arranged at the center of the rotation axis in the width direction (X direction) of the crushed stone transporting scattering vehicle 10.

  The screw conveyor 22 is connected to a drive motor 24 via a drive mechanism including, 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 that has fallen on the flange 53 is pressed against the screw portion 22a of the screw conveyor 22 that rotates. As a result, the ballast is conveyed by the screw conveyor 22 toward the discharge port 53a through the inside of the flange 53 and then falls from the discharge port 53a into the rail 17. In addition, the discharge port 53a provided in the bag 53 may be always opened, or may be opened / closed by main movement or automatically.

  Similarly, the screw conveyor 23 is connected to the drive motor 25 via a drive mechanism including, 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 on the flange 54 is pressed by the screw portion 23a of the screw conveyor 23 that rotates. As a result, the ballast is transported by the screw conveyor 23 toward the discharge port 54a through the inside of the flange 54, and then falls from the discharge port 54a into the rail 17 rail. In addition, the discharge port 54a provided in the eaves 54 may be always opened, or may be opened or closed by main movement or automatically.

  Chutes 61 and 62 are provided below the discharge ports 36 and 37 in the side wall 21a of the hopper frame 21. Chutes 63 and 64 are provided below the discharge port 40 and the discharge port 41 in the side wall 21 b of the hopper frame 21. The chutes 61, 62, 63, 64 are formed from a steel plate. The chutes 61, 62, 63, 64 are respectively 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. Are arranged as follows. By arranging such chutes 61, 62, 63, 64, the ballast falling from the discharge ports 36, 37, 40, 41 moves along the chutes 61, 62, 63, 64, and then the chutes 61, 62. , 63, 64 from the tip of the rail 17 falls outside the gauge.

  The operation panels 30 and 31 have a plurality of operation buttons including a button for driving the drive motor 23 and a button for stopping the drive motor 23. The operation panels 30 and 31 include monitors 30a and 31a that display images captured by cameras 72 and 73, which will be described later, and images that assist operations on a plurality of operation buttons.

  FIG. 8 is a diagram illustrating an electrical configuration when signals are transmitted and received between the crushed stone transporting and scattering vehicle 10 and the motor vehicle 11. FIG. 8 shows a case where one crushed stone transporting and scattering vehicle 10 is connected to the motor vehicle 11. Moreover, in FIG. 8, the structure of the motor vehicle 11 has described only the structure which communicates with the crushed stone conveyance scattering vehicle 10. FIG.

  The crushed stone carrying and scattering vehicle 10 includes a control unit 70, a communication unit 71, cameras 72 and 73, a spray amount detection sensor 74, and the like, in addition to the operation panels 30 and 31 described above. The control unit 70 receives an operation signal from the operation panels 30 and 31, and controls the drive motors 24 and 25 mounted on the crushed stone transporting and scattering vehicle 10 and displays the monitors 30 a and 31 a provided on the operation panels 30 and 31. In addition to 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. Note that examples of the signal include a video command signal acquired by the cameras 72 and 73 and a signal such as a control command.

  The camera 72 is disposed in the vicinity of the discharge port 53a of the bag 53, and the camera 73 is disposed in the vicinity of the discharge port 54a of the bag 54. The cameras 72 and 73 capture an image (moving image or still image) with the discharge ports 53a and 54a as an imaging range. Images captured by the cameras 72 and 73 are displayed on the monitor 30 a of the operation panel 30 or the monitor 31 a of the operation panel 31 and the monitor 78 provided in the motor vehicle 11.

  The motor vehicle 11 includes a control unit 76, a communication unit 77, a monitor 78, an emergency stop button 79, and the like. The control unit 77 receives each operation signal from an operation panel (not shown) and controls each unit of the motor vehicle 11. The communication unit 78 performs wireless communication with the crushed stone transporting and scattering vehicle 10. With this wireless communication, it is possible to receive video signals from the cameras 72 and 73 installed in the crushed stone transporting and scattering vehicle 10 and transmit an emergency stop signal from the emergency stop button 79 to the crushed stone transporting and scattering vehicle 10. Become. The monitor 78 displays an image based on the image signal transmitted from the crushed stone transporting and scattering vehicle 10. The emergency stop button 79 is operated when the drive motors 24 and 25 are stopped when it is determined that the sprayed state of the ballast to be sprayed is poor. When the emergency stop button is operated, the control unit transmits an emergency stop signal toward the crushed stone transporting vehicle 10.

  In addition, in FIG. 8, although the structure in the case of transmitting / receiving the signal between the one crushed stone conveyance scattering vehicle 10 and the motor vehicle 11, the motor vehicle 11 is 2-4 in the crushed stone scattering work. It is common to be connected with the crushed stone carrier dispersion car 10 of a stand. Therefore, the wireless communication performed with each crushed stone carrying and scattering vehicle 10 is executed using a different communication channel for each vehicle.

  Hereinafter, the operation of the crushed stone carrying and scattering vehicle 10 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 80.

