Description

Technical Field

[0001] This utility model relates to the field of agricultural planting technology, and in particular to a soilless vegetable cultivation device. Background Technology

[0002] Soilless vegetable cultivation technology has been widely applied in facility agriculture, home gardening, and commercial vegetable planting due to its advantages of water conservation, fertilizer saving, no limitation by soil conditions, short crop growth cycle, and high yield. Current agricultural soilless vegetable cultivation devices typically use a frame as a supporting foundation, on which cultivation tubes are laid out. Nutrient solution is supplied into the cultivation tubes to provide the vegetable roots with the water and nutrients needed for growth, thus achieving soilless cultivation of vegetables.

[0003] However, the cultivation holes in existing cultivation tubes are of fixed diameter. For example, in a soilless cultivation device for vegetable planting with patent application number 202322450687.6, since vegetable roots are naturally spread out, if the cultivation hole is too small, the spread-out roots will have difficulty being inserted smoothly. If the cultivation hole is too large, the roots are prone to excessive tilting after being placed in, losing the positioning constraint of the roots, resulting in uneven contact between the roots and the nutrient solution, which affects the absorption efficiency.

This is only for the convenience of description and does not indicate or imply that the device or element must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation of this utility model.

[0028] Furthermore, it should be noted that, in the description of this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0029] Example 1 like Figures 1 to 7 As shown in the figure, this embodiment proposes a soilless vegetable cultivation device, which includes a frame composed of two sets of support rods 1. Several sets of cultivation tubes 2 arranged in a vertical array are detachably connected to the frame. The cultivation tubes 2 are used to contain the nutrient solution and the root system of the vegetables. A reinforcing rod 14 is detachably connected between the two support rods 1. The reinforcing rod 14 is connected to the support rods 1 on both sides by bolts to enhance the overall stability.

[0030] A main inlet pipe 3 is connected to one side of the support rod 1. The main inlet pipe 3 is detachably connected to one side of the cultivation tube 2. The main inlet pipe 3 can be connected to the corresponding support rod 1 through clamps or the like for initial positioning. A main drain pipe 4 is connected between the two support rods 1. The main drain pipe 4 is connected to the bottom of the cultivation tube 2 and is used to drain the culture medium inside the tube.

[0031] It also includes several sets of cultivation holes 25, which are arranged in a horizontal array on the cultivation tube 2. A positioning sticker 5 is detachably connected to the cultivation hole 25. The positioning sticker 5 has a first end 53 and a second end 54. The first end 53 and the second end 54 can be connected by magnetic attraction or adhesive. When the first end 53 and the second end 54 are connected, the positioning sticker 5 forms an enclosed closed loop structure. The innermost circle of the closed loop structure forms a positioning ring 55 for positioning the vegetable roots.

[0032] In conventional soilless vegetable cultivation designs, vegetable roots are naturally spread out, making it difficult for them to be inserted into the cultivation tube 2 using the cultivation hole 25. If the cultivation hole 25 is enlarged to facilitate root insertion, the root system will lose its positioning constraint, leading to problems such as excessive tilting after insertion, which will affect subsequent growth stability.

[0033] Based on this, this application employs a combination design of cultivation hole 25 and flexible detachable positioning sticker 5 to facilitate the placement and positioning of the root system and prevent excessive tilting. In this application, a relatively large cultivation hole 25 is opened at the top of the cultivation tube 2 to solve the problem of difficulty in root insertion; then, the positioning sticker 5 is used to cover the root system with its inner circle, and the first end 53 and the second end 54 are connected to form a closed loop, realizing the covering and positioning of the root system. By connecting the bottom of the positioning sticker 5 to the top of the cultivation tube 2, the tilting of the root system can be effectively prevented, achieving a balance between convenient placement and stable positioning.

[0034] On the other hand, the limiting sticker 5 is made of flexible material. As the roots gradually thicken with growth, the diameter can be increased by cutting the inner circle of the limiting sticker 5, leaving enough space for the roots to grow, while maintaining the positioning function of the limiting ring 55 on the roots, preventing the roots from becoming excessively crooked due to lack of restraint during the growth process, and ensuring the stable growth of vegetables during the growing season.

[0035] refer to Figure 7 In this embodiment, the limiting sticker 5 includes an outer reference ring 51, which is detachably connected to the top of the cultivation tube 2. Within the inner ring of the reference ring 51, peelable tear-off rings 52 are sequentially connected. Adjacent tear-off rings can be connected by adhesive or other means, forming a tear line at the adhesive joint for easy tearing. The innermost tear-off ring 52 forms the aforementioned limiting ring 55. The design of adjacent tear-off rings 52 connected by tear lines eliminates the need for scissors or other tools; simply peeling along the tear line manually increases the inner ring diameter, allowing for quick adjustment and preventing damage to the root system or the structure of the limiting sticker 5 due to improper cutting.

[0036] Furthermore, the first end 53 and the second end 54 of the positioning sticker 5 are both located at both ends of the reference ring 51, and are connected to each other via magnetic attraction or a reusable adhesive structure. A magnetic connection is used between the bottom surface of the reference ring 51 and the outer wall of the cultivation tube 2. This magnetic connection can reuse the magnetic force below the first end 53 and the second end 54 to connect with the cultivation tube 2, or a reusable adhesive structure can be used. This allows for the detachable connection between the first end 53 and the second end 54, as well as the detachable connection between the positioning sticker 5 and the cultivation tube 2.

