FIG. 8 is a diagram illustrating a state in which a clamp member is attached to the ballast spreader according to the present embodiment. FIG. 9 is a view showing a state in which a ballast spreader is attached to the road-rail vehicle of this embodiment.

  The ballast spreader 1 of the present embodiment is attached to the road-rail vehicle 100 for work. First, the ballast spreader 1 and the road-rail vehicle 100 are placed on the track R so as to be able to travel. The rear tilt of the loading platform 101 of the road-rail vehicle 100 is removed in advance.

  Next, as shown in FIG. 8, the platform is tilted so that the height of the tilt hinge 103 of the lateral tilt 102 of the load platform 101 of the road-rail vehicle 100 matches the height of the connecting member 64 of the connecting portion 6. After the adjustment, the connecting member 64 is hooked on the tilt hinge 103. In the present embodiment, the bar-like connecting member 64 is hooked on the notch of the tilt hinge 103. It should be noted that the height of the tilting hinge part 103 and the connecting member 64 may be adjusted such that the height of the connecting lever 63 or the connecting member 64 of the connecting part 6 can be adjusted. The structure of the tilt hinge 103 and the connecting member 64 may be hooked by a hook or the like. In addition to being hooked, it may be changed as appropriate, such as being inserted into a hole or fitted and fixed.

  Next, the inclination of the loading platform 101 of the road-rail vehicle 100 is returned to the original position, and the road-rail vehicle 100 is clamped by the clamp member 7. The clamp member 7 inserts the connecting shaft portion 62 of the connecting portion 6 and is fixed to the frame 2.

  To attach the clamp member 7, the inclination of the loading platform 101 of the road-rail vehicle 100 is returned to the original position, the clamp portion 71 of the clamp member 7 is inserted into the connection shaft portion 62 of the connection portion 6, and the clamp member 7 is attached to the frame. 2 fixed. It is preferable to install a rubber cover (not shown) or the like above the connecting shaft portion 62 to reduce damage caused by the ballast hitting. Subsequently, as shown in FIG. 9, the clamping portion 73 is clamped by clamping the rear flange 104 of the lower part of the loading platform 101 of the road-rail vehicle 100 between the clamping portion 71 and the contact plate 72 of the clamping member 7. In this manner, the ballast spreader 1 is attached to the road-rail vehicle 100. In addition, in this embodiment, although the clamp member 7 was retrofitted to the ballast spreader 1, you may attach to the connection shaft part 62 previously.

  By using the clamp member 7, the ballast spreader 1 can be stably attached to the road-rail vehicle 100.

  In the present embodiment, as the connection of the ballast spreader 1 to the road-rail vehicle 100, the connection by the connection member 64 is performed first and the connection by the clamp member 7 is performed later, but the reverse order may be used. The connection by the connecting member 64 and the connection by the clamp member 7 are performed at two places on the left and right.

  Next, a description will be given of when traveling on a track.

  FIG. 10 is a diagram illustrating a state during travel of the road-rail vehicle 100 to which the ballast spreader 1 of the present embodiment is attached.

  As shown in FIG. 10, the ballast spreader 1 is connected to the road-rail vehicle 100 by a connecting portion 6 and a clamp portion 7. The ballast spreader 1 can travel on the track R in a connected state together with the road-rail vehicle 100. At this time, the front wheel portion 5b is suspended from the frame 2 by a chain or the like.

  Next, the time of ballast application will be described.

  FIG. 11 is a diagram illustrating a state of the road-rail vehicle 100 and the ballast spreader 1 at the time of ballast spraying according to the present embodiment. FIG. 12 is a diagram illustrating a state of the ballast spreader 1 at the time of ballast spraying according to the present embodiment.

  As shown in FIG. 11, at the time of ballast spraying, the road-rail vehicle 100 tilts the loading platform 101 and drops the accumulated ballast into the hopper 3 of the ballast sprayer 1. In the ballast spreader 1, when the loading platform 101 is inclined, first, the connecting lever 63 of the connecting portion 6 shown in FIG. 9 rotates around the connecting hinge portion 62. When the loading platform 101 continues to be tilted, the front wheel portion 5b of the ballast spreader 1 rotates forward, and the ballast spreader 1 tilts toward the road-rail vehicle 100 side. When the ballast spreader 1 is inclined toward the road-rail vehicle 100, the side tilt 102 enters the receiving opening 3 a of the hopper 3. In this state, the ballast is smoothly received from the loading platform 101 into the hopper 3. The side tilt 102 enters the inside of the receiving opening 3 a of the hopper 3, so that the side tilt 102 guides the ballast to the inside of the hopper 3, and the ballast that spills from the side of the receiving opening 3 a of the hopper 3. The amount is reduced.

  The ballast received by the hopper 3 is separated into the first discharge part 31, the second discharge part 32, and the third discharge part 33 inside the hopper 3. However, the discharge part having the discharge lid on the upper part does not accept ballast.

  The ballast received by the first discharge part 31 of the hopper 3 is discharged from the first discharge port 31 a by operating the first opening / closing part 41. The 1st opening-and-closing part 41 rotates the 1st attachment shaft 41c and the 1st opening-and-closing lid 41a by rotating the 1st opening-and-closing lever 41b. Therefore, unless the first opening / closing lever 41b is rotated, the ballast is not discharged, and by rotating the first opening / closing lever 41b, the ballast is discharged from the first discharge port 31a. In this way, the ballast can be easily discharged by rotating the first opening / closing lever 41b.

