First Claim
1. A vibratory material separating apparatus comprising:
- a conveying surface for moving a composite mixture in a conveying direction between an inlet end and a discharge end, the conveying surface having a first conveying plateau and a second conveying plateau spaced from the first conveying plateau toward the discharge end to form a drop out opening between the first and second conveying plateaus, the first conveying plateau directing the composite mixture substantially along a plane adjacent the drop out opening and having an edge at the drop out opening, the second conveying plateau having a landing area including at least a portion spaced beneath the edge of the first conveying plateau;
a vibratory actuator for vibrating the conveying surface to effect vibrating movement of the composite mixture;
a source of pressurized air including at least one pressure chamber and a blower communicating through the at least one pressure chamber; and
a deflector plate for directing air from the pressurized air source through the drop out opening and angularly upward with respect to the plane of the first conveying plateau and from underneath the composite mixture moving over the first conveying plateau edge, the deflector plate cooperating with the pressure chamber to define an air duct, the deflector plate being shiftable between a first position, wherein the deflector plate is shifted towards the first conveying plateau so that the air duct has a first width, and a second position, wherein the deflector plate is shifted away from the first conveying plateau so that the air duct has a second width larger than the first width.

Abstract
A vibratory material separating apparatus has at least two plateau conveying surfaces interrupted by a drop out opening. A composite mixture is conveyed by a vibrating action beyond the first conveying plateau and over a foraminous section in the first conveying plateau adjacent the drop out opening. Air is directed upwardly through the foraminous section to break apart the composite mixture, and an air supply formed by an air duct is also directed angularly in relationship to the plane of the first conveying plateau to further break apart the composite mixture and to propel particles of predetermined density and/or dimension to the landing area on the second conveying plateau. The air duct is adjustable between a first position and a second position to form an air stream having an adjustable and width. In another aspect, a separating tube is located between and spaced from the first and second conveying plateaus, within the drop out opening. The separating tube interacts with the air stream produced by the air duct to assist in carrying particles passing over the leading edge of the separating tube over the drop out opening and onto the landing area of the second conveying plateau.
