以松上除草为日的的典齿耙尽管在很早以前就伺世一几退在IJ奉至令还末得到普及·近年来,简一单彩。耘和行间中耕红中耕机采用了高强皮弹簧钢材料·使中澎脚卜的作业范卿从,就连土壤杀件差的石砾地或水改旱、一上块较大的地也可使用,一而卜住很少发生铲柄的折断。祖是,也有一叶部分弹簧钢铲柄由于异常外力作用而损坏,!琳七有必要查明这些铲栖折断的原因并分析研究铲柄的动态特性,找出高遍作业时锄铲所受阻力与土壤坚
Although it was very long ago that a few retreats were not allowed to get popular in IJ until very long ago, simple and monochromatic in recent years. Yun and intercropping red tillage machines using high-strength skin spring steel material, so that the work of Peng Peng Pu in the operation from the grass, even the soil to kill poor gravel or water to drought, a larger block also Can be used, while Bu rarely happen shovel handle broken. The ancestor is also a part of the leaf spring steel shovel handle due to abnormal external force damage! Lin seven need to identify the causes of these shoal breakage and analysis of the dynamic characteristics of the shovel handle to find out when high shovel shovel operation suffered Resistance and soil firmness
