微耕机毛病发作的缘由及扫除办法
时间:2014-12-20 来源:微耕机 作者:管理员

 

     1.微耕机负荷过大。缘由:耕深过度,土壤粘重、过硬形成。扫除:可减少深耕,降低机组行进速度和犁刀的转速。
 
  2.微耕机工作时跳动。缘由:土壤坚硬或刀片装置不正确。扫除:可降低机组行进速度和犁刀转速,并正确装置刀片。
 
  3.微耕机连续抛出大土块。缘由:刀片弯曲变形,刀片折断、丧失或严重磨损。扫除:可矫正或改换刀片。
 
  4.旋耕后的空中起伏不平。缘由:机组行进速度与刀轴转速配合不当。扫除:可恰当调整二者之间的速度。
 
  5.犁刀变速箱有杂声。缘由:装置时有异物落入,或由于轴承、齿轮牙齿损坏。扫除:需设法取出异物或改换轴承或齿轮。
 
  6.微耕机工作时有金属敲击声。缘由:传动链条过松后与传动厢体相碰擦;犁刀轴两边刀片、左支臂或传动箱体变形后互相碰击;或刀片固定螺钉松脱惹起。扫除:可检查调整传动链条张紧度,矫正或改换严重变形零件,拧紧松脱螺钉。
 
  7.微耕机犁刀轴转不动。缘由:齿轮或轴承咬死;左支臂或传动箱体变形犁刀轴弯曲变形;传动链条折断或犁刀轴缠草堵泥严重。扫除:可矫正、修复或改换严重变形、损坏零件,肃清缠草积泥。
