Abstract: During pneumatic discharging of granulates or other not readily flowable bulk goods from ships by means of a suction nozzle and a suction pipe connected thereto, it is necessary to loosen the material within range of the suction nozzle and to cause walls of material left standing to collapse. To this end, the suction nozzle is provided with a frame or tube surrounding and spaced from it and suspended and supported on it in an elastic manner, the frame having tools on the outer side for intervention in the materials to be extracted by suction, and being capable of being placed in horizontal pivotal oscillation.
