Springs are fixedly installed at the four corners of the upper surface of the base, and the dewatering screen frame is installed above the springs. Although the above technical solution solves the problem of screen clogging, the following problems still exist: The above technical solution controls the brush roller to rotate through a second motor, but during the operation of the vibrating screen, the power supply line needs to follow the reciprocating motion, which will cause the line to wear to varying degrees, thus posing a risk of leakage.

[0003] Therefore, this application provides an anti-clogging high-frequency vibrating dewatering screen to meet the requirements. Utility Model Content

[0004] The purpose of this application is to provide an anti-clogging high-frequency vibrating dewatering screen, which aims to solve the problem that the power supply line is prone to contact with the base or bottom surface during the reciprocating motion of the brush roller driven by a motor, which leads to accelerated wear and reduced service life.

[0005] To achieve the above objectives, this application provides the following technical solution: a high-frequency vibrating dewatering screen for clogging prevention, comprising a base, a screen body, and a screen mesh. The screen body is provided on the top surface of the base, and the screen mesh is provided on the screen body.

[0007] The cleaning mechanism also includes a motor, a fixed base, a moving rod, a moving block, and a brush roller. The fixed base is installed on the top surface of the screen body. There are two sets of fixed bases, which are symmetrically arranged. A sliding groove is provided on the top surface of the fixed base. The moving rod is rotatably connected in the sliding groove, and the moving rod is threadedly connected to the moving block. A support plate is detachably installed on the moving block. The two sets of support plates are connected by the brush roller, and the brush roller is slidably connected to the bottom of the screen. A motor is provided on the screen body, and the motor is connected to the moving rod.

[0008] Preferably, the support plate is provided with a gear coaxial with the brush roller, and a rack is provided on the bottom surface of the support member, with the rack and gear meshing with each other.

[0009] Preferably, a draining element is provided on the bottom surface of the support member, and the draining element is inclined.

[0010] Preferably, the top surface of the support member is provided with a guide member, and the cross-section of the guide member is wedge-shaped.

[0011] Preferably, the cleaning mechanism includes a crossbeam and cleaning components. The crossbeam connects two sets of support plates and has a T-shaped cross-section.

[0024] 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.

[0025] Example: Reference Figure 1-6 The illustrated anti-clogging high-frequency vibrating dewatering screen includes a base 1 and a screen body 2. The screen body 2 is mounted on the base 1, and a support member 3 for placing a screen mesh 7 is provided on the inner wall of the screen body 2. The support member 3 has an L-shaped cross-section, and a cleaning mechanism is provided below the screen mesh 7. During operation, the cleaning mechanism cleans the screen mesh 7 from the bottom to prevent clogging. In order to prevent the cleaning mechanism from accumulating some impurities during the cleaning process, which would affect the cleaning mechanism's performance, a cleaning mechanism is provided on the cleaning mechanism to perform the cleaning task.

[0026] Cleaning mechanism: Two sets of symmetrical fixed seats 9 are provided below the screen body 2 (top surface of the base 1), and a sliding groove 91 is provided on the top surface of the fixed seat 9. A moving rod 10 is provided in the sliding groove 91. The moving rod 10 is a threaded rod, and the moving block 11 slides in the sliding groove 91. In order to control the operation of the moving rod 10, a motor 8 that can drive the moving rod 10 is provided on one side of the fixed seat 9. The moving block 11 is threadedly connected to the moving rod 10, and the moving block 11 has a T-shaped structure. A support plate 12 is fixed to the horizontal section of the moving block 11 by bolts. The two sets of support plates 12 are connected by a brush roller 13, and the brush roller 13 is slidably connected to the bottom of the screen 7. Under the drive of the motor 8, the brush roller 13 is controlled to reciprocate and clean the bottom of the screen 7.

[0027] In the above-mentioned cleaning mechanism, in order to ensure the cleaning efficiency of the brush roller 13, a set of racks 5 are installed at the bottom of the support member 3, and a gear 14 coaxial with the brush roller 13 is provided on the support plate 12. The gear 14 meshes with the rack 5. Therefore, when the motor 8 drives the moving rod 10 to work, causing the moving block 11 to rotate in the slide groove 91, the brush roller 13 will automatically rotate, thereby improving the cleaning efficiency and avoiding clogging.

[0028] Cleaning mechanism: The cross section of the beam 15 is T-shaped, and the two ends of the two sets of beams 15 are connected to the opposite surfaces of the support plate 12. At the vertical section of the beam 15, a cleaning component 16 is fixed by bolts. The cleaning component 16 is comb-shaped and has an arc-shaped cross section. Through the structure of the cleaning component 16, the brush on the brush roller 13 can be cleaned during operation. Since the cleaning component 16 is arc-shaped, some impurities flow on the cleaning component 16 during use and are discharged through the perforation 161.

[0029] To avoid leaving impurities on the crossbeam 15, an arc-shaped strip is provided on the top surface of the crossbeam 15, and the two sides of the arc-shaped strip are connected to the edges of the front and rear perforations 161 respectively.

[0030] To prevent materials from falling onto the support member 3 during operation, a set of guide members 4 are provided on the support member 3. The cross-section of the guide members 4 is wedge-shaped, so that the falling materials are directly or diverted onto the screen 7. In addition, to protect the sliding groove 91 of the fixed seat 9 below, an inclined diverting member 6 is provided at the bottom of the support member 3.

[0031] The working principle of this practical system is as follows: By starting the vibrating screen, the screen body 2 operates on the base 1. Material is then fed in and falls onto the screen mesh 7 (the guide 6 is designed to direct the material onto the screen mesh 7). After a certain period of operation, when maintenance of the screen mesh 7 is required, the motor 8 is started. The motor 8 drives the moving rod 10 to rotate within the slide groove 91. With the cooperation of the thread and the slide groove 91, the moving rod 10 drives the moving block 11 to reciprocate on the fixed base 9. During this process, the gear 14 meshes with the rack 5, thus rotating automatically. The gear 14 drives the brush roller 13, which meshes with it, to rotate on the support plate 12, thereby cleaning the screen 7. During this process, the brush on the brush roller 13 comes into contact with the cleaning component 16. The structure of the cleaning component 16 cleans the brush. When some impurities fall to the top surface of the cleaning component 16, they fall to the perforation 161 under the action of the arc surface and are discharged. The arc strip on the top surface of the crossbeam 15 prevents impurities from being retained on the top surface of the crossbeam 15. The guide 6 at the bottom of the support component 3 protects the fixed seat 9 and prevents impurities from falling into the chute 91.

[0033] Components not described in detail in this article are existing technologies.

[0034] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
