The telescopic end of the hydraulic cylinder 21 will drive the extrusion plate 22 to move towards each other. The blanking plate 24 is fixedly installed on the top of the extrusion plate 22. The extrusion plate 22 drives the blanking plate 24 to move towards each other. The blanking plate 24 is tilted. The baffle 25 is fixedly installed on the top of the blanking plate 24. The blanking plate 24 drives the baffle 25 to move towards each other. The extrusion plate 22 moves towards the middle to pre-process the glass products. Gathering towards the middle can crush the glass products to a greater extent. The inclined blanking plate 24 can make the glass products crushed smoothly. The baffle 25 can prevent the glass products from falling to the back of the extrusion plate 22 during the operation of the extrusion plate 22. By setting the extrusion plate 22, the discarded glass products can be effectively pre-processed and crushed. Driven by the hydraulic cylinder 21, the two extrusion plates 22 move towards each other, gradually gathering the glass products towards the middle, thereby achieving preliminary crushing of the glass.

[0027] The crushing device 2 also includes a slide bar 26, a kneading plate 27, a triangular block 28, a resistance block 29 and a spring 210. The slide bar 26 is slidably mounted on the inner wall of the slide groove of the extrusion plate 22. When the extrusion plates 22 move toward each other, the extrusion plates 22 drive the slide bar 26 to move toward each other. The kneading plate 27 is fixedly mounted on the outer wall opposite to the slide bar 26. The kneading plate 27 is slidably mounted on the outer wall of the extrusion plate 22. The triangular block 28 is fixedly mounted on the left end of the slide bar 26. The slide bar 26 drives the kneading plate 27 and the triangular block 28 to move toward each other. The resistance block 29 is fixedly mounted on the inner wall of the fuselage 1 near the triangular block 28. The resistance block 29 is triangularly arranged, and the number of the resistance blocks 29 is several, and the resistance blocks 29 are located at the triangular blocks 28. The triangular block 28 abuts against the abutment block 29 on the inner wall of the body 1, and the spring 210 is arranged between the slide bar 26 and the inner wall of the slide groove of the extrusion plate 22, so that the triangular block 28 drives the slide bar 26 to slide in the direction of the spring 210, and the slide bar 26 drives the rubbing plate 27 to slide in the direction of the spring 210. After the abutment is released, the spring 210 drives the slide bar 26 to reset, and the rubbing plate 27 can slide left and right during the process of moving toward each other, so that the glass can be subjected to multi-directional friction while being squeezed, thereby further improving the crushing efficiency and uniformity, not only improving the crushing efficiency of glass products, but also ensuring the uniformity of the crushing process, and avoiding the generation of large pieces of glass.

[0028] When the present embodiment is working, when the discarded glass products need to be recycled and disposed, the glass products are poured into the interior of the body 1, and the glass products fall on the top of the limiting rod 23, and the hydraulic cylinder 21 is started. The telescopic end of the hydraulic cylinder 21 drives the squeeze plate 22 to move toward each other, and the squeeze plate 22 drives the blanking plate 24 to move toward each other, and the blanking plate 24 drives the baffle 25 to move toward each other, and the squeeze plate 22 moves toward the middle to pre-treat the glass products. Gathering toward the middle can crush the glass products to a greater extent. The inclined blanking plate 24 can make the glass products crushed smoothly. The baffle 25 can prevent the glass products from falling to the back of the squeeze plate 22 during the operation of the squeeze plate 22. By setting the squeeze plate 22, the discarded glass products can be effectively pre-treated and crushed. Driven by the hydraulic cylinder 21, the two squeeze plates 22 move toward each other, gradually gather the glass products toward the middle, so as to achieve the initial crushing of the glass.

[0029] When the extrusion plates 22 move toward each other, the extrusion plates 22 drive the slide bars 26 to move toward each other, and the slide bars 26 drive the rubbing plates 27 and the triangular blocks 28 to move toward each other, and the triangular blocks 28 abut against the abutment blocks 29 on the inner wall of the fuselage 1, so that the triangular blocks 28 drive the slide bars 26 to slide in the direction of the spring 210, and the slide bars 26 drive the rubbing plates 27 to slide in the direction of the spring 210. After the abutment is released, the spring 210 drives the slide bars 26 to return to their original positions, and the rubbing plates 27 can also slide left and right during the process of moving toward each other, so that the glass can be subjected to multi-directional friction while being squeezed, thereby further improving the crushing efficiency and uniformity, which not only improves the crushing efficiency of glass products, but also ensures the uniformity of the crushing process and avoids the generation of large pieces of glass.

Broken glass products will fall to the top of the sub-screening plate 33 through the gap between the limiting rods 23. When the extrusion plates 22 move toward each other, the fixed plates 34 are fixedly mounted on the bottom ends of the extrusion plates 22. The extrusion plates 22 drive the fixed plates 34 to move toward each other. The grinding roller 35 is rotatably mounted on the inner wall of the fixed plate 34 through a rotating rod. The grinding roller 35 contacts the top surface of the sub-screening plate 33. The fixed plate 34 drives the grinding roller 35 to move toward each other.

The grinding roller 35 contacts the triangular block 36 on the top of the mounting frame 32, so that the triangular block 36 drives the mounting frame 32 to move downward on the inner wall of the sliding frame 31, and the mounting frame 32 drives the sub-screen plate 33 to move downward. The spring piece 37 is arranged between the sliding frame 31 and the mounting frame 32. The spring piece 37 is elastically arranged and then reset by the spring piece 37 at the bottom of the mounting frame 32.

When the mounting frame 32 moves downward, the mounting frame 32 drives the lower pressure rod 311 to move downward. The lower pressure rod 311 contacts the turning bar 310 on the outer wall of the L-shaped fixed rod 38, causing the turning bar 310 to rotate counterclockwise with the rotating shaft 39 as the center. The knocking ball 312 is fixedly installed on the top of the turning bar 310 away from the lower pressure rod 311. The knocking ball 312 is located on the movement trajectory of the sub-screen plate 33. The knocking ball 312 at the other end of the turning bar 310 will knock the bottom surface of the sub-screen plate 33 upward. The periodic knocking of the knocking ball 312 promotes the redistribution of glass particles on the sub-screen plate 33, avoids particle aggregation and blockage, further improves the uniformity and accuracy of the sub-screening, extends the service life of the equipment, and reduces maintenance requirements.

[0032] When the present embodiment is working, the broken glass products will fall to the top of the sub-screen plate 33 through the gap between the limiting rods 23. When the extrusion plates 22 move toward each other, the extrusion plates 22 drive the fixed plates 34 to move toward each other, and the fixed plates 34 drive the grinding rollers 35 to move toward each other.
