Applicator and distributor assembly

Abstract

An apparatus capable of self power or being towed and specifically designed to distribute and/or apply cementitious material, and in particular, pervious concrete, over a given surface area such as a roadway or the like. A support frame has mounted thereon a distributor casing specifically configured to direct cementitious material in layer form along a transverse length relative to the direction of travel of the support frame. A delivery hopper moves transversely on the frame and along the length of the casing and serves to continuously feed cementitious material to the casing. Material such as pervious concrete is continuously discharged from the distributor casing by a percussive action imparted to it by forward motion of the frame. A blade element and compacting edge is adjustably positioned above the surface being treated and is attached to the casing to mechanically move therewith so as to compact the cementitious material as it is extruded from the casing upon mechanical actuation thereof. Finishing units comprising a plurality of finishing plates are activated into compressive engagement with the previously laid layer due to its down steam disposition relative to the outlet of the distributor casing. Thus the material can be distributed, applied and finished in a continuous sequence of operative steps employing the subject apparatus.
