为了降低牵引阻力,可采用旋转圆盘平切土器(见图)。此工作部件可用在КПΓ-250和КПП-2.2中耕机上,也可用在联合耕作机具上。设计工作部件时,应考虑依靠圆盘的滚动切土,减少滑动切土作用。它由铲柱、支承踵、凿形铲和圆盘组成。圆盘刀可在滚动轴承上灵活转动。为使圆盘刀按同一方向旋转,在安装时,圆 In order to reduce drag resistance, rotating disc flat cutters can be used (see photo). This working part can be used on КПΓ-250 and КПП-2.2 cultivators as well as on joint cultivators. When designing the working parts, it should be considered to rely on the rolling of the disc for soil cutting to reduce the effect of sliding and soil cutting. It consists of shovel columns, support heels, chisel-shaped shovels and discs. Disc knife can be flexible on the rolling bearings. In order to rotate the disc knife in the same direction, the circle is installed
