[0002] Shaking screens are screening equipment widely used in industries such as mining, building materials, chemicals, pharmaceuticals, and food. In many industrial production processes, it is necessary to accurately classify granular and powdery materials to meet the requirements of different production stages. Automatic shaking screens are required when screening concrete samples.

[0003] Existing automatic shaking screen machines are inconvenient for removing metal filings from concrete samples. Due to the complexity of the concrete preparation process, metal filings may be mixed in at each stage, from aggregate collection and transportation to mixing. These filings vary in size, ranging from small fragments a few millimeters to large flakes several centimeters in diameter. The residue of metal filings can affect the accuracy of concrete sample quality assessment and reduce overall testing efficiency. Utility Model Content

[0004] The purpose of this invention is to provide an automatic sieve shaker with magnetic attraction to solve the problem that existing automatic sieve shakers are inconvenient for removing metal filings from concrete samples.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: an automatic sieve shaker with magnetic attraction, including a sieve shaker body;
