Description

Technical Field

[0001] This utility model relates to the field of seed germination technology, and in particular to a seed germination device for crop cultivation. Background Technology

[0002] Crop cultivation is an important part of agricultural production, and seed germination treatment is an indispensable step in crop cultivation. Germination refers to the artificial control of environmental conditions, such as temperature, humidity and light, to promote seed germination in a shorter period of time, thereby shortening the growth cycle and improving the yield and quality of crops.

[0003] Existing germination devices cannot ensure that the temperature, air, and humidity of the germination environment are all within a suitable range at the same time during the seed germination process. This makes it difficult for the seeds to achieve the best germination effect, which may adversely affect the survival or growth of the seeds. An existing patent (publication number: CN221576021U) discloses a seed germination device for watermelon cultivation. A fan assembly delivers air heated by an electric heating wire assembly into the chamber, ensuring a warm and oxygen-rich environment suitable for germination. The power of the heating wire assembly controls the amount of heat generated per unit time, maintaining and regulating the temperature. A temperature sensor monitors the chamber temperature and adjusts the power of the heating wire assembly accordingly. Simultaneously, a humidity sensor monitors the moisture in the outflowing air to determine the humidity inside the chamber. When the humidity is low, a nozzle sprays a fine water mist, which, carried by the airflow, fills the chamber, increasing humidity. This ensures that the temperature, oxygen, and humidity of the seed germination environment are all within a suitable range, resulting in better germination, higher seed survival rates, and improved seed growth.

[0004] To address the aforementioned issues, existing patents have provided solutions, but they cannot maintain moisture during seed cultivation. Existing germination devices can only keep the soil surface moist, but cannot keep the bottom of the soil moist, thus failing to simulate the effect of seeds absorbing water from the soil during natural growth.

[0024] Specifically, such as Figure 5 As shown, a support ring 8 is fixedly connected to the inner wall of the mounting cup 52, the bottom of the cultivation cover 54 contacts the support ring 8, and the cultivation cover 54 is threadedly connected to the mounting cup 52.

[0025] Specifically, such as Figure 5 As shown, a dividing mesh 9 is provided at the top of the support ring 8, and the side wall of the dividing mesh 9 is in contact with the inner wall of the cultivation cover 54.

[0026] Specifically, such as Figure 1 As shown, two doors 12 are hinged to the side wall of the germination box 1, and a transparent window 13 is provided in the middle of the door 12.

[0027] In use, the moisture-retaining germination mechanism 5 mainly consists of a moisture-retaining cup 51, an installation cup 52, a cultivation cover 54, and a soil moisture-retaining component 57. The moisture-retaining cup 51 is fixed to the top of the cultivation board 4 and contains the installation cup 52. The bottom of the installation cup 52 has a connecting groove 53 to allow water to seep down. The cultivation cover 54 is installed on top of the installation cup 52 and has a drainage hole 55 on its top to prevent water accumulation. The absorbent cotton 56 at the bottom of the installation cup 52 can absorb and retain moisture, providing the necessary humidity environment for the seeds.

[0029] Specifically, such as Figure 2As shown, a heating frame 10 is provided on the side wall of the mounting bracket 68, and a plurality of electric heating wires 11 are provided on the inner wall of the heating frame 10.

[0030] In use, when the first electric push rod 67 extends or retracts, it drives the drive plate 65 through the connecting plate 66, which in turn drives the movable block 64 and the adjusting plate 62 to slide within the sliding frame 61, changing the size of the ventilation opening. A mounting frame 68 is also fixed inside the ventilation hood 2, and two sets of fans 69 are bolted inside the mounting frame 68 to accelerate airflow and improve ventilation efficiency. A heating frame 10 is also provided on the side wall of the mounting frame 68, and multiple electric heating wires 11 are provided on the inner wall of the heating frame 10 to provide additional heat when needed to regulate the temperature environment inside the germination chamber 1. This accelerates airflow, improves ventilation efficiency, ensures the freshness and oxygen content of the air inside the germination chamber 1, which is beneficial for rapid seed germination. It also provides additional heat when needed to regulate the temperature environment inside the germination chamber 1, keeping it within a suitable range, which is beneficial for seed growth and germination.

[0031] By adopting the above technical solution, the problems of existing seed germination devices being unable to keep cultivated seeds moist during planting, unable to keep the bottom of the soil moist, and unable to simulate the effect of seeds absorbing water from the soil under natural growth conditions have been solved.
