摘要:近年来，随着我国经济建设的发展，在很多领域的生产实际中，对各种木质物料粉碎机的需求越来越大。根据木质物料粉碎机用途的不同，研制出满足各种要求的木质物料粉碎机已成为目前迫在眉睫的紧要任务。

  本机的机架、上盖都采用了铸件，降低了整机的重心；发动机和主轴之间通过皮带传动，缓和了载荷冲击；主轴通过两个圆锥滚子轴承与机架连接；刀盘和主轴之间采用平键联接；飞刀用垫块和螺栓固定。飞刀采用螺旋曲面方式依次摆放多把短刀。

Abstract：In recent years, with the economic development in our country, and in many fields in the actual production, for a variety of wooden material grinder increasing demand. According to the wooden material grinder of different applications, developed to meet the various requirements of the wooden material grinder has become the urgent task for current imminent.

The machine's rack, about the top head has used the casting  to reduce the machine's center of gravity, Strengthened the stability of complete machine effectively; Between the engine and the main axle adopts the belt transmission to relax the load impact, reduced the harm of overload which brings for the major component such as fly cutter；The connection of main axle and rack is two circular cone roller, to prevent the main axle have great beating; The connection of cutter head and main axle is flat key, Coordinates closely；The fly cutter uses the bolt and cushion to be fixed, Reliable and stable, The fly cutter stretches out the quantity to be able to adjust，And advantageous for disassembling and the replacement. Rack is equipped with wheels, can be driven by the traction machine，Suitable to use in the urban green residues and the trail level lumber processing.
