[0030] Working principle: The material enters the first conveying pipe 101 through the first right-angle feed pipe 102. Driven by the first stirring shaft 106, the first winch blades 107 initially stir the material at the inlet. Subsequently, the material is uniformly mixed under the spiral arrangement of the first mixing blades 108 and conveyed to the first right-angle discharge pipe 103.

This design effectively solves the material agglomeration problem and improves the mixing efficiency of the sand mixer. Two synchronous gears 601 are respectively fixedly connected to two drive shafts close to each other on one side. At one end of shaft 501, synchronous rotation is achieved through gear meshing. A protective cover 602 is fixedly connected to the second support plate 403 to protect the synchronous gear 601 and the drive motor 603. The output end of the drive motor 603 passes through the protective cover 602 and is connected to one of the synchronous gears 601 to drive its rotation. This design simplifies the transmission structure, improves transmission efficiency, and ensures the stable operation of the material agglomeration crushing component 5. Through the transmission of the synchronous gear 601, the synchronous rotation of the two transmission shafts 501 is achieved, ensuring the balanced operation of the material agglomeration crushing component 5. The design of the protective cover 602 prevents interference from debris and safety hazards during gear transmission.
