Description

Technical Field

[0001] This application relates to the field of greenhouse seedling equipment technology, specifically a greenhouse seedling device. Background Technology

[0002] In the process of seedling cultivation in greenhouses, multi-layer seedling racks have become an important piece of equipment for improving greenhouse utilization and reducing seedling costs because they can make full use of vertical space and increase the number of seedlings per unit area. They are widely used in the large-scale seedling cultivation of vegetables, flowers and other crops. Reasonable spacing between layers can not only provide sufficient growth space for each layer of seedlings, but also ensure air circulation and uniform light in the greenhouse. At the same time, it is convenient for staff to carry out seedling management operations such as watering, fertilizing and inspection.

[0003] Existing multi-layer seedling racks are mostly constructed by welding metal or wood materials and fixing them with bolts. The spacing between each layer of the rack is determined during the manufacturing or installation stage, making it difficult to adjust during subsequent use. When initially setting up the rack, staff will determine and fix the layer spacing based on the height of the seedlings and the expected growth space in the early stages of seedling cultivation. For example, by pre-setting fixing holes on the rack columns, the bolts of the crossbeams of each layer of the rack are locked in the corresponding holes to ensure that the spacing between each layer is uniform and stable. In actual seedling cultivation, seedling boxes are neatly placed on each layer of the rack, and the seedlings grow in the space within their respective layers. Staff will carry out daily management according to the needs of seedling cultivation.

[0004] However, in the actual scenario of cultivating different varieties of seedlings on seedling racks, the growth characteristics of different varieties of seedlings vary. Some varieties of seedlings grow rapidly and are tall, with continuous stem elongation and rapid increase in height during the growth process. Other varieties grow slowly, with short and compact plants, and their overall height is relatively limited after maturity. However, traditional seedling racks use a fixed layer spacing design, which makes it difficult to flexibly adjust the height of the space between layers according to the dynamic growth needs of different varieties of seedlings. This fixed structure affects the growth of tall varieties of seedlings. As the growth cycle progresses, their height will gradually approach or even exceed the fixed layer spacing. The upper support will compress the growth point at the top of the seedling, which will not only force the stem to bend and deviate from the growth direction, but also hinder its normal upward growth. At the same time, the unfolded leaves of the seedlings will repeatedly rub against the surface of the upper support, causing leaf damage and edge withering. This not only damages the integrity of the leaves, but also directly reduces the photosynthetic efficiency, making it difficult for the seedlings to accumulate nutrients. Ultimately, this leads to problems such as weak growth and yellowing leaves, affecting subsequent growth and development. Therefore, it is necessary to provide a greenhouse seedling raising device to solve the above problems. Utility Model Content

[0005] Based on the aforementioned problems in the existing technology, the problem to be solved by this application is to provide a greenhouse seedling raising device that solves the problem that the fixed layer spacing of traditional seedling racks is not easy to adapt to the dynamic growth needs of different varieties of seedlings, resulting in tall seedlings being squeezed, leaves being damaged and growth weakening.

[0006] The technical solution adopted by this application to solve its technical problem is: a greenhouse seedling raising device, comprising:

[0007] Frame;

[0008] A seedling raising assembly is installed on the frame, the seedling raising assembly includes a movable support plate that slides on the frame, and plant seedlings are placed on the movable support plate;

[0009] A height adjustment assembly is mounted on the frame. The height adjustment assembly includes a transition plate that can be raised and lowered vertically while maintaining a horizontal posture. The transition plate is connected to the movable support plate and is adapted to drive the movable support plate to move synchronously.

[0010] Furthermore, the seedling component also includes a fixed support plate installed on the frame, a seedling plate installed on the fixed support plate and the movable support plate, a seedling tray installed on the seedling plate, and a seedling box installed in the seedling tray.

[0011] Furthermore, the movable support plate and the fixed support plate are alternately distributed on the frame.

[0012] Furthermore, wastewater collection boxes are installed on the fixed support plate and the movable support plate, and their coverage area is adapted to the projection area of ​​the seedling plate and the seedling tray above.

[0013] Furthermore, the height adjustment assembly also includes a bracket mounted on the frame, a long rod rotatably connected to the bracket, first bevel gears mounted at both ends of the long rod, an intermediate frame mounted on the bracket, a one-way screw rotatably connected to the intermediate frame, and a second bevel gear capable of meshing with the first bevel gear mounted at one end of the one-way screw;

[0014] The one-way lead screw is fitted with a one-way slider, an intermediate plate is mounted on the one-way slider, and the adapter plate is mounted on the intermediate plate.

