[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0021] Please see Figures 1-5A vibrating screening device for waste sorting includes a frame 13. Two sets of grooves are evenly distributed on the bottom of the inner wall of the frame 13. A discharge port is formed through the bottom of each groove. A screen plate 14 is placed within the groove. Two sets of insertion holes are evenly distributed on the front and rear sides of the screen plate 14. Two sets of through holes are evenly distributed on the front and rear sides of the inner wall of each groove. Two sets of support frames 17 are evenly fixedly mounted on the top of the frame 13. A sliding groove is formed at the bottom of each support frame 17. A bidirectional lead screw 25 is rotatably mounted within the sliding groove. Two sets of internally threaded sliders 16 are evenly screwed onto the outer wall of the bidirectional lead screw 25. A connecting plate 15 is fixedly mounted at the bottom of each internally threaded slider 16. Two sets of first pins 19 are evenly fixedly mounted on opposite sides of the two sets of connecting plates 15, with the first pins 19 penetrating through the through holes. The first pin 19 is inserted into the insertion hole of the frame 13 and then into the insertion hole of the screen plate 14, thereby fixing the screen plate 14 in the groove of the frame 13. The front side of the double-acting screw 25 passes through the front side of the support frame 17 and is connected to the handwheel 18. The left side of the support frame 17 is fixedly provided with the first support sleeve 2. The left side of the handwheel 18 is provided with a locking hole. The second pin 21 is inserted into the inside of the first support sleeve 2 and is inserted into the locking hole. The left side of the second pin 21 is fixedly provided with the connecting plate 23 and the left side of the connecting plate 23 is fixedly provided with the handle 24. The connecting plate 23 is located on the left side of the first support sleeve 2. The outer ring of the second pin 21 is provided with a spring 22, which is fixedly provided between the connecting plate 23 and the first support sleeve 2. Spring 22 drives connecting plate 23 to insert second pin 21 into locking hole of handwheel 18, thereby fixing handwheel 18 and preventing the first pin 19 from loosening due to the locking force on screen plate 14 caused by rotation of handwheel 18, thus improving the reliability of the device. The top of screen plate 14 is flush with the bottom of inner side wall of frame 13. Frame 13 is located between two sets of connecting plates 15. Base 1 is placed below frame 13. Spring telescopic rods 12 are evenly fixed on the top of base 1. The telescopic ends of spring telescopic rods 12 are fixed at the bottom of frame 13. Two sets of inclined discharge troughs 11 are evenly opened on the top of base 1. Inclined discharge troughs 11 penetrate the front side of base 1 and are located below discharge port of frame 13. A motor 3 is fixedly installed at the top of the frame 13. A rotating shaft 31 is fixedly installed on the front side of the output end of the motor 3. Two sets of cams 33 are evenly fixed on the outer ring of the rotating shaft 31. The motor 3 drives the rotating shaft 31 to rotate, and the rotating shaft 31 drives the cams 33 to rotate. When the cams 33 contact the bottom of the frame 13, they push the frame 13 to move upward. When the cams 33 separate from the frame 13, the spring telescopic rod 12 will use its own rebound force to pull the frame 13 downward. This reciprocating motion causes the frame 13 to vibrate up and down, and works with the screen plate 14 to vibrate and screen the waste. The screened waste falls into the inclined discharge chute 11 through the discharge port of the frame 13 and slides out along the inclined discharge chute 11. A second support sleeve 32 is rotatably sleeved on the outer ring of the rotating shaft 31.The rotating shaft 31 is supported by a second support sleeve 32, which is fixedly mounted on the top of the base 1. The cam 33 is located below the frame 13 and corresponds to the bottom of the frame 13.
[0022] Working principle: The first pin 19 passes through the through hole of the frame 13 and is inserted into the insertion hole of the screen plate 14, thereby fixing the screen plate 14 in the groove of the frame 13. The spring 22 drives the connecting plate 23 to insert the second pin 21 into the locking hole of the handwheel 18, thereby fixing the handwheel 18. This prevents the first pin 19 from loosening due to the locking force on the screen plate 14 caused by the rotation of the handwheel 18, thus improving the reliability of the device. Furthermore, since the frame 13 vibrates vertically while the spring 22 is installed horizontally, the vibration of the frame 13 cannot drive the spring 22 to... The second pin 21 moves out of the locking hole of the handwheel 18, and the motor 3 drives the rotating shaft 31 to rotate. The rotating shaft 31 drives the cam 33 to rotate. When the cam 33 contacts the bottom of the frame 13, it will push the frame 13 to move upward. When the cam 33 separates from the frame 13, the spring telescopic rod 12 will use its own rebound force to pull the frame 13 to move downward. This reciprocates to make the frame 13 vibrate up and down, and cooperates with the screen plate 14 to vibrate and screen the garbage. The screened garbage will fall into the inclined discharge chute 11 through the discharge port of the frame 13 and slide out along the inclined discharge chute 11.
[0023] When the screen plate 14 needs to be replaced, simply pull the handle 24 to the left to drive the second pin 21 to separate from the handwheel 18 via the connecting plate 23. Then, by rotating the handwheel 18, the double-acting screw 25 is rotated. The double-acting screw 25 drives the two sets of internal thread sliders 16 to move outward synchronously. In this way, the internal thread sliders 16 drive the first pin 19 to separate from the screen plate 14. Then, the worker can push the screen plate 14 upward through the discharge port of the frame 13 to move it upward and separate it from the frame 13 for disassembly.
