[0041] In order to solve the problems of poor sealing and serious dust pollution of the traditional crushing equipment, with reference to Figures 1-4 、 Figure 6 and Figure 9As shown, the dust removal unit 8 includes a dust removal shell 81, a negative pressure pump 89, and a filter screen cylinder 83. The dust removal shell 81 is fixedly installed at the top end of the feed shell 6. The filter screen cylinder 83 is installed on the inner wall of the top side of the dust removal shell 81. The negative pressure pump 89 is installed at the top end of the dust removal shell 81. A switch assembly 82 is installed at the bottom end of the dust removal shell 81 to control the communication between the dust removal shell 81 and the feed shell 6. A dust suction pipe 86 is fixedly connected to the side surface of the dust removal shell 81. A dust suction cover 87 is fixedly connected to the end of the dust suction pipe 86. The dust suction cover 87 is fixedly connected to the side surface of the crushing shell 5. An intercepting filter screen 88 is fixedly installed on the inner wall of the dust suction cover 87. The negative pressure pump 89 generates a vacuum suction force. Dust enters the dust removal shell 81 through the dust suction cover 87 and the dust suction pipe 86. The intercepting filter screen 88 installed in the dust suction cover 87 can block large particles from entering the dust suction pipe 86, preventing the dust suction pipe 86 from being blocked. The dust suction pipe 86 is unobstructed. The honeycomb structure of the filter screen cylinder 83 realizes gas-solid separation. The filter screen cylinder 83 filters dust, which adheres to the outside of the filter screen cylinder. Clean air is discharged from the negative pressure pump 89. The collected impurities fall into the dust removal shell 81. The switch assembly 82 is opened to facilitate the adsorbed dust to enter the feed shell 6 again for recycling. This reduces dust pollution of the surrounding environment, realizes the reuse of dust, avoids waste, and saves costs. Reference Figure 1 As shown, the switch assembly 82 includes an electric push rod 821, a push seat 822, and a blocking plate 823. The electric push rod 821 is fixedly installed on the top side surface of the feed shell 6. The output end of the electric push rod 821 is fixedly connected with the push seat 822. The side surface of the push seat 822 is fixedly connected with the blocking plate 823. The blocking plate 823 is slidingly connected to the bottom end side surface of the dust removal shell 81.

[0042] In use, the electric push rod 821 is started to work. The electric push rod 821 pushes the fixedly connected blocking plate 823 to move. The blocking plate 823 pushes the fixedly connected push seat 822 to move. The push seat 822 adjusts the sliding of the blocking plate 823 to facilitate the opening and closing of the bottom end of the dust removal shell 81, and facilitates the dust to be discharged into the dust removal shell 81 for reuse.

[0043] A gas cylinder 84 is installed on the top side of the dust removal shell 81. A scraping ring 85 is fixedly connected to the output end of the gas cylinder 84. The scraping ring 85 is sleeved on the surface of the filter screen cylinder 83. The inner wall of the scraping ring 85 is attached to the outer side surface of the filter screen cylinder 83. The gas cylinder 84 drives the scraping ring 85 to slide along the filter screen cylinder 83. The scraping ring 85 slides up and down along the filter screen cylinder to scrape off the adhered dust, facilitating the dust to be discharged into the dust removal shell 81 for storage.

[0044] The end of the dust suction pipe 86 connected with the dust removal shell 81 is provided with an anti-backflow part 810, which comprises a fixing cylinder 8101, an elastic spring 8102, a guide column 8103, an anti-backflow plate 8104 and a fixing strip 8105. The fixing cylinder 8101 is fixedly connected to the inner wall of the end of the dust suction pipe 86 through the fixing strip 8105. The elastic spring 8102 is installed in the inner cavity of the fixing cylinder 8101. The end of the elastic spring 8102 is attached to the anti-backflow plate 8104. The anti-backflow plate 8104 is used to seal the end of the dust suction pipe 86. The guide column 8103 fixedly connected to the anti-backflow plate 8104 is connected to the inner cavity of the elastic spring 8102.

[0045] In use, when the negative pressure pump 89 is started, a negative pressure is generated in the dust removal shell 81. The pressure of the airflow overcomes the elastic force of the elastic spring 8102, pushes the anti-backflow plate 8104 to move away from the end of the dust suction pipe 86, and separates the anti-backflow plate 8104 from the inner wall of the end of the dust suction pipe 86 to form a gap. Dust and airflow can pass through the gap into the dust removal shell 81 to complete normal dust suction. At this time, the guide column 8103 moves synchronously with the anti-backflow plate 8104 and slides along the inner cavity of the elastic spring 8102 to ensure that the anti-backflow plate 8104 moves stably without deviation. When the negative pressure pump 89 is turned off and the negative pressure in the dust removal shell 81 disappears, even if a local positive pressure is formed due to the continuous generation of dust in the crushing shell 5, the elastic spring 8102 loses the resistance of the airflow pressure and naturally resets to push the anti-backflow plate 8104 to move towards the end of the dust suction pipe 86. Finally, the anti-backflow plate 8104 is tightly attached to the inner wall of the end of the dust suction pipe 86 to completely block the passage of the dust suction pipe 86, preventing dust or airflow from entering the dust removal shell 81 through the dust suction pipe 86 in the opposite direction and preventing dust from flowing back into the dust suction pipe 86.

The connecting column 93 is fixedly connected to the top side of the control plate 92. The guide plate 95 is fixedly connected to the top end of the connecting column 93. The side plate 94 is fixedly installed on the bottom end side surface of the guide plate 95. The side plate 94 is placed in parallel with the control plate 92. In the buffering of the material, the guide plate 95 drives the side plate 94 fixedly connected to the side surface to attach to the discharge plate 12. The guide plate 95 is used to block the discharge of the crushed material. The sealed shell 4 is used for storing the material. In the discharge of the material, the control plate 92 and the feeding plate installed on one side of the discharge port of the sealed shell 4 are on the same inclined surface. The continuous inclined surface channel facilitates the discharge of the material. The material stored in the sealed shell 4 is lifted and discharged along the discharge plate 12. The guide plate 95 is used to guide the discharge of the screened material by the screen plate 11 at this time.

[0047] In this embodiment, under the action of the hydraulic cylinder 91, the hydraulic cylinder 91 pushes the fixedly connected control plate 92 to move, the control plate 92 drives the fixedly connected guide plate 95 to move through the connecting column 93, the guide plate 95 drives the fixedly connected side plate 94 to be attached to the blanking plate 12, the already screened material in the sealing shell 4 is blocked from being discharged from the discharge port, the sealing shell 4 becomes a material buffer cavity, and the crushed material is temporarily stored in the sealing shell 4; in the discharging process, the output end of the hydraulic cylinder 91 at the bottom side of the base 1 pushes the control plate 92 upwards, the control plate 92 drives the guide plate 95 to rise synchronously through the connecting column 93, and the control plate 92 and the blanking plate 12 are on the same inclined plane, so that the temporarily stored material can be conveniently discharged along the blanking plate 12.
