A kind of millet combined harvester

Technical field

The utility model is related to crop harvesting technical field more particularly to a kind of millet combined harvesters.

Background technology

In recent years, coarse cereals consumption demand is significantly increased with the popularization and market of domestic high-quality hybrid millet, millet Production starts to be able to pay attention to and expand, and the Production Gain and plantation enthusiasm of peasant also greatly improve.However, millet is influenced at present Production maximum " bottleneck " surely belongs to harvest.

Millet belongs to small crop, the green maturation of stalk band, and ripe grain ear hangs low, and mutually entwining property is big, and it is tight that ceding of Taiwan both sides twist fringe Weight；Grain ear seed is small, grain is light, and paddy code detach difficulty with stalk during harvest, and seed is not easy to purify, and carries secretly and cleaning loss percentage height, Damaging the problems such as serious protrudes.

At present, seen there are three types of the types harvested for millet, a kind of is the shoe using single longitudinal axial flow ratch roller shattering Band machine, a kind of is the tracked machine using double transverse-axis-flow drum with rasp bars shattering, and another kind is using single crosscutting flow liner rod drum threshing Wheeled machine.The former, using single longitudinal axial flow ratch roller, threshability is strong, and the threshing time is long, you can with harvest rice, wheat, Rape can also suitably change the means such as roller or notch board parameter according to received agrotype to harvest soybean, Semen Coicis, millet etc. Seed class crop, extremely well-adapted belong to " omnipotent " threshing system.But unfortunately hitting power kneading force greatly in threshing course Small, powerful impact force is not only difficult to control percentage of damage, is also also easy to produce a large amount of crushing straws and cleans what is brought together to lower Load increases.Secondly, using double transverse-axis-flow drum with rasp bars, as a result of two overall length drums with rasp bars, powerful rubbing rate The shell of millet can be destroyed with long-time screw formula threshing and easily makes percentage of damage index exceeding standard, which is equally also not suitable with Harvest rice.The latter, though also using the very strong full rasp bar threshing of kneading force, single crosscutting stream mode to the crop threshing time very Short, stalk is more complete after taking off, and fringe rate of breaking is low, is conducive to subsequent processing.It is disadvantageous that since its impact capacity is relatively weak, The threshing time is again short, and threshing performance is general, is not suitable for the difficult de- crop of harvest rice etc., when feeding that uneven, cereal humidity is larger, Threshing quality is decreased obviously, and adaptability is low, is unfavorable for a tractor serves several purposes.It is therefore only small to harvest less than 4 meters in working width at present Still there is utilization in wheeled type based on wheat, soybean, and the type of the difficult de- crop of or harvest more demanding to loss late is gradual It is substituted by double or three crosscutting stream rollers, single longitudinal axial flow drum with rasp bars.It is general in the mainframe of American-European 6 meters and above working width All over using double longitudinal axial flow drums with rasp bars.

Have been used at present vibrating screen that millet is cleaned also there are three types of.One kind is that double-deck fish scale sieve adds four straw walkers to shake Dynamic sieve, the used by oscillating screen is in all kinds of wheeled types, due to can effectively prevent short stem, broken after double-deck fish scale sieve angle leveling Paddy code, blade etc. are miscellaneous remaining into collection grain auger, and four straw walkers are to miscellaneous remaining processing energy such as short stem, empty paddy code, blades Power is again very strong, can easily adapt to clean millet emersion object.But this is complicated, takes up space big, caterpillar band self-propelled type It can not use totally when being limited by space.Second is upper strata adjustable angle sieve, and lower floor weaves sieve vibrating screen.Relative to The former, which is chiefly used on caterpillar band self-propelled type, and upper strata is the board-like sieve of adjustable angle, and lower floor is punching steel plate Or braided steel wire web frame, based on harvesting rice and wheat and larger seed crop, for fine grain crop, need the board-like sieve in upper strata Piece opening is turned down, and lower floor replaces smaller mesh braided steel wire net and coped with, and adds four keyed by original text relative to double-deck fish scale sieve For device vibrating screen, processing capacity is slightly weak with adaptability.The third be commonly used on rape harvest machine without installation tail portion by The Double-level Reticulated chip vibrating sieve of original text device, the vibrating screen is due to eliminating tail portion separator ridlle, though the miscellaneous remaining ability of long stalk is thrown backward Weakened, but simultaneously also because greatly reduce it is secondary take off feedback again treating capacity due to reduce percentage of impurity, therefore be usually used in harvesting To taking off on crop of less demanding again.
