Vibration sieve capable of adjusting sieve pores

Abstract

The invention discloses a vibration sieve capable of adjusting sieve pores. The vibration sieve comprises an outer framework, an outer sieve net, an inner framework and an inner sieve net, wherein the outer sieve net and the inner sieve net are identical in structure, the outer sieve net and the inner sieve net are respectively arranged in the outer framework and the inner framework, wires of the outer sieve net and the inner sieve net respectively form a 45-degree angle with the outer framework and the inner framework, inner sides of two wide rods of the outer framework are respectively provided with a slide groove with two closed ends, the inner framework is arranged in the slide groove, the length of the slide groove is greater than the length of each wide rod of the inner framework, and the outer side of the wide rod of the outer framework is provided with a fixing device for fixing the position of the inner framework. According to the vibration sieve with adjustable sieve pores, the inner framework and the inner sieve net slide, so that the inner sieve net and the outer sieve net are staggered, and the sieve pores of the vibration sieve are smaller; when the inner sieve net is not required to be reduced, the inner framework can be moved to an original position, and the vibration sieve can be larger; the size of the sieve pore can be adjusted without replacing the vibration sieve.

Description

technical field [0001] The invention relates to a vibrating screen, in particular to a vibrating screen with adjustable screen holes. Background technique [0002] The vibrating screen uses the vibration of the vibration motor as the vibration source, so that the material is thrown up on the screen, and at the same time moves forward in a straight line. The oversize and undersize are discharged from their respective outlets. The degree of screening materials by the vibrating screen is directly related to the size of the screen hole of the vibrating screen; the size of the screen hole of the traditional vibrating screen cannot be adjusted. When different materials need to be screened, only the screen can be replaced, which is difficult to operate. SUMMARY OF THE INVENTION [0003] The purpose of the present invention is to provide a vibrating screen with adjustable screen hole in order to solve the above problems. [0004] The present invention realizes above-mentioned pu...
