Intermittent feeding type sand sieving device for building

Abstract

The invention discloses an intermittent feeding type sand sieving device for building. The intermittent feeding type sand sieving device comprises a storage cavity and a sieving cavity and is characterized in that the storage cavity is arranged at the upper end of the left side of the sieving cavity and communicated with the sieving cavity through a discharge outlet, a transverse plate is fixedlymounted in the sieving cavity, the inner side of the transverse plate is provided with a circular cavity, a first eccentric wheel is arranged on the inner side of the circular cavity, push rods are symmetrically arranged at the left end and the right end of the first eccentric wheel, fixing parts are mounted at the lower ends of the push rods, the lower ends of the fixing parts are hinged to one ends of the connecting rods, and the other ends of the connecting rods are hinged to the upper end of a sieve plate. The intermittent feeding type sand sieving device has the advantages that the deviceis novel in design, a second eccentric wheel rotates to drive a retaining plate to move vertically in a reciprocating manner to intermittently open the discharge outlet so as to achieve intermittentfeeding, and accordingly the sieving effect can be effectively prevented from being affected by the fact that excessive sand enters the sieving cavity at the same time; the push rods move leftwards and rightwards to drive the sieve plate to swing in a reciprocating manner through the connecting rods, and accordingly the sieving efficiency of the sieve plate is increased, and high practicality is achieved.

Description

technical field [0001] The invention relates to the field of construction machinery, in particular to an intermittent feeding sand screening device for construction. Background technique [0002] Sand is one of the most important raw materials in the construction industry. When using sand, it is hoped that the size of the sand will be uniform, but the sand fished from the river or sand mined by other methods has different sizes, and there are also mixed sizes. gravel, which requires sand screening; at present, most construction sites still use artificial sand screening, which is labor-intensive for construction workers, and the efficiency of sand screening is low, and the effect of sand screening is poor. [0003] Sand screening machine, also known as dry land sand screening ship, sand and gravel separator, is a sand and gravel separation equipment suitable for rivers, reservoirs, and coal yards. It consists of hull, frame, reducer, conveyor belt, rotary screen, engine or m...
