A rotary sampler has cutter knives that are arranged with possibility of rotation with respect to drive axle, it has body that is closed at both sides with support discs, this is formed by track facets of which are installed in turns along the axis, knives and intermediate plates that are immovably connected to each other, and neighboring – with possibility of formation of gaps at period of working cycle and restrictors for prevention of sample fall out placed at the inner surface of each knife, respectively, and intermediate plate. The technical result is in sampling of soils from large depths, high efficiency, and simplicity of construction and sample unloading. |
