Description

Technical Field

[0001] This utility model relates to the field of tomato cultivation technology, specifically to a seedling rack for tomato breeding. Background Technology

[0002] Tomato breeding and seedling raising is a relatively common agricultural technique. Tomato seedling raising is beneficial for utilizing artificially created environmental conditions suitable for seedling growth, enabling seeds to germinate and emerge in a timely manner, cultivating strong seedlings with uniform growth, and timely transplanting into the field, which is conducive to early maturity, increased yield and increased income.

[0003] The existing publicly available technology, application number CN202221277844.7, describes a greenhouse frame for tomato seedling cultivation. This frame is constructed by setting a first lead screw, a second lead screw, and a sliding rod, and then by setting a first slider, a second slider, and a third slider, which slide on the first lead screw, the sliding rod, and the third slider respectively. This causes the greenhouse film connected to the bottom of the first slider, the second slider, and the third slider to move. When increased light is needed, the greenhouse film is opened to enhance the growth of tomato seedlings, thereby improving economic benefits.

[0004] Based on the aforementioned patents and the current state of tomato breeding, it is not difficult to find that most existing tomato seedling beds have a fixed size. The biggest problem is that they cannot be adjusted according to different numbers of seedling trays. Placing seedling trays on the seedling bed can easily result in excess space, leading to wasted space and a reduction in the number of seedlings. At the same time, they are not easy to store after use, occupy a large area, and reduce the practicality of the device, indicating room for improvement.

[0005] Therefore, based on this, the technical solution of this utility model is proposed. Utility Model Content

[0006] (a) Technical problems to be solved

[0007] To address the shortcomings of existing technologies, this utility model provides a seedling rack for tomato breeding, which has the advantages of small footprint, easy storage, and high practicality, thereby solving the problems mentioned in the background technology.

[0008] (II) Technical Solution

[0009] To achieve the advantages of small footprint, easy storage, and high practicality, the specific technical solution adopted by this utility model is as follows:

[0010] A seedling rack for tomato breeding includes a base and a support plate. A support plate is welded to the center of the top of the base. Several sets of magnetic grooves are symmetrically formed on both sides of the support plate. A connecting plate is rotatably connected to the bottom of each magnetic groove. A support plate is welded to one end of the connecting plate. Auxiliary grooves are symmetrically formed on both sides of the top of the support plate. A pull rope is installed inside the auxiliary groove. A limit hole is formed on the surface of one end of the pull rope. Fixing blocks are symmetrically welded to both sides of the magnetic groove on the surface of the support plate. Limit grooves are formed on the surface of the fixing blocks. A plug rod is slidably connected inside the limit groove. A spring is sleeved on the outer periphery of the plug rod. The two ends of the spring are fixed to the surface of the fixing block and the surface of the plug rod, respectively. Magnets are embedded in the magnetic groove and on the surface of the support plate.

[0011] Furthermore, several sets of support legs are symmetrically installed on both sides of the bottom of the base.

[0012] Furthermore, a placement groove is provided on the surface of the support plate.

[0013] Furthermore, rotating shafts are symmetrically installed on both sides of the connecting plate.

[0014] Furthermore, mounting holes are symmetrically provided on both sides of the bottom end of the magnetic groove.

[0015] Furthermore, the magnetic groove structure is the same as the connecting plate and the supporting plate structure.

[0016] Furthermore, the depth of the magnetic groove is greater than the thickness of the connecting plate and the supporting plate.

[0017] Furthermore, a gripping groove is provided on one side of the bottom of the support plate.

[0018] The beneficial effects of this utility model are as follows:

[0019] This invention utilizes a foldable and retractable support plate. When tomato seedling cultivation is needed, the corresponding number of support plates can be flipped down according to the number of seedlings required. The support plates are then secured by inserting the connecting ropes on both sides into the fixing blocks. The tomato seedling boxes can then be placed inside the support plates for subsequent seedling cultivation. Since the appropriate number of support plates can be selected based on the number of seedlings, space waste is avoided, thus improving overall practicality. After seedling cultivation, the support plates can be rotated and re-embedded into the magnetic slots. Because both the support plates and the magnetic slots are equipped with magnets, the magnetic attraction between them prevents the structure from falling off, thus achieving efficient storage and reducing the overall footprint. This design offers advantages such as small footprint, easy storage, and high practicality. Attached Figure Description

