[0031] Working principle: When in use, people throw garbage into the garbage bag from the delivery port, and the garbage bag falls onto the opening and closing plate 3. The opening and closing plate 3 is pressed and flipped downward, so that the garbage bag falls onto the two bag-breaking rods 5 in the delivery box 1. The bag-breaking knife head 6 above the bag-breaking rod 5 is directly inserted into the garbage bag. At this time, the pull ring 12 is manually pulled to pull the pull rope 7 to move. When the pull rope 7 moves, it drives the two bag-breaking rods 5 to move away from each other. The bag-breaking knife head 6 tears the garbage bag, so that the garbage inside falls onto the baffle plate 15. At this time, people start the first motor 19 through the controller 9. The first motor 19 drives the cam 20 to rotate. When the cam 20 rotates, the baffle plate 15 moves up and down following the rotation of the cam 20. The connecting rod 16 on the baffle plate 15 The guide groove 14 slides, so that the baffle plate 15 moves up and down and rotates left and right at the same time, and the garbage above the baffle plate 15 is preliminarily separated. Thereafter, the electronic telescopic rod and the fan 21 are started synchronously, and the two flip plates 17 are flipped downward by the contraction of the electronic telescopic rod, so that the preliminarily separated garbage continues to fall. The airflow generated by the fan 21 blows the falling garbage, so that the light and easy-to-recycle garbage is blown to the inside of the collection box 2, and then gradually falls into the garbage can 27 placed below, while the heavier garbage falls directly onto the guide plate 28 and rolls into the first garbage can 27 for collection. When the garbage is sorted through the air separation, the second motor 39 is started, and the second motor 39 drives the rotating rod 41 to rotate, thereby driving The two winding drums 44 rotate to reel in the connecting rope 25, so that the connecting rope 25 pulls the baffle 24 to flip close to the upper edge of the trash can 27, and the garbage hanging on the baffle 24 automatically slides into the trash can 27. At the same time, when the rotating rod 41 rotates, it drives the worm 42 to rotate. When the worm 42 rotates, it drives the worm wheel 43 to rotate, thereby driving the transmission rod 46 to rotate. The active bevel gear 47 on the transmission rod 46 drives the driven bevel gear 48 on the screw 49 to rotate, thereby driving the screw 49 to rotate. When the screw 49 rotates, the slider 50 moves along the top of the guide plate 28, scraping the garbage remaining on the guide plate 28 into the first trash can 27. At the same time, the long brush 51 at the lower end of the slider 50 touches the upper end surface of the guide plate 28. Cleaning is carried out to remove the garbage in the guide hole on the guide plate 28. A torsion spring 26 is provided between the baffle 24 and the vertical plate 23. By controlling the second motor 39 to flip, the slider 50 and the baffle 24 are reset. When the garbage bag contains liquid, the liquid flows into the guide plate 29 through the drainage hole on the guide plate 28, and flows into the collection barrel 31 through the drainage pipe 30 for storage. The rain collecting box 32 at the upper end of the collection box 2 collects rainwater and stores it in the rainwater barrel 37 through the diversion pipe 33. When the delivery box 1 needs to be cleaned, the water pump 36 is started. The water pump 36 transports the collected rainwater through the water supply pipe 34 to the nozzle 35 for spraying, so as to clean the inside of the delivery box 1 and avoid the generation of odor in the delivery box 1.
