40N系列大豆挠性低割装置是为减少大豆机械收获损失而设计的,是在总结我省国营农场和乡、村多年来豆收机具的改装经验的基础上,并吸收国外的先进技术,结合我国的国情而研制成功的新型大豆低割部件。 该装置有三种系列产品,其中4DNB—5.7型与北大荒—6谷物联合收获机配套,4DNE—4.2型与E512谷物联合收获机配套,40ND—4.0型与东风—5谷物联合收获机配套。 该装置是自 1981年6月至1982年12月由黑龙江省农机研究所设计,依兰收获机械厂试制,并于1983年1月通过省级科研鉴定的科研成果。同年荣获省政府科研成果二等奖。自1983年至1985年三年内已推广使用了591台,产值达174.42万元,上交税金3273万元,利润24.2万元,大豆增收了2332.8万斤,收入人民币699.84万元。1986年又推广了234台,四年合计推广825台。
40N series soybean flexible low cut device is designed to reduce the loss of soybean mechanical harvesting. Based on the experience of modification of soybean harvesting machine in our country’s state-owned farms and townships and villages over the years, the 40N series soybeans flexible low-cut device absorbs foreign advanced technologies and combines China’s national conditions and the successful development of new low-cut parts of soybeans. The device has three series of products, of which 4DNB-5.7 and North Harvest-6 grain combine harvester, 4DNE-4.2 and E512 grain combine harvester, 40ND-4.0 and DF-5 cereal combine harvester. The device is from June 1981 to December 1982 by the Heilongjiang Provincial Agricultural Machinery Institute, Yilan Harvest Machinery Plant trial production, and in January 1983 passed the provincial scientific research appraisal of scientific research. The same year won the provincial government scientific research second prize. From 1983 to 1985, 591 units have been promoted and used, with an output value of 1.7442 million yuan, taxes of 32.73 million yuan and a profit of 242,000 yuan. Soybean has increased by 23.328 million tons and its revenue has reached 6,998,400 yuan. In 1986, it was promoted to 234 units, bringing the total to 825 for four years.
