在一次检查作业质量的时候,我们发现有不少机车组的耕作质量不合乎要求。一般是深浅不一致,犁走斜、翻垡不平、犁架变形、机车负荷重,经分析,大部分是由于牵引中心线调整不正确造成的。因此,必须教育机手充分重视机引犁牵引中心线的调整。阻力中心点的确定犁的阻力中心点是耕作时作用于犁上的垂直阻力、前进阻力和侧向阻力等各方面 At a time when inspecting the quality of the work, we found that there was a lack of quality of cultivation in many locomotive groups. In general, the depth is inconsistent, the plow walked oblique, turned uneven, plow deformation, heavy locomotive load, the analysis, mostly due to the traction centerline adjustment is not correct. Therefore, we must give full attention to the education of machine plow traction center line adjustment. Determination of the center of resistance The center of resistance of the plow is the vertical resistance, the forward resistance and the lateral resistance acting on the plow during plowing
