Problems solved by technology

However, when this technical solution is applied to the cleaning of the above-mentioned easy-rolling particles, due to the large opening area of ​​the sieve, that is, the ratio of the total area of ​​the sieve to the total area of ​​the sieve is high, some impurities are easy to

Abstract

The invention discloses a composite screen for vibrating sieves, which comprises a base plate with regularly and evenly distributed screen holes, and a flat woven net is pasted on the base plate, and the flat woven net includes a plurality of warp threads and a plurality of weft threads interwoven with each other. In the present invention, a plain woven net including multiple interwoven warp threads and multiple weft threads is pasted on the substrate with regular and evenly distributed screen holes, so that when the particles to be cleaned move on the screen, they are repeatedly blocked by the warp threads and weft threads. The direction and trajectory of the movement are changed by collision to improve the probability and efficiency of falling from the sieve holes into the particle bin; and the warp and weft threads are used to cause the impurities to tilt during the movement, which is more conducive to the rolling of the particles from above the impurities, and is conducive to the complete removal of the particles and impurities. Separation, improve the separation effect; and reduce or prevent impurities from passing through or jamming the sieve hole.

Description

technical field [0001] The invention relates to a vibrating sieve device, in particular to a vibrating sieve screen. Background technique [0002] The sieve of the known vibrating sieve, when cleaning beans, rice, wheat grains, rice and other particles that are easy to roll, and separates them from impurities such as pods, stems, grass clippings, and chaff, the separation effect still exists. insufficient. [0003] For example, a technical solution often used in the vibrating screen, the screen includes a flat base plate, and a plurality of circular screen holes are regularly and evenly distributed on the base plate. When applying the cleaning of the above-mentioned easy-rolling particles, except for the particles that are located below the impurities and whose center of gravity is above the sieve holes, it is easier to escape from the sieve holes, and some other particles, such as those located below the impurities but not above the sieve holes Particles, some particles w...
