| 摘 要： | 针对大蒜收获劳动强度大和成本高，结合目前我国大蒜收获的机械化和全自动化程度低的现状，设计了一款大蒜全自动联合收获机，可实现大蒜挖掘、夹持输送、变排传输、根茎切除和蒜头自动装袋全自动一体化收获。首先，阐述了大蒜全自动联合收获机的整体设计结构和各部分工作原理，并对仿形定位料杯和浮动柔性弹簧切根刀具等关键结构进行数值计算分析；其次，通过三维建模分析收获机整体结构尺寸的合理性；最后，制作样机进行多指标正交试验，并综合分析收获机重要部件的作业参数。田间试验计算收获效率为0.04 hm2/h，相较于人工收获效率提高87.5%。

| Abstract: | In order to solve existing problms of garlic harvester，like high labor intensity，high cost of garlic harvest and low degree of current mechanization and automation of garlic harvest in our country，a full-automatic combine harvester of garlic was designed.Whole structure and working principle of each part of garlic full-automatic harvesting machine were described and key structures，profile locating cup and floating flexible spring cutter were further researched.This harvester could realize garlic excavation，gripping transport，variable row transmission，rhizome removal，automatic bag collection of garlic，and so on.The three-dimensional model was established by UGNX10.0 software，and working parameters of important parts of automatic garlic harvester were calculated by field experiment and statistical data analysis.The calculated harvesting efficiency was 0.04 hm2/h，which was 87.5% higher than that of manual harvesting. |
