Combined harvester header for partitioned harvest of millet stalks and ears and application method thereof

Abstract

The invention provides a combined harvester header for partitioned harvest of millet stalks and ears and an application thereof with the aim of resolving the problem that a conventional millet combined harvester causes waste by harvesting ear heads and stalks together. The combined harvester header comprises a header rack, a lower-layer cutting knife, an upper-layer cutting knife, a grain liftingboard, a conveyor and an adjusting device. The lower-layer cutting knife is arranged on the header rack and close to the one side of the ground. The upper-layer cutting knife is arranged by being close to the position above the header rack. The grain lifting board is arranged between the lower-layer cutting knife and the upper-layer cutting knife and used for pressing against to-be-harvested millets. The conveyor is used for collecting millet ears which are cut off by the upper-layer cutting knife. The adjusting device is arranged between the lower-layer cutting knife and the upper-layer cutting knife and used for adjusting the distance between the lower-layer cutting knife and the upper-layer cutting knife so as to be suitable for different kinds of millet heights. With the combined harvester header for partitioned harvest of millet stalks and ears, power consumption of machinery is reduced, which facilitates threshing and cleaning subsequently. Therefore, waste of millets is reduced.Segments of cut stalks are uniform in lengths, which is good for subsequent processing and feeding of stalk segments. Therefore, feeding value of stalks is increased.

Description

technical field [0001] The invention belongs to the technical field of agricultural machinery. Specifically, the invention relates to a combine harvester header for segmentally harvesting millet stems and ears and a use method thereof. Background technique [0002] At present, the harvesting method of millet is mainly segmented harvesting, which is to harvest millet first, and then carry out threshing and full-feed millet mechanical harvesting. The former is labor-intensive and inefficient, and now it is gradually adopting mechanical harvesting; although the harvesting efficiency of the latter is relatively high, compared with the stalks of wheat and rice, the stalks of millet are longer and thicker, and the ears and stalks are harvested If it is separated in the machine drum, the power consumption of the machine will increase, and if the stalk is too long, it may wind around the drum, so that the removal rate of millet is low and the loss is high; if only the ear head part ...

AI Technical Summary

Problems solved by technology

[0004] Aiming at the waste problem caused by harvesting ear heads and stalks together in the millet combine harvester in the prior art, the present invention provides a combine harvester header for segmentally harvesting millet stalks and ears and its use method, which has a simple structure and can Harvest the ears and stalks of millet in sections to facilitate subsequent threshing of millet and prevent drum winding, reducing waste of stalks
