Description

Technical Field

[0001] This utility model relates to the field of soilless cultivation technology, and in particular to a soilless cultivation rack for celery cultivation. Background Technology

[0002] Soilless cultivation is an innovative agricultural planting model that uses soil-free media (such as loose banana peels, ferns, mosses, or hydroponics) and nutrient solutions to supply the nutrients and support needed for plant growth. This technology has many advantages, including increased yield, shorter growth cycle, reduced incidence of pests and diseases, and conservation of water and land resources. Soilless cultivation is not only suitable for vegetable cultivation, such as celery, but is also widely used in the production of various crops such as flowers, medicinal herbs, fruits, and grains. In soilless cultivation, the cultivation rack plays an important role, not only supporting the plants and providing growing space, but also optimizing the planting environment.

[0003] Traditional hydroponic cultivation racks for celery typically employ a fixed, multi-layered structure. In practice, this limits the adaptability to the different growth stages of celery and makes it difficult to optimize space utilization. Furthermore, this fixed structure hinders the adjustment of planting density and growing environment, thus limiting planting flexibility and efficiency. Additionally, the fixed spacing leads to uneven light and ventilation, further impacting the growth quality of the celery. Utility Model Content

[0004] The technical problem to be solved by this utility model is that most of the existing soilless cultivation racks for celery cultivation are fixed multi-layer structures, which limit the adaptability of cultivation and the flexibility of environmental adjustment during the cultivation process, and lead to uneven light and ventilation, thus affecting the growth quality. Therefore, we propose a soilless cultivation rack for celery cultivation.

[0005] To achieve the above objectives, this application adopts the following technical solution: a soilless cultivation rack for celery cultivation, comprising a base, a support column fixedly connected to the top of the base, two circular frames slidably connected to the surface of the support column, L-shaped frames fixedly connected to both sides of the top of the circular frames, a fixed shell fixedly connected to the top of the L-shaped frames, a pull rod slidably connected inside the fixed shell, a circular plate fixedly connected to one end of the pull rod, a trapezoidal block fixedly connected to the other end of the pull rod, a movable plate fixedly connected to the bottom of the trapezoidal block, a locking block fixedly connected to the top of the movable plate, multiple slots for cooperating with the locking blocks being opened on the surface of the base, a pull plate slidably connected to the surface of the pull rod, fixing blocks fixedly connected to both ends of the pull plate, and two fixing holes for cooperating with the fixing blocks being opened on both sides of the front end of the fixed shell.

[0006] Preferably, a first spring is slidably connected to the surface of the pull rod, one end of the first spring is fixedly connected to the circular plate, and the other end of the first spring is fixedly connected to the pull plate.

[0007] Preferably, limiting blocks are fixedly connected to both sides inside the fixed shell, the limiting blocks are located on both sides of the trapezoidal block, and one side of the limiting block is slidably connected to the trapezoidal block.

[0008] Preferably, sliders are fixedly connected to both sides of the movable plate, and grooves that cooperate with the sliders are opened on both sides inside the fixed shell.

[0009] Preferably, the bottom of the movable plate is fixedly connected to two second springs, which are located on both sides of the locking block, and the other end of the second springs is fixedly connected to the inside of the fixed shell.

[0010] Preferably, a number of cultivation pots are fixedly connected to the surface of the circular frame. The cultivation pots are distributed in a circle. The bottom of the cultivation pots is provided with multiple ventilation holes and a water storage layer is provided at the bottom of the cultivation pots.

[0011] Preferably, the surface of the circular frame is provided with a groove, the groove is located directly below the cultivation pot, a drain pipe is fixedly connected to one side of the circular frame, a liquid storage tank is provided below the drain pipe, and a filter plate is slidably connected inside the liquid storage tank.

