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。
In order to achieve the mechanical picking of mulberry leaves for the purpose of the design of a pick mulberry leaf rocker mulberry picking machine, mulberry leaf picking device and intermittent dial positioning device working principle analysis, the establishment of crank-slider mechanism movement Geometric model. Through the matching analysis and calculation of the opening and closing movement time of the symmetrical two-end semi-circular cutter and the movement time of the intermittent dialing device, the angle and the stopping angle of the indexing of the cylindrical indexing cam are determined so that the intermittent dialing positioning device can timely Branches sent to the mulberry positioning box, that is, symmetrical ends of the semi-circular ring tool position, so that the ring tool can accurately mulberry leaves picking action. This research can provide theory and application basis for the mechanization of mulberry leaf picking.
