A detachable top cover 13 is fixedly installed on the top of the reaction tank 1. The inside of the reaction tank 1 can be cleaned by opening the top cover 13.
[0023] Reference Figure 2 and Figure 3The stirring assembly 2 includes a stirring shaft 21 rotatably disposed within the reaction vessel 1 and several stirring rods 22 fixedly connected to the surface of the stirring shaft 21. The drive assembly 3 includes a cylinder 31 fixedly mounted on the top of the reaction vessel 1. A motor 32 is fixedly mounted on the top of the cylinder 31. A sleeve 33 is fixedly connected to the output end of the motor 32. The sleeve 33 is slidably fitted onto the upper end of the stirring shaft 21. A gear ring 34 is fixedly mounted on the surface of the sleeve 33. A gear 35 is meshed with one side of the gear ring 34. A reciprocating screw 36 is fixedly connected to the shaft of the gear 35. The reciprocating screw 36 is rotatably mounted inside the cylinder 31. A ball nut 37 is helically connected to the surface of the reciprocating screw 36. The ball nut 37 is fixedly connected to one end of a support plate 38. The stirring assembly 38 is rotatably mounted on the stirring shaft 21. Through the arrangement of the stirring assembly 2 and the drive assembly 3, during the reaction of the polyurea material, the motor 32 can be started to drive the sleeve 33 to rotate, which in turn drives the stirring shaft 21 to rotate. The stirring shaft 21 then drives the stirring rod 22 to stir the material. At the same time, the sleeve 33 drives the gear ring 34 to rotate, which in turn drives the gear 35 to rotate. The gear 35 then drives the reciprocating screw 36 to rotate, which in turn drives the ball nut 37 to slide back and forth along the reciprocating screw 36. The ball nut 37 then drives the support plate 38 to move up and down, which in turn drives the stirring shaft 21 to move up and down. This allows for continuous adjustment of the height of the stirring rod 22, ensuring uniform stirring and improving the reaction efficiency of the polyurea material.
[0024] The inner wall of the sleeve 33 is provided with a guide groove 39, and the surface of the upper end of the stirring shaft 21 is provided with a guide strip 23 that slides with the guide groove 39.

[0025] Among them, the end of the support plate 38 away from the ball nut 37 is fixedly connected to the guide sleeve 310. The guide sleeve 310 is slidably sleeved on the guide rod 311. The guide rod 311 is fixedly installed inside the cylinder 31. Through the cooperation of the guide sleeve 310 and the guide rod 311, the support plate 38 can be guided, thereby improving the stability of the support plate 38.
[0026] The support plate 38 is fixedly connected to the center of the bearing 312, and the stirring shaft 21 is fixedly inserted through the inner ring of the bearing 312. The bearing 312 enables the support plate 38 to drive the stirring shaft 21 to rise and fall.
[0027] The working principle and usage process of this utility model are as follows: First, during the reaction of polyurea material, the motor 32 can be started to drive the sleeve 33 to rotate, which in turn drives the stirring shaft 21 to rotate. The stirring shaft 21 then drives the stirring rod 22 to stir the material. At the same time, the sleeve 33 drives the gear ring 34 to rotate, which in turn drives the gear 35 to rotate. The gear 35 then drives the reciprocating screw 36 to rotate, which in turn drives the ball nut 37 to slide back and forth along the reciprocating screw 36. The ball nut 37 then drives the support plate 38 to move up and down, which in turn drives the stirring shaft 21 to move up and down. This allows for continuous adjustment of the height of the stirring rod 22, ensuring uniform stirring and improving the reaction efficiency of the polyurea material.
