Shaking impact type efficient sand screening device

Abstract

The invention discloses a shaking impact type efficient sand screening device. The shaking impact type efficient sand screening device comprises a frame body and a sand screening frame; the sand screening frame is arranged in the frame body, sieve meshes are uniformly distributed in a bottom plate of the sand screening frame, the position, corresponding to the sieve meshes, of the frame body is provided with a discharging outlet, and transverse fixed plates are symmetrically arranged at the bottoms of the two sides of the sand screening frame; a motor is installed on the left side of the bottom face of an inner cavity of the frame body, the output end of the motor is connected with a transmission shaft, a shaft body of the transmission shaft is fixedly sleeved with a first L-shaped rod, and the tail end of a vertical rod body of the first L-shaped rod is rotationally connected to the bottom of the fixed plate located on the left side through a first bearing; a vertical shaft and a second L-shaped rod are arranged on the right side of the bottom face of the inner cavity of the frame body; and a plurality of elastic connection pieces are fixed to the side wall of the inner cavity ofthe frame body at equal intervals in the circumferential direction, and the tail ends of the elastic connection pieces are connected with impact blocks. According to the shaking impact type efficientsand screening device, sand is screened in a shaking impact mode, the screening effect can be effectively improved, and meanwhile, sand wasting is avoided.

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.
