Summary of the invention
The object of the invention is to: the shortcoming existing for above prior art, propose the cotton device of a kind of rake that can in time unginned cotton be harrowed away, thereby the cotton after assurance is plucked is transferred conveying plant in time smoothly to.
In order to reach above object, the cotton device of rake of the present invention comprises the rotating shaft being arranged in picking desk frame, and described rotating shaft comprises driving shaft and the driven axle that distributes up and down and be parallel to each other; Described driving shaft and driven axle are equipped with respectively by harrowing drive sprocket that cotton chain is in transmission connection and by movable sprocket, between the cotton chain of described rake at two ends, interval is fixed with the cotton thick stick of the rake parallel with rotating shaft, the cotton thick stick of described rake along its length interval is fixed with elasticity rake teeth, and described elasticity rake teeth extends with the angle that is tangentially flare with the cotton chain of rake towards the cotton chain movement rightabout of rake.
The angle of especially described flare is 5 °-15 °.
Adopt after the present invention, because the cotton device width of rake reduces greatly, thereby the picking point that makes to be positioned on broach significantly reduces (can be reduced to 50 millimeter) with the application point distance of dialling cotton wheel.Like this, cotton under plucking is dialled in time, can not be deposited on ratch, therefore effectively avoided the cotton of piling up to contact and produce drawstring with follow-up branch bar, hanging branch cotton and the cotton that lands have obviously been reduced, reduce the loss of unginned cotton, and do not affected shape and the layout of multiple comb-type cotton stripper upper strata broach, overcome the defect of cotton and the easy jam of branch.
The present invention further improves, and described elasticity rake teeth bends to when its outermost end is when described driving shaft and driven axle connect with the heart extended line, described outermost end moment the direction of motion with described in the extended line that connects with the heart vertical.
Like this, elasticity rake teeth is basic identical in state and the prior art of dialling cotton useful effect point, in the perfect condition perpendicular to broach plane intersection point place, therefore can keep dialling cotton effect.
As can be seen here, the present invention is by rationally design cleverly, with simple structure, realize the conception from picking point by unginned cotton rake in time, both solved comb-tooth-type cotton picker and lost greatly, contain an assorted high difficult problem, also solved the difficult problem that multiple comb-type cotton stripper upper strata broach row cannot arrange.
