Description

Technical Field

[0001] This utility model relates to the field of plant seedling technology, and in particular to a mobile seedling rack that is convenient for observation. Background Technology

[0002] Seedling racks are devices used for hydroponics or substrate seedling cultivation, mainly for the cultivation of plant seedlings. They are commonly used in hydroponics, factory seedling production, and other scenarios. Seedling racks provide seedlings with light, water, and nutrients through components such as LED plant growth lights and water supply systems. They are suitable for the cultivation of crops such as sprouts, forage grass, and strawberries.

[0003] Traditional seedling racks consist of seedling trays that are fixed in each layer. The problem is that because the seedling trays are fixed, they are not easy to move, and the seedlings on the inner side are not easy to observe, prune, or maintain.

[0004] Chinese patent CN 221058951 U discloses a greenhouse seedling rack that uses a drive component to push seedling trays outwards to facilitate the display of seedlings within. Problems with the existing technology include: pushing the seedling trays outwards occupies considerable space, which is inconvenient for space planning in a typical seedling room where multiple racks are placed; furthermore, when multiple seedling trays are stacked, pushing the upper trays outwards causes more severe shading of seedlings in lower trays, making it difficult to ensure comparative observation of seedlings on the inner sides of multiple trays; additionally, when hydroponically cultivating seedlings, the current method of simply pushing the trays outwards is not conducive to observing the root development of hydroponic seedlings. Utility Model Content

[0005] To address the problem of excessive space occupation when seedling trays are extended in existing technologies, this invention provides a mobile seedling rack that facilitates observation.

[0006] The technical solution adopted by this utility model to solve its technical problem is: A mobile seedling rack for easy observation includes an interconnected frame and seedling trays. Each seedling tray has a pallet on its inner and outer sides, and a connecting rod. The connecting rod can rotate around its center and slide up and down at its central pivot point. Each end of the connecting rod is connected to a V-shaped plate, which connects to the inner and outer pallets respectively. The V-shaped plates are inverted, with their upper ends rotatably connected to the connecting rod and their lower ends connected to the corresponding pallets on both sides. This ensures that when the connecting rod rotates around its center and the pallets are suspended, the pallets remain stable under gravity. The vertical sliding at the central pivot point of the connecting rod prevents the pallets from interfering with the seedling trays when the connecting rod rotates.

[0007] In this application, two trays are placed inside the seedling tray, one on the inner side and the other on the outer side. A connecting rod connects the two trays at both ends via downward-facing V-shaped plates. When the connecting rod rotates, it causes the trays on both sides to rotate, thus enabling the inner tray to move outwards. The connecting rod's central pivot slides up and down to prevent the seedling tray from contacting the trays and hindering their rotation. This design ensures that the inner tray does not exceed the vertical space occupied by the seedling rack during its outward movement. Furthermore, when configured with multiple seedling trays, the outward movement of seedlings in the upper trays does not affect the observation of seedlings in the lower trays.

[0008] Furthermore, the connecting rod is fixedly connected to the middle of the rotating rod as a pivot, and the seedling tray is provided with a limiting groove to restrict the vertical sliding of the rotating rod; it also includes a support rod and a limiting rod, and a guide groove is horizontally opened on the seedling tray, in which the limiting rod can slide. One end of the support rod is fixedly connected to the rotating rod, and the other end is rotatably connected to the limiting rod, so that when the rotating rod rotates, the limiting rod is subjected to force and slides in the guide groove, thereby driving the rotating rod to slide up and down in the limiting groove.

[0009] Furthermore, the horizontal projection of the rotating rod is located in the center of the guide groove, and when the rotating rod is at the lowest position of the limiting groove, the limiting rod is located at the end of the guide groove.

[0010] Furthermore, it includes a U-shaped sealing plate with its opening facing downwards and connected to the top of the seedling tray, forming a limiting groove that restricts the vertical sliding of the rotating rod.

[0011] Furthermore, connecting rods and V-shaped plates are symmetrically arranged in the left and right directions of each pallet, with the inner and outer sides as the front and back directions.

[0012] Furthermore, multiple seedling trays are fixedly distributed at intervals from top to bottom on the frame.

[0013] Furthermore, the seedling trays have side walls that allow them to hold water, and each tray has multiple through holes. There is a certain distance between the bottom of the tray and the top of the seedling tray.

[0014] Furthermore, the tray is shaped like an upward-facing receiving slot.

[0015] Furthermore, the tray is made of a transparent material.

