Drive for movable distributor for pourable concrete - has actuator with two drums driven by drive unit, and driver alternatingly connecting distributor to drums

摘要

The driver pin (18) fits on the drive chain (14), and the distributor (3) has two driver stops (19,19'), one of which is connected to one of the drums (15,16), and can be temporarily brought into the running path of the driver (18). The movement path of the distributor is restricted at both ends by limiting guides (8,9) which have rounded surfaces (12,13) for the operating components of the driver stops (19,19'). The driver is formed as a body on the outer radius of the chain, and is roller-shaped which, crossways to the drum longitudinal axis, projects on both sides beyond the circulation plane of the chain. USE - For the distribution of bulk material, such as pourable concrete, in the construction of road surfaces, and similar.
