Description

Technical Field

[0001] This utility model relates to the field of cultivation and planting technology, and specifically to a cultivation and planting device. Background Technology

[0002] In today's rapidly developing agricultural industry, modern agricultural technology is undergoing profound changes. Among these advancements, soilless cultivation, as a highly efficient, environmentally friendly, and resource-efficient planting method, is receiving increasing attention and becoming more widespread. This planting model breaks free from the constraints of traditional soil, providing more precise and controllable environmental conditions for plant growth, thus placing new and stringent demands on the overall performance of cultivation and planting equipment.

[0003] However, upon examining the various existing planting devices, it is not difficult to find that they have obvious limitations in several key aspects, which seriously restrict the realization of large-scale, high-efficiency planting operations.

[0004] First, the spatial layout design of planting trays has not yet reached an ideal state. The structure and arrangement of traditional planting trays have failed to fully consider the maximization of planting space, resulting in a large number of idle or inefficiently used areas. This not only wastes valuable planting site resources but also limits the number of plants that can be planted per unit area, fundamentally restricting the expansion of planting scale and the improvement of production efficiency, making it difficult to meet the urgent needs of modern agriculture for land productivity.

[0005] Secondly, regarding the nutrient solution supply system, existing devices often fail to ensure the uniform distribution of nutrient solution within the planting area. Due to the lack of a scientifically sound circulation design and precise flow control mechanism, the concentration and flow rate of the nutrient solution vary significantly at different planting locations. This makes it difficult for plants to obtain a balanced and stable supply of nutrients, leading to inconsistent growth rates, uneven plant morphology and quality, and other problems. This directly affects crop yield and quality, weakening the economic benefits and market competitiveness of agricultural production.

[0006] Furthermore, the level of automation in the planting process urgently needs improvement. Existing planting equipment largely relies on manual labor for tasks such as moving and repositioning planting trays and routine management. This method is not only inefficient, but also leads to a sharp increase in labor costs as the scale of planting expands. It also presents problems such as increased risk of plant damage due to the instability and error inherent in manual operation, significantly hindering the advancement of agricultural production towards large-scale and intelligent operations, and failing to meet the inherent requirements of modern agricultural production for efficient and precise management.

[0007] In conclusion, in order to promote the sustainable development of modern agricultural planting industry and break through the technical bottlenecks of existing planting devices, it is urgent to develop a new type of cultivation and planting device that can comprehensively improve the uniformity of nutrient solution supply, optimize the space utilization efficiency of planting trays, and significantly enhance the automation of the planting process. This has extremely important practical significance and broad market application prospects. Utility Model Content

