In the embodiment, the transmission box 13 adopts a transmission box. In the embodiment, the transmission box comprises a power input shaft 1 for receiving the power source, a power transmission shaft 3 and a power output main shaft, the power input shaft 1 is provided with a power input gear assembly in axial sliding fit; the power transmission shaft 3 is provided with a power transmission gear assembly, the power output main shaft is provided with a power output gear assembly 6 and a power direction-changing gear 7 which is rotatable relative to the power output main shaft, the power direction-changing gear 7 is combined with the power transmission shaft 3, the power input gear assembly can be controlled to engage with the power transmission gear assembly or the power direction-changing gear 7 to transmit power to the power transmission shaft 3, the power output gear assembly 6 is used to transmit the power of the power transmission shaft 3 to the power output main shaft; the power output main shaft is used to transmit the power to the traveling part through the traveling input shaft 12 and to the working part through the tool input shaft 11.

[0030] The power transmission shaft 3 is provided with a power shifting tooth assembly. The power shifting tooth assembly can be provided with one, and in the embodiment, the power shifting tooth assembly includes a power shifting tooth one 9 coaxially arranged on the power transmission shaft 3 and engaged with the combination tooth 8, and a power shifting tooth two 10 coaxially arranged on the power transmission shaft 3.

[0044] The driving bevel gear and the driven bevel gear are engaged through the intermediate bevel gear;

[0045] The driven bevel gears are engaged at different positions along the circumference of the intermediate bevel gear, which changes the angle between the corresponding cutter power input shaft 1 and the walking power input shaft 1, which has the following advantages:
