耕地时,由于工作条件的变化,犁的实际耕宽常常偏离设计值。因此,在犁上通常都装有耕宽调节机构。各种类型的犁,无论是牵引式的、半悬挂式的或悬挂式的,虽然其耕宽调节器的结构型式有所不同,但原理都是一样的。而悬挂犁由于和拖拉机的连接方式比较复杂,耕宽调节造成犁的运动过程也比较复杂,因此,我们在本文中将主要讨论 In cultivated land, due to changes in working conditions, plow actual tillage often deviate from the design value. Therefore, the plow usually equipped with tillage adjustment mechanism. The various types of plows, whether they are trailed, semi-suspended or suspended, have the same principle, although their plow-type governors have different types of construction. The plow and the tractor because the connection is more complex, plowing caused by plowing adjustment process is also more complex, so we will focus on this article
