| 摘 要： | 采用气流切割技术设计气流式桑树伐条机。气流切割效能受到压力、流量、喷射形式等多方面因素的影响,设计了适合气流式桑树伐条机作业的气流压力和喷嘴尺寸等,对不同组合的气流压力和不同喷嘴直径进行了桑枝剪切试验。结果表明,在工作压力1.5 MPa、喷嘴直径1.4~1.6 mm的条件下,气流式桑树伐条机的有效剪切直径超过30 mm,工效>2 500株/h;为减少压力损耗,高压输气管长度不宜超过4 m。该机进一步完善消音技术和控制噪音后,有望开发出结构简单、操作方便的实用机型应用于生产。

| Abstract: | We developed an airjet mulberry shoot cutter by employing the airjet cutting technology.Since the cutting efficiency of high pressure airjet can be affected by many factors such as operating pressure,air flow and jet forms,we had investigated suitable values of parameters including air pressure and jet nozzle diameter for the airjet mulberry shoot cutter.The efficiency of mulberry branch cutting was recorded under different operating pressures and jet nozzle diameters.It was found that,when the operating pr... |
