Description
The utility model relates to a kind of outfitting tool of large-scale agricultural machinery, the matched corn harvesting bench of particularly large-scale combine.
Existing corn harvesting bench is representative with the corn harvesting bench of U.S. John Deere ﹠ Co. 40 series, 4.5-8.1 kilometer/hour of results speed, feed quantity 2-4.9 Kilograms Per Second, total losses 2.1-6.2% (speed height, the loss increasing), can take in the milpa of height and lodging concurrently.Russia KKH-2.6 type and West Germany west receives the also approaching above-mentioned level of corn harvesting bench that Dole company produces, but their price costs an arm and a leg all more than 10,000 dollars.Yugoslavia and homemade east wind 4L2-5 type 4 row corn harvesting benchs are the equidistant formula of 4 row, and the line-spacing adjustable extent is 60-70 centimetre.Facts have proved that plantation line-spacing and ceding of Taiwan line-spacing differ and surpass 10 centimetres, yield loss is significantly risen.And at present corn planting is because of factors such as manage in mechanical field, interplantings, 3 group of 6 row, and it is a lot of that size is done the variation such as grade in the ranks.And these cedings of Taiwan form the special-purpose ceding of Taiwan of an integral body owing to all be fixed with feeding screw feeder, preceding transmission device and the vertical collection apparatus of corn, and then its volume is big, complex structure, cost height.Because of it is worth too high or because of yield loss is bigger, so can't the large tracts of land penetration and promotion.If directly adopt existing combine harvesting corn, the horizontal rolling of straw shift wheel strengthens the corn gleaning, and can not gather in the crops falling corn, and yield loss reaches more than 25%.Along with industrial expansions such as breed, medicine, food, maize sown area enlarges year by year, and the contradiction of yield loss becomes increasingly conspicuous.
The purpose of this utility model is exactly in order to address the above problem, and provides a kind of harvesting line-spacing adjustable, and cost is low and can reduce supporting the using the row corn harvesting bench of combine that harvest corn loses.
Technical solution of the present utility model:
A kind of combine is supporting to be used the row corn harvesting bench, it includes header frame and the vertical dialing-grain unit assembly of many covers, it is characterized in that respectively overlapping vertical dialing-grain unit assembly is made of main dialing-grain unit and auxiliary dialing-grain unit, wherein main dialing-grain unit by nearside divider and both sides all have on, under collect chain and constitute, on the both sides, under collect chain and all be connected with header frame by transmission case, auxiliary dialing-grain unit is made of nearside divider and elastic straw-pushing rod, the nearside divider of auxiliary dialing-grain unit is connected on the header frame by the auxiliary dialing-grain unit rack faceshield, and all is provided with an auxiliary dialing-grain unit between any two the main dialing-grain units on the header frame.
The utility model adopts the special-purpose ceding of Taiwan of whole corn of the adjustable line-spacing of 6 row, finishes with former grain header to be connected, and it changes convenient, can realize reaping corn or recover two kinds of duties that former rice wheat harvest is cut, and is multiple functional.The utility model is compared with external similar advanced facility, and indexs such as its operating efficiency, results total loss rate are equally matched, and price is more much lower than import, and needn't use foreign exchange.The utility model and Yugoslavia or homemade east wind 4 row corn harvesting benchs compare, and have remedied the latter to little, especially big line-spacing of spy and the defective that do not wait the corn of line-spacing not gather in the crops, thereby have reduced yield loss.And the latter is the 4 row cedings of Taiwan, and the utility model is the 6 row cedings of Taiwan, and not only operating efficiency improves, and more adapts with China southern area corn planting method.The utility model is compared with the rice/wheat combine harvesting corn with direct, and the latter laterally rolls because of straw shift wheel, hits corncob down, and yield loss reaches 25%, and machine is had to manually picking up after receiving.The utility model yield loss rate is then less than 3%, and machine need not manually to pick up after receiving substantially.The utility model has made full use of 1065 grain headers of domestic widespread usage, by simply changeing, promptly becomes the special-purpose grain header of corn, has increased by 1065 function, realizes a tractor serves several purposes.Because the harvest time of corn, paddy rice, Soybean and Other Crops is very approaching, the utility model changes then simple, convenient, and then in autumn harvest rush season, it is more outstanding that its superiority seems, is convenient to penetration and promotion.The utility model has absorbed the multinomial strong point of external advanced facility dialling standing grain, hold up standing grain, picking up aspects such as lodging cane, importing, pays attention to reliability design again especially at aspects such as structure, transmissions, so the performance performance is good in operation, mechanical breakdown is few.
