小型联合收割机一般以8.8～18.4千瓦(12～25马力)小四轮拖拉机为动力,集收割、脱粒、清选为一体。受经济水平制约,大中型联合收割机的普及还只能是一个遥远的目标。因此“小联合”的发展便备受关注,发展也很迅猛,仅仅几年时间,全国就出现了100余家生产企业。同时,围绕着“小联合”的产生和发展,引起了科研、生产和使用各界的激烈争议。
Small combine harvester generally with 8.8 ~ 18.4 kilowatts (12 ~ 25 horsepower) small four-wheel tractors as the driving force, harvesting, threshing, cleaning as one. Constrained by the economic level, the popularity of large and medium-sized combine harvesters can only be a distant goal. Therefore, the development of “small joint” has drawn much attention and developed rapidly. In just a few years, more than 100 manufacturing enterprises nationwide appeared. At the same time, the emergence and development of “small coalitions” have caused heated debates in all fields of scientific research, production and use.
