Technical Field

[0001] The utility model relates to the technical field of anti-blocking of vibrating screens, in particular to an anti-blocking and slag removing device for a closed vibrating screen. Background Art

[0002] A closed vibrating screen is a mechanical device designed for screening and grading materials. Its characteristic is that the entire screening process is carried out in a closed box, which helps to reduce dust pollution and noise pollution while improving work efficiency and safety. When the closed vibrating screen is in operation, an anti-blocking and slag removal device is required to prevent materials from clogging the vibrating screen.

[0003] After searching the Chinese patent "A kind of anti-blocking vibrating screen", the announcement number is "CN220215647U". This patent connects the No. 1 and No. 2 sieve plates at one end to the top through a hanging rope, which can increase the shaking amplitude when the plates vibrate, and a spring is fixedly connected to the other end. The vibration motor can enhance the vibration effect of the No. 1 and No. 2 sieve plates, thereby improving the screening efficiency. Cleaning sweeps are provided at the upper ends of the No. 1 and No. 2 sieve plates, which can be driven by the No. 1 and No. 2 motors to drive the connecting arms to clean the sweeps to prevent the materials from being accumulated for a long time and clogging the sieve openings of the No. 1 and No. 2 sieve plates. The No. 1 and No. 2 sieve plates are arranged on an inclined surface to make it more convenient to discharge the materials. However, the device has a poor effect on cleaning the blocked materials on the vibrating screen, making it inconvenient to quickly clear the vibrating screen, reducing the use effect of the device.

[0004] Therefore, an anti-blocking and slag removing device for a closed vibrating screen is proposed to solve the above problems. Utility Model Content

[0009] Preferably, two second motors are provided on one side of the inner wall of the box, one end of the second motor is fixedly connected to a screw rod, and the screw rod is threadedly connected to the connecting plate to facilitate driving the cleaning roller to move to one end.

[0010] Preferably, two sliders are fixedly connected to both sides of the screen plate, and the sliders are slidably connected to the inner wall of the box. Two compression springs are provided at both ends of the sliders. When the box vibrates, the vibration screen and the compression springs cooperate to improve the vibration effect of the vibration screen and enable it to contact the cleaning roller.

The material blocked on the vibrating screen can be quickly cleaned, thereby improving the use effect of the device.

[0016] 2. By setting up a dredging component, when cleaning the material blocked on the vibrating screen, the mounting plate cooperates with the cleaning plate through several second spring telescopic rods on the inner wall to clean the vibrating screen. The convex points of the cleaning plate can better clean the material. The mounting plate cooperates with the connecting plate through the fixed block. When the cleaning roller moves, it drives the cleaning plate to move to one end, which can quickly clean and dredge the blocked material to prevent the vibrating screen from being blocked.
