By starting the double-headed motor 2 to drive the auxiliary blocks 3, 5, 6, and 8 on both sides of the double-headed motor 2 to rotate, the conveying screw rod 18 is driven to work. When it is necessary to adjust the direction of the discharge port, start the motor 9, so that the output end of the motor 9 drives the incomplete gear 10 and the incomplete gear 11 to mesh and rotate, thereby driving the fixing plate 13 and the conveying bin 14 to rotate, thus adjusting the direction of the discharge port. When it is necessary to change the material conveying direction, the operator can quickly and simply adjust the direction of the discharge port without replacing the equipment or performing complex adjustment work, thereby saving time and labor costs.

[0032] One end of the incomplete gear II 11 is fixedly connected to a fixing plate 13. One end of the fixing plate 13 is fixedly connected to a conveying bin 14. A lid 15 is rotatably connected to the conveying bin 14. A conveyor feed inlet 16 is provided on the conveying bin 14. A conveyor discharge outlet 17 is provided below the conveying bin 14. A conveying screw rod 18 is rotatably connected inside the conveying bin 14. A fixing sleeve II 21 is fixedly connected to the conveying bin 14. A fixing sleeve I 20 is fixedly connected to the lid 15. A bolt 19 is threadedly connected inside the fixing sleeve I 20. A motor II 22 is fixedly connected below the support platform 1. The output end of the motor II 22 is fixedly connected to a worm 23. One end of the worm 23 is meshed and connected to a worm gear 24. A threaded rod 25 is threadedly connected to the worm gear 24. A sliding column 26 is fixedly connected below the support platform 1. A base 27 is provided below the support platform 1. Universal wheels 28 are provided below the base 27. One end of the connecting rod 12 is rotatably connected below the incomplete gear I 10. The bottom end of the incomplete gear II 11 slides above the support platform 1. One end of the conveying screw rod 18 is fixedly connected to one side of the auxiliary block IV 8. One end of the bolt 19 is threadedly connected inside the fixing sleeve II 21. The bolt 19 passes through the motor II 22 and the fixing sleeve II 21. The worm gear 24 is rotatably connected above the base 27. One end of the threaded rod 25 is rotatably connected below the support platform 1 and the other end is rotatably connected to the base 27. The worm 23 is rotatably connected above the base 27. The sliding column 26 is slidably connected inside the base 27. There are two groups of conveying screw rods 18 which are respectively located at both ends of the double-headed motor 2. The two groups of conveying screw rods 18 are arranged in a mirror image of each other. By turning on the motor II, the output end of the motor II drives the two groups of worms and worm gears to mesh and rotate. When the worm gear rotates, it drives the threaded rod to rotate, thereby driving the two groups of threaded rods to lift while driving the support platform to lift, so as to adjust the height of the conveyor discharge outlet, enabling the screw conveyor to flexibly adjust its working height according to different working conditions and material characteristics, and thus better meeting various requirements in the medical hazardous waste treatment process.

[0033] Working principle: When using the bidirectional spiral conveyor, first turn on the second motor 22, so that the output end of the second motor 22 drives the worm 23 and the worm gear 24 to engage and rotate. While rotating, it drives the threaded rod 25 to move up and down, so that one end of the two threaded rods 25 rotates below the support table 1 and the other end rotates above the base 27. The four sliding columns 26 slide above the base 27, and the support table 1 is adjusted to a suitable height during work. Then turn on the first motor 9, so that the output end of the first motor 9 drives the first incomplete gear 10 and the second incomplete gear 11 to engage and rotate, thereby driving the second incomplete gear 11 to slide above the support table 1. While the second incomplete gear 11 rotates, it drives the fixing plate 13 fixedly connected to one side of the second incomplete gear 11 to rotate, thereby driving the conveying bin 14 to rotate, so that the discharge port 17 of the conveyor is aligned with the feed port of the rotary kiln. Then turn on the double-headed motor 2, so that the output end of the double-headed motor 2 drives the auxiliary block 3 on both sides to rotate. While the auxiliary block 3 rotates, it drives the rotating block 4 to rotate, thereby driving the auxiliary block 5, the auxiliary block 6, the rotating block 7, and the auxiliary block 8 to rotate. While the auxiliary block 8 rotates, it drives the conveying screw rod 18 to rotate in the conveying bin 14. Then pour the medical hazardous waste into the feed port 16 of the conveyor. Then, under the action of the conveying screw rod 18, it is conveyed to the discharge port 17 of the conveyor and then falls into the rotary kiln. When encountering a material jamming situation, turn the bolt 19 so that the bolt 19 moves away from the first fixing sleeve 20 and the second fixing sleeve 21. Then turn the lid 15 so that the lid 15 is in an open state, and the material jamming situation in the conveying screw rod 18 can be checked and cleaned in time.

[0034] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention.
