摘　　要：为解决现有多数葡萄埋藤机埋土量少和埋藤质量差等问题,研制了一种新型冬季葡萄越冬埋藤机。对该机的关键部件:掘土部件,输土机构和减速、换向装置进行了设计研究,并采用正交试验方法进行了田间试验,以掘土铲的长度、纵向输送带的线速度与横向输送带的线速度为因素,以覆土厚度、覆土宽度和抛土距离为指标。在利用试验结果的基础上做出了方差分析,得出影响葡萄埋藤机工作性能的因素主次,进一步优化了组合部件参数。试验结果表明掘土铲的长度为40cm、纵向输送带的线速度为1.4m·s-1、横向输送带的线速度为1.65m·s-1时,葡萄埋藤机的埋藤效果良好,能够满足葡萄越冬埋藤的农艺要求。In view of such problems as little soil covering and low burying quality faced by most of current machines, a new grape vine over-winter burying machine was developed. The key parts of the machine including digging components, soil transmission device, and decelerating and reversing device were designed, and an orthogonal field test was conducted with length of soil digger, linear velocity of vertical soil conveyer and linear velocity of horizontal soil conveyer as factors, and covering depth, covering width and throwing distance as indicators. On the basis of variance analysis of test results, the factors influencing working performance of the grape vine burying machine were analyzed, and the parameters of components were further optimized. The test results showed that, when the length of soil digger was 40 cm, the linear velocity of vertical soil conveyer was 1.4 m·s-1, and the linear velocity of horizontal soil conveyer was 1.65 m·s-1, the grape vine burying machine ran well and could meet the agronomic requirements.