[0016] The beneficial effects of this utility model are: By placing two trays inside the seedling tray, one on the inner side and the other on the outer side, and connecting the two trays at both ends of a connecting rod via downward-facing V-shaped plates, the rotation of the connecting rod causes the trays on both sides to rotate, thus enabling the inner tray to move outward. The connecting rod's central pivot point slides up and down to prevent the seedling tray from contacting the tray and hindering its rotation. This design ensures that the inner tray's outward movement does not exceed the vertical space occupied by the seedling rack. Furthermore, when configured with multiple seedling trays, the outward movement of seedlings in the upper trays does not affect the observation of seedlings in the lower trays.

[0019] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the present invention will be further described below with reference to the accompanying drawings.

[0020] First, it should be stated that the technical solutions of the embodiments of this application are clearly and completely described. The described embodiments are only some of the embodiments of this application, and not a limitation of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0021] In the description of this utility model, it should be understood that the terms "first", "second", "upper", "lower", "left", "right", "inner", "outer", "axial" or "radial" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings. They are only for the convenience of describing this utility model and are not intended to indicate or imply that the device or element referred to must have a specific orientation structure and operation. Therefore, they should not be construed as limitations on this utility model.

[0022] Reference Figures 1 to 3 As shown, this utility model provides a mobile seedling rack that is convenient for observation.

[0023] A mobile seedling rack for easy observation includes a frame 1 and seedling trays 2 connected to each other. Each seedling tray 2 has a tray 3 on both its inner and outer sides, and a connecting rod 41. The connecting rod 41 can rotate around its center, and its central pivot point can slide up and down. Each end of the connecting rod 41 is connected to a V-shaped plate 43, which connects to the inner and outer trays 3 respectively. The V-shaped plates 43 are inverted, with their upper ends rotatably connected to the connecting rod 41 and their lower ends connected to the corresponding trays 3 on both sides. This ensures that when the connecting rod 41 rotates around its center and the trays 3 are suspended, the trays 3 remain stable under gravity. The vertical sliding of the central pivot point of the connecting rod 41 prevents interference between the trays 3 and the seedling trays 2 when the connecting rod 41 rotates.

[0024] In this application, two trays 3 are set inside the seedling tray 2, distributed on the inner and outer sides respectively. The two ends of the connecting rod 41 are connected to the two trays 3 respectively through V-shaped plates 43 with downward openings. When the connecting rod 41 rotates, it drives the trays 3 on both sides to rotate, realizing the outward movement of the inner tray 3. The middle pivot of the connecting rod 41 slides up and down to prevent the seedling tray 2 from contacting the tray 3 and thus hindering the rotation of the tray 3. With this arrangement, the outward movement of the inner tray 3 does not exceed the vertical space occupied by the seedling rack. Moreover, when configured as a multi-layer seedling tray 2, the outward movement of the inner seedlings in the upper seedling tray 2 will not affect the observation of the seedlings in the lower seedling tray 2.

[0025] It is worth noting that the terms "inner side" and "outer side" here are based on the structure and / or placement of the seedling rack. As shown in the background art disclosure, the seedling rack has support plates on its sides and back, forming the inner and outer sides when the openings face forward; and forming the inner and outer sides when the seedling rack is placed against a wall.

[0026] Obviously, for the purpose of observing the contents of the inner tray 3, the rotation of the connecting rod 41 should enable the inner tray 3 to move to the outer upper space.

[0027] Reference Figure 3 and Figure 4 The upper end of the downward-facing V-shaped plate 43 is rotatably connected to the connecting rod 41 via the first rotating shaft 42, and the lower ends are rotatably connected to the tray 3 via the second rotating shaft 44.

[0028] In this embodiment, to optimize the structure and reduce costs, it is preferable that the two trays 3 corresponding to one seedling tray 2 are synchronized by the same driving component. The rotation of the connecting rod 41 drives the V-shaped plates 43 at both ends to rotate, and each V-shaped plate 43 drives one tray 3, thus achieving synchronized movement of the two trays 3. Furthermore, the upper end of the V-shaped plate 43 is rotatably connected to the connecting rod 41, ensuring stability when the tray 3 is suspended. Obviously, the tray 3 may vibrate or tilt slightly during movement; maintaining stability when the tray 3 is suspended means at least ensuring that the internal load is not spilled out when the tray 3 rotates; ideally, the more stable the better.

[0029] For the purpose of synchronous rotation of the two trays 3, the two trays 3 rotate in opposite directions, and the connecting rod 41 is configured to slide up and down, so that the tray 3 remains suspended during the process of switching the inner and outer sides of the tray 3, so as to avoid interference with the seedling tray 2.