[0012] The technical effects and advantages of this utility model are as follows:

[0013] In this invention, by pulling the pull plate outward, the fixing block is disengaged from the fixing hole. Pulling the pull rod moves the trapezoidal block upward, which in turn moves the moving plate, causing the locking block to disengage from the slot. This releases the fixing between the support column and the circular frame, allowing the circular frame to be positioned and the two circular frames to maintain the distance between each layer. Simultaneously, through the above process, the height of the multi-layer cultivation rack can be adjusted, ensuring that each layer of the circular frame receives sufficient sunlight for effective photosynthesis and nutrient absorption. This better adapts the celery to environmental conditions at different growth stages, promotes healthy celery growth, and improves planting flexibility. Attached Figure Description

[0020] The present invention will now be described in further detail with reference to the accompanying drawings and preferred embodiments. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0021] Reference Figure 1 - Figure 5 As shown, this utility model provides a technical solution: a soilless cultivation rack for celery planting, including a base 1, a support column 2 fixedly connected to the top of the base 1, two circular frames 3 slidably connected to the surface of the support column 2, L-shaped frames 4 fixedly connected to both sides of the top of the circular frames 3, a fixed shell 5 fixedly connected to the top of the L-shaped frames 4, a pull rod 6 slidably connected inside the fixed shell 5, a circular plate 7 fixedly connected to one end of the pull rod 6, a trapezoidal block 8 fixedly connected to the other end of the pull rod 6, a movable plate 9 fixedly connected to the bottom of the trapezoidal block 8, a locking block 10 fixedly connected to the top of the movable plate 9, multiple slots 11 for cooperating with the locking blocks 10 on the surface of the base 1, a pull plate 12 slidably connected to the surface of the pull rod 6, and fixed blocks 13 fixedly connected to both ends of the pull plate 12, and the front of the fixed shell 5... Two fixing holes 14 are provided on both sides of the end for use with fixing blocks 13. By pulling the pull plate 12 outward, the fixing blocks 13 are disengaged from the fixing holes 14. Pulling the pull rod 6 moves the trapezoidal block 8 upward. The trapezoidal block 8 moves the moving plate 9, causing the locking block 10 to disengage from the slot 11, thereby releasing the fixing between the support column 2 and the circular frame 3. The position of the circular frame 3 can then be adjusted to maintain the distance between each layer. At the same time, through the above process, the height of the multi-layer cultivation rack can be adjusted to ensure that each layer of circular frame 3 receives sufficient sunlight for effective photosynthesis and nutrient absorption, better adapts to environmental conditions at different growth stages, promotes healthy celery growth, and improves planting flexibility.

[0022] Reference Figure 3 As shown in this embodiment: a first spring 15 is slidably connected to the surface of the pull rod 6. One end of the first spring 15 is fixedly connected to the circular plate 7, and the other end of the first spring 15 is fixedly connected to the pull plate 12. By setting the structure of the first spring 15, when the pull rod 6 is fixed, the pull plate 12 is pushed to drive the fixing block 13 to be smoothly inserted into the interior of the fixing hole 14. At this time, the first spring 15 is in a stretched state. When it is necessary to release the fixation of the pull rod 6, the pull plate 12 is pulled outward and the rebound force of the first spring 15 is used to drive the fixing block 13 out of the interior of the fixing hole 14. The operation is simple and convenient.

[0023] Reference Figure 4 As shown in this embodiment: Limiting blocks 16 are fixedly connected to both sides inside the fixed shell 5. The limiting blocks 16 are located on both sides of the trapezoidal block 8. One side of the limiting block 16 is slidably connected to the trapezoidal block 8. By setting the structure of the limiting block 16, the movement path of the trapezoidal block 8 can be restricted, and it plays a role in assisting movement.

[0024] Reference Figure 4 As shown in this embodiment: sliders 17 are fixedly connected to both sides of the movable plate 9, and grooves 18 that cooperate with the sliders 17 are opened on both sides inside the fixed shell 5. By setting the structure of sliders 17 and grooves 18, the movement state of the movable plate 9 is effectively constrained and deviation is prevented.

[0025] Reference Figure 4 As shown in this embodiment: the bottom of the movable plate 9 is fixedly connected to two second springs 19, which are located on both sides of the locking block 10. The other end of the second spring 19 is fixedly connected to the inside of the fixed shell 5. By setting the structure of the second spring 19, when the fixation between the support column 2 and the circular frame 3 is released, the second spring 19 is in a stretched state. After adjusting the distance between the multiple circular frames 3, it is only necessary to pull down the pull rod 6 to drive the trapezoidal block 8 to move. The trapezoidal block 8 drives the movable plate 9 to move towards the support column 2, and uses the rebound force of the second spring 19 to pull the locking block 10 to smoothly insert into the inside of the locking slot 11, thereby realizing the fixation between the support column 2 and the circular frame 3.

