Description

Technical Field

[0001] This utility model relates to a planar rotary screen cleaning device with a self-cleaning brush, belonging to the field of planar rotary screen technology. Background Technology

[0002] A rotary screen is driven by an electric motor to reducer, which in turn drives the main shaft of the rotary screen to rotate through a transmission sprocket (or coupling). The screen has a mesh, and as the material passes through the screen, it rotates with the mesh to achieve the purpose of separating the material into particles of different sizes. For example, a planar rotary screen with patent number CN202021306329.8 belongs to rice processing equipment. It aims to provide a planar rotary screen that is convenient for cleaning foreign objects such as stones remaining in the screen body. It includes a frame and a screen body. The screen body is placed on the frame and has a disassembly port. The screen body has an upper screen and a lower screen. The upper screen and the screen body are detachably connected. One end of the lower screen is hinged to the screen body, and the other end of the lower screen is movably connected to the screen body. Both ends of the lower screen are in contact with the inner wall of the screen body. The frame is equipped with a blowing device, which includes a blower, a bellows, and a nozzle. The blower is placed on the frame, and the bellows is fixed in the screen body. The blower and the bellows are connected by a duct. The bellows are hollow and are placed between the upper screen and the lower screen. The nozzles are connected to the bellows. The other end of the lower screen is in contact with the bellows. Since the screen plate used in the above-mentioned flat rotary screen is a conventional screen plate, its vibration screening effect on materials is limited, and impurities and dust on the materials may adhere to the screen plate. The accumulation of impurities over a long period of time will affect the screening effect of subsequent materials, which will have a certain adverse effect on actual use. Therefore, it is necessary to improve it. Utility Model Content

[0003] The purpose of this invention is to provide a planar rotary cleaning screen device with a self-cleaning brush. This invention sets a screening and transfer frame to connect with the upper and lower planar rotary screen plates, which can filter and screen materials using the stepped screen plates and screen holes. It also adds a driven and controlled moving brush plate to comb the materials and clean impurities, thereby solving the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: A planar rotary cleaning screen device with a self-cleaning brush includes a screening transfer frame. An upper planar rotary screen plate and a lower planar rotary screen plate are fixedly connected to the left side of the screening transfer frame. A stabilizing guard is fixedly connected to the top of the upper planar rotary screen plate. A locking component is connected to the top of the stabilizing guard. An upper guard plate is connected to the surface of the locking component. An adjusting frame is fixedly connected to the bottom right side of the upper guard plate. A drive motor is fixedly installed on the inner wall of the adjusting frame. A threaded rotating rod is fixedly connected to the output end of the drive motor. A threaded sleeve plate is threadedly connected to the surface of the threaded rotating rod. A movable brush plate is fixedly installed on the side of the threaded sleeve plate by a locking block.

[0005] Furthermore, the main body of both the upper and lower rotating screen plates is a recessed frame, and a trapezoidal screen platform is fixedly connected to the left side of the recessed frame. A dredging screen hole is opened on the left side of the trapezoidal screen platform.

[0006] Furthermore, a dustproof sleeve is fixedly connected between the bottom of the upper plane rotary screen plate and the top of the lower plane rotary screen plate, and the surface of the dustproof sleeve is coated with a wear-resistant coating.

[0007] Furthermore, the locking assembly includes a locking plate and a locking slot. The locking plate is fixedly connected to the bottom of the upper guard plate, and the locking slot is opened on the top of the stabilizing guard. The inner wall of the locking slot and the surface of the locking plate engage and fit together.

[0008] Furthermore, the limiting component includes a limiting slide plate and a limiting groove. The limiting slide plate is fixedly connected to the surface of the threaded sleeve plate, and the limiting groove is formed on the inner wall of the adjusting frame. The inner wall of the limiting groove and the surface of the limiting slide plate are slidably connected.

