[0002] Solid waste refers to solid and semi-solid waste materials generated by human beings in production, consumption, life and other activities. In layman's terms, it is "garbage", mainly including solid particles, garbage, slag, sludge, discarded products, broken utensils, defective products, animal carcasses, spoiled food, human and animal feces, etc. Some countries also classify high-concentration liquids such as waste acid, waste alkali, waste oil, and waste organic solvents as solid waste, which are solid or semi-solid substances abandoned because they have no "utilization value". There are many types of solid waste, which can be roughly divided into three categories: industrial waste, agricultural waste and domestic waste.

[0003] In the existing solid waste detection, the extracted solid waste is generally placed in a detection test tube, the detection liquid is poured into the detection test tube, and the detection bottle is shaken for detection. However, many solid wastes are in large pieces and cannot be directly placed in the detection test tube. They need to be manually crushed using other auxiliary equipment, and then the crushed particles are extracted for detection. The whole operation is relatively complicated, resulting in low detection efficiency. Summary of the invention

The outer wall of the fixed bracket (3) is fixedly connected to a guide rod (808), and the bottom surface of one end of the crushing table (4) away from the guide frame 2 (807) is fixedly connected to a guide seat (809), and the guide seat (809) is slidably arranged on the surface of the guide rod (808). Both ends of the outer walls of both sides of the crushing table (4) are fixedly connected to spring 2 (810), and one end of the spring 2 (810) away from the crushing table (4) is fixedly connected to the outer wall of the fixed bracket (3).

4. A method for detecting harmful substances in solid waste, using the device for detecting harmful substances in solid waste as claimed in claim 3, characterized in that: The steps include: Step 1: placing the block-shaped solid waste on the middle of the top surface of the crushing table (4), and controlling and adjusting the hydraulic cylinder (702) to move the upper crushing hammer (705) up and down and the side crushing hammer (718) horizontally to crush the block-shaped solid waste; Step 2: during the crushing process, the motor 1 (801) is started, so that the movable seat 2 (805) drives the crushing table (4) to reciprocate in the horizontal direction, and the crushed pieces are discharged through the discharge hole (6) and enter the discharge hopper (9); Step three, start motor 2 (1003) to make the feed plate (1006) slide along the top surface of the discharge tray (1001), so that the crushed pieces evenly enter the multiple guide buckets (1007), and enter the detection test tube (1009) through the guide buckets (1007), take out the detection test tube (1009) and add the detection liquid into it, after shaking, extract the liquid in the detection test tube (1009) into the detector (1010) for harmful substance detection.
