Description
Technical Field
[0001] This utility model relates to the field of hydroponic vegetable technology, and more specifically, to an automatic nutrient solution circulation structure for hydroponic vegetables. Background Technology
[0002] Hydroponic vegetables refer to vegetables cultivated in a way that differs from traditional soil cultivation, where most of their roots grow in a nutrient solution layer, and the nutrient solution provides them with water, nutrients, and oxygen. Hydroponic vegetables have a short growth cycle and are rich in various vitamins and minerals essential to the human body. Hydroponics is a type of soilless cultivation, classified as substrate-free cultivation. Substrate-free cultivation means that the plant roots grow in an environment without a substrate to anchor them; the roots grow in a nutrient solution or moist air containing nutrient solution, although some substrate may be used during seedling cultivation.
[0003] Traditional nutrient solution circulation systems for hydroponically grown vegetables typically involve placing seedlings in the planting basket of the device, with a water pump delivering the nutrient solution to the uppermost hydroponic container. These containers are interconnected, allowing the nutrient solution to circulate within the device, providing nutrition to the hydroponic vegetables while achieving automatic circulation. However, existing systems cannot adjust the fixed height of the hydroponic containers to suit planting needs. This can easily lead to vegetables not being in optimal light positions, resulting in insufficient or excessive light, which negatively impacts their normal growth. Furthermore, the fixed height of the hydroponic containers cannot provide suitable growing space as vegetables change at different growth stages, restricting their growth. In later stages of growth, insufficient space may cause plants to crowd each other, affecting their normal shape and development, and reducing the commercial value of the vegetables.
[0004] Therefore, we have made improvements and proposed an automatic nutrient solution circulation structure for hydroponic vegetables. Utility Model Content
[0005] The purpose of this invention is to address the issue that traditional automatic nutrient solution circulation structures for hydroponic vegetables typically involve placing seedlings in the planting basket of the device and using a water pump to deliver the nutrient solution to the uppermost hydroponic container.

However, these devices cannot adjust the fixed height of the hydroponic containers according to planting needs, which can easily lead to vegetables not being in optimal light positions. This can result in insufficient or excessive light, affecting the normal growth of the vegetables. Furthermore, the fixed height of the hydroponic containers cannot provide suitable growing space for the vegetables as their height and shape change at different growth stages, thus restricting their growth. In the later stages of growth, the plants may crowd each other due to insufficient space, affecting their normal shape and development, and reducing the commercial value of the vegetables.

The height adjustment assembly 6 includes multiple mounting teeth 601, the bottoms of which are fixedly connected to the four corners of the top of the base 1. A first movable block 602 is movably connected to the surface of the mounting teeth 601. A connecting plate 603 is fixedly connected to the inner side of the first movable block 602. A first sliding rod 604 is fixedly installed in the inner cavity of the connecting plate 603. A second movable block 605 is movably connected to the surface of the first sliding rod 604. A second sliding rod 606 is fixedly installed at both the upper and lower ends of the inner side of the second movable block 605. The front end of the second sliding rod 606 passes through the front side of the connecting plate 603 and is fixed. A connecting block 607 is connected to the first movable block 602. Mounting brackets 608 are fixedly connected to the inner sides of both the second movable block 605 and the connecting block 607. A gear post 609 is movably connected to the inner cavity of the first movable block 602. The gear post 609 meshes with the surface of the mounting gear post 601. The front end of the gear post 609 extends through to one side of the first movable block 602 and is fixedly connected to a ratchet 610. A movable pawl 611 is movably connected to the left side of the ratchet 610. The rear side of the movable pawl 611 is movably connected to the front side of the first movable block 602. A damper 612 is provided at the top of the movable pawl 611. A limit block 613 is movably connected to the top of the damper 612. The limit block 613 is connected to the first movable block 602. The front side of the 02 is fixedly connected. The front side of the ratchet 610 is provided with a mounting plate 614. The front end of the ratchet 610 passes through to one side of the mounting plate 614 and is fixedly connected to a rocker wheel 615. The rear end of the gear column 609 passes through to one side of the first movable block 602 and is fixedly connected to a first connecting rod 616. The rear end of the first connecting rod 616 is fixedly installed with a first bevel gear 617. One side of the first bevel gear 617 is meshed with a second bevel gear 618. The right side of the second bevel gear 618 is fixedly connected to a second connecting rod 619. Two mounting blocks 620 are movably connected to the surface of the second connecting rod 619. The two first movable blocks 602 are fixedly installed on the rear side of the connecting plate 603.
