specific Embodiment approach 1

[0033] A fine sand screening device capable of automatically discharging coarse sand, comprising a sand inlet cylinder assembly 1, a rotating disk assembly 2, a sand screening assembly 3, a coarse sand collection assembly 4, a sand screening drive assembly 5 and a mounting frame assembly 6, the present invention A fine sand screening device that can automatically discharge coarse sand, its working principle is: when in use, first connect the sand screening drive assembly 5 to the power supply and turn it on through the control switch, and then pour it into the sand inlet assembly 1 Enter the sand that needs to be screened. After the sand falls into the sand screen assembly 3 through the sand inlet tube assembly 1, it will move clockwise under the drive of the rotating disc assembly 2, and the fine sand will be screened through the sand screening assembly 3. After the fine sand is sieved, the remaining coarse sand falls into the inside of the coarse sand collection assembly 4, w...

Abstract

The present invention relates to a screening device, in particular to a fine sand screening device capable of automatically discharging coarse sand, comprising a sand feeding cylinder assembly, a rotating disk assembly, a sand screening assembly, a coarse sand collection assembly, a sand screening drive assembly and The installation frame assembly, the sand inlet barrel assembly includes the sand inlet barrel body, the sand falling pipe, the sand rotating anti-blocking device, the upper supporting plate, the fixing column and the lower supporting plate; the lower end of the sand inlet barrel body is welded and connected to the falling Sand pipe; the lower end of the sand rotating anti-blocking device is connected to the inside of the sand inlet barrel body in rotation, and the upper end of the sand rotating anti-blocking device is connected to the upper supporting plate in a rotating fit, and the lower end of the upper supporting plate is fixed by The column is connected to the lower supporting plate; the sand falling pipe is connected to the lower supporting plate through threads. The invention can effectively solve the problem that the sand screening device in the prior art cannot automatically discharge the remaining coarse sand after fine sand screening; the invention can automatically discharge the coarse sand without manual cleaning, and its sand screening efficiency is high, and Sand works better.

Description

technical field [0001] The invention relates to a screening device, in particular to a fine sand screening device which can automatically discharge coarse sand. 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. Sand screening device, also known as dry land sand screening ship, sand and gravel separator, is a sand and gravel separation equipment suitable for rivers, reservoirs, coal yards and buildings. The screening machine is divided into drum sand screening machine, washing drum sand screening machine, vibrating screen sand screening machine etc. The sand sieving machine imitates the working principle of artificially using the inclined screen to screen sand....
