Description
The utility model relates to various crop seeds such as a kind of paddy rice, wheat, vegetables and herbage and cleans the agricultural tool of classification.
Traditional purification of seeds grader mainly utilizes between seed and the difference of the physics-mechanical property between seed and the impurity, as size, proportion, mass of 1000 kernel and the surface roughness etc. of appearance and size, carries out selected classification by selection by winnowing and screening.But the seed that physics-mechanical characteristic is preferable might not be the superior of biological characteristics.For example the mass of 1000 kernel of seed also not exclusively is linear correlation with its germination percentage and germinating energy.
Physiology of seed studies show that, seed membrane resistance and its electrology characteristics such as medium dielectric constant are relevant with its biological characteristics-vitality.The seed that vitality is strong, its film resistance is big, electrical conductivity is little, is difficult for losing electronics, and Coulomb force suffered in electric field is little; On the contrary, the seed that vitality is weak, Coulomb force suffered in electric field is big.And because of the seed vitality difference, the inclusion chemical property is also different.So medium dielectric constant also different.The seed dielectric constant that vigor is high is little, is difficult for polarizedly, and polarization force is little.The seed dielectric constant that vigor is low is big and easily polarized, and polarization force is big.These differences make the seed of different germplasms, in electric field because the movement locus difference, thereby can realize classification by the size of vitality.

More representational electric power grader is according to classification principle, can be divided into dielectric cleaning, corona-type and electrostatic three kinds." the dielectric cleaning electric power grader " that the former Soviet Union at first develops in Moscow mainly utilizes the dielectric constant difference of seed, carries out classification with producing polarization force (absorption affinity) size between the cylinder that has electrode." the corona-type electric power grader " of U.S. Kapp pine company development mainly utilizes between seed the electrical conductivity difference in size to preserve electric charge ability difference, and it is also different and realize classification to form the Coulomb force in electric field.Electrostatic electric power grader had both utilized interseminal electrical conductivity, and same polarization power again is correlated with and is realized classification.
Since electric power grader classification principle be according to seed with Coulomb force that is produced between electrode and polarization force, but the electric weight that can be with because of seed is very little, so power is also very faint, to the bigger foreign material such as crop cane earth piece stone of proportion easy-clear not; With the similar weed seed of seed electricity rerum natura and some foreign material also easy-clear not, influence the cleanliness of seed.So main grading that only rises of electric power grader.
Electrostatic grader is as adopting metal plate as high-field electrode, and the dust in the material, pointed or shaft-like little foreign material such as wild oat seed etc. easily are adsorbed on and produce electric discharge phenomena on the battery lead plate, influence grading effect, and particulate dirt is also polluted working environment.For overcoming above-mentioned shortcoming, often adopt material to clean through cleaner-grader earlier both at home and abroad, carry out the electric power classification again.
After the classification of electric power grader, how Material collecting box for harvesting can effectively be separated and collection is a key of success by the movement locus of vitality, also is the major parameter of Material collecting box for harvesting design, all by rule of thumb, does not also have good solution both at home and abroad.
The purpose of this utility model is exactly in order to address the above problem, and a kind of purification of seeds precision height, grading effect is good, seed collection is desirable combined type seed static cleaner-grader are provided.
