Description

There are the method for concentrating, iron mixture and seed cleaning equipment of crack cotton seeds

Technical field

It is a kind of method for concentrating for having crack cotton seeds, iron mixture the present invention relates to seed cleaning technical field With seed cleaning equipment.

Background technique

Cotton, due to mechanical and livestock operation behavior, inevitably results in outer in harvest, processing and storage and transport process Wound, especially mechanical damage, this will be so that will appear the problems such as including crack cottonseed and broken cottonseed cottonseed in seed, these Problem cottonseed is generally up to 8% or so, up to 15% or so, wherein the crack cottonseed of " splitting without broken " accounts for about the 70% of problem cottonseed, Remaining is the broken cottonseed of " split and break "；Due to thering is the idiosome part of crack cottonseed and kind skin to be subjected to destruction, can not normally send out Bud and emergence, this can significantly reduce percentage of seedgermination and cotton field survival rate of seedlings.

Inventor to seed cleaning system of processing research shows that: the gravity preparation and wind that must match as Modern Seed dressing process Screening, which removes, can remove the not chitting piece such as special-shaped seed that is overweight, kicking the beam, empty not plump seed, yellow seed, moreover it is possible to successfully remove broken cottonseed, but There is crack seed that cannot remove as normal mature seed shape.Though color sorting technology is acknowledged as cotton seeds essence in recent years One break-through skill of choosing, but shape can not be removed have crack seed as normal mature seed.

According to statistics, it is obtained using the selected processing technology of advanced cotton seeds of existing " gravity preparation+pneumatic jig choosing+color sorting " Cottonseed, percentage of seedgermination, which is difficult to stablize, keeps 90% or more, such as only has " gravity preparation+pneumatic jig choosing ", and the conventional beneficiation without color sorting Technique, germination percentage is lower, and only 80% or so.Further investigation shows: related crack seed cleaning compares successful story It is: Britain carat text and Nicholas Engineering Co., Ltd (Craven and Nicholas Engineering Ltd) research and development Carat text pin type classifier (Cravnic needle sorting machines), its working principle is that: seed feed warp Elevator feeding hopper is crossed, then even into the roller that thinner stainless pin is housed, then by the roller with slower speed Uniform rotation, drives material rotation, and the stainless pin in roller is selectively pierced into seed crack and small holes caused by worms due to having Function, and top, the seed that finally stainless pin is pierced by the nylon bristle Jing Guo helical rotation are carried it into roller rotation Brush is lower and is discharged, so that realizing has crack, has the separation of small holes caused by worms seed, although it has for removing the nut fruits such as beans, American pistachios Lacerated wound seed is relatively more successful, but in the selected upper reported success without using the machinery of cotton seeds.In addition, the great Xiang of Jiangsu Province, China Machinery Manufacturing Co., Ltd. and De Lixin General Devices Co., Ltd. of Liyang City of Jiangsu Province once developed to remove crack cotton The pin type refiner of flower seed, product cotton seeds process when also once used, but due to its exploitation maintenance of machine at This height, critical component, especially thinner stainless pin serious wear, replacement is difficult, along with its stability is bad, Yi Jisheng It is lower to produce efficiency, is now also eliminated.Further analysis shows: the beans of crannied cotton seeds and cracking, American pistachios etc. are hard Fruit is compared, and lacerated wound has very big difference, is presented as that cotton seeds crack is smaller, and depth is more shallow, and Size of Crack, shape difference Larger, on the one hand because its crack is overall smaller or even unobvious, the stainless pin needed should be thinner, because thinner stainless Steel needle is easier to be worn or fracture and influences selected effect.On the other hand stainless because Size of Crack and shape are seriously inconsistent Steel needle model can not accomplish with the crack seed size that occurs at random and shape organic linking, and then lead to considerable have crack Cotton seeds cannot be rejected effectively, and thus clear pin type seed choosing method is not applicable has crack cotton seeds selected.

