Abstract:  Allium mongolicum Regel has high nutritional value and ecological value. In response to the high labor cost and lack of specialized harvesters for Allium mongolicum Regel, an automated and orderly harvester was designed to complete the harvesting, orderly transportation, and packing operations, aiming to improve the harvesting efficiency and freshness of Allium mongolicum Regel. Based on the analysis of the overall structure of the harvester, the working principle of the whole machine was described. The design of the cutting device, supporting device, conveying device, and other key components were illustrated, and the drive control system of the whole machine was designed. Field harvesting tests were conducted using the effective harvesting rate and stubble trim rate as evaluation criteria to assess the machines operational performance. The results showed that when the machine speed was 3km/h, the effective rate of harvest and stubble trim reached their highest values of 98.4% and 96.2%, respectively. When the stubble height was 2.5cm, the effective harvesting rate and stubble trim rate were 98.3% and 95.9%, respectively. These findings verified that the Allium mongolicum Regel harvester design satisfies the requirement of Allium mongolicum Regel harvesting operations.

摘要： 针对蒙古韭收获作业人工成本高，没有专业收割机械等问题，设计自动有序蒙古韭收割机，一次性完成收割、有序输送及装箱作业，提高收获作业效率和蒙古韭的新鲜度。在分析蒙古韭收割机总体结构的基础上阐述整机的工作原理，对切割装置、扶持装置、输送装置等关键部件进行设计校核后完成样机试制。以有效收割率和割茬整齐率作为评价指标进行田间收割试验，试验表明，当机器前进速度为3km/h，有效收割率和割茬整齐率达到最高值，分别为98.4%、96.2%，当割茬高度为2.5cm时，有效收割率和割茬整齐率为98.3%、95.9%，该蒙古韭收割机满足蒙古韭收割作业要求。
