[0008] A crushing cutter head is installed on the outer side of the crushing hammer head.

[0009] Preferably, the shapes of the connecting groove and the mounting block are matched, and the mounting block is a "convex" structure. This design can prevent the mounting block from escaping from the connecting groove, thereby stabilizing the position of the mounting plate so that the mounting plate is positioned on the transmission shaft.

[0010] Preferably, the limit rod and the support rod are snap-connected to each other, and the limit through hole opened at the end of the limit rod corresponds to the positions of the first through hole and the second through hole that are interconnected. This design allows the mounting rod to smoothly pass through the first through hole, the second through hole and the limit through hole, and limit and lock the crushing hammer head, so that the crushing hammer head can be installed on the support rod.

[0011] Preferably, the end of the crushing hammer head close to the support rod is an "n"-shaped structure, and the crushing hammer head is sleeved on the outside of the support rod. This design can fit the crushing hammer head and the support rod, and limit the connection between them to ensure that the crushing hammer head moves with the support rod.

[0012] Preferably, the crushing cutter heads are evenly distributed at the ends of the crushing hammer heads, and the crushing cutter heads are pointed structures. This design allows the crushing cutter heads to assist the crushing hammer heads in crushing the wood.

[0013] Preferably, the front end of the connecting groove passes through the transmission shaft, and the transmission shaft and the mounting plate are slidably connected. This design can facilitate the installation block to be moved out of the connecting groove and the installation plate to be disassembled and assembled.

[0014] Compared with the prior art, the beneficial effects of the utility model are:

[0015] (1) The new wood crusher hammer is easy to fix. The mounting plate is sleeved on the outside of the transmission shaft and is limited by the connection groove and the mounting block. The mounting plate can be flexibly disassembled and assembled, and the crushing hammer head assembled on the rear side of the mounting plate can also be flexibly disassembled, which is convenient for comprehensive maintenance and cleaning;

[0016] (2) The new wood crusher hammer is easy to fix. The limiting rod on the inner side of the crushing hammer head is stuck in the supporting rod. The crushing hammer heads on the same horizontal plane can be limited by the mounting rod passing through the first through hole, the second through hole and the limiting through hole in sequence, and can be locked by using a threaded fixing nut. The crushing hammer head can be assembled quickly and conveniently, and the subsequent disassembly and maintenance are also relatively convenient. BRIEF DESCRIPTION OF THE DRAWINGS
