Description
Technical field
The present invention relates to agriculture seed selecting technique, be specifically related to a kind of seed gravity concentrator.
Background technology
Seed could be put in storage through screening usually.The screening of seed is divided into primary election and selected, what primary election adopted usually is first clear, is used for removing the bigger material in seed and light foreign material, selected employing be refiner, be that seed is carried out sorting by density and size further.
The primary structure of existing seed purifier comprise feed hopper, be communicated with feed hopper seed is sucked Classification Desk and the Pneumatic System of wind-force is provided, is used for the Classification Desk that seed is carried out sorting by density and size and the receiving hopper be communicated with Classification Desk for Classification Desk.The main weak point that above-mentioned seed purifier exists is: 1. seed preliminary removal of impurities and classification is selected adopts two machines respectively, cost is high, and although seed can remove certain bigger material and light impurity after primary election usually, but be still mixed with foreign material in seed, and existing refiner did not arrange corresponding removal of impurities structure before classification and sorting, the seed sub-elected is caused still to be mixed with foreign material; 2., during work, seed directly enters Classification Desk by conveying pipeline, and in order to pass through pneumatic seed-transportation, certain air-flow can be passed in conveying pipeline, this part air-flow enters Classification Desk easily via the mouth of pipe of conveying pipeline, and cannot ensure the negative pressure state in Classification Desk, and affects separating effect; 3. usually only arrange one deck screen cloth, Long-Time Service in Classification Desk, screen cloth face is yielding, and wind speed in Classification Desk is uneven, also can affect the effect of sorting.
Summary of the invention
The invention is intended to provide a kind of seed gravity concentrator that can carry out elementary removal of impurities to seed.
Seed gravity concentrator in this programme, seed gravity concentrator, is characterized in that, comprises bracing frame and the brace table with bracing frame one, the side direction of brace table is respectively equipped with control cabinet, feed hopper and Pneumatic System, and the top of brace table is provided with Classification Desk and seed reception bucket;
