Technical Field

[0001] This utility model relates to the field of vegetable seedling technology, specifically to a vegetable seedling germination device. Background Technology

[0002] Vegetable seedling raising and germination is a crucial step in the vegetable planting process. Its purpose is to promote rapid and uniform germination of seeds by artificially controlling environmental conditions, thereby improving the germination rate and seedling quality, and laying a good foundation for the subsequent growth of vegetables.

[0003] Current vegetable seedling germination devices rely solely on simple water spraying mechanisms, which cannot guarantee uniform humidity distribution within the cabinet. Humidity varies between locations near and far from the humidifier, resulting in uneven seed germination. Vegetables also have different carbon dioxide concentration requirements at different growth stages, with some vegetables being particularly sensitive to carbon dioxide concentrations. Current seedling devices struggle to dynamically adjust to the actual needs of the plants. Therefore, this paper proposes a new vegetable seedling germination device to address the aforementioned problems. Utility Model Content

[0013] The following description is intended to disclose the present invention so that those skilled in the art can implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.

[0014] Reference Figures 1-4 As shown, a vegetable seedling germination device includes a cabinet body 1 and a cabinet door 2. The cabinet door 2 is fixedly installed at the front end of the cabinet body 1. A guide plate 16 and a carbon dioxide sensor 17 are fixedly connected to the inner left side of the cabinet body 1. The guide plate 16 can evenly distribute the fresh air introduced by the air pump 9 and fan 12 to various areas inside the cabinet body 1, allowing the airflow to pass evenly through each layer of seedling trays 7. The carbon dioxide sensor 17 can be of model HH04-J2C, or other sensors that can achieve the same function. The cabinet body 1 and the cabinet door 2 are hinged together by a hinge 3. An observation window 14 is fixedly connected to the front end of the cabinet door 2. A handle 15 is fixedly installed below the observation window 14 at the front end of the cabinet door 2. A water storage tank 4 is fixedly installed at the bottom inner side of the cabinet body 1. A spraying mechanism 5 is provided inside the cabinet body 1. The spraying mechanism 5 includes an inlet pipe 501, a water pump 502, and an outlet pipe 503. The water tank 4 is connected to one end of an inlet pipe 501 at the right end. The other end of the inlet pipe 501 passes through the right end of the cabinet 1 and is fixedly connected to a water pump 502. The output end of the water pump 502 is connected to an outlet pipe 503. The side of the outlet pipe 503 near the cabinet 1 is connected to one end of multiple water distribution pipes 504. When the water pump 502 is turned on, the water in the water tank 4 is pumped into the outlet pipe 503 through the inlet pipe 501 and then distributed to each water distribution pipe 504. The other ends of the multiple water distribution pipes 504 extend into the interior of the cabinet 1 and are fixedly connected to the atomizing nozzle assembly 505. By using the spraying mechanism 5 to cover each layer of seedling pots 7 and using the atomizing nozzle assembly 505 to spray water evenly in the seedling pots 7, the atomization effect is improved and the spraying range is expanded, improving the uniformity of spraying, so that each seedling can get enough water and promote its growth. Furthermore, the atomizing nozzle assembly 505 includes a nozzle frame 5051, an upper nozzle 5052, a refraction cone 5053, a rotating disk 5054, a rotating shaft 5055, an impeller 5056, a connector 5057, and a lower nozzle 5058. The upper nozzle 5052 is fixedly connected to the top of the nozzle frame 5051, and the top of the upper nozzle 5052 is fixedly connected to the other end of the water distribution pipe 504. The refraction cone 5053 is located directly below the upper nozzle 5052. 053 is typically used to change the direction of water flow, allowing the water to be evenly distributed on the rotating disk 5054, thus increasing the atomization effect of the water flow. The upper end of the rotating shaft 5055 passes through the central hole of the rotating disk 5054 and is fixedly connected to it. The top of the rotating shaft 5055 is fixedly connected to the refraction cone 5053. The impeller 5056 is fixed in the middle section of the rotating shaft 5055, located between the rotating disk 5054 and the lower nozzle 5058. The rotating shaft 5055 and the lower nozzle 5058 are kept at 0°.With a gap of 5mm or more, the water flow is initially atomized by the upper nozzle 5052, impacting the refraction cone 5053 for diffusion. The water flow drives the impeller 5056 to rotate, thereby driving the rotating shaft 5055 to rotate, making the refraction cone 5053 rotate synchronously and enhancing the uniformity of atomization. The remaining water flow is atomized again by the lower nozzle 5058, spraying the seedling tray 7. The connector 5057 is fixedly connected to the bottom end of the nozzle frame 5051 and rotatably connected to the rotating shaft 5055. The connector 5057 has a bearing inside, and the lower end of the rotating shaft 5055 is interference-fitted with the inner ring of the bearing. The lower nozzle 5058 is fixedly installed on the connector 505. At the bottom of cabinet 7, above the water storage tank 4, there are multiple support frames 6. If the demand for carbon dioxide is large, a carbon dioxide generator is installed on the support frame 6 to work with carbon dioxide 17 to achieve the required carbon dioxide concentration. All support frames 6 are fixedly connected to the inner wall of cabinet 1. Seedling pots 7 are placed on the top of each support frame 6. Open cabinet door 2, inject an appropriate amount of clean water into water storage tank 4, place the seedling pots 7 after sowing on the support frame 6, close cabinet door 2 with handle 15, and check the internal situation through observation window 14. A fixed base 8 is set on the left side of cabinet 1, and the top of the fixed base 8 is fixed. An air pump 9 is fixedly connected to the cabinet 1. The output end of the air pump 9 is connected to one end of an air inlet pipe 10. The other end of the air inlet pipe 10 passes through the left end of the cabinet 1 and is positioned above the water storage tank 4. Multiple motors 11 are fixedly installed on the left end of the cabinet 1 above the air inlet pipe 10. The output ends of the multiple motors 11 all pass through the left end of the cabinet 1 and are fixedly connected to fans 12. An air outlet pipe 13 is fixedly connected to the top of the cabinet 1. Through the cooperation of the air pump 9 and the fans 12, carbon dioxide is evenly distributed to all corners of the cabinet 1 to avoid local concentrations that are too high or too low. A carbon dioxide sensor 17 is connected to the air pump 9 and the solenoid valve 18. The combined operation of the air pump 9 and the solenoid valve 10 ensures that the carbon dioxide content inside the cabinet 1 meets the needs of the vegetables, improving the efficiency and quality of vegetable seedling cultivation. A solenoid valve 18 is fixedly connected to the outside of the air outlet pipe 13. When the air pump 9 is started, external gas enters the cabinet 1 through the air inlet pipe 10. The motor 11 is turned on, driving the fan 12 to blow air upwards. The airflow, guided by the guide plate 16, is evenly distributed through the gaps in the seedling trays 7 and finally discharged through the top air outlet pipe 13. The carbon dioxide content inside is detected by the carbon dioxide sensor 17, which then controls the opening and closing of the air pump 9 and the solenoid valve 18 to maintain the carbon dioxide concentration inside the cabinet 1 at the required level.

