Problems solved by technology

[0003] When screening sand, it is usually necessary to use a sand sieving machine for operation. Due to structural limitations, the current sand screening device often relies on a metal mesh placed obliquely, and then the construction personnel shovel the sand into the metal mesh for screening. , because the metal mesh is always in a static state during sieving, the work efficiency is low during sieving, and at the same time, it is necessary to manually repeat the sand shoveling operation, which is time-consuming and laborious

Abstract

The invention relates to the technical field of civil engineering, and discloses a sand and stone automatic and equivalent screening device for civil engineering. The device comprises a base, an inclined plate is fixedly connected to the upper portion of the base, a screening plate is movably connected to the upper portion of the inclined plate, a sand screening mechanism is movably connected to the lower portion of the screening plate, a sand storage chamber is fixedly connected to the upper portion of the base, and a feeding chamber is fixedly connected to the upper portion of the screening plate. Through cooperative use of the feeding chamber, a third rotating disc, a rotating rod, a small gear, a special-shaped wheel and a rotating roller, during sand screening, multiple times of equivalent and automatic screening can be automatically carried out, the situation that the sand screening effect is affected by continuous feeding is avoided, meanwhile, and the situation that the feeding chamber is blocked by continuous feeding is avoided; and through cooperative use of the screening plate, the sand screening mechanism, limiting rods, special-shaped discs, a first rotary disc, a second rotary disc and the sand storage chamber, when sand and stone are screened, screening is automatically carried out through vibration, manual operation is not needed, more time and labor are saved, and the sand and stone screening efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of civil engineering, in particular to a device for automatic and equivalent screening of sand and gravel used in civil engineering. Background technique [0002] Civil engineering is a general term for the science and technology of building various land engineering facilities. In the construction of various engineering facilities, sand is widely used. According to the use requirements of engineering facilities, it is often necessary to use sand with a qualified particle size, so as to meet the construction requirements. However, the directly mined sand is mixed with large grains of sand, and the directly mined sand needs to be screened before it can be used. [0003] When screening sand, it is usually necessary to use a sand sieving machine for operation. Due to structural limitations, the current sand screening device often relies on a metal mesh placed obliquely, and then the construction personnel shovel...