  The amount of ballast to be discharged is adjusted by rotating the first opening / closing lever 41b stepwise to adjust the opening degree of the first opening / closing lid 41a relative to the first discharge port 31a. Is possible. For example, the first opening / closing lever 41b can be rotated at a plurality of stages corresponding to a predetermined angle, and the first opening / closing lid 41a is set to be opened at a plurality of stages according to the rotation angle of the first opening / closing lever 41b. Thus, it becomes possible to adjust the discharge ballast amount.

  The first discharge port 31a of the hopper 3 is disposed between the two tracks R. Accordingly, the ballast discharged from the first discharge port 31a falls between the two tracks R.

  The ballast received by the second discharge part 32 of the hopper 3 is discharged from the second discharge port 32a by operating the second opening / closing part 42. The second opening / closing part 42 rotates the second opening / closing lever 42b, whereby the second mounting shaft 42c and the second opening / closing lid 42a rotate. Therefore, unless the second opening / closing lever 42b is rotated, the ballast is not discharged, and by rotating the second opening / closing lever 42b, the ballast is discharged from the second discharge port 32a. In this way, the ballast can be easily discharged by rotating the second opening / closing lever 42b.

  The amount of ballast to be discharged is adjusted by rotating the second opening / closing lever 42b stepwise so that the opening degree of the second opening / closing lid 42a with respect to the second discharge port 32a can be adjusted stepwise. Is possible. For example, the second opening / closing lever 42b can be rotated at a plurality of stages corresponding to a predetermined angle, and the second opening / closing lid 42a is set to be opened at a plurality of stages according to the rotation angle of the second opening / closing lever 42b. Thus, it becomes possible to adjust the discharge ballast amount.

  The second discharge port 32a of the hopper 3 is disposed outside the two tracks R. For example, in FIG. 12, it is arranged on the left outer side of the track R. Therefore, the ballast discharged from the second discharge port 32a falls to the outside of the two tracks R, that is, to the left outside of the track R in FIG.

  The ballast received by the third discharge part 33 of the hopper 3 is discharged from the third discharge port 33 a by operating the third opening / closing part 43. The third opening / closing portion 43 rotates the third opening / closing lever 43b, whereby the third attachment shaft 43c and the third opening / closing lid 43a rotate. Therefore, unless the third opening / closing lever 43b is rotated, the ballast is not discharged, and by rotating the third opening / closing lever 43b, the ballast is discharged from the third discharge port 33a. In this manner, the ballast can be easily discharged by rotating the third opening / closing lever 43b.

  The amount of ballast to be discharged is adjusted by rotating the third opening / closing lever 43b stepwise so that the opening degree of the third opening / closing lid 43a with respect to the third discharge port 33a can be adjusted stepwise. Is possible. For example, the third opening / closing lever 43b can be rotated at a plurality of stages corresponding to a predetermined angle, and the third opening / closing lid 43a is set to be opened at a plurality of stages according to the rotation angle of the third opening / closing lever 43b. Thus, it becomes possible to adjust the discharge ballast amount.

  The third discharge port 33a of the hopper 3 is disposed outside the two tracks R. For example, in FIG. 12, it is arranged on the right outer side of the track R. Accordingly, the ballast discharged from the third discharge port 33a falls to the outside of the two tracks R, that is, to the right outside of the track R in FIG.

  By arranging the first discharge port 31a, the second discharge port 32a, and the third discharge port 33a of the hopper 3 outside and between the two tracks R, the first discharge port 31a, the second discharge port 32a, and the third discharge port R are arranged. It becomes possible to scatter the ballast falling from the discharge port 33a to a position where it does not interfere with the two tracks R. Accordingly, it is possible to omit the wiping operation of the ballast remaining on the track or on the fastening device after spraying.

  Further, the road-rail vehicle 100 can travel in a state as shown in FIG. Therefore, the road-rail vehicle 100 and the ballast spreader 1 connected to the road-rail vehicle 100 can travel while spraying the ballast, and the ballast remaining on the track after the spray or on the fastening device over a wide range. The wiping work can be omitted.

An opening / closing part 4 that opens and closes the discharge port of the hopper 3, a wheel part 5 that is supported by the frame 2 and is placed on the track, and a vehicle that is supported by the frame 2 and travels on the track and is loaded with ballast. Since the connecting portion 6 is provided, the structure is simple, and there is mobility, and the working time can be shortened and the cost can be reduced.

  Further, the hopper portion 3 protrudes downward in the center with respect to the space between the two tracks R, and the first discharge portion 31 having the first discharge port 31a formed at the end portion and one outer side of the two tracks. A second discharge portion 32 having a second discharge port 32a formed at an end portion that protrudes downward from the side, and an end portion that protrudes downward from the side corresponding to the other outer side of the two tracks. 3rd discharge part 33 in which the 3rd discharge port 33a was formed in, and the ballast which falls from the 1st discharge port 31a, the 2nd discharge port 32a, and the 3rd discharge port 33a interferes with two track R It becomes possible to spread to the position which does not carry out, and it becomes possible to abbreviate | omit the wiping work of the ballast which remains on a track | orbit or a fastening device after spreading.

  The opening / closing part 4 includes a first opening / closing part 41 for opening / closing the first discharge port 31a, a second opening / closing part 42 for opening / closing the second discharge port 32a, and a third opening / closing part 43 for opening / closing the third discharge port 33a. Therefore, the ballast can be easily discharged by opening and closing the lid.
