1987年,我场引进了两种日产水稻插秧机,即MP460型三菱插秧机和YP450C型洋马插秧机。通过我场的使用,认为这两种机型是比较理想的,适应山区、半山区和中小地块的机械插秧。一、结构特点这两种插秧机都是机动手扶式,适应于水稻中小苗带土移栽。发动机为空冷4冲程汽油发动机,采用电子打火;插秧机采用曲柄摆杆控制秧爪的运 In 1987, I introduced two kinds of Nissan rice transplanter, that is, MP460 Mitsubishi transplanter and YP450C Yanmar transplanter. Through the use of my field, I think these two models are ideal for the mechanical planting of mountainous, semi-mountainous areas and small and medium-sized plots. First, the structural characteristics of these two transplanter are mobile walk-in, adapted to small and medium-sized paddy soil transplanting. The engine is air-cooled 4-stroke gasoline engine, the use of electronic ignition; transplanter controlled by crank swinging lever seedlings
