The transfer of the crushed material can be completed automatically, and it is convenient to use.

[0020] 3. This feeding mechanism is provided with a sliding block. When the crushing knife cuts into hard materials and the cutting resistance increases, the resistance on the crushing knife is transmitted to the slider. The slider is subjected to an increased counter-thrust from the crushing knife, which increases the movement tendency of the slider inside the protective slide. The slider drives the spherical extrusion block to increase the extrusion pressure on the arc groove. Correspondingly, the arc groove increases the extrusion thrust on the spherical extrusion block, and the extrusion pressure of the spherical extrusion block on the extrusion switch increases.

The spiral feeding roller is driven to rotate by the discharging motor. When the spiral feeding roller rotates, the material inside the discharge bin can be discharged through the discharge pipe, which facilitates automatic discharging and does not require manual operation, saving manpower. The bottom of the discharge bin is connected to the movable bracket through a rotating table, and the discharge bin can be driven to rotate by the rotating table, so that the discharge pipe mouth on the discharge bin can face any direction, and the adjustability is good.