[0040] In implementation, when using the device, firstly, the rocker wheel 615 is rotated clockwise as needed, causing the ratchet 610 to rotate in the same direction. Through the cooperation of the ratchet 610, the movable pawl 611, the damper 612, and the limit block 613, the ratchet 610 is prevented from reversing during height adjustment. Simultaneously, the ratchet 610 drives the gear post 609 on the left side of the device to rotate. Furthermore, the first connecting rod 616 on the left side connects the two gear posts 609 on the left side, causing them to rotate simultaneously, which in turn drives the first bevel gear 617 to rotate. When the first bevel gear 617 and the second bevel gear 618 on the left side of the device mesh, the second bevel gear 618 on the left side rotates, which in turn drives the second connecting rod 619 to rotate inside the mounting block 620, thereby driving the first bevel gear 617 on the right side to rotate. Simultaneously, through the meshing of the first bevel gear 617 and the second bevel gear 618 on the right side of the device, the gear post 609 on the right side of the device rotates. Through the meshing between the gear post 609 and the teeth on the surface of the mounting gear post 601, the gear post 609 rotates towards the surface of the mounting gear post 601. The mounting bracket 608 is moved upwards to adjust its fixed height. When the fixed height of the mounting bracket 608 needs to be lowered, the movable pawl 611 is first pressed downwards, causing one end of the movable pawl 611 to rise and simultaneously compress the damper 612, thereby disengaging the movable pawl 611 from the ratchet 610. Then, the rocker wheel 615 is rotated counterclockwise to move the gear post 609 downwards on the surface of the mounting gear post 601, thereby adjusting the fixed height of the mounting bracket 608. Finally, the mounting bracket 608 is pulled, and the fixed height is adjusted via the connecting plate 603 and the first sliding... The cooperation between rod 604, second movable block 605, second sliding rod 606 and connecting block 607 allows the mounting frame 608 to be removed from the device, facilitating the transplanting and harvesting of vegetables. Then, the seedlings are transplanted into the planting trough 10 to achieve the transplanting of seedlings. Then, the nutrient solution is drawn from the water storage tank 4 by the water pump 5, and then transported to the top planting tray 8 through the corrugated pipe 11. Then, through the cooperation between the corrugated pipe 11 and the planting tray 8, the nutrient solution flows from top to bottom into the bottom planting tray 8, and then flows into the water storage tank 4 after being filtered by the filter assembly 3.
[0041] Example 2
[0042] The filter assembly 3 includes a filter box 301, which is fixedly installed on the top left side of the base 1. A movable hinge 302 is provided on the top right side of the filter box 301. A movable door 303 is fixedly connected to the left side of the movable hinge 302. A movable latch 304 is provided on the top left side of the movable door 303. A locking hole that cooperates with the movable latch 304 is provided on the top of the filter box 301. Two mounting slots are provided in the inner cavity of the filter box 301, and filter screens 305 are slidably connected in both mounting slots.
[0043] In the implementation process, when the device is in use, the nutrient solution flows from the inside of the planting tray 8 into the filter box 301 through the connection between the water storage tank 4 and the planting tray 8. Then, it is filtered through the filter screen 305. After filtration, the nutrient solution flows from the filter box 301 into the water storage tank 4. When it is necessary to remove and clean the filter screen 305 inside the filter box 301, first, the movable lock 304 is rotated to release the fixation between the movable box door 303 and the filter box 301. Then, the movable box door 303 is opened by folding it up. Then, the filter screen 305 is pulled out from the filter box 301 by pulling it upward, which facilitates the replacement and cleaning of the filter screen 305.
