The invention discloses an efficient
pruning robot for needle-leaf trees, which comprises a frame body, a cutter, a guide claw, climbing tracks, clamping claws, a guide roller, an advancing roller, a universal shaft, a
brake arm, a moving connecting rod and a
hydraulic cylinder, wherein the cutter is mounted at the top of the frame body, the guide claw is mounted at the upper end of the frame body, and the climbing tracks are arranged on two sides of the frame body. Clamping claws are sequentially installed on the outer frame body from top to bottom at intervals, a universal shaft at the top of the
brake arm is in linkage installation with the advancing roller to serve as climbing auxiliary movement support, the
tail end of the
brake arm is connected with a
hydraulic cylinder through a movement connecting rod, and the
hydraulic cylinder conducts telescopic braking to achieve opening and closing of the brake arm. According to the efficient
pruning robot for needle-leaf trees, the device is attached to the bottom of the
tree trunk, the clamping claw and the advancing roller are braked by the hydraulic cylinder and are braked with a
tree trunk in a surrounding mode, when the advancing roller is vertically installed, the climbing track serves as a power source to drive the straight up and down cutters of the device to
impact and shear branches at the designated position, and when the advancing roller is obliquely located and installed, the device spirally moves upwards to prune the branches on the whole annular face.
