[0032] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0033] like Figure 1-3 As shown, the waste glass crushing and screening device includes:

[0034] Crushing box 1;

[0035] Rotating the crushing hammer 12 disposed in the crushing box 1;

[0036] A first feeding plate 13 slidably disposed in the crushing box 1;

[0037] A first grinding roller 14 arranged in a linear array at the bottom end of the first feeding plate 13;

[0038] A second feeding plate 15 is disposed in the crushing box 1 and is driven to maintain relative motion with the first feeding plate 13;

[0039] The second grinding rollers 16 are arranged in a linear array at the top of the second feeding plate 15 , and the second grinding rollers 16 and the first grinding rollers 14 are arranged in a cross pattern.

[0040] Specifically, when the waste glass needs to be crushed, the breaker hammer 12 is driven to rotate at a high speed so that the breaker hammer 12 will smash the glass entering the crushing box 1. After the glass is broken, it will fall toward the first feeding plate 13. When the volume of the glass fragments is smaller than the aperture of the hole in the first feeding plate 13, the glass fragments will slide between the first feeding plate 13 and the second feeding plate 15. By driving the first feeding plate 13 and the second feeding plate 15 to move back and forth while maintaining relative motion, the first feeding plate 13 and the second feeding plate 15 respectively drive the first grinding roller 14 and the second grinding roller 16 to maintain relative motion. The first grinding roller 14 and the second grinding roller 16 cooperate with each other to squeeze the glass fragments, so that the glass fragments can be quickly crushed into particles of a predetermined size. Only when the glass fragments are crushed into particles of a predetermined size can the glass fragments pass through the aperture of the second feeding plate 15, so that the glass fragments passing through the second feeding plate 15 can maintain a more uniform size.

[0041] In the above embodiment, by arranging a breaker hammer 12, a first feeding plate 13, a first grinding roller 14, a second feeding plate 15 and a second grinding roller 16 in the crushing box 1, the broken glass can be conveniently crushed into particles of a specified size. The broken hammer 12 rotates to hit the waste glass into fragments, so that the glass fragments can pass through the aperture of the first feeding plate 13 and slide between the first feeding plate 13 and the second feeding plate 15. The first grinding roller 14 installed on the first feeding plate 13 and the second grinding roller 16 installed on the second feeding plate 15 are arranged in a cross manner, so that the first feeding plate 13 When reciprocating in the direction opposite to the second feeding plate 15, the first grinding roller 14 and the second grinding roller 16 can squeeze the glass fragments between the first feeding plate 13 and the second feeding plate 15, so that the glass fragments can be quickly crushed into particles of a predetermined size. When the glass fragments are crushed into a predetermined size, the glass fragment particles can pass through the holes on the first feeding plate 13, so that the size of the crushed glass fragment particles is more uniform, which not only solves the problem of low crushing efficiency, but also improves the uniformity of the glass particles, and further improves the recycling efficiency of waste glass.

[0042] As an embodiment further provided by the present invention, symmetrically arranged chutes 6 are provided in the crushing box 1 , a first feeding plate 13 is movably connected in the chute 6 , and a second feeding plate 15 is movably connected in another adjacent chute 6 .

[0043] Specifically, the first feeding plate 13 and the second feeding plate 15 are respectively installed in two symmetrically arranged chute 6, so that the first feeding plate 13 and the second feeding plate 15 can slide stably in the crushing box 1 when being driven.

[0044] As another embodiment further provided by the present invention, a fixing frame 10 is movably installed in the slide groove 6, the side wall of the fixing frame 10 is fixedly connected to the first feeding plate 13, and the side wall of another fixing frame 10 is fixedly connected to the second feeding plate 15, and tooth buckles 9 are symmetrically arranged on the side walls of the fixing frame 10.

[0045] Furthermore, a rotating block 7 is movably installed in the sliding groove 6 , and the side wall of the rotating block 7 is provided with tooth columns 8 in a circumferential array, and the tooth columns 8 are engaged with the tooth buckles 9.

[0046] Specifically, by driving the rotating block 7 to rotate, the rotating block 7 drives multiple gear columns 8 to rotate simultaneously, and the gear columns 8 are engaged with the gear buckles 9 installed on the fixed frame 10, so that the gear columns 8 and the gear buckles 9 cooperate with each other, thereby driving the fixed frame 10 to move back and forth, and the fixed frame 10 drives the first feeding plate 13 and the second feeding plate 15 to move back and forth, so that the unloading efficiency is higher during the movement of the first feeding plate 13 and the second feeding plate 15.

