Description
Technical field
The utility model relates to the grain header technical field, relates in particular to a kind of harvester threshing cleaning plant.
Background technology
At present, domestic combine just develops towards medium-and-large-sizedization direction, increasing along with the widening of swath, feed quantity, the needs of the incompatible development of original middle-size and small-size single drum threshing cleaning plant, and, the bad adaptability of single drum threshing cleaning plant, particularly for the combine of operation under wet environment, this phenomenon is more outstanding.
The utility model content
Technical problem to be solved in the utility model is: a kind of operating efficiency height is provided, and adaptability is strong, the harvester threshing cleaning plant that threshing performance is high.
For solving the problems of the technologies described above, the technical solution of the utility model is: the harvester threshing cleaning plant, comprise sheller unit and cleaning plant, described sheller unit comprises that a cut flow roller is positioned at described cut flow roller rear side and the horizontal axial-flow type drum parallel with cut flow roller with one, described cut flow roller downside is provided with the cut flow roller notch board, and the downside of described axial-flow type drum is provided with grid concave plate.
Because described sheller unit comprises that a cut flow roller is positioned at described cut flow roller rear side and the horizontal axial-flow type drum parallel with cut flow roller with one, cereal has prolonged the threshing time through the two-stage threshing, has improved threshing performance.Simultaneously, cereal is shed through the cut flow roller threshing, tangentially enters axial cylinder, and speed is fast, and the efficient height makes its advantage that has possessed tangential cylinder and axial-flow type drum simultaneously, has improved the adaptability of grain header.
As a kind of improvement, described cut flow roller notch board is provided with auxiliary threshing tooth, the spike-tooth that described auxiliary threshing tooth is an adjustable in length.These auxiliary threshing teeth can improve the threshing performance of cereal, the harvest operation that difficulty is taken off crop varieties has adaptability preferably, the effect that auxiliary threshing tine length is regulated is, when the threshing difficulty of cereal increases, auxiliary threshing tooth is increased, thereby the grain of beating that has increased between auxiliary threshing tooth and the cut flow roller spike-tooth amasss, and has improved threshing performance; When the threshing difficulty of cereal reduces, auxiliary threshing tooth is shortened, thereby the grain of beating that has reduced between auxiliary threshing tooth and the cut flow roller spike-tooth amass, and has reduced percentage of damage.
Improve as another kind, described cleaning plant involving vibrations sieve, described vibratory sieve involving vibrations screen box, the screen box body of described vibrating screen box is provided with upper sieve and lower screen, described vibrating screen box also comprises the shuttle board that is installed on described screen box body and is positioned at the upper sieve front side, and is installed on described screen box body and is positioned at the tail sheet of described lower screen rear side.The front end of described lower screen and screen box body flexibly connect, and the first angular adjustment slotted hole of screen box body is fixed in the rear end of lower screen, and the front end and the lower screen of described tail sheet are hinged, and the second angular adjustment slotted hole of screen box body is fixed in the rear end of tail sheet.
Grain after the threshing falls into vibratory sieve through grid concave plate, at first through shuttle board, makes material uniform, has reduced the accumulation of material at the upper strata compass screen surface.Because the bearing of screen box body and lower screen and tail sheet is equipped with the angular adjustment slotted hole, thereby, the angle of inclination of lower screen and tail sheet can be regulated, increase the inclination angle of lower screen and tail sheet, can increase the resistance of wind, reduce because the grain loss that wind causes, otherwise, reduce the inclination angle of lower screen and tail sheet, can reduce the resistance of wind, improve the cleaning efficiency of cleaning plant.Thus, can make the user reduce cleaning loss and improve between the cleaning efficiency and find an optimal balance point.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Accompanying drawing is the structural representation of the utility model embodiment.
Embodiment
