Description of the Related Art Conventionally, a ring-shaped mounting frame has been provided on a lateral drive shaft, and a large number of crushed earth plates (lugs) made of flat strip-shaped iron plates are provided laterally on the outer periphery of the mounting frame at intervals in the circumferential direction. There is a known rotor for crushing soil that constitutes a basket-type rotor for scraping, and can scramble the surface soil of a field cultivated by this rotor to perform scraping work.

繰り返されて機体を振動させる等の問題があった。In the crushed soil rotor used in the conventional scraping device, a single flat strip-shaped flat plate which is provided laterally over the crushed soil width in the circumferential direction at a coarse interval is used as the rotor rotates. It is designed to be rushed in at once, and the thin clay plates that have rushed into the soil can be pulled out at once, and it may be shocked by excessive resistance to intrusion into the soil at the time of rushing in, or suddenly when it goes out. However, there was a problem that the machine was vibrated due to repeated no-load conditions and large changes in transmitted power.

When the airframe is run while being rotationally driven while the rotor 7 is supported so that its lower portion penetrates into the soil, the crushed earth plate 70 of the rotor 7 has its working surface facing downward when it penetrates into the soil. The soil is crushed, and as it rotates near the lowest point, it gradually becomes an oblique posture and crushes the crushed soil while scraping it in the direction of rotation, and when it comes out of the ground, the plate surface goes up and down and scratches mud soil. Leaving with less skipping.

Therefore, the resistance at that time is reduced and the vibration or the like given to the machine body can be suppressed. Further, the projecting teeth 7b formed at the tips of the adjacent crushed earth plates 70 alternately act to suppress vibration and the like and can crush the soil finely, so that good crushed soil can be performed.

Working surface (lower surface) is inclined forward with a small forward inclination. When it penetrates into the soil, the angle of inclination is gradually reduced, and it acts as a crushing force on the assumption that it becomes horizontal just ahead of the axis (Figs. 4 and 5). Then, in the process of turning a little from the front of the lowermost part, directly below the axis, and further to the rear, the soil crushing action is performed while converting to the rearward posture in the vicinity. Furthermore, in the rear part, the vertical posture is gradually taken out to the ground, and in this final stage, the mud rarely jumps backward or upward.

If the cultivated soil mass enters during the period, the tip portions (front edges in the rotation direction) of the crushed soil plates 7A, 7B, 7C, 7D collide with this and crush the soil. At this time, the rotor 7 formed in each unit body is provided with the crushed earth plates 70 that are adjacent to each other in the left-right width direction with the phases shifted while maintaining good soil discharge with a sufficient space in the circumferential direction. The crushed earth plate 70 absorbs the impact when it plunges into the soil.

Soil can be leveled. By performing the scraping action with such suppression by a large number of each of the crushed earth plates 7A, 7B, which rotate at a high speed, it is possible to perform a good surface scraping while leveling without violent airframe vibration. it can.
