Mobile automatic sand screening device

Abstract

A movable automatic sand screening device, comprising a bottom plate, two universal wheels are fixedly connected to one side of the bottom of the bottom plate, a handle is fixedly connected to one end of the bottom plate close to the universal wheels, and a handle is fixedly connected to the bottom end of the second support column. There is a shock-absorbing and anti-pressure device, the inside of the screen box is provided with a screen, the side of the outer wall of the screen box is provided with a tooth groove, the inside of the tooth groove is provided with a half gear, and the half gear is fixedly connected to a second gear through a transmission device. A motor, the middle part of the third support column is provided with a hydraulic lifting mechanism, and the outer wall of the side of the bottom plate away from the first support column is fixedly connected with a screw lifting mechanism through the first connecting rod and the second connecting rod. The present invention relates to In the technical field of mechanical equipment, this mobile automatic sand screening device achieves the advantages of convenient movement of the device, shock absorption and pressure resistance, more sufficient sand screening, automatic feeding, no need for manual feeding, saving time, and fine sand after screening. The sand and coarse sand flow separately without interfering with each other.

Description

technical field [0001] The invention relates to the technical field of mechanical equipment for construction, in particular to a movable automatic sand screening device. Background technique [0002] Sand screening is an inevitable process in the construction process. It is a job to separate coarse sand from fine sand. However, the work of sand screening is boring and hard. The existing mechanical sand screening machines are all manual. The sand efficiency is low, and it is easy to cause physical damage to the staff, while the manual sand screening efficiency is low and the speed is slow, which affects the work process. Easy to carry. Contents of the invention [0003] (1) Solved technical problems [0004] Aiming at the deficiencies of the prior art, the present invention provides a movable automatic sand screening device, which solves the problems that the existing sand screening machines need to manually screen sand, and the working process is unsafe, inefficient, and...
