A dust removal bin 29 is fixedly installed on one side of the crushing bin 1. A clamping hole 31 is provided on one side of the dust removal bin 29, and a filter screen 32 is movably sleeved inside the clamping hole 31. A load-bearing hole 30 is provided on the top surface of the dust removal bin 29, and a limiting pipe 28 is fixedly sleeved on the inner wall of the load-bearing hole 30. An exhaust fan 27 is fixedly installed on the top surface of the dust removal bin 29, and the outer wall of the air outlet of the exhaust fan 27 is fixedly sleeved on the inner wall of the load-bearing hole 30. The inner wall of the limiting tube 28 is fixedly sleeved, and the outer wall of the air inlet of the exhaust fan 27 is fixedly sleeved with a connecting tube 25. The outer wall of the connecting tube 25 has two fixing holes 26. The inner wall of the fixing hole 26 is fixedly sleeved with the outer wall of the collecting tube 24. The exhaust fan 27 is electrically connected to the PLC controller. Through the dust removal bin 29, when the staff is crushing the waste, the waste will generate a lot of dust. At this time, the staff uses the PLC controller to start the exhaust. The dust collecting bin 29 is then passed through the collecting pipe 24 and the connecting pipe 25, and the dust-carrying air passes through the filter screen 32. After the dust in the air is filtered, the dust is filtered. A load-bearing frame 34 is fixedly installed on one side of the crushing bin 1. The inner wall surface of the load-bearing frame 34 is fixedly installed with the outer circular wall surface of the driving motor 4. A collecting bin 35 is arranged on the bottom surface of the crushing bin 1. Connecting frames 22 are fixedly installed on both sides of the crushing bin 1. Placement bins 36 are arranged on both sides of the crushing bin 1. Several moving holes 38 are opened on the top surface of the screen 18. Two limiting columns 37 are fixedly installed on the bottom surface of the positioning block 9. The outer circular wall surface of the limiting column 37 is movably connected with the inner circular wall surface of the moving hole 38. A battery 40 is fixedly installed on one side of the crushing bin 1. The battery 40 is electrically connected to the driving motor 4, the servo motor 11, the exhaust fan 27 and the PLC controller respectively.

[0028] Working principle: Please refer to Figure 1-Figure 8 As shown, through the set crushing bin 1, when the staff crushes the waste, they first use the PLC controller to start the drive motor 4, and then the drive shaft of the drive motor 4 rotates to drive the two crushing rollers 3 to rotate. At this time, the staff puts a large amount of waste on the surface of the inclined frame 5, and then one side of the inclined frame 5 is an inclined surface. The waste moves downward due to its own gravity. When the waste moves to one side of the baffle 6, the waste’s own gravity will push the baffle 6 to rotate, and then the waste falls between the two crushing rollers 3 for crushing. When all the waste falls into the inside of the crushing bin 1, the baffle 6 is in a vertical state again due to gravity. At this time, when the two crushing rollers 3 crush the waste, the splashing waste will be blocked by the baffle 6, thereby protecting the safety of the staff. When the waste is crushed, blocks of different sizes will be produced. The staff uses the PLC controller to start the servo motor 11, and then the driving shaft of the servo motor 11 rotates to drive the positioning plate 12 and the connecting column 17 to rotate. As the connecting column 17 continues to rise and fall, the screen 18 is driven to shake continuously through the connecting block 14, and then the crushed waste falls on the screen 18. The smaller ones are filtered by the shaking of the screen 18 and fall on the bottom surface of the crushing bin 1. The larger waste will roll under the continuous shaking of the screen 18, and then move from the discharge hole 21 to the two sides of the crushing bin 1, so as to achieve the effect of filtering the crushed waste. At the same time, the staff continuously adds waste to the inside of the crushing bin 1 through the inclined frame 5, so as to continuously crush and classify the waste, thereby achieving the effect of blocking the splashing waste, which is convenient for protecting the health of the staff.

[0029] Through the dust removal bin 29, when the staff crushes the waste, a large amount of dust will be generated. At this time, the staff uses the PLC controller to start the exhaust fan 27, and then the exhaust fan 27 draws out the air with dust in the crushing bin 1, and then the dusty air enters the dust removal bin 29 through the collecting pipe 24 and the connecting pipe 25. The dusty air passes through the filter net 32, and the dust in the air is filtered, thereby filtering the dust.

[0030] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
