After the material enters from the feed port, it moves along the direction of the screw shaft under the push of the screw blades, just like a nut rotating and moving forward on a screw, thereby realizing the material conveying. Finally, the conveyed material is discharged into the processing equipment through the discharge port, thus realizing the feeding of the equipment.

[0003] In the existing technology, when using a screw feeder to feed glass sand during the processing of glass sand, if there are large particles in the glass sand, it may affect the quality of the subsequent processed products.

The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0029] Reference Figure 1-7 This utility model discloses a glass sand feeding device with screening function, which includes a screw feeder 1, a feed pipe 2, a discharge hopper 3, a discharge pipe 4, and support legs 5. A bearing plate 6 is fixedly connected to the side surface of the discharge hopper 3, a motor 7 is fixedly connected to the lower surface of the bearing plate 6, a rotating shaft 8 is fixedly connected to the output end of the motor 7, a turntable 9 is fixedly connected to the upper surface of the rotating shaft 8, two push blocks 10 are fixedly connected to the outer surface of the turntable 9, and there are multiple support legs 5. The motor 7 is electrically connected to an external power source, the outer surface of the rotating shaft 8 is rotatably connected to the bearing plate 6, the side surface of the support legs 5 is fixedly connected to the screw feeder 1, the side surface of the feed pipe 2 is fixedly connected to the screw feeder 1, the side surface of the discharge pipe 4 is fixedly connected to the screw feeder 1, and the lower surface of the discharge hopper 3 is fixedly connected to the feed pipe 2. The screw feeder 1 is a mature existing technology, so its specific structure and working principle will not be described in detail here.

[0030] Two limiting rods 11 are fixedly connected to the inner surface of the feeding hopper 3. A first guide block 12 is fixedly connected to the upper surface of each limiting rod 11. A connecting ring 13 is slidably connected to the inner surface of the feeding hopper 3. A sieve plate 14 is fixedly connected to the connecting ring 13. Two first guide grooves 15 are formed on the connecting ring 13. The outer surface of the first guide block 12 is slidably connected to the first guide groove 15. A connecting block 16 is fixedly connected to the side surface of the connecting ring 13. A connecting rod 17 is fixedly connected to the inner surface of the connecting block 16. A roller 18 is rotatably connected to the outer surface of the connecting rod 17. A second guide block 19 is fixedly connected to the lower surface of the connecting block 16. A second guide groove 20 is formed on the bearing plate 6. The outer surface of the sieve plate 14 is slidably connected to the feeding hopper 3, and the outer surface of the second guide block 19 is slidably connected to the second guide groove 20. Two guide rods 21 are fixedly connected to the side surface of the feeding hopper 3. Anti-detachment blocks 22 are fixedly connected to the side surface of each guide rod 21. Two sliders 23 are fixedly connected to the lower surface of the connecting ring 13. Springs 24 are slidably sleeved on the outer surface of each guide rod 21. The inner surface of the slider 23 is slidably connected to the guide rod 21. The guide rod 21 passes through the slider 23. One end of the spring 24 is fixedly connected to the side surface of the slider 23. The end of the spring 24 away from the slider 23 is fixedly connected to the side surface of the anti-detachment block 22. Under the action of the second guide block 19 and the second guide groove 20, the movement of the connecting block 16 and other structures can be guided and limited, improving the stability of the connecting block 16 and other structures when they move. Under the action of the spring 24, the connecting ring 13, the sieve plate 14 and other structures can automatically move to reset.

[0031] Working principle: After glass sand is added into the feeding hopper 3, it will come into contact with the sieve plate 14 inside the feeding hopper 3. The sieve plate 14 has many screen holes evenly distributed on it, so glass sand that meets the particle size requirements will continue to pass through the sieve plate 14 into the feed pipe 2, and continue to be fed by the screw feeder 1. At this time, the motor 7 on the bearing plate 6 is started, so that the started motor 7 can drive the rotating shaft 8, the turntable 9 and the push block 10 to rotate. During the rotation of the push block 10, it will gradually come into contact with the roller 18. When the push block 10 is in contact with the roller 18... During the process, the roller 18, connecting rod 17, connecting block 16, connecting ring 13, sieve plate 14, second guide block 19, and other structures on the connecting ring 13 will gradually move. When the moving connecting ring 13 drives the slider 23 to move on the guide rod 21, it will gradually compress the spring 24 on the anti-detachment block 22, thus keeping the spring 24 in a taut state. Furthermore, when the moving connecting ring 13 drives the first guide block 12 to move within the first guide groove 15 on the limiting rod 11, it can move the connecting ring 13 and the sieve plate 14. The movement of the push block 10 acts as a limit, thereby increasing the stability of the connecting ring 13, sieve plate 14, and other structures during movement. When the rotating push block 10 is no longer in contact with the roller 18, the spring 24 is no longer compressed and rebounds, allowing the rebounding spring 24 to drive the slider 23, connecting ring 13, sieve plate 14, and other structures on the connecting ring 13 to move back to their original positions. When the rotating push block 10 contacts the roller 18 again, it will continue to drive the connecting ring 13, sieve plate 14, and other structures on the connecting ring 13 to move, and the spring 24 will continue to move. When the rotating pusher 10 is not in contact with the roller 18, under the action of the spring 24, it will drive the connecting ring 13, the sieve plate 14 and other structures on the connecting ring 13 to move back to their original positions. This process is repeated to enable the sieve plate 14 to move. In the process of the sieve plate 14 moving, it will also drive the glass sand on the sieve plate 14 to move. At this time, under the action of shaking, the glass sand has more opportunities to approach and pass through the sieve holes, which can not only speed up the screening efficiency of the sieve plate 14, but also reduce the probability of clogging of the sieve holes.

[0032] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
