12 to 15 are drawings showing a third embodiment, in which a worm 51 and a worm wheel 5 are placed on a ground plate 5.
While providing a warm gear box 49 containing 2,
A pair of left and right square wheels 53, 53 are provided on both the left and right sides of the ground plate 5, and the worm 51 is rotated through the rotation action of the square wheels 53, 53.

Although other illustrations are omitted, in a fourth embodiment, one end of the hydraulic cylinder, that is, the tip of the piston rod, is pivotally connected to the ground plate 5, and a small amount is sent to the hydraulic cylinder via a feed mechanism. It is also possible to push out the piston rod downward by sending in oil, and to push down the ground plate 5 through the pushing action of the piston rod.

Next, its operation will be explained regarding the first embodiment.

The hopper 10 is filled with rice husks, the winding frame 18 is wound with a corrugated pipe 19, and the corrugated pipe 19 is passed through the guide pith 35 to the diesel 1 1
It is guided into the introduction member 12 formed at the rear of the diesel engine 1111, and is set so that its one end protrudes slightly rearward than the lower end of the diesel engine 1111, while the adjustment village 6 is manually operated with the handle punch 6'. By rotating it, the ground plate 5 is set so as to be pulled up to the uppermost position.

After each part is set as described above, the traction link 3 is lowered via the hydraulic lift 4, so that the lower half of the diesel 11 is set in the ground.

The lower half of the diesel 11 can be set in the ground either by forcing it into the ground or by digging a hole at the setting position in advance.
Then, with the diesel 11 set at a depth where the ground plate 5 is in contact with the ground surface, the bulldozer A is driven at a very low speed by the engine drive of the bulldozer A, while the PTO shaft is 2 to rotate.

The rotational power of the PrO shaft 2 is transmitted to two pulleys 22, 22' mounted on the rotating shaft 21 via the rotating shaft 21 mounted on the gear box 201. The rotational power transmitted to one of the pulleys 22 is transmitted to the belt 2
3. The decelerated state is transmitted via the booley 30 to the drive shaft 28 installed in the vibration box 27, and the drive shaft 28 is driven to rotate, while the rotational power transmitted to the drive shaft 28 is further It is transmitted to the driven shaft 29 side through the meshing action of a pair of upper and lower gears. That is, a state is obtained in which both shafts 28 and 29 rotate in opposite directions at the same speed within the vibration box 27. By rotating both shafts 28 and 29 in opposite directions at the same speed in this manner, the diesel 11
Vibration is applied to Further, the rotational power transmitted to the other pulley 22' is transmitted to the rotating shaft 13 via the belt 16 and the pulley 15, and the floating blade 14 mounted on the rotating shaft 13 is rotated, and the crank village 17 is rotated. ', the thick azusa rod 17 swings.

And, due to the action of both the floating wire 14 and the loss-making stick 17, no cavity ○ phenomenon occurs at the bottom of the hotsuber 10.
It is possible to smoothly feed a certain amount of the rice into the inlet 12 on the side of the diesel 11. The rotational power transmitted to the rotating shaft 13 is further transmitted to a pair of pulleys 15.
The rotating shaft 30' is transmitted through a belt 41 that is strung between pulleys 15' and 40, and a feed pawl 42 fixed to the rotating shaft 37 is rotated. .

Each time the feed pawl 42 rotates once, the engagement pin 44^ of the pin gear 44 that is engaged with the feed pawl 42 is fed one frame at a time. In other words, the adjusting punch 6 makes one revolution only after the rotating shaft 37 that fixes the feed pawl 42 rotates the same number of engagement pins 44' that are fixed to the pin gear 44. It is. That is, the male thread part 4
5 and the male screw portion, the ground plate 5 is pushed down by the pitch of the screw. In other words, by pushing down the ground plate 5, the underframe 9 and the diesel 11 which is pivotally connected to the underframe 9 are pushed upward as a whole. By continuously repeating this action, the depth of the culvert gradually becomes shallower as the culvert is dug by the Diesel 11. After completing one stroke of the adjustment punch 6, the ground plate 5 can be returned to its old position by unwinding it through the handle punch 6' with the feed claw 42 set at the neutral position. It is.

In this way, the above-mentioned actions are continuously repeated in each part of the bulldozer A, the drainage culvert forming machine B, and the gradient setting mechanism C, so that the vertical groove is cut open by the blade part 11' of the diesel 11. In addition, the bullet 25 excavates the culvert.

At the same time as the culvert is excavated by the bullet 25 in this way, the corrugated pipe 19 is buried inside the culvert, while rice husk is obediently stuffed into the vertical groove and the outer periphery of the corrugated pipe 19. I'm going. The present invention has the above-described configuration, and with the above configuration, as the culvert is dug through the vibration action of the diesel 11 in the front and rear direction, the excavation depth of the culvert is gradually decreased. This made it possible to automatically adjust the slope of the underground construction so that it could be shallowly traversed.

As a result, it became possible to form a culvert with a gentle slope overall, and it became possible to quickly drain the water collected inside the culvert to the outside.
