Description

Technical Field

[0001] This utility model relates to the field of soilless seedling technology, and in particular to a soilless seedling device for agricultural use. Background Technology

[0002] Seedling cultivation technology refers to the process of cultivating seeds or seedlings into seedlings in a suitable environment through artificial methods, so as to provide strong plants for subsequent cultivation or transplantation. Seedling cultivation technology is widely used in the fields of agriculture, forestry and horticulture. Common seedling cultivation methods include soil seedling cultivation, hydroponic seedling cultivation and air layer cultivation.

[0003] Hydroponic cultivation and air layer cultivation are both soilless seedling cultivation methods. Soilless seedling cultivation is a method of cultivating seedlings without using natural soil, but using nutrient solutions or other substrates. In traditional soil seedling cultivation, the soil may carry various pathogens, pests, and weed seeds. For example, Fusarium or root-knot nematodes in the soil can infect the seedling roots, leading to poor seedling growth or even death. The substrate used in soilless seedling cultivation is usually disinfected, which can effectively reduce the spread of these pests and diseases and provide a relatively clean growing environment for seedlings.

[0004] The supply, concentration, and pH control of nutrient solution are crucial for soilless seedling cultivation. However, some existing seedling devices are not precise enough in supplying nutrient solution, resulting in uneven nutrient supply. The current solution involves manual mixing in the machine before injecting it into the seedling device. This makes it impossible to adjust the composition and concentration of the nutrient solution in a timely manner according to the growth status of the seedlings and changes in the environment. Consequently, some seedlings may receive excessive or insufficient nutrients, which affects the cultivation effect of the seedling device. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a soilless seedling raising device for agriculture, which aims to improve the problem in the existing technology that cannot adjust the composition and concentration of nutrient solution in a timely manner according to the growth status and environmental changes of seedlings, resulting in some seedlings having excessive or insufficient nutrition, thus affecting the cultivation effect of the seedling raising device.

The inner wall of the left rubber ring is fixedly connected to the right end of the outer wall of the connecting pipe, and the inner wall of the right rubber ring is fixedly connected to the left end of the outer wall of the conveying pipe.

Then, the airflow is injected into the interior of the mixing tank through the delivery pipe and the multi-hole nozzle. The delivered airflow drives the liquid inside the mixing tank to mix and stir, thereby improving the mixing efficiency of the nutrient solution and shortening the preparation time required for cultivation.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Reference Figure 1 , Figure 2 and Figure 4 This utility model provides an embodiment of a soilless seedling raising device for agriculture, including a fixed platform 1. The fixed platform 1 connects a double-layer frame 3 to a culture box 12. The top wall of the fixed platform 1 is fixedly connected to the double-layer frame 3, which fixes the mixing tank 4. The inner wall of the double-layer frame 3 is fixedly connected to the mixing tank 4, which mixes nutrients and water. Electric push rods 5 are fixedly connected to the left and right sides of the top wall of the double-layer frame 3. When the electric push rods 5 are activated, the lifting plate 6 moves up and down. The top of the electric push rod 5 is fixedly connected to the lifting plate 6, which in turn drives the injection rod 7 to move up and down, so that the liquid in the metering tank 8 is injected into the mixing tank 4. The bottom wall of the lifting plate 6 is fixedly connected to the injection rod 7. The inner top wall of the double-layer frame 3 is fixedly connected to the metering tank 8 on both the left and right sides. The bottom of the container has a one-way valve, and the liquid is injected in one direction by raising and lowering the injection rod 7. The bottom end of the injection rod 7 is slidably connected to the inner wall of the metering tank 8. The rear side of the metering tank 8 is connected to the injection valve 9, so that the nutrient solution and water are poured into the metering tank 8 under the connection of the injection valve 9. The bottom ends of the two metering tanks 8 are connected to the top wall of the mixing tank 4. The left and right ends of the front side of the mixing tank 4 are connected to the solenoid valve 11, which is used to inject the mixed nutrient solution into the incubation box 12. The incubation box 12 is fixedly connected to the front side of the fixed platform 1, and waterless seedling cultivation is carried out through the incubation box 12. Multiple substrate boards 13 are fixedly connected to the inner bottom wall of the incubation box 12, which support the seedlings. A mixing mechanism 2 is set on the left side of the double-layer frame 3. The mixing mechanism 2 is used to improve the mixing efficiency of the nutrient solution.

