Detailed Implementation

[0028] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0029] To address the technical problem in existing agricultural cultivation devices where the cultivation trough is an integrated structure, which prevents effective drainage and respiration of plant roots and stems, leading to root and stem rot, this invention provides a cultivation device for agricultural planting that can improve plant cultivation efficiency while avoiding water waste.

[0030] It should be noted that the cultivation device for agricultural planting described in this utility model is applicable to, but not limited to, the field of agricultural technology. For ease of explanation, this utility model only uses the application of the cultivation device for agricultural planting in the field of agricultural technology as an example for explanation. The principle of the cultivation device for agricultural planting applied to other types of equipment is essentially the same as the principle applied to the field of agricultural technology, and will not be described in detail here.

[0031] Please see Figure 1 , Figure 1 This is a schematic diagram of a cultivation device for agricultural planting according to one embodiment of the present invention. The cultivation device for agricultural planting includes:

[0032] The incubation box 1 includes a box body 2 and a mounting plate 3. The box body 2 is provided with a water storage chamber and the top is detachably connected to the mounting plate 3. Several incubation troughs 31 are provided on the mounting plate 3, and an incubation basin 4 is arranged in any one of the incubation troughs 31.

[0033] The liquid supply mechanism 5 includes a water storage tank 51, a pumping end 52, a supplying end 53, and a spraying end 54. The water storage tank 51 maintains a gap with the tank body 2, and the two ends of the tank body 2 are respectively provided with a pumping end 52 and a supplying end 53 for supplying water to the water storage chamber. The ends of the pumping end 52 and the supplying end 53 away from the tank body 2 are connected to the water storage tank 51 and form a height difference. One end of the spraying end 54 is connected to the water storage tank 51, and the other end extends to the upper end of the mounting plate 3 and is used to spray the material in the cultivation pot 4.

[0034] In this embodiment, by setting up a water storage tank 51 independent of the cultivation box 1, and configuring a liquid supply mechanism 5 consisting of a pumping end 52 and a supply end 53, a highly efficient liquid circulation structure is formed. This structure not only promptly drains excess water, preventing root rot caused by anaerobic respiration due to water accumulation, but also ensures the freshness of the nutrient solution or irrigation water, promoting healthy root growth. The pumping end 52 extracts the old liquid from the box 2 and returns it to the water storage tank 51, while the supply end 53 replenishes the box 2 with fresh liquid, forming a closed loop. This greatly improves the utilization rate of water resources and dissolved fertilizers, reduces waste, and aligns with the development concept of green agriculture. The ends of the pumping end 52 and the supply end 53 furthest from the box 2 are connected. The water storage tank 51 is positioned at a certain height difference to improve the stability and controllability of the entire water supply and drainage process, reduce energy consumption, and extend the service life of the equipment. The cultivation box 1 adopts a detachable connection method, combined with the independently removable cultivation pot 4, so that the entire device has good installation and disassembly functions. Users can easily clean, disinfect or replace each component, effectively preventing residual bacteria and cross-infection, and meeting the needs of continuous seedling cultivation in multiple batches. One end of the spray end 54 is connected to the water storage tank 51, and the other end extends to the top of the mounting plate 3 and is equipped with a spray plate 543. Driven by the third pump body 542, it achieves uniform spraying, simulating the effect of natural rainfall, ensuring that the seedlings receive sufficient and uniform water and nutrient supply, which is conducive to seed germination and healthy seedling growth.

[0035] In one embodiment, please refer to Figure 1 - Figure 5 To facilitate the installation and removal of the mounting plate 3, the upper end of the box 2 is an open structure, and the inner wall of the box 2 is provided with a first extension plate 21. The first extension plate 21 is provided with multiple positioning holes 211. The mounting plate 3 is placed on the first extension plate 21. The end of the mounting plate 3 facing the first extension plate 21 is provided with several positioning posts 300 that cooperate with the positioning holes 211.

