[0002] Sand and gravel are a commonly used building material in the construction industry. They play an important role in many aspects. As one of the main components of concrete, concrete is usually mixed with cement, sand, aggregate and water. The use of sand helps to improve the fluidity of concrete, while gravel provides strength and stability to concrete.

[0003] When in use, it is usually necessary to filter and separate the sand and gravel. The current filtering method is generally to place a screen at an angle, and then manually put the sand and gravel onto the screen for filtering and separation. In this way, the filtering effect of each time the sand and gravel are put is not thorough, and repeated filtering is required, resulting in low filtering efficiency. For this reason, we propose a sand and gravel filtering device for construction. Utility Model Content
