When the discharge pipe 10 is discharging materials, the servo motor 904 can be started to drive the cam 903 to rotate, and by using the elastic force of the fixing spring 910, the anti-blocking rod 902 can slide up and down to realize the dredging operation of the discharge pipe 10, and prevent the crushed solid waste from being blocked inside the discharge pipe 10 and affecting the discharge and collection rate.

[0036] In this embodiment, the top end of the anti-blocking rod 902 is mushroom-shaped, and a clamping structure is formed between the bottom end of the anti-blocking rod 902 and the inside of the installation groove 909. By using the mushroom-shaped anti-blocking rod 902, it is convenient to dredge and prevent blockage inside the discharge pipe 10.

[0037] In this embodiment, the cross-sectional shape of the fixing block 905 is arc-shaped, and the fixing block 905 and the cam 903 are in the same vertical plane. By using the arc-shaped fixing block 905 in the same vertical plane as the cam 903, it is convenient to drive the sliding plate 906 to slide up and down.

[0038] In this embodiment, one side of the top end of the sliding plate 906 is triangular, and a sliding structure is formed between one side of the sliding plate 906 and the surface of the slide bar 901. By using the sliding plate 906 with a triangular top end, it is possible to prevent solid waste from accumulating on the top end of the sliding plate 906.

[0039] Furthermore, the shape of the side view of the feed hopper 1 is an inverted isosceles trapezoid, and the bottom end of the feed hopper 1 is fixedly connected to the top end of the crushing box 4 through bolts.

By using the inclined guide plates 8, it is convenient to guide the solid waste crushed by the crushing rollers 7 and facilitate the discharging action.

[0041] Working principle and usage process of the present utility model: First, solid waste is added into the interior of the crushing box 4 through the feed hopper 1, and then the driving motor 2 is started. The crushing roller 7 slowly rotates through the speed reducer 5 to crush the solid waste. When the crushing roller 7 rotates to crush the solid waste, the crushing roller 7 and the cleaning teeth 601 rotate relative to each other. Thus, the cleaning teeth 601 can be used to remove the solid waste accidentally stuck in the gap, realizing the automatic cleaning and dredging of the crushing roller 7, avoiding affecting the subsequent crushing effect of the crushing roller 7 on the solid waste, or the cumbersome inconvenience of needing to stop the machine for dredging again;

[0042] Meanwhile, the solid waste generated by the crushing of the crushing roller 7 is guided by the material guiding plate 8 and then discharged through the discharge pipe 10. At this time, when the discharge pipe 10 is discharging, the servo motor 904 can be started to drive the cam 903 to rotate, periodically contacting the fixed block 905, causing the sliding plate 906 to slide on the surface of the slide bar 901 and stretch the fixed spring 910, and causing the anti-blocking rod 902 to descend. Then, after the cam 903 rotates away, the elastic force of the fixed spring 910 is used to make the sliding plate 906 slide to drive the anti-blocking rod 902 to rise. Thus, the dredging operation of the discharge pipe 10 can be realized through the up and down sliding of the anti-blocking rod 902, avoiding the blockage of the crushed solid waste inside the discharge pipe 10 and affecting the discharge and collection rate;

[0043] And after the crushing operation is completed, the feed hopper 1 can be disassembled, and then the fastening bolt 605 is rotated until it completely disengages from the interior of the fastening screw hole 607, and then the fixing plate 602 is pulled forcefully until it completely separates from the fixing groove 604, facilitating the maintenance or replacement of the damaged cleaning teeth 601. Meanwhile, during installation, the clamping plate 609 is snapped into the clamping groove 603, and then the fastening bolt 605 is screwed into the fastening screw hole 607. At the same time, by using the O-shaped rubber ring 606, the elastic anti-slip property between the nut of the fastening bolt 605 and the inner wall of the reserved groove 608 can be increased, avoiding the loosening of the thread of the fastening bolt 605 and affecting the firm stability of the installation of the fixing plate 602.

[0044] The above is only the preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
