[0018] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments; based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0019] like Figure 1 , Figure 2 and Figure 3 As shown, an automatic cleaning device for a concrete mixing station comprises a bracket 1 and a mixing tank 2 installed on the top of the bracket 1, a mixing assembly is arranged inside the mixing tank 2, a motor 3 for driving the mixing assembly to rotate is installed at the bottom, a discharge port is arranged at the lower side, an opening is arranged at the top of the mixing tank 2, and a cover plate 4 is installed at the opening, the mixing assembly comprises a mixing shaft 14, a plurality of positioning rods 15 are installed on the mixing shaft 14, a mixing blade 16 is installed on the positioning rod 15, a scraper 17 is installed at the bottom of the positioning rod 15, a material guide trough 18 is arranged outside the discharge port, and a baffle 19 for sealing the discharge port is installed at the connection between the material guide trough 18 and the mixing tank 2.

[0020] Open the cover plate 4, add concrete raw materials and water into the mixing tank 2, and the motor 3 drives the mixing assembly to rotate, so that the concrete can be mixed evenly.

[0021] A water tank 5 is installed on the top of the stirring tank 2, and a water inlet pipe 6 is connected to the upper part of one side of the water tank 5, and a control panel 20 is installed on the other side. The lower front end is connected to a water pump 7 through a connecting pipe, and a solenoid valve is installed on the water inlet pipe 6. An ultrasonic level meter 21 is installed on the top of the water tank 5. The water outlet end of the water pump 7 is connected to a vertical pipe 9 that penetrates the top surface of the stirring tank 2 through a conduit 8 through a rotating joint. A positioning seat 22 is fixedly connected to the top of the stirring tank 2, and the vertical pipe 9 penetrates and is rotatably connected to the positioning seat 22.
