以实现机械采摘桑叶为目的,设计一款能自动采摘桑叶的摇杆式桑叶采摘机,并通过对桑叶采摘装置和间歇拨动定位装置工作原理分析,建立曲柄滑块机构运动的几何模型。通过对称两端半圆环刀具的张闭动作时间与间歇拨动装置运动时间的匹配分析计算,确定了圆柱分度凸轮分度期转角和停歇期转角,使间歇拨动定位装置能及时将桑枝送到桑枝定位框,即对称两端半圆环刀具所在位置,使圆环刀具能对桑叶准确实现采摘动作。该研究可为实现桑叶采摘的机械化提供理论和应用依据。
以實現機械採摘桑葉為目的,設計一款能自動採摘桑葉的搖桿式桑葉採摘機,併通過對桑葉採摘裝置和間歇撥動定位裝置工作原理分析,建立麯柄滑塊機構運動的幾何模型。通過對稱兩耑半圓環刀具的張閉動作時間與間歇撥動裝置運動時間的匹配分析計算,確定瞭圓柱分度凸輪分度期轉角和停歇期轉角,使間歇撥動定位裝置能及時將桑枝送到桑枝定位框,即對稱兩耑半圓環刀具所在位置,使圓環刀具能對桑葉準確實現採摘動作。該研究可為實現桑葉採摘的機械化提供理論和應用依據。

On the purpose of picking mulberry leaves mechanically , a rocker-type mulberry leaves picking machine was designed .According to the analysis of the operational principle of device of mulberry leaves picking and intermittent slide switch positioning , the geometrical models of motional slider-crank mechanism were built .By means of calculating and matching the open and close time of symmetrical semicircular blades and the motional time of the intermittent slide switch , the angle of indexing phase and the dwell of the cylindrical indexing cam have been confirmed , which enabled the mulberry branches be in the baskets where lies the symmetrical semicircular blades by the intermittent slide switch po -sitioning device .Thus the circular blades can pick mulberry leaves accurately .It has been provided of theoretical and practical proofs of picking mulberry leaves mechanization .
