An oxygen supply component for supplying oxygen to the plants in the planting dishes 106 is provided on one side of each connecting plate 104 on both sides.

[0024] It should be noted that by setting up the storage tank 2 and the infusion pipes 3 on both sides, the nutrient solution is supplied to the plants while simultaneously circulating, thus maintaining the fluidity of the nutrient solution at all times. This achieves the economical use of the nutrient solution and reduces the risk of its deterioration.

[0025] Please see Figures 3-5The oxygen supply assembly in the drawing includes a first connecting pipe 401 arranged on the connecting plate 104, one side of the first connecting pipe 401 is fixedly connected with a second connecting pipe 402, one end of the second connecting pipe 402 is connected with the supporting rod 103, one end of the first connecting pipe 401 close to the planting box 105 is connected with a third connecting pipe 403 through a universal joint, the bottom of the planting box 105 is provided with an oxygen supply pipe 404, one end of the third connecting pipe 403 away from the first connecting pipe 401 is connected with the oxygen supply pipe 404, and the side wall of the oxygen supply pipe 404 is provided with a plurality of oxygen outlet pipes 405 which are arranged in an inclined manner, and each oxygen outlet pipe 405 is provided with a stirring assembly for mixing and stirring oxygen.

[0026] It should be noted that: through the setting of the oxygen supply assembly, the oxygen content in the nutrient solution is increased, the oxygen absorption of the plant root system is maintained, the respiration of the plant root system is improved, the active absorption of nutrients by the plant root system is improved, and the risk of rotting of the plant root system due to oxygen deficiency is reduced, thereby further ensuring the growth and development of the plant.

[0027] Please refer to Figure 4 , the two supporting frames 102 close to the first connecting pipe 401 are provided with a fan 406, the output end of the fan 406 is connected with the supporting rod 103, the supporting rod 103 is provided in a hollow manner, and each second connecting pipe 402 is provided in communication with the inside of the supporting rod 103;

[0028] It should be noted that: through the setting of the fan 406, external gas is delivered to the inside of the supporting rod 103, and the air inlet end of the fan 406 is provided with a filter screen.

[0029] It should be noted that: the model of the fan 406 is FUMF-25, which is prior art and will not be described in detail here.

[0030] Please refer to Figure 4 and Figure 5 , the stirring assembly in the drawing includes a stirring box 501 fixedly connected to the oxygen outlet pipe 405 away from the oxygen supply pipe 404, the side of the stirring box 501 away from the oxygen outlet pipe 405 is fixedly connected with an output pipe 502, the side wall of the stirring box 501 is rotatably connected with a rotating shaft 503, the side wall of the rotating shaft 503 is provided with a plurality of stirring blades 504, and the stirring box 501 is provided with a driving assembly for driving the stirring blades 504;

[0031] It should be noted that: through the setting of the stirring assembly, under the action of the driving assembly, the oxygen sprayed from the output pipe 502 is mixed and stirred, the mixing amount of oxygen in the nutrient solution is increased, at the same time, the rotation of the stirring blades 504 can also stir the nutrient solution, thereby reducing the probability of precipitation of the nutrient solution, and further maintaining the uniformity of nutrient mixing in the nutrient solution.

[0032] It is worth noting that the stirring blade 504 is at a certain angle and distance from the planting dish 106, so as to avoid the rotation of the stirring blade 504 affecting the roots of the plants.

[0033] Please refer to Figure 5 , the output pipe 502 in the figure is provided with a one-way valve 505, and the conduction direction of the one-way valve 505 is from the inside to the outside of the stirring box 501;

[0034] It should be noted here that the one-way valve 505 is provided and the conduction direction is limited to prevent the nutrient solution from flowing into the stirring box 501.

[0035] Working principle: when the agricultural planting frame is used, the plants are first placed in the planting dish 106, and the absorption of the plant roots to the nutrient solution in the planting box 105 realizes the soilless cultivation growth of the plants, and when the plants are supplied with nutrients by the nutrient solution, one of the water pumps in the liquid storage tank 2 is started to push the nutrient solution to the infusion pipe 3, and the multiple branch pipes are used to deliver the nutrient solution to the planting box 105. During the process of delivering the nutrient solution, the other water pump in the liquid storage tank 2 is started to suck the excess nutrient solution in each planting box 105 back to the liquid storage tank 2, and a filter screen is installed in the infusion pipe 3 for the return flow of the nutrient solution, thereby filtering the return flow of the nutrient solution. Therefore, while realizing the supply of nutrient solution to the plants, the circulation of the nutrient solution is realized, thereby keeping the flowability of the nutrient solution at all times, so as to realize the economical use of the nutrient solution and reduce the risk of deterioration of the nutrient solution;

[0036] When the plants are supplied with nutrient solution, the fan 406 is started, the external air is delivered from the support rod 103 to the second connecting pipe 402 by the fan 406, and then delivered to the oxygen supply pipe 404 through the first connecting pipe 401 and the third connecting pipe 403, and finally flows from the output pipe 502 on the side of the oxygen outlet pipe 405 to the inside of the nutrient solution, thereby increasing the oxygen content in the nutrient solution and maintaining the oxygen absorption amount of the plant roots, so as to improve the respiration of the plant roots and improve the active absorption of nutrients by the plant roots and reduce the risk of rotting of the plant roots due to lack of oxygen, thereby further ensuring the growth and development of the plants;

[0037] When the plant roots are supplied with oxygen, the driving assembly drives the stirring blade 504 to rotate, thereby mixing and stirring the oxygen sprayed from the output pipe 502, increasing the mixing amount of oxygen in the nutrient solution. At the same time, the rotation of the stirring blade 504 can also stir the nutrient solution, thereby reducing the probability of precipitation of the nutrient solution and further maintaining the uniformity of the nutrient mixture in the nutrient solution. Embodiment 2

[0038] Referring to Figure 5 The embodiment is further illustrated by Example 1. In the diagram, the driving assembly includes a driving shaft 601 rotatably connected to the stirring box 501. The driving shaft 601 is eccentrically arranged with the oxygen outlet pipe 405. One end of the driving shaft 601 is connected to the rotating shaft 503. The side wall of the driving shaft 601 is fixedly connected with a plurality of driving vanes 602.

[0039] It should be noted that, through the arrangement of the driving assembly, when the oxygen flows from the stirring box 501, the driving vanes 602 on the side wall of the driving shaft 601 will be rotated due to the eccentric arrangement of the driving shaft 601 and the oxygen outlet pipe 405, thereby driving the rotating shaft 503 at one end of the driving shaft 601 to rotate.
