DETAILED DESCRIPTION

[0029] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It should be understood that the preferred embodiments are only for illustrating the present invention, rather than for limiting the protection scope of the present invention.

[0030] like Figure 1-Figure 10As shown, the utility model discloses a greenhouse for tobacco seedling cultivation that is conducive to saving space. It includes a seedling shed 1 and a seedling pool 2 located in the seedling shed 1. Seedling racks 3 are distributed in the seedling pool 2. The left and right sides of the lower part of the seedling racks 3 are hinged with first seedling tray mounting frames 4. The seedling racks 3 between the first seedling tray mounting frames 4 are provided with lower cross bars 5. More than one second seedling tray mounting frame 6 is provided on the lower cross bars 5. In the figure, only one second seedling tray mounting frame 6 is arranged between the first seedling tray mounting frames 4. The second seedling tray mounting frame 6 can be arranged along The lower cross bar 5 moves left and right, and a movable connecting device at the free ends of the first seedling tray mounting frame 4 and the second seedling tray mounting frame 6 is provided on the upper side of the seedling rack 3. In this way, when in use, the first seedling tray mounting frame 4 and the second seedling tray mounting frame 6 are rotated and lowered to carry out dry and wet alternating seedling hardening, and the second seedling tray mounting frame 6 can move between the lower cross bar 5, so that the movement can provide space for the first seedling tray mounting frames 6 on the left and right sides to be lowered for wet hardening. This structure can provide more seedling scale with a smaller seedling pool area, which can save seedling space.

[0031] Furthermore, the lower cross bar 5 is located at the front and rear sides of the seedling frame 3, and a sliding sleeve 7 is provided on the lower cross bar 5. The lower side of the second seedling tray mounting frame 6 is hinged to the front and rear two sliding sleeves 7. By pushing the sliding sleeve 7, the second seedling tray mounting frame 6 can be moved left and right on the lower cross bar 5. By adjusting the position of the second seedling tray mounting frame 6, space can be provided for the first seedling tray mounting frame 4 to be placed down for wet refining.

[0032] Furthermore, the movable connection device includes a clamping plate 8 provided at the free ends of the first seedling tray mounting frame 4 and the second seedling tray mounting frame 6, an upper cross bar 9 that cooperates with the clamping plate 8 is provided on the seedling frame 3, a clamping hole is provided on the clamping plate 8, and a clamping pin 10 that limits the upper cross bar 9 is provided in the clamping hole. The clamping plate 8 can be clamped to the upper cross bar 9 by the clamping pin 10. More specifically, the upper cross bar 9 is located on one side or the middle of the seedling frame 3. The upper cross bar 9 is set in the middle of the seedling frame 3, which can achieve better horizontality. It is set on one side of the seedling frame 3, which is more convenient for the movable connection between the first seedling mounting frame 4 and the second seedling mounting frame 6. In the figure, the upper cross bar 9 is located on one side of the seedling frame 3, but in order to ensure horizontality during use, a clamping plate 8, a clamping hole and a manual clamping pin 10 can also be set on the other side of the seedling frame 3. Figure 5 shown.

[0033] Furthermore, a sleeve 11 is provided on the clamping plate 8, and the bayonet 10 is located inside the sleeve 11. Limit blocks are provided at the middle of the bayonet 10 and the outer end of the sleeve 11. A compression spring 12 is provided between the two limit blocks to push the bayonet 10 toward the clamping hole. A pull handle is provided at the outer end of the bayonet 10 for easy hand-holding. The compression spring 12 can keep the bayonet 10 pre-tightened to avoid loosening of the bayonet 10 during use, which would cause the dry-refined seedling installation frame to damage the tobacco seedlings being wet-refined. At the same time, during wet refining, the sleeve 11 on one side of the lowered seedling tray installation frame can be limited by the lower cross bar 5 to achieve horizontal placement of the seedling tray installation frame, such as Figure 4 shown.

[0034] When in use, the second seedling tray installation frame 6 is moved to one end of the lower cross bar 5, and then the upper end is connected to the clamping plate 8 and the upper cross bar 9 by the bayonet 10, and then the first seedling tray installation frame 4 on one side of the seedling rack 3 is lowered for wet refining. Figure 6 and Figure 7 As shown; when the wet refining is completed, it is necessary to fold up the first seedling tray mounting frame 4 that has been wet-refined, flexibly connect its free end to the upper cross bar 9, and then lower the second seedling tray mounting frame 6. After lowering, adjust the second seedling tray mounting frame 6 to be located below and outside the first seedling tray mounting frame 4 that has just been folded up, so as to prevent water drops from the first seedling tray mounting frame 4 that has just been folded up from falling into the lowered second seedling tray mounting frame 6, as shown in FIG. Figure 8 and Fig. 9 When the wet refining of the second seedling tray mounting frame 6 is completed, its free end is movably connected and the whole is moved to one side of the first seedling tray mounting frame 4 that was wet refining first, and then the first seedling tray mounting frame 4 on the other side is lowered for wet refining, as shown in FIG. Fig.10 As shown, when the seedling tray installation frame is lowered, it is required that the wet-refined seedling tray installation frame is placed outside the dry-refined seedling tray installation frame in the vertical direction.

[0035] The above is only a preferred embodiment of the utility model, and does not limit the confidentiality of the utility model in any form. Any simple modification, equivalent change and modification made to the above embodiment based on the technical essence of the utility model without departing from the technical solution of the utility model still falls within the scope of the technical solution of the utility model.
