旋转开沟机的工作部件兼有切削土壤和运送土壤两种功能。以一次成沟的双圆盘旋转开沟机为例,每个铣刀盘除切削、抛掷本身占据沟形截面的土壤外,还抛掷沟形截面中间部分的土壤(俗称三角土,约占沟形截面的50%左右),这种工作方式正是旋转开沟机的特点和优点。三角土是靠自重塌落在铣刀盘上,这
Rotary ditcher working parts both soil cutting and transporting soil two functions. For example, once ditched double-disc rotary ditching machine, each milling cutter discards the soil which occupies the ditch-shaped section in addition to the cutting and throwing, and also throws the soil in the middle part of the ditch-shaped cross section About 50% of the cross-section), this type of work is the characteristics and advantages of rotary ditching machine. Triangle soil is by self-weight collapse in milling cutter disc, this
