Crusher for fodder

The invention discloses a kind of forage fodder crushing device, which includes the frame, a feeding funnel on the frame, there has a discharging outlet on the bottom of the feeding funnel, there sets a crushing device driven by power source under the discharging outlet. The crushing device includes a parallel knife shaft, blades groups are set are set on the parallel knife shaft along the axis through blades setting device, each group of blades are distributed along the axial direction evenly, the crushing device is at one side of the discharging outlet, the gap between blade groups sets an adjusting gate which can control the extruding length of blade; the forage fodder is put into the feeding funnel, because of the effect of gravity, the fodder flows to the discharging outlet, and crushed by the blades rotating with high speed, thus it can control the crushing length. The structure of the invention is simple, it is reliable. 本发明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；当把草料防入进料斗后，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，本发明结构简单，使用可靠，具有极大的推广应用价值。
