果林开沟施肥是提高果品质量,增产、增收的重要保证。开沟作业劳动强度大,很难保证工期和作业质量,特别是人工作业劳力缺乏,费用高。迫切需要机械化来满足农业发展的需求。研制有技术含量,适用于树冠旁行走的小型四轮驱动液压开沟机有其必要性。1技术关键(1)四轮驱动、功率大、体积小、底盘低,能在靠近树干处沟式作业施肥,便于树根系吸收。(2)沟形的深度及宽度调节方便,抛土可在沟的一侧或者
Ditch ditch fertilization is to improve fruit quality, increase production, income an important guarantee. Trenching operations labor-intensive, it is difficult to ensure the duration and quality of operations, especially the lack of manual labor, high cost. There is an urgent need for mechanization to meet the needs of agricultural development. It is necessary to develop a small four-wheel drive hydraulic ditching machine with a technical content suitable for walking along a canopy. A key technology (1) four-wheel drive, power, small size, low chassis, can be near the trunk Department of fertilizers ditch operation, easy to root absorption system. (2) The depth and width of the ditch is easy to adjust and the thrown soil can be on one side of the ditch or
