The inside of the second rotating shaft 3 is rotatably connected with a third rotating shaft 8, one end of the third rotating shaft 8 is rotatably connected to the inner wall of the mixing tank 4, and the other end passes through the interior of the fixed frame 1 and extends to the outside of the fixed frame 1, and a plurality of stirring blades 12 are equidistantly and symmetrically fixedly connected to the outside of the third rotating shaft 8 and located inside the mixing tank 4, and a transmission component connected to the driving component is provided on the outer side of the fixed frame 1 and close to the second rotating shaft 3. The transmission component is used to drive the third rotating shaft 8 rotates in a direction opposite to the rotation direction of the first rotating shaft 2. Specifically, when the driving component drives the first rotating shaft 2 to rotate, the mixing tank 4 can be rotated, and the materials inside can be mixed by the rotating mixing tank 4. After the driving component is connected to the transmission component, the third rotating shaft 8 can be rotated under the action of power transmission. When the third rotating shaft 8 rotates, it rotates in a direction opposite to the rotation direction of the first rotating shaft 2, so that the stirring blades 12 can be better driven to rotate in the mixing tank 4 in the direction opposite to the rotation direction of the first rotating shaft 2. Furthermore, based on the opposite rotation directions of the mixing tank 4 and the stirring blades 12, two relative vortices can be formed in the mixing tank 4 to make the materials mixed more evenly. Moreover, the mixing tank 4 and the stirring blades 12 rotating in opposite directions can increase the stirring force and speed of the materials, thereby saving time and energy costs, which is beneficial to improving the mixing efficiency.

[0023] Reference Figure 1 , Figure 2 and Figure 3 The driving assembly includes a motor 5 fixedly connected to the outside of the fixing frame 1, a connecting shaft 7 which passes through the fixing frame 1 transversely and is rotatably connected to the inside of the fixing frame 1, and two first pulleys 6 which are connected by belt transmission. The two first pulleys 6 are respectively fixedly connected to the outside of the connecting shaft 7 and the end of the first rotating shaft 2.

At the same time, a valve 15 is provided on the outside of the inlet and outlet pipe 14. Specifically, the inlet and outlet pipe 14 can be used for the inlet and outlet operation of the material, and the valve 15 can be used to easily control the opening and closing of the inlet and outlet pipe 14.

[0026] Reference Figure 2 and Figure 3 Two observation windows 13 are symmetrically embedded inside the mixing tank 4. Specifically, the observation windows 13 are convenient for users to observe the operation of the mixing work inside the mixing tank 4.

[0027] The motor 5 is electrically connected to an external control device, and the operation state of the motor 5 can be better controlled by operating the external control device, so as to facilitate the control of the device to perform mixing work.

[0028] Working principle: the materials used for processing and producing fire-fighting pipes are added into the mixing tank 4 through the inlet and outlet pipes 14, and the motor 5 is controlled to drive the connecting shaft 7 to rotate, so as to realize the rotation operation of the first pulley 6, and the first rotating shaft 2 can be rotated by the rotating first pulley 6, so as to realize the stirring and mixing of the internal materials.

[0029] When the connecting shaft 7 is driven by the motor 5 to rotate, the second pulley 9 is driven to rotate. Under the action of the rotating second pulley 9, the fourth rotating shaft 10 can be better driven to rotate. When the rotating fourth rotating shaft 10 drives the third rotating shaft 8 to rotate under the action of the gear 11, the third rotating shaft 8 is rotated in the opposite direction to the mixing tank 4. Therefore, the stirring blade 12 can be rotated by the rotating third rotating shaft 8 to better stir and mix the materials inside the mixing tank 4.

[0030] Based on the opposite direction rotation of the mixing tank 4 and the stirring blades 12, two relative vortices can be formed in the mixing tank 4 to make the materials mixed more evenly, and the mixing tank 4 and the stirring blades 12 rotating in opposite directions can increase the stirring force and speed of the materials, thereby saving time and energy costs and helping to improve mixing efficiency.
