[0011] Compared with the prior art, the present invention has the following beneficial effects:
[0012] 1. This raw material screening device for concrete production sends a signal through a controller, causing the vibrating motor to operate. The vibrating motor drives a push plate to apply pressure to a filter plate, causing the filter plate to vibrate. This vibration of the filter plate applies pressure to a connecting plate, causing the connecting plate to move along the inner wall of the sliding groove. This movement of the connecting plate also applies pressure to a spring, which in turn moves a fixed block and a rotating rod. The rotating rod's movement further drives... The connecting rod rotates on the inner wall of the fixed block, causing the cylinder to rotate on the inner wall of the rotating column. The rotating column applies pressure to the rotating column, causing it to rotate on the inner wall of the placement block. Simultaneously, the rotation of the rotating column and the connecting rod applies pressure to springs one and three, releasing the elastic potential energy of springs one, two, and three. Springs one, two, and three then drive the connecting plate and filter plate to shake rapidly on the inner wall of the screening device body, thereby achieving a good screening effect.
[0013] 2. This raw material screening device for concrete production, when collecting the screened material, sends a signal through the controller, causing the power output shaft of motor two to rotate upon receiving the signal. Motor two drives the gear to rotate, and the gear meshes with the rack, causing the rack and limit rod to move within the limit groove. As the rack moves, it drives the fixed plate and scraper to apply pressure to the screened material that is too large. Simultaneously, the motor receives a signal from the controller, causing the controller's power output shaft to drive the rotating plate to rotate, opening the discharge port trough for easy collection. During operation, the filter plate applies pressure to the scraper, causing the scraper to move within the moving trough under pressure. The scraper's movement applies pressure to spring four, preventing damage to the scraper caused by vibration of the filter plate. Attached Figure Description

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.
[0026] Please see Figure 1 - Figure 9 A raw material screening device for concrete production includes a screening device body 1, a protective shell 3 fixedly mounted on the outer wall of the screening device body 1, a pushing component 6 provided on the outer wall of the screening device body 1, a filter plate 7 slidably connected to the inner wall of the screening device body 1, a protective block 8 and a vibration motor 9 fixedly mounted on the inner wall of the screening device body 1, a fixed shell 10 fixedly mounted on the inner wall of the screening device body 1, a pushing plate 11 fixedly mounted on the power output shaft of the vibration motor 9, a sliding groove 13 formed on the inner wall of the fixed shell 10, and a spring fixedly mounted on the inner wall of the sliding groove 13. A connecting plate 12 is fixedly mounted on one end of spring 14 and the other end of spring 14. A fixing block 15 is fixedly mounted on the inner wall of the connecting plate 12. A rotating rod 16 is rotatably connected to the inner wall of the fixing block 15. A connecting rod 17 is fixedly mounted on the outer wall of the rotating rod 16. A placement block 18 is fixedly mounted on the inner wall of the fixing shell 10. One end of a rotating column 19 is rotatably connected to the inner wall of the placement block 18. A cylinder 22 is rotatably connected to the inner wall of the other end of the rotating column 19. A second spring 20 is fixedly mounted on the inner wall of the fixing shell 10. A third spring 21 is fixedly mounted on the outer wall of the rotating column 19.
[0027] In the above structure, the controller 2 sends a signal, causing the vibration motor 9 to receive the signal and drive the vibrating rod to perform the operation. The vibrating rod, driven by the vibration motor 9, acts on the push plate 11, thereby applying pressure to the filter plate 7. This causes the push plate 11 to cause the filter plate 7 to shake. During the shaking process, the filter plate 7 applies pressure to the connecting plate 12, causing the connecting plate 12 to move on the inner wall of the sliding groove 13. During the movement, the connecting plate 12 applies pressure to the spring 14, and simultaneously drives the fixed block 15 and the rotating rod 16 to move. When the rotating rod 16 moves, it drives the connecting rod 17 to rotate on the inner wall of the fixed block 15. The rotation of the connecting rod 17 causes the cylinder 22 to rotate within the inner wall of the rotating column 19. The cylinder 22 exerts pressure on the rotating column 19 during rotation, causing the rotating column 19 to rotate within the inner wall of the placement block 18. Simultaneously, the rotating column 19 and the connecting rod 17 exert pressure on the second spring 20 and the third spring 21 during rotation, causing the elastic potential energy of the first spring 14, the second spring 20, and the third spring 21 to be released at the same time. Finally, the first spring 14, the second spring 20, and the third spring 21 drive the connecting plate 12 and the filter plate 7 to shake rapidly within the inner wall of the screening device body 1, thereby achieving the purpose of efficient screening.
[0028] In a preferred embodiment: a feed pipe 4 is fixedly mounted on the top of the screening device body 1, a discharge pipe 5 is fixedly mounted on the bottom of the screening device body 1, a discharge port 23 is fixedly mounted on the outer wall of the screening device body 1, a motor 24 is fixedly mounted on the outer wall of the discharge port 23, a rotating plate 25 is fixedly mounted on the power output shaft of the motor 24, and a controller 2 is fixedly mounted on the outer wall of the screening device body 1.
[0029] In the above structure, excessively large materials are discharged through the discharge port 23, the rotating plate 25 is switched on and off by the motor 24, the raw materials for concrete are fed through the feed pipe 4, and the screened materials are discharged through the discharge pipe 5.
