DETAILED DESCRIPTION

[0021] The specific embodiments of the utility model are described in detail below with reference to the drawings.

[0022] Embodiment:

[0023] The specific embodiments of the utility model are described in detail below with reference to the drawings. Figure 1 It mainly includes rack 1, rack 1 is equipped with crushing box 2, the top of crushing box 2 is equipped with feeding hopper 3, the left end of feeding hopper 3 is feed inlet, material is thrown into feeding hopper 3 from feed inlet, and then falls into crushing box 2.

[0024] Crushing box 2 is equipped with crushing knife and screen 4 located below crushing knife, Figure 1 Rack 1 is equipped with crushing motor 5, crushing motor 5 is connected with crushing knife through pulley assembly 6, and crushing motor 5 drives crushing knife to rotate, breaks material, which is prior art, and screen 4 is used for screening broken material.

[0025] The lower portion of rack 1 is equipped with suction fan 7 connected with the bottom of crushing box 2, and broken material is sucked out by suction fan 7 through screen 4.

[0026] Refer to Figures 1 to 5 Crushing box 2 includes rotatably connected upper box 201 and lower box 202, feeding hopper 3 is fixedly connected to the top of upper box 201, crushing knife and screen 4 are installed in lower box 202, the edge of screen 4 is fitted with the inner wall of lower box 202, and broken material leakage is avoided.

[0027] The specific connection structure of upper box 201 and lower box 202 is that the left side of lower box 202 is rotatably connected with a rotating shaft, the left side of upper box 201 is fixedly installed on the rotating shaft, and the rear side of lower box 202 is provided with a turnover motor connected with the driving rotating shaft. The turnover motor drives the rotating shaft to rotate and drives upper box 201 to overturn.

[0028] A flip plate 8 is rotatably mounted on the right side of the lower housing 202. A drive shaft 9 is connected to the bottom of the flip plate 8. A pressing motor 10 and a bearing seat 11 are respectively connected to both ends of the drive shaft 9. The pressing motor 10 and the bearing seat 11 are fixedly mounted on the right side of the lower housing 202. Several equally spaced pressing blocks 12 are connected to the flip plate 8. The longitudinal section of the pressing blocks 12 is T-shaped. The right side of the upper housing 201 is provided with several slots 14 that correspond one-to-one with each pressing block 12. The slots 14 match the shape of the pressing blocks 12. The pressing blocks 12 can be pressed into the slots 14 to achieve the pressing of the upper and lower housings. After the pressing blocks 12 are pressed in, the height of the pressing blocks 12 is less than the depth of the slots 14.

[0029] A detection plate 13 is also elastically mounted on the upper surface of the lower housing 202. The detection plate 13 can be installed by a spring, and a sensor is provided at the bottom of the detection plate 13 to detect whether the upper and lower housings are pressed together.
