[0043] Working principle: In this embodiment, the plate chain elevator 11 and the belt conveyor 12 are basically consistent with the existing structure. The difference is that in this embodiment, a crushing device is arranged below the discharge hopper 8, and the bottom of the crushing device is connected to the inlet end of the plate chain elevator 11. The solid waste material can be crushed well by the crushing device to facilitate transportation. The plate chain elevator 11, the belt conveyor 12 and the crushing device are closed by the first interface box 13, the second interface box 14 and the two groups of shells, so that dust can be prevented from escaping during the transportation process, effectively improving the working environment at the work site. When the feeding vehicle passes by, the magnetic field above the geomagnetic induction module 9 changes and generates a signal. The signal is used to control the air curtain device 7 and the electromagnetic valve 25, so as to start the dust collection and air curtain isolation during unloading, and stop the device when not unloading, which plays a good energy-saving role. The start switch of the negative pressure pump 18 is controlled by the internal pressure of the negative pressure tank 19. The negative pressure tank 19 is sucked into a negative pressure state through the negative pressure pump 18. After the set negative pressure value is reached, the negative pressure pump 18 stops, and the electromagnetic valve 25 is electrically connected to the geomagnetic induction module 9. After the geomagnetic induction module 9 senses that the feeding vehicle enters the unloading room 3, the electromagnetic valve 25 is opened, so that The negative pressure tank 19 is connected to the inside of the negative pressure box 22, and the air inside the negative pressure box 22 is adsorbed by the negative pressure state inside the negative pressure tank 19. When unloading, the inside of the negative pressure box 22 is adsorbed by the negative pressure tank 19 to form a negative pressure state, and then the dust near the discharge hopper 8 is adsorbed through the dust suction pipe 10 and the dust hood 16. The dust generated during unloading is collected by the dust suction hood 16 and then adsorbed from the dust suction pipe 10 to the inside of the negative pressure box 22. The dust inside the negative pressure box 22 is sucked into the dust collection bag 31 through the dust collection pipe 10 and intercepted and collected. After the dust collection bag 31 is full of dust, the outer door 5 of the equipment room 2 and the negative pressure box 22 are opened in turn. The inner door 23 of the vacuum box 22 is opened, the clamp 33 is removed to release the connection between the dust bag 31 and the connecting pipe 32, the bag opening is tightened, and the ash storage cart 27 is pulled out through the handle 30. The dust bag 31 filled with dust can be conveniently transferred to the processing point through the ash storage cart 27. After the ash storage cart 27 is sent back to the negative pressure box 22, a new dust bag 31 can be installed again to continue the operation. The three-layer air curtain formed by the first air curtain machine 701, the second air curtain machine 702 and the third air curtain machine 703 will prevent the dust generated when the feeding cart enters the unloading room 3 to unload, thereby improving the on-site working environment.
