Loosely fit the hitch pins 5, 5 into 7.27, and pivot the upper part of the mast 6.6 to the top link 28 which is pivotally connected to the rear upper part of the power agricultural machine 26, and connect the two PTO shafts of the power agricultural machine 26. If the rotary shafts 11 are connected by the flexible transmission shaft 30, the disc cam 14 will swing the crank 15 up and down about the pin shaft 16 as the two PTO shafts rotate nine times, and When this crushing device 31 moves forward together with 26, the knife body 1 that has penetrated into the ground receives resistance in the direction of the arrow B, and since the rolling contact plate 3 is always in contact with the roller 19, it is not affected by the vertical swing of the crank 15. Accordingly, the knife body 1 performs reciprocating rocking motion around the pin shaft 10.

なお、図示の実施例においては掘進体２の後端に弾丸状
の作溝体３２をチェノ３３にて係着している。In the illustrated embodiment, a bullet-shaped groove-forming body 32 is attached to the rear end of the digging body 2 by a chino 33.

したがって、ＰＴＯ軸２軸回９転してナイフ体１と掘進
体２が前進するとき、ナイフ体１と掘進体２はピン軸１

必要な動力は少くて済むものである。Therefore, when the knife body 1 and the digging body 2 move forward by rotating the PTO shaft 2 axes 9 times, the knife body 1 and the digging body 2
Since it oscillates back and forth in the direction of movement centering on 0, the hard plowing platform is crushed in small increments and effectively by the vibration of the knife body 1 and digging body 2, which is necessary for the crushing operation. It requires less power.

そして、石塊があっても、この振動のために石塊は前後
にゆすぶられるので、ナイフ体１などの進行は支障なく
行われるものである。Even if there is a stone block, the stone block is shaken back and forth due to this vibration, so that the knife body 1 etc. can move forward without any problem.

。As mentioned above, the tiller crushing device according to this invention is provided with a plurality of mounting holes 15C in the arm portion 15b of the L-shaped crank 15, which is provided to swing back and forth, and these mounting holes 15C are provided. A roller 19 is selectively supported in the hole 15C, and the roller 19 is attached to the upper part of the knife body 1 by a spring bias.
By adjusting the pivot position of the roller 19 up or down by selecting the mounting hole 15C, the swing amplitude of the knife body 1 can be changed to a larger or smaller amount.

ことができるのである。Therefore, the efficiency of plowing and crushing can be improved by changing the oscillating width of the knife body 1 depending on the viscosity of the soil or the hardness or softness of the plowing plate. This means that even a hard plowing board can be crushed reliably, and in the case of a soft plowing board, work efficiency can be improved by increasing the swing width and increasing the advancing speed of the knife body 1. The swing width adjustment of the knife body 1 is as follows.
This can be easily done by changing the pivot position of the roller 19.

にもナイフ体１が妄動することがなく、安全である。In addition, since the upper part of the knife body 1 is brought into contact with the roller 19 by the biasing force of the spring 22, the impact exerted on the knife body 1 from the tiller at the time of crushing the tiller is buffered, and the swinging drive of the knife body 1 is reduced. Damage to the mechanism can be prevented, and since the upper part of the knife body 1 is always in contact with the roller 19 even when the knife body 1 is lifted above the ground, the knife body 1 can be easily moved when the device is transported. It is safe and does not cause confusion.
