[0011] In summary, the beneficial effects of this application are:

[0012] 1. By setting crushing rollers and screening plates, hazardous waste is input into the box through the feed hopper. First, the crushing roller is driven by electricity in the rear chassis to crush it, which is beneficial to the subsequent hazardous waste processing. The crushed hazardous waste is then introduced onto the screening plate through the guide inclined block. Under the cooperation of the material's own gravity and the micro vibrator, the solid waste that can be screened falls to the bottom of the box, and the unscreened solid waste stays on the screening plate. The cylinder is started, and the cylinder drives the push plate to push the unscreened hazardous waste to the opening and send it into the collection box. At the same time, the brush at the bottom of the push plate cleans the screening plate, which improves the efficiency of the screening plate and improves the practical performance. The hazardous waste stored in the collection box is introduced into the feed hopper again through the conveying pipeline and the electric pump, so that the above steps are performed again to pre-process it, so as to realize the recycling of hazardous waste materials and improve the processing quality of pre-hazardous waste pretreatment.

[0013] 2. By setting up a spiral dragon, the sieved hazardous waste is deposited at the bottom of the box. The servo motor is started through the control panel. The servo motor drives the spiral dragon to rotate forward or reverse, stirs the sieved hazardous waste and transports it to the discharge port. The staff can place a material transport cart under the discharge port in advance. After opening the valve, the sieved hazardous waste is directly poured into the material transport cart under the stirring of the spiral dragon, which effectively solves the problem of accumulation of crushed hazardous waste in the storage area. It can be quickly output, improve the efficiency of hazardous waste pretreatment and processing, and avoid the need for manual discharge, provide safety performance, and effectively avoid harm to personnel health.
