Whole-feed combine harvester with double-cutting vertical header and harvesting method thereof

Abstract

The invention discloses a whole-feed combine harvester with a double-cutting vertical header, in which the technologies of double cutting, vertical header and whole feeding are combined to form a new grain harvesting method. When the whole-feed combine harvester with the double-cutting vertical header operates, the vertical header cut the grain into a root part, a straw part and a spike part through two groups of cutters, the straw part cut down is discharged from the outer side of the harvester by a seizing device at the lower row; and the spike part is directly sent into a seed husking plant by a seizing device at the upper row and then is delivered to a cleaning device and an impurity remover for treatments. Compared with the prior art, the whole-feed combine harvester has the advantages of low power consumption, low loss and small volume and is economic and practical. The whole-feed combine harvester is suitable for use in southern areas of China.

Description

technical field [0001] The invention belongs to grain harvesting machinery, in particular to a double-cut vertical header full-feed combine harvester and a harvesting method thereof. Background technique [0002] At present, the combine harvesters on the market are mainly divided into two types: half-feeding type and full-feeding type. Both full-feeding and half-feeding have their own advantages. The feeding combine harvester adopts the mode of reel and cutter to realize the cutting of stalk plants. Due to their different structures, it is directly related to the operation effect ratio. [0003] For the double-cutting vertical header of the combine harvester in the market, typical is a kind of double-cutting combine harvester header disclosed in the invention patent application that the application number submitted on October 31, 1996 is 96242283.5. Although the header of the double-cut combine harvester realizes that only the ear enters the threshing drum, it is a horizont...

AI Technical Summary

Problems solved by technology

However, the fringe needs to be turned over during operation, which will increase the loss rate in the process, and the transmission mechanism for conveying the stalks is complicated, the manufacturing cost is high, and the price is expensive

The price of a half-feed combine harvester is generally 150,000 to 200,000 yuan. According to the statistics of relevant departments, when the investment is 150,000 to 200,000 yuan, the payback period of the capital needs to be 6 to 8 years. When the investment exceeds 200,000 yuan, the investment recovery period As long as 8 to 15 years, plus high spare parts and maintenance costs, although the government subsidy reaches 20% to 50%, farmers still need to spend a lot of money. For most farmers, this can only be hoped. sigh
