[0036] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0037] Please see Figures 1-13 As shown, the purpose of this embodiment is to provide a support frame for hydroponics of watermelons, including a fixed base 1. A connecting plate 11 is rotatably arranged inside the fixed base 1. Two height-adjustable support rods 2 are symmetrically arranged on the connecting plate 11. Each support rod 2 includes an outer cylinder 21 and an inner rod 22. The inner rod 22 is slidably engaged inside the outer cylinder 21. Several cultivation boxes 3 for cultivating watermelon seedlings are arranged between the two support rods 2. A drip irrigation component 5 for drip irrigation of nutrient solution for watermelon seedlings is also provided on the connecting plate 11. A liquid receiving plate 4 for receiving excess nutrient solution is provided at the bottom of each cultivation box 3. Support rods for supporting and fixing the support rods 2 are symmetrically arranged on the connecting plate 11.

[0038] A slot 211 is provided at the center of the outer cylinder 21. Two grooves 212 communicating with the slot 211 are symmetrically provided inside the outer cylinder 21. Several limiting grooves 213 are also provided inside the outer cylinder 21, and the limiting grooves 213 are all communicating with the slot 211 and the grooves 212.

[0039] A number of limiting blocks 221 are symmetrically fixedly connected to the outer wall of the inner rod 22. The inner rod 22 is inserted into the slot 211, and the limiting blocks 221 are inserted into the groove 212. The thickness of the limiting blocks 221 is less than the thickness of the limiting groove 213. When it is necessary to fix the length of the extended end of the inner rod 22, the inner rod 22 is rotated so that the limiting blocks 221 are engaged in the limiting groove 213.

[0040] Both the outer cylinder 21 and the inner rod 22 have several limiting holes 222 on their side walls. A spring 223 is fixedly connected inside the limiting hole 222. One end of the spring 223 is fixedly connected to the inner wall of the limiting hole 222, and the other end of the spring 223 is fixedly connected to a limiting plate 224. The limiting plate 224 is used to protect the spring 223 and prevent it from shifting and being damaged under the action of external force. It can also provide a larger contact area. A fixing block 24 is provided below the limiting hole 222.

[0041] Both sides of the cultivation box 3 are fixedly connected to mounting shafts 31, which are inserted into limiting holes 222. When installing the cultivation box 3, the mounting shaft 31 on the left side is inserted into the limiting hole 222 of the left support rod 2, and moves inward to push the limiting plate 224 to slide, thereby compressing the spring 223. As the mounting shaft 31 goes deeper, the compression of the spring 223 will gradually increase until it reaches its maximum contraction limit, and at this time the mounting shaft 31 on the right side is exactly aligned with the limiting hole 222 on the right side. The insertion ends are aligned parallel, and then the cultivation box 3 is moved to the right. The right mounting shaft 31 is gradually inserted into the right limiting hole 222, and the right limiting plate 224 is also pushed inward to compress the right spring 223. When the mounting shafts 31 on both sides are fully inserted into the limiting hole 222, the springs 223 on both sides will gradually return to their original state, providing uniform support for the cultivation box 3. At this time, the cultivation box 3 is firmly installed on the support rod 2, and the watermelon cultivation work can begin.

[0042] During the seedling stage of watermelon, the plants are small and require a small spacing to save space and facilitate management. As the plants grow, especially after fruit formation, a larger spacing is needed to provide sufficient growth space. Therefore, it is necessary to adjust the length of the protruding end of the inner rod 22 inside the outer cylinder 21 to expose the limiting hole 222 on the side wall of the inner rod 22 for installing the cultivation box 3. In specific adjustment, the inner rod 22 is slid along the slot 211, and the limiting block 221 is placed in the groove 212. The outer wall of the inner rod 22 is marked with a line to indicate that the limiting block 221 is aligned with the limiting groove 213. When the limiting block 221 of the appropriate height is aligned with the limiting groove 213, the inner rod 22 is rotated counterclockwise to engage the limiting block 221 in the limiting groove 213, thereby fixing the overall height of the support rod 2. To further ensure the stability of the inner rod 22, a magnetic block is embedded in the limiting block 221. At the same time, a magnetic block is also embedded in the side wall of the outer cylinder 21 near the limiting groove 213. When the limiting block 221 is engaged in the limiting groove 213, the two magnetic blocks will attract each other, thereby further fixing the height of the inner rod 22. This adjustable spacing can adapt to different varieties of watermelons, such as small or large watermelons, improving the versatility of the support. Users can flexibly adjust the height of the support according to the growth needs and variety characteristics of the watermelon to ensure that the watermelon plant gets enough growth space.

[0043] Furthermore, several through holes 32 are provided through the cultivation box 3, and peat moss, vermiculite and perlite are evenly laid inside the cultivation box 3 to provide good air permeability and water retention, while meeting the nutrients required for watermelon growth. The cultivation box 3 has slots 33 at both ends of the top.