[0015] Furthermore, a sliding plate is installed at one end of the unidirectional slider, and a groove adapted to the sliding plate is provided on the intermediate frame.

[0016] Furthermore, an adjustment disc is installed at one end of the long rod.

[0017] The beneficial effects of this application are: the greenhouse seedling raising device provided by this application is connected to the movable support plate through a horizontally lifting and lowering adapter plate, which can drive the movable support plate on which the plant seedlings are placed to flexibly adjust the height, thereby adjusting the seedling growth space as needed, effectively adapting to the space requirements of different growth stages of plant seedlings, preventing the seedlings from being squeezed due to fixed space restrictions, and ensuring the healthy growth of seedlings.

[0027] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0028] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0029] like Figure 1 , Figure 2 and Figure 5 As shown, this application provides a greenhouse seedling raising device, including a frame 1. The frame 1 serves as the supporting structure for the entire seedling raising device. Its overall layout is adapted to the spatial distribution characteristics within the greenhouse, ensuring the stability of its structure to support the weight of multiple seedling raising sections while providing sufficient passage and working space for the seedling raising process. A seedling raising component 2 is installed inside the frame 1. This seedling raising component 2 is used to cultivate seedlings and includes multiple sets of fixed support plates 21 bolted to the frame 1. These fixed support plates 21 serve as fixed support plates in the seedling raising component 2, and their installation positions are determined according to the initial seedling raising plan. The multiple sets of fixed support plates 21 are spaced apart along the vertical direction of the frame 1, forming a basic support plane for multiple seedling raising sections. Multiple sets of movable support plates 22 are slidably installed on the frame 1. The movable support plates 22 and fixed support plates 21 are alternately distributed to jointly form a multi-layer seedling raising space. Their sliding characteristics can be flexibly adjusted according to the changes in space requirements during the seedling growth process.

[0030] Seedling boards 23 are bolted to both the fixed support plate 21 and the movable support plate 22. Seedling trays 24 are bolted to each seedling board 23. The seedling board 23 serves as the direct carrier for the seedling trays 24, and its planar structure ensures sufficient flatness to prevent the seedling trays 24 from tilting or shaking when placed. At the same time, multiple seedling boxes 25 are installed inside each seedling tray 24. The structure of the seedling tray 24 is adapted to the needs of large-scale seedling production, enabling the orderly arrangement of multiple seedling boxes 25. This facilitates unified watering, fertilization, and inspection by staff. The connection between the seedling tray 24 and the seedling board 23 is detachable, making it easy to replace or clean according to changes in seedling varieties. In addition, the seedling box 25 provides an independent growth chamber for single or multiple seedlings, effectively preventing the seedling roots from tangling together and facilitating later seedling division or transplanting. Each seedling box 25 can independently hold substrate and seedlings, ensuring a consistent seedling growth environment.

[0031] Wastewater collection boxes 26 are bolted to the lower parts of both the fixed support plate 21 and the movable support plate 22. These wastewater collection boxes 26 are used to collect water dripping during the seedling cultivation process. Their coverage area is adapted to the projection area of ​​the upper seedling plate 23 and seedling tray 24, ensuring that excess water, nutrient solution, or rinsing wastewater during watering and fertilization can be collected, preventing wastewater from dripping directly onto the lower seedlings and causing pollution to the growth environment. At the same time, a drain pipe (not shown in the figure) is connected to the bottom of one side of the wastewater collection box 26. A valve is installed on the drain pipe. The drain pipe and valve facilitate regular cleaning or discharge by staff, preventing long-term accumulation of wastewater from causing odors or the growth of bacteria. A sealing gasket is installed at the connection between the drain pipe and the wastewater collection box 26 to enhance the sealing of the connection, preventing the collected wastewater and nutrient solution from leaking from the connection gap, and avoiding leakage liquid dripping onto the lower seedlings or device components, thus ensuring a clean seedling cultivation environment.

[0032] Two sets of guide rods 27 are fixedly installed inside the frame 1. The two sets of guide rods 27 are symmetrically distributed along the vertical direction of the frame 1. A guide groove 271 is opened on the frame 1. A guide block 28 is fixedly installed at the corners of both ends of the movable support plate 22. The length of the guide groove 271 is adapted to the adjustment stroke of the movable support plate 22, and its groove size must match the structure of the guide block 28. This ensures that the guide block 28 can pass through smoothly and limits the lateral displacement of the guide block 28, preventing the movable support plate 22 from shifting horizontally during the sliding process. Specifically, the guide block 28 passes through the guide groove 271 and can slide along the rod of the guide rod 27. The sliding cooperation between the guide block 28 and the guide rod 27 enables the movable support plate 22 to run smoothly during the height adjustment process, preventing jamming or tilting.

