3WF-12型超宽幅喷杆式喷雾机的研究与试验

棉花是新疆兵团农业经济发展的重点和支柱产业,棉花重大病、虫、草害的防治是保证其稳产、高产、高效的重要措施之一。为克服现有机具工作效率低、农药有效利用率低等问题,研制了一种与大马力机车相配套的超宽幅喷杆式喷雾机。该机具主要由机架、动力系统、液压系统、展臂总成、等部件组成,设计的折叠机构、仿形机构和回弹机构有效的减轻了大型喷雾机在运输和工作时对障碍物的碰撞。田间试验表明:该机适用性强,行进灵活,在药箱压力0.5 MPa,喷嘴直径为2.0 mm,喷嘴流量为24 ml/s时,喷雾质量最佳,雾滴中径为57.845μm,雾滴均匀性为0.89,工作性能达到技术规范要求。

Research and Experiment of 3WF-12 Super-Wide of Boom Sprayer

Cotton is the focus and pillar industry of agriculture economic development of Xinjiang Production and Construction Corps.Major disease,insect,weed prevention and control is one of the important measures to ensure its stable and high yield,high efficiency.A super-wide of boom sprayer was designed to overcome the low efficiency of the existing equipment,low effective utilization of pesticides,mainly composed by the rack,power systems,hydraulic systems and other components.The folding mechanism,profile agencies and rebound to effectively reduce large sprayers obstacle collision in transportation and work was designed.Field trials showed that： the applicability of aircraft is strong and travels flexible,when kits pressure is 0.5 MPa,nozzle diameter is 2.0 mm,and nozzle flow rate of 24 ml / s,droplet diameter 57.845 μm,and the droplet uniformity is 0.89,which meets the performance specification requirements.
