Description

Technical Field

[0001] The utility model relates to the field of concrete production, in particular to a concrete mixer used in a concrete production line. Background Art

[0002] Concrete refers to a general term for engineering composite materials that are made of aggregates bonded together by cementitious materials. In the production process, concrete generally uses cement as the cementitious material, sand and gravel as aggregates, and is mixed with water in a certain proportion. Cement concrete can be made after stirring. When stirring concrete, a concrete mixer used in a concrete production line is required.

[0003] The Chinese patent with the publication number CN220241943U discloses a concrete mixer for a concrete production line. The utility model includes: a base, a mixing barrel, a mounting frame and a motor. The inner side of the base is rotatably connected to the mixing barrel, and the lower end of the mixing barrel is provided with a discharge valve. The mounting frame is welded to the base, and the motor is mounted on the mounting frame. The rotating shaft of the motor is connected to the rotating shaft, and the rotating shaft is provided with a square stirring blade and a second toothed disc. The utility model stirs the inside of the mixing barrel by driving the square stirring blade to rotate through the motor. When the motor rotates, it will drive the mixing barrel to rotate inward, and use the arc stirring blade to stir the inside. The cooperation between the two can improve the stirring effect; the electric cylinder shrinks and drives the round tube to insert downward into the inside of the mixing barrel, and then the motor drives the mixing barrel to rotate and uses the high-pressure nozzle to flush the inner wall of the mixing barrel, which facilitates the cleaning of the inner wall of the mixer.

[0004] During use, the above-mentioned equipment improves the mixing efficiency by the relative rotation of the inner and outer mechanisms. The feeding position is not clear enough, and multiple materials are directly dumped during the feeding process. The initial positions of the materials are set in layers. Simple horizontal rotation and mixing will not mix the materials of the upper and lower layers sufficiently, which in turn affects the quality of the mixed concrete. This needs to be optimized and improved. Utility Model Content
