Description

Technical Field

[0002] Seedling cultivation is a fundamental step in agricultural and horticultural production. It is the process of cultivating plant seeds, tubers, and branches into robust seedlings through scientific methods. The core objective is to provide high-quality seedlings with high survival rates and good growth for subsequent planting, which directly affects the final yield and quality of crops. Nowadays, with the development of technology, efficient methods such as plug seedling cultivation and tissue culture are gradually becoming more widespread. This not only improves seedling cultivation efficiency but also enables standardized and large-scale production of seedlings, laying an important foundation for precision planting in modern agriculture.

[0003] In the early stages, after selecting suitable cultivation trays based on experience, the prepared seedling substrate was manually filled into the holes of the trays. The substrate was mostly ordinary garden soil mixed with some organic fertilizer. The filling process was entirely manual, and the control over the uniformity and compaction of the filling was not precise. Seeds were also sown manually in each hole, resulting in a large amount of seeds and poor distribution. Nowadays, seedling companies use mechanized equipment for substrate filling, which is fast and the filling amount is consistent, which can effectively improve work efficiency. The sowing process is equipped with precision seeders, which can accurately control the number of seeds sown in each hole and greatly reduce seed waste. However, in subsequent management, watering still relies on manual hand-held sprayers, which makes it difficult to ensure that the seedlings receive adequate water. Utility Model Content

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Please see the appendix Figure 1 - Appendix Figure 3An embodiment of this utility model is provided: an automatic irrigation seedling cultivation tray, including a support 1, a cultivation tray mechanism 2 is provided between two adjacent supports 1, the cultivation tray mechanism 2 is used to cultivate seedlings, and an automatic irrigation mechanism 3 is provided on the top of the support 1, the automatic irrigation mechanism 3 is used for automatic irrigation.

[0033] The cultivation tray mechanism 2 includes a slide rail 201, which is fixed to the inner wall of the support 1. A slider 202 is slidably connected to the inner wall of the slide rail 201. A rigid component 203 is provided between two adjacent sliders 202. A soft component 204 is provided on the top surface of the rigid component 203. A plurality of overflow holes 206 are opened on the bottom surface of the rigid component 203. A locking block 205 is slidably connected to the inner wall of the support 1. A reset component 207 is provided at one end of the locking block 205.

[0034] Specifically, the support frame 1 serves as the basic support component of the entire cultivation tray, used to fix and support all components, ensuring the stability of the overall structure. It also provides reasonable installation positions for each component, creating a layered structure within the cultivation tray and improving space utilization. A cultivation tray mechanism 2 is located between two adjacent supports 1, specifically for placing seedlings and providing a basic environment for their growth, enabling centralized cultivation and management. The cultivation tray mechanism 2 is used for seedling cultivation. An automatic irrigation mechanism 3 is installed at the top of the support frame 1 to automatically provide water to the seedlings in the cultivation tray mechanism 2, eliminating the need for frequent manual watering and automating the irrigation process. This ensures timely and uniform water supply to the seedlings. The cultivation tray mechanism 2 includes a slide rail 201 fixed to the inner wall of the support frame 1, providing a sliding track for the slider 202. This allows the slider 202 to move stably along the slide rail 201, thereby driving the rigid component 203 to perform a pulling action. This facilitates the handling of seedlings and the maintenance of the seedlings, enhancing the ease of use of the cultivation tray. The rigid component 203 serves as the rigid support structure of the cultivation tray mechanism 2, supporting the soft component 204 and the seedlings. It prevents the soft component 204 from deforming due to the weight of the seedlings or soaking in water. The soft component 204 is in direct contact with the seedlings, providing them with the necessary nutrient carrier and buffer environment for growth. The bottom surface of the rigid component 203 has multiple overflow holes 206. When there is too much water in the soft component 204, the excess water can be discharged through the overflow holes 206, preventing the roots of the seedlings from rotting due to water accumulation and ensuring that the humidity of the seedling growth environment is within a suitable range. The inner wall of the support 1 is slidably connected to a locking block 205, which can slide on the inner wall of the support 1. When the rigid component 203 slides into the designated position of the support 1 via the slider 202, the locking block 205 can lock the slider 202 and the rigid component 203, preventing them from accidentally sliding due to external force collisions during use and ensuring the stability of the cultivation tray mechanism 2. One end of the locking block 205 is provided with a reset component 207, which provides reset power for the locking block 205.

