The stirring shaft 21 is fixedly connected with a high-speed driven gear 47. The high-speed driving gear 46 meshes with the high-speed driven gear 47. The gear ratio of the high-speed driving gear 46 to the high-speed driven gear 47 is greater than the gear ratio of the low-speed driving gear 42 to the low-speed driven gear 43. The connecting sleeve 45 is rotatably connected with a connecting plate 51. The connecting plate 51 is axially clamped with the connecting sleeve 45. A cylinder 52 is provided between the connecting plate 51 and the transmission box 31. The two ends of the cylinder 52 are rotatably connected to the connecting plate 51 and the transmission box 31 respectively. The transmission box 31 is fixedly connected with a guide rod 53. The guide rod 53 is parallel to the connecting sleeve 45 and is penetrated by the connecting plate 51. The driving member 44 is a motor, which realizes the function of the driving member 44 driving the driving shaft 41 to rotate.

[0038] The stirring shaft 21 is fixedly connected to a connecting rod 22, and the connecting rod 22 is fixedly connected to a stirring sleeve 23 sleeved on the stirring shaft 21. The stirring sleeve 23 is located in the stirring tank 11, and the outer wall of the stirring sleeve 23 is fixedly connected to an arc plate 24, a stirring roller 25 and a stirring paddle 26. The arc plate 24, the stirring roller 25 and the stirring paddle 26 are arranged in sequence along the length direction of the stirring sleeve 23. The arc plate 24 is arc-shaped as a whole, and the stirring paddle 26 is tilted.

[0041] This embodiment has the following advantages:

[0042] Since the stirring paddle 26 is tilted, the stirring paddle 26 can push the material at the stirring paddle 26 to move toward the stirring roller 25 and the arc plate 24 during the rotation process, thereby driving the material to flow along the axial direction of the stirring sleeve 23 in the stirring tank 11. The arc plate 24 can push the material to flow along the arc profile of the arc plate 24 toward the inner wall of the stirring tank 11 during the rotation process, thereby driving the material to flow along the circumferential direction of the stirring sleeve 23 in the stirring tank 11. The stirring paddle 26 and the arc plate 24 drive the material to flow in different directions respectively, so that the materials at different positions can flow and pass through the arc plate 24, the stirring roller 25 and the stirring paddle 26, so that the materials at different positions can be fully mixed and stirred, achieving the advantage of better stirring effect.

[0043] The stirring shaft 21 is supported by the transmission box 31 and the connecting seat 32, so that the stirring shaft 21 remains stable during the rotation process, thereby improving the structural stability between the stirring shaft 21 and the stirring tank 11. The driving mechanism drives the stirring shaft 21 to rotate on the transmission box 31, realizing the function of driving the stirring shaft 21 to rotate through the driving device.

[0044] The driving member 44 drives the driving shaft 41 to rotate, and the driving shaft 41 drives the stirring shaft 21 to rotate through the low-speed driving gear 42 and the low-speed driven gear 43, thereby realizing the function of driving the stirring shaft 21 to rotate through the driving mechanism.

[0045] When the stirring speed needs to be increased, the connecting sleeve 45 is slid on the driving shaft 41 to release the meshing state between the low-speed driving gear 42 and the low-speed driven gear 43, and to engage the high-speed driving gear 46 with the high-speed driven gear 47, so that the driving shaft 41 drives the stirring shaft 21 to rotate through the high-speed driving gear 46 and the high-speed driven gear 47 with a larger gear ratio, thereby increasing the rotation speed of the stirring shaft 21.

[0046] The connecting plate 51 is driven to move by the cylinder 52 , and the connecting plate 51 drives the connecting sleeve 45 , the high-speed driving gear 46 , and the low-speed driving gear 42 to move, thereby realizing the function of switching the meshing state of the high-speed driving gear 46 and the low-speed driving gear 42 .

[0047] The connecting plate 51 is guided to move by the guide rod 53 , thereby improving the stability of the connecting plate 51 during the movement, so that the connecting plate 51 can stably drive the connecting sleeve 45 to move.

[0048] The gap between the connecting seat 32 and the stirring shaft 21 is blocked by the sealing ring 33 to prevent liquid from leaking into the transmission box 31, thereby improving the sealing performance.

[0049] Water is injected into the water inlet hole 34. The water in the water inlet hole 34 enters the stirring sleeve 23 through the water inlet pipe 35 and is sprayed into the stirring tank 11 through the water spray hole 36, so as to realize the function of injecting water into the stirring tank 11, and facilitate the uniform injection of water into the stirring tank 11 during the mixing and stirring of materials, thus facilitating the function of injecting water during the stirring process. In the process of cleaning the inside of the stirring tank 11, while spraying water into the stirring tank 11 through the water spray hole 36, the high-speed driving gear 46 and the high-speed driven gear 47 are used to drive the stirring shaft 21 to rotate at a faster speed, and the stirring shaft 21 drives the stirring sleeve 23 to throw water out of the water spray hole 36 at a faster speed, so that the water can be flushed to the inner wall of the stirring tank 11 at a faster speed, and then the inner wall of the stirring tank 11 can be better cleaned, so as to achieve the effect of convenient cleaning of the stirring tank 11.
