摘要
针对"一膜两年用"玉米全膜双垄沟田间基肥无法及时准确施入,种植作物需要不同生长阶段的膜下追肥、施肥问题,设计了携有近等速补偿机构的"一膜两年用"玉米全膜双垄沟扎穴施肥装置。通过应用Adams/View和Solid Works Motion虚拟仿真方法,揭示了膜下近似垂直扎穴施肥装置的工作原理,获得施肥穴距为330 mm时近等速补偿机构的最优组合变量,即:L_(AB)长度为60 mm、L_(BC)长度为151 mm、LDE长度为49.035 mm。通过对影响施肥穴距的近等速补偿机构参数进行分析,获得甘肃典型地区不同施肥穴距(200 mm、250 mm和300 mm)下近等速补偿机构所对应的作业参数。
In order to solve the problem of fertilization accuracy in time under film with"one film used for two years"pattern of corn whole plastic-film on double ridges,and the requirements for top dressing under film in different growth stage,the picking hole fertilize mechanism with "one film used for two years"pattern of corn whole plastic-film on double ridges was studied. By applying the virtual simulation method of Adams/View and Solid Works Motion,we revealed the work principle of approximately vertical picking hole fertilize mechanism under film,and obtained the optimal combination variables( length of L_(AB) is 60 mm and length of L_(BC) is 151 mm and length of LDEis 49.035 mm) of compensation mechanism with approximate constant speed when the fertilization hole distance was 330 mm. Through analyzing the influence fertilization hole distance parameter of compensation mechanism with approximate constant speed,we obtained the corresponding operation parameters of compensation mechanism with approximate constant speed under different fertilization hole spacing( 200 mm,250 mm and 300 mm) in typical areas in Gansu province.
