Specific embodiment
As shown in Figures 1 and 2, a kind of combined type oat sheller unit of the utility model, including rack 1, is arranged on machine
Casing 2 on frame 1 rolls threshing unit 3 and for carrying out rubbing threshing to oat for oat roll threshing
Rubbing threshing unit 4.Casing 2 includes rolling threshing portion 201 and rubbing threshing portion 202, rolls threshing unit 3 and is arranged on and rolls
In threshing portion 201, rubbing threshing unit 4 is arranged in rubbing threshing portion 202, is rolled threshing portion 201 equipped with feed inlet 203, is wiped
It rubs threshing portion 202 with the hands and is equipped with discharge port 204.Threshing unit 3 and rubbing threshing unit 4 are rolled by i.e. connectable, oat fringe is successively
By rolling 4 threshing of threshing unit 3 and rubbing threshing unit, so as to improve the threshing performance of its oat grain, and use
Milling roller 301 can keep the integrality of stalk, and less stalk crushes.
Rolling threshing unit 3 includes being arranged on rolling the milling roller 301 of 201 internal upper part of threshing portion, being arranged on and roll threshing
The threshing screen 302 at middle part and the first conveying mechanism 303 for rolling lower part in threshing portion 201 is arranged in portion 201.Milling roller
301 are made of rubber material, and quantity is the multiple and setting that is arranged parallel to each other, and is opened up on the circumferential surface of milling roller 301
Be useful for auxiliary threshing and with the spirality convex rib 305 made of rubber material, on two milling rollers 301 of arbitrary neighborhood
The rotation direction of spirality convex rib 305 is contrary setting.
Threshing screen 302 in a ring, two is equipped at intervals in the threshing screen 302 of annular and is used for threshing screen 302
The drive shaft 304 for being tensioned and driving threshing screen 302 to rotate.Threshing screen 302 and drive shaft 304 are similar to belt conveyor knot
Structure, threshing screen 302 are made of metal material, and by articulated connection between grid and grid thereon, make threshing screen 302
It can be rotated by drive shaft 304, be formed in the upper surface of threshing screen 302 and the lower surface of milling roller 301 and accommodate swallow
The gap of the wheat head, the top seed of oat fringe by the differential relative motion of threshing screen 302 and milling roller 301 roll de-
Grain is moved, the spiral shell on milling roller 301 by the rotation driving oat fringe of threshing screen 302 along the length direction for rolling threshing portion 201
Rotation shape convex ribs 305 promote oat fringe to be moved along the width for rolling threshing portion 201, and due to two milling rollers of arbitrary neighborhood
The rotation direction of spirality convex rib 305 on 301 is contrary setting, therefore oat fringe moves in threshing portion 201 is rolled along zigzaggery
It is dynamic.This motion mode makes oat fringe be pushed repeatedly, makes the seed under being ground by milling roller 301 and the cooperation of threshing screen 302
It can smoothly be fallen from threshing screen 302, so as to avoid being rolled repeatedly, effectively reduce the percentage of damage of seed.
In the present embodiment, two sections of threshing screens are equipped with along the length direction for rolling threshing portion 201 rolling in threshing portion 201
302, be equipped with switching mechanism 5 between two sections of threshing screens 302, switching mechanism 5 include torsion shaft 501, along torsion shaft 501 radially
More overturning spike-tooths 502 being disposed on 501 circumferential surface of torsion shaft and the first arc grid being arranged below torsion shaft 501
Plate 503.It rolls threshing course and is divided into two sections, first segment rolls threshing and causes first by the inverting action of switching mechanism 5 afterwards
The seed taken off and be mixed in oat fringe that section rolls threshing course is shaken off down from oat fringe, passes through the first conveying mechanism
303 are delivered to rubbing threshing unit 4, followed by second conveyor structure 404 into cleaning plant, so as to reduce first segment
It rolls the seed taken off in threshing course and is rolled rubbing repeatedly, so as to reduce seed breakage rate.
It is installed to coordinate with large-scale combined harvester, the inclination of threshing portion 201 that rolls in the present embodiment is set
It puts, the feed inlet 203 of oat fringe is located at the top of 303 conveying direction initiating terminal of the first conveying mechanism and positioned at threshing screen 302
Between milling roller 301, and equipped with dedicated conveyer by feed inlet 203 between threshing screen 302 and milling roller 301
Gap is fed.First conveying mechanism 303 is ribbon conveyer, and interval vertical is equipped on the conveyer belt of the first conveying mechanism 303
Multiple baffles 306, the seed to drop in the transmission process of the first conveying mechanism 303 roll threshing portion eventually by being arranged on
The grain leakage collecting boxs of 201 feed ends is collected, to reduce loss.
Rubbing threshing unit 4 includes roller 401, and more are equipped at intervals on the circumferential surface of roller 401 and is divided along roller 401 is axial
The threshing rasp bar 402 of cloth, the lower section of roller 401 be equipped with for threshing rasp bar 402 coordinate with to oat fringe lower part seed into
Second arc screen 403 of row threshing.Roller 401 in the present embodiment is taper, and the second arc screen 403 is semi-cylindrical,
Roller 401 is more than roller 401 close to Lysimachia sikokiana close to the spacing rolled between the one end in threshing portion 201 and the second arc screen 403
Spacing between 405 one end of mouth and the second arc screen 403, makes seed of different sizes on oat fringe can be transferred through roller 401
It is sloughed with the cooperation of the second arc screen 403.
One end of second arc screen 403 is corresponding with 303 conveying direction end of the first conveying mechanism to roll threshing portion 201
It is connected, the other end is equipped with straw outlet 405.The length direction of discharge port 204 along the second arc screen 403 is arranged on the second arc grid
The lower section of plate 403 is equipped with to convey the second conveyor structure 404 of seed in the lower section of discharge port 204, in the second arc screen
403 lower section is equipped with to convey the second conveyor structure 404 of seed, and second conveyor structure 404 is helical feed auger, in spiral shell
It revolves and is equipped with and 403 corresponding opening of the second arc screen along its length in the upper body of conveying auger.Rubbing threshing portion 202
To be co-axially located at the curved cover plate of the top of roller 401, it is equipped at intervals on the intrados of curved cover plate a plurality of for will roll
The big miscellaneous spiral shape conveyed towards 405 direction of straw outlet between 401 and second arc screen 403 of cylinder leads swath 406.
In roller 401 more chargings are equipped with along 401 spaced radial of roller on the circumferential surface of the one end for rolling threshing portion 201
Spike-tooth 407 is equipped with more discharge spike-tooths on the circumferential surface of 405 one end of straw outlet in roller 401 along 401 spaced radial of roller
408.Charging spike-tooth 407 therein, which not only has, takes off the oat fringe of 303 end of the first conveying mechanism to 401 and second arc of roller
Outside function between shape screen 403, it can also make to take off but be mixed on oat fringe by feeding the inverting action of spike-tooth 407
Seed is shaken off from oat fringe, directly avoids seed by rubbing into second conveyor structure 404 by the second arc screen 403
4 rubbing of threshing unit reduces breakage rate.Correspondingly, discharge spike-tooth 408 is dialling oat fringe stalk towards 405 direction of straw outlet
When dynamic, the oat grain being mixed in stalk can be shaken off down, second conveyor structure is entered by the second arc screen 403
In 404, avoid causing to waste.
