Note that, since the driving shaft 41 needs to perform power splitting for the soil breaking device 2 and the conveyor belt during power transmission, the first driven shaft 44 and the second driven shaft 45 are concentrically spaced; in the power splitting process of the transverse conveyor belt 31, the second driven shaft 45 also simultaneously drives the longitudinal conveyor belt 32, so that the second driven shaft 45 is a continuous whole in the auxiliary gear box 43, only one driven bevel gear 48 is sleeved in the middle of the second driven shaft 45, and the driven bevel gear 48 is meshed with the driven bevel gear 48 at the end of the third driven shaft 46 to complete power output of the two driven shafts in different rotating directions and drive the two conveyor belts to drive in different transverse and longitudinal conveying directions.

The tractor of the invention is a crawler tractor, and the running gear is composed of a guide wheel, a follower wheel, a thrust wheel, a driving wheel and a crawler. When in operation, the driving wheel winds the crawler belt to do circular motion, and the thrust wheel rolls on the track of the crawler belt to move forwards or backwards. The soil-sticking agent has the advantages of small pressure per unit area of soil, good adhesion performance to soil, no skid and the like, and has better passing performance in moist and soft soil. The crawler tractor is highly matched with the operation working condition in the invention, thereby weakening the secondary rolling of the ground soil on one hand, and flexibly operating on soft soil on the other hand, keeping the highly flexible maneuverability of the crawler tractor and effectively improving the working efficiency.

It is emphasized that by adopting the soil cleaning machine, the manual operation is greatly liberated, the soil on the walking path is easily cleaned while the tractor moves, and the working efficiency is effectively improved.