  First, the case where the crushed stone transporting and scattering vehicle 10 is run to spray ballast will be described. An operator who rides on the crushed stone carrying and scattering vehicle 10 operates the operation panel 30 or the operation panel 31 to drive one of the drive motors 24 and 25. For example, when the crushed stone transporting and scattering vehicle 10 travels in the −Y direction, the operation motor 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. Of the ballast 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 cage 53 due to its own weight. When the drive motor 23 is driven and the screw conveyor 22 rotates in the K direction in FIG. 9, the ballast 80 that has fallen on the flange 53 is pressed by the screw portion 22 a of the screw conveyor 22 and is conveyed through the interior of the flange 53. The ballast 80 conveyed through the inside of the flange 53 to the screw conveyor 22 falls into the rails of the rail 17 from the discharge port 53a.

  In the process in which the ballast 80 that has fallen on the flange 53 is conveyed toward the discharge port 53 a by the rotation of the screw conveyor 22, the ballast 80 located in the vicinity of the opening 32 falls from the opening 32 to the inside of the flange 53. Therefore, when the screw conveyor 22 is rotated, the ballast 80 stacked in the lower layer of the hopper frame 21 is dropped from the opening 32 to the inside of the eave 53, and is conveyed to the discharge port 53a by the rotating screw conveyor 22.

  As described above, in the XZ plane, the bent portion 45 a provided in the stabilizer 45 is shifted 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 near the stabilizer 45 is distributed by the stabilizer 45 to the long piece 45 b side of the stabilizer 45.

  The distance from the opening 32 to the tip of the long piece 45b 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 45a of the stabilizer 45. Therefore, the ballast 80 passing through the opening formed between the tip of the long piece 45b of the stabilizer 45 and the side wall 21b of the hopper frame 21 is between the tip of the short piece 45a of the stabilizer 45 and the side wall 21a of the hopper frame 21. The opening 32 is reached at a timing earlier than that of the ballast 80 that passes through the opening portion formed at the front.

  Here, the screw conveyor 22 is rotating clockwise in FIG. 9 (K direction). For example, when the position of the center of the opening 32 in the width direction matches 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 in the vicinity of the opening 32. Therefore, when the position of the center in the width direction of the opening 32 and the position of the rotation center of the screw conveyor 22 are matched, the ballast 80 that falls from the side wall 21 a side of the hopper frame 21 to the opening 32 and the side wall 21 b of the hopper frame 21. The ballast 80 falling from the side to the opening 32 is likely to be struck by the screw portion 22 a of the screw conveyor 22. Therefore, variation occurs in the amount of ballast 80 that falls into the cage 53. As a result, an event occurs in which the amount of ballast 80 sprayed in the rail 17 varies depending on the position where the crushed stone transporting vehicle 10 travels.

  In the present embodiment, the opening 32 is arranged by shifting the position of the center in the width direction of the opening 32 in the −X direction with respect to the position of the rotation center of the screw conveyor 22 on the XY plane. 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 21a side of the hopper frame 21 is easily struck by the screw portion 22a of the screw conveyor 22 that descends. Moreover, the screw part 22a of the screw conveyor 22 may be pressing while rotating the ballast 80 dropped from the side wall 21b side of the hopper frame 21. 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 bounced.

  As described above, in the present embodiment, the amount of the ballast 80 passing through the opening formed between the long piece 45b of the stabilizer 45 and the side wall 21b of the hopper frame 21 is intentionally increased, so that The amount of fall of the ballast 80 that falls is adjusted. That is, it is possible to suppress variation in the amount of ballast transported inside the ridge 53 by the screw conveyor 22. As a result, it is possible to uniformly disperse the ballast 80 in the space between the rails 17.

  Moreover, when driving the crushed stone transporting and scattering vehicle 10 in the Y direction, the drive motor 25 is driven to rotate the screw conveyor 23. This is the same as when the screw conveyor 23 is rotated. That is, the passing amount of the ballast 80 passing through the opening formed between the tip of the long piece 46b of the stabilizer 46 and the side wall 21a of the hopper frame 21 is determined by the amount of passage of the ballast 80 passing through the opening portion formed between the side wall 21b of the hopper frame 21. The amount of ballast 80 falling on the flange 54 is adjusted by intentionally increasing the amount of ballast 80 passing through the opening formed between the two. That is, it is possible to suppress variation in the amount of ballast transported inside the ridge 53 by the screw conveyor 23. As a result, even when the screw conveyor 23 is rotated, the ballast 80 can be uniformly dispersed in the rails of the rails 17.

By the way, although the detail is abbreviate | omitted about the spreading | diffusion amount of the ballast spread | dispersed from the crushed stone conveyance spreading vehicle 10 to drive, for example, the space | interval (pitch) of the screw parts 22a and 23a of the screw conveyors 22 and 23, or the screw conveyors 22 and 23. And the traveling speed of the crushed stone transporting and scattering vehicle 10 can be obtained. As an example, when the crushed stone transporting vehicle 10 travels 100 meters, the traveling speed of the crushed stone transporting vehicle 10 is in the range of 0.5 to 10 km / h so that the amount of sprayed ballast 80 is 0.5 m ^{3 at the} maximum. Thus, the rotational speed of the screw conveyor 22 is set in accordance with the traveling speed.

