In view of such problems as little soil covering and low burying quality faced by most of current machines,a newgrape 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,linearvelocity of vertical soil conveyerand linearvelocity of horizontal soil conveyer as factors,and covering depth,coveringwidth and throwing distance as indicators.On the basis of variance analysis of test results,the factors influencingworking performance of the grape vine burying machine were analyzed,and the parameters of componentswere furtheroptimized.The testresults showed that,when the lengthof soil diggerwas40 cm, the linear velocity of vertical soil conveyerwas 1.4 m·s-1,and the linear velocity of horizontal soil conveyerwas 1.65 m·s-1,the grape vine burying machine ran well and could meet the agronomic requirements.
