摘要
针对我国西北地区固定垄保护性耕作条件下,玉米茬地垄作免耕播种小麦秸秆堵塞严重和播种质量差等问题,设计了一种驱动圆盘式固定垄小麦免耕播种机。整机主要由驱动圆盘式破茬装置、开沟施肥装置、单体仿形播种装置及镇压传动装置等组成。田间试验结果表明,驱动圆盘刀的平均入土深度为10cm,平均播种和施肥深度分别为5cm和10cm。该机一次作业可完成破茬、开沟施肥、播种和镇压等工序,作业时土壤扰动小,播种作业质量可满足西北地区农艺要求。
Aimed at the permanent raised.beds conservat ion tillage wheet planting in northwest of china,corn root field no till planter＇ s blockage and bad planting quality, a new type of wheat planter was designed. The new type planter consists of a power driven corn roots talk cutting device, an opening and fertilizing device, a planting device and a pack roller. The field tests approved that the driven disc＇s average ditch depth is 10cm,the average depth of fertilizing is 10 cm,the average depths of seeds are 5cm. This planter can perform the corn roots talk cutting, opening,fertilizing, seeding, and packing operations once. It works with little interference to s oil and its seeding quality meets the agricultural requirement.
