Figure 1-2, including a box body 1, a fixed jaw pressure plate 4, a movable jaw seat 5 and a movable jaw pressure plate 11, the fixed jaw seats 3 are fixedly installed on both sides of the box body 1 through the bracket 2, the two fixed jaw seats 3 are fixedly installed with the fixed jaw pressure plates 4, the movable jaw seat 5 is installed between the two fixed jaw seats 3, and the movable jaw pressure plates 11 are fixedly installed on both sides of the movable jaw seat 5. A first shaft hole 502 is opened on the lower middle part of the movable jaw seat 5, and a first shaft rod 8 is rotatably installed in the first shaft hole 502. The end of the first shaft rod 8 is fixedly connected to the side wall of the box body 1, and the movable jaw seat 5 swings back and forth around the first shaft rod 8; An arc-shaped slide groove 10 is provided on the side wall of the box body 1, and a second axial hole 503 is provided on the middle top of the movable jaw seat 5. A second shaft rod 9 is fixedly installed in the second axial hole 503, and the end of the second shaft rod 9 is slidably installed in the arc-shaped slide groove 10. By setting two inclined fixed jaw pressure plates 4 and a reciprocating movable jaw seat 5, solid phenolic resin can be crushed. During the crushing process, as the movable jaw pressure plate 11 continuously approaches the fixed jaw pressure plate 4, the gap between the movable jaw pressure plate 11 and the fixed jaw pressure plate 4 gradually becomes narrower at the top and wider at the bottom, and an oblique downward force is generated, thereby reducing the upward flying of embedded waste fragments to improve safety.

[0025] The two fixed jaw pressure plates 4 are symmetrically arranged about the center line of the box body 1, and the distance between the working surfaces of the two fixed jaw pressure plates 4 gradually increases from the bottom to the top; the two movable jaw pressure plates 11 are symmetrically arranged about the center line of the movable jaw seat 5, and the distance between the working surfaces of the two movable jaw pressure plates 11 gradually increases from the bottom to the top.

[0026] Two parallel crushing rollers 13 are provided directly below the two fixed jaw pressure plates 4. A third shaft 12 is coaxially fixedly mounted on the crushing rollers 13. The other end of the third shaft 12 is rotatably connected to the box body 1. A silo 14 is installed at the inner bottom of the box body 1.

[0027] like Figure 4 、 Figure 8 As shown, a silencer assembly 6 is installed on the movable jaw seat 5, and the silencer assembly 6 includes a silencer hole 601 that penetrates the side wall of the movable jaw pressure plate 11. The silencer hole 601 is perpendicular to the working surface of the movable jaw pressure plate 11. One end of the silencer hole 601 penetrates into the movable jaw seat 5. The cross-sectional shape of the silencer hole 601 is hexagonal. Silencer cotton 602 is installed on the side wall of the silencer hole 601. By setting the silencer assembly 6, the noise during crushing can be reduced.

[0028] like Figure 4 、 Figure 9As shown, a mounting groove 501 is provided in the movable jaw seat 5, and the dust reduction assembly 7 is installed in the mounting groove 501. The dust reduction assembly 7 includes a pendulum 701, an air bag 702 and an air guide tube 703. The top of the pendulum 701 is hinged to the side wall of the mounting groove 501, and the air bags 702 are installed on both sides of the bottom of the pendulum 701. The other side of the air bag 702 is connected to the inner wall of the mounting groove 501, and one end of the air guide tube 703 is in fluid communication with the air bag 702. The other end of the air guide tube 703 is in fluid communication with the silencer hole 601. By setting the dust reduction component 7, the dust reduction component 7 can swing with the swing of the movable jaw seat 5, squeezing the air bag 702 on one side, and the air is blown out obliquely downward through the silencer hole 601, thereby suppressing the dust generated during crushing, and can dredge the silencer hole 601 to avoid clogging of the silencer hole 601. At the same time, the air bag 702 on the other side is stretched, and air is sucked out at an oblique upward angle to suck in the scattered dust, thereby further reducing the scattered dust.

[0029] Working process: connect the second shaft 9 to the external power, so that the movable jaw seat 5 can swing back and forth around the first shaft 8; connect the two crushing rollers 13 to the rotating power, so that the two crushing rollers 13 can rotate inward synchronously;

[0030] The waste is put into the box 1, and as the movable jaw seat 5 swings back and forth, the movable jaw pressure plate 11 is used to push the waste, and the waste is squeezed and crushed between the fixed jaw pressure plates 4. Synchronously, due to the swing of the movable jaw seat 5, the pendulum 701 installed inside it swings along with it, as shown in FIG. Figure 2 As shown, when the movable jaw seat 5 swings to the right, the pendulum 701 swings and squeezes the right airbag 702, so that the gas inside it is blown out through the silencer hole 601, which can prevent the silencer hole 601 from being blocked and can also blow air diagonally downward to avoid dust flying. The airbag 702 on the left is stretched, and the silencer hole 601 on the left is facing diagonally upward to suck the gas above, thereby further avoiding dust flying.

Those skilled in the art will readily appreciate that other variations or modifications based on the above descriptions are possible. It is not necessary and impossible to enumerate all implementation methods here. Obvious variations or modifications arising therefrom remain within the scope of protection of the claims of this patent application.
