Vibration sieve

Abstract

The invention relates to a vibration sieve, which comprises a sieve plate (1), a sieve framework (2), a vibration supporter (3), vibration buffers (5) and movement stacking assemblies (6), wherein the sieve framework (2) consists of two side plates and a beam (4), the beam (4) is connected with the two side plates, the sieve plate (1) is fixedly arranged at the bottom of the sieve framework (2) and is supported by the bottom beam of the sieve framework (2), the sieve plate (1) is densely provided with sieve holes which enable the to-be-sieved material to fall down, the vibration supporter (3) is used for supporting the sieve framework (2) through the vibration buffers (5), and the movement stacking assemblies (6) are respectively arranged between the vibration supporter (3) of the vibration sieve and the side plates of the sieve framework (2) of the vibration sieve so as to change the vibration track of the sieve framework (2). By arranging the movement stacking assemblies, the degree of freedom of the sieve framework is controlled, and the material groups on the sieve plate are sufficiently loosened and rearranged under the actions of inertia of the material groups and backward driving of the sieve framework, so the conveying capability is increased.

Description

technical field [0001] The invention belongs to the field of vibrating screening machinery, in particular to a vibrating screen, in particular to a linear vibrating screen with improved motion track. Background technique [0002] The production capacity of the vibrating screen currently used in the market depends on the moving speed of the material along the screen surface, and the moving speed is too large or too small to be detrimental to the screening effect.

When adjusting the sieve, the most suitable moving speed of the material along the screen surface can only be determined experimentally. In many cases, the moving speed of the material is adjusted by changing the inclination angle of the screen surface; on-site adjustment is inconvenient.

[0002] The production capacity of the vibrating screen currently used in the market depends on the moving speed of the material along the screen surface, and the moving speed is too large or too small to be detrimental to the screening effect. If the moving speed is too high, the screening efficiency will be reduced. Affect the production capacity of the sieve

When adjusting the sieve, the most suitable moving speed of the material along the screen surface can only be determined experimentally. In many cases, the moving speed of the material is adjusted by changing the inclination angle of the screen surface; on-site adjustment is more inconvenient

In addition, this type of sieve cannot fully loosen and rearrange the materials in actual use, so the fine-grained materials are not easy to approach the screen surface and cannot achieve the corresponding screening effect, and at the same time, the particles that have blocked the sieve holes are not easy to be thrown out. , so that the screening process is further deteriorated, and the corresponding screening effect cannot be achieved.

[0003] In addition, since the movement trajectory of the vibrating screen is related to many factors, any increase or adjustment of any fulcrum on the screen frame will affect the movement trajectory of the material on the sieve plate and thus affect the performance of the vibrating screen.
