Portable classifier screen shaker assembly

摘要

A sifting screen shaker assembly defined by a generally vertical hollow frame includes a pivotally supported yoke at its base provided with a foot pedal at its apex to articulate a pair of vertical links that are confined in their motion by the convolutions of shaped apertures, with the ends of the links articulating a screen assembly supported within a hinged tray above a collection receptacle in which the sifted particulates passed by the screen assembly are collected while additional particulates are added. The particulates accumulated in the screen assembly are then periodically discarded by articulating the tray around its hinge.

主权项

1. A foot actuated apparatus for imparting foot actuated sifting movement to a screen assembly containing granular matter and deployed for concurrent receipt by way of manual translation of additional granular matter, comprising:
a generally vertical support frame defined by an upper and a lower end and including an interior space conformed for receiving a collection receptacle proximate said lower end and a convolved aperture proximate said upper end; a pivotally mounted pedal deployed for said foot actuated movement proximate said lower end of said support frame and connected to articulate a link in an engaged translation confined within said convolved aperture; and mounting means operatively connected to said link for supporting said screen assembly above said collection receptacle in an alignment for said manual translation of said additional granular matter.
