Efficient peanut combine harvester

Abstract

The invention belongs to the field of needle selectors and discloses an efficient peanut combine harvester which comprises a harvesting mechanism mainframe, a round-pipe grain lifter, a soil shaking mechanism, a pair roller differential phase fruit picking roller arranged on the harvesting mechanism mainframe, a ploughing blade arranged on the lower side of the front end of the harvesting mechanism mainframe, a seedling separator arranged on the lower side of the front end of a rack, a cleaning device arranged on the lower side of the rear end of the rack, a fruit collection box arranged abovethe cleaning device, a lifter arranged on the upper side of the cleaning device, a chassis arranged at the lower end of the rack and a traveling mechanism arranged at the lower end of the chassis ofthe rack. The efficient peanut combine harvester is simple in structure and can effectively avoid the problems of low yield and low peanut harvesting rate in the prior art.

Description

technical field [0001] The invention relates to the technical field of harvesters, in particular to a high-efficiency peanut combine harvester. Background technique [0002] There are many types of 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 agricultural needs. However, most of the peanut harvesters in the prior art use a shovel-like structure to excavate the soil, and use a triangular digging shovel to scoop up the peanuts together with the soil. Most of the collection devices adopt the nail-toothed roller and concave plate structure. The peanut seedlings and fruits pass through the nail-toothed roller, and the peanut seedlings are moved by the nail ruler. The concave plate and the peanut seedlings are frictionally decelerated. The concave screen holes l...

Problems solved by technology

However, most of the peanut harvesters in the prior art use a shovel-like structure to excavate the soil, and use a triangular digging shovel to scoop up the peanuts together with the soil. Most of the collection devices adopt the nail-toothed roller and concave plate structure. The peanut seedlings and fruits pass through the nail-toothed roller, and the peanut seedlings are moved by the nail ruler. The concave plate and the peanut seedlings are frictionally decelerated. Concave plate sieve leaks down and falls into storage unit

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 ridges, resulting in some peanuts not being scooped up, and a small part of peanuts being left behind, which greatly reduces the yield

Moreover, the nail-tooth drum type separation device also has shortcomings. In actual use, due to the existence of soil, the friction between the peanut seedlings and the concave plate will be weakened, so that the nail teeth are difficult to peel off the fruit. The separation rate is not very high. Discarded along with the peanut seedlings, resulting in waste
