The driving unit 100 drives the stirring unit 400 through the transmission unit 300, with a simple and compact structure and good stability. An oil sealing unit 200 is provided between the driving unit 100 and the transmission unit 300 to prevent lubricating oil from leaking. Specifically, the driving unit 100 is a servo motor, and the stirring unit 400 is a stirring blade, which includes a shaft sleeve and a plurality of blades fixedly connected to the outer wall of the shaft sleeve.

[0034] Specifically, please refer to Figure 2 and Figure 3 , the oil sealing unit 200 includes a bearing cylinder 201 and a propulsion pump handle 202 rotatably installed in the bearing cylinder 201. A first bearing 205 is sleeved on the stepped shaft of the propulsion pump handle 202. A nut 206 for positioning a pair of first bearings 205 is provided on the side of the first bearing 205 close to the driving unit 100 to limit the movement of the first bearing 205 in the direction of the driving unit 100, and an oil seal 203 sleeved on the propulsion pump handle 202 close to the transmission unit 300 to prevent lubricating oil from leaking from the propulsion pump handle 202. A copper sleeve 207 is sleeved on the side of the oil seal 203 away from the transmission unit 300 on the propulsion pump handle 202. The propulsion pump handle 202 runs smoothly in the bearing cylinder 201 by means of the first bearing 205 and the copper sleeve 207.

[0035] Specifically, please refer to Figure 2 and Figure 5 , a flange 204 is sleeved on the bearing cylinder 201. The bearing cylinder 201 is fixed to the oil storage barrel 500 by means of the flange 204, and sealing is achieved by using gaskets and fasteners to prevent external impurities such as dust and dirt from entering the bearing cylinder 201, and also to prevent lubricating oil from leaking.

Specifically, both the driving wheel 301 and the driven wheel 302 are bevel gears, so as to convert the horizontal rotational movement of the propulsion pump handle 202 into the vertical rotational movement of the driven shaft 303. At the same time, since the transmission unit 300 is located in the oil storage barrel 500, the lubricating oil can fill the meshing gaps between the gears and play a lubricating role.

[0037] Please refer to Figure 2, one end of the propulsion pump handle 202 is connected to the output shaft of the servo motor, and the other end is connected to the driving wheel 301 through a flat key. The driving wheel 301 meshes with the driven wheel 302, and the driven wheel 302 is connected to the driven shaft 303. One end of the driven shaft 303 relative to the driven wheel 302 is connected to the stirring paddle. Thus, during operation, the servo motor can drive the propulsion pump handle 202 to rotate, the propulsion pump handle 202 drives the driving wheel 301 to rotate, the driving wheel 301 drives the driven wheel 302 to rotate, the driven wheel 302 drives the driven shaft 303 to rotate, and the driven shaft 303 drives the stirring paddle to rotate, and the stirring paddle stirs the lubricating oil to ensure uniform flow of the lubricating oil.

[0038] Please refer to Figure 5 , the driven shaft 303 is rotatably mounted on a fixing bracket 305 through a second bearing 304, and the fixing bracket 305 is fixed on the inner wall of the oil storage barrel 500 to provide support for the driven shaft 303.

[0039] Please refer to Figure 1 , four snap ring grooves (not shown in the figure) for the snap rings 306 to be embedded are provided on the driven shaft 303, two of which are used to limit the stirring unit 400, one is used to limit the second bearing 304, and one is used to limit the transmission unit 300.

[0040] In summary, through the above structural design, the present utility model solves the deficiencies in the prior art and has the characteristics of simple and compact structure and good stability.