[0009] Furthermore, a balance slide plate is fixedly connected to the bottom of the upper guard plate near its left side, and a balance slide plate is fixedly connected to the left side of the movable brush plate. The surface of the balance slide plate and the inner wall of the balance slide plate are slidably connected.

[0010] Furthermore, a stress-relieving telescopic rod with a shock-absorbing spring is fixedly installed on the right side of the inner wall of the screening transfer frame, and one end of the stress-relieving telescopic rod is fixedly connected to a crash protection plate with a rubber pad.

[0011] The beneficial effects of this utility model are: 1. In this utility model, the screening transfer frame is set as a sealed transfer frame on the right side, which facilitates the transfer of vibrating screening materials by the upper and lower rotating screen plates. Both the upper and lower rotating screen plates can discharge material impurities through their unblocking screen holes. The stepped screen platform can achieve the effect of vibration, turbulence, screening, and discharge of materials. The discharged materials will impact the sealed transfer frame for vertical diversion and guidance. The shock absorption is controlled by the force-relieving telescopic rod in the screening transfer frame. The impact is mitigated by the anti-collision guard plate. A dustproof sleeve is set between the upper and lower rotating screen plates to protect the materials during the screening process and cover dust, thus achieving the screening, protection, and transfer effect of the materials. 2. In this utility model, the brush surface of the movable brush plate on the upper guard plate faces downward, allowing it to contact the upper part of the upper rotary screen plate. The drive motor rotates the threaded rod, and the movement trajectory of the threaded sleeve is limited by the limiting slide plate and limiting groove. This allows the rotation of the threaded rod to move the threaded sleeve, which in turn moves the movable brush plate in the forward and backward direction. Guided by the balancing slide plate and balancing slide plate on the left side, the movable brush plate, moving in the forward and backward direction, can repeatedly comb the upper rotary screen plate, completing the combing operation on the top of the upper rotary screen plate and clearing blockage-preventing materials. This achieves a multi-screening self-cleaning effect during the rotary screen material screening process. Attached Figure Description

[0014] 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.

[0015] Please refer to Example 1 Figures 1-7 This utility model provides a technical solution: A planar rotary cleaning screen device with a self-cleaning brush includes a screening transfer frame 1. An upper planar rotary screen plate 2 and a lower planar rotary screen plate 3 are fixedly connected to the left side of the screening transfer frame 1. A stabilizing guard 4 is fixedly connected to the top of the upper planar rotary screen plate 2. A locking component is connected to the top of the stabilizing guard 4. An upper guard plate 5 is connected to the surface of the locking component. An adjusting frame 6 is fixedly connected to the bottom of the upper guard plate 5 near its right side. A drive motor 7 is fixedly installed on the inner wall of the adjusting frame 6. A threaded rotating rod 8 is fixedly connected to the output end of the drive motor 7. A threaded sleeve plate 9 is threadedly connected to the surface of the threaded rotating rod 8. A movable brush plate 10 is fixedly installed on the side of the threaded sleeve plate 9 by a locking block.

[0016] Specifically, such as Figures 1-7 As shown, the main body of the upper plane rotary screen plate 2 and the lower plane rotary screen plate 3 is a concave frame. A trapezoidal screen platform 11 is fixedly connected to the left side of the concave frame. A clearing screen hole 12 is opened on the left side of the trapezoidal screen platform 11. Both the upper plane rotary screen plate 2 and the lower plane rotary screen plate 3 can discharge material impurities through the clearing screen hole 12. The material can be vibrated and sieved through the stepped screen platform 11 to achieve the effect of material vibration and sieving.

[0017] Furthermore, a dustproof sleeve 13 is fixedly connected between the bottom of the upper plane rotary screen plate 2 and the top of the lower plane rotary screen plate 3, and the surface of the dustproof sleeve 13 is coated with a wear-resistant coating. The dustproof sleeve 13 between the upper plane rotary screen plate 2 and the lower plane rotary screen plate 3 can protect the material during the screening process and cover the dust.

