Description

Technical Field

[0001] The utility model relates to the technical field of cleaning screens, and particularly relates to an efficient vibration cleaning screen. Background Technique

[0002] A cleaning screen is a device used for cleaning and screening materials, generally used in fields such as grain processing and feed processing. The device utilizes a screen surface with a certain aperture size, and through mechanical vibration, the materials move on the screen surface, so that fine particles pass through the screen holes, while larger particles are retained on the screen surface, thereby achieving the purpose of separating materials with different particle sizes;

[0003] When the existing cleaning screen feeds materials into the cleaning screen through a hopper, since the materials will directly impact and accumulate on the screen of the cleaning screen, when the cleaning screen vibrates, some materials will accumulate and move, resulting in a reduction in the screening quality of the cleaning screen, and the materials need to be re-screened, thus leading to a reduction in the screening efficiency of the cleaning screen. Therefore, the Chinese utility model patent with the publication number CN208004285U: an efficient vibration cleaning screen. This application achieves the effect of driving the moving plate to move through the cooperation of a connecting rod, a slider and a chute, thereby making the feeding amount at the material inlet controllable and achieving the effect of facilitating the adjustment of the material feeding amount. Through the motor arranged at the screening material outlet, through the cooperation of the rotating rod and the stirring rod when the motor rotates, it achieves a good loosening effect on the grains at the screening material outlet, thereby effectively preventing the problem that the screening material outlet is easily blocked. When the feeding amount of the material is reduced by the moving plate, since the materials will gradually accumulate in the material inlet, it is easy for the materials to aggregate into groups and not slide smoothly, thus gradually accumulating and forming a blockage at the feeding port.

[0024] As Figures 1-6 shown, a high-efficiency vibration cleaning sieve provided by the present utility model includes a screening box 1. A discharge port 2 and a slag discharge port 3 are respectively fixedly installed at one end of the screening box 1. A vibration motor 4 is fixedly installed at the lower end of the screening box 1. The vibration motor 4 is electrically connected to an external main controller through a connecting wire. A support 5 is further arranged at the lower end of the screening box 1. The support 5 is movably connected to the screening box 1 through a plurality of support springs 6. A screen 7 is fixedly installed inside the screening box 1. A top cover 8 is movably installed on the screening box 1. A feed hopper 9 is fixedly installed on the top cover 8. A spreading mechanism 10 is arranged at the lower end of the feed hopper 9. The spreading mechanism 10 includes a guide tube 11 and a spreading tube 12. The upper end of the guide tube 11 is fixedly installed at the lower end of the feed hopper 9 and is located below the top cover 8. The upper end of the spreading tube 12 is movably installed at the lower end of the guide tube 11. An adjusting plate 13 is movably installed on one side of the spreading tube 12.

[0025] As Figures 2-5 shown, first enclosing plates 15 are fixedly installed on both sides of the guide tube 11. Displacement grooves 16 are formed inside the first enclosing plates 15. A plurality of first connecting screws 17 are inserted into the displacement grooves 16. A storage groove 18 is formed on one side of the spreading tube 12. A plurality of fixing blocks 19 are fixedly installed inside the storage groove 18. Slots 20 are formed inside the fixing blocks 19. An insertion plate 21 is inserted between the plurality of fixing blocks 19. With the arrangement of the storage groove 18 and the fixing blocks 19, basic conditions can be provided for the up and down adjustment of the adjusting plate 13;

