Japanese Patent No. 3148678

  A conventional wrinkle forming apparatus comprises a cylindrical rotating tool that rotates orthogonally to a wrinkle and passes through the upper surface of the wrinkle, and an inner rotary plate that has a conical surface that passes through the wrinkle side surface and forms the wrinkle side surface. The peripheral speed of the rotating body is set to be faster than the traveling speed of the traveling vehicle, and the rod is tried to be compacted by the slip action. In the above prior art, the conical rotating body is formed into a radially divided piece in order to tighten the heel more firmly, and is formed in a zigzag shape when viewed from the side, or the adjacent divided pieces are connected with a clearance angle by providing a forward angle with respect to the traveling direction. And kneaded with intermittent pressure.

  However, when soil moisture is low and dry, the elasticity of the soil decreases, the followability of the conical rotating part to the soil deteriorates, and it is not possible to form a hard-tight ridge, or a part of the soil that is partly hard When the cone-shaped rotating part hits, there is a problem that the entire cone-shaped rotating part escapes to the outside of the kite and the slip action is less likely to occur, and the hardness of the kite around the hard clot portion is deteriorated.

Accordingly, an object of the present invention is to provide a cocoon forming apparatus capable of forming a cocoon that is firm and independent of the soil quality of the cocoon forming soil.

  In order to solve the above-described problem, a pile-up device that is moved along the ridge-forming portion and supplies soil to the ridge-formation portion in a raised state, and a ridge-forming device that is installed at the rear in the moving direction of the pile-up device. The crust forming device has a cylindrical rotating portion that allows the soil to pass over the crust-forming portion that has been raised, and is attached to the rotational driving force supply side of the cylindrical rotating portion and goes to the rotational driving force supply side. It is composed of a conical rotating part having a large diameter and an inclined surface directed toward the center of the cylindrical rotating part. The conical rotating part is divided into radially divided pieces, and each divided piece rotates in a side view. It is formed to have a substantially arc-shaped curved surface portion with respect to the rotation axis provided with an advancing angle with respect to the direction, and arranged so that the rear side is superposed on the front side of the adjacent divided pieces, and the superposition An elastic body is interposed in the part to support the rear side of the split piece We propose a ridge forming machine according to claim.

  In addition, the elastic body interposed in the overlapping portion of the divided pieces constituting the conical rotating portion is a cylinder from the outer peripheral side of the conical rotating portion to the inner peripheral side along the radial overlapping portion toward the center side of the cylindrical rotating portion. The present invention proposes a wrinkle forming machine described in the above-mentioned column 0004, which is provided in a strip shape over the rotating part side.

  With the above-described configuration, the conventional conical rotating part is made into a radially divided piece, the advancing angle is provided with respect to the traveling direction, the adjacent divided pieces are superposed, and the action of applying intermittent pressure is lost. Without placing the rear side on the front side of the adjacent divided pieces, and by interposing an elastic body in the overlapped portion, the rear portion in the rotational direction of the divided pieces can move flexibly, Even if there is little moisture and the elasticity of the soil is inferior, the followability of the conical rotating part to the soil is very good, and the rear part in the rotating direction of the split piece is flexible even if the conical rotating part hits a part of the hard clot Since only the divided piece with which the hard mass part abuts is pushed outward, the entire cone-shaped rotating part escapes outward, and the pressing force is reduced without decreasing the pressure. Can be formed.

  Further, the elastic body interposed in the overlapping portion of the divided pieces constituting the conical rotating portion is a cylindrical rotation from the outer peripheral side of the conical rotating portion to the inner peripheral side along the radial overlapping portion toward the center side of the cylindrical rotating portion. By providing a belt-like shape over the part side, there is no space for the soil to enter the superposed part, and the effect of the elastic body due to the clogging of the superposed part of the soil is not hindered, and a good wrinkle forming operation can be performed.
