Description

A lawn mowing machine

technical field

The invention relates to the technical field of animal husbandry machinery, in particular to a lawn mowing and shaving machine.

Background technique

There are many types of pastures in my country, and some pastures can be mowed several times a year. The best harvest period is about 10-15 days each time. The time is tight and the tasks are heavy, and there is a phenomenon of rush harvesting. Advanced forage harvesting machinery is an important guarantee for improving forage harvesting efficiency and forage quality. The use of machinery to harvest forage in time not only retains the nutrients and dry matter of the original forage, but also greatly increases labor productivity, reduces forage loss, and increases the economic benefits brought by forage production. The northwestern region is vast and sparsely populated. Although it has abundant grassland resources, accounting for 64.1% of the country's grasslands, the harvest season for forage is mostly the rainy season. Especially for high-quality pasture like alfalfa, the drying speed determines the quality of the pasture. The harvested pasture is naturally dried in the field, which not only causes the pasture to rot and deteriorate after a long drying time, but also is not conducive to the maintenance of the pasture nutrients and dry matter. Therefore, this also puts forward multi-functional requirements for the forage harvester, and it is necessary to speed up the drying speed of the forage. The forage planting environment in my country is harsh, the terrain is undulating, and most of the local forage harvesting equipment is outdated, and the height control of the stubble is unstable. When cutting at a low level, the cutter easily destroys the soil structure of the surface planted forage, and exposes the sandy land, making the originally weak grassland.
