Description

A kind of wheat combination sieve
Technical field
The present invention relates to a kind of filter for grain, more particularly to a kind of wheat combination sieve.
Background technology
Due in little dung heap containing the different impurity of quantity so that its flour extraction difference is larger, and produced flour is apparent and interior Also larger in quality differential, wheat puts in storage containing worm living, causes insect pest in storehouse, loses raw grain, because there is above-mentioned reason so that There is difference in price in wheat.
When wheat is purchased, prevent that illegal grain dealer converts vacation, lead corporate reputation into a trap, affect product yield and quality, in time more Fill a vacancy sunken, lower risk, remove big impurity, such as straw class in wheat to greatest extent;Middle impurity, such as straw pipe nipple;, small impurities, Such as silt dirt and grass-seed, insect etc., isolate that the big and full wheat of seed, seed be little or flat wheat, it is ensured that wheat purity, improve Economic benefit and ecological benefits.Need to screen wheat, existing screen equipment yield is low, efficiency is low, classification is few, it is impossible to spirit It is living to use.
The content of the invention
The invention aims to the wheat screen equipment yield for solving to be used at this stage is low, efficiency is low, classification is few, The shortcomings of flexibly can not using, and a kind of wheat combination sieve for proposing.
To achieve these goals, present invention employs following technical scheme:
