Machinery Industry Bureau of Shandong Revolutionary Committee, held from June 15 to 18, 1984 in Gaomi County, Hongqi held an identification meeting of the Hongqi 5T-450 air-flow cleaning thresher, the representatives agreed that: Gaomi County Agricultural Machinery Factory trial production of red flag 5T-450 air cleaning threshing machine small size, light weight, safe and reliable, reasonable structure, good technology, drawing convenient, easy to manufacture and maintenance. But also broke the traditional grooved roller drum and filter threshing machine frame, novel structure, in the threshing, clearance, break new ground. In addition to grain entrainment indicators in the stem, the remaining technical performance indicators, basically meet the design requirements, drawings and related technical documents basically complete and complete, to meet the production requirements, can arrange small batch production.