[0030] In a preferred embodiment: the pushing component 6 includes a support plate 601, a motor 602 is fixedly mounted on the outer wall of the support plate 601, a gear 603 is fixedly mounted on the power output shaft of the motor 602, a limiting groove 610 is formed on the top of the support plate 601, a limiting rod 609 is slidably connected to the inner wall of the limiting groove 610, a rack 604 is fixedly mounted on the top of the limiting rod 609, a fixing plate 605 is fixedly mounted on the outer wall of the rack 604, a moving groove 606 is formed on the bottom of the fixing plate 605, one end of a spring 607 is fixedly mounted on the inner wall of the moving groove 606, and a scraper 608 is fixedly mounted on the other end of the spring 607.
[0031] In the above structure, during the collection of screened materials, controller 2 sends a signal to cause motor 602 to rotate its power output shaft after receiving the signal. Subsequently, motor 602 drives gear 603 to rotate, and gear 603 meshes with rack 604. During the rotation of gear 603, rack 604 and limit rod 609 move along the inner wall of limit groove 610. During this process, the movement of rack 604 applies pressure to fixed plate 605 and scraper 608 to compress materials that are too large after screening. At the same time, motor 24 receives the signal from controller 2 and drives its power output shaft to rotate, which in turn drives rotating plate 25 to rotate, thereby opening the groove of discharge port 23 to facilitate material collection. In addition, during equipment operation, pressure is applied to scraper 608 by filter plate 7 to ensure that scraper 608 can apply pressure to spring 607 when moving along the inner wall of moving groove 606, thereby preventing filter plate 7 from damaging scraper 608 during vibration.
[0032] In a preferred embodiment: the support plate 601 is fixedly assembled with the outer wall of the screening device body 1, the rack 604 and the limiting rod 609 are both slidably connected with the inner wall of the screening device body 1, and the gear 603 meshes with the rack 604 for transmission.
[0033] In the above structure, the pushing component 6 is limited by the screening device body 1, making the pushing component 6 more stable when placed or operated. The gear 603 drives the rack 604 to move when it rotates.
[0034] In a preferred embodiment: the connecting rod 17 is fixedly assembled with the outer wall of the cylinder 22, the spring 3 21 is fixedly assembled with the connecting rod 17, the connecting plate 12 is fixedly assembled with the filter plate 7, and the push plate 11 is fixedly assembled with the filter plate 7.
[0035] In the above structure, the connecting rod 17 is limited by the cylinder 22 and the rotating rod 16, making the connecting rod 17 more stable when placed. The spring 21 is limited by the rotating column 19 and the connecting rod 17, making the spring 21 more stable when placed. The filter plate 7 is limited by the connecting plate 12 and the pushing plate 11.
[0036] In a preferred embodiment: the second spring 20 is fixedly assembled with the outer wall of the rotating column 19, the connecting plate 12 is slidably connected with the inner wall of the sliding groove 13, the vibration motor 9 is placed on the inner wall of the protective block 8, and the pushing component 6 is located on the inner wall of the protective shell 3.
[0037] In the above structure, the fixed shell 10 and the rotating column 19 limit the spring 20 so that the spring 20 will not fall when releasing its elastic potential energy. The sliding groove 13 limits the connecting plate 12 so that the connecting plate 12 can only move within the inner wall of the sliding groove 13. The protective block 8 protects the vibration motor 9, and the protective shell 3 protects the pushing component 6.
[0038] Working principle: The controller 2 sends a signal to activate the vibration motor 9. Upon receiving the signal, the vibrating rod begins operation. The vibration motor 9 drives the push plate 11 to apply pressure to the filter plate 7, causing the push plate 11 to move the filter plate 7. During this movement, the filter plate 7 applies pressure to the connecting plate 12, causing it to move along the inner wall of the sliding groove 13. This movement not only applies pressure to the spring 14 but also moves the fixed block 15 and the rotating rod 16 together. The movement of rod 16 drives connecting rod 17 to rotate on the inner wall of fixed block 15, which in turn causes connecting rod 17 to drive cylinder 22 to rotate on the inner wall of rotating column 19. The rotation of cylinder 22 applies pressure to rotating column 19, causing it to rotate on the inner wall of placement block 18. At the same time, the rotation of rotating column 19 and connecting rod 17 applies pressure to spring 20 and spring 3, causing the elastic potential energy of spring 14, spring 20, and spring 3 to be released simultaneously. The release of this energy is achieved through spring 14, spring 20, and spring 3. 0 and spring 21 drive the connecting plate 12 and filter plate 7 to shake rapidly on the inner wall of the screening device body 1, thereby achieving efficient screening. When collecting the screened material, the controller 2 sends a signal again to drive the power output shaft of motor 602 to rotate. The rotation of motor 602 drives gear 603 to rotate and meshes with rack 604, so that when gear 603 rotates, it drives rack 604 and limit rod 609 to move on the inner wall of limit groove 610. During the movement, rack 604 pushes fixed plate 60 5 and scraper 608 apply pressure to the material that is too large to be screened. At the same time, motor 24 receives a signal from controller 2 and drives the power output shaft of controller 2 to rotate rotating plate 25, opening the slot of discharge port 23 to facilitate material collection. During equipment operation, filter plate 7 applies pressure to scraper 608 to ensure that scraper 608 moves on the inner wall of moving trough 606 after being subjected to pressure, and applies pressure to spring 607 through the movement of scraper 608 to avoid damage to scraper 608 when filter plate 7 vibrates.
[0039] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
