我们把耙梁相互不固定在一起,而是以铁环(或绳索)将各排单梁铰接起来的钉齿耙称为活节式钉齿耙(简称活节耙)。一般,一片活节耙由一根长单梁和16根短单梁(排列五排)组成。活节耙同普通钉齿耙(指整体式钉齿粑)相比、具有对地面仿形性好、压强小,不易拖土和伤苗少等特点,是一种受欢迎的“苗耙”机械。活节耙和普通钉齿耙虽然都是钉齿耙,但在结构和工作原理上却有区别,这一点往往被忽视,因而在活节耙的设计和使用中常出现错误。比如,为了增加活节耙的工作深度,盲目增加钉齿长度或增加耙体对地面压力,但是却出现了与愿望相反的结果,工作深度反而变浅了。
Instead of fixing the rake beams to each other, we use raipers (or ropes) to articulate the rows of single beams as articulated rakes. In general, a rake consists of a long single beam and 16 short single beams (arranged in five rows). Compared with ordinary nail rake rake (refers to the overall nail 粑) compared with the ground with good shape, low pressure, difficult to drag the soil and less injury and other characteristics, is a popular "mechanical. Although both harrows and ordinary harrows are tooth harrows, they differ in structure and working principle, which are often neglected. Therefore, mistakes often occur in the design and use of harrows. For example, to increase the working depth of an articulated harrow, blindly increase the nail length or increase the pressure of the harrow on the ground, but contrary to the desire, the working depth becomes lighter.
