Description

Technical Field

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

[0002] Hydroponics, as an important form of soilless cultivation, directly immerses plant roots in a nutrient solution, replacing soil to provide the water, nutrients, and dissolved oxygen needed for plant growth. It boasts significant advantages such as resource conservation, environmental friendliness, and high production efficiency, leading to its increasingly widespread application. In practice, to improve facility space utilization and reduce unit production costs, a common practice for tobacco cultivation is to use large-area hydroponic tanks combined with floating planting boards. However, these methods have significant technical bottlenecks: Firstly, the planting board's prolonged contact with the liquid surface restricts effective exchange between the nutrient solution and air, easily leading to persistently low dissolved oxygen levels, causing root hypoxia, hindering tobacco plant growth, and even causing root rot and other physiological disorders. Secondly, to maintain the physicochemical balance of the nutrient solution and prevent the accumulation of harmful substances, it must be thoroughly replaced regularly. Current replacement procedures typically rely on manual handling of each individual hydroponic unit, making the nutrient solution replacement process cumbersome, time-consuming, and difficult to manage simultaneously. This decentralized and inefficient method of changing the hydroponic solution not only significantly increases the labor costs and intensity of production management, but also becomes a pain point that restricts the development of hydroponic systems towards large-scale, automated, and standardized development.

[0003] Therefore, the inventor of the utility model proposes a seedling raising device and a hydroponic device to solve the above-mentioned technical problems. Utility Model Content

[0022] This embodiment proposes a seedling raising device, such as... Figures 1 to 7 As shown, it includes a seedling unit 211 and a seed base 5. The seedling unit 211 includes a seedling box 2111 and a base matching sieve plate 2112 erected on the seedling box 2111. A culture chamber 2113 is formed inside the seedling box 2111.

[0026] In this embodiment, multiple mounting racks 11 are integrated through the hydroponic rack 1, and each mounting rack 11 is equipped with a hydroponic component 2 to achieve three-dimensional cultivation, saving planting space. After the liquid inlet unit 3 is started, the nutrient solution is continuously injected into the culture chamber 2113 of each seedling unit 211 through the water inlet interface 2115. The closed cavity formed by the seedling box 2111 and the matching screen plate 2112 of the base provides a stable growth environment for the plant roots. The planting hole 2114 is used to accommodate the tobacco plant and immerse the roots in the nutrient solution. There is a gap of 5mm to 15mm between the highest liquid level of the nutrient solution in the culture chamber 2113 and the matching screen plate 2112 of the base. The gap forms an air buffer layer, which is conducive to the aerobic respiration of the tobacco plant roots.

[0027] In a preferred embodiment, the liquid inlet unit 3 includes a water pump, a main liquid inlet pipe 31, and at least one liquid inlet distribution pipe 32. Each liquid inlet distribution pipe 32 is connected to a branch liquid inlet pipe 33, and a water inlet valve 34 is provided on the branch liquid inlet pipe 33. Each branch liquid inlet pipe 33 is connected to the main liquid inlet pipe 31, and the water pump is connected to the main liquid inlet pipe 31.

The inlet valves 34 on the branch inlet pipes 33 can independently adjust the flow rate of each area to achieve nutrient supply control. The main inlet pipe 31 is connected to multiple inlet distribution pipes 32. Each inlet distribution pipe 32 is connected to an inlet distribution pipe through multiple distribution interfaces 35, forming a multi-channel distribution network. The nutrient solution is delivered to the inlet interface 2115 of each seedling unit 211 via the inlet distribution pipe and is evenly injected into the culture chamber 2113. The inlet unit 3 and the hydroponic component 2 on the hydroponic rack 1 are seamlessly connected through the piping system, forming a closed-loop circulation with the outlet unit 4 to achieve centralized supply of nutrient solution.

The bottom of the main liquid outlet pipe 41 is connected to a water outlet valve.

[0030] In this embodiment, the liquid outlet unit 4 is connected to multiple liquid outlet distribution pipes 42 through the main liquid outlet pipe 41 to form a collection network. Each liquid outlet distribution pipe 42 is provided with multiple liquid outlet interfaces 43, which are connected to the water outlet interfaces 2116 of each seedling unit 211 through the liquid outlet diversion pipe. When changing the nutrient solution, the water outlet valve is opened, and the nutrient solution in the culture chamber 2113 flows out from the water outlet interface 2116, flows into the liquid outlet distribution pipe 42 through the liquid outlet diversion pipe, and is finally discharged through the main liquid outlet pipe 41.

[0031] In one embodiment, a seed base 5 is installed inside the planting hole 2114. The bottom of the seed base 5 has several strip grooves 51. When the seed base 5 is installed inside the planting hole 2114, the strip grooves 51 communicate with the culture chamber 2113 below, forming a nutrient solution flow channel. In the early stages of sowing, the seeds are stably placed inside the seed base 5, and the strip grooves 51 allow the nutrient solution to permeate around the seeds, promoting seed germination and primary root penetration. As the root system grows, the strip grooves 51 continuously guide the roots to naturally extend into the nutrient solution within the culture chamber 2113, ensuring the roots absorb water and nutrients while also increasing the contact area between the nutrient solution and the roots through the strip grooves 51, thus improving dissolved oxygen transfer efficiency.

[0032] In another embodiment, a root tube 6 is installed inside the planting hole 2114. The root tube 6 includes a tube body 61 and a cap 62 threadedly connected to the tube body 61.

The central hole 63 of the cap 62 is adapted to the diameter of the tobacco plant stem. During installation, the tobacco plant stem passes through the central hole 63 of the cap 62, and the roots naturally descend into the nutrient solution in the culture chamber 2113 along the inner wall of the tube body 61. The side wall of the tube body 61 may also have hidden ventilation holes or be made of microporous material to ensure that the nutrient solution wets the roots while promoting air infiltration and maintaining dissolved oxygen balance.

[0033] As a preferred embodiment, the bottom of the hydroponic rack 1 is provided with multiple casters to facilitate the transportation of the hydroponic rack 1.

[0034] In a preferred embodiment, the bottom of the hydroponic rack 1 is equipped with a nutrient solution tank and a waste liquid tank. The main inlet pipe 31 extends into the nutrient solution tank, and the main outlet pipe 41 extends into the waste liquid tank. The prepared nutrient solution is pumped to the inlet unit 3 by a water pump and evenly distributed to the water inlet interface 2115 of each seedling unit 211 through branch pipes. The main outlet pipe 41 is connected to the top of the waste liquid tank to receive the waste liquid discharged from the water outlet interface 2116 of each seedling unit 211, realizing centralized recycling of waste liquid. This achieves full-process management of nutrient solution supply, use and discharge, reduces manual operation intensity, and features a compact structure and strong practicality.
