国内小马力(3～12)挂机、挂桨近年来发展较快.由于变螺距挂机、挂桨,较之定螺距挂机、挂桨具有更好的适应性、制动性,所以在农(渔)业的水上运输中,更为广泛地得到发展和应用.但是,国内已有的各种机型普遍存在着操纵机构设计不合理,工作不够安全可靠等缺点.为此我们研制了7GB-3 Domestic hanging horsepower (3 ~ 12) hanging, hanging paddle developed rapidly in recent years due to variable pitch hanging, hanging paddle, compared with the fixed pitch hook, hanging paddle has better adaptability, braking, so in agriculture ) Industry in the water transport, more widely developed and applied.However, all kinds of domestic models are generally existing control mechanism design is not reasonable, safe and reliable work shortcomings, etc. For this we have developed a 7GB-3