[0015] The usage process of this utility model is as follows: First, open the cabinet door 2, inject an appropriate amount of clean water into the water storage tank 4, place the seedling pot 7 after sowing on the support frame 6, close the cabinet door 2 through the handle 15, and check the internal situation through the observation window 14. Turn on the water pump 502 to pump the water in the water storage tank 4 into the water outlet pipe 503 through the water inlet pipe 501, and then distribute it to each water distribution pipe 504. The water flow is initially atomized by the upper nozzle 5052, impacting the refraction cone 5053 for diffusion. The water flow drives the impeller 5056 to rotate, thereby driving the rotating shaft 5055 to rotate, so that the refraction cone 5053... 53 Synchronous rotation enhances atomization uniformity. The remaining water flow is atomized a second time through the lower nozzle 5058 to spray the seedling tray 7. Then, the air pump 9 is started, and external gas enters the cabinet 1 through the air inlet pipe 10. The motor 11 is turned on, driving the fan 12 to blow air upward. With the help of the guide plate 16, the airflow is guided to pass evenly through the gaps in the seedling tray 7 and finally discharged through the top air outlet pipe 13. The carbon dioxide content inside is detected by the carbon dioxide sensor 17, and then the opening and closing of the air pump 9 and the solenoid valve 18 are controlled to maintain the carbon dioxide inside the cabinet 1 at the required concentration.
