[0023] The following will describe in detail the implementation of this application with reference to the accompanying drawings and embodiments, so that the implementation process of how this application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0024] Figures 1-4 As an embodiment of this utility model, a soilless vegetable planting rack includes a support 1. The side surface of the support 1 is provided with a plurality of holes at equal intervals from top to bottom. A limiting component 2 is fitted inside the holes. A plurality of cultivation components 3 are snapped onto the surface of the support 1 by the limiting component 2.

[0025] The specific problem addressed in this embodiment is to solve the issue of nutrient solution contamination caused by floating dust or small flying insects settling on the surface during vegetable cultivation, and the lack of a structured filtration system for the nutrient solution. This invention utilizes drain pipes 34 and inlet pipes 35 located on both sides of the cultivation tank 32, along with a series-connected circulation pump 36 and filter pipe 37. This allows the nutrient solution to be driven by the circulation pump 36 from the drain pipe 34 into the filter pipe 37, and then sequentially pass through a coarse filter screen 38, filter cotton 39, and a gravel layer 310 for three-stage filtration. This effectively removes floating dust, insects, and suspended particles, preventing nutrient solution contamination, extending its service life, and reducing replacement frequency.

[0026] The culture component 3 includes a base plate 31 disposed on the surface of the support 1. A culture tank 32 is fixedly connected to the top surface of the base plate 31. A cover plate 33 is magnetically connected to the top surface of the culture tank 32. Through openings are provided on both sides of the culture tank 32 and a drain pipe 34 and a water inlet pipe 35 are fixedly connected to them respectively. The drain pipe 34 is connected to a circulation pump 36. The circulation pump 36 is connected to the water inlet pipe 35 through a filter pipe 37. The filter pipe 37 is fitted with a coarse filter screen 38, a filter cotton 39 and a gravel layer 310. In this specific embodiment, the cover plate 33 covers the opening on the top surface of the culture tank 32 and the magnetic surface matches the shape of the edge of the culture tank 32. The base plate 31 of the cultivation component 3 is fixed to the surface of the support 1 by engaging with the locking bead 22 of the limiting component 2 through the side wall locking holes. A cultivation tank 32 is welded to the top surface of the base plate 31. A magnetic strip is embedded in the edge of the top opening of the cultivation tank 32 and is attached to the bottom edge of the cover plate 33 by magnetic attraction. The cover plate 33 is made of transparent acrylic material and has an array of ventilation holes on its surface to adapt to the ventilation requirements of different sized cultivation pots. Through openings are opened on both sides of the cultivation tank 32 and a drain pipe 34 and a water inlet pipe 35 are welded thereon. The drain pipe 34 is connected to the circulation pump 36 through a flange. The inlet end is sealed and connected. The output end of the circulation pump 36 is fixed to the filter tube 37 by a clamp. Inside the filter tube 37, a coarse filter screen 38, a filter cotton 39, and a gravel layer 310 are pressed in sequence along the liquid flow direction. The coarse filter screen 38 has a pore size of 2-3 mm to intercept large particles of impurities. The filter cotton 39 is 10 mm thick to adsorb suspended solids. The gravel layer 310 is filled with quartz sand with a particle size of 1-2 mm to form a deep filtration structure. The end of the water inlet pipe 35 extends to the bottom of the culture tank 32 and forms a liquid flow buffer channel through an elbow to reduce the impact of nutrient solution backflow.

[0027] In this specific embodiment, the limiting component 2 includes a spring 21 sleeved inside the sleeve hole, a locking bead 22 fixedly connected to the side of the spring 21, and a pull rod 23 fixedly connected to one end of the locking bead 22.

[0028] The spring 21 of the limiting component 2 is sleeved inside the sleeve hole of the bracket 1. The side of the spring 21 is fixedly connected to the locking bead 22. The end of the locking bead 22 away from the spring 21 is welded to the pull rod 23 and the locking bead 22 is exposed outside the sleeve hole. The pull rod 23 extends through the sleeve hole to the other side surface of the bracket 1. When the pull rod 23 is pulled outward, it causes the locking bead 22 to compress the spring 21 and disengage from the locking hole of the base plate 31, thereby realizing the disassembly or height adjustment of the culture component 3. The end of the locking bead 22 is a hemispherical protrusion structure that matches the concave contour of the inner wall of the locking hole of the base plate 31. When the spring 21 is reset, the locking bead 22 is embedded in the locking hole to form a locking fixation.

[0029] Working principle: The limiting component 2 of the support 1 uses the elastic force of the spring 21 to fix the card 22 into the card hole of the bottom plate 31 of the cultivation component 3. When it is necessary to adjust the height of the cultivation component 3, pull the pull rod 23 outward to drive the card 22 to compress the spring 21 and disengage it from the card hole. At this time, the cultivation component 3 can be moved up and down along the sleeve hole of the support 1 to the target position. Then, release the pull rod 23, and the spring 21 will reset and push the card 22 to re-enter the new card hole of the bottom plate 31 to complete the positioning. The nutrient solution in the cultivation tank 32 is drawn to the filter pipe 37 by the circulation pump 36 through the drain pipe 34. After passing through the coarse filter screen 38 to intercept large particles of impurities, the filter cotton 39 to adsorb suspended matter, and the gravel layer 310 for deep filtration, the purified nutrient solution flows back to the cultivation tank 32 through the water inlet pipe 35 to form a circulation purification system. The magnetically connected cover plate 33 can be opened and closed easily to place or adjust the cultivation pot. Its transparent material makes it easy to observe the growth status of vegetables, and the surface vents ensure ventilation.
