Furthermore, stabilizing plates are fixedly connected to two sides of the motor, through holes are formed in the two stabilizing plates, two vertical limiting rods are fixed in the fixing box, and the limiting rods are in sliding connection with the through holes and correspond to the through holes one to one. Its purpose is, through this kind of setting avoid the motor to take place crooked.

Furthermore, both ends of the stirring arm are fixedly connected with vertical stirring rods. The purpose is to increase the stirring efficiency by this arrangement.

Further, the bottom of agitated kettle is equipped with the bin outlet, the intercommunication has the row material pipe in the bin outlet, be equipped with the ooff valve on the row material pipe. The concrete in the mixing pot can be discharged from the discharge pipe by opening the switch valve after the concrete in the mixing pot is uniformly mixed.

Further, the discharge pipe is arranged in a downward inclined mode. The aim is that concrete is not easy to remain in the downward inclined discharge pipe.