[0047] As another embodiment further provided by the present invention, a second motor 11 is symmetrically provided on the side wall of the crushing box 1 , and an output end of the second motor 11 is fixedly connected to the rotating block 7 .

[0048] Specifically, two symmetrically arranged motors drive different rotating blocks 7 to rotate in different directions, so that the rotating blocks 7 can drive the fixed frames 10 installed in the two slide grooves 6 to maintain relative movement, so that the fixed frames 10 can drive the first feeding plate 13 and the second feeding plate 15 to maintain relative movement while moving back and forth, and the first feeding plate 13 and the second feeding plate 15 respectively drive the first grinding roller 14 and the second grinding roller 16 to move, so that the first grinding roller 14 and the second grinding roller 16 can crush the glass fragments during the relative movement, so that the glass fragments can be crushed into particles of predetermined size.

[0049] As another embodiment further provided by the present invention, a first motor 5 is fixedly mounted on the side wall of the crushing box 1 , and an output end of the first motor 5 is fixedly connected to the crushing hammer 12 .

[0050] Specifically, the first motor 5 drives the breaker hammer 12 to rotate, so that the breaker hammer 12 can break the waste glass entering the crushing box 1 .

[0051] As another embodiment further provided by the present invention, a torsion spring 17 is fixedly mounted on the side wall of the crushing box 1 , and a screening plate 4 is fixedly mounted on the end surface of the torsion spring 17 .

[0052] Specifically, when glass fragments of a predetermined size fall off the crushing box 1 along the holes of the second feed plate 15, the glass fragments will fall onto the screening plate 4, and the glass fragments will be screened by the screening plate 4, thereby improving the uniformity of the glass fragments and increasing the efficiency of melting. The torsion spring 17 provides elastic force to the screening plate 4, so that when the glass fragments fall onto the screening plate 4, the screening plate 4 vibrates, and the vibration generated by the screening plate 4 enables the screening plate 4 to quickly screen out large glass particles and shake them off to the outside of the screening plate 4, thereby preventing large glass particles from clogging the filter holes of the screening plate 4.

[0053] As another embodiment further provided by the present invention, the bottom end of the crushing box 1 is provided with support rods 2 in a linear array, and a material receiving box 3 is fixedly mounted on the support rods 2.

[0054] Specifically, the receiving box 3 is fixed to the bottom of the screening plate 4 by the support rod 2 installed at the bottom of the crushing box 1, so that the glass fragment particles screened by the screening plate 4 can fall into the receiving box 3 for collection, thereby making the collection effect of the glass fragment particles higher.

[0055] Working principle: The first motor 5 drives the breaker hammer 12 to rotate at a high speed, so that the breaker hammer 12 will break the glass entering the crushing box 1, and the broken glass fragments fall toward the first feeding plate 13. When the volume of the glass fragments is lower than the aperture of the hole of the first feeding plate 13, the glass fragments will fall between the first feeding plate 13 and the second feeding plate 15. When the glass fragments fall between the first feeding plate 13 and the second feeding plate 15, the two motors drive the rotating block 7 to rotate in different directions respectively, so that the rotating block 7 engages with the tooth column 8 and the tooth buckle 9, thereby driving the fixing frame 10 installed in the two slide grooves 6 to move relative to each other and reciprocate at the same time. The first feeding plate 13 and the second feeding plate 15 respectively drive the first grinding roller 14 and the second grinding roller 16 to move, so that the first grinding roller 14 and the second grinding roller 16 can crush the glass fragments during the relative movement, so that the glass fragments can be crushed into particles of a predetermined size. When the glass fragments are broken into particles of a predetermined size, the glass fragments will slide along the holes of the second feeding plate 15 toward the screening plate 4, and the glass fragment particles will be screened again by the screening plate 4, so that the uniformity of the glass fragment particles is higher. The screening glass fragment particles are collected by installing a collecting box 3 on the support rod 2, so that the glass fragment particles can be quickly collected.

[0056] The above description is merely illustrative of certain exemplary embodiments of the present invention. It goes without saying that those skilled in the art will be able to modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
