滚筒梳剪式荔枝采摘部件的设计与优化

Design and optimization of rotary drum combing type of litchi picking machine

摘要:
目的设计一种滚筒梳剪式荔枝采摘试验装置，并优化采摘部件的结构.
方法以齿形板数量、齿形板折弯角度、刀片数量和滚筒转速作为影响因素，以生产率、摘净率和破损率为采摘指标，开展四因素三水平的正交试验.
结果和结论 试验结果表明：齿形板数量为4、齿形板折弯角度为120°、刀片数量为13、滚筒转速为44 r·min^-1时为最优组合，此组合的采摘试验装置生产率为2.604 kg·min^-1.研究结果可为荔枝采摘机械的设计与开发提供参考.

Abstract:
Objective To design a rotary drum combing type litchi picker and optimize structures of picking parts.
Method The four-factor and three-level orthogonal experiment was conducted, using the amount of tooth profile plate, the bend angle of tooth profile plate, the amount of blade and the drum rotation speed as influencing factors, and productivity, picking rate and crushing rate as picking indexes.
Result and conclusion The optimal parameter combination was 4 for the amount of tooth profile plate, 120° for the bend angle of tooth profile plate, 13 for the amount of blade and 44 r·min^-1 for the drum rotation speed The productivity reached 2.604 kg·min^-1 based on the optimal parameter combination. The results provide reference for design and development of litchi picking machine.
