A paving material agitation apparatus for use in water channel forming machines comprising a hopper adapted to accommodate therein paving materials to be laid, a plurality of first screws spaced apart with each other in said hopper, a plurality of rotary drives each being secured to one end of said first screws, respectively, an agitation impeller rotatably engaged with one of said first screws, a rotary shaft rotatably supported by said hopper, said agitation impeller being fixedly secured to said rotary shaft so as to be rotated therewith, and a second screw formed on said rotary shaft.

Paving material agitation apparatus for use in water channel forming

A bulldozer assembly has a swivel connection between blade and C-frame for permitting both angling and tilting motions of the former relative to the latter. The swivel connection comprises a swivel block mounted centrally astride the front end of the frame for pivotal or tilting motion relative to same in its lateral direction about a horizontal axis. The swivel block is hingedly jointed to the blade so that the latter may be tilted simultaneously with the block but free to angle relative to same about a normally vertical axis. A tilt cylinder is operatively connected between frame and swivel block, and a pair of laterally spaced angle cylinders between frame and blade.
