Abstract

The appliance feeds a binding agent into especially cohesive grounds with high water content. it has a charging container (22) for the agent, with a charging aperture (26), and a ventilation aperture open to the surroundings. A feeder tube (23) connected to the bottom of the container has a discharge opening (34) near its lower end which is closed by a controllable closure device. A vibrator device (24) is positioned within the feeder tube near its lower end and a filling level sensor (41) is also located near the lower end. The feeder tube is elastically suspended from the material container.