  In this embodiment, one of the two screw conveyors 22 and 23 is rotated in accordance with the traveling direction of the crushed stone transporting and scattering vehicle. It is also possible to rotate the two screw conveyors 22, 23 simultaneously.

  When the ballast 80 is sprayed while the quarrying and transporting vehicle 10 is traveling, the camera 72 images the discharge port 53a of the basket 53, and the camera 73 images the discharge port 54a of the basket 54. The video information acquired by the cameras 72 and 73 is displayed on the monitor 30a of the operation panel 30 or the monitor 31a of the operation panel 31 provided in the crushed stone transporting and scattering vehicle 10, and also displayed on the monitor 78 of the motor vehicle 11. . Further, the spraying state of the ballast 80 is detected by the spraying amount detection sensor 74, and the detection result of the ballast spraying state by the spraying amount detection sensor 74 is displayed on each monitor. Therefore, the operator who drives the motor vehicle 11 can drive the motor vehicle 11 while confirming, for example, the image displayed on the monitor 78 of the motor vehicle 11 and the detection result by the scattering amount detection sensor 74. When the traveling of the crushed stone transporting and scattering vehicle 10 ends the application of the ballast 80 into the rails of the rail 17, the operator operates the operation panels 30 and 31 to stop the driving motor 24 or the driving motor 25 from being driven. . When the drive motor 23 is stopped, the rotation of the screw conveyor 22 or the screw conveyor 23 is stopped.

  If the operator can determine that there is an abnormality in the images displayed by the monitors and the detection result display by the spray amount detection sensor 74, the emergency stop button 79 provided on the motor vehicle 11 is operated. Further, when the crushed stone transporting vehicle 10 is traveling in a section where it is not necessary to spray ballast, the driving of the drive motor 23 may be forgotten. When ballast is sprayed in the space between the rails 17 in a section where it is not necessary to spray ballast, the operator who operates the motor vehicle 11 operates the emergency stop button 79. When the emergency stop button 79 is operated, the control unit 70 stops driving the drive motor 23. Thereby, rotation of the screw conveyor 22 or the screw conveyor 23 is stopped. As a result, the application of the ballast 80 into the gap between the rails 17 is completed.

  In this way, the image of the ballast 80 being scattered is captured by the cameras 72 and 73, and the acquired image is observed. Further, the spread amount detection sensor 74 detects whether or not the ballast 80 to be spread is abnormally spread. In this case, if it can be 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 can also be determined whether or not the ballast 80 is clogged inside the flange 53 and the flange 54. In this way, it is possible to appropriately determine the application state of the ballast 80 from the images obtained by the cameras 72 and 73 and the detection result by the application amount detection sensor 74. Therefore, it is possible to appropriately perform treatment based on the application state of the ballast 80.

  Next, the case where the ballast 80 is spread out of the rail 17 is described. For example, when the operator rotates the operation lever 50 toward the outside of the crushed stone transporting and scattering vehicle 10, the shielding plate 42 slides in the L direction in FIG. 9 along the side wall 21 b of the hopper frame 21. The discharge port 40 is opened by the sliding of the shielding plate 42, and the ballast 80 loaded inside the hopper frame 21 falls through the discharge port 40. The ballast 80 that has fallen from the discharge port 40 moves along the chute 63. Here, the tip of the chute 63 is located outside the gauge of the rail 17. Accordingly, the ballast 80 that has moved to the tip of the chute 63 is scattered outside the rail 17.

  Then, when the application amount of the ballast 80 applied to the outside of the rail 17 reaches the target application amount, the operator rotates the operation lever 50 toward the center of the crushed stone transporting vehicle 10. As a result, the shielding plate 42 slides along the side wall 21b of the hopper frame 21 in the M direction in FIG. The discharge port 40 is shielded by the sliding of the shielding plate 42. Since the discharge port 40 is shielded by the shielding plate 42, the ballast 80 loaded on the hopper frame 21 is stopped from dropping from the discharge port 40. That is, the spraying of the rails 17 outside the gauge is completed. The same applies when any of the operation levers 49, 51, 52 is rotated.

  In this way, by operating the operation levers 49, 50, 51, 52 of the crushed stone transporting and scattering vehicle 10, the ballast 80 can be sprayed outside the rails of the rail 17. When adjusting the spraying amount of the ballast 80, the operating amount of the operating lever to be rotated may be adjusted to adjust the opening amount of the discharge port.

  In this embodiment, the case where the two screw conveyors 22 are arranged so that the rotation axes thereof extend along the rail extending direction and the rotation axes of the respective conveyors are coaxial is described. It is not necessary to use the screw conveyor 22, and the present invention can be implemented even if one screw conveyor 22 is arranged. In addition to arranging the two screw conveyors 22 and 23 so that the respective rotation axes are coaxial, the two screw conveyors 22 and 23 can be arranged in parallel along the extending direction of the rail.
