Description

Technical Field

[0001] This utility model relates to a multi-layer vibrating cleaning screen with adjustable amplitude and tilt angle, belonging to the technical field of vibrating cleaning screens. Background Technology

[0002] High-efficiency vibrating cleaning screens are used to screen grains based on the different particle sizes of grains and impurities. The screen surface with screen holes of a certain size and a linear reciprocating motion is used to screen grains. It mainly removes large, small and light impurities from grains. Before screening grains, existing high-efficiency vibrating cleaning screens have difficulty separating the stones mixed in with the grains. The friction of the stones can easily damage the device. For example, a high-efficiency vibrating cleaning screen for grain with patent number CN202320034519.6 includes a screening box, a discharge port is opened on one side of the screening box, a vibrating motor is fixedly installed on one side of the screening box near the lower surface, and fixing blocks are fixedly installed on the front and rear surfaces of the screening box near both sides, and springs are fixedly connected to the lower surface of each fixing block. The aforementioned vibrating cleaning screen utilizes a relatively fixed internal structure to vibrate and screen materials for filtration. However, because the cleaning screen is a fixed structure, it is inconvenient to adjust the amplitude and material leakage, making it difficult to control the screened material and easily causing chaos or even blockage. This has certain adverse effects on actual use, and therefore, improvements are needed. Utility Model Content

[0003] The purpose of this invention is to provide a multi-layer vibrating cleaning screen with adjustable amplitude and tilt angle. This invention, by setting an amplitude adjustment frame, can adjust the structural components at the tilt angle plate, thereby controlling the vibration distance, amplitude, and angle, and achieving the effect of inclined obstruction discharge of the screened material. This ensures the internal screening material adjustment and screening effect of the vibrating cleaning screen, thus solving the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: A multi-layer vibrating cleaning screen with adjustable amplitude and tilt angle includes a cleaning screen frame. An amplitude adjustment frame is fixedly installed inside the cleaning screen frame. A drive motor is fixedly installed on the inner wall of the amplitude adjustment frame. A threaded support rod is fixedly installed at the output end of the drive motor. A threaded sleeve plate is threadedly connected to the surface of the threaded support rod. A limit component is connected to the surface of the threaded sleeve plate. A vibration connecting frame is fixedly connected to the surface of the threaded sleeve plate. A lifting frame with a drive end is fixedly installed on the front side of the vibration connecting frame. An tilting plate is rotatably connected to the inside of the lifting frame through the drive end. A ventilation fan box with a fan is fixedly installed on the top of the cleaning screen frame. A double-layer screen frame is fixedly connected to the bottom of the cleaning screen frame, and a spring telescopic rod is fixedly installed inside the double-layer screen frame.

[0005] 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 surface of the inner wall of the amplitude adjustment frame. The inner wall of the limiting groove and the surface of the limiting slide plate are slidably connected.

[0006] Furthermore, the bottom of the vibration connection frame is a stable base plate, the top of the stable base plate is fixedly installed with a vibration motor, and the output end of the vibration motor is fixedly installed with an upper amplitude frame.

[0007] Furthermore, an anti-vibration telescopic rod with a shock-absorbing spring is fixedly connected to the top of the stable base plate near its side, and the bottom of the upper amplitude frame and the top of the anti-vibration telescopic rod are fixedly installed.

[0008] Furthermore, the two sides of the tilting plate are inclined surfaces, and the surface of the tilting plate is coated with a wear-resistant coating.

[0009] Furthermore, a flow-diverting baffle is fixedly installed on the inner wall of the cleaning screen frame, and the flow-diverting baffle is located directly above the tilting plate.

[0010] Furthermore, a dustproof cloth is fixedly connected to the surface of the amplitude adjustment frame, and the surface of the dustproof cloth is fixedly connected to the bottom of the vibration connection frame, with the outer part of the dustproof cloth sleeved on the outside of the threaded support rod.

[0011] The beneficial effects of this utility model are as follows: The interior of the screen frame allows for material vibration screening. The drive motor rotates the threaded support rod, and the limiting component ensures that the rotation of the threaded support rod moves the threaded sleeve plate. The threaded sleeve plate then moves the vibrating connecting frame on one side, which in turn moves the lifting frame. The drive end of the lifting frame rotates the tilting plate, adjusting its angle. Furthermore, the vibration motor in the vibrating connecting frame moves the upper amplitude frame above it. The connecting lifting frame and tilting plate are then oscillating, allowing the tilting plate to change the distance between itself and the double-layer screen frame, thus adjusting the amplitude of the vibrating material and the angle of the tilting plate. The double-layer screen frame allows for secondary screening of the material after the initial screening. A spring telescopic rod provides shock absorption and stress relief, thereby adjusting the amplitude and tilt angle during the material screening process. A ventilation fan box is added above the cleaning screen frame to remove dust from the interior, ensuring effective screening of the material inside the vibrating cleaning screen.

