In the production process of concrete, mixing is a vital link, which directly affects the quality and performance of concrete. Concrete refers to a general term for engineering composite materials in which aggregates are bonded into a whole by cementitious materials. In the actual production process, concrete generally uses cement as a cementitious material, sand and gravel as aggregates, and is mixed with water in a certain proportion. After mixing, it can be made into cement concrete, also known as ordinary concrete. The conveyor transports the concrete production raw materials to the mixing barrel, and the rotation of the mixing barrel drives the production raw materials in the mixing barrel to mix, completing the mixing production of concrete.
[0003] Most traditional concrete mixers use motors to drive the stirring blades to stir the materials. Since the raw materials for concrete production contain sand and gravel, which have a high density, the sand and gravel sink to the bottom during the mixing process, resulting in uneven mixing of the raw materials. Therefore, we need to propose a concrete mixer for concrete production. Utility Model Content

Specifically, the output shaft of the first drive motor 702 drives the reciprocating screw rod 701 to rotate, thereby driving the moving block 703 to reciprocate along the axial direction of the reciprocating screw rod 701;
[0025] It also includes four groups of movable rods 9, which are all slidably inserted into the interior of the connecting plate 5, the top ends of the four groups of movable rods 9 are all fixedly connected to the bottom of the moving block 703, and the top of the lifting plate 8 is fixedly connected to the bottom ends of the four groups of movable rods 9;
[0026] Specifically, when the moving block 703 moves, it can drive the movable rod 9 to reciprocate in the vertical direction, thereby causing the stirring assembly 6 to reciprocate in the vertical direction through the lifting plate 8;
