Baby combine
Technical field
The present invention relates to a kind of agricultural machinery, particularly relate to a kind of baby combine.
Background technology
For knob and some compare little soils, plot, the support of miniature farm machinery is can't do without in the realization of agricultural machinery, and current miniature farm machinery is realized simple or single function often, or the scaled down version of big machinery, this tends to occur that results are of low quality, adaptability is not strong, and more and more can not meet the demand of peasant to high-quality agricultural machinery.
Existing baby combine general main comprise there is header part, middle conveying plant, middle transport portion, actuating element, threshing part, the device of delivering grain, cleaning plant, control panel, lifting part, running gear, clearly grain partly, power section, there is following defect in it;
1, header part: be mainly straw shift wheel, be not easy to dismounting for existing straw shift wheel in the situation that meeting basic function at present, and have a strong impact on the work of straw shift wheel when contact site generation corrosion, and affect the life-span of straw shift wheel.In the crop harvesting of differing heights, in order to meet the crop that enters that elastic claw can be vertical, and play the effect of dialling standing grain, just need to there is the device of an eccentric adjusting, thereby reach the needs of results, reduce the grain loss while gathering in.
2, threshing part: be mainly detachment roller, for reaper thresher, designing irrational device will affect Threshing.In prior art, the threshing performance of grain header detachment roller often can not meet requirement, caused and when threshing, wasted a certain amount of grain, and detachment roller also can cause the not smooth situation such as obstruction even of eliminating during straw row;
3, cleaning plant: crop is after entering sheller unit; through impacting of threshing auger; grain or wheat depart from stem stalk; a large amount of foreign material are discharged to the external world by Lysimachia sikokiana plate; a small amount of stem stalk is blended in and in grain, enters together the passage of putting out cereal; through cleaning of cleaning mechanism, can obtain the cereal that cleannes are higher.General cleaning plant is after cleaning grain fan, and light foreign material are directly discharged body, can cause the cereal mixing in foreign material directly to be discharged, and have increased the loss of cereal crops of grain header.
4, lifting part: due to the difference of kind, the difference in height of paddy rice and wheat is very large also, in order to improve the adaptability of baby combine, often needs the height that the cutter of baby combine has certain limit with respect to ground to regulate.At present, what for the jacking system of small-sized associating rice/wheat combine, generally adopt is single hydraulic lifting or drag-line lifting, also can reach the effect of certain lifting.But hydraulic lifting can not improve adjustable height by increase stroke simply; Drag-line jacking system except stroke cannot meet the demands and also lifting process relatively require great effort;
5, running gear: at present, known small harvester gearbox mainly contains two kinds of structures: the first consists of housing, change-speed gearing, differential mechanism, left and right output shaft brake device, and its structure is more complicated, brake device water inlet was easily lost efficacy; It two is comprised of housing, change-speed gearing, tooth sector, output shaft etc., and its housing output shaft position intensity existing problems, are not easy to assembling.
