Japanese Patent No. 3148678

  A conventional wrinkle forming apparatus includes a cylindrical rotating body that rotates orthogonally to a wrinkle and passes through the upper face of the wrinkle, and an inner rotary plate that has a conical surface that passes through the wrinkle side face and forms the fist side face. The peripheral speed of the body is set faster than the traveling speed of the traveling vehicle, and the heel is tightened by the slip action. In the prior art, the conical rotating body is formed in a radial divided piece to make the heel inclined surface tightly sealed, and it is formed in a zigzag shape in a side view, or an advancing angle is provided with respect to the traveling direction, and adjacent divided pieces have a clearance angle. Kneaded with intermittent pressure applied.

  These are intended to make the inclined surface of the cocoon that tends to collapse more firmly, but the soil and the old cocoon soil applied to the inclined surface are uniformly applied with the same moisture and density. This makes it difficult to cause a difference in soil quality between the two, which causes a phenomenon of peeling off from the boundary surface. Moreover, the above phenomenon is further promoted when rainwater or the like penetrates into the boundary surface portion from above. In order to prevent these, it is necessary to apply the upper surface portion of the ridge and the inclined surface together to suppress the peeling of the inclined surface soil with the upper surface soil. In the conventional wrinkle forming apparatus, a technique for forming the inclined surface more firmly has been proposed, but it is not so important to harden the upper surface portion of the wrinkle. If it is soft, it will not be possible to support the inclined surface portion, or rainwater will easily penetrate from the upper surface portion to the boundary surface, which will cause the phenomenon of heel peeling off.

  Therefore, an object of the present invention is to provide a wrinkle forming apparatus capable of forming the upper face portion of the wrinkle more firmly.

  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 culm forming device includes a cylindrical rotating body that rotates and passes the soil on the ridge-forming portion that is raised, and a rotational driving force supply side that is attached to the rotational driving force supply side of the cylindrical rotating body. The outer diameter of the cylindrical rotating body has a substantially arc-shaped curved surface portion with respect to the rotation axis. A wrinkle forming machine characterized in that a plurality of divided pieces are connected by overlapping the rear side on the upper surface on the front side in the rotational direction of adjacent divided pieces.

  Further, in the wrinkle forming machine, the rear end portion in the rotation direction of the split piece is provided with a protruding portion that protrudes outward from the outer periphery of the curved surface portion having a substantially arc shape with respect to the rotation axis of the split piece. A wrinkle forming machine is provided.

  With the above-described configuration, the soil supplied in the raised state to the ridge formation area of the old paddle by the earth filling device rotates the conical rotating body and the cylindrical rotating body, and the traveling vehicle is advanced so that the new paddle However, since the plurality of adjacent divided pieces of the cylindrical rotating body forming the upper surface part of the cylindrical rotating body are connected by overlapping the rear side on the front side in the rotation direction, the front side is low and the rear side is high. It is constructed, and while embedding the embankment in the lower part on the front side, it gradually applies pressure at the high part on the rear side, and this is repeated by rotating, so it is kneaded with intermittent pressure acting, and in the embankment Air and moisture can easily escape, and a strong heel upper surface portion can be formed.

  As a result, it is possible to firmly support the sloped surface of the kite, suppress the penetration of rainwater or the like into the boundary surface with the old kite, and prevent the peeling-off phenomenon. Further, by projecting the rear end portion of the split piece, a stronger intermittent pressure can be applied to form the ridge upper surface portion, and the soil continuously adsorbed on the surface of the split piece is separated by the projecting portion. Even in the soil having strong adsorptivity to the cocoon forming portion, the soil does not carry around due to adsorption, and the cocoon can be formed without peeling off the applied soil.
