Description
Technical field
The utility model relates to agricultural machinery technological field, particularly relates to a kind of with the combined harvester gathering in the crops the fine grain crops such as millet and cleaning plant thereof and millet cleaning and sorting system.
Background technology
In recent years, along with the popularization of domestic high-quality hybrid millet and market are to the significantly increase of coarse cereals consumption demand, millet produced and is paid attention to and expand, and Production Gain and the plantation enthusiasm of peasant improve greatly.But, because millet belongs to little crop, relative to wheat, paddy rice, corn, quality grain is little, thousand kernel weight only has 2.4 ~ 3.5g, and have bar stem in the middle of grain ear, produce one-level branch above it, one-level branch produces again secondary branch, three grades of branches, each grade of branch is a little code, there is a lot of seed above, nearly two or three hundred that have, during sheller unit threshing according to Traditional Rice wheat or rape combined harvester, grain ear and stalk can be caused not easily separated, paddy code not easily purifies, the high significant deficiency of grain loss rate.Add millet ripe time also have the green maturation of stalk band, feature that moisture is large, what further increase millet cleans difficulty, so the difficulty of millet mechanized harvest is very large, becomes the maximum bottleneck of millet results always.For this reason, Zeng Yeyou enterprise adheres to the combining exploring millet for many years, but effect is all undesirable, and why this namely not yet develops the main cause truly obtaining the satisfied millet combined harvester of peasant in the market.
Utility model content
The purpose of this utility model is: even if when the millet of the green maturation of a large amount of stalk bands is admitted to the process of the utility model device, also can have good rate of cleaning, little percent of loss and percentage of impurity.

Embodiment
Below in conjunction with the accompanying drawing in the utility model, the technical solution of the utility model is clearly and completely described.
As Fig. 1-8, the cleaning plant of the utility model millet combined harvester comprises the vibrating mechanism cleaned framework 51, front blower fan 52, reciprocating oscillating screen 53 and described reciprocating oscillating screen 53 is vibrated.The front upper place in framework 51 is cleaned described in described front blower fan 52 is arranged on.The back upper place in framework 51 is cleaned described in described reciprocating oscillating screen 53 is installed on.
Described front blower fan 52 adopts centrifugal blower, comprises fan shaft 521, blower fan skeleton 522, blade 523, input belt wheel 524; For controlling different wind speed needed for Different Crop, described blower fan pulley diameters is for there being level adjustable.Input belt wheel 524 comprises outer adjustment sheet 524a, middle adjustment sheet 524b, interior adjustment sheet 524c, thickness adjustment sheet 524d, changes wind speed by increasing, reducing thickness adjustment sheet.Described blower fan belt wheel 524 rotating speed regulates pad 524d by increase and decrease and has level adjustable.Because millet seed is very light, the selection by winnowing critical speed of seed and paddy handle and short cane is close.If air quantity conference makes grain blow out and cause waste, air quantity is little and make sieve block accumulation, and the structure that such speed is adjustable effectively can meet the instructions for use that millet difference results make it.Such as, low speed adapts to millet results, middling speed adapts to maturing stage millet results partially early, adapts to harvesting wheat at a high speed.
Consider that first time fails effectively to remove for the capes code do not purified when cleaning, then above-mentioned cleaning plant also comprises secondary rethreshing device, and auxiliary cleaning plant carries out threshing again, then described secondary rethreshing device 57 be arranged on described in clean the back lower place of framework 51.
This cleaning plant also comprises device 56 of delivering grain, and cleans the front lower place of framework 51 described in being arranged on.
Described reciprocating oscillating screen 53 comprise screen frame 531, screen frame seam 532, upper wire gauze sieve 533, lower wire gauze sieve 534, by original text plate 535; The top of screen frame 531 is bolted on after described screen frame seam 532 and upper wire gauze sieve 533 combine, lower wire gauze sieve 534 is bolted on the bottom of screen frame 531, be arranged on screen frame 531 Internal back end by original text plate 535, it exceeds screen frame 531 afterbody back side panel 531a topmost; The described front upper place by original text plate 535 is also fixed with width with by original text plate 535, height 30mm-50mm, sweptback plate washer 5351, and described inclination angle is that the angle of baffle plate self flanging upper back and vibratory sieve plane is 40 degree-50 and spends; Fall into the threshing again of secondary rethreshing device to tackle the capes code not yet purified further, the angle of self flanging of described baffle plate also becomes 130 degree of-155 degree.On reciprocating oscillating screen, sieve is short, is convenient to spill by original text plate, makes the paddy code not yet purified enter secondary de-threshing more again, to reduce cleaning loss.
For stoping paddy code shell to leak down, the mesh center specification of the upper wire gauze sieve 533 of described reciprocating oscillating screen 53 should be 12mm
12mm-14mm
14mm.For stoping capes code shell to leak down to reduce percentage of impurity, the mesh center specification of lower wire gauze sieve 534 is less than or equal to 6.3mm
6.3mm; According to punching steel plate sieve, then aperture should be less than 7mm.
The screen frame 531 of described reciprocating oscillating screen 53 two outside rear end be also provided with the side wing 531b of 30 degree of-50 degree that turn forward can installing moccasin, side wing 531b is provided with the moccasin can be close to sidewall and can not rubbed because of reciprocating motion again, its objective is the seed stopping and screw feeder of delivering grain below reciprocating oscillating screen 53 is blown up, reduce cleaning loss.
The utility model cleaning and sorting system comprises above-mentioned cleaning plant, and controls the controller of described cleaning plant operation.Described controller, in order to control described vibrating mechanism, makes described vibrating mechanism operate reciprocating oscillating screen 53 vibration screening cereal.Described controller can also control front rotation speed of fan, is effective conditioning agent air quantity and wind speed, and adapt to the instructions for use of the different water content in harvest of millet, Design of Rotation is about 1600r/min.
The utility model millet combined harvester, comprises above-mentioned cleaning plant, sheller unit, header or pick-up bench etc.
The above; be only the utility model patent preferably embodiment; but the protection domain of the utility model patent is not limited thereto; anyly be familiar with those skilled in the art in the technical scope of the utility model patent diselosesll; the change that can expect easily or replacement, within the protection domain that all should be encompassed in the utility model patent.
