2BY-6型精密播种机在工作业中,易出现划沟铧开沟质量差,施肥铲晃动、种肥焊合部件之间夹杂物,种子偏垄(较硬地块)等现象。为此我们进行了两项改装。一、划淘锌入土方式的改装划沟铧的作用是划出垄沟,形成沟台分明的垄体。原播种机配带的划沟铧是靠犁辕和铧的重量,入土开沟的。由于犁辕和铧的重量轻,铧尖入土能力差,作业时会出现下 2BY-6 precision planter in the job, prone to poor quality ditch ditch Hua ditches, fertilizer shovel sling, inclusions between fertilizer welding parts, seed partial ridge (harder blocks) and so on. For this we have carried out two modifications. First, the plan to rebuild the method of excavation Amoy Zhaogou Hua Hua’s role is to draw furrows, the formation of clear ditch Taiwan ridge. The original seeder equipped with the ditching channel is by relying on the shaft and the weight of Hua, dug into the soil. Due to the weight of the shaft and the Hua Hua, Hua Jian into the soil is poor, the operation will appear under
