[0002] Concrete aggregates typically refer to cement concrete, which is made by mixing cement as a binder with sand and stone as aggregates in a certain proportion. It has the characteristics of high compressive strength and good durability, and is one of the important materials in the construction industry. When used with concrete pumping equipment, it can realize long-distance concrete delivery to high-rise buildings or indoors.

Existing concrete pumping systems use wire mesh filters to prevent clumps from forming when adding aggregate to the storage tank. However, after prolonged use, these metal meshes tend to accumulate large amounts of concrete clumps, eventually clogging sections and causing slow feed rates into the pumping unit. Current metal meshes are often installed using wire or other detachable methods. When significant clumps accumulate, they must be cleaned after stopping concrete addition to the storage tank. Furthermore, clumps can become stuck in the mesh, making cleaning difficult and hindering continuous aggregate delivery. Utility Model Content
