[0040] The specific usage method of the present invention: Place the device in a designated area. According to the number of work positions of the garbage sorting robot, use the extension structure 2 to drive the second moving frame 15 to move and adjust the length of the device. Install the garbage sorting robot on both sides of the fixed frame 3. According to the height of the subsequent processing equipment, use the lifting structure 8 to drive the first moving frame 13 to move upward and adjust the output height of the device to dock the discharge hopper 14 with the subsequent processing equipment. Use a lifting equipment such as a forklift to pour the garbage to be processed into the hopper 7. Use the blanking structure 6 to adjust the falling speed of the garbage inside the hopper 7 to make it evenly distributed on the surface of the garbage conveyor belt 4. Start the reduction motor 19 to drive the driving roller 18 to rotate, so that the driving roller 18 drives the conveyor belt 4 to move. The conveyor belt 4 conveys the garbage falling from the hopper 7. The direction and path of the conveyor belt 4 are guided by the first deflector roller 11, the second deflector roller 17, and the magnetic separation roller 16, so that the conveyor belt 4 conveys the garbage into the discharge hopper 14. The garbage sorting robots on both sides of the fixed frame 3 conduct preliminary sorting on the conveyed garbage. At the same time, the baffle plate 10 prevents the garbage from falling into the gap between the conveyor belt 4 and the fixed frame 3 during the sorting process. The magnetic separation roller 16 uses magnetic force to adsorb ferromagnetic metal garbage, so that the ferromagnetic metal garbage cannot fall into the discharge hopper 14. When the ferromagnetic metal garbage moves to the non-magnetic area inside the metal waste tank 12, the ferromagnetic metal garbage falls into the metal waste tank 12 due to the loss of magnetic attraction. Hydraulic oil is injected into the interiors of the liquid storage cylinder 201, the first compensation cylinder 210, and the second compensation cylinder 213 by opening the liquid injection valve 208. When adjusting the working position of the garbage sorting robot, the hydraulic cylinder 209 is started to extend, pushing the second moving frame 15 to slide outward from the fixed frame 3, and the second moving frame 15 drives the first moving chassis 5 to move on the ground, accordingly adjusting the positions of the hopper 7 and the driving roller 18. At the same time, the driving roller 18 pulls the conveyor belt 4 to move, adjusting the effective length of the conveyor belt 4, thereby adjusting the number of work positions to facilitate adapting to working spaces and sorting requirements of different scales. Meanwhile, during the movement of the second moving frame 15, the second moving frame 15 pushes the first piston 212 to move inside the first compensation cylinder 210 through the first transmission rod 211, and the first piston 212 extracts the hydraulic oil inside the liquid storage cylinder 201 through the connecting pipe 202. Since the hydraulic oil inside the liquid storage cylinder 201 decreases, the third piston 217 is forced to move backward. At the same time, the tensioning rod 216 pulls the tensioning roller 219 to move backward through the first moving seat 204, compensating for the effective length of the conveyor belt 4 extended due to the movement of the driving roller 18. The tensioning roller 219 is pushed to move by the contracted tensioning spring 224, so that the tensioning roller 219 squeezes the conveyor belt 4 to ensure that it always remains in a taut state during the adjustment of the effective length of the conveyor belt 4. The movement of the first moving seat 204 is guided by the guide rail 203, enabling the first moving seat 204 to move only in a straight line. The guide rail 203 slides inside the push plate 218 to prevent the tensioning spring 224 from driving the roller frame 222 to swing; When adjusting the height of the output end of the device, the driving motor 805 is started to rotate, causing the driving motor 805 to drive the transmission bevel gear 808 to rotate. Immediately afterwards, one side of the transmission bevel gear 808 drives the first bevel gear 806 to rotate through the driven bevel gear 807 and the second bevel gear 809, causing the first bevel gear 806 to drive the lead screw 811 to rotate. Through the engagement of the threads, during the rotation of the lead screw 811, the second moving seat 810 moves up and down along the threads on the outside of the lead screw 811, and the second moving seat 810 drives the first moving frame 13 to move, causing the first moving frame 13 to slide obliquely upward along the second guide groove 206, adjusting the height of the first moving frame 13. The first moving frame 13 pulls the second piston 214 to move through the second transmission rod 215, extracting the hydraulic oil inside the liquid storage cylinder 201 into the second compensation cylinder 213, thereby causing the tensioning roller 219 to move and compensating for the effective length of the conveyor belt 4, so as to pull the conveyor belt 4 to unfold during the lifting of the first moving frame 13. Through the second moving chassis 803, it is convenient for the bottom plate 802 to move on the ground along with the first moving frame 13 during the oblique upward movement of the first moving frame 13; The driving roller 18 drives the first driving wheel 601 to rotate, causing the first driving wheel 601 to drive the deformation wheel 609 and the transmission shaft 610 to rotate through the first transmission belt 602. The transmission shaft 610 drives the material deflecting plate 616 to rotate, causing the material deflecting plate 616 to deflect the garbage falling inside the hopper 7, ensuring that the garbage falls at a uniform speed, so as to facilitate the sorting of the garbage. At the same time, during the rotation of the material deflecting plate 616, the moving tool holder 617 and the fixed tool holder 615 are staggered, enabling the fixed tool holder 615 and the moving tool holder 617 to cut the garbage, preventing the bagged garbage from jamming the material deflecting plate 616. By rotating the small gear 603, the small gear 603 drives the main gear 607 to rotate through the teeth, and during the rotation of the main gear 607, the guide rod 606 is pushed to move, causing the moving piece 604 to extend outward inside the guide seat 605 and drive the deformation wheel 609 to move, adjusting the diameter of the deformation wheel 609, thereby adjusting the rotation speed of the transmission shaft 610, so as to control the falling speed of the garbage according to the type of garbage. The compression spring 613 pushes the push frame 614 to slide in the first guide groove 205, causing the tension wheel 618 to squeeze the first transmission belt 602, ensuring the effective transmission of the first transmission belt 602. The hydraulic telescopic cylinder 611 extends to push the second moving plate 612 to move and squeeze the compression spring 613, adjusting the elasticity of the compression spring 613; The magnetic separation roller 16 drives the driven wheel 907 to rotate through the second driving wheel 905 and the second transmission belt 906, causing the driven wheel 907 to drive the brush roller 904 to roll. The brush on the surface of the brush roller 904 cleans the foreign matters attached to the surface of the conveyor belt 4. The cleaning liquid is regularly injected into the high-pressure nozzle 908, so that the high-pressure nozzle 908 can regularly perform high-pressure flushing on the conveyor belt 4. The water tank 901 receives the cleaned foreign matters and the cleaning liquid, so that the brush roller 904 can dip the cleaning liquid for cleaning, improving the cleaning effect of the brush roller 904. The stretched tension spring 902 pulls the scraper 903 to flip backward, causing the scraper 903 to scrape the cleaning liquid attached to the surface of the conveyor belt 4.
