[Industrial application fields]
The present invention relates to a wrinkle forming machine having a reversing mechanism for a wrinkle forming work section, and relates to a configuration of a tractor mounting section.
[0002]
[Prior art]
A conventional scissor forming machine having a reversing mechanism for a scissor forming work section includes a mounting mast that engages with a work equipment mounting frame provided at the rear of the tractor, and an input shaft that transmits drive through a universal joint from the tractor PTO shaft. A first drive case, a second drive case that hangs below the first drive case, a ridge forming work section that includes a banking device and a ridge forming apparatus, and the ridge formation work section from the second drive case in the horizontal direction. The heel forming device of the heel forming working unit is fitted to the end of the support frame, can be moved up and down, can be fixed at any position up and down, and can respond to changes in the height of the heel It has become.
Further, the second drive case suspended below the first drive case is pivotably fitted to form a rotating part, and the wrinkle forming work part is swung left and right to move forward and backward. to allow the coating work, there is a ridge forming machine having an inverted structure that does not non-working portion occurs.

[Problems to be solved by the invention]
In order to set the working posture of the hook forming machine according to the shape of the old paddle, the paddle forming machine according to the configuration of the prior art shown in FIG. 8 is engaged with the mounting frame provided at the rear of the tractor and mounted. Is set by raising and lowering the tractor three-point link mechanism, and the kite height is set by rotating the kite forming apparatus up and down. With this work posture held, the wrinkle work is performed by advancing the tractor. When the padding work is performed up to the final end of the old paddle, an unplowed work part is generated in the entire length range from the tip of the tractor to the paddle forming device. At this time, the second drive case is rotated 180 degrees around the rotating part, so that the cocoon forming work part is reversed, and the uncultivated working part can be laid in reverse by moving the tractor backward. However, there are cases where a wide variety of tractors exist and each has its own three-point link mechanism for raising and lowering the work implement, so that the mounting frame is inclined forward. When the work posture during forward work is set in this state, as shown in FIG. 8Y, the rotation axis X that turns the ridge forming work part is often inclined forward by α degrees with respect to the vertical direction. If it is rotated 180 degrees in order to perform the reverse operation from this working posture state, as shown in FIG. 8Z, the hook forming device is positioned deep in the soil. For this reason, there is a problem that the adjustment range of the working posture of the ridge forming machine has to be widened, resulting in a large body configuration. In addition, there is a problem that the work posture must be set again, and there is an annoyance that must be performed each time the work direction changes. Moreover, although the structure which arrange | positions the upper surface processing machine of a cage | basket in front of the earth-laying apparatus is known, there exists a fault that a body length is long and enlarges.