Seed magnetic separator (MAGNETIC SEED CLEANER) at home and abroad has many reports, but the cereal seed that focuses mostly on It cleans, forms a closed strong magnetic field particular by seed magnetic separator or magnetic separation stick, recycle suitable speed at this Material (cereal seed) is shed in magnetic field, the difference for the magnetic attraction power that because of cereal seed and wherein metal and soil block are subject to, And keep cereal seed different from the distance that different sundries therein are shed, so that it be separated with cereal seed, go native effect Fruit is very good, goes native rate up to 99% or more, is typical seed refining apparatus, it is clear that the magnetic separator or magnetic separation stick of cereal seed It can not be selected to there is crack cotton seeds to carry out.

Research shows that: have crack cotton seeds be always perplex factor that World cotton production and planting benefit improve it One.Expert generally believes: if can have crack cotton seeds by mechanical effectively reject, not only saving manpower and financial resources, moreover it is possible to bright Aobvious to improve output of cotton and benefit, along with cotton planting scale in the whole world is big, thus exploitation has crack cotton seeds refiner Tool has a very big market prospects, but due to developing the product there are biggish technical difficulty, up to now domestic and international Seed enterprises Without successfully developing corresponding picking equipment for crannied cotton seeds.These enterprises include emerging hundred benefit of wheat (Cimbria) combine cereal Co., Ltd, Wai Si Troup Co., Ltd of Denmark (Westrup A/S), Germany Pei Teku This joint-stock company (PETKUS Technologie GmbH), the U.S. Carter Day International, Inc., Turkey The world-class seeds company and Nanjing of China farming & stockbreeding machinery factory such as AKYUREK Kardesler Ltd company, Jiuquan Austria are triumphant Seed Mechanology Inc., Shijiazhuang Sen Mai International Agriculture Mechanology Inc., Sanli Corp Fine Selection Machinery Co., Ltd., Shijiazhuang, Shijiazhuang Ju Lite Machinery Co., Ltd., Hebei resultant force reach grain selecting machinery Science and Technology Ltd., Hebei timely snow grain selecting machinery system Make the domestic well-known seeds company such as Co., Ltd, Hebei Mao Heng Machinery Co., Ltd..

Due to there is no breakthrough for the selecting technique for being mixed with crack cotton seeds, so that the cotton master that the world is all Producing region percentage of seedgermination is almost between 80%-85%.In developed country, using the sowing seeds technology in " one, a cave ", Precision drilling cotton field survival rate of seedlings generally can be only sustained at 74% or so, and significantly cause the underproduction.And in developing country, including in The lower country of human cost including state adopts more to have solved the problems, such as that crack cotton seeds bring cotton field survival rate of seedlings is low With the seeding method in " more an of cave ", crack cotton seeds thus can be effectively solved to the adverse effect of cotton field survival rate of seedlings, but this Kind seeding method, not only sowing quantity is big, and seed is caused to waste, and also will increase the cotton field final singling workload in later period, is a kind of typical case " wasting man power and money " act, with the economic development of cotton planting state, more and more cotton main producing regions, cotton field recruitment cost is not It is disconnected to increase, even occur the phenomenon that " recruitment is waste " sometimes, to reduce cotton field recruitment cost, reduce to manpower operation it is excessive according to Rely, in a manner of the precision drilling that more and more cotton fields have to select to use by the U.S. " one, a cave " for representative.To avoid Because crack seed causes precision drilling cotton field survival rate of seedlings low and per unit area yield reduction, the advantage for often utilizing the price of labour power cheap, Sowing seeds technology in popularization and application " one, a cave ", it is main using by manually choose examine have the method for crack cotton seeds come It solves, though this method effect is more apparent, its low efficiency, time-consuming are more, and quality stability is poor and uncontrollable, as the world is each The continuous improvement of cotton region productivity and living standard, eliminating and manually choosing detecting method is trend of the times.
