本实用新型的工作原理为：将石子原材料从进料斗4放入，通过第一电机16带动第一传动轮8，由第一传动轮8带动皮带轮3的转动，在动挤压板5绕悬挂偏心轴2向静挤压板6摆动,在摆动过程中位于两块挤压板之间的石子受到压碎、劈裂和弯曲等综合作用，由于动挤压板5和静挤压板6的表面的挤压锥块20，开始时,压力较小, 使物料的体积缩小,物料之间互相靠近、挤紧，当压力上升到超过物料所能承受的强度时,即发生破碎，动挤压板5的每一个周期性运动就使物料受到一次压碎作用,由于重力的作用下落到碾压轮21处，由第二电机19带动第二传动轮、碾压轮21，进行二次碎石，由传送带 24对二次碎石的石子传送到筛网14处，而高压喷头13可以对石子进行清洗，最后穿过筛网14由出料口27排出。The working principle of the utility model is as follows: put the stone raw material from the feed hopper 4, drive the first transmission wheel 8 through the first motor 16, and drive the rotation of the belt pulley 3 by the first transmission wheel 8, and rotate around the moving extrusion plate 5 The suspension eccentric shaft 2 swings towards the static extrusion plate 6, and the stones located between the two extrusion plates are crushed, split and bent during the swing process. Due to the dynamic extrusion plate 5 and the static extrusion plate 6 The surface of the extrusion cone 20, at the beginning, the pressure is small, so that the volume of the material is reduced, and the materials are close to each other and squeezed tightly. When the pressure rises beyond the strength that the material can bear, it will be broken and dynamically squeezed. Every periodic movement of the pressing plate 5 causes the material to be crushed once, and falls to the rolling wheel 21 due to gravity, and the second motor 19 drives the second transmission wheel and the rolling wheel 21 for secondary crushing. The stones are conveyed to the screen 14 by the conveyor belt 24 for secondary gravel, and the high-pressure nozzle 13 can clean the stones, and finally pass through the screen 14 and are discharged from the discharge port 27.
