A high-efficiency sand screening device of shaking and impacting type

Abstract

The invention discloses a high-efficiency shaking and impacting sand screening device, which comprises a frame body and a sand screening frame; There is a feeding port at the position corresponding to the screen hole, and horizontal fixing plates are symmetrically arranged on the bottom of both sides of the sand screening frame; a motor is installed on the left side of the bottom surface of the inner cavity of the frame, and the output end of the motor is connected to a transmission shaft. The outer periphery of the shaft body of the transmission shaft is fixed with a first L-shaped rod. The end of the vertical rod body of the first L-shaped rod is connected to the bottom of the fixed plate on the left through the first bearing. A vertical shaft and a second L-shaped rod are provided; a plurality of elastic connectors are fixed equidistantly along the circumferential direction on the side wall of the inner cavity of the frame body, and impact blocks are connected to the ends of the elastic expansion parts. The invention screens sand and gravel in a shaking and impacting manner, which can effectively improve the screening effect and avoid waste of sand and gravel.

Description

technical field [0001] The invention relates to a sand screening device, in particular to a high-efficiency shaking and impact sand screening device. Background technique [0002] Civil engineering is a general term for the science and technology of building various engineering facilities. It not only refers to the applied materials, equipment and technical activities such as survey, design, construction, maintenance and repair, but also refers to the object of engineering construction. That is, various engineering facilities built on the ground or underground, on land or in water, that directly or indirectly serve human life, production, military affairs, and scientific research, such as houses, roads, railways, pipelines, tunnels, bridges, canals, dams, ports, Power stations, airports, offshore platforms, water supply and drainage, and protection projects, etc. [0003] In the field of civil engineering, sand screening devices are often used to screen sand and gravel.
