耕宽调节器是犁上一种必要的调节装置,它对保证犁的正常工作状态有重要作用。本文以北方系列设计悬挂犁为例,阐明了耕宽调节器的工作原理,提出了它的设计计算方法和参数选择范围,分析了耕宽调节时耕地机组工作性能的变化情况,并通过田间试验进行了验证。 Plow width regulator is a plow on the necessary adjustment device, it is to ensure the plow’s normal working condition has an important role. In this paper, the northern series of design plow as an example, the working principle of the tillage width regulator is clarified, and its design calculation method and parameter selection range are proposed. The variation of the working performance of the arable land unit when the tillage width is adjusted is analyzed. Verified.