[0037] refer to Figure 3 or Figure 5 In this embodiment, the cultivation tube 2 is detachably composed of an upper tube body 21 and a lower tube body 22, with the aforementioned limiting sticker 5 attached to the outer wall of the upper tube body 21. Specifically, an embedding groove 23 is provided above the lower tube body 22, and an embedding block 24 is connected below the upper tube body 21. The embedding groove 23 and the embedding block 24 are fitted and inserted to form the cultivation tube 2. This detachable design allows for the cleaning of aging roots and nutrient solution sediment that may remain on the inner wall of the cultivation tube 2, preventing bacterial growth or blockage of the nutrient solution channels. On the other hand, during crop rotation, the upper tube body 21 can be disassembled separately, allowing for more precise removal of the vegetable roots one by one. Compared to blind operation, this effectively avoids damage to the seedling roots.

[0038] Example 2 Continue to refer to Figures 1 to 7 The rest of the structure is the same as in Embodiment 1. The difference is that in this embodiment, several cultivation tubes 2 are respectively set on the front and back sides of the frame to form two sets of cultivation surfaces. The cultivation tubes 2 in the two sets of cultivation surfaces are arranged in a vertical array. The design of the front and back cultivation surfaces can effectively increase the planting area of ​​vegetables in the frame without taking up too much extra space. Under the same management cost, it can greatly improve the space output efficiency.

[0039] In some embodiments, a support frame 6 is detachably connected between the two support rods 1. A slot 61 is provided within the support frame 6, and at least one set of downward-penetrating perforations 62 are provided within the slot 61. Correspondingly, a plug 7 is fixedly connected to the bottom of the cultivation tube 2. A drain connector 8 is fixedly connected to the bottom of the plug 7, and the drain connector 8 communicates with the inside of the cultivation tube 2. A drain hose 9 is detachably connected to the bottom of the drain connector 8, and the drain hose 9 communicates with the main drain pipe 4, allowing the culture medium in the cultivation tube 2 to be drained into the main drain pipe 4 via the drain connector 8 and the drain hose. On the other hand, a valve body is provided between the drain connector 8 and the drain hose 9, controlling the discharge of liquid from the cultivation tube 2.

[0040] The aforementioned insert 7 is adapted to and connected to the slot 61, and the lower end of the drain connector 8 can freely pass through the slot 61 and the perforation 62 in the support frame 6, extending to the bottom of the support frame 6 and connecting to the drain hose 9. The design of the insert 7 and the slot 61 enables the positioning of the cultivation tube 2, ensuring its stability during cultivation. This detachable design allows for easier replacement of the cultivation tube 2, addressing issues such as damage to a set of cultivation tubes 2 or replacement with cultivation tubes of different diameters during crop rotation, without requiring overall replacement and maintenance, thus reducing equipment maintenance consumable costs.

[0041] Furthermore, to enhance the stability of the cultivation tube 2 after insertion, a through-hole 63 is provided in the slot 61, and a second threaded hole 11 is provided at the bottom of the insertion block 7. When the insertion block 7 is fitted into the slot 61, the central axes of the corresponding first threaded hole 63 and second threaded hole 11 are located on the same axis. A first bolt is also included, which freely passes through the first threaded hole 63 and connects to the second threaded hole 11, thereby more stably fixing the cultivation tube 2 above the support frame 6.

[0042] refer to Figures 1 to 3 In this embodiment, a vertical clearance groove 101 is provided inside the support rod 1, and several sets of positioning holes 102 are provided inside the clearance groove 101. A third threaded hole 103 is provided inside the positioning hole 102. Connecting blocks 10 are respectively connected to both sides of the support frame 6. The connecting blocks 10 have an "L" shape. It also includes a locking member 12, which has a "U" shape and forms a positioning cavity inside for locking the connecting blocks 10. A fourth threaded hole 13 is provided on both sides of the locking member 12. It also includes a second bolt. When the two ends of the locking member 12 are fitted into the positioning holes 102, the fourth threaded hole 13 and the third threaded hole 103 on the locking member 12 are on the same central axis. The second bolt then freely passes through the first threaded hole 63 and is threadedly connected to the third threaded hole 103. With the positioning of the locking member 12, the locking member 12 can fix the support frame 6 between the two support rods 1.

[0043] Different vegetables have significantly different growth characteristics. The adjustable design described above can provide customized growing space for crops. For example, when planting dwarf leafy vegetables, the spacing between the six support frames can be reduced to fully utilize the vertical space of the frame and increase the number of cultivation layers, thereby increasing the planting capacity per unit space. On the other hand, the vertical space requirements of the same crop change continuously from the seedling stage to maturity. This adjustable spacing between the six support frames can adjust the space according to the growth stage, allowing the frame space to dynamically match the growth rhythm.

[0044] In some embodiments, a liquid inlet connector 15 is provided on the side of the cultivation tube 2, and the liquid inlet connector 15 is connected to a liquid inlet hose 16. The other end of the liquid inlet hose 16 is connected to the main liquid inlet pipe 3, and a valve body is provided in the liquid inlet connector 15. The culture medium is delivered to each liquid inlet hose 16 through the main liquid inlet pipe 3, and flows into the cultivation tube 2 through the liquid inlet hose 16 and the liquid inlet connector 15, providing the vegetables in the cultivation tube 2 with the nutrients required for growth. The valve body design can further control whether liquid enters the cultivation tube 2.

[0045] Although the specific embodiments of the utility model have been described above in conjunction with the accompanying drawings, this is not intended to limit the scope of protection of the utility model. Based on the technical solution of the utility model, various modifications or variations that can be made by those skilled in the art without creative effort are still within the scope of protection of the utility model.
