[0038] The first main shaft 12 is rotatably arranged in the accommodating cavity 101 and extends vertically. A first bevel gear 15 and a second bevel gear 16 are fixed on the first main shaft 12. The first bevel gear 15 and the second bevel gear 16 are arranged at intervals along the axial direction of the first main shaft 12 and are both located in the accommodating cavity 101. In this embodiment, both ends of the first main shaft 12 are respectively installed on the two end covers 112 through the first bearings 104.

[0039] The second main shaft 13 is rotatably installed on the hub 11 and extends horizontally. The inner end of the second main shaft 13 extends into the accommodating cavity 101. A third bevel gear 17 is fixed at the inner end of the second main shaft 13. The third bevel gear 17 is located in the accommodating cavity 101 and meshes with the first bevel gear 15. The outer end of the second main shaft 13 has a control part 131, and the control part 131 is exposed on the side surface of the hub 10. In this embodiment, the second main shaft 13 is rotatably installed in the first through hole 102 through the second bearing 105. The outer end of the second main shaft 13 passes through the first through hole 102 and extends outwards. And, a protective cover 114 is fixed to the outside of the hub 11 through the third screw 113, and the protective cover 114 covers the control part 131.

[0040] The multiple third main shafts 14 are all rotatably mounted on the hub 11 and extend horizontally. The multiple third main shafts 14 are arranged at circumferential intervals around the axis of the first main shaft 12. A fourth bevel gear 18 is fixed to the inner end of each third main shaft 14. Each fourth bevel gear 18 meshes with the second bevel gear 16. A short blade 19 is fixed to the outer end of each third main shaft 14. The short blade 19 is located outside the hub 11. A stirring blade 106 is fixed to each short blade 19 and extends outward. In this embodiment, there are three third main shafts 14 arranged at equal angles, not limited thereto. The multiple third main shafts 14 are respectively rotatably mounted in multiple second through holes 103 through third bearings 107, and the outer ends of the multiple third main shafts 14 respectively pass through the multiple second through holes 103 and extend outward.

The rotation of the second main shaft 13 drives the first bevel gear 15 to rotate through the third bevel gear 17. Then, the first bevel gear 15 drives the first main shaft 12 to rotate. Then, the first main shaft 12 drives each fourth bevel gear 18 to rotate through the second bevel gear 16, so that each third main shaft 14 rotates. Then, the short blade 19 and the stirring blade 106 rotate with the third main shaft 14, thereby realizing the adjustment of the angle of the stirring blade 106. After the angle adjustment is completed, install and fix the protective cover 114.
