Screening device capable of automatically screening sand

Abstract

The invention discloses a screening device capable of automatically screening sand. The screening device capable of automatically screening the sand comprises a transmission case. A base plate is fixedly connected with the bottom of the transmission case, a top plate is fixedly connected with the top of the right side of the transmission case, and an electric box is fixedly connected with the topof the transmission case. A motor which is located inside the electric box is fixedly connected with the top of the top plate. According to the screening device capable of automatically screening thesand, due to the fact that the transmission case, the base plate, the top plate, the electric box, the motor, a first belt pulley, a convex rod, a second belt pulley, a belt, a screening box, supporting mechanisms, first connecting blocks, pull rods, first openings, a concave screening plate, a sliding plate, a sliding groove, a second opening, a handle, a feeding hopper, a discharging pipe and acontrol valve are used cooperatively, the problem that according to an existing screening mode, due to the fact that a screening device is generally shaken manually, the screening efficiency is low issolved, the screening device capable of automatically screening the sand has the advantages of automatically screening the sand and being high in screening efficiency, the labor intensity of a user is reduced, and the screening device capable of automatically screening the sand is conveniently used by persons.

Description

technical field [0001] The invention relates to the technical field of sand screening, in particular to a screening device capable of automatically screening sand. Background technique [0002] Sand refers to fine stone particles, or something shaped like sand, which is a granular material with a particle size of 0.074-2mm that is washed by rain or rolled by rock after weathering. [0003] In construction, road construction, filtration, breeding and beautification, etc., sand is needed. When collecting sand, it is necessary to filter the sand to avoid mixing stones. The existing screening methods are usually through Manual shaking of the sieving device has low sieving efficiency, and such a sieving method has a slow sieving speed during sieving, which increases the labor intensity of the user and is not convenient for people to use. Contents of the invention [0004] (1) Solved technical problems [0005] Aiming at the deficiencies of the prior art, the present invention...
