一、组成 1、手提电钻:系三相十九毫米电钻,并安一倒顺开关。 2、可伸缩传动杆:由二至三根无缝钢管组成。 3、扦样器:由保护螺母、推进筒、芯轴,前端取样筒和侧面取样筒组成。。二、简单原理将传动杆一端插进电钻上,一端由键和保护螺母连接芯轴上。芯轴外面装一螺旋叶子的推进筒。推进筒上端有M 3 0 xl的内螺纹与芯轴上端套合,此纹则起上下变位作用。推进筒有八个小孔,把芯轴上的两个脱销环固定在推进筒上,在两脱销环中间,有一由白合金片复盖并焊牢的长方孔。此孔通过芯轴上
First, the composition 1, portable drill: Department of three-phase nineteen millimeter drill, and security down a smooth switch. 2, retractable transmission rod: from two to three seamless steel tubes. 3, cuttings sampler: by the protection of nuts, propulsion tube, mandrel, front-end sampling tube and side sampling tube. . Second, the simple principle Plug one end of the drive rod into the drill, one end by the key and the nut to connect the mandrel. The mandrel fitted with a propeller of spiral leaves. Propel the upper end of the cylinder M 3 0 xl internal thread and the upper end of the sleeve nested, this pattern is up and down the role of dislocation. Propulsion tube has eight holes, the mandrel on the two unloader ring is fixed on the push tube, in the middle of the two off the pin, there is a white metal sheet covered and welded rectangular hole. This hole passes through the mandrel
