The utility model discloses a pneumatic and mechanical combined type grape vine root soil cleaning device. Bottom plate, a splayed frame is fixed to one side of the outer wall of the top of the bottomplate through bolts. An obliquely-arranged spring column is hinged to the middle of the outer wall of one side of the splayed frame; a soil cleaning plate is hinged to the end, away from the splayedframe, of the spring column; two plough plates are fixed on the outer wall of the bottom of the soil cleaning plate through bolts; the two plough plates are distributed in a splayed shape, the ends, close to each other, of the two plough plates are of triangular structures, a rectangular groove is formed in the side, close to the splayed frame, of the outer wall of the bottom of the bottom plate,springs distributed at equal intervals are fixed to the inner wall of the top of the rectangular groove through screws, and the bottom ends of the springs are fixedly connected with the outer wall ofthe top of the soil cleaning plate through screws. Mechanical soil cleaning is achieved, soil cleaning efficiency is improved, labor cost is reduced, the soil cleaning effect is better, damage possibly caused by stones in a soil layer to equipment is effectively reduced, the service life of the equipment is prolonged, and the device is reasonable in arrangement, high in stability and high in practicability.
