Therefore, according to the above-mentioned real axis example, the flying out of the cut soil (C) scraped and conveyed by the packet (2) due to the centrifugal force in the front upper half is caused by the rotation operation mechanism, that is, the hydraulic cylinder (1). The cutting curve is effectively blocked by the blocking control frame plate (11) positioned above the ground level (GL);
If the cutting soil (C") is allowed to fly out from inside due to centrifugal force, the projecting cutting ± (C") is prevented from moving upward, to the side, and excessively backward by the guide control frame plate (12). scattering or dissipation of the material is prevented, and the material can be guided more efficiently and smoothly onto the conveyor.

Therefore, due to the increase in rotational speed, the packet (2)
The scraping efficiency is significantly increased, the scraping performance is improved, and a large amount of cut soil can be smoothly transferred to a conveyor and discharged.

Therefore, by greatly improving the scraping performance as the rotational speed increases, it is possible to reduce the wheel diameter and reduce the weight, reduce the weight of the machine, reduce fuel consumption, reduce costs, etc. Effects can be obtained.