[0035] Please see the appendix Figure 4 - Appendix Figure 5 The automatic irrigation mechanism 3 includes a water storage tank 301, which is fixed to the top of the support 1. A guide component 302 is provided at the bottom of the water storage tank 301. Multiple watering components 303 are provided at the bottom of the guide component 302. Multiple inclined plates 304 are fixedly connected to the inner wall of the support 1. Multiple guide grooves 305 are opened at the top of the inclined plates 304. A recycling groove 306 is provided at the bottom of the support 1.

[0036] Specifically, the automatic irrigation mechanism 3 includes a water storage tank 301 for storing irrigation water, providing a water source reserve for automatic irrigation and reducing the frequency of water addition. Nutrient solution can be added to the water as needed to achieve integrated water and fertilizer irrigation. The water storage tank 301 is fixed to the top of the support 1. A guiding component 302 is installed at the bottom of the water storage tank 301 to guide the water in the water storage tank 301 to each irrigation component 303, playing a role in water transport and distribution, ensuring that water is evenly distributed to each irrigation component 303. Multiple irrigation components 303 are installed at the bottom of the guiding component 302 to directly irrigate the seedlings in the cultivation tray mechanism 2, delivering the water from the guiding component 302 to the roots of the seedlings in a suitable manner, ensuring the accuracy and uniformity of irrigation. The inner wall of the support 1... Multiple inclined plates 304 are fixedly connected to fix the irrigation component 303, providing stable installation support for the irrigation component 303, preventing the irrigation component 303 from shaking, and can collect excess water dripping during the irrigation process. The water is guided to the recycling tank 306 through the guide groove 305 to reduce water waste. The top of the inclined plate 304 has multiple guide grooves 305 with an inclined design, which can concentrate the excess water collected on the inclined plate 304 to the recycling tank 306, avoiding water dripping randomly and contaminating the bottom of the support 1, thus achieving orderly water recycling. The bottom of the support 1 is provided with a recycling tank 306 to collect excess water transported by the inclined plate 304 through the guide groove 305, realizing the recycling and reuse of irrigation water, reducing water consumption, and keeping the bottom environment of the cultivation tray dry and clean.

[0037] Please see the appendix Figure 1 - Appendix Figure 3 The rigid component 203 includes a plastic disc 2031, which is fixed between two adjacent sliders 202. The top surface of the plastic disc 2031 has multiple grooves 2032. The soft component 204 includes a nutrient film 2041, which is disposed on the top surface of the plastic disc 2031. The bottom of the nutrient film 2041 has multiple water-permeable holes 2042. The reset component 207 includes a limiting post 2071, one end of which is fixedly connected to one end of the locking block 205. The outer wall of the limiting post 2071 is provided with a reset spring 2072.

[0038] Specifically, the rigid component 203 includes a plastic tray 2031 fixed between two sliders 202, which has good load-bearing capacity and durability, and can stably support the nutrient film 2041 and seedlings. The plastic tray 2031 is fixed between the adjacent sliders 202. The top surface of the plastic tray 2031 has multiple grooves 2032 for positioning and separating seedlings, preventing them from squeezing each other and ensuring the independence of the seedling's growth space. It also facilitates the management of individual seedlings by staff. The bottom of the nutrient film 2041 has multiple permeable holes 2042, allowing the water delivered by the irrigation component 303 to penetrate into the nutrient film 2041 and be absorbed by the seedling roots. At the same time, excess water can flow into the plastic tray 2031 through the permeable holes 2042 and then be discharged through the overflow hole 206 to prevent the nutrient film 2041 from overflowing. 041 is filled with water. The reset assembly 207 includes a limiting post 2071, one end of which is fixedly connected to the locking block 205, and the other end which can slide in the corresponding hole on the inner wall of the bracket 1. It limits the sliding direction of the locking block 205, prevents the locking block 205 from deviating from the track during the sliding process, and ensures the accuracy of the reset action. One end of the limiting post 2071 is fixedly connected to one end of the locking block 205. The outer wall of the limiting post 2071 is provided with a reset spring 2072, which is sleeved on the outer wall of the limiting post 2071. In the natural state, it is in the extended state. When the locking block 205 is pushed, the reset spring 2072 is compressed and stores elastic potential energy. After the external force disappears, the reset spring 2072 releases the elastic potential energy, which drives the limiting post 2071 and the locking block 205 to automatically reset, realizing the automatic locking function of the locking block 205.

