自动调平喷杆式喷药机设计与试验研究

针对耕地存在缓坡起伏及不同农作物具有不同的植株高度的特点,设计一套能够自由调节喷杆高度的喷杆式喷药机。该机喷杆始终保持与地面平行,使喷药机在田间工作时能够通过液压系统进行自由提升,且在田间工作时可利用机械部件完成喷杆的调平工作。系统利用动滑轮和液压系统完成喷杆的提升,利用弹簧和阻尼器完成喷杆的机械调平工作。该喷药机对提高农药的利用率、降低农作物生产成本都具有积极的推动作用。

Design and Experimental Research on Automatic Levelling Boom Sprayer

For the characters of undulating gentle slope of arable land and the different height of different crops, we de-sign this boom sprayer.The spray bar could remain parallel to the ground.The boom sprayer could lift freely within the al-lowable range through the hydraulic system.The boom sprayer also could complete the leveling work in the field.The spray bar is lifted by the hydraulic system and movable block.The spring and balancing dampers are used to complete the mechanical leveling work of spray bar.The boom sprayer plays a positive role in Improving the utilization of pesticides and reducing crop production costs.
