  The wrinkle forming device includes a cylindrical rotating body that rotates perpendicularly to the wrinkle and passes through the upper face of the wrinkle, and a conical rotating body that has a conical surface that passes through the side face of the wrinkle and forms the side face of the wrinkle. The soil piled up by the earthing device provided in is pressed while rotating to form the ridge. For this reason, the heel-forming device is pushed in a direction away from the heel by the reaction force for pressing, and inconvenience occurs such that the tractor equipped with the heel-forming machine cannot travel straight ahead. In order to solve such a problem, in the wrinkle forming machine disclosed in the above-mentioned prior art documents and the like, the outer peripheral portion of the disk-shaped grounding ring facing the traveling direction is inserted into the ground, and the wrinkle forming apparatus It is configured to receive a reaction force generated from the conical rotator and to go straight.

  However, the magnitude of the reaction force also changes depending on the moisture condition and soil quality of the soil forming the ridge, and there is a problem that the soil and foreign matter adhere to the ground ring and float up, and it is insufficient to receive the reaction force. there were.

  In view of the above, an object of the present invention is to provide a ridge forming machine that can easily operate a tractor during an operation and perform an appropriate ridge coating operation.

  In order to solve the above-mentioned problem, the invention described in claim 1 is a scissor forming machine that is provided in a main body frame that is connected to a traveling vehicle, and that offsets a working portion to the side of the traveling vehicle to perform a scissor forming operation. The working portion is moved along the ridge forming portion, and a pile portion that rakes the soil to the ridge formation portion by a tilling rotor and supplies the pile to a raised state, and a ridge provided behind the pile portion in the moving direction. A molding part, and the cocoon molding part is a working part that presses and passes through the cocoon forming portion where the soil is raised in the earthing part, and molds the cocoon, and the cocoon molding part Has a cylindrical rotator for forming the upper surface of the heel and a conical rotator attached to one end of the cylindrical rotator to form the side of the heel, and the conical rotator is located above and below the main body frame. Provided on the rotating end side of the transmission frame that is freely rotatable in the direction, The transmission frame can be adjusted up and down, and the transmission frame is provided with an up and down position adjustment, and a lower end is inserted into the surface of the field and a disc-shaped grounding ring is rotated. The grounding ring is provided at a position away from the conical rotator with respect to the mold to be formed, the conical rotator side in the left-right direction is planar, and the other side is formed in a truncated cone shape. We propose a dredging machine characterized in that a scraper that peels off the adhering soil is provided on the trapezoidal slope.

  In order to solve the above-mentioned problem, in the invention according to claim 2, the rotating shaft of the grounding ring is provided to be inclined toward the rear side of the conical rotating body with respect to a vertical plane perpendicular to the traveling direction in plan view. A wrinkle forming machine according to claim 1 is proposed.

  According to this invention, the conical rotator is provided on the rotating end side of the transmission frame that is rotatable in the vertical direction with respect to the main body frame, and the lower end portion is inserted into the field surface and rotated in the traveling direction. Since the grounding ring is provided on the transmission frame so that the vertical position can be adjusted, even if the cone-shaped rotating body is vertically adjusted, the amount of the grounding wheel stuck is constant, and the adjustment can be easily performed. In addition, the grounding ring has a flat shape on the side of the conical rotator in the left-right direction and a shape formed on the other side in the shape of a truncated cone. Since the reaction force acts as a component force to the ground side where the reaction force is inserted, the force is dispersed and the reaction force is sufficiently received. Further, since the scraper for peeling off the adhering soil is provided on the truncated cone-shaped slope portion, the soil and the foreign matter do not adhere and the performance of the grounding ring is not impaired.

  Further, the rotation axis of the grounding ring is inclined toward the rear side of the conical rotator side with respect to the vertical plane orthogonal to the traveling direction in plan view, so that the heel forming part is formed on the heel side by forward traveling. Since the grounding ring is caused to press against the ground, it acts to counteract the reaction force from the conical rotator side, and the conical rotator can be pressed against the forming heel side to form a strong heel. For this reason, it is possible to provide a kite forming machine that is easy to handle the tractor during work and that can perform an appropriate kite coating operation.
