Peanut harvester

Abstract

The invention discloses a peanut harvester, and belongs to the technical field of peanut harvesters. The peanut harvester comprises a vehicle head part, a stripping mechanism, a screening and separating mechanism and a collecting mechanism, wherein the vehicle head part is used for pulling peanuts up; the stripping mechanism is connected with the vehicle head and used for stripping the peanuts; the screening and separating mechanism is connected with the stripping mechanism and used for screening the peanuts; the collecting mechanism is connected with the screening and separating mechanism and used for collecting the peanuts. The peanut harvester has the advantages of being high in collection rate, clean in peanut separation and higher in automation degree, and saving more energy.

Description

technical field [0001] The invention relates to the technical field of peanut harvesters. Background technique [0002] There are many existing agricultural harvesters, but those specially used for harvesting peanuts are not common. With the development of agriculture and agricultural machinery in recent years, peanut harvesters suitable for large-scale peanut production and harvesting have gradually become an agricultural demand. However, most of the peanut harvesters that occur today use a shovel-shaped structure to excavate the soil, and use a triangular digging shovel to scoop up the peanuts together with the soil. The nail-toothed roller and concave plate type are adopted. The peanut vines and fruits pass through the nail-toothed roller, and the peanut vines are moved by the nail ruler. The concave plate and the peanut vines are frictionally decelerated. down, down to the storage device. Although the device of digging peanuts with multiple sets of side-by-side triangu...

Problems solved by technology

However, most of the peanut harvesters that occur today use a shovel-shaped structure to excavate the soil, and use a triangular digging shovel to scoop up the peanuts together with the soil. The nail-toothed roller and concave plate type are adopted. The peanut vines and fruits pass through the nail-toothed roller, and the peanut vines are moved by the nail ruler. The concave plate and the peanut vines are frictionally decelerated. down, drop to storage device

Although the device of digging peanuts with multiple sets of side-by-side triangular shovels is very effective, it will consume a lot of energy to shovel up about 10cm of land, and it will also cause some peanuts to be shoveled. Since peanuts are mostly planted in rows, after starting the harvester , it is difficult for the machine to align the peanut ridge, causing some peanuts not to be scooped up, and a small part is left behind

The nail-tooth drum type separation device also has shortcomings. In actual use, due to the existence of soil, the friction between the peanut vine and the concave plate will be weakened, so it is difficult for the nail teeth to peel off the fruit. The separation rate is not very high, and some fruits follow Peanut vines are discarded, creating waste
