分段式大蒜收获机械结构简单、成本低廉、操作简便,可减少用工,具有很大的开发潜力,但缺乏成熟机具。针对市场上三种典型的分段式大蒜收获机进行了田间性能试验,试验了挖掘深度、机具行进速度和输出轴转速等参数对收获性能的影响;评价了各种机型的损失率、伤蒜率、含土率、生产率等主要性能指标,为分段式大蒜收获机的改进设计提供参考。 Segmented garlic harvester mechanical structure is simple, low cost, easy to operate, can reduce labor, has great potential for development, but the lack of mature equipment. Three typical segmented garlic harvesters on the market were tested for field performance. The effects of excavation depth, traveling speed of implement and output shaft speed on the harvesting performance were tested. The loss rate and injury of various models were evaluated Garlic, soil content, productivity and other major performance indicators for the improved design of the segmented garlic harvester provide a reference.
