[0026] This specific embodiment is a seedling cultivation box with adjustable spacing height, and its structural schematic diagram is as follows Figures 1 - 6 As shown, the seedling cultivation box comprises a rectangular cultivation box 1, a sealed door 2 is provided at one end of the rectangular cultivation box 1, a plurality of trays 3 are provided inside the rectangular cultivation box 1, both sides of the trays 3 are provided with lifting mechanisms for lifting the trays 3, a transverse connecting column 6 is provided at one end of the tray 3, and a limiting mechanism for limiting the movement of the side connecting plate 5 is provided inside the transverse connecting column 6;

[0027] The lifting mechanism includes a rectangular frame 7. One end of the rectangular frame 7 is bolted with a driving motor 8. The output end of the driving motor 8 is fixed with a first longitudinal threaded rod 11. The end of the first longitudinal threaded rod 11 away from the driving motor 8 is fixed with a second longitudinal threaded rod 12. The thread rotation directions of the first longitudinal threaded rod 11 and the second longitudinal threaded rod 12 are opposite. Both the outer sides of the first longitudinal threaded rod 11 and the second longitudinal threaded rod 12 are threadedly connected with longitudinal moving blocks 9. One side of the longitudinal moving block 9 is rotatably connected with an inclined rotating column 10 through a pin shaft. The two inclined rotating columns 10 are cross-designed and the intersection of the two inclined rotating columns 10 is rotatably connected through a pin shaft. The bottom of the inclined rotating column 10 is rotatably connected with a longitudinal moving ring 14;

[0028] A plurality of U-shaped support grooves 4 are evenly arranged at both ends inside the rectangular cultivation box 1. The rectangular frame 7 is located inside the U-shaped support grooves 4 and is slidably connected with the U-shaped support grooves 4, so that the rectangular frame 7 can slide inside the U-shaped support grooves 4;

[0029] A longitudinal sliding groove is opened inside the rectangular frame 7. The longitudinal moving block 9 is located inside the longitudinal sliding groove and is slidably connected with the rectangular frame 7 through the longitudinal sliding groove. Through the setting of the longitudinal sliding groove, the longitudinal moving block 9 can slide inside the rectangular frame 7;

[0030] A longitudinal moving groove is opened inside the side connecting plate 5. The longitudinal moving ring 14 is located inside the longitudinal moving groove and is slidably connected with the side connecting plate 5 through the longitudinal moving groove. Furthermore, when the two inclined rotating columns 10 move, the longitudinal moving ring 14 can slide inside the side connecting plate 5;

[0031] Here, the operation of the driving motor 8 enables the first longitudinal threaded rod 11 and the second longitudinal threaded rod 12 to rotate. The rotation of the first longitudinal threaded rod 11 and the second longitudinal threaded rod 12 enables the longitudinal moving blocks 9 to move inside the rectangular frame 7. The movement of the two longitudinal moving blocks 9 enables the side connecting plate 5 to move vertically through the inclined rotating columns 10, so that the height of the tray 3 can be adjusted, and further the interval height between the two trays 3 can be adjusted;

[0032] The limiting mechanism includes a transverse sliding column 15. The two sides of the transverse connecting column 6 are both slidably connected with the transverse sliding column 15. One side of the transverse sliding column 15 is fixed with a transverse limiting column 16. A rectangular limiting groove adapted to the transverse limiting column 16 is opened inside the side connecting plate 5. A rigid spring 18 is arranged between the two transverse sliding columns 15 and inside the transverse connecting column 6. One end of the transverse sliding column 15 is fixed with a transverse pushing plate 17;

[0033] A transverse sliding groove is provided inside the transverse connecting column 6, and the transverse pushing plate 17 is located inside the transverse sliding groove and is slidably connected to the transverse connecting column 6. Through the setting of the transverse sliding groove, the transverse pushing plate 17 can slide transversely inside the transverse connecting column 6;

[0034] A rectangular through slot is also provided inside the transverse connecting column 6, and the transverse limiting column 16 is slidably connected to the transverse connecting column 6 through the rectangular through slot. Through the provision of the rectangular through slot, the transverse limiting column 16 can pass through the transverse connecting column 6 and enter the inside of the side connecting plate 5;

[0035] Dovetail support blocks 13 are fixed to both ends of the inner side of the side connecting plate 5, and dovetail limit grooves adapted to the dovetail support blocks 13 are opened on the outer side of the tray 3, so that the side connecting plate 5 is installed to the outer side of the tray 3;

[0036] Here, when it is necessary to disassemble the tray 3, the lateral pushing plate 17 is pushed, and the movement of the two lateral pushing plates 17 causes the rigid spring 18 to contract under force, so that the lateral sliding column 15 can slide inside the lateral connecting column 6, and then the lateral limiting column 16 can move out of the inside of the side connecting plate 5, so that the lateral limiting column 16 can release the restriction on the side connecting plate 5, and then through the cooperation of the dovetail support block 13 and the dovetail limiting groove, the tray 3 can be moved out of the inside of the two side connecting plates 5, so that the tray 3 can be disassembled.

[0037] Working principle: When the seedling cultivation box of the present technical solution is used, the operation of the driving motor 8 enables the first longitudinal threaded rod 11 and the second longitudinal threaded rod 12 to rotate, and the rotation of the first longitudinal threaded rod 11 and the second longitudinal threaded rod 12 enables the longitudinal moving block 9 to move inside the rectangular frame 7, and the movement of the two longitudinal moving blocks 9 enables the side connecting plate 5 to be vertically lifted and lowered through the oblique rotating column 10, so that the height of the tray 3 can be adjusted, and then the spacing height of the two trays 3 can be adjusted;

[0038] When the tray 3 needs to be disassembled, the transverse push plate 17 is pushed. The movement of the two transverse push plates 17 causes the rigid spring 18 to be contracted under force, so that the transverse sliding column 15 can slide inside the transverse connecting column 6, and then the transverse limiting column 16 can move out of the inside of the side connecting plate 5, so that the transverse limiting column 16 can release the restriction on the side connecting plate 5, and then the dovetail support block 13 and the dovetail limiting groove cooperate to enable the tray 3 to move out of the inside of the two side connecting plates 5, so that the tray 3 can be disassembled;

[0039] By setting the U-shaped support groove 4, the rectangular frame 7 can slide into the inside of the U-shaped support groove 4, and the rectangular frame 7 can be slid into the corresponding U-shaped support groove 4 according to the corresponding installation requirements.

[0040] All the technical features in this embodiment can be freely combined according to actual needs.

[0041] The above embodiments are preferred implementation schemes of the present utility model. In addition, the present utility model can also be implemented in other ways. Any obvious substitution without departing from the concept of the technical solution is within the protection scope of the present utility model.
