Description

Plough harrow agricultural implement depth-adjusting connecting device of mini-tiller

Technical Field

The invention relates to the technical field of mini-tillers, in particular to a depth-adjusting connecting device for a plow harrow farm tool of a mini-tillers.

Background

The large-area mountainous farmland in China has the defects that the large-area mountainous farmland has more fields, narrow ridges and small roads, and large and medium-sized tillers cannot play a role. The mini-tiller is a device developed for solving the problem of farmland farming in mountainous areas. The existing commonly used mini-tiller uses a small diesel engine or a gasoline engine as power, and is widely applied to dry lands, paddy fields, orchards and the like in plains, mountainous areas and hills. Compared with a diesel mini-tiller and a gasoline mini-tiller, the electric mini-tiller using electric power as power uses cleaner and more environment-friendly energy sources, and is more favorable for sustainable development.

The micro-cultivator is more beneficial to cultivation in mountainous areas due to miniaturization. In pursuit of miniaturization, many micro-tillers have reduced many functions, such as a rotary tillage depth adjustment function, compared to other tillers. However, the lack of these functions inevitably causes the inconvenience of using and operating these mini-tillers. If the existing mini-tiller has no function of adjusting the rotary tillage depth, the depth of the resistance tillage cutter inserted into the soil is the same no matter what type of land is tilled by the mini-tiller. Because different soils are not as hard, they are subjected to substantially different resistances for the same depth of tillage. When the mini-tiller is used, the resistance of the mini-tiller is small when some lands are cultivated, the speed is too high, the operation is easy to lose control, and further, certain damage is possibly caused to people; when some lands are cultivated, the speed of the mini-tiller is too low due to large resistance, even the mini-tiller is difficult to move in small steps, so that the abrasion of a transmission mechanism of the mini-tiller is large, and not only is time wasted, but also energy is wasted. In this case, the purpose of adjusting the tilling depth is achieved only by replacing the resistance tilling blades with different lengths, but the resistance tilling blades with different lengths need to be prepared, and the tilling blade needs to be replaced once every time the tilling depth needs to be adjusted, so that the operation is troublesome and the use is inconvenient.
