    摘要:

    針對(duì)網(wǎng)棚養(yǎng)殖蝗蟲(chóng)的捕集問(wèn)題，設(shè)計(jì)了旋風(fēng)分離式蝗蟲(chóng)吸捕機(jī)。使用CFD軟件對(duì)吸嘴和分離裝置的內(nèi)部氣流場(chǎng)進(jìn)行了數(shù)值模擬。樣機(jī)試驗(yàn)表明：當(dāng)吸嘴傾角為75°、吸口氣流速度為14m/s、吸嘴距地高度為40mm、機(jī)器前進(jìn)速度為0.4m/s時(shí)，可以獲得較高的吸捕率和較低的破碎率。實(shí)際作業(yè)時(shí)可根據(jù)蝗蟲(chóng)分布密度，靈活調(diào)節(jié)吸口風(fēng)速和機(jī)器前進(jìn)速度，以提高吸捕效率、降低能耗。

    Abstract:

    To solve the problem of capturing artificial raised locusts in net house, a cyclone locusts capturing machine is designed. By using CFD software Fluent the airflow field in the suction nozzle and separate device is simulated. The test results of the sample machine indicated that when the inclination angle of suction nozzle was 75°, the airflow speed of the suction nozzle was 14m/s, the distance between the suction nozzle and ground was 40mm and the forward speed of the capturing machine was 0.4m/s, high rate capturing and low rate of break up were got. When practically working in locusts artificial raising net house, the airflow speed of the suction nozzle and the forward speed of the capturing machine were adjusted according to the distribution density of locusts on the ground, to improve the capturing efficiency and reduce the energy consumption.
