[0041] All electrical equipment in this solution are powered by an external power supply.

[0042] Working principle: When this kind of efficient construction crushing device is used, the staff puts the waste into the box 1, and then starts the crushing mechanism 2 to break the waste into pieces, and then drops it onto the screening mechanism 3. The large particles of waste roll into the inside of the conveying cylinder 51 through the vibration of the screening mechanism 3. The spiral blades 53 are driven by the conveying mechanism 5 to rise, and the waste is sent into the box 1 again through the conveying mechanism 5 for secondary crushing. When the waste enters the box 1, the staff starts the motor 23, and the motor 23 drives the gear 22, another gear 22 that meshes with each other rotates, and the two crushing rollers 21 rotate relative to each other inside the box body 1 to squeeze the crushing rollers 21, so that the waste entering the box body 1 is crushed, thereby achieving a crushing effect. When the crushed waste falls to the screening mechanism 3, the staff starts the vibration motor 36. Due to the vibration of the vibration motor 36 itself, the vibration motor 36 drives the fixed frame 32 and the spring 33 to vibrate. Under the tension of the spring 33, the screening net 35 in the vibration frame 34 vibrates together, thereby screening out waste of the same size, and passing through the installed motor door 3 1. When replacing the screening net 35, it is prevented that the vibration motor 36 is blocked, and it is also convenient to take it when the vibration motor 36 is damaged. A large amount of dust and smoke will be generated during the crushing process. The staff starts the exhaust fan 44 to let the dust and smoke inside the box body 1 enter the inside of the L-shaped ventilation box 41 through the ventilation port, and then draw it into the inside of the dust box 42 through the L-shaped ventilation box 41. The filter net 45 inside the ventilation port prevents granular waste from entering the L-shaped ventilation box 41 through the ventilation port. The wind entering the dust box 42 is discharged through the air outlet slot, and under the action of the dust-proof net 46 , so that the dust in the wind is blocked, and the blocked dust will fall into the inside of the drawer 1 48, so that the dust is collected. After the crushing is completed, the handle 3 12 is manually held and pulled to make the drawer 2 11 slide inside the drawer slot, which is used to open the drawer 2 11, so that the waste is collected in a centralized manner. The installed hopper 6 is used to prevent accidental dispersion when the waste is put in. The staff holds the handle 8 to make the cover plate 7 contact with the hopper 6, so that the rubber block 9 seals the hopper 6 to prevent the staff from inhaling a large amount of smoke and dust generated during the crushing, causing harm to the human body.
