Description
Technical field
The invention belongs to agricultural mechanical field, in particular to sorting purpose device used in a kind of combine harvester, is one
The anti-blocking cleaning plant of segmented and its control method of the variable angle of heel of kind.
Background technique
Cleaning is important link in agricultural production, and material, which needs for seed to be separated from the mixture after harvesting, to be come,
Obtain clean seed.Combine harvester is in hillside fields operation, due to operation ground inclination etc., combine harvester lateral tilting
Tiltedly, easily there is the case where sorting screen side material leads to accumulated plugging too much;For longitudinal axial flow detachment roller, taken off under threshing intaglio plate
Material out is also biasing when reaching compass screen surface.Both the above situation will lead to compass screen surface and be born using insufficient, sieve side
Situations such as weighing.When a kind of generation of both the above situation, if harvest object moisture it is relatively more, i.e., material humidity when, can add
Weight left and right sides sieve pore blockade tendency.
The patent of invention of Patent No. CN103447230B discloses a kind of non-constant amplitude sorting purpose sieve, by rack, motor,
The part such as vibrating screen, feed inlet, discharge port and vibrating mechanism forms, and mainly adds grade connecting rod by using eccentric wheel
Shaker vibration is driven, and the series of front and back connecting rod is inconsistent, makes the direction of vibration diversification of compass screen surface, can reach better
Screening effect.It is usual only in a kind of amplitude that the technical solution of the patent disclosure considers vibrating screen mechanism in existing sorting screen
Under the conditions of work, the motion profile at each position of vibrating screen is identical, and the amplitude and oscillation intensity at each position are also identical, thus cannot solve
Sieve pore blockade problem caused by certainly sorting screen feeding end and discharge end material thickness are inconsistent is different by amplitude before and after sorting screen
This problem is well solved;The patent of invention of Patent No. CN104084372B discloses a kind of based on planar linkage mechanism
Amplitude variable cleaning plant, be grouped as by material supply portion, material screening part and drive control part, it is main by real-time
The suspension point and initial tilt of the preposition sunpender of screen box are adjusted, the amplitude of screen box front end is changed, is kept away in the variation of material feed quantity
Exempt from material accumulation appearance in the screen box front end the case where;Both the above invention solves the inconsistent possibility of material thickness before and after compass screen surface
The accumulated plugging problem of generation is suitable in grading operation, but it is left in hillside fields operation to solve combine harvester
Right bank cause sieve side material it is too many caused by accumulated plugging problem.
Summary of the invention
The present invention is solution when hillside fields carries out the operation of mechanization combining in view of the deficiencies of the prior art mentioned above
The problem of biasing accumulated plugging of side material caused by compass screen surface tilts, the segmented for providing a kind of variable angle of heel are anti-blocking clear
