Description

Grain cleaner

The utility model relates to a kind of processing equipment of agricultural results product, is a kind of grain cleaner specifically.

Before the utility model design is finished.Cereal, wheat for example, barley, rice, millets etc. after the maturation, generally adopt combine to gather in.Combine after cutting off, is sent into the sheller unit of combine with the cereal of maturation, and will mix then has the cereal of straw and cavings to separate, and will mix cereal again and send in the truck of going together with combine.Cereal after the threshing separates not thoroughly with straw with cavings, still mixing in the cereal has straw, cavings, Gu Mang and earth and sand grains etc., also includes the cereal kernel of not removing cavings.Remove the foreign material that mix in the cereal, pay a lot of work, people generally will use wooden winnowing spade one shovel one shovel ground " to winnow " with this cereal one time one " dry in the air " everywhere then, by the strength of wind, with cereal with mix separately in the seed of wherein stalk, cavings and band cavings.This usefulness during manually with the working expenditure of grain cleaning, effort, efficient is not high.

The purpose of this utility model just is to overcome manually cleans time-consuming, the effort of cereal, the defective that efficient is not high, a kind of grain cleaner is provided, roll, remove awns, the seed that will mix stalk, cavings and band cavings in the cereal is separated, and sand grains that will be wherein, earth etc. are also separated, clean selected purpose thereby reach.

The utility model is realized with following technical proposals:

Grain cleaner is by the belt device of winnowing, awner, and fan, screen cloth, assorting cylinder and elevator screeding device are formed, and power is provided by tractor.Belt is winnowed device by active roller tube, two driven roller tubes and belt are formed, initiatively the roller tube links to each other with belt with one of them driven roller tube, another driven roller tube is pressed in initiatively on the belt between the roller tube and driven roller tube, initiatively the roller tube links to each other by the winnow belt pulley of device of belt and belt, the winnow coaxial belt pulley of belt pulley and the fan pulley of fan of device of belt links to each other by belt, fan pulley links to each other by belt with the output belt pulley of tractor, awner is to have the wheel shaft of finger and the screw feeder composition coaxial with it, awner is scraped web wheel by belt and elevator and is linked to each other, fan is positioned at separator top, in the separator bottom screen cloth is arranged, assorting cylinder is a drum type, and inwall has pit, contact with the winnow active roller tube of device of belt, portion is installed with defeated grain slide plate within it.The elevator screeding device carries out transmission by sprocket wheel, and perpendicular scraper plate is arranged on chain.The size of the pit of assorting cylinder inwall and cereal kernel measure-alike.The size of the sieve aperture of screen cloth is slightly littler than the size of cereal kernel.

The utility model has following good effect:

Because the utility model is made up of the device of winnowing, awner, fan, screen cloth, assorting cylinder and elevator screeding device, power is provided by tractor.The straw that has with results, the cereal that mixes of the cereal kernel of cavings and band cavings is deposited in the threshing ground, the elevator screeding device of the utility model grain cleaner is rotated around the elevator scraper shaft, insertion cereal heap, mix cereal and will constantly be transported to the belt device of winnowing, through being pressed in rolling of driven roller tube on the belt between the skin beam barrel and driven roller tube initiatively, stone roller removes the outer cavings of cereal kernel, the crushing soil block, mixing cereal will be raised in removing the awns device by throwing, in removing the awns device, cereal is removed awns finger bump, and Gu Mang is separated from cereal with cavings, is stirred out by the screw feeder coaxial with it then, screw feeder stirs out mixes wind that cereal sent here by fan with cavings, Gu Mang blows out, heavier cereal and sand grains, finger stone then falls, through the screen cloth screening, less than the sand grains of cereal, finger stone then is sieved into underground.Assorting cylinder is in rotary course, the cereal kernel that slips into assorting cylinder by defeated grain slide plate falls in the pit on the inwall of assorting cylinder, forwarded to the top by drive, since the effect of gravity, the slide plate above falling into, flow out by tilting slide plate, pack, its cereal greater than the band chaff of cereal size reaches the finger stone of some greatly, and the grains of sand then can not enter the pit of inwall, be in the bottom, thereby cereal, sand grains and the finger stone of these band chaffs separated with cereal.Like this, through rolling of roller tube, the bump of the finger of awner removes awns, the cereal of band chaff can be removed chaff, with the big small clod crushing of sneaking in the cereal, again through fan, screening, assorting cylinder can be divided into the cereal that mixes chaff, dust, sand grains, bigger stone and several parts of clean cereal kernel, discharge from outlet separately respectively, reach the purpose of thoroughly cleaning.

Below in conjunction with accompanying drawing, structure of the present utility model is described in further detail.
