The telescopic end pushes the blanking plate 303 to move upward. When the blanking plate 303 moves upward, it will contact the spherical surface 2041 of the vertical rod 204 and push the vertical rod 204 to move upward. The side plate 203 and the sealing door 2 are pushed upward by the vertical rod 204 to expose the feed port 103 until the blanking plate 303 moves to the feed port 103. Then the telescopic end of the first hydraulic cylinder 301 reaches its longest end, and the telescopic end of the second hydraulic cylinder 302 continues to extend, and moves along the slide rail 3031 through the connected movable seat 304, so that the blanking plate 303 is tilted, and the solid waste is sent into the crushing chamber 101 through the feed port 103. Then the sealing door 2 follows the downward movement of the blanking plate 303 to reset and reseal the feed port 103. At this time, the two crushing rollers 702 rotate under the action of the driving source 706 to crush the incoming solid waste, and at the same time, the dust suction component 4 works to suck the dust that falls during and after the crushing process, so that the dust enters the collection box 104, and the crushed material will fall on the filter screen 5, and the remaining small particles of dust will fall to the bottom of the filter chamber 102 through the filter screen 5, and the crushed material will be discharged from the discharge port 1021 along the filter screen 5.

At the same time, the crushing roller 702 can be pulled out of the processing shell 1 for easy maintenance and replacement.

[0026] When the sealing door 2 is lifted up by the upwardly moved blanking plate 303, the two limiting grooves 201 will move along the slide plate 1031, so that the slide plate 1031 squeezes the return spring 202, which can prevent the sealing door 2 from being separated from the processing shell 1, and at the same time make the sealing door 2 close more tightly; During the crushing process, the negative pressure pump 404 in the dust suction component 4 works, so that negative pressure is formed inside the collection box 104, and suction is generated at the dust suction port 401 through the two dust suction pipes 402 to suck the generated dust, so that the dust enters the collection box 104 through the dust suction pipes 402 and adheres to the cloth bag 403, wherein the protective net 4011 can prevent solid waste from entering the dust suction port 401.

[0028] When it is necessary to extract the crushing roller 702, the staff member holds the handle 7041 to rotate the turntable 704, and the turntable 704 rotates on the fixed plate 7 along the annular slider 705 through the slide groove 7042. The rotating turntable 704 drives the shaft 801 to rotate, and the driving sprocket 8011 rotates through the shaft 801. The driving sprocket 8011 drives the two driven sprockets 8021 to rotate through the transmission chain 803. The two driven sprockets 8021 transmit the rotational force to the first bevel gear 8022 through the transmission shaft 802. The rotating first bevel gear 8022 will drive the meshing second bevel gear 8041 to rotate, and the rotation of the second bevel gear 8041 will cause the threaded rod 804 to rotate, thereby causing the square sleeve 805 to move along the penetrating cavity wall following the rotation of the threaded rod 804. The moving square sleeve 805 will move out of the fixing groove 1071 to cancel the fixation between the fixing plate 7 and the mounting groove 107, and then the fixing plate 7 and the mounting plate 701 can be pulled to move by the handle 7041, thereby completing the removal of the crushing roller 702.

[0029] The working principle of the present invention is: When solid waste is processed for resource recovery, it needs to be crushed first. First, the staff piles the solid waste on the blanking plate 303, and then starts the first hydraulic cylinder 301 and the second hydraulic cylinder 302 through the control panel 105. The telescopic end pushes the blanking plate 303 upward. When the blanking plate 303 moves upward, it will contact the spherical surface 2041 of the vertical rod 204 and push the vertical rod 204 to move upward. The side plate 203 and the sealing door 2 are pushed upward by the vertical rod 204, and the two limiting grooves 201 will move along the slide plate 1031, so that The slide plate 1031 squeezes the return spring 202 to expose the feed port 103 until the feed plate 303 moves to the feed port 103, and then the telescopic end of the first hydraulic cylinder 301 reaches its longest position, while the telescopic end of the second hydraulic cylinder 302 continues to extend, and moves along the slide rail 3031 through the connected movable seat 304, so that the feed plate 303 is tilted, and the solid waste is sent into the crushing chamber 101 through the feed port 103, and then the sealing door 2 follows the downward movement of the feed plate 303 to reset and reseal the feed port 103; At this time, the two crushing rollers 702 rotate under the action of the driving source 706 to crush the incoming solid waste, and at the same time, the negative pressure pump 404 works to form a negative pressure inside the collection box 104, and the two dust suction pipes 402 generate suction at the dust suction port 401 to suck the generated dust, so that the dust enters the collection box 104 through the dust suction pipes 402 and adheres to the cloth bag 403, and the crushed material will fall on the filter screen 5, and the remaining small particles of dust will fall to the bottom of the filter cavity 102 through the filter screen 5, and the crushed material will be discharged from the discharge port 1021 along the filter screen 5. When cleaning is needed, by starting the fixed motor 603, its output end drives the connecting shaft 601 to rotate, and the connecting shaft 601 drives the push plate 6 to move along the bottom of the cavity, pushing the accumulated dust to move and discharge it when passing through the discharge slot 1022; When the crushing roller 702 needs to be maintained after the crushing is completed, the staff member holds the handle 7041 to rotate the turntable 704, and the turntable 704 rotates on the fixed plate 7 along the annular slider 705 through the slide groove 7042. The rotating turntable 704 drives the shaft 801 to rotate, and the driving sprocket 8011 rotates through the shaft 801. The driving sprocket 8011 drives the two driven sprockets 8021 to rotate through the transmission chain 803. The two driven sprockets 8021 transmit the rotational force to the first bevel gear through the transmission shaft 802 On 8022, the rotating first bevel gear 8022 will drive the meshing second bevel gear 8041 to rotate, and the rotation of the second bevel gear 8041 will cause the threaded rod 804 to rotate, thereby causing the square sleeve 805 to move along the penetrating cavity wall following the rotation of the threaded rod 804, and the moving square sleeve 805 will move out of the fixing groove 1071 to cancel the fixation between the fixing plate 7 and the mounting groove 107, and then the fixing plate 7 and the mounting plate 701 can be pulled to move through the handle 7041 to complete the removal of the crushing roller 702.
