摘 要: | 保护性耕作技术因其具有减少风蚀、保墒、提前播种期等作用,近年来在北方干旱地区得到逐步推广。免耕播种机作为保护性耕作的主要机具,其使用性能直接影响着这一技术的应用。为此,根据目前免耕播种机存在的主要问题,设计了2BQM-6型气吸式免耕播种机,实现了切茬、排茬、施肥、播种及覆土镇压等联合作业。在此基础上,对该免耕播种机重要部件开沟器进行了力学分析,寻找出了开沟器最容易疲劳失效的部位。

Abstract: | Conservation tillage technology can reduce wind erosion, keep moisture, make the action such as seeding time in advance, in recent years it gradually popularized in the northern drought areas.No-till planter as the main tools of conservation tillage, its performance directly affects the application of this technology.According to the current main prob-lems of no-till planter,No-till operation design the 2BQM-6 type no-till planter, implements the cut, fertilization, row crops, sow, cover earth, such as joint operation, field experiments show that the no-till seeder performance indicators meet the requirements.On this basis, using for the mechanics analysis for the vulnerability of no-till planter parts open-er, find out the opener the fatigue failure of the parts, offer the certain reference value to actual production. |
