Description

Technical Field

[0001] This invention relates to the field of agricultural machinery technology, specifically to a hydraulic folding ditching and rotary tillage integrated machine. Background Technology

[0002] Rotary tillers use the power output from a tractor to drive the cutter shaft to rotate. The blades cut into the soil tangentially, breaking up soil clods and throwing them backward, while simultaneously covering the surface with weeds or stubble, thus achieving integrated tillage, soil breaking, and leveling.

[0003] When a rotary tiller is working, it tills and loosens the soil through a rotary tillage mechanism (shovel or plow). However, the current rotary tillage mechanisms have the following main problems: (1) They only have a rotary tillage function and cannot open ditches or ridges as needed, so their function is limited; (2) The parts are difficult to fold, resulting in a large area occupied when not in use; (3) The soil is intact before rotary tillage, and the soil structure is not broken beforehand, which increases the difficulty of rotary tillage. Summary of the Invention
