し、熔着手段によってもよい。A large number of cutters 10 are fixedly mounted on the rotary cylinder 7. This cutter is in the form of a cutting knife in which the tip is narrower than the root, and the blade corresponding to the blade of the cutting knife is the first blade 11, and the edge on the side opposite to the first blade 11 is also formed. Second
With a blade 12. In this cutter 10, the first blade 11 is oriented in the rotation direction of the rotary cylinder 7. Further, the large number of cutters 10 are fixed at equal intervals in the axial direction of the rotary drum 7, and three are provided radially at the fixed positions (fourth illustration). As shown in FIG. 4, the cutter 10 may be fixed to the rotary cylinder 7 by screwing means or welding means.

でなく、牽引力を受けて土壌を切削することになる。When the device of the present invention having the above-described configuration is connected to a towing drive vehicle and towed on the soil, among the cutters radially fixed to the rotary drum 7, the cutter 10 facing downward is in the soil. Pierce into. If the device of the present invention is pulled in this state,
The device of the present invention is pulled to the left in Fig. 4, and the rotary drum 7 rotates counterclockwise in Fig. 4 due to the engagement of the soil with the downward cutter 10 stuck in the soil. As a result, the first blade 11 of the next cutter 10 penetrates into the soil and cuts the soil. On the other hand, at this time, since the cutter 10 that is facing downward is pulled while the second blade 12 is engaged with the soil, not only the action of the second blade 12 engaging with the soil, It receives traction and cuts the soil.
