Accompanying drawing explanation
Fig. 1 is the structural representation of utility model works platform.
Detailed description of the invention
As shown in Figure 1, a kind of specific gravity type seed grader, be mainly used in cleaning corn seed, comprise workbench, described workbench is divided into heavy material district 11, middle material district 21 and light material district 31 and is provided with corresponding heavy material outlet 12, middle material outlet 22 and light material outlet, and workbench is respectively equipped with distributing damper 4 between heavy material outlet 12 and middle material outlet 22, between middle material outlet 22 and light material outlet 32.When seed-cleaning apparatus works, seed enters from workbench upper feeding region 10, and the full corn seed of high-quality shifts to heavy material district 11 gradually, and the seed of mean quality shifts to middle material district 21 gradually, and seed inferior shifts to light material district 31 gradually.The seed of different quality splits in the exit near each material by distributing damper 4, avoids mutually mixing between the seed of different quality.
The sidewall of each distributing damper 4 all has groove, is equipped with material scraper in groove, material scraper comprises scrapes tablet 5; Scrape the stiff end 6 of tablet 5 near groove one end close to material outlet.When staff uses, once have packing phenomenon to occur near discovery material outlet, material scraper can be started, motor drivening rod mechanism makes axis of rotation, thus scrape tablet 5 and be repeatedly rotated away from groove and get back to groove, then continue the material scraper be deposited near material outlet to enter material outlet, do not need to reduce inlet amount, solve solid accumulation problem simply and effectively, thus improve efficiency and the effect of wash seeds.Due to the existence of distributing damper 4, the scraper process of regional keeps independence, seed will be mixed because of scraper process.Because the length of corn seed generally can not more than 0.5cm, therefore the lower end of scraping tablet 5 is arranged on above workbench and apart from the vertical range of workbench and is not less than 1cm place, can make like this to scrape in the scraper process of tablet 5 when leaving groove and only scrape because seed piles up and be in upper layer seed, simultaneously get back in the process of groove scraping tablet 5, because upper layer seed is blown off, the stop of original upper layer seed can not be subject to.And there is certain gap owing to scraping bottom tablet 5 and between workbench, both the stop of bottom seed can not be subject to, also pile up due to seed and need the regular hour, the seed followed up below also has little time to accumulate and forms new upper layer seed, thus can continue the process of carrying out scraper repeatedly.In the present embodiment, the vertical range of preferably scraping the lower end distance workbench of tablet 5 is 1.2cm.
As a kind of preferred embodiment of the present utility model, the distributing damper 4 of the present embodiment is parallel to each other, like this close to heavy material district 11, middle material district 21 and light material district 31 when meeting work close to the boundary situation between outlet time domain, scrape the distance be shorter in length than between distributing damper 4 of tablet 5 simultaneously, the layering of different specific weight storeroom can not be interfered with when material scraper is started, and just can make to scrape tablet 5 normally carrys out back rotation like this, otherwise its rotation process can be subject to the stop of another block distributing damper 4.In addition, the height scraping tablet 5 is not more than the half of distributing damper 4 height, effectively can prevent material from too highly crossing the mixing that distributing damper 4 causes zones of different seed being scraped to pile up when tablet 5 promotes, further ensure the effect of cleaning.
For the maximum anglec of rotation of scraping tablet 5, the present embodiment preferably 120 degree, effect is better, and those skilled in the art also according to the working condition of reality, can adjust in the scope of 90-135 degree.This angle is unsuitable too small, otherwise the efficiency of scraper reduces; Also unsuitable excessive, otherwise be dissolved in and seed is scraped distributing damper 4 place pile up, serve opposite effect.
