Technical Field
[0001] This utility model relates to the field of building equipment technology, and in particular to a high-efficiency sand screening machine for building construction. Background Technology
[0002] Construction sand screening machines are used to screen and classify sand in building materials. Different particle sizes of sand are commonly used in construction. Screening allows sand to be classified according to a specific size range to meet specific engineering requirements. For example, concrete requires sand of different particle sizes to achieve design strength and material performance requirements. Sand used in structures should have impurities such as mud, organic matter, and other solid particles removed as much as possible. Screening effectively reduces the impurity content in sand by removing large particles, ensuring the quality and strength of materials during construction.
[0003] However, traditional sand screening machines are mostly inconvenient for breaking up the sand before screening. As a result, the sand clumps formed during long-term transportation can easily clog the screening mesh, further affecting the screening quality of the sand screening machine. At the same time, traditional sand screening machines are mostly inconvenient for workers to collect the screened sand and the impurities and foreign objects in the sand in batches during the screening process. Therefore, technical improvements are urgently needed. Utility Model Content
