由中国农机院和太原市脱粒机厂共同研制的5T-50型、5TS—50型和5TJS—50型三种小型脱粒机,于今夏麦收期间先后在河南信阳地区、河北石家庄地区和山西太原市郊区作了小麦脱粒性能试验和生产考核试验。截至7月10日止,5T—50、5TS—50型脱粒机已先成250小时生产试验。性能试验结果表明,当小麦的草谷比为1.5,籽粒含水率为14.5%,5T型及5TS型的小时生产率分别不超过1吨、1.2吨情况下,这两种机具的总损失率都不大于1.5%,破碎率低于1%,籽粒清洁度大于98%,度电生产率均在200公斤/千瓦·小时以上,达到了国家标准。
Three small threshers, 5T-50, 5TS-50 and 5TJS-50, jointly developed by China Agricultural Machinery Factory and Taiyuan Threshing Machine Factory, were successively located in Xinyang, Henan, Shijiazhuang, Hebei Province and Taiyuan, Shanxi Suburban wheat threshing performance test and production test. As of July 10, 5T-50, 5TS-50-type threshing machine has been the first 250-hour production test. The results of the performance test showed that when the ratio of grass to grain of wheat is 1.5 and the moisture content of grain is 14.5%, the hour productivity of 5T and 5TS respectively does not exceed 1 ton, and the total loss rate of these two kinds of tools is no more than 1.2 ton 1.5%, the broken rate is less than 1%, the grain cleanliness is greater than 98%, the electrical productivity is above 200 kg / kWh, reaching the national standard.
