    摘要:

    針對東北一年一熟壟作區(qū)玉米根茬地免耕播種時(shí)存在根茬不易破除且易掛茬等問題,，設(shè)計(jì)了一種驅(qū)動(dòng)破茬裝置,，該裝置在3個(gè)平面內(nèi)安裝破茬刀具,，其中心與開溝器前后對齊。為確定破茬裝置的合理結(jié)構(gòu),，設(shè)計(jì)了3種軸套,，同時(shí)設(shè)計(jì)了3種刀具組合方式。在土槽上進(jìn)行了三因素三水平的正交試驗(yàn)，通過分析各因素對功率消耗和根茬切斷率2個(gè)指標(biāo)的影響,，得出較好的參考組合：機(jī)具前進(jìn)速度為0.75km/h,，刀軸旋轉(zhuǎn)速度為150r/min，刀具組合方式為ZH2,。對軸套進(jìn)行選擇的試驗(yàn)表明,，當(dāng)產(chǎn)生相同切土節(jié)距S=2cm時(shí)，軸套2的功率消耗較低,，根茬切斷率達(dá)到

    Abstract:

    92%,。 A power driven cutting mechanism of ridge-till and no-till corn planter was designed to treat rootstalk during no-till plant corn in the areas of one crop a year. Three rows blades are fitted on the axis for one ridge in this mechanism. Three kinds of spindle-harnesses and three kinds of blade-installations were designed in order to find out a most reasonable form. The soil bin experimentation showed that the mechanism has a good ability to cut corn rootstalks, when the running speed is 0.75km/h, the rotor speed is 150r/min and the blade-installation is ZH2. The experimentation for choosing spindle-harnesses showed that the second spindle harness which has better cutting ability and lower power consumption is the best choice.
