Shell of device for loading borehole IVSHP 773889.d 1 2 TU

   The shell IVSHP 773889.012 TU is part the polymer hose feeding device in loading dry and watered boreholes. Shell purpose: feeding the polymer hose into a blast borehole on open mining while placing an explosive in the borehole. The shell includes a funnel, cylinders, a cone and a ring. The availability of the ring and number of cylinders (1-3 piece) are determined by a hose length. It is supposed permanent link of the shell parts among themselves. In the process of loading, the shell with the hose typed on it is put in the bore hole mouth. The explosive is filled into the hose through the shell funnel. The hose is pulled off into the borehole by the action of the explosive weight. As the hose is traveling inside the borehole, it is braked by pressing the rubber brake ring to the shell cone.
