Material screening machine

Abstract

The invention discloses a material screening machine. The material screening machine comprises a machine case, a screening chamber, a discharge chamber and a residue discharge chamber, wherein the screening chamber, the discharge chamber and the residue discharge chamber are arranged in the machine case; a driving assembly is arranged outside the machine case; the screening chamber and the discharge chamber are separated through a roller screen fixed to the interior of the machine case; the screening chamber and the residue discharge chamber are separated through a discharge roller hinged to the interior of the machine case; a screening plate frame is hinged to the interior of the screening chamber; a plate frame connecting shaft of the screening plate frame is connected with the driving assembly, so that the driving assembly drives a plate frame body of the screening plate frame to rotate inside the screening chamber; and the plate frame connecting shaft is connected with a dischargeroller connecting shaft through a transmission assembly. The material screening machine provided by the embodiment of invention is reasonable in structure design, can implement the screening process well, has the advantages of being small in size and light in structure and facilitates design layout of a production line.

Description

technical field [0001] The invention relates to the field of screening equipment, in particular to a material screening machine. Background technique [0002] The process in which the broken material is divided into different particle sizes through one or several layers of sieve surface is called screening. The sieving machine uses the relative movement between the granular material and the sieve surface to make part of the particles pass through the sieve holes, and the sand and gravel Materials such as gravel and gravel are divided into different levels of vibrating screening machinery and equipment according to particle size. The screening process of the screening machine is generally continuous. Through the sieve hole, it is called the under-sieve product; the material larger than the size of the sieve hole is continuously discharged from the sieve surface, called the over-sieve product. [0003] In the existing material screening machine, there is a problem of unreason...