[0036] In this embodiment, the first extension plate 21 is arranged circumferentially along the inner wall of the box 2 to form a support platform for supporting the installation plate 3. By opening multiple positioning holes 211 on the first extension plate 21 and setting corresponding positioning posts 300 at the bottom of the installation plate 3, the two form an interlocking structure, which can guide the installation plate 3 to fall accurately into the predetermined position during the installation process, effectively avoiding problems such as misalignment, tilting or eccentricity, and significantly improving the assembly accuracy between the installation plate 3 and the box 2. This ensures that the relative positional relationship between each cultivation tank 31 and the lower water storage chamber remains consistent, providing a basic guarantee for subsequent irrigation, drainage and overall structural stability. After the positioning posts 300 are inserted into the positioning holes 211, they can effectively restrict the degree of freedom of the installation plate 3 in the horizontal direction, preventing it from sliding or shifting due to external forces such as spray impact, manual operation or handling vibration during use. Simultaneously, the first extension plate 21, as a load-bearing structure, evenly transfers the entire weight of the mounting plate 3 and its upper cultivation pot 4, plants, substrate, etc., to the side wall of the box 2, improving the structural strength and load-bearing stability of the entire device and avoiding deformation or damage caused by localized stress concentration. This snap-fit ​​structure eliminates the need for additional fasteners such as screws or clips, enabling the rapid positioning and stable placement of the mounting plate 3. When users change the seedling cycle, clean and disinfect, or replace parts, they can easily remove or reinstall the mounting plate 3 as a whole, making the operation simple, time-saving, and labor-saving, greatly improving the maintainability and flexibility of the device. The upper end of the box 2 has an open structure, which, together with the cover-type installation of the mounting plate 3, physically separates the water storage chamber from the upper cultivation area. The snap-fit ​​structure ensures that the mounting plate 3 is in close contact with the box 2 after it is placed in place.

[0037] In one embodiment, please refer to Figure 1 - Figure 3 To improve the ventilation effect of the box 2, several ventilation holes 22 are provided on the outer wall of the box 2, and multiple guide plates 23 are arranged inside the box 2 and located in the water storage cavity.

[0038] In this embodiment, the ventilation holes 22 on the outer wall of the box 2 enable the communication and exchange of air between the inside and outside of the box 2. Under natural convection or external breeze, fresh air can enter the interior of the box 2 through the ventilation holes 22, especially penetrating to the area above the water storage chamber and the bottom of the cultivation pot 4, effectively increasing the oxygen content in the root zone. Good air permeability helps the plant roots to carry out normal aerobic respiration, avoiding hypoxia, anaerobic fermentation, and root rot caused by long-term water accumulation or a closed environment, significantly improving the survival rate and growth vitality of seedlings. The presence of the ventilation holes 22 has This facilitates moisture removal, reducing the relative humidity inside the container 2, especially above the water storage chamber, and preventing the proliferation of mold, algae, or other harmful microorganisms due to excessive humidity. This plays a crucial role in maintaining a clean and hygienic cultivation environment and reducing the risk of disease transmission. It is particularly suitable for high-density seedling cultivation or long-term continuous operation planting scenarios. Multiple guide plates 23 are installed inside the water storage chamber to effectively guide the flow of liquid within the container 2, preventing "dead water zones." When water is supplied to the water storage chamber by the water supply end 53 or pumped out by the water pump end 52, the guide plates 23 can... The water flow is rationally divided to make the liquid distribution in the cavity more uniform, ensuring that the water level under each cultivation pot 4 is consistent, thereby achieving more balanced water recovery and supply, and improving the stability and reliability of the overall system. The guide plate 23 can reduce the turbulence resistance and energy loss of the liquid during the flow process, and improve the transmission efficiency of the liquid between the pump end 52 and the supply end 53. This not only helps to improve the working efficiency of the first pump body 522 and the second pump body 532, but also extends the service life of the equipment to a certain extent. The ventilation hole 22 and the guide plate 23 work together to form a synergistic cooperation of gas flow and liquid guidance. Ventilation promotes gas exchange, and guidance optimizes liquid distribution. The two complement each other and work together to maintain the dynamic balance of the root zone environment. For example, after sprinkler irrigation, excess water is quickly discharged into the water storage chamber and guided evenly by the guide plate 23. At the same time, the ventilation hole 22 accelerates the discharge of moisture, avoiding local water accumulation and stuffy environment, and providing plants with an ideal growth microenvironment with suitable humidity and good ventilation. The back of the water storage tank 51 is equipped with a water inlet and a water outlet for adding nutrient solution or discharging.

