As a configuration of a ridge forming disk of a conventional ridge forming machine, a configuration according to Japanese Patent No. 3148678 by the same applicant is known. The paddle forming machine according to this gazette is mounted on a tractor and moved along the paddle forming part, and a paddle device that supplies soil to the paddle forming part in a raised state, and a paddle installed at the back of the moving direction of the padding apparatus A cylindrical rotating body that rotates and passes the soil over a portion where the soil is raised, and a rotational driving power supply side that is attached to the rotational driving force supply side of the cylindrical rotating body. As the diameter increases, the surface has an inclined surface toward the center of the cylindrical rotating body, and the surface is divided into radial divided pieces, and each divided piece is provided with an advancing angle with respect to the traveling direction. Each of the pieces has a clearance angle and a conical rotating body connected in a zigzag shape in a side view.
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 wrinkle forming apparatus according to the prior art, the disk, which is a rotating body, always rotates while causing slipping. Therefore, when used for a long period of time, replacement of parts is necessary due to wear. However, since the disk, which is a rotating body, is not a cylinder with the same diameter, the peripheral speed is different on the side closer to the axis of rotation and the side away from it, and the degree of wear is different. Therefore, there is a problem that it is very uneconomical to replace the entire integrated disk.

  In addition, the shape of the intersection between the upper surface and the side surface of the ridge when forming the ridge is easy to collapse if it is simply an acute angle that intersects the flat part of the upper surface and the side surface. There have been demands for various types such as those having corners inclined in a chamfered shape, those having an R shape, and those having different sizes. For this reason, it is necessary to prepare and cope with disks formed in respective shapes. In addition, when the user changes the shape of the corner using the same machine, a plurality of integrally configured disks are required, which is uneconomical.

  For this reason, an object of the present invention is to allow parts to be replaced by dividing them according to the degree of wear, and to easily change the shape of the intersection between the upper surface and the side surface of the heel, and to have a heel-forming disk having a good heel-forming performance. It is to provide a forming machine.

  In order to solve the above-mentioned problem, there is a pile-up device that moves along the crease formation location and supplies soil to the crease formation location in a raised state, and a crease formation device installed at the rear in the traveling direction of the build-up device. The crust forming device has a cylindrical disk that rotates while passing over the crust forming portion that is in a raised state, and is attached to the rotational driving force supply side of the cylindrical disk and increases in diameter toward the rotational driving force supply side. Each of which is composed of a three-divided unit of a conical disk having an inclined surface directed toward the center of rotation of the cylindrical disk and an intermediate disk positioned at an intermediate portion of the conical disk and the cylindrical disk. Provided is a wrinkle forming machine characterized in that it is secured.

  Further, in the above-described scissor forming machine, the surface of the conical disk is composed of radially divided pieces directed toward the center of rotation, and the divided pieces have a substantially arcuate curved surface when viewed from the side, and the divided pieces are adjacent to each other. The present invention provides a scissor forming machine characterized in that the rear end portion is overlapped and connected to the front side in the rotational direction, and each is detachably fixed to the disk frame.

  With the configuration described above, the disk, which is the rotating body of the ridge forming apparatus, is composed of a cylindrical disk, a conical disk, and an intermediate disk at an intermediate portion that connects the cylindrical disk, and each of them is detachably fixed and integrated. Therefore, when replacing parts due to wear, it is very economical because the parts can be partially divided and replaced according to the degree of wear.

  In addition, the intermediate disk of the intermediate part of the rotating body is a part that molds the intersection of the upper surface and the side surface of the reed at the time of forming the reed. If you want to change the shape of the intersection in the same machine, you only need to replace the intermediate disk of the desired shape.

  The surface of the conical disc is composed of radial pieces directed toward the center of rotation, and each disc is detachably fixed to the disc frame. However, it is very economical because it is only necessary to replace the damaged piece without replacing the entire rotating body.

  Further, the divided pieces on the surface of the conical disc form a substantially arc-shaped curved surface in a side view, and are configured by overlapping and connecting the rear end portions on the front side in the rotation direction of the adjacent divided pieces. Advancing angles that are lower in the front direction and higher in the rear direction are provided, and the adjacent divided pieces rotate continuously, so that intermittent pressure acts on the ridge-forming surface and the soil is easily removed, making it easier for air and moisture to escape. Can form tightly compacted ridges.