[0031] like Figure 1 and Figure 2As shown, a cultivation and planting device includes a planting rack 1 with several layers of planting areas. A first conveying mechanism 2 extends along the length of the planting rack 1 within each planting area, and a planting tray 3 is provided on the first conveying mechanism 2. A transport rack 4 is provided at one or both ends of the planting rack 1, and a plurality of second conveying mechanisms 5 corresponding to the first conveying mechanism 2 are provided on the transport rack 4. When the transport rack 4 is connected to the planting rack 1, the first conveying mechanism 2 and the second conveying mechanism 5 cooperate to transport the planting tray 3 in the transport rack 4 into the planting rack 1, or to transport the planting tray 3 in the planting rack 1 into the transport rack 4, or to transport the planting tray 3 in the planting rack 1 from one end of the planting rack 1 to the transport rack 4 at the other end. The first conveying mechanism 2 includes two parallel transmission tracks 6 and a plurality of transmission roller groups arranged on the transmission tracks 6. The transmission roller groups include transmission rollers 7 symmetrically arranged on the two parallel transmission tracks 6. Adjacent transmission rollers 7 on the same transmission track 6 are connected by a transmission belt, and the transmission rollers 7 symmetrically arranged on the two parallel transmission tracks 6 are connected by transmission rollers 8. The planting rack 1 is equipped with a drive motor that is driven and connected to a transmission roller 8 and drives the transmission rollers 7 on the transmission track 6 to rotate synchronously through a transmission belt. The second conveying mechanism 5 includes two parallel conveying tracks 9 and driven roller groups arranged at both ends of the conveying tracks 9. The driven roller groups include driven rollers 10 symmetrically arranged on the two parallel conveying tracks 9. Adjacent driven rollers 10 on the same conveying track 9 are connected by a transmission belt, and the driven rollers 10 symmetrically arranged on the two parallel conveying tracks 9 are connected by driven rollers 11. When it is necessary to transport the planting tray 3 from the transport rack 4 to the planting rack 1, the transport rack 4 is first moved to the docking position of the planting rack 1, so that the second conveying mechanism 5 on the transport rack 4 is precisely aligned with the first conveying mechanism 2 of the planting rack 1. Then, the drive motor of the planting rack 1 is started, and the power is transmitted to the transmission roller 7 through the transmission roller 8 and the transmission belt. Driven by the transmission belt, the planting tray 3 is smoothly transferred from the transport rack 4 to the planting area of ​​the planting rack 1. The transport rack is moved by the transport trolley 35. When it is necessary to move the transport rack, the transport trolley 35 is controlled to move to the bottom of the transport rack. The transport trolley 35 lifts the transport rack from the bottom through the lifting platform, and then drives the transport rack to move, thereby realizing the displacement of the transport rack. Through the above structural design, the cultivation and planting device of this application realizes the efficient and stable transportation of the planting tray 3 between the planting rack 1 and the transport rack 4, which greatly improves the production efficiency and automation level of agricultural planting, reduces manual intervention and labor intensity, and provides strong technical support for modern agricultural production. Example

[0032] like Figure 2As shown, the first conveying mechanism 2 and the second conveying mechanism 5 are drivenly connected by a transmission mechanism 12. The transmission mechanism 12 includes a transmission rod 13 and a first transmission gear set 14 and a second transmission gear set 15, which are respectively drivenly connected to the first conveying mechanism 2 and the second conveying mechanism 5, respectively. One end of the transmission rod 13 is connected to the second transmission gear set 15, and the other end is drivenly connected to the first transmission gear set 14 through a plug-in assembly. The plug-in assembly includes a male plug-in socket 16 and a female plug-in socket 17 respectively disposed on the transmission rod 13 and the first transmission gear set 14. Specifically, one end of the transmission rod 13 is connected to the second transmission gear set 15. The second transmission gear set 15 includes a driving gear disposed on the transmission rod 13 and a driven gear disposed on the second conveying mechanism 5. The driving gear and the driven gear mesh with each other for transmission. At the other end of the transmission rod 13, there is a plug-in assembly for connecting with the first transmission gear set 14. The plug-in male seat 16 on the first transmission gear set 14 is provided with a positioning boss, and the plug-in female seat 17 of the transmission rod 13 is a positioning groove that matches the plug-in male seat 16. When the transport frame 4 needs to connect the transmission rod 13 and the first transmission gear set 14 to dock with the planting frame 1, the end of the first transmission gear set 14 with the plug-in male seat 16 is aligned with the plug-in female seat 17 of the transmission rod 13, so that the positioning boss is aligned with the positioning groove. Then, the second transport mechanism 5 is driven to work synchronously by driving the first transport mechanism 2.

[0033] The working principle is as follows: When the drive motor of the planting rack 1 starts, the power first drives the transmission roller 8 to transmit power to the first transmission gear set 14. The first transmission gear set 14 transmits power through gear meshing. Since the transmission rod 13 is connected to the first transmission gear set 14 through a plug-in assembly, the rotation of the first transmission gear set 14 will drive the transmission rod 13 to rotate synchronously. The rotation of the transmission rod 13 will then transmit power to the second transmission gear set 15 connected to its other end. The second transmission gear set 15 then drives the second conveying mechanism 5 on the transport rack 4 to operate.

