[0014] Compared with the prior art, the present utility model has the following beneficial effects:

[0015] 1. In this device, an installation mechanism is provided. The fixing plate is welded and fixed to the rear end of the vehicle body. Two plug rods with rectangular grooves are arranged at the bottom of the rear side of the frame body. The plug rods are inserted into the connecting grooves, so that the frame body is fixed to the fixing plate. When it is necessary to remove the rotary tiller from the vehicle body, push the rotary tiller backward, so that the rotary tiller drives the frame body to move backward through the connecting shaft, side rods, and adjusting rods. The plug rods move to the rear side of the connecting grooves, so that the connecting grooves lose the limit on the plug rods. At this time, by lifting the frame body upward, the plug rods can be pulled out of the connecting grooves, and the frame body and the connected rotary tiller can be quickly disassembled from the vehicle body, thus eliminating the need to disassemble each connecting rod on the frame body from the rotary tiller when disassembling the rotary tiller.

Rectangular positioning grooves are opened on both sides of the frame body, and a telescopic block is movably installed in the insertion block within the limiting plate. During use, the rotary tiller is adjusted to the normal working position, and then the insertion block is inserted into the positioning groove at the corresponding position, so that the limiting plate is fixed on the frame body and the limiting plate abuts against the bottom of the overturning frame. When the rotary tiller is not in use, it will be driven upward by the overturning frame and retracted. When the rotary tiller is used again, the overturning frame drives the rotary tiller to be adjusted so that the overturning frame is flipped to the position where it abuts against the limiting plate. In this way, the rotary tiller can be quickly positioned to the position of the previous work, thereby maximizing the control of the working range of the rotary tiller in the vertical direction each time it is used.
