Novel self-balanced vibration cleaning sieve

Abstract

The invention discloses a novel self-balanced vibration cleaning sieve which comprises a feeding mechanism, a cleaning mechanism and a self-balancing mechanism, wherein the feeding mechanism and the self-balancing mechanism are connected onto the cleaning mechanism; the feeding mechanism comprises a box body, a shifting fork hub, an auger assembly and a fan; the cleaning mechanism comprises a sieve box, a chain, a scraper plate and a screen; a discharge pipe of the feeding mechanism is in butt joint with a feeding hole of the cleaning mechanism; the self-balancing mechanism comprises two gear discs meshed with each other; and eccentric blocks are fixedly arranged on the gear discs. According to the novel self-balanced vibration cleaning sieve disclosed by the invention, the phenomena that dust is adhered to the sieve surface and sieve pores are blocked are avoided, the oversize product is automatically cleaned, materials are effectively prevented from blocking the meshes by a sweeper, the tension of the screen can be adjusted without a frame, the screen can be rapidly replaced, and the gear discs made by a special design and a portable special material are balanced and do not produce strong vibration so as not to influence the overall structure. By monitoring the rotating speed of the chain wheel, the mechanism has an automatic fault detection function.

Description

technical field [0001] The invention relates to the technical field of grain screening, in particular to a novel self-balancing vibrating cleaning sieve. Background technique [0002] Vibration cleaning equipment currently used in the market basically uses a vibration motor to generate body vibration. Materials move downward on an inclined plane. During the vibration process, debris and finished products are separated. Finally, when the material is discharged, it is sucked by the vertical suction duct. Dust handling dust. [0003] The defects and deficiencies of the existing technology, the working principle is relatively rough and simple, and the cleaning effect and output are not obvious: [0004] A. Uneven feeding: On the one hand, the materials with debris are directly flowed into the screen body through the receiving box (some manufacturers have added a buffer plate), resulting in uneven distribution of materials in the middle and on both sides. When the output increas...

Problems solved by technology

[0005] B. No cleaning mechanism: Almost all vibrating screens on the market cannot automatically clean up the debris on the screen. When the linear debris is entangled on the screen and cannot be cleaned in time, the finished material will often flow with the large impurities. On the one hand, it will affect the separation effect. On the other hand, the output is reduced, so it is necessary to manually clean up the sundries on the sieve

[0006] C. Unstable vibration and loud noise: The box is driven by the vibration motor to vibrate. If the adjustment of the two eccentric blocks is inconsistent, the equipment will vibrate and crack. At the same time, strong noise will be generated, and the screening effect will be poor. For example, the short straw will also be shaken off with the finished product shed together
