Description

Technical Field

[0001] The utility model relates to the technical field of ploughs, in particular to a plough lifting device for a micro-tillage machine. Background Art

[0002] The micro-tillage machine is powered by a small diesel engine or gasoline engine, and has the characteristics of light weight, small size, simple structure, etc. The micro-tillage machine is widely used in dry land, paddy fields, orchards, etc. in plains, mountainous areas, and hills. It can be equipped with corresponding machines for pumping, power generation, spraying, and spraying. It can also be towed by a trailer for short-distance transportation. The micro-tillage machine can be freely used in the field, which is convenient for users to use and store, eliminating the trouble that large agricultural machinery cannot enter the mountainous fields. It is the best choice for farmers and consumers to replace cattle plowing. The plow is the most basic and important reclamation tool in agricultural production.

[0003] At present, many micro-tillage machines have reduced many functions compared with other tillage machines, such as the function of adjusting the depth of rotary tillage. However, the lack of these functions will inevitably lead to the inconvenience of these micro-tillage machines in operation. For example, the existing micro-tillage machines do not have the function of adjusting the depth of rotary tillage. No matter what type of land the micro-tillage machine cultivates, the depth of its resistance tillage blade inserted into the soil is the same. Because the hardness of different soils is different, the resistance they receive is completely different under the same rotary tillage depth. This makes the micro-tillage machine in use. When cultivating some land, the micro-tillage machine receives small resistance and too fast speed, which can easily lead to loss of control and may cause certain harm to people; when cultivating some land, the micro-tillage machine receives large resistance and too slow speed or even difficult to move, which makes the transmission mechanism of the micro-tillage machine suffer greater wear, which not only wastes time but also wastes energy. In this case, the purpose of adjusting the tillage depth can only be achieved by replacing resistance tillage blades of different lengths, but in this way, resistance tillage blades of different lengths must be prepared, and the tillage blades must be replaced every time the tillage depth needs to be adjusted, which is very troublesome to operate and inconvenient to use. Therefore, a plow lifting device for a micro-tillage machine is invented. Utility Model Content
