Abstract
A concrete mixer comprising a main frame, a large bearing ring carried by the main frame, the ring supporting an outer barrel carrier for rotation, an inner rotary barrel of elastomeric material supported for rotation by said barrel carrier, the barrel carrier having a number of spaced fingers extending away from the ring, there being a flexible strap extending from each finger to the outer surface of the barrel, so supporting the barrel that its wall can be deflected from the outside to dislodge concrete which might adhere to the inner surface, and an elastomeric rotor supported for rotation within the inner rotary barrel.
Claims12
A concrete turbine mixer having a main frame, a sub-frame, a rotor comprising elastomeric material carried by the sub-frame, mixing blades on the rotor, drive means on the sub-frame coupled for drive to the rotor,
- a bearing ring carried by the main frame, a barrel carrier supported by the bearing ring for rotation about an axis of the bearing ring, the barrel carrier comprising a plurality of supports extending in a direction away from the ring, a barrel of elastomeric material surrounding the rotor but contained within the barrel carrier, a plurality of flexible straps for supporting the barrel, the straps extending between respective said supports and an outer surface of the barrel, there being sufficient spaces between adjacent said supports to provide access to the outer barrel surface for deflection of the barrel wall such as to shed concrete when adhered to an inner surface of the wall.
