Gravel screening equipment for building construction

Abstract

The gravel screening equipment for building construction comprises a screening box, a screening assembly, a cleaning assembly and a screened residue treatment mechanism, the cleaning assembly is arranged at the top of the upper end of the screening box, a motor set is arranged at the bottom end of the interior of the screening box, and the screening assembly is arranged at the top of the upper end of the motor set; and a screened residue treatment mechanism is arranged at the top of the upper end of the screening assembly, and the screening assembly comprises a main screening plate, a side screening plate, a plastic layer, a discharging groove, a hydraulic rod and an auxiliary supporting frame. According to the gravel screening equipment for building construction, the filter plate serves as a main body structure for gravel screening, gravel at the upper end of the filter plate is in a movable state under the two external force modes of lifting transmission and rotating operation, gravel screening operation can be conveniently completed by penetrating through the filter plate, the gravel is washed in the screening process, and the gravel screening efficiency is improved. Therefore, the cement can be mixed with cement in the subsequent building construction, so that the adhesiveness of the cement in the building process is improved.

Description

technical field [0001] The invention relates to the technical field of building construction, in particular to sand and gravel screening equipment for building construction. Background technique [0002] Due to its good hardness and stable chemical properties, sand and gravel are often used as high-quality building materials and concrete raw materials and are widely used in housing, roads, highways, railways, engineering and other fields. With the requirements of infrastructure construction technology and the development of high technology, there are higher requirements for the quantity and quality of sand and gravel. Sand and gravel are loose materials, but their particles are generally hard and chemically stable in the surface environment. For sandstone, its weathering resistance is generally strong, especially the silicified quartz sandstone, whose hardness exceeds that of granite. Sand and gravel are the basic materials in national economic construction, mainly used in...

Problems solved by technology

[0005] The object of the present invention is to provide a kind of sand and gravel screening equipment for building construction, to solve the existing sand and gravel screening proposed in the above-mentioned background technology generally adopt a screen to support on the ground, people use shovel to screen, Most of the sand and gravel screening equipment used requires a large number of workers to carry out auxiliary operations on site. This kind of sand and gravel screening method is labor-intensive for workers. After a period of screening, workers feel tired and their arms are sore. The problem of large size and low degree of automation will eventually lead to low efficiency of screening work, affecting the construction period of the project, and the sticky soil on the surface of the sand and gravel cannot be screened out, which will affect the subsequent construction and cause stickiness of the sand and gravel. not strong problem
