法国 Kuhn 农机公司研制的 Kuhnflex型搂草机,获得了美国《I&T》设计竞赛二等奖。该机不用金属搂齿接触地面,可避免金属另件混入牧草中而损坏饲料收获机、压捆机、或伤害牲畜。这种搂草机的搂集作用是通过4个驱动滚筒来完成的,每个滚筒上均包有表面带肋条、周边有切口的聚氨基甲酸乙酯橡胶护罩;作物从横向通过滚筒的前端面,形成均 The Kuhnflex rake, developed by France’s Kuhn AG, won the second prize in the I & T design competition in the United States. The machine does not touch the ground with metal teeth, to avoid the other pieces of metal mixed into the grass to damage feed harvesters, balers, or injury to livestock. The raking action of the rake is accomplished by four drive rollers, each having a ribbed, peripherally cut, polyurethane rubber boot on each of the rollers; the crop passes laterally through the front end of the drum Surface, forming both
