Self-walking type branch crusher

The invention discloses a self-walking type branch crusher. The self-walking type branch crusher comprises a frame, and a crushing bin and a power machine arranged on the frame, wherein a cutter disc set is fixed in the crushing bin through a main shaft; the cutter disc set consists of cutter discs coating the main shaft; two cutter bits are symmetrically fixed on the outer circle of each cutter disc to respectively form a first cutter bit set and a second cutter bit set; each set of cutter bits is arranged by equal angles in the peripheral direction, so that the first cutter bit set and the second cutter bit set are symmetrically and spirally arranged in the axial direction on the outer contour of the cutter disc set; the feed end of the crushing bin is fixedly connected with a feed bin; a discharge port is formed in the discharge end of the crushing bin; a feed port of the feed bin is fixedly connected with a feed hopper; a fixed cutter is horizontally fixed at the bottom of the feed bin; the power machine drives the main shaft to drive the cutter disc set to rotate anticlockwise; and the first cutter bit set and the second cutter bit set intermittently fit the fixed cutter in sequence to finish the material planing. The self-walking type branch crusher solves the crushing difficulty of large-diameter hard wood branches, and is high in efficiency.
