Description

Technical Field

[0001] The utility model relates to the technical field of agricultural machinery, in particular to a riding rotary tillage and soil-raising machine. Background Art

[0002] Currently, when cultivating fields, a hilling machine is commonly used. Hilling machines utilize the principle of rotary tillage blades, where a diesel engine drives the blades, which throw soil to the sides. As the hilling machine moves forward, a low center, high side bump forms along the hilling machine's path, achieving furrowing and hilling.

[0003] Taking sugarcane cultivation as an example, wide-row planting is currently being promoted to facilitate mechanical operation. However, small hilling machines have a narrow mounding width, and the soil they throw doesn't adequately cover the sugarcane roots. They also require manual operation, making them labor-intensive. During the second and third mounding of the sugarcane, when the cane has grown considerably taller, large hilling machines are unsuitable for this purpose, requiring the use of a suitable small hilling machine. Existing small hilling machines require walking operation, resulting in high operator labor intensity, low efficiency, and fatigue. To reduce operator workload, researchers have adopted the structure of seated rotary tillers, installing a seat on the rear side of the existing rotary tiller through a sitting beam to create a ride-on rotary tiller and replacing it with a larger hilling blade. Because the engines in existing rotary tillers are relatively underpowered, the operator's seated position shifts the center of gravity toward the rear end of the machine, making it tail-heavy and front-light, resulting in insufficient power and unstable movement. Therefore, some users have opted for higher-powered engines to address this power shortage.

[0004] Application research revealed that while installing a higher-power engine solved the power shortage, the resulting torque was high. Power was input from the power input port, shifted by the auxiliary transmission gear, and transmitted to the secondary shaft. This secondary shaft then split the power into two paths: one to the tilling shaft and the other to the drive shaft for propulsion. Both propulsion and rotary tillage output power passed through the auxiliary transmission gear and the first-gear drive gear. In actual use, this pair of gears was prone to damage and gear shifting. Due to structural limitations, replacing this pair of gears was difficult and required draining the transmission oil, which damaged the joint seals. Furthermore, the difference in the auxiliary transmission's high and low gear ratios meant that high gear was generally only used for transport and transfer, not rotary tillage. The propulsion transmission and coulter drive box were bolted together. If significant resistance on the shaft was encountered during operation, the machine would have to be dismounted and lifted from the rear. This was unsafe and inconvenient for seated tillage, making it unsuitable for the current aging rural population. Therefore, it is necessary to improve the design of a riding rotary tillage hilling machine in which the rotary tillage transmission gear is not easily damaged and the tillage depth of the rotary tillage hilling knife can be adjusted.
