Abstract

Embodiments described herein relate to plant propagation weight measurement apparatus and methods. Load cells are utilized to measure one or more of seedling trays, flood tables, support systems, and combinations thereof. The load cells are integrated in weight measurement systems and configured to enable weight detection of various system components. In certain embodiments, load cells are utilized to measure stationary system components. In other embodiments, load cells are utilized to measure conveyed system components.

First claim

What is claimed is:

1. A weight measurement apparatus, comprising:
a platform comprising a body having a first member and a second member, the second member disposed substantially perpendicular to the first member;
a hinge coupled between the first member and the second member;
a load cell disposed adjacent to the second member of the body opposite the first member;
one or both of a flood table disposed on the second member of the platform body or a seedling tray disposed in the flood table; and
a structuring element coupled to the load cell.

2. The apparatus of claim 1 , wherein the load cell is a tension load cell coupled to a top surface of the second member.

3. The apparatus of claim 2 , wherein a first connector is coupled between the top surface of the second member and the load cell and a second connector is coupled between the load cell and the structuring element.

4. The apparatus of claim 1 , wherein the load cell is a compression load cell coupled to a bottom surface of the second member.

5. The apparatus of claim 1 , wherein the load cell is a beam load cell coupled to a bottom surface of the second member.

6. A weight measurement apparatus, comprising:
a platform comprising a body having a first end and a second end disposed opposite the first end;
a first load cell coupled to the body adjacent to the first end of the body;
a second load cell coupled to the body adjacent to the second end of the body; and
one or both of a seedling tray or flood table disposed on a top surface of the body between the first end and the second end.

7. The apparatus of claim 6 , wherein the first load cell is coupled to the body laterally outward of the one or both of a seedling tray or flood table.

8. The apparatus of claim 7 , wherein the second load cell is coupled to the body laterally outward of the one or both of a seedling tray or flood table.

9. The apparatus of claim 6 , wherein the first load cell and the second load cell are tension load cells.

10. The apparatus of claim 9 , wherein a first connector is coupled between the top surface of the body and the first load cell and a second connector is coupled between the first load cell and a structuring element.

11. The apparatus of claim 10 , wherein a third connector is coupled between the top surface of the body and the second load cell and a fourth connector is coupled between the second load cell and the structuring element.

12. The apparatus of claim 6 , wherein the first load cell and the second load cell are compression load cells.

13. The apparatus of claim 12 , wherein the first load cell is disposed between a structuring element and a bottom surface of the body.

14. The apparatus of claim 13 , wherein the second load cell is disposed between the structuring element and the bottom surface of the body.

15. The apparatus of claim 6 , wherein the first load cell and the second load cell are beam load cells.

16. The apparatus of claim 15 , wherein the first load cell and the second load cell are disposed between a structuring element and a bottom surface of the body.

17. A plant carrier weight measurement system, comprising:
a plant carrier comprising at least one of a flood table and a seedling tray;
a first tension load cell coupled adjacent to a first end of the plant carrier, the first tension load cell coupled to a top surface of the plant carrier by a first connector and to a structuring element by a second connector; and
a second tension load cell coupled adjacent to a second end of the plant carrier opposite the first end, the second tension load cell coupled to the top surface of the plant carrier by a third connector and to the structuring element by a fourth connector.
