Description
Technical field
The present invention relates to agricultural mechanical field more particularly to a kind of vibration sieve type seed crops based on positive/negative-pressure airflow field
Cleaning plant.
Background technique
Seed crop majority is planted in Hills and extremely frigid zones, mainly have millet, broom corn millet, sorghum, rape, flax,
Clover etc., common feature are that partial size and mass of 1000 kernel are smaller, but the physical characteristics such as shape, mobility, frictional behavior difference compared with
Greatly.Wherein, millet is the conventional crop of China, is widely used in edible coarse cereals, makes wine, the fields such as vinegar processed, contained by
Vitamin B1 occupies first of cereal crops, has high nutritive value, and the cultivated area whole world of China millet is ranked the first.China
Or 30% or so of Rape-seed production big country, area and the world total yield Jun Zhan, rapeseed oil are also the first self-produced big edible plant of China
Object oil.
Existing seed crop cleaning plant can be roughly divided into two types by cleaning principle, and one kind is the air according to cereal
Dynamic characteristics is cleaned, and air-flowing type, aspirated-air type cleaning plant are broadly divided into；Another kind of carried out using air-flow and sieve cooperation
It cleans, currently, at home and abroad in grain combine, it is the most extensive that the second class cleaning principle, that is, Winnowing type cleans utilization, this
The advantages that kind cleaning plant is adaptable preferably, cleaning efficiency is higher.The seed crop harvest in China is cleaned in operation, mainly
Based on other crops combined harvesters such as wheat, improvement appropriate is carried out, cleaning for seed crop is directly used in
Operation, but the Biological characteristics of the just de- rear material of seed crop clean mechanization to it and have apparent restricted influence, and seed
Each ingredient floatation characteristic difference of material is not significant after grain crop is just de-, leads to the cleaning efficiency of existing seed crop cleaning plant
Lower, the percentage of impurity after cleaning is higher, and can make it is miscellaneous it is remaining in be mingled with seed, cause entrainment loss and lead to the waste of seed.
Summary of the invention
To solve the problem of that existing seed crop cleaning plant cleaning efficiency is lower and be easy to cause entrainment loss, this
Invention provides a kind of vibration sieve type seed crop cleaning plant based on positive/negative-pressure airflow field.
