ABSTRACT:
Apparatus designed to extract and mix any muddy material from basins or deep morasses with steeply sloping banks and to feed such material in a relatively homogenous form by means of a pressurized propulsion pump integrated into the equipment to a remote treatment station. As seen from downstream to upstream, the equipment comprises a pump for propelling the extracted materials to a remote treatment station by means of a channel, an elevator to pick up the materials in an input bucket and dump them into a feed hopper of the pump, the input bucket bearing laterally two extraction screws and on its forward part an extracting apparatus capable of operating alone or jointly with the extraction screws.