[0026] Reference Figure 2 As shown in this embodiment: several cultivation pots 20 are fixedly connected to the surface of the circular frame 3. The cultivation pots 20 are distributed in a circle. Multiple ventilation holes 21 are opened at the bottom of the cultivation pots 20. A water storage layer 22 is set at the bottom of the cultivation pots 20. By setting the structure of the water storage layer 22, the water storage layer 22 can store a certain amount of water to ensure that the soil maintains an appropriate level of moisture, thereby reducing the need for frequent watering. At the same time, the structure of the ventilation holes 21 allows the air inside the cultivation pots 20 to circulate, providing more oxygen to the celery roots, which helps the celery roots to breathe and prevents the roots from rotting due to excessive soil moisture.

[0027] Reference Figure 1 and Figure 5 As shown in this embodiment: a groove 23 is provided on the surface of the circular frame 3, and the groove 23 is located directly below the cultivation pot 20. A drain pipe 24 is fixedly connected to one side of the circular frame 3, and a liquid storage tank 25 is provided below the drain pipe 24. A filter plate 26 is slidably connected inside the liquid storage tank 25. Through the structure of the groove 23, the drain pipe 24 and the liquid storage tank 25, excess nutrient solution and water can be effectively discharged and collected. The collected nutrient solution can be reused after appropriate treatment. This not only reduces resource waste, but also allows us to understand the growth needs and nutritional status of celery by analyzing these nutrient solutions. At the same time, the structure of the filter plate 26 can remove impurities and harmful substances from the nutrient solution and excess water, improve water quality, thereby reducing damage to celery and promoting healthy growth of celery.

[0028] Working principle: By pulling the pull plate 12 outward, the user moves the fixing block 13 out of the fixing hole 14. Pulling the pull rod 6 moves the trapezoidal block 8 upward, which in turn moves the moving plate 9, causing the locking block 10 to disengage from the slot 11. This releases the fixation between the support column 2 and the circular frame 3, allowing for position adjustment of the circular frame 3. The positions of the two circular frames 3 are adjusted to maintain the distance between each layer. Simultaneously, through the above process, the height of the multi-layer cultivation rack can be adjusted, ensuring that each layer of the circular frame 3 receives sufficient sunlight for effective photosynthesis and nutrient absorption, better adapting to environmental conditions at different growth stages and promoting growth. The healthy growth of celery improves planting flexibility. By incorporating the first spring 15, when the pull rod 6 is fixed, the pull plate 12 is pushed, causing the fixing block 13 to smoothly insert into the fixing hole 14. At this time, the first spring 15 is in a stretched state. To release the fixation of the pull rod 6, the pull plate 12 is pulled outwards, and the rebound force of the first spring 15 causes the fixing block 13 to disengage from the fixing hole 14. The operation is simple and convenient. The limiting block 16 restricts the movement path of the trapezoidal block 8 and assists in its movement. The slider 17 and the groove 18 effectively constrain the movement of the moving plate 9, preventing deviation. By setting the structure of the second spring 19, when the fixation between the support column 2 and the circular frame 3 is released, the second spring 19 is in a stretched state. After adjusting the distance between the multiple circular frames 3, it is only necessary to pull down the pull rod 6 to move the trapezoidal block 8. The trapezoidal block 8 moves the moving plate 9 towards the support column 2, and the rebound force of the second spring 19 pulls the locking block 10 to smoothly insert into the slot 11, thereby fixing the support column 2 and the circular frame 3. By setting the structure of the water storage layer 22, the water storage layer 22 can store a certain amount of water to ensure that the soil maintains appropriate moisture, thereby reducing the need for frequent watering. At the same time, the structure of the vent hole 21... The structure allows air circulation inside the cultivation pot 20, providing more oxygen to the celery roots, which helps with root respiration and prevents root rot caused by excessive soil moisture. The structure of groove 23, drainage pipe 24, and liquid storage tank 25 enables the effective discharge and collection of excess nutrient solution and water. The collected nutrient solution can be reused after appropriate treatment, which not only reduces resource waste but also allows for analysis of the nutrient solution to understand the celery's growth needs and nutritional status. At the same time, the structure of filter plate 26 can remove impurities and harmful substances from the nutrient solution and excess water, improving water quality, thereby reducing damage to the celery and promoting its healthy growth.
