Description

Technical Field

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

[0002] Soilless cultivation refers to a cultivation method that uses water, peat moss, forest humus, vermiculite, or other media as a substrate to fix the plant's roots, allowing the plant roots to directly contact the nutrient solution. In soilless cultivation, the composition of the nutrient solution is easy to control and can be adjusted at any time. It can be carried out in places with suitable light and temperature but no soil, such as deserts, beaches, and desert islands, as long as there is a certain amount of fresh water available.

[0023] See Figures 1-3This utility model provides a hydroponics device, including a hollow mounting cylinder 1. Both ends of the mounting cylinder 1 are provided with end caps 11, and the side of the end caps 11 away from the mounting cylinder 1 is connected to a connecting cylinder 12. The interior of the connecting cylinder 12 is connected to the interior of the mounting cylinder 1. Cultivators can pour nutrient solution for hydroponics into the mounting cylinder 1 through the connecting cylinder 12. (If the hydroponics area is large, several mounting cylinders 1 can be connected together through the connecting cylinders 12. If the hydroponics area is small, the connecting cylinder 12 needs to be set with a certain arc. By adjusting the arc of the mounting cylinder 1, the liquid level of the nutrient solution in the mounting cylinder 1 can be controlled to ensure normal plant growth.) Several cultivation cylinders 2 are inserted through the mounting cylinder 1. The end of each cultivation cylinder 2 near the mounting cylinder 1 is inserted into the mounting cylinder 1. Each end of the cultivation cylinder 2 inserted into the mounting cylinder 1 has several hollow grooves 22. At the time, the cultivation cylinder 2 is filled with a certain amount of substrate (large-particle inorganic substrate or organic substrate suitable for soilless cultivation). The diameter of the perforated groove 22 is smaller than the diameter of the substrate to prevent the substrate from falling out and to facilitate the roots of the plant to penetrate into the installation cylinder 1. The cultivation cylinder 2 is symmetrically provided with extension plates 21, and each extension plate 21 is slidably provided with a positioning rod 24 (each positioning rod 24 is symmetrically provided with a sliding groove 241, and each extension plate 21 is symmetrically provided with a slider, which is slidably set in the sliding groove 241). The friction between the positioning rod 24 and the extension plate 21 is relatively large. Under the premise of no external interference, the relative position between the extension plate 21 and the positioning rod 24 will not change. The installation cylinder 1 is provided with a certain number of fixing seats 13 that cooperate with the positioning rod 24 (the positioning rod 24 and the fixing seat 13 correspond one-to-one). The end of the positioning rod 24 near the fixing seat 13 is inserted into the fixing seat 13.

[0024] See Figures 1-3 Furthermore, each extension plate 21 is elastically connected with a locking block 211 for locking the position of the positioning rod 24 (the end of the locking block 211 near the extension plate 21 is inserted into the extension plate 21 to abut against the positioning rod 24, the locking blocks 211 inside the extension plate 21 are symmetrically provided with inserts, the extension plate 21 is provided with slots that cooperate with the inserts, the inserts are slidably disposed in the slots, and elastic elements 3 are provided between the inserts and the slots). The locking block 211 can further improve the stability of the cultivation cylinder 2 and prevent the relative position of the extension plate 21 and the positioning rod 24 from changing when the plant grows. By pulling the locking block 211 away from the positioning rod 24, the locking block 211 disengages from the positioning rod 24, and the relative position between the cultivation cylinder 2 and the positioning rod 24 can be adjusted.

[0025] See Figures 1-3 Preferably, the elastic element 3 is a spring, which provides the return force.

[0026] See Figures 1-3Preferably, the locking block 211 is provided with anti-slip surfaces at one end near the positioning rod 24 and on the outside of the positioning rod 24, which further increases the friction between the locking block 211 and the positioning rod 24.

[0027] See Figures 1-3 Preferably, the number of hollow grooves 22 is set to one, and a blocking ring 23 is provided inside the hollow groove 22. There is a gap between the blocking ring 23 and the cultivation cylinder 2. The blocking ring 23 is provided with a through hole. Several connecting plates are provided between the blocking ring 23 and the cultivation cylinder 2, which can facilitate the roots of plants to pass through and block the substrate to prevent the substrate from falling off.

[0028] See Figures 1-3 When in use, the grower places the substrate and plants inside the cultivation tube 2, and according to the space required by the plant roots, before installing the cultivation tube 2 onto the installation tube 1, pulls the locking block 211 to adjust the relative position between the cultivation tube 2 and the positioning rod 24, thereby adjusting the height of the cultivation tube 2 extending out of the installation tube 1 after installation. After adjustment, the locking block 211 is released so that the positioning rod 24 is aligned with the fixing seat 13, and the bottom end of the cultivation tube 2 is inserted into the installation tube 1 so that the bottom end of the cultivation tube 2 is just below the nutrient solution level inside the installation tube 1. During the plant growth process, the cultivation tube 2 can be pulled out to observe the growth of the plant roots, and the height of the cultivation tube 2 extending out of the installation tube 1 can be adjusted at any time according to the water requirements of the plant roots by adjusting the relative position between the cultivation tube 2 and the positioning rod 24.

[0029] This utility model provides a soilless cultivation device, including an installation cylinder and a cultivation cylinder, which work together to allow for real-time observation of plant root growth without affecting plant growth. The height of the cultivation cylinder extending beyond the installation cylinder can be adjusted according to the water requirements of the plant roots by regulating the relative position between the cultivation cylinder and the positioning rod. Each extension plate is elastically connected to a locking block for locking the position of the positioning rod, further enhancing the stability of the cultivation cylinder and preventing changes in the relative position of the extension plate and the positioning rod during plant growth. The installation cylinder and cultivation cylinder components are simple in structure, low in production cost, and easy to install. In summary, the advantages of this utility model are: it allows for real-time observation of plant root growth without affecting plant growth, and it has a simple structure, low production cost, and is easy to install.
