针对水生莼菜植物手工采摘辛苦、效率低下等问题，设计了一种手动控制的莼菜采摘器，分析了其工作原理，给出莼菜切割力计算公式。该采摘器由人手驱动，通过向后逐渐收紧手柄，使与手柄相连的钢丝后移，后移的钢丝再带动直槽形钢片、刀片支架等运动，使主、副刀片闭合，完成莼菜切割运动。然后，操作者将采摘装置移出水面，将切割好的莼菜移到收集装置的网兜上方，松开手柄，主、副刀片自动松开，使莼菜自然落入网兜中。实验表明，该采摘器能达到设计要求，且可靠性高、使用方便、控制灵活，对莼菜和水体均不造成污染。

Am at to solve the problem that brasenia schreberi aquatic plant picked hard and low efficiency by hand , a hand-held picking device for brasenia schreber was designed .Its working principle was introduced , and the calculation formula of brasenia schreberi cutting force was presented .The picking device was driven by hand and by tightening the handle backwards , so that the steel wire connected to the handle moved backward ,the back steel wire drove the piece of straight-shaped steel and the blade holder , closed the main and auxiliary blade and completed cutting brasenia schreberi .Then , the picking device was moved out of the water by the operator , the cut brasenia schreberi was moved to the above net of collecting device ,fell into the net naturally by loosening the handle and releasing the main and auxiliary blade automatically .The picking device of design and manufacture can meet the design requirements through practice test and does not pollute the water and brasenia schreberi .The picking device has the advantages of high reliability , conven-ient to use ,flexible control .
