[0002] As we all know, a concrete mixer is a machine that mixes cement, sand and gravel aggregates and water and mixes them into concrete mixtures. It has been widely used in the fields of building construction, road construction, bridge construction, etc.; the existing The concrete mixer includes a mixing tank, a base, a water tank and a water pump. The bottom of the mixing tank is provided with outriggers, and the bottom of the outriggers is connected to the top of the base. The inside of the mixing tank is provided with a working chamber, and the top of the mixing tank is connected with a feeding hopper. , the bottom of the left end of the mixing tank is provided with a discharge pipe, and a baffle is provided at the discharge pipe, the top of the base is provided with a motor, the top output end of the motor is provided with a transmission shaft, and the top of the transmission shaft extends from the bottom of the mixing tank. Into the working chamber, the transmission shaft is equipped with stirring blades, the stirring blades are located in the working chamber, the water tank and the water pump are located on the top of the base, the input end of the water pump extends from the bottom of the left side wall of the water tank to the inside of the water tank, the output of the water pump The end extends into the working cavity from the top of the right wall of the mixing tank; when the existing concrete mixer is used, the cement and sand and gravel aggregates are introduced into the working cavity from the hopper, and the water in the water tank is introduced into the working cavity through the water pump. In the cavity, the motor drives the stirring blades to rotate to stir the cement, sand and gravel aggregates and water. After the mixing is completed, the concrete mixture can be exported from the discharge pipe by opening the baffle; Due to the relatively high viscosity of concrete, it can mix the concrete near the mixing blade more evenly, but the mixing effect on the concrete far away from the mixing blade is poor, resulting in low reliability in use; and the cement sand is relatively heavy, so it falls directly on the mixing blade. The blade is easy to cause damage to the mixing blade; at the same time, it is impossible to control the amount of water added, which will easily cause the concrete mixture to be too thick or too thin, which will affect the effect of concrete.
