Mixing and pumping unit for continuous production of pumpable building material, e.g. plaster or mortar mixtures

摘要

The device incorporates a drive motor (1) and a mixture vessel (4) equipped with mixing tool (5). The vessel is fed with dry building material and water and a pump (6) is connected to the outlet of the mixture vessel, so that the pumpable material is deliverable via a hose to the processing point. The mixing tool and the pump are drivable from the motor via a gear (2). The gear is formed with two driven shafts (21,22) the first of which (21) is coupled to the mixing tool and the second (22) to the pump. The driven shafts are arranged coaxially with two drive shafts (51,61) and coupled together by inserts couplings.
