ABSTRACT:
An ejector-scraper comprising a hopper having an ejector assembly mounted therein for selectively discharging dirt and debris from the interior of the hopper. The ejector is displaced longitudinally through the hopper through a retractable scissors-actuator movably mounted to the rear frame of the ejector-scraper. Suitable links rotatably and slidably couple the actuator to the ejector. The scissor actuator comprises two brackets pivotally coupled at their center points to form an X-shaped lever system. The carriage further comprises pivoting wheel means for selectively raising or lowering the ejector-scraper. The wheel means are attached to the back frame and preferably comprise two pairs of offset, and staggered tires mounted to a rocker in turn pivoted to a V-shaped link. The link is in turn pivoted to a carrier pivotally connected to, and projecting rearwardly from, the scraper. The latter construction enables the wheel means to pivot in response to irregularities in the ground's surface.
