Description
Technical Field
[0001] The utility model relates to the technical field of agricultural equipment, in particular to a farmland management machine. Background Art
[0002] A farm tiller is a small agricultural machinery typically used in greenhouses, orchards, and ordinary farmland. It is specifically designed for working in orchards, vegetable fields, greenhouses, hilly slopes, and small plots of land (both irrigated and dry). A farm tiller has a working section, consisting of a tool unit and a travel unit. The travel unit drives the machine, while the tool unit performs the work.
[0003] Existing farmland management machines basically all have an output main shaft, which drives the tool part and the travel part to rotate synchronously. When simply moving the farmland management machine, only the travel part needs to rotate. When focusing on processing a certain area of land, the travel part needs to stop and the tool part rotates. Moreover, when processing the land, the speeds required for the tool and the travel are different, and the speeds of the tool and the travel need to be adjusted according to the actual situation. However, the existing gearbox cannot separate the tool and the travel. In addition, the output main shaft of the existing farmland management machine transmits power to the working part through a chain. The efficiency of the chain transmission is slightly low, and the energy loss is relatively high. During long-term use, the chain may break and separate from the working part or the output main shaft due to wear and fatigue, affecting the normal operation of the machine.
[0004] Therefore, it is urgent to design a farmland management machine that can control the tool and travel separately, and has high transmission efficiency, compact structure, small required volume, simple gearbox structure and simple control. Utility Model Content
