Abstract
For the floating control axial-flow type methods of threshing of chia threshing, threshing operations are implemented using floating control axial-flow thresher, plays nature guide using gravity, electric power and human cost is effectively reduced；Transmission shaft is driven to rotate drum housing rotation by motor simultaneously, stick is smashed by being arranged on drum housing three to rotate and then realize threshing operations, and the dynamics of threshing is adjustable during threshing operations, it is effectively reduced because threshing dynamics is uneven, and then the loss for causing the chia seed after threshing destroyed, when occurring unusual condition or accident in threshing course, operating dynamic Control control stick, rapidly downlink moment cuts power by dynamic Control control handwheel drive transmission control spline housing, to avoid unusual condition or accident further expansion.
Description
Technical field
The present invention relates to seed shatter technical field more particularly to a kind of floating control axis for chia threshing
Streaming methods of threshing.
Background technique
Chia (Salvia Hispanica L) is rich in polyunsaturated fatty acid triglycercide alpha-linolenic acid
(ALA, a kind of omega-fatty acid) and linoleic acid (LA, a kind of essential ω -6 fatty acid), the ratio of linolenic and linoleic
Example is about 3.3:1；And its seed, also known as odd refined seed, odd Asia seed, unusual son, the seed containing about 33% are oily, 21% protein,
41% total dietary fiber and high-content minerals；Because its seed is rich in high-cellulose, meets water and easily becomes gel-like, expand more times,
It can be formed membranaceous in the stomach for entering people, be covered in stomach wall, make one to keep satiety for a long time, while be continuously human body and energy is provided
Amount, is a kind of healthy food.
The axial-flow thresher used at present for chia is divided into vertical and horizontal two major classes, in vertical thresher
Raw material vertically squeezes to achieve the effect that threshing through drum movement and fixed baffle；Raw material enters laterally machine in horizontal thresing machine
Body, the extruding through roller and sieve reach the effect of threshing, seed are separated, but both modes have threshing and do not do
Only, it finally also needs manually to remove, the problem of large labor intensity；Simultaneously because threshing dynamics is uneven in practical threshing course, into
And cause the chia seed after threshing destroyed, seriously affect chia seed quality；Especially in threshing
When occurring unusual condition or accident in journey, can only by close thresing machine switch, caused by loss it is bigger.
Summary of the invention
Technical problem solved by the invention is to provide a kind of floating control axial-flow type for chia threshing
Methods of threshing, to solve the problems in above-mentioned background technique.
Technical problem solved by the invention is realized using following technical scheme:
It is real using floating control axial-flow thresher for the floating control axial-flow type methods of threshing of chia threshing
Threshing operations are applied, the first adjustment spacer thickness of change floating control axial-flow thresher is first to adjust the 4th floating spring
Pretightning force, the second floating spring seat of rotation adjust the pretightning force of the first floating spring and the 5th floating spring, change second adjustment
The thickness of gasket is to adjust the pretightning force of third floating spring, then rotates third floating spring seat and adjust the pre- of the second floating spring
Clamp force, and total resultant force of the first floating spring, the 4th floating spring and the 5th floating spring pretightning force is equal to the second floating spring
Add the related total resultant force for being supported part gravity to the pretightning force of third floating spring, has adjusted the second floating spring seat and third is floating
After the position of flexible spring seat gives pretightning force, the second floating spring seat, the first locking nut lock are locked by the second locking nut
Tight third floating spring seat；Adjust the amount of screwing of control spring base and lower control spring base again to adjust the 6th floating spring
Pretightning force, and the pretightning force is greater than supported associated components gravity summation, complete upper control spring base to be adjusted and lower control bullet
After the position of spring abutment gives pretightning force, the position of the relatively upper control spring base of lower control spring base is locked by third locking nut
It sets；The thickness of sixth gear circle and the 4th adjustment gasket is adjusted again and then adjusts transmission control spline housing with respect to dynamic Control control stick
Position；The spline fitted length of nut adjustment transmission control splined shaft and transmission control spline housing is turned up in rotation, is to control
The automatic control power of system is cut off and engaged transmission, passes through tune behind good transmission control splined shaft to be adjusted and transmission control spline housing position

Rotating vane 06 includes the front end and rear end connected by transition part, and front end raises upward, and channel is cut
Face reduces, and is conducive to accelerate air-flow velocity, raised surface reduces the air pressure of 06 transition part of rotating vane, 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 airflow 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 greater than top, and pressure official post aerofoil profile obtains a upward power, but due to rotating vane
06 is fixed, 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
The upside of cylinder shell 23, and its root of blade is away from 23 upside 100mm of drum housing, the effect of rotating vane 06:
1) feeding inlet that flown out by manipulating object is prevented, safety accident is caused；
2) it prevents from being entered bearing clearance by manipulating object, generates abrasive wear, and then accelerate the rate of wear of bearing and axis,
Axis or bearing failure are finally caused in advance, influence machine service life；
3) time for being placed in 23 threshing zone of drum housing by manipulating object is lengthened, threshing efficiency is improved；
