[0009] Compared with the prior art, the beneficial effects achieved by the utility model are:

[0010] (1) By providing a gear structure, the rotation of bevel gear 1 drives the meshing bevel gear 2 on one side to rotate. A rotating shaft 2 is fixed inside bevel gear 2. Rotating shaft 2 rotates inside the housing, and gear 1 fixed on its surface is driven to rotate. Gear 2 fixed on the surface of rotating shaft 3 meshes with gear 1 and rotates with gear 1.

The gear box adopts single input and dual output, which means that one motor drives the output shafts in two directions to operate. It has the same power but higher efficiency. It also uses a three-stage transmission, which can meet the transmission ratio required for mining while increasing the shell strength and enhancing the load-bearing capacity.

[0011] (2) A lubrication system is provided, and the sealing groove is used to store oil. The lubricating oil passes through the entire box through the oil pipe. The gear meshing point corresponds to the oil outlet groove. The lubricating oil flows out of the oil outlet groove. As the gears rotate continuously, the lubricating oil is evenly applied to every part, ensuring that the gearbox is sufficiently lubricated during operation, thereby improving work efficiency.

[0018] Specifically, the motor drives the rotating shaft 1 7 to rotate, and the rotation of the bevel gear 1 8 drives the meshing bevel gear 2 9 on one side to rotate. The bevel gear 2 9 is fixed with a rotating shaft 2 14 inside. The rotating shaft 2 14 rotates inside the box body 1, and the gear 10 fixed on its surface is driven to rotate. The gear 2 11 fixed on the surface of the rotating shaft 3 15 meshes with the gear 10 and rotates with the gear 10. The gear 2 11 then drives the meshing gear 3 12 on one side to rotate, so that the output shaft 2 fixed inside the gear 3 12 follows the rotation. The output shaft 2 is used to fix the cutting head on the surface. The gear box adopts single input and dual output, which means that one motor drives the output shafts in two directions to operate. It has the same power but higher efficiency, and uses a three-stage transmission.
