东风—5型联合收割机,已远不能适应农业高产的要求,在正常条件下的喂入量只能达到3～4公斤/秒,就显得效率低、损失大、易堵塞。另一方面,在我国小麦主要产区华北、华中等地(水浇地冬小麦产量达500～800斤/亩)逐渐推广使用该机。对该机提出适应高产的要求日益迫切。四平联合收割机厂根据用户的要求,在东风—5型联合收割机的基础上,进行彻底的改进设计。样机已经过两轮试制,今年进行第三轮样机试制。改进设计后的机型,整机生产率要提高25～30%,即喂入
DF-5 combine harvester has been far unable to meet the requirements of high-yielding agriculture, under normal conditions, the amount of feed can only reach 3 to 4 kg / s, it appears inefficient, loss, easy to plug. On the other hand, the main wheat-producing areas in North China, Central China and other places (irrigated fields yield 500 ~ 800 kg / mu) gradually promote the use of the aircraft. The machine made to meet the requirements of high yielding increasingly urgent. Siping Combine Harvester Factory according to the requirements of users, on the basis of DF-5 combine harvester, to thoroughly improve the design. Prototype has been trial two rounds, this year for the third round of prototype trial. Improve the design of the model, the whole machine productivity should be increased by 25 to 30%, that is fed
