Description

Technical Field

[0001] The utility model relates to the technical field of material screening, in particular to material screening equipment for construction engineering. Background Art

[0002] Construction refers to production activities during the implementation phase of construction projects. It is the process of building various types of buildings. It can also be said to be the process of turning various lines on the design drawings into physical objects at designated locations. It includes foundation engineering construction, main structure construction, roofing engineering construction, decoration engineering construction, etc. The place where the construction work takes place is called the "construction site", also known as the construction site. During the construction process, a variety of materials need to be mixed. During the mixing of concrete, sand and gravel usually need to be screened before they can be used to prevent the gravel particles from being too large and affecting the quality of concrete. However, the screening of construction waste in the existing technology usually adopts manual screening. Workers are in close contact with the screening environment and are prone to respiratory diseases due to excessive adsorption of waste dust. In addition, manual screening of materials is inefficient. For this reason, we propose a material screening device for construction projects. Utility Model Content
