| 摘 要： | 太行山区果园地表贫瘠、耕层土壤少、石砾多,果树生长的同时果园内野草蔓生。除草的难题不仅在于山区果园地域广袤,青壮劳动力匮乏,而且人工成本日益攀升,再加上果树株行距较小、地面崎岖不平,以及遍布各处的、大小与形状各异的石块与树枝等杂物,传统除草机械在此环境中无法运行,开发一款适应山区果园的新型除草机械迫在眉睫。以"特色农机装备研究与开发"项目为依托,开发了一款挠性除草部件离心式除草机,配备小型四轮拖拉机,具有机动灵活、除草效果好、适应多砾石果园等特点;但其高速旋转的工作部件(动刀头—特型挠性结构)不可避免地会与草间石块等异物发生碰撞,致使动刀头应力过大而崩裂。为此,对动刀头与石块撞击后的受力进行了理论分析与参数结构设计,经实地检验,该机具清除杂草0.13hm2/h左右,除草效果良好,且具有相对较长的使用寿命1-2]。

| Abstract: | The orchard grounds of Taihang mountain are barren and the arable layer soil are less but gravel more .When the fruit trees of orchards grow , the wild grasses are sprawling simultaneously .Weeding problem lies in not only the mountainous region vast , lack of younger workforce , but also labor costs increasing , the smaller of fruit plant row spac-ing , the bumpy grounds , and variable sizes and shapes of stones and branches everywhere .The fact proved that the tra-ditional weeding machines didn't work in this environment .Therefore , to develop a new weeding machine which adapt to the mountain orchard is imminent .On the based of the science and technology support projects called “research and de-velopment of characteristic agricultural machinery and equipment” in Hebei province , has developed a centrifugal wee-ding machine with flexible weeding components , which can match with small four-wheel tractor .Its advantages are flexi-ble , good weeding effect , good adaptability to more gravel orchard etc .While because the working parts of high speed ro-tation will inevitably collide with rocks in the grass , the dynamic stress may be too great so that split the cutting tools . This paper theoretically analyzed the dynamic stress of cutting head after impact with the stones and designed the structure parameters .In the field test , the machine can weed about 2 Mu of weeds per hour , weeding effect is good , the machine has a relatively long life 1-2 ] . |
