Sand screening equipment for construction

Abstract

The invention discloses sand screening equipment for construction. The sand screening equipment comprises a sand screening box, an electric push rod, a first screen, a second screen, springs, a first gear, a second gear, an incomplete gear, a first rotary shaft, a first motor, a first bevel gear, a second bevel gear, a second rotary rod, cross rods, brushes, a reel and a second motor. The sand screening equipment is provided with the first screen and the second screen, and multi-stage screening can be conducted to meet requirements of different construction operations; the sand screening equipment is provided with the first motor, the first rotary shaft, the incomplete gear, the first gear, the second gear and the springs, the first screen and the second screen are made to shake continuously through cooperation, and the sand screening efficiency is improved; the sand screening equipment is provided with the first bevel gear, the second bevel gear, the second rotary shaft, the cross rods and the brushes, the bottom of the first screen and the top of the second screen are brushed continuously through the brushes, meshes of the first screen and the second screen are prevented from being blocked, and the sand screening efficiency is further improved; and the sand screening equipment is provided with the electric push rod, the reel and the second motor, and discharging is convenient.

Description

technical field [0001] The invention relates to the technical field of construction equipment, in particular to sand screening equipment for construction. Background technique [0002] Sand is an essential basic raw material in the field of construction. There are many impurities in the sand, such as gravel, garbage, etc., and the sand in the sand is also divided into different grades for different purposes. The required sand particle size grade different. Therefore, it is necessary to sieve the sand before using it. [0003] The current sand screening equipment generally only has the first-level sand screening function, which cannot meet the needs of different construction operations, and the screen mesh is easily blocked during the screening process, and the sand screening efficiency is low, which increases the labor intensity of workers and reduces work efficiency. Contents of the invention [0004] The object of the present invention is to provide a construction sand...
