Abstract

The invention relates to a combine harvester gas blowing type divider suitable for coarse grain harvesting. A gas blowing type dividing mechanism comprises a fan, an gas flow pipe I, an gas flow pipe II, an gas flow pipe III, a left divider sleeve and a right divider sleeve; the left divider sleeve and the right divider sleeve are mounted on a cutting table frame; a plurality of gas guide pipes are arranged at one end, extending into the left divider sleeve, of the gas flow pipe III as well as at one end, extending into the right divider sleeve, of the gas flow pipe I; gas holes which are identical with the gas guide pipes in quantity and are matched with the gas guide pipes in position are formed in each of the left divider sleeve and the right divider sleeve. The divider provided by the invention has the benefits that in the driving process, to-be-harvested and unharvested crops are better divided through the inner gas holes and the outer gas holes; the gas holes above the divider can effectively blow open the intertwined crops; through gas blown in three directions, the purpose of dividing the intertwined crops can be better realized.

Description

technical field

[0001] The invention relates to a grain dividing device, in particular to an air-blown grain dividing device for a combine harvester suitable for harvesting miscellaneous grains. Background technique

[0002] Miscellaneous grain crops such as millet, after maturity, the ear of the grain droops, the plant bends, and the ears of grain are intertwined and entangled with each other. How to effectively divide the grain and reduce the loss caused by the pulling of the grain has become a major technical problem that restricts the harvest of millet.

[0003] At present, in the actual harvesting, the growth of millet is getting better and better. There are problems such as unreasonable structure in the existing grain divider of the harvester. Pulling causes the ears of grain to fall off, and the grain outside the grain divider sticks to the outside of the header, causing the gap between the reel and the bracket to easily entangle the grain when the reel rotates at hig...
