The invention relates to the technical field of agricultural machines, in particular to a hydraulic-driving vineyard cold-proof-soil clearing machine. The hydraulic-driving vineyard cold-proof-soil clearing machine comprises a machine frame, and soil clearing assemblies are arranged on the side face of the machine frame, and comprise standing columns; first joints are rotationally connected on the machine frame and can rotate in the Y direction, third joints are fixed on the standing columns, second joints are arranged between the first joints and the third joints, are rotationally connected with the first joints, and can rotate in the Z direction, and the third joints are rotationally connected with the second joints and can rotate in the X direction; hydraulic oil cylinders are arranged between the second joints and the machine frame, and piston rods of the hydraulic oil cylinders are hinged to the second joints; rotating frames for installing the tails of the hydraulic oil cylinders are rotationally connected on the machine frame, and can rotate in the Y direction relative to the machine frame in the Y direction. According to the hydraulic-driving vineyard cold-proof-soil clearing machine, the rotary power of a clearing disc is derived from a hydraulic motor, the using time of mechanical transmission is reduced through using of hydraulic driving, the mechanical structure is further simplified, the mechanical volume is decreased, and the transmission efficiency is improved.
