Grading vibration screening machine

Abstract

The invention discloses a grading vibration screening machine. The screening machine comprises a body (1), a plurality of screen rollers (2), a feeding table (4), a buffering plate (7) and collecting boxes (9); the bottom of the body (1) is provided with a plurality of movable wheels facilitating the quick movement of the body (1); the upper part of the body (1) is provided with a frame body; the feeding table (4) is connected to one side of the frame body; the feeding table (4) is flat, side plates are vertically arranged on two sides of the feeding table (4), the openings of the two sides of the feeding table (4) are different in size, the opening of the big side of the feeding table (4) is outward, and the opening of the small side of the feeding table (4) is positioned at a position connected with the body (1); and the plurality of screen rollers (2) are arranged in parallel in the frame body, the buffering plate (7) is arranged above the middle part of the frame body, and a plurality of collecting boxes (9) are arranged below the frame body. The screening machine is simple in structure and convenient to operate, maintain and replace, and saves the cost and the manpower.

Description

technical field [0001] The field of vibration screening that the present invention relates to, in particular, relates to a vibrating screening machine capable of grading. Background technique [0002] The vibrating screen is a kind of vibrating screening mechanical equipment suitable for dry screening of wet fine-grained and difficult-to-sieve materials. The vibrating screen has the technological characteristics of large amplitude, high vibration intensity, low frequency and elastic screen surface. During the working process, the maximum opening ratio is always maintained, so that the screening efficiency is high, the processing capacity is large, the replacement of the sieve plate is convenient, and the cost is reduced. The large screen surface and large processing capacity of the vibrating screen can meet the production needs of the site. The structure of the vibrating screen adopts a multi-stage screen surface vibration without the screen box and frame not participating...

AI Technical Summary

Problems solved by technology

[0003] Although such a vibrating screen is easy to replace, due to its large structure, the sieve holes on the sieve plate are usually used for screening with different diameters. Therefore, its volume is large, and maintenance and maintenance are difficult, and it is not convenient for quick repair and maintenance.
