Description

  The present invention is connected to a tractor and travels in parallel with the old paddle.The former paddle and a part of the paddy field scene below the old paddle are cut once, and the cut soil is embanked on the old paddle. The present invention relates to a crease forming machine that forms a new crease on an old crease by compacting with a rotating crease forming device.

As a background art, for example, as disclosed in Japanese Patent Application Laid-Open No. 2004-215638 by the same applicant, a ridge forming apparatus including a top roller that forms a cylindrical ridge upper surface and a conical disk that forms a ridge side surface, and a traveling direction There is known a ridge forming machine that includes a banking device provided with excavation claws on a rotating shaft that is orthogonal to the surface. The embankment device is used to cut out part of the rice paddy field scene on the side of the old paddy and the lower part of the old paddy to fill the old paddle, and the above-mentioned paddle forming device slips and compacts to form a new paddle. is there.
JP 2004-215638 A

  In the cocoon forming machine according to the above-described background art, when used for many years, the side surface of the cocoon becomes thick due to oversupply of the embankment amount, and a so-called thickening phenomenon may occur. If the cocoon is thick, the crop plantation field area will be reduced, resulting in the disadvantage of reduced crop yield. Also, if there are irregularities on the side of the old ridge or if the old ridge is meandering, even if you try to form a new ridge in a straight line, there will be a tendency to form a ridge that follows the old ridge because the amount of embankment is constant. It is in.

  Therefore, an object of the present invention is to provide a ridge forming machine having a mechanism that can easily adjust the thickness of the ridge formed on the old ridge, regardless of the shape of the old ridge.

  In order to solve the above-mentioned problem, in the scissor forming machine composed of a frame body attached to the tractor and a scissor forming part provided on one side of the frame body, the scissor forming part is a rotary rotary part having excavation claws. The embankment device consists of an upper surface roller that forms a ridge and a ridge formation device that consists of a conical disk. The concave disk can be rotated freely so that a part of the side surface of the old ridge can be scraped off at the front of the embankment device. A wrinkle forming machine is provided.

  Moreover, in the above-mentioned ridge forming machine, the concave disk provided in the front part of the embankment device is provided with the concave surface obliquely inward in the traveling direction and obliquely upward, and the position can be adjusted left and right, and removed when not working. Alternatively, the present invention provides a ridge forming machine characterized in that it can be held in the upper part of the embankment device.

  Further, in any one of the above crease forming machines, the embankment cover of the embankment device includes an upper surface cover that covers the upper portion of the rotary rotary portion, a rear surface cover that partitions the rear surface, and a conical disc that extends from the end of the rear surface cover. This guide cover is provided with a ridge forming machine characterized in that the guide cover is provided so that the angle can be switched between right and left with respect to the end portion on the large diameter side of the conical disc.

  In the invention according to claim 1 configured as described above, the concave disk provided in front of the embankment device is not yet operated by the concave disk when the bowl forming machine advances forward by the bowl forming work. Progress while scraping off part of the side. For this reason, since a wrinkle forming operation is performed after a part of the thickened wrinkles is cut and thinned, the formed wrinkles are not thickened, and the amount of scraping can be increased and thinned. In addition, even if the side surface of the old ridge is uneven or meandering, the ridge is formed after being formed into a certain shape by the concave disk, so that uniform formation is performed regardless of the state of the old ridge.

  According to the second aspect of the present invention, since the concave disk has the concave surface directed obliquely inward and upward in the traveling direction, the front part of the concave disk is a side part on which old weeds and the like grow. It is easy to cut into weeds, and weed roots are easily cut at the end face of the disk. Furthermore, since the concave disk is rotatably provided, it rotates by the resistance force from the side surface of the heel as it advances, and the soil scraped off at the front is discharged from the back of the concave disk to a position away from the old heel, The embankment device makes it difficult to return to the old fence. In addition, the amount of soil removed can be adjusted by adjusting the concave discs on the left and right sides, so the thickness of the ridge can be adjusted easily, and it can be removed and held in the upper part when not needed, making conventional work possible. The corresponding range of different field conditions becomes wider.

  According to the third aspect of the present invention, the guide cover extending from the end of the back cover of the rotary rotary of the embankment device toward the conical disc is angled to the left and right with respect to the conical disc large-diameter side edge. If the old paddle is thin and the soil volume is less than the specified paddle shape, the guide cover end is positioned on the upper surface side of the conical disc and the entire fill supplied from the banking device is used. To do. In addition, when the old dredge is thick and expanding, the end of the guide cover is positioned on the back side of the conical disc to eliminate the excavated soil in the rotary section, and the amount of excavated soil supplied is reduced. Then, it becomes possible to form the old iron into a thin shape. When there is a lot of soil scraped off by the concave disk, it can be easily dealt with such as escaping from the guide cover, and it is possible to cope with a wide range of field conditions by combining the scraped amount of the concave disk and the adjustment of the guide cover. .