[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 1-5 This utility model provides a technical solution: A multi-layer vibrating cleaning screen with adjustable amplitude and tilt angle includes a cleaning screen frame 1. An amplitude adjustment frame 2 is fixedly installed inside the cleaning screen frame 1. A drive motor 3 is fixedly installed on the inner wall of the amplitude adjustment frame 2. A threaded support rod 4 is fixedly installed at the output end of the drive motor 3. A threaded sleeve plate 5 is threadedly connected to the surface of the threaded support rod 4. A limit component is connected to the surface of the threaded sleeve plate 5. A vibration connecting frame 6 is fixedly connected to the surface of the threaded sleeve plate 5. A lifting frame 7 with a drive end is fixedly installed on the front side of the vibration connecting frame 6. An adjustment tilt plate 8 is rotatably connected to the inside of the lifting frame 7 through the drive end. A ventilation fan box 9 with a fan is fixedly installed on the top of the cleaning screen frame 1. A double-layer screen frame 10 is fixedly connected to the bottom of the cleaning screen frame 1, and a spring telescopic rod 11 is fixedly installed inside the double-layer screen frame 10.

[0016] Specifically, such as Figures 1-5 As shown, the limiting component includes a limiting slide plate 12 and a limiting groove 13. The limiting slide plate 12 is fixedly connected to the surface of the threaded sleeve plate 5, and the limiting groove 13 is formed on the surface of the inner wall of the amplitude adjustment frame 2. The inner wall of the limiting groove 13 and the surface of the limiting slide plate 12 are slidably connected. By setting the limiting slide plate 12 and the limiting groove 13, the movement trajectory of the threaded sleeve plate 5 is limited, so that the rotation of the threaded support rod 4 can drive the threaded sleeve plate 5 to move.

[0017] Specifically, such as Figures 1-5 As shown, the bottom of the vibration connection frame 6 is a stable base plate, and a vibration motor 14 is fixedly installed on the top of the stable base plate. An upper amplitude frame 15 is fixedly installed at the output end of the vibration motor 14. An anti-vibration telescopic rod 16 with a shock-absorbing spring is fixedly connected to the top of the stable base plate near its side. The bottom of the upper amplitude frame 15 and the top of the anti-vibration telescopic rod 16 are fixedly installed. The operation of the vibration motor 14 in the vibration connection frame 6 can drive the upper amplitude frame 15 to move. Under the action of the anti-vibration telescopic rod 16, it can play a supporting and maintaining role inside the vibration connection frame 6.

[0018] Please refer to Example 2 Figures 1-5 The difference between this embodiment and Embodiment 1 is that the two sides of the tilting plate 8 are inclined surfaces, and the surface of the tilting plate 8 is coated with a wear-resistant coating. The inclined surface of the tilting plate 8 enables angle control and adjustment. A flow diversion baffle 17 is fixedly installed on the inner wall of the cleaning screen frame 1. The flow diversion baffle 17 is located directly above the tilting plate 8, and the flow diversion baffle 17 can provide a blocking and maintenance effect above the tilting plate 8.

[0019] Furthermore, a dustproof cover 18 is fixedly connected to the surface of the amplitude adjustment frame 2. The surface of the dustproof cover 18 is fixedly connected to the bottom of the vibration connection frame 6, and the outside of the dustproof cover 18 is sleeved on the outside of the threaded support rod 4, thereby increasing the protective effect of the dustproof cover 18 on the inside of the amplitude adjustment frame 2.

[0020] The working principle of this utility model is as follows: During use, the cleaning screen frame 1 allows for material vibration screening. The drive motor 3 rotates the threaded support rod 4. The limiting slide plate 12 and limiting groove 13 limit the movement trajectory of the threaded sleeve 5, allowing the threaded support rod 4 to rotate and move the threaded sleeve 5. The operation of the threaded sleeve 5 moves the vibrating connecting frame 6 on one side, which in turn moves the lifting frame 7. The drive end of the lifting frame 7 rotates the tilting plate 8, adjusting its angle. The vibrating motor 14 in the vibrating connecting frame 6 also... The upper amplitude frame 15 can be moved to move, thereby connecting the lifting frame 7 and the tilting plate 8 to swing. This allows the tilting plate 8 to change the distance between itself and the double-layer screen frame 10, achieving the effect of adjusting the amplitude of the vibrating screen material. It also allows the tilting plate 8 to be adjusted in angle. The double-layer screen frame 10 can perform secondary screening of the material after the upper screening. The spring telescopic rod 11 provides shock absorption and force relief, thereby achieving the effect of adjusting the amplitude and tilting angle during the material screening process. A ventilation fan box 9 is added above the cleaning screen frame 1 to suck up the dust inside, ensuring the effect of adjusting the screening process of the internal screening material of the vibrating cleaning screen.
