Title: Side mixing blade for trough concrete mixer - is steel-reinforced hard-wearing rubber with prestressed limb
Inventor: STEINBORN WILHELM
IPC: B01F7/00
Filed: 1973-11-10
Abstract: A mixing blade, esp. lateral mixing blade for a trough-type padded concrete mixer, is detachably fixed to a supporting arm and slides on the side wall of the trough. The blade is of hard rubber integrally vulcanised, in the region of its mounting on the arm, to a metal plate, esp. of angle-section with its open side towards the trough wall. The rubber wearing side of the blade widens out as a wedge-shaped section to give a wide contact surface with the wall of the trought, and then continues upwards, generally following the trough wall, as a limb of the cross-section which has a hard-wearing rubber tip bearing with prestress onto the trough wall. The whole of this metal and rubber blade is pref. an integrally vulcanised unit. The low contact press gives a 3 to 4 times increase in working period from one readjustment to the next, as compared with a steel blade. The damping action of the rubber considerably reduces noise and noise-producing vibration of the trough wall.
