摘要

SHORT "Device for single or multiple head for extracting furniture, pasty, granular or powdered, wet or not" An apparatus for simultaneously carrying out the extraction in the mass of a pasty, granular or powdery, moist, and the transfer thereof to an intake manifold where it is taken after compacta-ge to be evacuated to a loading station or de-payment. It consists of one or more extraction devices (3) each consisting of one or more ram-pes (4) of spiral helical shape (4a) in the lower part, extended at the top by a single screw helical (4b), the latter operating within a cylindri-that sleeve (1a) or (1b) opens into a housing (1) constituting the intake manifold. The coiled lower part is bordered laterally by a vertical wall (4c) Réali-sant a closed conduit, the upper (4b) and NCI-higher (4a) being separated by a horizontal ceiling or he-licoïdal (4th) surmounted preferably a cylindrical sleeve providing sealing and centering of the whole provision-tif (3) in the sleeve (1a) or (1b). The invention can be used for mud or sand extraction, cereal grain or flour, nodules and all organic and inorganic products.
