Background technology
China is Farming big country, with the aggravation of the acceleration and aging of population degree of urbanization process, Neng Goucong
The labour that thing grain gathers in threshing is fewer and fewer, needs to assist harvest grain by thresher machine.Although there is combine harvester,
But it in mountain area plateau band, is limited by landform, must still use independent threshing operations mode.Currently, available on the market de-
Grain mechanical type is various, and structure is also different, although outside feeds intake, structure constantly changes, and threshing core remains unchanged not
There are larger improvement, threshing structure to be relatively fixed, cannot can be adjusted as needed, can not be realized according to real-time working condition adaptive
It should adjust, to reach the dynamic balance state of threshing operating mode, and then reach the consistency of Threshing.Traditional threshing mode one
Aspect causes threshing to be not thorough, and due to the limitation of machine itself, can only be by manually again in order not to waste remaining seed
Secondary carry out threshing, virtually increases hand labor intensity, wastes a large amount of manpower and time, so that threshing work is become front and is divided into
Mechanization, rear portion are divided into manual；Simultaneously because threshing dynamics is uneven in practical threshing course, less serious case leads to broken shell, unfavorable

Rotating vane 06 includes the front end and rear end connected by transition part, and front end raises up, and channel is cut
Face reduces, and is conducive to accelerate air-flow velocity, raised surface makes the air pressure of 06 transition part of rotating vane be reduced, front and back pressure difference
So that air velocity is accelerated, especially 06 front end flow velocity of rotating vane is very fast, and the downwardly convex air-flow velocity in rear end is relatively flat, more
Number air-flow substantially steadily flows through, and since front end high-speed flow generates the attraction of low pressure, 06 front end air-flow of rotating vane is upward
Surface flows away, and causes the gas channel of rear end to widen, causes the air velocity of rear end to be declined, flow through front end in this way
The air velocity of upper surface is faster than lower surface, according to bernoulli principle, the slow place pressure of the fast local pressure ratio flow velocity of flow velocity
Power is small, i.e., 06 following pressure of rotating vane is more than top, and pressure official post aerofoil profile obtains a upward power, but due to rotating vane
06 fixes, therefore generates downward air-flow to generate " wind-force ", achievees the effect that expected flabellum；Rotating vane 06, which is located at, to be rolled
23 upside of cylinder shell, and its root of blade is away from 23 upside 100mm of drum housing, the effect of rotating vane 06：
1) it prevents from being flown out feeding mouth by manipulating object, causes safety accident；

78 compression 76 downlink of the 6th floating spring of seat, and the spline for cutting off transmission control spline housing 11 and transmission control splined shaft 12 is nibbled
It closes, to instantaneous trip power, avoids further damaging by manipulating object, drum housing 23 and guide housing during this downlink
Gap width between 24 inclined-planes rapidly becomes larger, and to which moment eliminates overload, system restores original job shape automatically after overload is eliminated
State, when occurring unusual condition or accident when operation, operation dynamic Control control stick 19 passes through dynamic Control control handwheel 63 and the
Four deep groove ball bearings 70 drive transmission control spline housing 11, and rapidly downlink moment cuts power, to avoid unusual condition or accident
Further extension；
When job load increases suddenly, operation part downlink, dynamic Control control handwheel under the promotion of load axial thrust load
63 drive 90 downlink of third feedback control bar by dynamic Control control stick 19, and the first feedback control bar 85 is in third feedback control
Around the middle part active pin shaft rotation of the first feedback control bar 85 under the action of bar 90, the first feedback control bar 85 is anti-by second
It presents control-rod 87 and pushes feedback 82 uplink of drive link, feedback drive link 82 is by feeding back flexural pivot connecting rod 81 and feedback 83 band of axis pin
24 uplink of action-oriented cover so increases the relative position between guide housing 24 and drum housing 23, and moment reduces job load, from
And continuing traveling downwardly for operation part is prevented, with the decline of job load, operation part restores uplink, while in servo feedback control
24 downlink of guide housing under the action of mechanism processed, so increasing and decreasing with external inventory, entire servo feedback control machine
Structure, which is in a dynamic change, repeats the above-mentioned method of operation, so that job load is in a kind of pre-designed dynamic equilibrium
State ensures whole threshing operations effect.