[0039] Please see the appendix Figure 3 - Appendix Figure 5 The guiding component 302 includes a conveying pipe 3021, the top of which is connected to the bottom of the water storage tank 301, and a plurality of horizontal pipes 3022 are connected in the middle of the conveying pipe 3021. The irrigation component 303 includes an inclined pipe 3031, one end of which is connected to the outer wall of the horizontal pipe 3022. A plurality of drippers 3032 are provided at the bottom of the inclined pipe 3031. A support leg 4 is provided at the bottom of the support 1. The top surface of the inclined pipe 3031 is fixedly connected to the bottom surface of the inclined plate 304.

[0040] Specifically, the guiding component 302 includes a conveying pipe 3021 whose top is connected to the bottom of the water storage tank 301, serving as the main pipe for water delivery. This conveys water from the water storage tank 301 to the horizontal pipe 3022, ensuring smooth water delivery. The top of the conveying pipe 3021 is connected to the bottom of the water storage tank 301. Multiple horizontal pipes 3022 are connected to the middle of the conveying pipe 3021, perpendicularly connected to it, to distribute the water delivered by the conveying pipe 3021 to each irrigation component 303, achieving lateral water distribution and ensuring that each irrigation component 303 receives sufficient water. The irrigation component 303 includes an inclined pipe 3031... The end of the inclined tube 3031 is connected to the outer wall of the horizontal tube 3022 and is set in an inclined state, which allows water to flow smoothly to the dripper 3032 under the action of gravity. At the same time, the inclined design can avoid water accumulation in the tube and prevent pipe blockage. One end of the inclined tube 3031 is connected to the outer wall of the horizontal tube 3022. Multiple drippers 3032 are set at the bottom of the inclined tube 3031, which slowly drips the water in the inclined tube 3031 to the roots of the seedlings in the form of drip irrigation, avoiding excessive water flow from washing away the seedlings, achieving precise irrigation and improving water utilization. The bottom of the support 1 is provided with a support leg 4 to fix it to the bottom of the support 1, increasing the contact area between the support 1 and the ground and improving the stability of the entire cultivation tray.

[0041] Working principle: The nutrient film 2041 is a soft material filled with nutrients to provide nourishment for the seedlings. The plastic tray 2031 is a rigid material used to support the nutrient film 2041 and the seedlings. The plastic tray 2031 can be easily removed via the slider 202 and the slide rail 201. The thickness of the slider 202 is less than the height of the inner wall of the slide rail 201. When installing the plastic tray 2031, the slider 202 compresses the return spring 2072 through the locking block 205, causing the locking block 205 to retract. After 202 is fully inserted, locking block 205 pops out, and plastic tray 2031 is installed. When removing plastic tray 2031, lift plastic tray 2031 upward so that plastic tray 2031 can pass over locking block 205 and be removed. Overflow hole 206 and nutrient film 2041 are respectively opened at the bottom of plastic tray 2031 and nutrient film 2041, so that excess water can flow down and flow into recycling tank 306 under the guidance of guide groove 305 on the top surface of inclined plate 304, which facilitates seedling cultivation.

[0042] When irrigating seedlings, water is added to the water storage tank 301. Under its own gravity, the water enters the horizontal pipe 3022 through the delivery pipe 3021. The outer wall of the horizontal pipe 3022 is connected to multiple inclined pipes 3031. The inclined pipes 3031 are set at an angle to allow water to flow. Multiple drippers 3032 are set at the bottom of the inclined pipes 3031. Each dripper 3032 corresponds to a groove 2032, which can achieve precise irrigation. Excess water is guided into the recycling tank 306 through the guide trough 305 to realize water recycling and also to recover the nutrient solution rich in the water. Automatic irrigation is achieved through a simple structure, which is low in cost and easy to implement.
