Design and testing of automatic downpipe equipment for deep grain piles

Abstract China is a large grain storage country, and at this stage, the effective capacity of country has exceeded 900 million tonnes. Grain subject to localized high temperatures, pests, other abnormalities during storage. Therefore, regular quality checks need be carried out on grain, cuttings are first step in carrying checks. The current domestic cutting equipment suffers from low efficiency manual labor intensity, so develop new imminent. In response problems with equipment, work developed deep pile automatic down tube which driven by compressed air capable completing within ten-meter depth range silos. Compared traditional greatly improves samples, reduces provides ideas for development automation broad market.
