High-efficient and easy-for-discharging sand screening device used at construction site

Abstract

The invention discloses a high-efficient and easy-for-discharging sand screening device used at a construction site. The high-efficient and easy-for-discharging sand screening device comprises a base,a sand screening frame, a screening plate and a sliding rod, wherein the sliding rod is arranged on a right and lower part of the sand screening frame; a bottom of the sliding rod is connected with the base through a telescopic spring; and a resisting plate is fixedly arranged on a left side of the sliding rod and is matched with a rotary resisting wheel. According to the high-efficient and easy-for-discharging sand screening device, through cooperation use of the resisting wheel and the resisting plate, the sliding rod can be driven to impact the sand screening frame continuously during rotation of a rotary rod, so that the sand screening frame which is elastically connected is vibrated so as to screen sand; meanwhile, the sand screening frame is suddenly tilted under impact of the sliding rod, so that the sand on the screening plate is flung about; sand caking is prevented, and sand screening efficiency is improved; after sand screening is finished, the sand screening frame is tilted by pulling a steel rope, so that the sand screening frame is lower on the left and higher on the right; and the sand can automatically slide out of a material outlet pipe under the effect of gravity, and an effect of more convenient discharging is reached.

Description

Technical field [0001] The invention relates to a sand screening device, in particular to a sand screening device for construction sites that is efficient and easy to unload. Background technique [0002] The construction industry is a production department that specializes in civil engineering, housing construction, equipment installation, and engineering survey and design work. Its products are buildings, structures and facilities of various factories, mines, railways, bridges, ports, roads, pipelines, houses and public facilities. [0003] Sand screening devices are often used in the construction process of the construction industry to screen sand and gravel. Most of the existing sand screening devices cannot turn the sand and gravel during the sand screening process, and the sand and gravel are easy to accumulate into blocks, which leads to the efficiency of sand screening. At the same time, the existing sand screening device still has the defect of inconvenient feeding. Summ...
