[0002] Rotary tillers are tillage machines used in conjunction with tractors to perform tilling and harrowing operations. They are widely used due to their strong soil-breaking ability and ability to flatten the soil surface after tilling. They can also chop up root stubble buried below the surface, making it easier for seeders to operate and providing a good seedbed for later sowing. According to the configuration of their rotary tiller shafts, they are divided into three types: horizontal shaft type, vertical shaft type, and inclined type. Correct use and adjustment of rotary tillers are very important for maintaining their good technical condition and ensuring tillage quality.

[0003] When the rotary tiller's blade shaft rotates, it needs to be driven by a gearbox and a motor. Therefore, a gearbox structure for driving the rotary tiller blade shaft is required. Summary of the Invention