[0031] Example 1

[0032] refer to Figure 1 , Figure 2 , Figure 3 and Figure 4According to an embodiment of the present invention, a seedling rack for tomato breeding includes a base 1 and a support plate 9. A support plate 2 is welded to the middle of the top of the base 1. Several sets of magnetic suction grooves 4 are symmetrically formed on both sides of the support plate 2. A connecting plate 12 is rotatably connected to the bottom of the magnetic suction groove 4. The support plate 9 is welded to one end of the connecting plate 12. Auxiliary grooves 7 are symmetrically formed on both sides of the top of the support plate 9. A pull rope 6 is installed inside the auxiliary groove 7. A limiting hole 11 is formed on the surface of one end of the pull rope 6. Fixing blocks 5 are symmetrically welded to both sides of the magnetic suction groove 4 on the surface of the support plate 2. A limiting groove 16 is formed on the surface of the fixing block 5. An insert rod 15 is slidably connected internally, and a spring 14 is sleeved around the outer periphery of the insert rod 15. The two ends of the spring 14 are fixed to the surface of the fixing block 5 and the surface of the insert rod 15, respectively. Magnets are embedded inside the magnetic suction groove 4 and on the surface of the support plate 9. A support plate 2 is fixed to the top center of the base 1 by full welding. Multiple sets of magnetic suction grooves 4 (e.g., 6 sets of magnetic suction grooves 4, 2 in each set, symmetrically distributed) are symmetrically opened on both sides of the support plate 2 along the height direction. The magnetic suction groove 4 is a rectangular groove, and a neodymium iron boron magnet is embedded at the bottom of the groove. The bottom of the magnetic suction groove 4 is rotatably connected to the connecting plate 12 via a rotating shaft 13. The rotating shaft 13 passes through both sides of the connecting plate 12 and mates with the bearing holes on the inner wall of the magnetic suction groove 4. The plate can now rotate freely. A support plate 9 is welded to the other end of the connecting plate 12. Magnets matching the magnetic groove 4 are embedded on the surface of the support plate 9 (positional correspondence), ensuring tight adhesion during storage. Folding precision: The depth of the magnetic groove 4 is greater than the thickness of the support plate 9, and the structure of the magnetic groove 4 perfectly matches the support plate 9, ensuring that the support plate 9 can be fully embedded in the magnetic groove 4 when rotated and stored, without any protrusions (the overall width after storage is significantly reduced compared to when unfolded, reducing the floor space). Rotation flexibility: The clearance fit (0.1mm) between the rotating shaft 13 and the bearing hole allows the support plate 9 to rotate smoothly (without jamming), flipping from the stored state (parallel to the support plate 2) to the usage state (perpendicular to the support plate 2). It only takes 5 seconds (single-person operation), and during the flipping process, the connecting plate 12 can completely fit the inner wall of the magnetic slot 4 (without shaking); folding storage: the support plate 9 can rotate around the pivot 13, and when not in use, it is embedded in the magnetic slot 4 and fixed by magnets (without loosening). After multiple sets of support plates 9 are fully stored, the overall volume is reduced compared to the unfolded state, solving the problem of traditional fixed seedling racks being "large in size and difficult to store"; flexible expansion: the number of unfolded support plates 9 can be selected according to the number of seedlings (such as 1-6 sets). A single set of support plates 9 can hold 4 seedling boxes, with a maximum seedling capacity of 24 boxes (increased compared to the capacity of a fixed single-layer rack), realizing "use as needed" and avoiding space waste.

[0033] Example 2

[0034] refer to Figure 1Several sets of support legs 10 are symmetrically installed on both sides of the bottom of the base 1. The base 1 is fixed with bolts to the bottom of the support legs 10, and rubber pads are installed at the bottom. Function: to raise the base 1 to prevent ground moisture from corroding the seedling box, and at the same time, the rubber pads increase friction to prevent the seedling rack from sliding on the smooth ground.

[0035] Example 3

[0036] refer to Figure 1 and Figure 2 The surface of the support plate 9 is provided with a placement groove 8, which is integrally formed on the surface of the support plate 9, and the edge of the groove wall is rounded (R2mm); function: to position the seedling box (to prevent slippage, offset ≤2mm).

[0037] Example 4

[0038] refer to Figure 1 and Figure 2 The connecting plate 12 has symmetrical rotating shafts 13 installed on both sides of the surface. The rotating shafts 13 are designed to be used in conjunction with the mounting holes 3, so as to ensure that the connecting plate 12 can rotate naturally, thereby adjusting the position of the bearing plate 9, which is convenient for seedling cultivation and storage.

[0039] Example 5

[0040] refer to Figure 1 The magnetic groove 4 has symmetrical mounting holes 3 on both sides of the bottom end. The mounting holes 3 are designed to facilitate the connection of the rotating shaft 13.

[0041] Example 6

[0042] refer to Figure 1 The magnetic slot 4 has the same structure as the connecting plate 12 and the support plate 9. The adaptability of the structure is to ensure that the support plate 9 and the connecting plate 12 can be easily stored and folded up, thereby reducing the floor space occupied.

