Abstract
The invention discloses a row-threshing type threshing device of a whole-feeding small combine harvester, relating to small combine harvesters. The threshing device is characterized in that a threshing cylinder and a rice straw separating bowl are arranged in a machine frame; a threshing cylinder screen is arranged outside the threshing cylinder; a threshing cylinder shield is arranged outside the threshing cylinder screen; the lower part of the threshing cylinder shield is provided with a storage barn; a helical blade propeller is arranged in the rice straw separating bowl; the lower part of the rice straw separating bowl is provided with a rice straw separating bowl screen; the upper part of the rice straw separating bowl is provided with a rice straw separating bowl shield; a straw outlet is arranged on the rice straw separating bowl shield; a discharging port of the threshing cylinder screen is connected with a feeding port of the rice straw separating bowl screen; a conveyer belt is connected on the machine frame; and the rear end of the conveyer belt is connected with a feeding port of the threshing cylinder. The threshing device disclosed by the invention has the advantages of being simple in structure, scientific and reasonable in design, equivalent and uniform in feeding due to automatic falling and arrangement of wheatears, and light in load, small in damage and high in cleanness in rice straw separation due to adoption of kneading threshing.
Description
Technical field
The present invention relates to baby combine, more specifically relate to a kind of full feeding baby combine and get rid of the formula sheller unit.
Background technology
Grain header is the harvesting machinery of crop such as harvesting paddy and wheat etc., in recent decades, and the rice/wheat combine of domestic-developed; Be divided into full feeding and partly feed two kinds; Can both once accomplish operations such as harvesting, threshing, millet straw separation, foreign material screening, the realization machine is crossed paddy and is received, directly the harvesting machinery of pack.Present both at home and abroad traditional full feeding operation principle and threshing mode all is to raise that fringe is mixed to take off its acting process: cut → raise fringe → compile → carry → mix and take off.The fringe of raising mixes and takes off, and is provided with spiral conveying mechanism, and standing grain fringe feed quantity is uneven, and threshing barrel is carried out and forced to beat the threshing of fringe formula, and the millet straw released state that takes place this moment must be that bar stem, arrow leaf are pulverized, and the threshing load is very big, percentage of impurity extra-high-speed after the threshing, and the grain breakage is bigger.Simultaneously, traditional baby combine separating mechanism is complicated.For this reason, have much room for improvement.
Summary of the invention
Technical scheme of the present invention is: a kind of full feeding baby combine is got rid of the formula sheller unit, it is characterized in that, in frame, is provided with threshing cylinder and millet straw cylinder; Threshing cylinder is provided with the threshing cylinder screen cloth outward; The threshing cylinder screen cloth is provided with the threshing cylinder guard shield outward, and the bottom of threshing cylinder guard shield is provided with the helical blade propeller for the storage granary in the millet straw cylinder; The bottom of millet straw cylinder is provided with millet straw cylinder screen cloth; The top of millet straw cylinder is millet straw cylinder guard shield, on millet straw cylinder guard shield, is provided with grass outlet, and the discharging opening of threshing cylinder screen cloth links to each other with millet straw cylinder screen cloth charging aperture; On frame, be connected with conveyer belt, the rear end of conveyer belt links to each other with the charging aperture of threshing cylinder.
Described full feeding baby combine is got rid of the formula sheller unit, and its threshing cylinder is the thin plate cylinder, evenly is provided with 4-8 root spiral arc tooth bar at the outer wall of cylinder.
Described full feeding baby combine is got rid of the formula sheller unit, on the conveyer belt bracing frame, is provided with the hydraulic lifting oil cylinder, and conveyer belt is swung around the rear end.
Described full feeding baby combine is got rid of the formula sheller unit, described millet straw cylinder be arranged in threshing cylinder above, be provided with the straw arc on the top of cylinder guard shield inwall.
Described full feeding baby combine is got rid of the formula sheller unit; Its threshing cylinder is the thin plate cylinder, evenly is provided with 6 spiral arc tooth bars at the outer wall of cylinder, and 3 is left-handed spiral arc tooth bar; 3 are the spiral arc tooth bar of dextrorotation; The left-handed spiral arc tooth bar and the spiral arc tooth bar of dextrorotation alternately, described millet straw cylinder be arranged in threshing cylinder above, be provided with the straw arc on the top of cylinder guard shield inwall.
Operation principle of the present invention: full feeding baby combine of the present invention is got rid of the formula sheller unit; Its working procedure is: after the standing grain fringe in a row of grain header upper cutter knife combing cuts; Naturally fall to being laid on the conveyer belt; Conveyer belt evenly is transported to threshing cylinder fast with standing grain fringe equivalent, and the standing grain fringe is under the relative mill sassafras of spiral arc tooth bar on the threshing cylinder and threshing cylinder screen cloth, thus the rubbing threshing of realization millet straw; Remaining standing grain fringe after the rubbing continues to get into the millet straw cylinder, and the helical blade propeller carries out the high speed Lysimachia sikokiana, and grass is got rid of from grass outlet, and millet straw cylinder screen cloth screens residual cereal simultaneously, and cereal all is pooled to the storage granary, paddy to be gone out.
Beneficial effect of the present invention: full feeding baby combine of the present invention is got rid of the formula sheller unit, has relatively simple for structurely, and design science is reasonable, and the standing grain fringe is from the row shop that falls, and feeding equivalent is even, the rubbing threshing, and load is light, and damaged little, millet straw separates clean.It is complicated to have overcome conventional small combine separating mechanism, and the threshing load is big, and efficient is low, and the grain breakage is bigger, defectives such as percentage of impurity height.