[0030] Obviously, the rotation and vertical sliding of the connecting rod 41 can be implemented by two relatively independent driving components. In this embodiment, the structure of the switching component is further optimized so that the rotation and vertical sliding of the connecting rod 41 produce a linkage effect, thereby further optimizing the structure, reducing costs, and ensuring synchronization.

[0031] Specifically, the connecting rod 41 is fixedly connected to the rotating rod 45 as a pivot, and the seedling tray 2 is provided with a limiting groove for restricting the vertical sliding of the rotating rod 45; it also includes a support rod 51 and a limiting rod 52, and a guide groove 53 is horizontally opened on the seedling tray 2. The limiting rod 52 can slide in the guide groove 53. One end of the support rod 51 is fixedly connected to the rotating rod 45, and the other end is rotatably connected to the limiting rod 52, so that when the rotating rod 45 rotates, the limiting rod 52 is subjected to force and slides in the guide groove 53, thereby driving the rotating rod 45 to slide up and down in the limiting groove.

[0032] Based on the above, the rotating rod 45, the limiting groove, the support rod 51, the limiting rod 52 and the guide groove 53 are linked together so that the rotation of the rotating rod 45 drives the connecting rod 41 to rotate. At the same time, the connecting rod 41 drives the limiting rod 52 to slide in the guide groove 53, which in turn drives the rotating rod 45 to slide up and down in the limiting groove. Simultaneously, the two trays 3 are in a suspended state.

[0033] Furthermore, the horizontal projection of the rotating rod 45 is located in the center of the guide groove 53, and when the rotating rod 45 is at the lowest position of the limiting groove, the limiting rod 52 is located at the end of the guide groove 53.

[0034] This setting is for reference. Figure 1 and Figure 2In the initial state, both trays 3 are located at the bottom of the seedling tray 2, the rotating rod 45 is at the lowest position of the limiting groove, and the limiting rod 52 is located at the end of the guide groove 53. At this time, the rotating rod 45 rotates clockwise, driving the support rod 51 to rotate. Since the limiting rod 52 is limited within the guide groove 53, the limiting rod 52 slides to the left, which causes the rotating rod 45 to move upward, driving the tray 3 upward, thereby avoiding interference between the tray 3 and the seedling tray 2.

[0035] When the limiting rod 52 moves from one side of the guide groove 53 to the other side, the rotating rod 45 moves upward and then lowers to reset. The rotation of the rotating rod 45 causes the inner tray 3 to rotate to a higher position on the outer side, making it easier to observe the growth status of the seedlings on the inner tray 3. The counterclockwise rotation of the rotating rod 45 causes both trays 3 to reset.

[0036] Furthermore, it includes a U-shaped sealing plate 54 with its opening facing downwards and connected to the top of the seedling tray 2, forming a limiting groove that restricts the vertical sliding of the rotating rod 45.

[0037] Furthermore, with the inner and outer sides as the front and back directions, connecting rods 41 and V-shaped plates 43 are symmetrically arranged in the left and right directions of each tray 3.

[0038] This design ensures that the force on tray 3 is more even, making it easier to maintain stability. Obviously, the connecting rods 41 on both sides should remain synchronized during rotation.

[0039] Furthermore, multiple seedling trays 2 are fixedly distributed at intervals from top to bottom on the frame 1.

[0040] When multiple seedling trays 2 are fixedly distributed at intervals on the seedling tray 2, the seedlings on the inner side of the upper seedling tray 2 will move outwards, which will not affect the observation of the seedlings in the lower seedling tray 2.

[0041] In practice, soil cultivation or hydroponics may be used in the seedling tray 2.

[0042] When soil cultivation is used, tray 3 is shaped like an upward-opening container to hold soil and plants.

[0043] When using hydroponics, there are two implementation methods to facilitate observation of the root development of hydroponic seedlings. The first is that the tray 3 is shaped like an upward-opening container trough, used to hold water, and is made of transparent material, allowing direct observation of root development when the tray 3 is suspended. The second is, as shown in this embodiment, the seedling tray 2 has side walls and is shaped like an upward-opening container trough, allowing water to be held inside. Each tray 3 has multiple through holes 31 for seedling transplanting and for the tray 3 to move the seedlings. With this arrangement, when the tray 3 is suspended, the seedling roots extend from the through holes 31, allowing direct observation of root development. As shown in the figure, the multiple through holes 31 are preferably evenly distributed in a multi-row, multi-column matrix.
