针对中国南方稻田土壤黏重、高含水率土壤使传统油菜开沟起垄机构作业后沟壁易垮塌影响垄沟排水和后期油菜生长,研制了犁旋组合式油菜播种开沟起垄装置。设计了犁体式成沟起垄部件的入土角、翼板角度和翼板长度等结构参数,优化了旋转式切土部件的旋耕弯刀、沟壁切土直刀的安装方式及其结构参数。在室内土槽进行了多因素二次正交旋转组合试验,结果表明:影响沟面宽稳定度、垄高稳定度的主次顺序为沟壁切土直刀的回转半径、翼板长度、翼板角度;影响回土率的主次顺序为翼板长度、翼板角度、沟壁切土直刀的回转半径。装置最优的工作参数组合为沟壁切土直刀的回转半径为351 mm,翼板长度为78 cm,翼板角...

The crop rotation of rice and rapeseed is the main planting pattern for winter rapeseed in South China. In a traditional broad-ridge shallow-furrow planting mode, the ditching machine plow or rotary disc is used to ditch the field. However, the plow cannot solve the problem of high rice stubble in field, while the rotary disc is easy to be entangled by grass and backwater mud in high humidity field, which often causes the traditional parts of ditching and ridging for rapeseed to be loose and collapse. Aimed to solve the problem of high stubble ...
