JP 2004-215638 A

  The cocoon forming machine according to the background art has a problem that, when used for many years, the side surface of the cocoon becomes thick due to oversupply of the embankment amount and so-called thickening of the cocoon occurs. If the cocoon is thick, the crop plantation field area will be reduced, resulting in the disadvantage of reduced crop yield. In addition, there are cases in which it is not possible to thicken due to lack of embankment, etc., when it is desired to thicken because the ridge is thin.

  Therefore, an object of the present invention is to provide a ridge forming machine having a mechanism capable of easily adjusting the thickness of a ridge formed on an old ridge.

  In order to solve the above problems, in the wrinkle forming machine configured by the frame body mounted on the tractor and the wrinkle forming part provided on one side of the frame body, the wrinkle forming part is in a direction orthogonal to the traveling direction. It consists of a banking device composed of a rotary rotary part having a rotating shaft, and a paddle forming apparatus composed of an upper surface roller and a conical disk forming a paddle, the rotary rotary part comprising a large-diameter claw and an old claw for scraping the bottom surface of a paddy fieldか ら Consisting of a rotary shaft having a small-diameter claw that cuts the side surface, and this rotary rotary portion is used by being connected to a tractor characterized in that the relative position in the left-right direction can be varied with respect to the conical disc surface Providing a forming machine.

  Further, in the above ridge forming machine, the embankment cover of the embankment apparatus includes an upper surface cover that covers the upper portion of the rotary rotary portion, a back cover that partitions the back surface, and a guide that extends from the end of the back cover toward the conical disk. The guide cover is provided with a ridge-forming machine that is used by being connected to a tractor characterized in that it can be switched to the left and right with respect to the conical disk large-diameter side edge. .

  In the invention according to claim 1 configured as described above, the rotary rotary portion of the embankment device can change its position in the left-right direction with respect to the conical disk surface that forms the side surface portion of the ridge behind. If the diameter is thick, increase the amount of protrusion of the rotary rotary part to the outside of the conical disk surface, conversely, if you want to thicken the dredging, reduce the protruding amount and adjust the amount of excavation of the old dredge You can adjust the thickness of the cocoon.

  According to the second aspect of the present invention, the guide cover extending from the end of the back cover of the rotary rotary portion of the embankment device toward the conical disc is arranged on the left and right with respect to the conical disc large-diameter side edge. If the old saddle is fine and the amount of soil is less than the specified saddle shape, the angle of the guide cover is set so that the edge of the guide cover is positioned on the upper surface side of the conical disc, and the entire fill that is supplied from the banking device use. In addition, when the old dredging is thick and expanding, the end of the guide cover is positioned on the back side of the conical disc in order to eliminate the excavated soil in the rotary part, and the supply amount of excavated soil is reduced. Then, it becomes possible to form the old iron into a thin shape.

  Furthermore, by combining with the adjustment of the left and right protrusion amounts of the rotary rotary portion described in the invention of claim 1, it is possible to form the ridges with higher accuracy than desired.
