The upper part of the feed port is connected with the inside of the filter screen, the lower end of the mixing tank is fixedly provided with a bottom turntable, the cantilever support beam is fitted with the unloading system, the transmission shaft is fixedly connected with a spiral blade, and the A transmission motor is arranged at the bottom of the feeding barrel, a turntable motor is fixedly connected to the bottom of the bottom turntable, and legs are fixed on the left and right sides of the bottom turntable, and the push plate communicates with the inside of the discharge port.

Preferably, a water adding system is provided inside the mixing bucket.

Preferably, a transmission wheel is connected to the top end of the transmission shaft.

Preferably, a channel steel is arranged between the feed inlet and the mixing barrel.

Preferably, a flexible joint is installed between the push plate and the discharge port.

Compared with the prior art, the beneficial effect of the utility model is: the concrete mixer is equipped with an automatic conveyor belt, which can effectively save cost and manpower by feeding materials through the screw conveyor, and the mixer is equipped with a frequency conversion motor, which can control the stirring speed. The water adding system eliminates the trouble of manually adding water. There are outriggers at the bottom, which is convenient to move and carry, with a high degree of automation and good mixing effect, which effectively improves the speed of concrete mixing.