[0034] During the docking process between the transport frame 4 and the planting frame 1, as they gradually approach each other, the transmission rod 13 automatically and precisely connects with the first transmission gear set 14 without requiring any additional complex operations. When the transport frame 4 needs to move away from the planting frame 1, the transmission rod 13 can also be easily detached from the first transmission gear set 14 without obstructing the movement of the transport frame 4. This transmission mechanism 12 effectively realizes the power transmission between the planting frame 1 and the transport frame 4, ensuring efficient and stable transportation of the planting tray 3 between the two without the need for a separate drive motor, greatly improving the automation level and working efficiency of the entire cultivation and planting device. Example

[0035] like Figure 3 and Figure 4As shown, the planting rack 1 has a liquid circulation system on both sides of the planting tray 3. The liquid circulation system includes a storage tank, a circulation pump, a liquid delivery pipe 18, and a liquid return pipe 19. The planting tray 3 has a liquid delivery port 20 and a liquid discharge port 21. The liquid delivery pipe 18 is connected to the liquid delivery port 20 on the planting tray 3 through a branch port. One end of the liquid return pipe 19 is connected to a liquid collection tank 22 at the position corresponding to the liquid discharge port 21, and the other end is connected to the storage tank. When the planting tray 3 is draining liquid, the liquid in the planting tray 3 flows out of the liquid discharge port 21 to the liquid collection tank 22 for collection, and the liquid is transported to the storage tank for storage through the liquid return pipe 19 connected to the liquid collection tank 22. The storage tank is connected to the circulation pump to supply the liquid to the liquid delivery pipe 18 to achieve circulation.

[0036] The storage tank is placed at the bottom of the planting rack 1 for easy storage and management of the nutrient solution. A centrifugal pump with a flow rate of 100 L / h and a head of 10 meters is preferred for circulation, providing sufficient power to circulate the nutrient solution within the system. Both the infusion pipe 18 and the return pipe 19 are made of PVC with smooth inner walls to reduce flow resistance and a diameter of 20 mm to ensure a stable flow rate of the nutrient solution.

[0037] During the nutrient solution circulation process, the circulation pump is activated, and the nutrient solution in the storage tank is delivered to the infusion port 20 above the planting tray 3 through a branch of the infusion pipe 18. The infusion port 20 is funnel-shaped. The nutrient solution flows evenly into the storage chamber 27 in the planting tray 3 through the infusion port 20, providing nutrients to the plant roots. When the nutrient solution in the planting tray 3 reaches a certain level, the excess nutrient solution flows out through the drain port 21 of the planting hole 28 to the collection tank 22, and then flows back to the storage tank through the return pipe 19, realizing the recycling of the nutrient solution. By periodically testing the concentration and pH of the nutrient solution, nutrient solution can be added or the pH adjusted according to the plant growth, ensuring that the plants are always in a suitable growth environment. Example

[0038] like Figure 1 and Figure 5As shown, a magnetic docking device is provided between the planting rack 1 and the transport rack 4. The magnetic docking device includes a magnet 23 and a magnetic block 24 located at the docking point of the transport rack 4 and the planting rack 1. The magnetic docking device is also equipped with a sensing device, which includes an infrared sensor or a proximity switch located at the docking point of the transport rack 4 and the planting rack 1. When it is necessary to transport the planting tray 3 in the transport rack 4 to the planting rack 1, the operator or the transport trolley 35 first transports the transport rack 4 to the docking position of the planting rack 1. The magnet 23 and the magnetic block 24 in the magnetic docking device are magnetically attracted and fixed to each other, so that the transport rack 4 and the planting rack 1 are quickly and accurately docked. At the same time, the infrared sensor of the sensing device monitors the position of the transport rack 4 in real time. When the transport rack 4 is driven into the sensing range (within 10 cm of the docking point of the planting rack 1) by the transport trolley 35, the infrared sensor sends a signal to the transport trolley 35, controlling the transport trolley 35 to drive the transport rack 4 to fit tightly against the planting rack 1.

