机引犁在作业中,向未耕地方向偏移称为贪生。贪生会使犁侧板、尾轮等的磨损加剧,出现漏耕,耕后沟底不平,同时垡片的翻转和覆盖不良,有时尾轮会离开沟墙跑到未耕地的地面上,使耕深改变,影响了耕翻质量。犁贪生大致有下列几个原因。 1.尾轮不起作用。由于尾轮轴变形或尾轮的水平调整不当,使尾轮失去作用,全部侧向反力都由犁侧板承担,犁侧板对沟墙作用力增大,沟墙严重变形,机引犁向未耕地方向偏移。因此要及时修复变形的尾轮轴,调整尾轮的水平调节螺钉,使尾轮紧压沟墙,一般尾轮轮缘应超出后犁侧板约1～2厘米为宜。
Machine plow in operation, the direction of the uncultivated land offset called greedy. Corruption will increase the plow plow, tail wheel and other wear and tear, tilling occurred tilling uneven after ditch, at the same time 垡 sheet flip and poor coverage, sometimes the tail wheel will leave the ditch wall ran to the uncultivated land on the ground, Deep changes affect the quality of tilling. Plow the greedy for the following several reasons. 1 tail wheel does not work. As the tail shaft deformation or improper adjustment of the tail wheel, so that the role of the tail wheel, all the lateral reaction force borne by the plow side panels, plow side walls of the wall force increases, the serious deformation of the ditch, the machine plow to Unfarm direction offset. Therefore, we must promptly repair the deformation of the tail shaft, adjust the level of the tail wheel adjustment screw, so that the rear wheel squeeze the ditch, the general wheel rim should be beyond the plow side of about 1 to 2 cm is appropriate.
