Description

Technical Field

[0001] This utility model relates to the field of grain screening technology, specifically a vibrating screen with a convenient adjustable screen tilt angle. Background Technology

[0002] A vibrating screen operates by utilizing the complex rotary vibration generated by a vibrator. The screening accuracy of a vibrating screen depends not only on the vibration frequency and the mesh size of the screen, but also on the screen's tilt angle. This is because, given the same vibration frequency and mesh size, a larger tilt angle (steeper slope) results in shorter grain passage time and lower screening accuracy; conversely, a smaller tilt angle (gentler slope) results in longer grain passage time and higher screening accuracy. Furthermore, different grain sizes and impurities require different screening accuracies, necessitating adjustment of the screen's tilt angle based on actual usage. Existing vibrating screens with adjustable tilt angles suffer from limitations in achieving arbitrary tilt angle adjustment within a certain range, and also exhibit higher noise levels due to the adjustable screen vibration caused by the tilt angle. Summary of the Invention

[0003] To address the problem that the tilt angle of the screen cannot be arbitrarily adjusted within a certain range in the existing technology, and to solve the problem that the existing vibrating screens with adjustable screen tilt angles have high noise during operation, this utility model proposes a vibrating screen with a convenient adjustable screen tilt angle.

[0004] The present invention relates to a vibrating screen with convenient adjustable screen tilt angle, comprising a screen body and a screen; the screen is fixed around its perimeter within a square screen frame; the rear end of the screen frame is rotatably connected via rotating shafts fixed on the left and right sides of the screen body; vertical bolt fixing holes are respectively provided on the left and right sides of the front side of the screen body; bolts corresponding to the bolt fixing holes are fixedly provided on the front end of the screen frame, the bolts are used to pass through the bolt fixing holes, and an outer nut is provided on the bolt located on the outside of the screen body.

[0005] The vibrating screen of this utility model, which allows for convenient adjustment of the screen tilt angle, can be adjusted within a certain range by moving the bolts up and down within the bolt fixing holes to meet the different screening accuracy requirements of grains with different particle sizes and impurities.

[0006] The bolt is also equipped with an inner nut located inside the screen body to better secure the bolt in its adjusted position.

[0007] Rubber gaskets are provided between the outer nut and the outer surface of the screen body, and between the inner nut and the inner surface of the screen body, to reduce the loosening of the nuts and reduce the operating noise of the vibrating screen.

[0008] A shock-absorbing rubber ring is installed between the rotating shaft and the rear screen frame to reduce the operating noise of the vibrating screen.

[0009] The present invention relates to a vibrating screen with a convenient adjustable screen tilt angle. The screen tilt angle can be adjusted within a certain range by adjusting the upper and lower positions of the bolts in the bolt fixing holes, so as to meet the different screening accuracy requirements of grains with different particle sizes and impurities. Furthermore, by adding rubber pads and rubber rings, the noise of the vibrating screen with adjustable screen tilt angle during operation is reduced. Attached Figure Description