[0039] like Figure 6 As shown, the planting tray 3 includes an outer planting tray 25 and an inner planting tray 26, with a liquid storage cavity 27 formed between the outer planting tray 25 and the inner planting tray 26 for storing liquid. The inner planting tray 26 is evenly provided with a plurality of planting holes 28 that communicate with the liquid storage cavity 27. The planting holes 28 are used to place plant cultivation boxes. The bottom of the plant cultivation boxes is provided with through holes to facilitate the extension of plant roots into the liquid storage cavity 27 for absorbing nutrients. The inner planting tray 26 is provided with a plurality of drainage grooves 29 around the planting holes 28. The inner planting tray 26 is also provided with a liquid collection hole 30 that communicates with the liquid storage cavity 27. The liquid collection hole 30 is located at the intersection of adjacent drainage grooves 29. Example

[0040] like Figure 7 As shown, in order to effectively reduce the weight of the planting tray 3, reduce the difficulty and risk of transportation, and at the same time avoid the leakage of liquid in the planting tray 3 from affecting the surrounding environment, the first conveying mechanism 2 of the planting rack 1 is provided with a tilting device at at least one end. The tilting device includes a tilting platform 31 set below the first conveying mechanism 2. One end of the tilting platform 31 is movably hinged to the planting rack 1, and the bottom of the other end is hinged with a support cross rod. The support cross rod includes a support long rod 32 and a support short rod 33. The bottom of the support long rod 32 is provided with a pulley and a slide rail. The support long rod 32 drives the pulley of the support rod to slide back and forth along the slide rail through a sliding cylinder.

[0041] When it is necessary to tilt the planting tray 3 for drainage, the planting tray 3 is transported to the tilting device position via the first conveying mechanism 2. The sliding cylinder is activated, and the piston rod of the sliding cylinder extends, driving the pulley of the support rod 32 to slide forward along the slide rail, changing the angle of the support cross rod, thereby lifting one end of the tilting platform 31 to form a tilt angle of 15 to 45 degrees. At this time, the excess water or nutrient solution in the planting tray 3 flows out through the drain port 21 of the planting tray 3 to the collection tank 22 at one end of the return pipe 19 under the action of gravity, thereby reducing the weight of the planting tray 3 and preventing the nutrient solution from leaking during transportation and affecting the surrounding environment. The collection tank 22 can effectively collect the drained nutrient solution, and the liquid is transported to the storage tank through the return pipe 19 for storage, which is convenient for subsequent transportation and operation. Example

[0042] like Figure 3 As shown, to provide suitable light conditions for plant growth, the planting rack 1 is also equipped with a lighting system, including multiple LED plant growth lights correspondingly set above the planting trays 3. The LED plant growth lights 34 are full-spectrum LED lamps, which can simulate the spectral distribution of natural sunlight and provide plants with light of different wavelengths from blue light to red light to meet the needs of different growth stages of plants. Four LED plant growth lights are evenly set above each planting tray 3. The power of the LED plant growth lights is preferably 30W, with high luminous efficiency.

[0043] During the seedling stage, the LED plant grow lights are set to a light intensity of 2000 lux and a light duration of 16 hours per day to promote photosynthesis and growth, resulting in robust seedling development. As the plants enter their growth period, the light intensity is gradually increased to 3000 lux, and the light duration is adjusted to 14 hours per day to meet the plants' higher light requirements. During the flowering and fruiting stages, the light spectrum and intensity are further optimized based on the characteristics of different plants, such as increasing the proportion of red light to promote flower bud differentiation and fruit development. Therefore, by implementing a lighting system, the growth rate, quality, and yield of plants can be significantly improved, providing strong support for agricultural planting.

[0044] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
