Forage crusher

The utility model discloses a forage crusher, comprises a machine frame and a feed hopper arranged above the machine frame. The bottom of the feed hopper is provided with a discharge port, and a crusher driven by power source is arranged below the discharge port. The crusher comprises a cutter axle which is arranged horizontally; Cutter groups which are composed of a plurality of cutters are arranged in even intervals along the horizontally arranged cutter axle the cutter shaft in axial direction; the cutters of each cutter group are equispaced along the radical direction of the cutter axle. The inner part of an interstice of the cutter groups on one side of the discharge port of the crusher is provided with a regulating grid plate which can control the projected length of the cutters. A lower grid plate is arranged below the crusher. When forage is put inside the feed hopper, the forage goes automatically to the discharge port under gravitational force; the forage is crushed by the cutters of the crusher which are rotating in high speed. The regulating grid plate can regulate the projected length of the cutters, in order to control the crushing length of the forage. The utility model has simple structure and reliable use. 本实用新型公开了一种所述的草料粉碎装置，它包括机架、机架上方设有进料斗，所述的进料斗的底部设有出料口，出料口的下方设有由动力源驱动的粉碎装置，所述的粉碎装置包括水平设置的刀轴，水平设置的刀轴上沿轴向通过刀具安装装置间隔均布安装有由多把削刀组成的削刀组，每个削刀组的多把削刀沿刀轴的径向均布设置，粉碎装置位于出料口一侧的削刀组的间隙内设有可控制削刀伸出长度的调节栅板，粉碎装置的下方设有下栅板；当把草料放入进料斗后，因为重力的作用，自动走向出料口，经粉碎装置高速旋转的削刀切碎，调节栅板可以调节削刀伸出长度，从而可控制切碎长度，本实用新型结构简单，使用可靠，具有极大的推广应用价值。
