Description

Technical Field

[0001] The utility model belongs to the technical field of the application of aeroponic cultivation, and particularly relates to a root fixing frame for aeroponically cultivated plants. Background Technique

[0002] Aeroponic cultivation is a new cultivation method. It is a soilless cultivation technology that uses a spraying device to atomize nutrient solution into small droplets and directly spray them onto the roots of plants to provide the water and nutrients required for plant growth. Crops are suspended in a closed cultivation device (tank, box or bed), and the roots are exposed inside the cultivation device. The nutrient solution is atomized by the spraying device and then sprayed onto the root surface, reducing the nitrate content of cultivated plants.

[0003] Aeroponic cultivation can double the crop yield. It is a high-tech agriculture that does not use soil or substrate to cultivate plants. Since it replaces the soil environment with an artificially created root environment of crops, it can effectively solve the contradictions in the supply of water, air and nutrients that are difficult to solve in traditional soil cultivation, enabling the crop roots to be in the most suitable environmental conditions, thereby exerting the growth potential of crops and greatly increasing the growth amount and biomass of plants.

[0004] In the prior art, the root fixing frame for aeroponically cultivated plants is to directly open holes in the cultivation device, set a filter net at the bottom of the holes, and then directly place the seeds in the filter net, and then carry out aeroponic cultivation. Although the above structure can also meet the placement needs of plants, the filter net is fixed to the cultivation device. Once the filter net is damaged, it is necessary to disassemble the entire cultivation device to facilitate repair; moreover, a number of holes are provided on the entire cultivation device, which is not convenient for observing the roots of a single hole, and the observation is relatively troublesome.

Detailed implementation manners

[0019] In order to more clearly understand the above objects, features and advantages of the present utility model, the following further describes the present utility model with reference to the drawings and embodiments. It should be noted that, without conflict, the embodiments of the present application and the features in the embodiments may be combined with each other.

[0020] In the following description, many specific details are set forth to fully understand the present utility model. However, the present utility model may also be implemented in other ways different from those described herein. Therefore, the present utility model is not limited by the specific embodiments disclosed in the following specification.

[0021] Embodiment 1, as Figures 1 to 6 shown, the purpose of this embodiment is to provide a plant root fixing frame convenient for application in aeroponic cultivation technology, in order to achieve the purpose of separating and fixing with the cultivation device. For this reason, the aeroponic plant root fixing frame provided in this embodiment includes a fixing frame body 1. The fixing frame body 1 can be regarded as three parts according to its functions. Therefore, the fixing frame body 1 includes a cylindrical part 11, a strip part 12 and a contraction part 13 which are arranged in sequence from top to bottom. Among them, the cylindrical part 11 is arranged in a circular tube shape, and its main purpose is to connect with the support cover 3 so as to be placed on or fixed to the hole of the cultivation device.

[0022] The strip part 12 includes a plurality of connecting strips 121 uniformly connected to the bottom of the cylindrical part 11. In this embodiment, 8 connecting strips 121 are provided, and there are two purposes. One is to realize the connection between the cylindrical part 11 and the contraction part 13, and the other purpose is to facilitate the roots to pass through the gaps between the connecting strips 121. For this reason, the connecting strips 121 provided in this embodiment are arranged at equal intervals at the bottom of the cylindrical part 11.

[0023] The main function of the contraction part 13 is to control the deformation of the entire fixing frame body 1. To this end, the contraction part 13 includes an arc plate 131 arranged at the bottom of the connecting strip 121, that is, an arc plate 131 is arranged under each connecting strip 121, and the arc plates 131 can be arranged in a tubular shape, that is, the corresponding central angle of each arc plate 131 is 45°. In this way, when the arc plates 131 are close to each other, they form a funnel-shaped structure with upper and lower double tubes, and when the arc plates 131 are separated, the entire fixing frame body 1 is arranged like a column as a whole.

[0024] In order to avoid squeezing of seed plants during planting, in the present embodiment, a leakage net 2 is arranged between the strip portions 12. In the present embodiment, the leakage net 2 is arranged in a spherical shape. The purpose of its arrangement in the strip portion 12 is to deform. When the fixing frame body 1 is arranged in a columnar shape, it is spherical, and when the fixing frame body 1 is in a funnel shape, the leakage net 2 will be compressed to be arranged in a pocket shape. This arrangement is convenient for plasticization during planting. For peanuts, it can keep the peanuts in a vertical state without squeezing the peanuts in a funnel shape, thereby facilitating their growth.

[0025] In order to facilitate the placement of the entire fixing frame body 1 in the hole and to facilitate the change of the shape, in this embodiment, the periphery of the cylindrical portion 11 and the contraction portion 13 are provided with external threads, wherein the cylindrical portion 11 is provided with a support cover 3, the support cover 3 includes a nut 31 threadedly connected to the cylindrical portion 11 and a support plate 32 mounted on the top of the nut 31, the diameter of the support plate 32 is larger than the diameter of the hole on the cultivation device, so that the entire fixing frame body 1 is suspended, and the contraction portion 13 can be provided with a connecting nut 4. The setting of the connecting nut 4 enables it to fix the arc plate 131 to form a funnel-shaped structure. Of course, it should be noted that, considering the problem of deformation, the entire fixing frame body 1 is made of plastic material, such as polyethylene, polypropylene, etc. At the same time, in this embodiment, considering the dense plant root system, the leakage hole 21 on the leakage net 2 is a slot hole.

[0026] In order to facilitate the formation of the funnel shape, in this embodiment, a connecting pipe 22 is provided in the middle of the drain 2, a plug hole 221 is provided at the bottom of the connecting pipe 22, and a plug post 132 matching the plug hole 221 is provided on the arc plate 131. In this way, when a funnel shape is required, the plug post 132 is inserted into the plug hole 221 to limit the arc plate 131, thereby facilitating the screwing of the connecting nut 4.

[0027] In order to better cultivate plants, through holes are provided on the sieve 2. The through holes are communicated with the connecting pipe 22. Venting groove holes 222 are provided on the side wall of the connecting pipe 22, and the venting groove holes 222 are evenly distributed on the side wall of the connecting pipe 22. In this way, nutrient solution and moisture will also pass through the through holes to contact the plants. At the same time, the setting of the through holes also forms a certain fixing effect, and part of the seeds or plants will extend into the through holes, so as to maintain the planting and plant states. In addition, the purpose of setting the venting groove holes 222 is to increase the size of the holes to facilitate the extension of the root systems.

[0028] Through the above settings, when the root systems of the plants are just germinating or in the seed stage, the entire fixing frame body 1 is arranged in a funnel shape. When it enters the elongation or meristematic stage, the connecting nut 4 can be unscrewed, and under the action of the self-force of the seed root systems, the plug post 132 is disengaged from the jack 221. Therefore, there is no need for an interference fit between the plug post 132 and the jack 221, and only the column and the hole need to be consistent.

[0029] The above is only a preferred embodiment of the present invention, and it is not a limitation to the present invention in other forms. Any person skilled in the art may use the technical content disclosed above to make changes or modifications into equivalent embodiments with equivalent changes and apply them to other fields. However, as long as it does not depart from the technical solution content of the present invention, any simple modification, equivalent change and modification made to the above embodiments according to the technical essence of the present invention still fall within the protection scope of the technical solution of the present invention.
