The present invention relates to the technical field of
building construction attachments, in particular to a concrete mixing device, which can improve the
mixing effect of concrete, thereby improving the mixing efficiency; and can prevent
cement and sand and gravel from causing damage to the mixing blade; The
water volume is controlled to improve the use effect of the concrete mixture; it includes a
mixing tank, a base, a water tank and a water pump. The bottom of the
mixing tank is provided with a pillar, 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. There is a
discharge pipe at the bottom of the left end of the mixing tank, and a baffle is provided at the
discharge pipe, a motor is provided at the top of the base, a transmission shaft is provided at the top output end of the motor, and a horizontal stirring blade and a spiral stirring blade are arranged on the transmission shaft. , vertical stirring blades are arranged between the horizontal stirring blades, and four sets of connecting rods, connecting plates, four sets of deflectors, connecting pipes, flow meters, solenoid valves and controllers are also included.
