Efficient sand screening machine for preventing sieve plate blockage

Abstract

The invention discloses a high-efficiency sand screening machine for preventing blockage of a sieve plate, which comprises a base, an outer frame, an inner frame and a brush holder. In the present invention, by setting the first sieve plate and the second sieve plate, the sand can be graded and screened to meet different use requirements; the left and right reciprocating movement of the outer frame drives the inner frame to vibrate in the left and right directions, and the pulley and The use of the convex surface drives the inner frame to vibrate in the up and down direction, and the sieve plate of the inner frame vibrates in the up and down and left and right directions at the same time. The multi-directional vibration effectively improves the screening efficiency; by setting the static brush holder, it can During the movement of the sieve plate, the sand stuck in the sieve hole is efficiently cleaned to avoid sand blocking the sieve hole and ensure the normal use of the sieve plate.

Description

technical field [0001] The invention relates to a sand screening machine, in particular to a high-efficiency sand screening machine capable of preventing blockage of a screen plate. Background technique [0002] In the construction of construction projects, it is necessary to screen the sand, and screen out the stones and other sundries from the sand to ensure the follow-up work. At this time, it is necessary to use a sand screen machine. The sand is sieved. [0003] During the working process, part of the sand will be stuck in the sieve holes of the sieve plate, which will block the sieve holes in the long run, resulting in the failure of the sieve plate, and most of the existing sand sieving machines do not have a mechanism to solve this problem . Contents of the invention [0004] The object of the present invention is to provide a high-efficiency sand screening machine that prevents the clogging of the sieve plate, so as to solve the problems raised in the above-ment...
