ABSTRACT:
A device for removing sand, solid particulate wastes and the like from a surface being cleaned, comprising spade-shaped members driven in a closed rotatory circuit cooperating with a brush in synchronized sweeping motion. In a first embodiment, a rotatory belt mounting a plurality of circumferentially spaced apart spade-shaped collector elements cooperates to receive material swept by a single brush in pendulum arcuate motion and then elevates the waste for deposit into a storage container for later disposal. In a second embodiment, the sweeping action is provided by the reciprocating motion of a first rotational belt mounting a plurality of transverse, circumferentlally spaced-apart rows of brushes and the receiving and elevating is done by a second belt mounting an array of circumferentially spaced-apart spade-shaped collector elements. The first belt and the second belt are driven in counter rotational senses in pre-defined circuits while the first belt is translocated in synchronized reciprocating motion towards and away from the second belt. A stored program device means is provided for synchronizing and controlling both the spade-shaped collector elements and the brushes for removing sand and debris off roadways and the like.
