Those skilled in the art should know that the embodiments described below are part of the embodiments of the present disclosure, rather than all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the utility model.

[0020] like Figure 1-Figure 3 As shown, the technical solution adopted by the utility model is as follows: a stirring rod for a mixing mixer comprises a box body 1, wherein two cavities are arranged in the upper and lower parts of the box body 1, the upper cavity is called the first cavity, and the lower cavity is called the second cavity.

[0021] A connecting shaft 5 is rotatably arranged in the first cavity along the vertical direction, and the top of the connecting shaft 5 is rotatably connected to the top of the box body 1. The bottom of the connecting shaft 5 passes through the second cavity, the bottom of the box body 1 and extends to the outside of the box body 1.

[0022] The second bevel gear 4 and the third bevel gear 6 are fixedly sleeved on the circumferential surface of the connecting shaft 5 , and the fifth bevel gear 9 is rotatably sleeved on the circumferential surface of the connecting shaft 5 .

[0023] The second bevel gear 4 is located in the first cavity. The motor 2 is fixedly arranged in the first cavity along the horizontal direction. The first bevel gear 3 is fixedly sleeved on the output shaft of the motor 2. The first bevel gear 3 is meshed with the second bevel gear 4.

[0024] By starting the motor 2, the output shaft of the motor 2 will drive the first bevel gear 3 to rotate, thereby driving the second bevel gear 4 and the connecting shaft 5 to rotate.

[0035] The second motor 2 is started, and the output shaft of the second motor 2 drives the first bevel gear 3 to rotate. The first bevel gear 3 drives the second bevel gear 4 to rotate, thereby driving the connecting shaft 5 to rotate.

[0036] The connection shaft 5 rotates to drive the third bevel gear 6 and the inner stirring blade 11 to rotate.

[0037] The rotation of the connecting shaft 5 will also drive the fourth bevel gear 8 to rotate, and the rotation of the fourth bevel gear 8 will drive the fifth bevel gear 9 to rotate. In addition, the direction of rotation of the fifth bevel gear 9 is opposite to the direction of rotation of the connecting shaft 5.

[0038] The fifth bevel gear 9 rotates to drive the sleeve 12 to rotate, the sleeve 12 rotates to drive the disc 13 to rotate, and the disc 13 rotates to drive the outer stirring blade 14 to rotate.

[0039] During the rotation of the disk 13 , the T-block 17 will slide in the T-slot 18 , so that the rotation of the disk 13 is more stable.

[0040] The different directions of the inner stirring blade 11 and the outer stirring blade 14 can improve the uniformity of stirring.
