[0029] As shown in Figures 3-8 The expansion assembly 5 comprises threaded rods 51 rotatably connected on both sides of the fixed frame 1. The top of the threaded rod 51 is rotatably connected with a fixed block 52. The top of the fixed block 52 is slidably connected with a moving plate 53. The bottom of the moving plate 53 is provided with a sliding groove 512. The upper surface of the moving plate 53 is provided with a support block 54 on one side. Two support blocks 54 are fixedly connected with arc-shaped planting baskets 55 on the sides close to each other. The bottom of the two arc-shaped planting baskets 55 is provided with a bottom plate 57. The top of the bottom plate 57 is uniformly provided with four limiting grooves 513. The front and rear ends of the top of the bottom plate 57 are also slidably provided with arc-shaped planting baskets 55. The arc-shaped planting baskets 55 are located inside the limiting grooves 513 and slide. The inner surface of the arc-shaped planting basket 55 is provided with a protection assembly 56. The bottom of the bottom plate 57 is provided with a driving component.

[0030] The driving component comprises a circular ring 58 rotatably arranged on the bottom of the bottom plate 57 and a driving rod 510 fixedly arranged on the outer surface of the arc-shaped planting basket 55. The inside of the circular ring 58 is uniformly provided with four driving grooves 59. The inside of the circular ring 58 is threadedly connected with a locking screw 511. One end of the locking screw 511 is in contact with the bottom of the bottom plate 57. The bottom of the driving rod 510 extends into the inside of the driving groove 59. The driving rod 510 and the driving groove 59 are slidably adapted to each other.

[0031] The top of the fixed block 52 is provided with a connecting block which is slidably arranged in the inside of the sliding groove 512 and is adapted. One side of the top of the moving plate 53 is provided with a placing groove. The support block 54 is located in the inside of the placing groove. The threaded rod 51 is connected with the fixed frame 1 through an internal thread plate.

[0032] The four arc-shaped planting baskets 55 are located on the top of the bottom plate 57 and are slidably connected with the bottom plate 57. The four arc-shaped planting baskets 55 are arranged in a ring shape to form a complete flowerpot. The inner bottom of the arc-shaped planting basket 55 is provided with a sponge gasket 6. The four arc-shaped planting baskets 55 are provided with ceramsite which is located above the sponge gasket 6.

[0033] When the plants are grown in water culture, the plants will grow more and more, and the initial planting basket is insufficient to plant a large number of water culture plants, resulting in insufficient planting space inside the planting basket, which can cause the plant to die due to insufficient growth space. At this time, the circular ring 58 can be rotated to drive the four driving grooves 59 to rotate, the driving grooves 59 drive the driving rods 510 to move, the driving rods 510 drive the arc-shaped planting baskets 55 to move inside the limiting grooves 513, so that the four arc-shaped planting baskets 55 are synchronously spread apart outward, so that the space volume between the four arc-shaped planting baskets 55 is increased, which can effectively adapt to plants at different stages and ensure sufficient growth space for the plants. Further rotating the locking screw 511 to lock the circular ring 58, so as to fix the four arc-shaped planting baskets 55 and improve the stability of the device. At different stages, plants need different nutrients, and the volume of the root system of the plant in contact with the nutrient solution needs to be adjusted. The threaded rod 51 is rotated to drive the fixed block 52 and the moving plate 53 to move up and down as a whole under the action of the threads, and the two supporting blocks 54 can synchronously drive multiple arc-shaped planting baskets 55 to move up and down, so as to adjust the contact area of the plant root system with the nutrient solution and ensure that the plant root system can absorb sufficient nutrients.

[0034] And as the arc-shaped planting baskets 55 expand, the moving plate 53 can be pushed to move on the top of the fixed block 52 through the supporting block 54, so that the arc-shaped planting baskets 55 can expand smoothly, and the moving plate 53 can adapt to arc-shaped planting baskets 55 with different expansion degrees. The hay balls fix the plant roots in the appropriate position through physical support, prevent the plants from falling or the roots from floating, and ensure the straight growth of the plants. The sponge gasket 6 can support and stabilize the plant roots, allow air circulation, and prevent the roots from rotting due to lack of oxygen.

[0035] As shown in Figure 9 The protection assembly 56 includes a mounting frame 561 fixed to one side of the inner surface of the arc-shaped planting basket 55, a rotating roller 564 rotatably connected inside the mounting frame 561, a coil spring 562 fixedly connected to the top and bottom of the outer surface of the rotating roller 564, and a non-woven fabric 563 sleeved on the outer surface of the rotating roller 564.