[0033] like Figures 2-4 As shown, a height adjustment assembly 3 is installed on the frame 1. The height adjustment assembly 3 includes multiple sets of brackets 31 that are bolted to the frame 1. The brackets 31 serve as the mounting base for the height adjustment assembly 3 and have sufficient structural strength to accommodate the operation of the other components of the height adjustment assembly 3. A long rod 32 is rotatably connected to the center of each bracket 31. An adjustment disc 321 is fixedly installed at one end of the long rod 32. The adjustment disc 321 is easy for workers to operate. Its structure is easy to hold by hand or rotate with the help of tools. The long rod 32 can be driven to rotate through simple operation, thereby realizing convenient adjustment of the layer spacing.

[0034] First bevel gears 33 are fixedly installed at both ends of the long rod 32. The first bevel gears 33 rotate coaxially with the long rod 32. An intermediate frame 34 is fixedly installed in the center of the bracket 31. A one-way screw 35 is rotatably connected to the intermediate frame 34. The intermediate frame 34 provides installation support for longitudinal transmission components such as the one-way screw 35. A second bevel gear 36 that can mesh with the first bevel gear 33 is installed at one end of the one-way screw 35. The second bevel gear 36 rotates coaxially with the one-way screw 35. Its meshing with the first bevel gear 33 is used to realize the conversion of the power direction. Through the vertical meshing of the two, the horizontal rotation of the long rod 32 is converted into the vertical rotation of the one-way screw 35.

[0035] Specifically, a dustproof cover (not shown in the figure) is also installed on the intermediate frame 34 at the meshing point of the first bevel gear 33 and the second bevel gear 36 by bolts. The cover can effectively cover the meshing area of ​​the first bevel gear 33 and the second bevel gear 36, reducing the impact of dust and moisture in the seedling environment on the first bevel gear 33 and the second bevel gear 36.

[0036] A one-way slider 37 is threadedly connected to the body of the one-way lead screw 35. The internal thread structure of the one-way slider 37 matches the thread parameters of the one-way lead screw 35. Through the meshing of the threads, the rotational motion of the one-way lead screw 35 is converted into its own linear motion, thereby driving the moving support plate 22 to achieve height adjustment. A slide plate 38 is fixedly installed at one end of the one-way slider 37. A groove 381 adapted to the slide plate 38 is opened on the intermediate frame 34. The cooperation between the slide plate 38 and the groove 381 forms a guide and limit, which is used to restrict the movement trajectory of the one-way slider 37, ensuring that the one-way slider 37 moves only in the vertical direction and avoiding the problem caused by the thread fit clearance. The sliding block offset is minimized, improving the accuracy and stability of height adjustment. The length of the slide groove 381 is matched with the effective stroke of the one-way lead screw 35, providing sufficient space for the sliding plate 38 to slide. At the same time, elastic buffer limit blocks (not shown in the figure) are fixedly installed on the inner walls of both the upper and lower ends of the slide groove 381. These limit blocks can abut against the slide plate 38 when it slides to the end of the slide groove 381, which not only prevents the slide plate 38 from directly hitting the end of the slide groove 381 and causing damage to the components, but also prevents the one-way slider 37 from going out of the groove or getting stuck at the end of the one-way lead screw 35 due to excessive movement, further ensuring the safety and stability of the height adjustment process.

[0037] An intermediate plate 39 is bolted to each of the one-way sliders 37, and a transition plate 391 is bolted to the intermediate plate 39. The intermediate plate 39 serves as a transition component connecting the one-way slider 37 and the transition plate 391. Meanwhile, the transition plate 391 is bolted to the movable support plate 22, so that the height adjustment component 3 drives the movable support plate 22 to move synchronously during the lifting and lowering process.

[0038] Specifically, during the process of adjusting the interlayer spacing according to the growth of seedlings, the corresponding adjustment disc 321 is rotated, driving the long rod 32 to rotate. The first bevel gears 33 at both ends rotate synchronously. Through vertical meshing with the second bevel gear 36, the power is transmitted to the one-way screw 35, causing it to rotate vertically along the intermediate frame 34, thus realizing the conversion of the power direction. When the one-way screw 35 rotates, the thread meshes with the one-way slider 37. Because the slide plate 38 is embedded in the slide groove 381 and is limited, the one-way slider 37 is converted into vertical linear motion. At this time, the power is transmitted to the moving support plate 22 through the intermediate plate 39 and the transition plate 391. Its guide block 28 slides along the guide rod 27, maintaining horizontal lifting and lowering under the action of the guide structure, thus adjusting the interlayer spacing.

[0039] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
