Abstract
The utility model relates to a stepped tangential cross flow multi-roller threshing-separating-cleaning device. The stepped tangential cross flow multi-roller threshing-separating-cleaning device comprises a threshing and separating system and a cleaning system, wherein the threshing and separating system comprises a tangential flow roller and two transversely placed axial flow rollers, as well as concave grids and top caps, which correspond to three threshing rollers, and further comprises a grass chopping device and transitional plates between the concave grids; the cleaning system comprises a slide plate, a shake plate, a vibrating screen, a blower, a grain conveying auger and an impurity auger. According to the utility model, the axes of the three rollers are not on the same horizontal plane but stepped, so that materials discharged from a threshing chamber in front can be favorably thrown to another threshing chamber at the back along the tangent line and have low probability of blockage at the transition parts between the threshing chambers, and the bottoms of the three concave grids are on the same line and form an included angle with the horizontal line to ensure equal distance between the shake plate added to the cleaning device and all the concave grids; the grass outlet side of a second transversely placed axial flow roller is shorter than a first transversely placed axial flow roller, so that the grass outlet shifts to the middle to ensure that grass getting out of the grass chopping device cannot be thrown to un-harvested crops and can be thrown fully and uniformly. The stepped tangential cross flow multi-roller threshing-separating-cleaning device can satisfy the harvest requirement for large feeding amount of crops, and is high in harvest efficiency, strong in threshing and separating capabilities, low in cleaning loss and high in cleaning efficiency.
Description
Technical field
The utility model relates to crops mechanical threshing separator and cleaning plant manufacturing technology field, that a kind of staged is cut crossing current multiple-roll threshing-separation-cleaning plant concretely, can be widely used in gathering in the crops paddy rice, wheat, the high-performance results of rape, barley and beans etc.
Background technology
Along with the continuous expansion of Monitoring of Paddy Rice Plant Area, popularizing of the raising of output and high-yield rice, requires combined harvester guaranteeing under the prerequisite of superperformance, to efficient, high-power, large feed quantity future development, to boost productivity in recent years.The transverse-axis-flow existing in the market or cut stream and installed threshing separator that transverse-axis-flow combines, modal single cylinder have a single horizontal axial-flow type drum installed threshing separator, the installed threshing separator that has cut flow roller and single horizontal axial-flow type drum combination of twin-roll and the installed threshing separator of horizontal Double axial-flow drum combination, the processing capacity of these three kinds of installed threshing separators is all limited, particularly when the luxuriant paddy rice of results stalk leafiness, easily stop up, can not meet large feed quantity, gather in the crops requirement efficiently.The installed threshing separator of existing twin-roll and three cylinders, the axis of cylinder all in the same horizontal line, backward during a threshing chamber transition, can not make material tangentially throw by previous threshing chamber at material, easily causes transition position to have some setbacks and even stops up.In recent years, administration request is forbidden crop straw burning, a stubborn problem that is treated as peasant of stalk, therefore a lot of peasants require directly stalk to be pulverized in crop combining, process in the also field of being convenient to the later stage, horizontal axial flow twin-roll installed threshing separator on market, position due to grass outlet avris after machine, near both sides standing crop on vehicle heading, from stalk smashing apparatus grass out, easily shed standing crops, reduce efficiency of crop, moreover, grass outlet is not in the centre of machine, from stalk smashing apparatus grass out, can not expire width evenly sheds, be unfavorable for follow-up also field processing.On the other hand, the in the situation that of large feed quantity, the mass ratio of emersion object is more, existing cleaning plant can not meet the results requirement of large feed quantity, if emersion object directly drops on vibratory sieve, can make to vibrate on-the-sieve material inhomogeneous, the cleaning load that increases vibratory sieve, makes to clean deleterious.Moreover all in the same horizontal line, it is unequal that notch board is sieved to the distance of shuttle board of inclination to existing cylinder axis, can make the material falling from concave grate pile up or make the material on shuttle board inhomogeneous at shuttle board.
Summary of the invention
The purpose of this utility model is to overcome the technical disadvantages existing in above-mentioned installed threshing separator and cleaning plant, propose a kind of staged and cut crossing current multiple-roll threshing-separation-cleaning plant, to meet the results requirement of the crops such as paddy rice, wheat, rape, barley and beans of large feed quantity.
