The drive unit 30 has a large-diameter drive drum 32 fixed to one end of the rope winding member 29, and a drive rope 33 wound around the drive drum 32, and pulls the drive rope 33. As a result, the rope winding member 29 is formed so as to be able to rotate in the direction of winding the first repositioning rope 31a and the second repositioning rope 31b via the drive drum 32.

The rice husk filling device 11 for an underdrain formed in this way is the starting end of the existing rice husk underdrain 12 in the field, and the elevating link of the tractor 14 with the center line of the tractor 14 aligned with the direction of the existing rice husk underdrain 12. 14a is operated to ground the warp member 25, and the rice husk filling portion 19a and the guide member 18 in the lower half of the hopper 19 are inserted into the ground by a predetermined amount. In this state, the tractor 14 is advanced along the existing rice husk culvert 12, and the rice husk 13 is charged into the hopper 19 from the rice husk input port 19d. By pulling out the folding table 24 in the horizontal direction when the rice husks 13 are put in, the rice husks in the bag can be simply knocked down with the bag containing the rice husks placed on the folding table 24. Since the rice husk 13 can be charged into the rice husk charging port 19d, the rice husk 13 charging operation can be easily performed.

Further, since the rice husk filling device 11 for the underdrain is connected to the tractor 14 by the parallel link 16 and is formed so as to be swingable in the left-right direction, the existing rice husk underdrain 12 is bent in the left-right direction. When there is, the guide member 18 moves in parallel in the left-right direction according to the bent state of the rice husk culvert 12. That is, since the portion filled with the rice husk is softer than the hardness of the groove side wall in the existing rice husk culvert 12, the pointed portion 18b at the tip of the guide member 18 advances through the soft portion, and the existing rice husk culvert 12 The rice husk filling portion 19a moves in parallel in the left-right direction according to the bending state of the rice husk. As a result, the rice husk filling device 11 for culverts can be advanced along the existing rice husk culvert 12 with a relatively light force, and the existing rice husk culvert 12 can be filled with new rice husks 13. Good drainage in rice husk culverts can be restored.

When the end of the existing rice husk culvert 12 is reached, the elevating link 14a raises the rice husk filling device 11 for the culvert higher than the ground to change the direction, and the tractor 14 is run to run the tractor 14 to start the next existing rice husk culvert 12. The rice husk filling device 11 for an underdrain is moved to the rice husk filling device 11 and the same rice husk filling operation is performed. At this time, if the center line of the tractor 14 and the center line of the rice husk filling device 11 for the underdrain are deviated from each other, the position of the tractor 14 with respect to the existing rice husk underdrain 12 and the rice husk filling device for the underdrain will be performed during the next rice husk filling operation. The position of 11 is different in the left-right direction, making it difficult to insert the rice husk filling device 11 for culverts into the existing rice husk culvert 12, and the movable amount of the rice husk filling device 11 for culverts in the left-right direction is different. Depending on the bent state of the rice husk culvert 12, the rice husk filling device 11 for culvert may not be able to follow. Therefore, the hopper repositioning means 26 is operated to reposition the rice husk filling device 11 for culvert to the central position.

For example, as shown in FIG. 6, when the rear connecting member 17 moves to the right (upward in FIG. 6) with respect to the front connecting member 15 mounted on the tractor 14, it is provided at the left end of the front connecting member 15. The first repositioning rope 31a is pulled out from the rope winding member 29 so that the rope fixing member 27a and the rope guide member 28b provided at the right end of the rear connecting member 17 are separated from each other. On the other hand, although the distance between the rope fixing member 27b and the rope guide member 28a is shortened, the rotation of the rope winding member 29 when the first repositioning rope 31a is pulled out causes the second repositioning rope 31b to become the rope winding member 29. It is unwound from. Therefore, the first repositioning rope 31a is in a stretched state, and the second repositioning rope 31b is in a loosened state. Further, the drive rope 33 is wound around the drive drum 32 due to the rotation of the drive drum 32 accompanying the rotation of the rope winding member 29.

In this state, when the drive rope 33 is pulled and the drive rope 33 is pulled out from the drive drum 32 to rotate the drive drum 32, the rope winding member 29 moves with the rotation of the drive drum 32 and the double return ropes 31a, It rotates in the direction of winding 31b. As a result, both the repositioning ropes 31a and 31b are wound around the rope winding member 29, respectively, and the first repositioning rope 31a in a stretched state pulls the rope fixing member 27a, and the front connecting member 15 is centered. Return to position. On the other hand, the second repositioning rope 31b gradually changes from the loosened state to a stretched state, and finally, when the front connecting member 15 is repositioned to the central position, both the repositioning ropes 31a and 31b are stretched. Therefore, the drive rope 33 cannot be pulled out. Therefore, the front connecting member 15 and the rear connecting member 17 connected by the parallel link 16 can be arranged side by side by a simple operation of pulling the driving rope 33 until the driving rope 33 cannot be pulled out. The center line of the tractor 14 and the center line of the rice husk filling device 11 for underdrain can be aligned with each other. As a result, the rice husk filling device 11 for the culvert can be easily and surely inserted into the next existing rice husk culvert 12, and the rice husk 13 can be surely filled into the next existing rice husk culvert 12. ..

Further, by grounding the sled member 25 according to the depth of the existing rice husk culvert 12, it is possible to reliably fill the 13 with a predetermined amount of new rice husks over the entire length. Further, by forming the side wall bending portions 20a and 20a of the side walls 20 and 20 of the hopper 19 with a curved surface that is convex toward the inside of the hopper 19, the rice husks 13 thrown into the hopper 19 are used in the rice husk filling port 19c. It can be dropped smoothly toward it.

When a heavy machine such as a bulldozer or a power shovel can be used, it is also possible to use the heavy machine as a traveling body by using an appropriate connecting member for connecting the heavy machine. Further, when the amount of the rice husk filling device for an underdrain inserted into the ground can be adjusted by an elevating link or the like, the sled member can be omitted. Further, a stirrer or the like for promoting the fall of rice husks can be installed in the hopper. Further, the structure of the drive unit is arbitrary, and for example, when winding the return rope, the drive drum can be directly rotated by a handle or the like without using the drive rope.
