A kind of sand screening equipment with crushing function

Abstract

The invention relates to a sand screening equipment with crushing function, which includes a main body, a screen and two supporting blocks, and also includes a crushing mechanism and a discharge mechanism. The crushing mechanism includes a heating box, two first through pipes, two The second duct, two heating assemblies, two lifting assemblies, several auxiliary assemblies and several crushing assemblies, the discharge mechanism includes a branch pipe, an exhaust pipe, a filter screen, a power assembly, two knocking assemblies, two moving components and several fixed blocks, the sand screening equipment with crushing function realizes the function of crushing the agglomerated sand through the crushing mechanism, prevents the agglomerated sand from remaining on the screen, avoids affecting the screening effect, and avoids causing The waste of sand raw materials realizes the function of shaking the discharge pipe through the discharge mechanism, so that the sand inside the discharge pipe can be shaken, the speed of sand discharge is accelerated, and the probability of sand blocking the discharge pipe is reduced, thereby preventing Affect the nesting work.

Description

Technical field [0001] The present invention relates to the field of bridge construction protection, particularly to a sieve sand apparatus having a crushing function. Background [0002] Sand sieving machine, also known as dryland sand sieve boat, sand and gravel separator, is suitable for river channels, reservoirs, coal yard sand and gravel separation equipment. It consists of a hull, a frame, a reducer, a conveyor belt, a rotary screen, an engine or an electric motor. This model is simple in structure, economical and easy to operate. It is divided into drum type sand screening machine, washing drum type sand screen machine, vibrating screen type sand screen machine and so on. [0003] Existing sand screening machine in the sift sand, part of the sieve because of the humid weather and the phenomenon of agglomeration, so that it can not pass through the screen, affecting the work of the sieve sand, not only that, the existing sand sieve machine in the sand discharge, the sand w...

AI Technical Summary

Problems solved by technology

[0003] When the existing sand screening machine is screening sand, some of the sieves are agglomerated due to the wet weather, so that they cannot pass through the screen and affect the sand screening work. Not only that, but when the existing sand screening machine discharges the sand , the sand will concentrate and accumulate at the discharge pipe, which will easily increase the probability of blockage in the discharge pipe, thereby affecting the efficiency of discharge and reducing the reliability of the existing sand screening machine