[0044] The top two ends of the liquid receiving plate 4 are symmetrically fixed with inserts 41. The inserts 41 are inverted L-shaped. One end of the insert 41 is inserted into the slot 33. The connection between the insert 41 and the liquid receiving plate 4 is made of silicone material, which has a certain degree of elasticity. When installing the liquid receiving plate 4, the liquid receiving plate 4 is placed below the cultivation box 3. Then, the inserts 41 are twisted and pried open to both sides of the liquid receiving plate 4. When the inserts 41 are above the slot 33, the pulling force on the inserts 41 is stopped. The inserts 41 are then slid into the slot 33 and locked in place, thereby fixing the position of the liquid receiving plate 4. The upper surface of the liquid receiving plate 4 is inclined and concave from both sides to the middle to prevent liquid from dripping from both sides onto the watermelon seedlings below.

[0045] A U-shaped support plate 34 is fixedly connected to the side wall of the cultivation box 3. A connecting rod 35 perpendicular to the support plate 34 is snapped onto the support plate 34. A protrusion is fixedly connected to the center of the bottom of the connecting rod 35. The protrusion is snapped onto the support plate 34, thereby providing further stable support for the connecting rod 35. A net bag 36 for supporting the shaped watermelon is fixedly connected to the bottom of the connecting rod 35. The net bag 36 is made of elastic material to avoid damaging the shaped watermelon.

[0046] The drip irrigation component 5 includes a distribution pipe 51, with a conduit 52 fixedly connected to the center of the distribution pipe 51. Several branch pipes 53 perpendicular to the distribution pipe 51 are connected to the distribution pipe 51, each branch pipe 53 being located on the upper side of the cultivation box 3. Several inclined drip irrigation heads 54 are connected to the branch pipes 53, and a nutrient solution box 16 is fixedly installed on the connecting plate 11. The conduit 52 is connected to the nutrient solution box 16, and the nutrient solution is pumped from the nutrient solution box 16 to the distribution pipe 51 through the conduit 52, then evenly distributed to the branch pipes 53, and finally dripped onto the watermelon seedlings through the drip irrigation heads 54 on the branch pipes 53. The roots of watermelons are usually concentrated in the lower layer of soil or cultivation medium. The inclined arrangement of the drip irrigation heads 54 allows water droplets to fall directly onto the concentrated area of ​​the roots, thereby improving water utilization efficiency.

[0047] Connecting shafts 13 are fixedly connected to both sides of the connecting plate 11. The connecting shafts 13 pass through and are rotatably mounted on the side wall of the fixed base 1. A power source 12 is fixedly mounted on the outer wall of the fixed base 1. The power source 12 is preferably a micro motor. The motor output shaft is fixedly connected to the center of the connecting shaft 13. The motor drives the connecting shaft 13 to rotate, thereby driving the connecting plate 11 to rotate, and then driving the bracket on it to rotate, so as to provide good light conditions for the watermelon seedlings according to the light.

[0048] To support and fix the support rod 2 and prevent it from tipping over, the outer wall of the outer cylinder 21 is symmetrically provided with a first support rod 14. The first support rod 14 is fixedly connected to the upper surface of the connecting plate 11. The connecting plate 11 is also fixedly connected with a second support rod 15. One end of the second support rod 15 is fixedly connected to an arc-shaped support plate, and the support plate is in close contact with the outer wall of the inner rod 22.

[0049] In practical use, this invention adjusts the length of the inner rod 22 extending into the outer cylinder 21 according to the growth stage and variety characteristics of the watermelon seedlings. Observing the marking lines on the outer wall of the inner rod 22, when the appropriate height limit block 221 aligns with the limit groove 213, the inner rod 22 is rotated counterclockwise to engage the limit block 221 within the limit groove 213, thus fixing the height. The mounting shafts 31 on both sides of the cultivation box 3 are inserted into the limit holes 222 of the left and right support rods 2, respectively, and a stable installation is achieved through the compression spring 223. The liquid receiving plate 4 is placed below the cultivation box 3, and the insert block 41 is twisted and pried open towards both sides of the liquid receiving plate 4, and then inserted into the cultivation box. The seedlings are fixed in the slot 33 at the top of the cultivation box 3. Peat moss, vermiculite and perlite are evenly spread on the cultivation box 3 and the watermelon seedlings are placed on it. An appropriate amount of nutrient solution is added to the nutrient solution box 16 and the drip irrigation system is started. The nutrient solution is pumped from the nutrient solution box 16 to the distribution pipe 51 through the conduit 52, and then evenly distributed to the branch pipe 53. Finally, it is dripped onto the watermelon seedlings through the drip irrigation head 54. Excess nutrient solution drips from the through hole 32 onto the liquid receiving plate 4 and is collected. According to the light conditions, the connecting plate 11 is driven to rotate by the power source 12, thereby driving the support and the cultivation box 3 to rotate, ensuring that the watermelon seedlings receive good light conditions and promoting healthy growth.

[0050] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to preferred embodiments, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model.
