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 of a predetermined size;
a gear case containing a quantity of gear lubricating oil, said gear case attached to an outside surface 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 unbalanced shafts coupled to a plurality of gears in said gear case; said plurality of unbalanced shafts, when rotated, are configured to create vibration in said screen, said plurality of unbalanced shafts being arranged in a substantially parallel arrangement such that a line drawn through central points of ends of each of said plurality of unbalanced 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 dead zone size regulating information;
means configured for regulating a size characteristic of gear lubricating oil dead zones in said gear case in response to said gear lubricating oil dead zone size regulating information; and
wherein said means disposed inside said gear case which is configured for providing gear lubricating oil dead zone size regulating information, comprises:
a visual 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 of a predetermined size; said screen configured to remove particulate matter smaller than said predetermined size from an input material of particulate matter which contains both particulate matter which is smaller and larger than said predetermined size;
a case containing oil, said case attached to an outside surface 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 unbalanced shafts coupled to a plurality of oil splash lubricated bearings in said case; said plurality of unbalanced shafts, when rotated, are configured to create vibration in said screen and said plurality of unbalanced shafts being arranged in a substantially parallel arrangement such that a line drawn through central points of ends of each of said plurality of unbalanced shafts forms a line which is substantially parallel to said case longitudinal axis;
a mechanism at least indirectly coupled to said housing structure, configured to position said housing structure to be inclined over an extended range of operation angles with respect to a substantially level ground level; wherein said extended range of operation angles extends substantially above 3 degrees;
a means for providing gear lubrication oil dead zone size regulating information comprises one of a visual gear lubricating oil level indicator, a thermometer, and a pressure sensor;
a means for regulating a size characteristic of gear lubricating oil dead zones in said gear case; and
a means for measuring variable slope angles of said screen when said variable slope angles are substantially greater than 3 degrees.

3. The material sorting screen of claim 2 further comprising:
said means for providing gear lubrication oil dead zone size regulating information comprises a visual gear lubricating oil level indicator, a thermometer, and a pressure sensor.

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

5. The material sorting screen of claim 2 wherein said means for measuring variable slope angles comprises a graduated 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 variable slope angles comprises a level integrated within said base.

7. A material sorting screen comprising:
a housing structure, comprising:
a plurality of parallel opposing base side panels each having a longitudinal axis defining a base longitudinal axis;
a screen disposed within and a periphery defined by said plurality of parallel opposing base side panels;
said screen comprising a plurality of openings of a predetermined size;
a gear case containing a quantity of oil, said gear case attached to an outside surface 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 unbalanced shafts coupled to a plurality of at least three oil splash lubricated gears and bearings in said gear case, said plurality of unbalanced 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 plurality of unbalanced shafts being arranged in a substantially parallel arrangement such that a line drawn through central points of ends each of said plurality of unbalanced shafts forms a line which is substantially parallel to said gear case longitudinal axis;
said housing structure is installed at an operational location such that said base longitudinal axis is at an angle of inclination substantially greater than 3 degrees with respect to a horizontal reference line;
a means for measuring variable slope angles of said screen when said variable slope angles are substantially greater than 3 degrees; and
a mechanism at least indirectly coupled to said housing structure, configured to maintain the slope angle of said material sorting screen over an extended range of operation angles.

8. The material sorting screen of claim 7 wherein said means for measuring variable slope angles comprises a graduated scale and said mechanism is a lifting mechanism.

9. The material sorting screen of claim 7 wherein said means for measuring variable slope angles comprises a bubble level integrated within said base.

10. The material sorting screen of claim 7 wherein said mechanism is configured to continuously vary angles of inclination of said housing structure across said extended range of operation angles.

11. The system of claim 7 wherein said plurality of unbalanced shafts and said plurality of gears and bearings comprises three unbalanced shafts and three oil splash lubricated gears and bearings.

12. A material sorting screen comprising:
a structure, comprising:
