[0036] It should be noted that similar labels and letters in the following figures indicate similar items; therefore, once an item is defined in one figure, it does not need to be discussed further in subsequent figures.

[0037] See Figure 1 This utility model discloses an automatic cleaning device for material on a vibrating screen, including a vibrating screen 4, a first hopper 12, a second hopper 6, a guide plate 15, a drive motor, a telescopic component, a weighing sensor 7, a material detection device, and a control system, which is controlled by a PLC.

[0038] The vibrating screen 4 is mounted on the vibrating screen base 5. The vibrating screen 4 contains two layers of screens 13, including a first screen and a second screen arranged sequentially from top to bottom inside the vibrating screen 4. The side wall of the vibrating screen 4 has a first discharge port 9, a second discharge port 20, and a third discharge port 10. The first discharge port 9 is located above the first screen, the second discharge port 20 is located between the second screen and the first screen, and the third discharge port 10 is located below the second screen. A second hopper 6 is connected to both the first discharge port 9 and the second discharge port 20, and is used to receive the oversize material above the first and second screens; that is, the second hopper is used to receive the oversize material from the vibrating screen 4. A first hopper 12 is connected to the third discharge port 10 and is used to receive the undersize material from the vibrating screen 4. The first hopper 12 has a volume of 30L~50L.

[0039] Combination Figure 2 and Figure 3The first discharge port 9 is equipped with a first gate, and the second discharge port 20 is equipped with a second gate. The first gate and the second gate have the same structure, both including: a gate plate control cylinder 17, a gate plate 14, two gate plate guide grooves 18 arranged opposite to each other on both sides of the width of the first discharge port 9, and a gate plate sealing groove 19 located at the bottom of the first discharge port 9. The free end of the gate plate control cylinder 17 is connected to the gate plate to drive the gate plate to perform opening and closing movements. That is, the gate plate control cylinder 17 can drive the gate plate 14 to move up and down in the two gate plate guide grooves 18. When the first gate and the second gate are closed, the two sides of the width of the gate plate 14 are respectively inserted into and sealed with the two gate plate guide grooves 18, and the bottom edge of the gate plate 14 is inserted into the gate plate sealing groove 19.

[0040] The vibrating screen 4 is also equipped with an ultrasonic sensor 1 as a material detection device, which is used to detect the material remaining above the screen 13. Weighing sensors 7 are installed on the first hopper 12 and the second hopper 6. The ultrasonic generator field box 3 is electrically connected to the ultrasonic sensor 1, the ultrasonic generator field box 3 is electrically connected to the ultrasonic sensor control box, and the ultrasonic sensor control box 2 is electrically connected to the control system.

[0041] A guide plate 15 is installed inside the vibrating screen 4 and above the screen 13, with one guide plate 15 installed above each of the two screens 13. The guide plate 15 is used to guide the material on the screen 13 to the first discharge port 9. The telescopic assembly includes a guide plate control cylinder 16, the free end of which is connected to the guide plate 15. When the guide plate control cylinder 16 is extended, it moves the guide plate 15 to the working position. When the guide plate control cylinder 16 is retracted, it moves the guide plate 15 to the standby position. One end of the guide plate 15 in the working position is hinged to the inner wall of the vibrating screen 4, and the other end is spaced apart from the inner wall of the vibrating screen 4, forming an angle between the guide plate 15 and the inner wall of the vibrating screen 4. The guide plate 15 includes a receiving surface, which faces the material movement direction above the screen 13 when the drive motor 11 reverses. Specifically, the inner wall of the vibrating screen 4 is cylindrical, and the guide plate 15 is an arc-shaped plate. When the guide plate 15 is in the standby position, the side of the guide plate 15 facing away from the material receiving surface is completely attached to the inner wall of the vibrating screen 4, which will not affect the normal operation of the vibrating screen 4.

[0042] The drive motor 11 is connected to the vibrating screen 4; the control system is electrically connected to the drive motor and the gate control cylinder 17 respectively, and the control system can control the drive motor to rotate forward and reverse.

[0043] (1) Working principle: During the use of the equipment, the material enters from the top feed port of the vibrating screen 4, and is filtered by two layers of screens 13. The screened material is discharged into the first silo 12 through the third discharge port 10. After a certain period of operation, the vibrating screen 4 needs to automatically clean the material on the screen. At this time, the gate plate control cylinder 17 drives the gate plate 14 to lift and open the first discharge port 9 and the second discharge port 20. The guide plate control cylinder 16 runs the guide plate 15 to open, and the drive motor 11 reverses to run. The material on the screen is discharged into the second silo 6, thus realizing the design function of the system.

[0044] (2) Working process: After running for a certain period of time, the vibrating screen 4 needs to automatically clean the material on the screen. At this time, the gate plate control cylinder 17 drives the two gate plates 14 to lift and open the first discharge port 9 and the second discharge port 20. The guide plate control cylinder 16 runs the guide plate 15 to open. The drive motor 11 runs in reverse and the material on the screen is discharged to the second hopper 6. When the material is discharged, the ultrasonic sensor 8 detects that the material on the screen has been discharged. The drive motor 11 reverses and stops, closes the guide plate 15 and the gate plate 14, and the drive motor 11 rotates forward to start the next cycle of feeding and screening, thereby realizing the design function of the system.

[0045] (3) Product function: Automatically cleans the material that needs to be discharged from the upper and lower screens of the vibrating screen, so as to achieve unmanned cleaning.

[0046] (4) Operation steps: Start the equipment and the system will automatically detect when the first hopper 12 and the second hopper 6 are at low material levels. The system will run automatically and the program will automatically execute according to the set cleaning screen feeding time. If an abnormality is found during the operation, the system will automatically alarm and stop. After the staff monitors and eliminates the equipment problem, the system will be started and the equipment will run normally.

[0047] In summary, the automatic cleaning device for the screen of the vibrating screen provided by this utility model opens the gate plate and guide plate by operating a cylinder when screen discharge is required. After the gate plate and guide plate are opened to the designated position, the vibrating screen is started in reverse, and the material is discharged from the top of the screen through the discharge port, thus realizing the function of automatic discharge. Furthermore, due to the dew point requirements of some materials, the original manual cleaning of the screen required opening the screen frame and using a brush to clean the material on the screen surface, which easily caused changes in the dew point within the system. This improvement allows the dew point within the equipment to be controlled towards a stable target, maximizing the quality control of the finished material. The design of the gate plate, gate plate guide groove, and gate plate sealing groove effectively seals the discharge and material inlet; the motor reverses to collect and store the screen material; the material stored in the screen hopper can be collected or back-feeded to the upstream hopper for reuse.

[0048] Although specific embodiments of the present invention have been described in detail by way of examples, those skilled in the art should understand that the above examples are for illustrative purposes only and are not intended to limit the scope of the present invention. Those skilled in the art should understand that modifications can be made to the above embodiments without departing from the scope and spirit of the present invention. The scope of the present invention is defined by the appended claims.
