DETAILED DESCRIPTION

[0018] The utility model is further described below in conjunction with the accompanying drawings:

[0019] like Figures 1 to 4A stirring tank shown includes a tank body 10, which is a hollow structure and has an opening on the top to form an open end. A cover body 20 is provided on the open end. The cover body 20 includes a fixed cover 201 and a flip cover 202 symmetrically flipped and connected to both sides of the fixed cover 201. The fixed cover 201 is fixed to the tank body 10. A motor 30 is installed on the fixed cover 201, and the output end of the motor 30 is connected to the rotating shaft 50 through a coupling 40. The output end of the motor 30 is connected to the rotating shaft 50 through the coupling 40.
