国外微耕机的发展状况
时间:2011-11-11 来源:本站 作者:管理员

国外小型微耕机械发展较早,目前主要以日本、韩国、意大利、法国和美国等国家的产品为代表,配套动务为1.47-5.88kW汽油机或柴油机,普遍采用2.2-5.1kW动力。欧洲国家的产品以园艺作业为主,主要功能有旋耕、剪草、清雪、粉碎、短距离运输等,而亚洲国家的产品则以农业作业为主,如日本、韩国和我国台湾的产品。日本机型兼顾水旱地两用,可进行翻地、旋耕、起垄、铺膜、开沟、播种及水田平整等;韩国和台湾机型则以旱地(果园、菜地、温室大棚及其他小块地)作业为主,韩国机型的显著特点体现在多功能方面,其典型代表机型为亚细亚多功能管理机。该机除了可进行耕整地、栽植、开沟、起垄、铺膜、中耕锄草、施肥培土、抽水、喷药及短途运输作业外,还可进行粉碎、稻麦收割、根茎收获等20多项作业。


欧洲微耕机机型的发动机动力轴多向后输出,通过一对伞齿轮与轮(刀)轴齿轮箱联接,并通过传动轴驱动剪草机、清雪机和粉碎机等园艺机具,这时扶手转到发动机前面,其优点是整机结构紧凑,但驱动一些农用机具时传动不太方便,工作部件安装位置不好布置。日本、韩国和我国台湾机型的发动机输出轴向一侧布置,通过两根胶带与轮(刀)轴齿轮箱联接,并利用胶带或链条驱动各种作业机具。台湾机型结构相对简单,外观也较日本和韩国产品有些差异。亚洲3.7kW以上机型在旱地深旋作业时多采用搅刀,这种刀的特点是松土性能好,旋土深,碰到石头或硬物能避让,不会损坏刀具。但其缺点一是碎土性能稍差(在一定转速和前进速度下方可达到碎土性能要求),二是功率消耗较大,所以动力小的机型不宜采用这种刀型。


国外微耕机机型大部分都具有以下主要特点:小巧、灵活,外形美观,操作方便(操向手把能旋转并可调节高低);采用排放量低的小型汽油机或柴油机为动力;可方便、简单、快速地更换多种工作部件,完成多项作业
