[Problems to be solved by the invention]
According to the known technique, when the tractor has traveled to the final end of the old fence, an unplowed work portion is generated in the entire length range from the tractor to the padding work machine. It is necessary to perform a disengagement engagement operation by a clutch of the second input shaft provided rearward from the first input shaft for rotating from the first input shaft for inputting from the tractor.
At this time, there is a problem that the engagement between the spline and the clutch requires a fine accuracy and the engagement is not achieved after a long period of use. In addition, the first transmission case for driving the rotary and the second transmission case having the glazed body are provided, and there is a drawback that the rotation mechanism is complicated.
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 which the whole body length becomes long and enlarges.
[0004]
[Means for Solving the Problems]
In order to solve the above-mentioned problems, a main transmission box having an input shaft transmitted from the tractor PTO shaft, a machine frame that protrudes to the left and right of the main variable box and is attached to the rear of the tractor, and a main transmission box are provided. A sub-shift box that is directly coupled with the vertical axis extending downward, a support frame that transmits from the sub-transmission box to the earthing device and the ridge forming device, and the sub-transmission box rotates about the vertical axis of the main transmission box. In the cocoon forming machine which is configured to be movable and immediately after the culverting device and immediately before the culm forming device, the culvert top surface earthing device is arranged, when the uncultivated work part of the old culvert is moved backward, The support frame is rotated 180 degrees, the engagement piece provided on the machine frame protruding from the main transmission box is engaged with the bracket provided on the side of the support frame, and the stopper pin is inserted and fixed. Characteristic It is obtained by providing the ridge forming machine.
[0005]
[Action]
Since it comprised as mentioned above, after the tractor progresses to the last edge part of an old fence, in order to form the eaves | work of an unplowed work part, it is 180 degree | times with the subtransmission box whose longitudinal axis is concentric with respect to the main transmission box. When it is rotated, the embankment part and the ridge forming device are arranged so as to protrude toward the opposite side of the previous step where the ridge has been formed. With this arrangement in the rotated state, the tractor is moved backward as it is, and is in a state of being painted, so that it is easy to attach to and detach from the tractor transmission section.
In addition, since the dredging top surface cutting device is arranged immediately after the cradling device and immediately before the dredging device, weeds and topsoil on the dredging surface can be eliminated at the same time as normal dredging, and it is located in the inner part of the entire body. Therefore, it is compact without any special protrusions by the upper surface processing mechanism.
In addition, the engagement piece provided on the machine frame protruding from the main transmission box and the bracket provided on the side of the support frame are engaged and fixed by inserting the stopper pin. There are few.
