Construction sand screening machine

Abstract

The invention discloses a construction sand screening machine which comprises a machine body. The top of the machine body communicates with a feed hopper. A first motor is fixedly mounted at the top of the right side of the machine body. The output end of the first motor penetrates through the machine body and extends into the machine body to be fixedly connected with a rotary shaft. Stirring rods are fixedly mounted on the surface of the rotary shaft. A bearing is movably connected with the left side of the rotary shaft. The left side of the bearing is fixedly connected with the left side of the inner wall of the machine body. A second motor is fixedly mounted on the portion, under the first motor, of the right side of the machine body. According to the construction sand screening machine, the leakage problem when sand falls to a secondary sieve from a primary sieve can be effectively avoided through a first baffle and a second baffle, screening can be effectively conducted through cooperation of the secondary sieve, a disc and a third motor, the screening effect of the coarse sand and the fine sand can be better through arrangement of the primary sieve and the secondary sieve, and therefore the problem of low screening efficiency is solved.

Description

technical field [0001] The invention relates to the technical field of sand screening, in particular to a sand screening machine for construction. Background technique [0002] Sand is generally divided into two types: natural sand and artificial sand. The rock particles formed by natural conditions are mainly rock weathering, called natural sand. Artificial sand is crushed from rock. Due to high cost, flake and powder There are many things, generally not used. [0003] In the existing construction industry, a large amount of sand needs to be used, and coarse sand and fine sand need to be screened before use, but the existing sand screening machine is not effective in screening sand, and cannot properly screen coarse sand and fine sand. Screening, resulting in low screening efficiency. Contents of the invention [0004] The object of the present invention is to provide a sand screening machine for construction, which has the advantages of good sand screening effect and s...
