[0028] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. The embodiments described below with reference to the drawings are exemplary and are only used to explain the utility model, and cannot be understood as limiting the utility model.

[0029] The following describes an embodiment of the utility model based on its overall structure.

[0030] A variable spectrum LED plant growth box, such as Figure 1 - Figure 5 As shown, it includes a growth box body 1 and a cultivation frame 3. The cultivation frame 3 is installed inside the growth box body 1. Multiple groups of placement grooves 4 are opened on the upper end of the cultivation frame 3. Multiple groups of plants are placed in the placement grooves 4 respectively. The inner wall of the growth box body 1 is symmetrically installed with limit shafts 8, and two groups of limit shafts 8 are connected by synchronous belts. The two groups of limit shafts 8 rotate synchronously. The outer walls of the two groups of limit shafts 8 are movably installed with limit blocks 10, and the inner walls of the two groups of limit blocks 10 are respectively threadedly connected with the outer walls of the two groups of limit shafts 8. The rotation of the limit shaft 8 drives the limit blocks 10 to move. An LED light panel 11 is installed between the two groups of limit blocks 10. The limit block 10 drives the LED light panel 11 to move. A driving motor 5 is installed inside the growth box body 1. A driving shaft 6 is installed at the output end of the driving motor 5, and the driving shaft 6 is movably connected with a group of limit shafts 8. When the driving motor 5 is started, it drives the driving shaft 6 to rotate, thereby driving a group of limit shafts 8 to rotate.

[0031] See also Figure 1 - Figure 3 A driving bevel gear 7 is installed on the upper end of the driving shaft 6, and a limiting bevel gear 9 is installed on one end of a set of limiting shafts 8, and the limiting bevel gear 9 is meshed and connected with the driving bevel gear 7. The driving shaft 6 rotates, driving the driving bevel gear 7 to rotate, and the driving bevel gear 7 is meshed and connected with the limiting bevel gear 9, so the limiting bevel gear 9 rotates, thereby driving the limiting shaft 8 to rotate.

[0032] See also Figure 1 - Figure 4 A water tank 12 is installed inside the growth box body 1, and a water pump is installed inside the water tank 12. A water pipe 13 is installed at the water outlet of the water tank 12. When the water pump is started, water is discharged from the water tank 12 through the water pipe 13.

[0033] See also Figure 1 - Figure 4 A water collecting plate 14 is installed inside the growth box body 1, and the water inlet of the water collecting plate 14 is connected to one end of the water supply pipe 13. Multiple groups of water supply plates 15 are installed on the outer wall of one side of the water supply plate 14. The water supply pipe 13 pumps water into the water collecting plate 14 and enters the multiple groups of water supply plates 15 through the water collecting plate 14.

[0034] See also Figure 1 - Figure 4 Multiple groups of nozzles 16 are installed on the outer walls of the multiple groups of water supply plates 15, and the multiple groups of nozzles 16 are tilted toward the multiple groups of placement grooves 4. The multiple groups of water supply plates 15 respectively pump water sources into the multiple groups of nozzles 16, and spray the water sources into the placement grooves 4 through the nozzles 16.

[0035] See also Figure 4 - Figure 5 A contraction cylinder 17 is movably installed inside the growth box body 1, and the contraction cylinder 17 is connected to the drive shaft 6 through a synchronous belt. A telescopic column 18 is movably installed inside the contraction cylinder 17, and one end of the telescopic column 18 extends into the water pipe 13. A reciprocating thread groove is provided on the inner wall of the contraction cylinder 17, and the inner wall of the contraction cylinder 17 is threadedly connected to the outer wall of the telescopic column 18. The drive shaft 6 rotates, and the drive shaft 6 is connected to the contraction cylinder 17 through a synchronous belt, so the contraction cylinder 17 rotates. Since the inner wall of the contraction cylinder 17 is threadedly connected to the outer wall of the telescopic column 18, the telescopic column 18 is displaced, so that one end of the telescopic column 18 moves out of the water pipe 13.

[0036] See also Figure 1 - Figure 4 A control panel is installed on one side of the growth box body 1, and the control panel is electrically connected to the LED light panel 11, the drive motor 5 and the water pump respectively. The LED light panel 11 is provided with multiple sets of spectrums. The control platform controls the drive motor 5 to start regularly, and starts the LED light panel 11 and the water pump. The LED light panel 11 changes the spectrum regularly.

[0037] The working principle of the utility model is as follows: when the staff uses the LED plant growth box, the staff opens the box door 2 and puts multiple groups of plants into the multiple groups of placement slots 4 at the upper end of the cultivation frame 3, and then closes the box door 2, and controls the driving motor 5 to start regularly through the control platform, and starts the LED light panel 11 and the water pump, and the LED light panel 11 changes the spectrum regularly. When the driving motor 5 starts, the driving shaft 6 rotates, thereby driving the driving bevel gear 7 to rotate, and the driving bevel gear 7 is meshed and connected with the limiting bevel gear 9, so the limiting bevel gear 9 rotates, thereby driving a group of limiting shafts 8 to rotate, and the two groups of limiting shafts 8 are connected by synchronous belts, so the two groups of limiting shafts 8 rotate synchronously, because the inner walls of the two groups of limiting blocks 10 are respectively threadedly connected with the outer walls of the two groups of limiting shafts 8, the two groups of limiting blocks 10 are displaced, thereby driving the LED light panel 11 to displace, and changing the irradiation direction of the multiple groups of plants, so that the multiple groups of plants are evenly irradiated;

[0038] When the drive shaft 6 rotates, and the drive shaft 6 is connected to the shrinking tube 17 through a synchronous belt, the shrinking tube 17 rotates. Since the inner wall of the shrinking tube 17 is threadedly connected to the outer wall of the telescopic column 18, the telescopic column 18 is displaced, so that one end of the telescopic column 18 moves out of the water pipe 13. The water pump pumps water into the water collecting plate 13 through the water pipe 13. The water collecting plate 13 transmits the water to the water supply plate 15 respectively, and sprays it from multiple groups of nozzles 16 to water multiple groups of plants respectively. When the LED light panel 11 stops displacing, one end of the telescopic column 18 re-enters the water pipe 13 to block the water pipe 13.

The specific features, structures, materials or characteristics described may be combined in a suitable manner in any one or more embodiments or examples.
