Vibrating screen is widely used in mining, metallurgy, chemical industry, building materials, food and other industries, with the advantages of high screening efficiency, simple operation and convenient maintenance.

[0003] When the vibrating screen is in use, the screen is generally fixed in the vibrating screen, and it is impossible to select a reasonable screen according to the diameter of the material to be screened, resulting in a limited screening range. Utility Model Content

[0004] In order to increase the screening range of the vibrating screen, the present application provides an adjustable high-frequency vibrating screen.

The upper pressing frame and the lower pressing frame cooperate to clamp the screen, and the fixing component fixes the upper pressing frame and the lower pressing frame again to maintain the stability of the screen. The vibration mechanism drives the screen to vibrate, thereby completing the screening work.

[0009] By adopting the above technical solution, the fixing nut is loosened so that the fixing nut is away from the upper fixing block, and then the fixing rod is rotated so that the fixing rod and the fixing nut are away from the upper fixing block, so that the upper pressure frame and the lower pressure frame can be separated, and then the screen is disassembled and assembled. After the screen is replaced, the screen is clamped again by the upper pressure frame and the lower pressure frame, and the upper pressure frame and the lower pressure frame are fixed again by the fixing assembly.

A screen 8 is provided between the upper pressing frame 21 and the lower pressing frame 22.

[0031] The fixing assembly 3 fixedly connects the upper pressing frame 21 and the lower pressing frame 22, so as to keep the screen 8 stable. The vibration mechanism 9 drives the screen 8 to vibrate, thereby completing the screening work.

[0032] The fixing assembly 3 includes an upper fixing block 31 and a lower fixing block 32. The upper fixing block 31 is fixedly connected to the upper pressing frame 21, and the lower fixing block 32 is fixedly connected to the lower pressing frame 22. The upper fixing block 31 and the lower fixing block 32 are both configured in a U shape. A fixing rod 33 is hinged at the opening of the lower fixing block 32. One end of the fixing rod 33 away from the lower fixing block 32 rotates to the opening of the upper fixing block 31. A fixing nut 34 is also threadedly connected to the fixing rod 33. The fixing nut 34 abuts against the upper end surface of the upper fixing block 31.

[0033] Loosen the fixing nut 34 so that the fixing nut 34 moves away from the upper fixing block 31, and then rotate the fixing rod 33 so that the fixing rod 33 and the fixing nut 34 both leave the upper fixing block 31, so that the upper pressing frame 21 and the lower pressing frame 22 can be separated, and the screen 8 is placed on the side of the lower pressing frame 22 close to the upper pressing frame 21, and then rotate the upper pressing frame 21 so that the upper pressing frame 21 presses the screen 8 against the lower pressing frame 22, thereby clamping the screen 8 again, and the fixing rod 33 is rotated to the opening of the upper fixing block 31 again, and the fixing nut 34 is tightened to fix the upper pressing frame 21 and the lower pressing frame 22.
