    摘要:

    設(shè)計了用于MQ—600型氣流輔助式噴桿彌霧機(jī)的軸流風(fēng)機(jī)。根據(jù)氣流輔助式噴桿彌霧機(jī)噴施作物冠層的末速度原則，確定風(fēng)機(jī)的風(fēng)量、風(fēng)壓和出流速度等參數(shù),；以此作為風(fēng)機(jī)設(shè)計的依據(jù)，設(shè)計計算了軸流風(fēng)機(jī)的比轉(zhuǎn)數(shù),、輪轂比,、外徑,、葉片各截面氣流全壓分布等關(guān)鍵參數(shù)，進(jìn)行了風(fēng)機(jī)葉片選型,、葉片各截面處弦長和葉片數(shù)量計算,。并對風(fēng)機(jī)驅(qū)動系統(tǒng)進(jìn)行了設(shè)計。根據(jù)設(shè)計結(jié)果加工了物理樣機(jī),，并對其性能進(jìn)行了試驗研究,，試驗結(jié)果表明，風(fēng)機(jī)轉(zhuǎn)速1473r/min時,，風(fēng)助風(fēng)筒出口風(fēng)速32.1m/s,， 出口風(fēng)下方0.5m處風(fēng)速8.6m/s，風(fēng)機(jī)性能滿足使用要求,。

    Abstract:

    In order to match the requirements of MQ—600 type air-assisted boom sprayer, the axial fan for air-assisted duct was designed. According to final velocity principle of air-assisted duct on crop canopy, the fan’s air flow, air pressure and the flow velocity and other parameters were determined. The key parameters, such as ratio of axial fan speed, wheel hub ratio, diameter, blade pressure distribution of the whole flow cross-section were calculated. Then, the selection of fan blades, blade chord length of each section was calculated. According to the designed parameters, the physical prototype was built and its performance was studied. The results showed that when the fan speed was under 1473r/min, the outlet wind velocity of the duct was 32.1m/s, and the wind velocity was 8.6m/s at the 0.5m blow the duct, which means the fans met performance requirements. 
