Crushed rock applicator mechanism |
摘要 |
A manually manipulatable applicator mechanism for applying and embedding crushed rocks on selected areas of a paved surface. The mechanism includes a first gate structure by which an operator can vary the width dimension of the pattern of applied rocks and a second gate structure for controlling the quantity of rocks applied by the mechanism and thus controlling the thickness of the pattern of applied rocks.