[0033] Reference Figure 1 , Figure 3 and Figure 5 The mixing mechanism 2 includes a blower 201, which draws in and transports outside air. A connecting pipe 202 connects to the rear of the blower 201, allowing the drawn airflow to first enter the processing chamber 203 for processing. The right end of the connecting pipe 202 connects to the processing chamber 203. A filter plate 204 is slidably connected to the middle of the inner wall of the processing chamber 203. The airflow first passes through the filter plate 204, effectively removing dust particles. An adsorption sponge 205 is fixedly connected to the right side of the inner wall of the processing chamber 203, further drying and filtering under the adsorption of the sponge 205. A conveying pipe 206 connects to the right side of the processing chamber 203, with a multi-hole nozzle 207 connected to the front end of the conveying pipe 206, thus allowing the filtered air to pass through the filter. The liquid is sprayed through the conveying pipe 206 via the multi-hole nozzle 207. The front side of the multi-hole nozzle 207 is connected to the rear side of the mixing tank 4, thereby achieving the effect of injecting into the mixing tank 4 and driving the liquid solvent to mix. The mixing mechanism 2 also includes two rubber rings 208. The installation of the rubber rings 208 reduces the wear at the connection between the connecting pipe 202 and the conveying pipe 206 and the treatment box 203. The inner wall of the left rubber ring 208 is fixedly connected to the right end of the outer wall of the connecting pipe 202, and the inner wall of the right rubber ring 208 is fixedly connected to the left end of the outer wall of the conveying pipe 206. The top wall of the filter plate 204 is fixedly connected to a handle 17, and the middle part of the handle 17 is fixedly connected to a rubber sleeve 18, thereby improving the anti-slip effect of pulling the filter plate 204 through the handle 17 and the rubber sleeve 18.

[0034] Reference Figure 1 , Figure 4 and Figure 5 A control switch 14 is fixedly connected to the right side of the double-layer frame 3. The control switch 14 is electrically connected to the electric push rod 5, the solenoid valve 11, and the blower 201. The control switch 14, which is electrically connected to the electric push rod 5, the solenoid valve 11, and the blower 201, enables the device to be turned on and off. A sealing ring 10 is fixedly installed on the outer wall of each of the two injection valves 9. The outer wall of each of the two sealing rings 10 is fixedly connected to the rear side of the metering tank 8. The sealing ring 10 improves the sealing between the injection valve 9 and the metering tank 8. Multiple substrate boards 13 are arranged symmetrically at equal intervals. The equidistant arrangement improves the uniformity of nutrient absorption during seedling cultivation. The two lifting plates 6 are both designed in a Z-shape. Connecting seats 15 are fixedly connected to the left and right sides of the fixed platform 1. The top of each connecting seat 15 is provided with an installation groove 16. The connecting seats 15 and the installation groove 16 facilitate the fixing and installation of the device, improving the stability of the device.

[0035] Working principle: At the beginning of use, the nutrient solution and water are injected into the metering tank 8 through the injection valve 9. Then, by activating the electric push rod 5, the top of the electric push rod 5 drives the lifting plate 6 to move up and down. The lifting plate 6 then moves the injection rod 7 downward, and the injection rod 7 slides inside the metering tank 8. The bottom of the injection rod 7 pushes the liquid to inject, thus accurately injecting the nutrient solution or water into the mixing tank 4, thereby achieving the purpose of metered nutrient solution preparation. After mixing, the solvent is sent into the incubation box 12 through the opening of the solenoid valve 11, so as to achieve the effect of adjusting the composition and concentration of the nutrient solution according to the growth status of the seedlings, reducing the impact on the seedling effect.

[0036] Furthermore, by starting the blower 201, it draws in outside air and delivers it into the processing tank 203 through the connecting pipe 202. The airflow then passes through the filter plate 204 and the adsorption sponge 205 to filter and remove impurity particles. Subsequently, the filtered airflow is sprayed through the delivery pipe 206 and the multi-hole nozzle 207, allowing the sprayed airflow to enter the interior of the mixing tank 4. This causes the liquid inside the mixing tank 4 to be mixed and stirred, achieving a uniform mixing effect. This improves the mixing efficiency of the nutrient solution and shortens the preparation time required for cultivation.

[0037] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
