Specific embodiment
The invention embodiment is described in detail with reference to the accompanying drawing.A kind of combined harvester cleaning fan wind
Regulating mechanism is measured, is fixedly mounted with left clutch driven member 5 and right clutch driven member 14 respectively on the left and right end of jackshaft 16,
It is fixedly mounted with regulating wheel 7 at position on the jackshaft 16, between left clutch driven member 5 and right clutch driven member 14,
In the regulating wheel 7 can circle swing hinge load bar 15, concentric point at the left and right side position of the jackshaft 16
Not Pei Zhi left axle 3 and right axle 9, the left disc 2 of relatively turnable suit in 3 left-hand portion of left axle, left clutch is actively
Part 19 is packed on the right part of left axle 3, and the left clutch driving link 19 is with left clutch driven member 5 in the cooperation that contacts with each other
Or cooperation is disengaged, it is successively fixedly mounted with right disc 10 and belt pulley 11 from left to right on 9 right side of right axle, on the right side
Right clutch driving link 20 is fixedly mounted on the left part of axis 9, the right clutch driving link 20 is in phase with right clutch driven member 14
Mutually be engaged or disengage cooperation, the left and right both ends of fan blade 4 rotatably respectively with left disc 2 and right disc 10
Be hinged, the outer end of the connecting rod 15, which can be controlled, to be hinged to mobile with fan blade 4, the stepper motor 1 of fixed setting with
Left axle 3 connects, and is fixedly mounted with left bearing 17 and right bearing 18 respectively in the inner hole of the left axle 3 and right axle 9, reversal means axis 12 can control
It is mounted in 18 inner hole of left bearing 17 and right bearing to mobile insertion support, on the left and right side of the reversal means axis 12, position
Left clutch reversal means 6 and right clutch reversal means is respectively set at position between left clutch driven member 5 and right clutch driven member 14
8, the left clutch reversal means 6 and right clutch reversal means 8 contact and match with left clutch driven member 5 and right clutch driven member 14 respectively
It closes, the reversal means axis 12 is connect with the bidirectional hydraulic oil cylinder 13 of fixed setting.
Operation is in use, outer defeated rotary power drives right axle 9 and the rotation of right disc 10, at this time right clutch by belt pulley 11
Device driving link 20 and right clutch driven member 14 are in the engagement state being engaged, and drive 16 synchronous rotary of jackshaft, and this
When left clutch driven member 5 and left clutch driving link 19 be in and disengage the off-state of cooperation, stepper motor 1 and a left side
Axis 3 does not rotate, and the right disc 10 of rotation drives left disc 2 to rotate by fan blade 4, and fan blade 4 does not generate deflection, cleans
The air quantity of blower is constant.When needing to adjust change cleaning fan air quantity, stepper motor 1 is opened, and make its revolving speed and belt pulley
11 revolving speeds are identical, start bidirectional hydraulic oil cylinder 13, extend driving reversal means axis 12, left clutch reversal means 6, a left side by hydraulic oil cylinder rod
