Abstract
gravity-driven plant cultivation system includes: (a) a frame; (b) a plurality of vertically stacked conveyor assemblies mounted to the frame. Each conveyor assembly includes at least one gravity conveyor extending along a conveyor axis. The conveyor axis slopes downwards relative to a horizontal plane from a frame upstream end to a frame downstream end of the frame. The system further includes (c) a plurality of plant cultivation trays rollingly supported on each gravity conveyor and urged to translate along a respective conveyor axis toward the frame downstream end via gravitational force
Claims (21)
1. A plant cultivation tray for a gravity-driven plant cultivation system, comprising: a) a tray body; 5 b) a plurality of plant cavities in and open to a top of the tray body for holding plants; c) a nutrient chamber internal the tray body and in fluid communication with the plant cavities, the nutrient chamber for holding plant nutrient solution, and the nutrient chamber bounded from below by a nutrient chamber bottom wall of the 10 tray body, the nutrient chamber bottom wall lying in a horizontal plane; and d) wherein the tray body has at least one underside surface for engagement with a sloped gravity conveyor to rollingly support the plant cultivation tray on the gravity conveyor, the at least one underside surface sloping downwards relative to the horizontal plane from a rear of the tray body to a front of the tray 15 body for maintaining a generally constant depth of the plant nutrient solution across the nutrient chamber bottom wall when the tray is supported on the gravity conveyor.
2. The tray of claim 1, wherein the tray body has a pair of the underside surfaces spaced laterally apart from each other for engagement with 20 corresponding supports of the gravity conveyor, and the nutrient chamber bottom wall is laterally intermediate and at an elevation below the underside surfaces.
3. The tray of claim 1 or 2, further including at least one tray vent extending vertically through the tray body for passing air through the tray body to facilitate delivery of air to the plants from below. 25
4. The tray of claim 3, wherein the tray vent passes through the nutrient chamber.
5. The tray of any one of claims 1 to 4, wherein each plant cavity extends vertically between a cavity top end open to the top of the tray body and a cavity bottom end below the cavity top end and positioned in the nutrient chamber.
6. The tray of claim 5, wherein the cavity bottom end of each plant cavity lies 5 in a common bottom plane, the bottom plane parallel with the horizontal plane.
7. The tray of claim 5 or 6, wherein the cavity top end of each plant cavity lies in a common top plane, the top plane parallel with the horizontal plane.
8. The tray of any one of claims 1 to 7, wherein the tray body includes a tray lower portion and a tray upper portion removably nested in the tray lower portion, 10 and wherein the plant cavities are in the tray upper portion, the nutrient chamber is in the tray lower portion, and the tray lower portion comprises the at least one underside surface.
9. The tray of claim 8, wherein the tray lower portion has an upper peripheral edge, and at least a portion of the upper peripheral edge is spaced laterally apart 15 from the tray upper portion by an inlet spacing for delivering plant nutrient solution to the nutrient chamber.
10. The tray of claim 9, where each tray body has a nutrient chamber outlet for draining plant nutrient solution from the nutrient chamber, and the nutrient chamber is laterally intermediate the inlet spacing and the nutrient chamber outlet. 20
11. The tray of any one of claims 1 to 10, wherein the tray body has a plurality of baffles projecting upwardly from the nutrient chamber bottom wall for suppressing slosh of the nutrient solution.
12. The tray of claim 11, wherein the baffles are spaced axially apart from each other and divide the nutrient chamber into a plurality of laterally extending 25 channels.
13. A plant cultivation tray, comprising: a) a tray body; b) a nutrient chamber internal the tray body for holding plant nutrient solution; 5 c) a plurality of plant cavities in and open to a top of the tray body for holding plants, each plant cavity in fluid communication with the nutrient chamber for providing the plant nutrient solution to the plants; and d) at least one tray vent extending vertically through the nutrient chamber between a vent top end open to a top of the tray body and a vent bottom 10 end open to a bottom of the tray body for passing air vertically through the tray body to facilitate delivery of air to the plants from below.
14. The tray of claim 13, wherein the tray body includes a tray lower portion and a tray upper portion removably nested in the tray lower portion, and wherein the nutrient chamber is in the tray lower portion, the plant cavities are in the tray upper 15 portion, and the tray vent passes through the tray lower portion and the tray upper portion.
15. The tray of claim 13 or 14, wherein the nutrient chamber is bounded from below by a nutrient chamber bottom wall of the tray body, and the tray vent comprises a vent projection extending upwardly from the nutrient chamber bottom 20 wall and through the nutrient chamber.
16. The tray of claim 15, wherein the vent projection has a hollow interior in fluid isolation of the nutrient chamber and open to the bottom of the tray body, and a port above the nutrient chamber and providing fluid communication between the vent interior and the top of the tray body. 25
17. The tray of claim 15 or 16, wherein the nutrient chamber bottom wall lies in a generally horizontal plane, and the tray body has at least one underside surface for engagement with a sloped gravity conveyor to rollingly support the plant cultivation tray on the gravity conveyor, the at least one underside surface sloping downwards relative to the horizontal plane from a rear of the tray body to a front of the tray body for maintaining a generally constant depth of the plant nutrient 5 solution across the nutrient chamber bottom wall when the tray is supported on the gravity conveyor.
18. A plant cultivation tray for a gravity-driven plant cultivation system, comprising: a) a tray body having a pair of laterally spaced apart underside surfaces 10 for engagement with laterally spaced apart supports of a sloped gravity conveyor to rollingly support the plant cultivation tray on the gravity conveyor, and a bottom portion laterally intermediate and at an elevation below the underside surfaces for positioning in a conveyor opening between the supports of the conveyor when the tray is supported on the gravity conveyor; and 15 b) a plurality of plant cavities in and open to a top of the tray body for holding plants.
19. The tray of claim 18, wherein the bottom portion comprises a nutrient chamber in fluid communication with the plant cavities, the nutrient chamber for holding plant nutrient solution.
20 20. The tray of claim 19, wherein the nutrient chamber is bounded from below by a nutrient chamber bottom wall lying in a horizontal plane, and the underside surfaces slope downwardly relative to the horizontal plane from a rear of the tray body to a front of the tray body for maintaining a generally constant depth of the plant nutrient solution across the nutrient chamber bottom wall when the tray is 25 supported on the gravity conveyor.
21. A plant cultivation tray substantially as shown and described herein