[0036] One side of the non-woven fabric 563 extends out of the inside of the mounting frame 561, and one side of the non-woven fabric 563 is fixedly connected to the side edge of the adjacent arc-shaped planting basket 55.

[0037] The coil spring 562 is fixedly connected to the top inside the mounting frame 561, the other end of the non-woven fabric 563 is fixedly connected to the outer surface of the rotating roller 564, and the non-woven fabric 563 is wound on the outer surface of the rotating roller 564.

[0038] When the plurality of arc-shaped planting baskets 55 are expanded, gaps exist between the arc-shaped planting baskets 55 and the arc-shaped planting baskets 55, and the gaps can cause the ceramsite to fall off, so that the plant root system lacks effective physical support, which can cause the plant to lodge or the root system to float. Therefore, when the four arc-shaped planting baskets 55 are expanded away from each other, the non-woven fabric 563 is pulled out from the inside of the mounting frame 561 due to the fact that one end of the non-woven fabric 563 is fixed to another arc-shaped planting basket 55, the rotating roller 564 is driven to rotate and the coil spring 562 is twisted, so that the non-woven fabric 563 shields the gap between the two arc-shaped planting baskets 55, which can effectively prevent the ceramsite from falling off from the gap between the two arc-shaped planting baskets 55. At the same time, when the arc-shaped planting baskets 55 are close to each other, the rotating roller 564 is driven to rotate and the non-woven fabric 563 is wound up under the action of the restoring force of the coil spring 562.

[0039] Method for use: The four arc-shaped planting baskets 55 are used to plant plants such as peppermint and rosemary inside, which can release volatile substances such as menthol to achieve the effects of mosquito repellent and refreshing. By starting the nutrient solution pump machine 26, the nutrient solution in the nutrient solution storage tank 24 can be transported to the inside of the ultrafiltration membrane 4 through the nutrient solution pipe 28. By starting the water-soluble formaldehyde adsorbent pump machine 25, the formaldehyde adsorbent in the water-soluble formaldehyde adsorbent storage tank 23 can be transported to the space between the culture pond 3 and the ultrafiltration membrane 4 through the adsorbent pipe 27. The ultrafiltration membrane 4 can separate the nutrient solution and the formaldehyde adsorbent. When the nutrient solution and the formaldehyde adsorbent are insufficient, the solution can be supplemented in time through the nutrient solution pump machine 26 and the water-soluble formaldehyde adsorbent pump machine 25, which solves the problem of manual addition of nutrient solution and water-soluble formaldehyde adsorbent due to insufficient supply and the problem of lack of formaldehyde removal capacity of the nutrient solution; The ceramsite fixes the plant root system in a suitable position by physical support to prevent the plant from lodging or the root system from floating, and ensures the straight growth of the plant. The sponge gasket 6 can support and stabilize the plant root system, allow air to circulate, and prevent the root system from rotting due to lack of oxygen; The rotating ring 58 drives the four driving grooves 59 to rotate, the driving grooves 59 drive the driving rods 510 to move, the driving rods 510 drive the arc-shaped planting baskets 55 to move in the limiting grooves 513, so that the four arc-shaped planting baskets 55 are synchronously moved away from the shaft to expand, the volume of the space between the four arc-shaped planting baskets 55 is increased, which can effectively adapt to plants at different stages and ensure sufficient growth space for the plants. Further rotation of the locking screw 511 locks the rotating ring 58, so that the four arc-shaped planting baskets 55 can be fixed, and the stability of the device is improved. When the four arc-shaped planting baskets 55 are mutually distanced and expanded, due to the fact that one end of the non-woven fabric 563 is fixed with the other arc-shaped planting basket 55, the non-woven fabric 563 is pulled out from the inside of the mounting frame 561, drives the rotating roller 564 to rotate and twists the coil spring 562, so that the non-woven fabric 563 shields the gap between the two arc-shaped planting baskets 55, which can effectively prevent the haydite from falling off from the gap between the two arc-shaped planting baskets 55, and at the same time, when the arc-shaped planting baskets 55 are mutually approached, the coil spring 562 drives the rotating roller 564 to rotate and wind the non-woven fabric 563 under the action of the restoring force.

[0040] The above merely describes the preferred embodiments of the present application; however, the protection scope of the present application is not limited to this. Any person skilled in the art can make equivalent replacements or changes to the technical solutions and the improved concepts of the present application within the technical range disclosed by the present application, which should be covered by the protection scope of the present application.