[0026] As Figures 4-6As shown in the figure, a plurality of sliding grooves 29 are formed in the adjusting plate 13, and a plurality of tooth grooves 30 are formed in the adjusting plate 13 between the two sliding grooves 29. The adjusting plate 13 is inserted and installed on a plurality of fixing blocks 19 in the receiving groove 18 through the plurality of sliding grooves 29. By arranging the adjustable adjusting plate 13 in the receiving groove 18, the distance between the bottom of the adjusting plate 13 and the screen 7 can be adjusted, so as to adjust the discharge amount. A plurality of engaging teeth 22 are fixedly installed on one side of the inserting plate 21 relative to the adjusting plate 13, and limiting blocks 23 are fixedly installed at both ends of the inserting plate 21. A connecting seat 14 is arranged at one end of the fixing block 19, and two pull rods 24 are fixedly connected between the plurality of connecting seats 14. A second connecting screw 25 is inserted into the connecting seat 14, and one end of the second connecting screw 25 passes through a through hole on one side in the inserting slot 20 and is threadedly connected to a screw groove on one side of the inserting plate 21. A first compression spring 26 is sleeved on the second connecting screw 25 between one side in the inserting slot 20 and the inserting plate 21. Through the acting force of the first compression spring 26 on the inserting plate 21, a plurality of engaging teeth 22 on one side of the inserting plate 21 can be engaged in the corresponding tooth grooves 30, so as to provide stable limitation for the adjusting plate 13 with adjustable height.

[0027] As Figures 2-3 shown in the figure, second enclosing plates 27 are fixedly installed on both sides of the material spreading cylinder 12 located above the receiving groove 18. The second enclosing plates 27 are inserted and installed in the corresponding displacement grooves 16. One end of the first connecting screw 17 is threadedly connected to a screw groove on one side of the second enclosing plate 27. A second compression spring 28 is sleeved on the first connecting screw 17 between the second enclosing plate 27 and the inner side of the displacement groove 16. The material spreading cylinder 12 is movably installed in the displacement groove 16 through the cooperation of the second enclosing plates 27, the first connecting screw 17 and the second compression spring 28, so that the material spreading cylinder 12 vibrates at a certain frequency by means of the vibration of the screening box 1, which is convenient for the material spreading cylinder 12 to discharge materials at a uniform speed and prevents blockage.

[0028] It should be noted that for an efficient vibrating cleaning screen of the present utility model, when feeding materials onto the screen 7 through the feeding hopper 9, the guide cylinder 11 and the material spreading cylinder 12, the materials can be fed into the material spreading cylinder 12 and the guide cylinder 11 through an external material conveying mechanism. Subsequently, the vibration motor 4 is started through an external controller, so that the screening box 1 vibrates by means of the vibration motor 4, and then the screening box 1 drives the screen 7 to vibrate synchronously, so that the screen 7 gradually discharges the materials in the material spreading cylinder 12 and the guide cylinder 11 from the channel between the adjusting plate 13 and the screen 7. At the same time, the screening box 1 also drives the guide cylinder 11 and the material spreading cylinder 12 to vibrate, so that the material spreading cylinder 12 reciprocally swings in the displacement grooves 16 of the two first enclosing plates 15 by means of the two second enclosing plates 27 due to vibration, so that the materials can continuously flow out from the channel between the adjusting plate 13 and the screen 7 and be evenly spread on the screen 7. At the same time, it also prevents the materials from being blocked in the guide cylinder 11 and the material spreading cylinder 12 and improves the screening quality of the materials.

[0029] When it is necessary to adjust the channel height between the adjusting plate 13 and the screen 7 according to the screening requirements of the material, the two pull rods 24 can be manually pulled to one side. Then, the two pull rods 24 drive a plurality of connecting seats 14 to move to one side. Further, the connecting seats 14 drive the insertion plate 21 to move to one side through the second connecting screws 25. Then, the engaging teeth 22 on one side of the insertion plate 21 disengage from the corresponding tooth grooves 30 on one side of the adjusting plate 13. Further, it is convenient for the adjusting plate 13 to move up and down on the plurality of fixing blocks 19 in the receiving groove 18 through the sliding groove 29, so as to adjust the distance between the adjusting plate 13 and the screen 7. When the adjustment of the adjusting plate 13 is completed, the pull rods 24 can be released. Then, by using the rebounding force of the first compression spring 26, the insertion plate 21 moves towards the adjusting plate 13. Then, the engaging teeth 22 on one side of the adjusting plate 13 are engaged into the corresponding tooth grooves 30, so as to limit the adjusting plate 13 and prevent the adjusting plate 13 from loosening and displacing due to the vibration of the equipment.
