Systems, methods and apparatus are provided for monitoring and controlling deposition of secondary crop inputs such as fertilizer and insecticide.

First claim

The invention claimed is:

1. A metering assembly for metering solids, comprising:
a collection portion;
a metering wheel disposed in a bottom of said collection portion and disposed to rotate in a forward direction of rotation about a central axis, said metering wheel having a plurality of pockets radially spaced around an outer peripheral surface of the metering wheel, each of the plurality of pockets having an open end at said outer peripheral surface of said metering wheel, each one of said plurality of pockets having a forward surface and a rearward surface relative to said forward direction of rotation, said forward surface having a forward-swept orientation relative to a line extending from said central axis of said metering wheel to a bottom of each pocket, and said rearward surface having a portion that curves forwardly from said bottom of each pocket toward said forward direction of rotation;
a cover disposed vertically above the metering wheel and within said collection portion, said cover having internal sidewalls defining an opening for conveying the solids from said collection portion to said metering wheel.

2. The metering assembly of claim 1 , wherein the metering wheel further comprises circumferential lips extending a radial distance greater than a radial distance to said open end of each of said plurality of pockets.

3. The metering assembly of claim 1 , wherein the metering wheel comprises two parts.

4. The metering assembly of claim 1 , wherein the metering wheel further comprises circumferential lips extending a radial distance greater than a radial distance to said open end of each of said plurality of pockets, and said internal sidewalls extending below said circumferential lips.

5. The metering assembly of claim 1 , wherein the cover further comprises a cleaning surface disposed to remove excess material from said metering wheel as the metering wheel rotates under the cover.

6. The metering assembly of claim 1 , further comprising a drive for rotationally driving the metering wheel.

7. The metering assembly of claim 1 , wherein the solids are granular or powdered.

8. The metering assembly of claim 1 , wherein the solids are at least one of fertilizer, insecticide, fungicide, and herbicide.

9. A metering assembly for metering solids, comprising:
a metering wheel having a plurality of pockets radially spaced around an outer peripheral surface, each of said plurality of pockets having an open end at said outer peripheral surface, said metering wheel disposed to rotate in a forward direction of rotation about a central axis;
a collection portion in communication with a portion of said outer peripheral surface of said metering wheel as said metering wheel rotates; and
a cover disposed above said metering wheel and within said collection portion, said cover having internal sidewalls defining an opening through which solids collected in said collection portion enter said open end of at least one of said plurality of pockets as said metering wheel rotates, wherein said cover further comprises a cleaning surface disposed to remove excess material from said metering wheel as said metering wheel rotates under said cleaning surface.

10. The metering assembly of claim 9 , wherein the metering wheel further comprises circumferential lips extending a radial distance greater than a radial distance to said open end of said at least one of said plurality of pockets.

11. The metering assembly of claim 10 , wherein said internal sidewalls extend below said circumferential lips.

12. The metering assembly of claim 9 , wherein the metering wheel comprises two parts.

13. The metering assembly of claim 9 , wherein the solids are granular or powdered.

14. The metering assembly of claim 9 , wherein the solids are at least one of fertilizer, insecticide, fungicide, and herbicide.
