为了解决我国农田水利的排灌渠道的淤泥清理问题,中国农机院和河南省驻马店市农机厂根据机械工业部下达的课题任务,研制成功了775QY-0.2型液压挖掘式清淤机。该机是在原775W-0.25型液压挖掘机的基础上改进设计的,主要是为了满足渠道清淤作业的需要。机具主要由反铲挖掘斗、清淤铲斗、伸缩斗柄、动臂、液压系统、回转机构、悬架、支脚、变速箱、操作台等组成。该机有如下特点: 1.设有伸缩斗柄,其变幅范围0～900毫米,最大挖掘半径8米。单侧清淤,可在上口宽不大于7米的沟渠上作业;两侧清淤,能在上口宽不大于14米
In order to solve the problem of silt disposal in irrigation and drainage channels of farmland irrigation in China, Agricultural Machinery Research Institute of China Farm and Zhumadian City, Henan Province successfully developed the 775QY-0.2 hydraulic excavation dredger according to the tasks assigned by Ministry of Machinery Industry. The machine is based on the original 775W-0.25 hydraulic excavator to improve the design, mainly to meet the needs of channel dredging operations. Mainly by the backhoe dig bucket, dredging bucket, telescopic handle, boom, hydraulic system, slewing gear, suspension, feet, gearbox, console and other components. The machine has the following characteristics: 1. Has a telescopic handle, the amplitude range of 0 to 900 mm, the maximum excavation radius of 8 meters. Dredging on one side can work on ditches with a width of not more than 7m; dredging on both sides can be not more than 14m in width
