喷水推进转向式遥控渔药喷施机的设计

Design of the Hydraulic Jet Propulsion Machine for Spraying Fishery Drug

为解决人工泼洒渔药工作劳动强度大、施药效率低且施药过程中渔药对施药人员身体的危害大等问题,利用Solid Works软件进行建模,设计了由直流自吸水泵驱动,自动混药、施药的新型无线遥控喷水推进转向式遥控渔药喷施机。喷施机由船体、动力装置、喷水推进转向系统、施药系统、无线遥控系统以及配套的水管管路系统组成,样机机身质量约为26 kg,并对样机进行测试。结果表明,该渔药喷施机运行平稳可靠、噪音小,作业时的平均行驶速度为1.0 m/s,最大喷施效率约为2.4 hm2/h(传统的人工泼洒效率约为0.4 hm2/h),喷施效率约是人工的6倍。通过遥控控制喷施机完成渔药的喷施,保证了操作人员的安全,同时对渔药进行在线混合,从而避免喷施药液配置过多造成浪费和污染环境,适用于水产养殖。

In order to solve a series of problems-low efficiency, high labor intensity and high harm to operators of artificial sprinkling of fishery drugs, create a modeling design by using “SolidWorks”,a complete new hydraulic jet propulsion ma-chine for spraying fisher^^ drug was designed which was driven by a water pump and could mix drugs automatically. The ma-chine was composed of hull, power device, hydraulic jet propulsion system, drug delivery system, remote control system and pipeline. The sample machine was 26 kg and was tested. The testing results showed that the average speed of the machine was 1.0 m/s, the maximum spraying efficiency was 2.4 m2/h while the efficiency of artificial sprinkling of fishery drugs was 0.4 hm2/h, and spraying efficiency was 6 times of the efficiency of artificial sprinkling. The machine can guarantee the safety of operator by completing the spraying process using the remote control and can reduce the fishery drugs waste and remove environmental pollution because the way of online mixing. It was stable, reliable and applied in aquiculture.