[0039] In one embodiment, please refer to Figure 1 - Figure 3To improve plant cultivation efficiency, the cultivation trough 31 includes several first troughs 311 and several second troughs 312. The first troughs 311 are regular hexagonal troughs and are equidistantly arranged on the mounting plate 3. A second trough 312 is provided between each adjacent first trough 311, and the second trough 312 is octagonal. The bottom of the first troughs 311 and the second troughs 312 are detachably equipped with mesh panels. The inner walls of the first troughs 311 and the second troughs 312 are also provided with second extension plates 313. The cultivation pot 4 includes several first pots 41 corresponding to the first troughs 311 and several second pots 42 corresponding to the second troughs 312. The bottom of the first pots 41 and the second pots 42 are provided with water filter holes 43. The outer walls of the first pots 41 and the second pots 42 are provided with extension plates 313 that cooperate with the second extension plates 313. The third extension plate 44 has symmetrically arranged lifting plates 441. A filter screen 511 is arranged inside the water storage tank 51 and below the water pumping end 52. The water pumping end 52 includes a water pumping pipe 521 and a first pump body 522. The water pumping pipe 521 is used to connect the tank 2 and the water storage tank 51, and the first pump body 522 is installed on the water pumping pipe 521. The water supply end 53 includes a water supply pipe 531 and a second pump body 532. The water supply pipe 531 is used to connect the tank 2 and the water storage tank 51, and the second pump body 532 is installed on the water supply pipe 531. The spraying end 54 includes a spraying pipe 541, a third pump body 542 and a spraying disc 543. One end of the spraying pipe 541 is connected to the water storage tank 51, and the other end extends to the top of the mounting plate 3. The end of the spraying pipe 541 is connected to the spraying disc 543, and the third pump body 542 is installed on the spraying pipe 541.

[0040] In this embodiment, the cultivation trough 31 includes several equidistantly arranged regular hexagonal first troughs 311, and octagonal second troughs 312 are arranged between adjacent first troughs 311, forming a honeycomb-like densely packed structure. Regular hexagons have the geometric advantage of being the most compact arrangement with the smallest gaps in a plane, maximizing the utilization of the mounting plate 3 area and increasing the seedling density per unit area. Simultaneously, the introduction of the octagonal second troughs 312 fully utilizes the natural gaps between the regular hexagons, achieving effective space utilization and further increasing planting capacity. This significantly improves the space utilization efficiency and unit output rate of the device. The bottoms of the first troughs 311 and the second troughs 312 are equipped with... The mesh plate is disassembled and, in conjunction with the filter holes 43 at the bottom of the cultivation pot 4, forms a double drainage structure. The mesh plate acts as a primary filtration layer to prevent substrate loss with water, while the filter holes 43 at the bottom of the cultivation pot 4 allow excess water to drain quickly into the water storage chamber, preventing long-term root soaking. The detachable design facilitates regular cleaning or replacement of the mesh plate, preventing blockage and ensuring long-term unobstructed drainage. This effectively solves the problems of poor drainage, water accumulation, and root hypoxia in traditional integrated cultivation troughs 31, significantly improving the aeration and drainage performance of the plant root zone, which is beneficial to healthy root development. The inner walls of the first trough 311 and the second trough 312 are provided with second extension plates 313, while the corresponding first pot 41 and the second... The outer wall of the second pot body 42 is provided with a third extension plate 44 that cooperates with it. When the cultivation pot 4 is placed into the cultivation trough 31, the third extension plate 44 overlaps with the second extension plate 313 to form a suspended support structure, so that a certain gap is maintained between the bottom of the cultivation pot 4 and the mesh plate, avoiding the bottom of the cultivation pot 4 from directly sticking to the mesh plate and causing blockage. This ensures that the filter holes 43 always effectively drain water, forming an "air gap layer" to enhance air circulation in the root area and further improve the root respiration efficiency. At the same time, it can provide stable support to prevent the cultivation pot 4 from sinking or tilting during transportation or spraying, thus improving the structural reliability. The third extension plate 44 is symmetrically provided with lifting plates 441, which can be lifted by the user with their fingers or tools. By pinching the lifting plate 441, the cultivation pot 4 can be easily and vertically removed from the cultivation tank 31, enabling independent replacement, inspection, or transplanting of a single pot without disassembling the entire mounting plate 3. This facilitates observation of root growth, timely detection of diseases or abnormal growth, reduces manual labor intensity, and improves seedling operation efficiency, making it particularly suitable for large-scale seedling production. A filter screen 511 is installed inside the water storage tank 51 and below the water pump end 52 to intercept impurities such as algae, substrate particles, and plant residues that may be carried in the nutrient solution returning from the tank 2 to the water storage tank 51. The first pump 522 controls the return liquid rate and adjusts the liquid level in the water storage chamber; the second pump 532 controls the replenishment flow rate to maintain the nutrient solution supply.The third pump body 542 independently controls the spray intensity and frequency, enabling on-demand irrigation and adapting to the water and fertilizer needs of different crops and growth stages. Furthermore, the pumping pipe 521, water supply pipe 531, and spray pipe 541 are independently configured to avoid cross-interference, ensuring independent controllability of each functional module and improving equipment operating accuracy and reliability. The spray disc 543 has an atomizing structure, which, driven by the third pump body 542, can evenly atomize or spray the nutrient solution onto the surface of all cultivation pots 4, providing wide coverage without any dead spots. Simultaneously, the small water droplets reduce mechanical impact on seedlings, simulating natural rainfall and promoting leaf absorption and substrate wetting.

