Abstract

Disclosed is a vibrating material sorting screen with a substantially variable tilt angle and a tilt angle measuring device where the screen has a gear box which is horizontal when the screen is horizontal and inclined when the screen is inclined and further where the gear box has a plurality of oil level sensors or indicators therein which are sized, placed and configured to provide proper oil volume while the screen is oriented horizontally or at various inclines.

First claim

I claim:

1 . A material sorting screen comprising:
a housing structure, comprising a base having a base longitudinal axis; a screen at least indirectly coupled to and disposed at least in part within said housing structure, said screen comprising a plurality of openings; a gear case configured for containing a quantity of gear lubricating oil, said gear case attached to an portion of said housing structure; and having a gear case longitudinal axis which is oriented so as to be at a fixed angle with said base longitudinal axis; a plurality of at least three shafts coupled to a plurality of gears in said gear case; said plurality of shafts, when rotated, are configured to create vibration in said screen, said plurality of shafts being arranged in an arrangement such that a line drawn through points of ends of each of said plurality of shafts, forms a line which is substantially parallel to said gear case longitudinal axis, and said plurality of gears comprises at least three oil splash lubricated gears; a means disposed inside said gear case which is configured for providing gear lubricating oil information; means configured for regulating a size characteristic of gear lubricating oil zones in said gear case in response to said gear lubricating oil information; and wherein said means disposed inside said gear case which is configured for providing gear lubricating oil information, comprises: an indicator for displaying a level of gear lubricating oil in a downhill end of said gear case when said gear case is inclined by substantially more than 3 degrees and wherein said fixed angle is substantially 0 degrees.

2 . A material sorting screen comprising:
a housing structure, comprising a base having a base longitudinal axis; a screen at least indirectly coupled to said housing structure, said screen comprising a plurality of openings; said screen configured to pass particulate matter smaller than said plurality of openings from an input material of particulate matter which contains both particulate matter which is smaller and larger than said plurality of openings; a case configured for containing oil, said case attached to a portion of said housing structure; and having a case longitudinal axis which is oriented so as to be at a fixed angle with said base longitudinal axis; a plurality of shafts coupled to a plurality of oil splash lubricated bearings in said case; said plurality of shafts, when rotated, are configured to create vibration in said screen and; and a means for measuring a slope angle of said screen when said slope angle is substantially greater than 3 degrees.

3 . The material sorting screen of claim 2 further comprising:
A lifting mechanism at least indirectly coupled to said housing structure, configured to position said housing structure to be inclined over a range of operation angles with respect to a substantially level ground level; wherein said range of operation angles extends substantially above 3 degrees; and
a means for providing gear lubrication oil information comprises one of a gear lubricating oil level indicator, a thermometer, and a pressure sensor.

4 . The material sorting screen of claim 2 further comprising: a means for measuring a slope angles of said housing structure; and a means for regulating a size characteristic of gear lubricating oil zones in said case.

5 . The material sorting screen of claim 3 wherein said means for measuring a slope angle comprises a scale and said means for regulating comprises a system for processing data and a touch screen display.

6 . The material sorting screen of claim 2 wherein said means for measuring a slope angle comprises a level integrated within said base.

7 . The material sorting screen of claim 3 wherein said lifting mechanism is configured to vary angles of inclination of said housing structure across said range of angles.

8 . A material sorting screen comprising:
a housing structure, comprising: a plurality of base side panels each having a longitudinal axis defining a base longitudinal axis; a screen disposed within space defined by said plurality of base side panels; said screen comprising a plurality of openings; a gear case configured for containing a quantity of oil, said gear case attached to a portion of said housing structure, and having a gear case longitudinal axis which is oriented so as to be substantially parallel with said base longitudinal axis; a plurality of shafts coupled to a plurality of at least three oil splash lubricated gears and bearings in said gear case, said plurality of shafts extending in a direction substantially orthogonal to said longitudinal base axis which when rotated, are configured to create vibration in said screen; and said housing structure is configured to be disposed in an operational orientation such that said base longitudinal axis is at an angle of inclination substantially greater than 3 degrees with respect to a horizontal reference line.

9 . The material sorting screen of claim 8 further comprising:
a means for measuring a slope angle of said screen when said slope angle is substantially greater than 3 degrees; and
a mechanism at least indirectly coupled to said housing structure, configured to maintain a slope angle of said material sorting screen over a range of operation angles.

10 . The material sorting screen of claim 9 wherein said means for measuring a slope angle comprises a scale and said mechanism is a lifting mechanism.

11 . The material sorting screen of claim 9 wherein said means for measuring a slope angle comprises a bubble level integrated within said base.

12 . The material sorting screen of claim 9 wherein said mechanism is configured to vary angles of inclination of said housing structure across said range of operation angles.

13 . A method of sorting material comprising the steps of:
providing a material sorter having a material receiving surface; providing a plurality of shafts, configured to manipulate said material receiving surface; providing a plurality of gears each coupled to one of said plurality of shafts; providing a means for housing oil lubricating said plurality of gears; and simultaneously varying, in unison, a slope angle of said material receiving surface and a slope angle of said means for housing oil, both with respect to a ground reference over a range of angles which is substantially greater than 3 degrees.

14 . The method of claim 13 further comprising the steps of:
providing a means for measuring an oil level at a downhill end of said means for housing when said plurality of shafts are not rotating.

15 . A method of claim 13 wherein said plurality of gears comprises at least three gears, where each of said plurality of gears is directly coupled to one and only one of said plurality of shafts.

16 . The method of claim 13 further comprising the steps of providing a means for varying an incline of said material receiving surface over a range of angles where said range of angles is substantially greater than 3 degrees.

17 . The method of claim 13 wherein said material sorter is a screen.
