Description

Walk-behind forage harvester and shredder

technical field

The utility model relates to a hand-held forage grass harvesting and cutting machine.

Background technique

The micro harvester is a typical agricultural machinery product with Chinese characteristics. Its research and development originated from the special needs of the hilly areas in southern China and the rural areas in the western mountainous areas. In the 1980s, large and medium-sized harvesters had spread across northern my country and the Central Plains, but farmers in the hilly and mountainous areas of the south could only wait and sigh, and the level of agricultural mechanization in the south was still at a low level. The most direct and main factor for the formation of this phenomenon is the great difference in topography and farming conditions in the southern hilly and mountainous areas. There are many small fields and terraced fields in the south, the per capita arable land area is small, and the traffic conditions between fields are extremely poor, which is not conducive to large-scale machinery operations. With the rapid development of grass-fed animal husbandry in the south, the planting area of forage grass is increasing, and forage grass harvesting and forage processing have become one of the most arduous labors in grass-fed livestock breeding, and are also one of the inputs with the highest cost in producing feed. Realizing the mechanization of forage production as soon as possible has become the dream of professional households in southern grass and livestock breeding.

Most of the existing small harvesters adopt the backpack type, which is still a heavy labor and the work efficiency is not high. Some "floor-type" small harvesters only cut crops but cannot harvest them. When harvesting, they still leave the crops in the field, which requires secondary harvesting, duplication of labor, and increased labor and cost.