[0041] To better understand this utility model, the following is combined with... Figures 1 to 8The technical solution of this utility model is described in detail as follows: Several first pots 41 and second pots 42 are respectively placed into the first trough 311 and the second trough 312 on the mounting plate 3. The third extension plate 44 of the outer wall of the cultivation pot 4 overlaps with the second extension plate 313 of the inner wall of the trough, forming a suspended support structure, so that a certain gap is maintained between the bottom of the pot and the detachable mesh plate to ensure smooth drainage. A suitable seedling substrate (such as peat moss, vermiculite or coconut coir) is filled into each cultivation pot 4, and seeds are sown or seedlings are transplanted. The mounting plate 3 with the cultivation pots 4 assembled is aligned with the top opening of the box 2, so that the positioning post 300 at the bottom of the mounting plate 3 is inserted into the positioning hole 211 on the first extension plate 21 of the inner wall of the box 2, so as to achieve fast and accurate positioning. For positioning and stable support, the mounting plate 3 and the box 2 are tightly connected by a snap-fit ​​structure, forming a physical separation between the upper cultivation area and the lower water storage chamber. The water pump pipe 521, water supply pipe 531, and spray pipe 541 are respectively connected to the box 2 and the water storage tank 51, with the ends of all three connected to the independently set water storage tank 51, forming a certain height difference. Pre-prepared nutrient solution or clean water is injected into the water storage tank 51, and the liquid level should meet the normal operating requirements of the pump. The third pump 542 of the spray end 54 is activated, and the nutrient solution in the water storage tank 51 is transported through the spray pipe 541 to the spray plate 543 above the mounting plate 3. The spray plate 543 adopts an atomizing porous distribution structure to evenly spray the liquid onto the surface of all cultivation pots 4. Simulating natural rainfall, the spraying wets the substrate and supplies the plants with the necessary water and nutrients. The spraying time and frequency can be set according to the crop type and growth stage. After spraying, excess water that is not absorbed by the substrate carries some dissolved nutrients and is discharged through the filter holes 43 at the bottom of the cultivation pot 4. It then passes through the lower mesh plate and enters the water storage chamber inside the box 2. Because the bottom of the cultivation pot 4 is supported on the second extension plate 313 by the third extension plate 44, an "air gap layer" is formed, which prevents the filter holes 43 from being blocked and ensures smooth drainage. When the liquid level in the water storage chamber reaches the set height, the first pump 522 of the pumping end 52 is activated, and the return liquid in the water storage chamber is pumped back to the water storage tank 51 through the pumping pipe 521. The filter screen 511 is set below the inlet of the pumping pipe 521. It can effectively intercept impurities in the liquid, such as algae, substrate particles, and plant residues. According to the consumption of nutrient solution, the second pump 532 of the water supply end 53 is started, and the fresh nutrient solution in the water storage tank 51 is re-injected into the water storage chamber of the box 2 through the water supply pipe 531 to maintain the total liquid balance in the system. When the injected liquid flows in the water storage chamber, it is guided by multiple guide plates 23 to avoid the formation of "dead water zone" and ensure that the liquid is evenly distributed in the box 2, maintain the water level under each cultivation pot 4, and improve the system's water supply and drainage balance. Several ventilation holes 22 opened on the outer wall of the box 2 realize natural air convection inside and outside. Fresh air enters the interior of the box 2 through the ventilation holes 22, promotes oxygen supply in the root zone, and supports aerobic respiration of the roots.Simultaneously, moisture is expelled with the airflow, reducing humidity inside the box, inhibiting the growth of harmful microorganisms such as mold and algae, and maintaining a clean and hygienic cultivation environment. The first pump 522 is used for water extraction, the second pump 532 for water supply, and the third pump 542 for spraying; all can be independently started, stopped, and adjusted to achieve on-demand nutrient solution supply and segmented control. For example, the spraying frequency can be increased during the day when there is sufficient sunlight, and the water supply can be reduced at night to prevent water accumulation. Regular water circulation is activated to refresh the nutrient solution concentration. During seedling cultivation, any cultivation pot 4 can be easily and vertically removed by applying symmetrical force through the lifting plate 441, facilitating observation of root development, replacement of weak or diseased seedlings, or staged transplanting without disassembling the entire mounting plate 3, making operation convenient and efficient.

[0042] The specific embodiments of this utility model described above do not constitute a limitation on the scope of protection of this utility model. Any other corresponding changes and modifications made based on the technical concept of this utility model should be included within the scope of protection of the claims of this utility model.
