When stored, individual bags take up more space and are easily affected by moisture and affect use. When stored in large tanks, the top threaded cover is also large, and it is difficult to install and disassemble. After urea is stored for a long time, the accumulation of urea particles on the top presses the urea particles on the bottom, resulting in the bottom urea particles being unable to be naturally discharged from the bottom discharge port.

[0004] Therefore, a urea storage tank is proposed to solve the above problems. Utility Model Content

[0015] 1. When the utility model is used, the device is connected to an external power source, and then the external control terminal is operated, the motor 1 rotates in the opposite direction to drive the threaded cover 1 to rotate in the opposite direction. At the same time, the three-axis cylinder works, the partition slowly rises upward, the threaded cover 1 is separated from the top opening of the storage tank, and then urea particles are added to the inside of the storage tank through the top opening of the storage tank. Then, the external control terminal is operated, the motor 1 works to drive the threaded cover 1 to rotate, the three-axis cylinder works to push the partition downward, and the inner rod moves downward at this time. When the bottom of the threaded cover 1 contacts the top opening of the storage tank, the motor 1 works to drive the threaded cover 1 to rotate, so that the bottom spiral of the threaded cover 1 is embedded in the inside of the top opening of the storage tank.
