る。 Then, large clods of soil are guided downward by the free end portions 21 of each rod-like member 15 of the screen 12, and clods of soil or fine soil smaller than the gap between the free end portions 21 of each rod-like member 15 are allowed to fall through the gap. It passes through and is released onto the rear leveling plate 22, but at this time, since each rod-shaped member 15 has an elastic portion 14 wound around a coil spring near its upper end, elastic deformation of the elastic portion 14 in the width direction occurs. By this and the rocking action, clods of soil and weeds are prevented from being caught between the rod-shaped members 15 and clogging, and a cultivated soil layer with a coarse lower layer and a denser upper layer is formed. This surface portion is leveled by a leveling plate 22.

整地される。 In this case, since the soil prevention plate 11 is arranged inside the cover body 8, the soil prevention plate 11 and its elastic deformation prevent tilled soil from adhering to the inside of the cover body 8. Since the screen 12 is vertically disposed facing the rear part of the rotary work body 3, large clods are guided downward by the free end portions 21 of each rod-shaped member 15, and each rod-shaped member Clods of soil and fine soil smaller than the gaps between the screens 15 and 15 pass through the gaps and are thrown toward the flat plate 22 at the rear. When a clod of soil is thrown, the free end portion 21 of each rod-like member 15 of the screen 12 is elastically deformed in the elastic portion 14 by the impact, and swings due to the reaction, and the free end portion 21 of each rod-like member 15 of the screen 12 is elastically deformed by the impact. The independent elastic deformation and rocking motion of the end portions 21 prevent clods and weeds from getting caught between the rod-like members 15, thereby preventing the lower layer from being coarse and the upper layer from being dense. A cultivated soil layer is formed, and the surface thereof is leveled and graded by the leveling plate 22.

According to the present invention, the plurality of rod-shaped members of the screen attached to the rear end portion of the cover body are formed such that the elastic portion is wound around the upper end portion in the shape of a coil spring to be elastically deformable in the width direction, and Since the lower part of this elastic part is vertically provided as a free end part, the free end parts of the plurality of rod-shaped members are surely elastically deformed in the width direction in the elastic part by the earth clod released from the rotary work body. It oscillates with the
Therefore, the distance between the free end portions of each of the plurality of rod-shaped members of the screen can be easily varied, and it is possible to reliably prevent clods of soil, weeds, etc. from being caught between the free end portions and clogging the screen. be able to. Then, large clods are guided downward by the free end portions of each rod-shaped member, and small clods and fine soil are thrown backward from between the free end portions of each rod-shaped member, so that the lower layer is It is possible to reliably form a cultivated soil layer with a coarse upper layer and a denser layer, and level the surface with a leveling plate. In addition, each elastic part of the screen is wound like a coil spring around each rod-shaped member so that it can be elastically deformed in the width direction, so the structure is simple and easy to manufacture, and there is no particular increase in cost.