[0043] Example 7

[0044] refer to Figure 1The depth of the magnetic groove 4 is greater than the thickness of the connecting plate 12 and the support plate 9. The depth and thickness are set to ensure that there will be no outward protrusion after storage, thus ensuring the storage quality. Seedling preparation (unfolding the support plate 9): Insert your fingers into the gripping groove of the support plate 9 and pull it outward to rotate the support plate 9 around the rotating shaft 13 (overcoming the magnetic attraction) until it is perpendicular to the support plate 2. Take out the pull rope 6 from the auxiliary groove 7 and pull it to the corresponding fixing block 5. Pull the insertion rod 15 (compressing the spring 14) so ​​that the end passes through the limiting hole 11 of the pull rope 6. After releasing the insertion rod 15, the spring 14 returns to its original position, and the insertion rod 15 locks the pull rope 6. Repeat the operation to unfold 1-6 sets of support plates 9 according to the number of seedlings (e.g., unfold 3 sets if cultivating 10 boxes of tomato seedlings). Seedling operation: Place the tomato seedling boxes into the placement groove 8 of the support plate 9 (arrange them in sections for easy labeling of different varieties). Storage: Pull the insertion rod 15 to disengage from the limiting hole 11, release the pull rope 6 to retract it into the auxiliary groove 7, and rotate the support plate 9 in the opposite direction. Carry the carrier plate 9 close to the support plate 2 until the surface magnets attract the magnets in the magnetic groove 4 (a "click" sound confirms it's in place); after all 6 carrier plates 9 are fully retracted, the seedling rack takes on a "column-like" shape and can be stored against a wall (reducing the footprint compared to the unfolded state); small footprint: the volume is reduced after folding, solving the problem of traditional seedling racks taking up space when not in use (especially suitable for home balconies and small breeding laboratories); easy to store: the magnetic fixing + rotating shaft 13 design makes storage tool-free (can be completed by one person in 1 minute), and the structure is stable after storage (no shaking, no falling off); highly practical: the number of carrier plates 9 can be selected as needed (1-6 sets), suitable for 5-24 boxes of seedlings (improving practicality compared to fixed racks); through the synergistic design of "folding storage + flexible fixing + expansion as needed", this seedling rack takes into account both the practicality of tomato breeding and space utilization, filling the gap of traditional fixed racks that are "single-function and large-footprint".

[0045] Example 8

[0046] refer to Figure 1 and Figure 2A gripping groove is provided on one side of the bottom of the support plate 9. Auxiliary grooves 7 are symmetrically provided on both sides of the top of the support plate 9 (to facilitate the placement of the pull rope 6 into the placement groove 8 for storage when the support plate 9 is flipped and returned to its original position). The pull rope 6 (made of metal) is fixed in the grooves by bolts or welding. A limiting hole 11 is provided at one end of the pull rope 6. Fixing blocks 5 are symmetrically welded to the surface of the support plate 2 and both sides of the magnetic groove 4, with the fixing blocks 5 corresponding to the position of the pull rope 6. A limiting groove 16 is provided on the surface of the fixing block 5, and a sliding connecting rod 15 is provided in the groove. A spring 14 is sleeved around the outer periphery of the rod 15. The two ends of the spring 14 are welded to the surface of the fixing block 5 and the limiting ring of the rod 15, respectively, so that the rod 15 extends a certain distance from the limiting groove 16 in its natural state. The specific distance can be set by the user (to insert the pull rope 6 into the limiting hole 11). The fixation reliability is that the length of the pull rope 6 is adapted to the position of the support plate 9 after it is unfolded (when perpendicular to the support plate 2, the pull rope 6 can naturally tighten). The limiting hole 11 and the... The fitting gap of the insertion rod 15 is ≤0.5mm. After insertion, it can withstand the downward pull of the support plate 9 (preventing the support plate 9 from sagging). The elasticity of the spring 14 ensures that the insertion rod 15 automatically resets (rebounds within 1 second after being pulled out), avoiding the tediousness of manual fixing. Ease of operation: The support plate 9 has a gripping groove at the bottom, which makes it easy to insert fingers to pull the support plate 9 to rotate (effortless design, easy operation). Combined with the quick insertion and removal of the insertion rod 15, "unfolding-fixing" can be completed with one click. Stable support: The combination of the pull rope 6 and the insertion rod 15 fixes the support plate 9 in a horizontal position (perpendicular to the support plate 2), solving the problem of easy sagging when relying solely on the pivot 13 for support, ensuring that the seedling box is placed stably (no risk of tipping over). Quick switching: The "unfolding and fixing-folding and adsorption" switching of the support plate 9 can be completed without tools (the whole process is ≤10 seconds), which is more efficient than the traditional bolt-fixed seedling rack (operation time ≥30 seconds), and is suitable for breeding scenarios with frequent adjustments.
