Technical Field

The invention relates to a peanut harvester, and belongs to the field of machinery.

Background

With the circulation of land, the planting area of peanuts is continuously increased, the harvesting of the peanuts is slow and heavy, particularly, when the peanuts reach the maturity and the later period, the peanuts are easy to have broken needles and fall fruits, the labor intensity becomes larger, and the peanuts are difficult to be harvested completely. Therefore, peanut harvesting machines are increasingly used, and among them, small self-propelled peanut combine harvesters have the highest preservation. At present, the traditional machine type mainly depends on a manipulator to realize alignment, the requirement on the operating skill of the manipulator is high, and a plurality of auxiliary personnel are provided during operation; peanut seedlings are easy to tangle on a peanut harvester, so that the harvesting operation of peanuts is influenced, and even the peanut harvester is damaged; soil attached to peanuts cannot be removed completely, so that the one-way carrying capacity is low, and the round-trip cost is increased; the peanuts are often doped with impurities such as weeds and the like, and manual screening is needed in the later period, so that the labor cost is increased; the peanut picking is not thorough, and part of peanuts are discharged with stalks without being picked, so that waste is caused; the harvester feed inlet is easily entangled by skewed stalks, causing blockage of the feed inlet.
