农业机械中工作部件的滑切原理应用十分广泛,如犁铧铧刃角、直犁刀安装角、中耕锄铲翼张角的确定,星形耙片刀口曲线,旋耕刀片刃口曲线,切割器的设计等,都应用了这一原理。但农业机械学中,对这些问题的分析方法很不一致,概念不统一,甚至有些地方有错误,在教学中增加了困难。为此,提出以下建议,以供参考。滑切从运动的观点来看,可分两大类;一类是工作部件作简单运动,另一类是工作 Sliding cutting principle of working parts in agricultural machinery is widely used, such as plowshare blade angle, straight coulter mounting angle, cultivating hoe blade angle determination, star blade curve, rotary blade edge curve, cutter Design, etc., have applied this principle. However, agricultural mechanics, the analysis of these problems is very inconsistent, the concept is not uniform, and even some errors, increasing difficulties in teaching. To this end, the following suggestions are made for your reference. Sliding cut from the sports point of view, can be divided into two categories; one is the working parts for simple exercise, the other is the work
