Dump platform materials screener
First Claim
1. A dump platform materials screener, comprising:
- a horizontally fixed support frame;
a materials staging and screening frame, pivotably coupled proximate a first end to a corresponding first end of said horizontally fixed support frame, said materials staging and screening frame movable between a first horizontal material staging and screening frame movable between a first horizontal material staging position to at least a second screening position, said at least a second screening position inclined with respect to said horizontal staging position;
said materials staging and screening frame including;
a materials staging area proximate a second end of said materials staging and screening frame, said materials staging area including a non-screened first bottom region of said materials staging and screening frame on which materials to be screened are dumped when said materials staging and screening frame is in said first horizontal material staging position; and
a materials screening area, adjacent to said non-screened area and extending from said non-screened area to said first end of said materials staging and screening frame, said materials screening area including a second bottom region of said materials staging and screening frame, said second bottom region including at least one screen having at least a first plurality of openings of at least one uniform size, for allowing materials to be screened which are of lesser dimension than said at least one uniform size of at least first plurality of openings to pass through said at least first plurality of openings when said materials to be screened are moved from said materials staging area to said materials screening area; and
a materials staging and screening frame incliner, including a hydraulic piston coupled between said materials staging and screening frame and said horizontally fixed support frame, and actuatable in response to actuation of a materials staging and screening frame incliner actuator including a hydraulic pump actuator valve, for moving said materials staging and screening frame from said first horizontal staging position to said at least a second inclined screening position, said at least a second inclined screening position causing said materials to be screened which are staged on said materials staging area to move from said materials staging area to said screening area, wherein said hydraulic pump actuator valve is actuatable by a remotely controlled hydraulic pump actuator valve.

Abstract
A dump platform materials screener includes a horizontally fixed support frame to which is pivotably coupled a materials staging and screening frame. The materials staging and screening frame includes a materials staging area having a bottom region of non-screened material on which may be dumped materials to be screened. A materials screening area adjacent to the non-screened area is provided which extends from the non-screened materials staging area to a first end of the materials staging and screening frame. The materials screening area includes a bottom region including at least one screen having at least a first plurality of openings of at least a first uniform size, for allowing materials to be screened which are of lesser dimensions than that of the uniform size of the plurality of openings to pass through the plurality of openings when the materials to be screened are moved from the materials staging area to the materials screening area. Also included is a materials staging and screening frame incliner, which is actuatable to cause the materials staging and screening frame to move from a first horizontal staging position to a second, inclined screening position.
