[0002] Construction refers to the production activities during the implementation phase of construction projects. It is the process of constructing various types of buildings. It can also be said to be the process of turning various lines on design drawings into physical objects at designated locations. It includes foundation construction, main structure construction, roof construction, and decorative construction. The place where construction work takes place is called a "construction site" or "construction site," also known as a construction site. In construction, sand and gravel are one of the indispensable raw materials, and sand and gravel concrete is often used. Currently, there is no screening for the processing of sand and gravel. Sand and gravel are simply mixed and stirred, and cannot be mixed according to a uniform standard of sand and gravel size, which is extremely inconvenient for subsequent use. In existing sand and gravel mixing devices, after mixing, the sand and gravel easily adhere to the inner wall of the mixing device. If not cleaned in time, the sand and gravel will harden on the inner wall of the mixing device, making it difficult to clean and affecting the use effect of the mixing device. In addition, the single stirring blade makes the mixing and dispersion of sand and gravel unsatisfactory and not conducive to uniform mixing. For this reason, we have proposed a sand and gravel mixing device for construction. Utility Model Content
