本文介绍的耕深测量装置是通过相似三角形原理将一个大位移(耕深)转化为滑块的小位移△y,而不同于国内现有的耕深传感器将耕深同摆杆的摆角θ联系起来,因此原理上不存在非线性向线性转换的问题。测量精度较高,结构比较简单,工作中不需要调整。同国外 The tillage measuring device introduced in this paper transforms a large displacement (tillage) into a small displacement △ y of the slider by the principle of similar triangles. Unlike the conventional tillage depth sensor, the tilling angle θ Therefore, in principle, there is no problem of nonlinear conversion to linearity. High measurement accuracy, the structure is relatively simple, no need to adjust the work. With foreign countries
