Abstract
The invention discloses a cereal screening device and relates to the field of screening and separating. The cereal screening device comprises a roughing bin and a concentrating bin. The roughing bin comprises a cylindrical outer bin fixed on a machine frame, a feeding opening formed above the outer bin, a driving device which is fixed at the end face of the outer bin and carry out transmission on a screening cylinder, the screen cylinder arranged close to one side of the driving device in the outer bin and a spiral body arranged in the screen cylinder in a sleeved mode. A cereal outlet is formed in the outer bin below the screen cylinder. The cereal outlet is provided with a small stone screening device. A large impurity outlet is formed below one side, relative to the driving device, in the outer bin. The large impurity outlet is provided with a secondary screening device. Stones with sizes larger and smaller than a screening opening can be removed.
Description
Technical field
The present invention relates to screening separation field, particularly relate to a kind of grain sieving device.
Background technology
After paddy harvesting, to the preliminary removal of impurities of cereal, to ensure grain smoothly by each processing apparatus thereafter, safe transport to be carried out, prevent equipment fault and damage, also there is the effect improving cleaning machinery and other equipment operating efficiencies simultaneously.The mode that existing grain sieving device adopts: by the friction between screen cloth and grain, filters out grain from the network interface shining net, and the impurity being greater than grain size is disallowable online in solarization.All kinds of corrupt practices creep in adopt this scheme: be difficult to clean for disposable for all impurity rejecting.Impurity inside cereal has the long fibrous impurities etc. of masonry, clod and careless bar and so on usually, and different impurity is due to its physical characteristic difference, and the mode therefore rejected is also just different.This scheme can only propose the impurity larger than grain size, and the finger stone similar with its size is just difficult to reject totally.
Summary of the invention
The invention is intended to provide one size can be greater than sieve mouth, the grain sieving device that the stone that size can be less than again sieve mouth is rejected.
Grain sieving device in this programme, comprise and roughly select storehouse and selected storehouse, roughly select storehouse and comprise the conveyor screw being fixed in frame cylindric outer storehouse, being arranged on charging aperture above outer storehouse, being fixed on screen drum that outer storehouse end face arranges near the side of drive unit drive unit, outside inside, storehouse that screen drum carries out transmission and the setting of screen drum inner sleeve, outer storehouse below screen drum is provided with grain outlet, this grain outlet is also provided with gravelstone grain screening plant, the large impurities outlet of a side-lower setting of the inner drive unit relatively in storehouse outside, large impurities outlet is provided with postsearch screening device.
Know-why of the present invention is as follows: unscreened cereal enters screen drum by charging aperture; screen drum is under the drive of drive unit; orientation is rolled; grain rolls in screen drum; sieve mouth from screen drum is entered grain outlet by the grain or the impurity that are less than screen drum sieve mouth size; in grain outlet, also have gravelstone grain screening plant, can together be rejected with cereal by the gravelstone grain of the sieve mouth of screen drum further.Conveyor screw simultaneously in screen drum also can follow screen drum to rotate, the disallowable impurity of drive moves to large impurities outlet by the conveyor screw rotated, and then enter large impurities outlet, also have postsearch screening device at large impurities outlet, the grain sieve being discharged to large impurities outlet can be elected in screen drum with large impurity.
Technique effect of the present invention is as follows: in tradition to the device large impurity screening basis adding screening handstone, screen further cereal, the cereal impurity through the screening of this device is rejected more thorough.
Further, the by-pass port that the side sidewall that gravelstone grain screening plant is included in grain outlet is arranged, the opposite side sidewall of this grain outlet arranges air blast, further size is less than screen drum to sieve young stone grain and screen away from grain, density due to stone is greater than the density of grain, therefore under blower blows, grain all enters bypass pipe, and the stone that density is larger directly falls along encouraging exports.
Further, the by-pass port that the side sidewall that postsearch screening device is included in large impurities outlet is arranged, the opposite side sidewall of this large impurities outlet arranges air blast, because real large impurity is different with grain density, under blower blows, the grain that density is large directly falls, and the little impurity of density enters bypass pipe.
Further, the side that warehouse drive unit is relative is provided with maintenance door, time device inner components breaks down, can open maintenance door, keep in repair device inside.
Further, screen drum is axially arranged with cleaning brush, can clear up the impurity be stuck on screen drum mouth and grain, prevents screen drum generation blocking.
Accompanying drawing explanation
Fig. 1 is the structural representation of grain sieving device embodiment of the present invention.
Detailed description of the invention
Below by detailed description of the invention, the present invention is further detailed explanation:
Reference numeral in Figure of description comprises: motor 1, screen drum 2, bypass pipe 3, grain outlet 4, conveyor screw 5, charging aperture 6, large impurities outlet 7, inlet scoop 9, cleaning brush 10.
Embodiment is substantially as shown in Figure 1:
The present invention includes and roughly select storehouse and selected storehouse, wherein roughly select storehouse and comprise outer storehouse, screen drum 2, conveyor screw 5 and cleaning brush 10, outer storehouse is that cylindrical shape is horizontally disposed with, screen drum 2 outside the inner right-hand member in storehouse and its coaxially roll and arrange, screen drum 2 internal fixtion conveyor screw 5, outer storehouse above screen drum 2 is provided with inlet scoop 9, be convenient to internal gas flow flowing in outer storehouse when screen drum 2 rolls, screen drum 2 upper shaft is to being provided with cleaning brush 10, be convenient to clear up and be stuck in screen drum 2 and sieve cereal in mouth and impurity, outer storehouse right-hand member fixed electrical machinery 1, this motor 1 output shaft and screen drum 2 coaxial transmission.
The upper end in the left side in storehouse is provided with charging aperture 6 outside, and this charging aperture 6 is inner for being extended to screen drum 2 by a feeding-passage.
The downside in storehouse is provided with selected storehouse outside, this selected storehouse comprises air blast, large impurities outlet 7 and grain outlet 4, outer storehouse on the downside of screen drum 2 is provided with grain outlet 4, on the left of this grain outlet 4, air blast is set, the right side of grain outlet 4 arranges bypass pipe 3, in time being screened cereal by screen drum 2 and discharge from grain outlet 4, through blower blows, the stone that density is larger directly falls, and the cereal that density is less is discharged from bypass pipe 3.Below outside on the left of storehouse is provided with large impurities outlet 7, on the right side of large impurities outlet 7, air blast is set, left side is provided with bypass pipe 3, when large impurity is discharged from large impurities outlet 7 together with partial grains one barrel, blower blows, the large impurity that density is less is discharged from bypass pipe 3, and the cereal that density is larger directly falls.