[0018] Specifically, such as Figures 1-7 As shown, the locking assembly includes a locking plate 14 and a locking slot 15. The locking plate 14 is fixedly connected to the bottom of the upper guard plate 5, and the locking slot 15 is opened on the top of the stabilizing guard 4. The inner wall of the locking slot 15 and the surface of the locking plate 14 are engaged and adapted. The locking plate 14 and the locking slot 15 can be used for connecting and disassembling the upper guard plate 5 on the stabilizing guard 4.

[0019] Furthermore, the limiting component includes a limiting slide plate 16 and a limiting groove 17. The limiting slide plate 16 is fixedly connected to the surface of the threaded sleeve plate 9, and the limiting groove 17 is formed on the inner wall of the adjusting frame 6. The inner wall of the limiting groove 17 and the surface of the limiting slide plate 16 are slidably connected. By setting the limiting slide plate 16 and the limiting groove 17, the movement trajectory of the threaded sleeve plate 9 is limited, so that the rotation of the threaded rod 8 can drive the threaded sleeve plate 9 to move.

[0020] Furthermore, a balance sliding plate 18 is fixedly connected to the bottom of the upper guard plate 5 near its left side, and a balance sliding plate 19 is fixedly connected to the left side of the movable brush plate 10. The surface of the balance sliding plate 19 is slidably connected to the inner wall of the balance sliding plate 18. Under the guidance of the balance sliding plate 18 and the balance sliding plate 19 on the left side, the movable brush plate 10, which moves in the front and back direction, can repeatedly comb the upper plane rotary screen plate 2.

[0021] Please refer to Example 2 Figures 1-7 The difference between this embodiment and embodiment 1 is that: a stress-relieving telescopic rod 20 with a shock-absorbing spring is fixedly installed on the right side of the inner wall of the screening transfer frame 1. One end of the stress-relieving telescopic rod 20 is fixedly connected to an anti-collision guard plate 21 with a rubber pad. The stress-relieving telescopic rod 20 in the screening transfer frame 1 is controlled to resist vibration, and the anti-collision guard plate 21 is used to mitigate the impact force of the material.

[0022] The working principle of this utility model is as follows: During use, the screening transfer frame 1, acting as a sealed transfer frame on the right side, facilitates the transfer of vibrating screening materials between the upper and lower rotating screen plates 2 and 3. Both the upper and lower rotating screen plates 2 and 3 allow material impurities to be discharged through their unblocking screen holes 12. The stepped screen platform 11 provides a vibrating and turbulent screening effect, directing the material's flow. The discharged material impacts the sealed transfer frame for upward and downward flow guidance. The shock absorption is controlled by the force-relieving telescopic rod 20 within the screening transfer frame 1, and the impact is mitigated by the anti-collision guard plate 21. A dustproof sleeve 13 is installed between the upper and lower rotating screen plates 2 and 3 to protect the material during screening and cover it from dust. A locking plate 14 and a locking groove 1 are also included. 5 can be used to connect the upper guard plate 5 on the stabilizing guard 4, and to perform subsequent disassembly and assembly of the upper guard plate 5 to complete the cleaning operation of its upper structure. Under normal conditions, the brush surface of the movable brush plate 10 on the upper guard plate 5 faces downwards, and the drive motor 7 can drive the threaded rotating rod 8 to rotate. Through the setting of the limiting slide plate 16 and the limiting slide groove 17, the movement trajectory of the threaded sleeve plate 9 is limited, so that the rotation of the threaded rotating rod 8 can drive the threaded sleeve plate 9 to move, which can drive the movable brush plate 10 to move in the front and back direction. Under the guidance of the balance slide plate 18 and the balance slide plate 19 on the left side, the movable brush plate 10, which moves in the front and back direction, can repeatedly comb the upper plane rotary screen plate 2, and can complete the combing operation on the top of the upper plane rotary screen plate 2, and can perform the anti-clogging material drainage activity, realizing the multi-screening self-cleaning effect in the process of screening materials by the plane rotary screen.
