Technical Field

The invention relates to the field of agricultural machinery, in particular to a harvester.

Background

China is a world large country for agricultural production, and agricultural mechanization is continuously developed in China for further reducing the labor intensity of farmers and improving the production efficiency. In actual operation, crops and operation environments faced by agricultural machinery are increasingly complex and diverse, the mechanization degree of the traditional agricultural machinery in China to the special crops is not high, but the requirement of the special crops on the mechanization is more urgent, such as the oil sand beans.

The sweetened bean paste is also called as the sweetgrass, is originally produced in northeast of Africa, is originally named as 'underground walnut', can be used for extracting oil, is a delicious dish on a dining table, is stewed, fried and fried, is crisp, fragrant, sweet and delicious, and is a difficult delicious food, so that the sweetened bean paste is larger and larger in planting area in China. In actual operation, the elaeagnus mollis is an overground, standing grain and underground result, the underground nuclear rhizome and fruit is mainly picked during harvesting, and existing designed harvesters are usually directed at crops with fruit growing on the overground stem, so that the existing elaeagnus mollis can be picked only manually by manpower, and therefore, the labor intensity of farmers is extremely high, and the harvesting efficiency is extremely low.
