[0007] Optionally, the top of the extension plate is symmetrically fixedly connected to the bottom end of the auxiliary column, and the top end of the auxiliary column is movably inserted into the rotary tiller body.

[0008] Optionally, the driving assembly includes a driving pulley, a transmission belt, and a driven pulley, and the driven pulley is coaxially fixedly connected to the end of the rotary shaft of the rotary blade assembly.

[0009] Optionally, the driving pulley is fixedly arranged concentrically on the side of the transmission wheel, the diameter of the driving pulley is larger than the diameter of the driven pulley, and the outer walls of the driving pulley and the driven pulley are commonly sleeved with a same transmission belt.

[0010] Optionally, the vertical plate is rotatably connected to anti-slip wheels on both sides of the driven pulley, and the vertical plate is rotatably connected to a pressure wheel on the top of the driven pulley.

[0011] Optionally, the bottom height of the vertical plate is higher than the height of the horizontal section of the transmission track, and the bottom end height of the rotary blade group is lower than the bottom height of the vertical plate.

[0012] Compared with the prior art, the utility model has the following advantages:

[0013] 1.
