挖坑作業(yè)時，鉆頭隨立軸旋轉(zhuǎn)，同時作軸向移動。土壤在鉆頭的扭矩和軸向力作用下被切削，在工作葉片的擠壓和離心力作用下被松碎，形成土流壓向坑壁，同時沿頁面升運(yùn)到地表。當(dāng)土流運(yùn)動到無坑壁阻擋處時，由于離心力作用碎土被拋到坑的周圍，完成挖坑過程。
During the excavation operation, the bit rotates along the vertical axis and moves axially at the same time. The soil is cut under the action of the torque and axial force of the drill bit, and is loosened under the action of the compression and centrifugal force of the working blade, forming the soil flow pressure to the pit wall, and at the same time, it rises and transports to the surface along the page. When the soil flow moves to the barrier without pit wall, due to centrifugal force, the crushed soil is thrown around the pit to complete the excavation process.
