Detailed Implementation
[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.
[0022] like Figure 1 As shown, a rice seed germination device includes: a cultivation tray 1 for placing rice seeds, the cultivation tray 1 having a rolling cover 11; a soaking tank 2 for holding the cultivation tray 1; a temperature control tank 3 located below the soaking tank 2; a spraying mechanism 4 located inside the temperature control tank 3; a ventilation mechanism 5 located on the side wall of the temperature control tank 3; and an auxiliary rolling mechanism 6 located inside the temperature control tank 3.
[0023] Before the rice seeds germinate, spread them evenly on a cultivation tray 1. The cultivation tray 1 is made of a permeable material, allowing water entering from above to seep downwards. Figure 2 As shown, the tumbling cover 11 is detachably connected to the top of the cultivation tray 1. An L-shaped plate is provided on the top of the side wall of the tumbling cover, which rests on top of the cultivation tray 1. The tumbling cover 11 has ventilation holes 111 for the rice seeds, allowing water to enter the cultivation tray 1 through the ventilation holes 111. The tumbling cover 11 prevents the rice seeds from floating and overflowing during soaking. An auxiliary brush 12 is slidably connected to the tumbling cover 11 for tumbling the rice seeds. The auxiliary brush 12 contacts the upper surface of the rice seeds. As the brush slides along the tumbling cover 11, it changes the contact position between the rice seeds and the cultivation tray 1, facilitating more even heating and faster germination of the rice seeds.
[0024] The soaking tank 2 is larger than the cultivation tray 1. The side wall of the soaking tank 2 has a drain hole 21, which is controlled by a plug. During use, hot water at 40-42 degrees Celsius is poured into the soaking tank 2. Then, the cultivation tray 1, the rolling cover 11, and the rice seeds are immersed in the soaking tank 2 for 10 minutes to achieve high-temperature seed breaking. The soaked water is drained through the drain hole 21 and can be placed in the temperature control box 3 for continued use or discarded directly. In other embodiments, a heating rod is placed in the soaking tank 2 to heat the water to 40-42 degrees Celsius, directly heating the water in the soaking tank 2, which improves the soaking efficiency.
[0025] Temperature control chamber 3 is used to keep rice seeds warm after they have broken through the bud at high temperatures for germination. The rice seeds are placed in temperature control chamber 3 for about twenty hours. Figure 3As shown, the temperature control chamber 3 has a heating wire 31 at the bottom and culture water inside. The heating wire 31 continuously keeps the culture water warm, maintaining its temperature between 35-38°C, thus keeping the temperature inside the temperature control chamber 3 between 35-38°C. A mounting frame 32 is located in the middle of the temperature control chamber 3, and the cultivation tray 1 is slidably connected to the mounting frame 32. The mounting frame 32 is positioned above the culture water, thus preventing the rice seeds from being submerged. A rotatable sealing door 33 is rotatably connected to the temperature control chamber 3. The sealing door 33 is located outside the mounting frame 32, and its height is greater than that of the cultivation tray 1. The sealing door 33 is opened when installing or removing the cultivation tray 1 and closed when in the heat preservation state or not in use, reducing heat loss and overflow of the culture water.
[0026] An electronic thermometer 34 is installed on the side wall of the temperature control chamber 3. The display of the electronic thermometer 34 is located on the outer wall of the temperature control chamber 3. The electronic thermometer 34 monitors the temperature in the temperature control chamber 3 in real time to ensure that the temperature in the temperature control chamber 3 meets the germination conditions of rice seeds.
[0027] After maintaining the temperature at 35-38 degrees Celsius for about 20 hours in incubator 3, adjust the temperature of the culture water to 25-28 degrees Celsius so that the rice seeds can germinate and grow at 25-28 degrees Celsius.
[0028] The spraying mechanism 4 atomizes the culture water and sprays it onto the surface of the rice seeds, moistening them with water mist and promoting faster germination in a humid environment. The spraying mechanism 4 includes a water pump 41, a water intake pipe 42, a water outlet pipe 43, and a spray pipe 44. The water intake pipe 42 is placed in the culture water. The water pump 41 connects the water intake pipe 42 and the water outlet pipe 43. The spray pipe 44 is connected to the water outlet pipe 43. After the water pump 41 is started, it draws the heated culture water upwards, circulating the culture water and thereby keeping the temperature in the temperature control chamber 3 constant and reducing the temperature difference in the temperature control chamber 3.
[0029] The spray pipe 44 is located above the mounting frame 32. The spray pipe 44 is equipped with several atomizing nozzles 441. The atomizing nozzles 441 spray downwards at an angle. After spraying, the water vapor will adhere to the surface of the rice seeds, keeping the rice seeds moist, which is beneficial to the germination and sprouting of the rice seeds. The spray seeps out from the bottom of the cultivation tray 1 through the vent hole 111. The seeping water returns to the bottom of the temperature control box 3 and continues to participate in the water circulation in the temperature control box 3.
[0030] The ventilation mechanism 5 includes ventilation holes 51 and a fan 52. The ventilation holes 51 are located on both sides of the temperature control chamber 3, and the ventilation holes 51 on the side walls of the temperature control chamber 3 are arranged opposite each other. The fan 52 is located outside the ventilation holes 51. During heat preservation, the fan 52 keeps rotating to keep the air in the temperature control chamber 3 open to the outside, which facilitates the respiration of the rice seeds.
[0031] The auxiliary tumbling mechanism 6 is used to drive the auxiliary brush 12 to turn the rice seeds over. The auxiliary tumbling mechanism 6 includes a motor 61, a threaded rod 62, and a slider 63. The threaded rod 62 is located at the output end of the motor 61, and the slider 63 is screwed to the threaded rod 62. The temperature control box 3 is provided with a limit rod 35, and the slider 63 is slidably connected to the limit rod 35. The limit rod 35 restricts the slider 63 from turning over when moving. After the motor 61 is started, the slider 63 moves on the threaded rod 62.
[0032] The auxiliary brush 12 has a connecting block 121 on its upper part, and the slider 63 has a connecting groove 631. When installing the tumbling cover 11, the connecting block 121 is moved to the corresponding position of the connecting groove 631. After installing the cultivation tray 1, the connecting block 121 is inserted into the connecting groove 631. Then, when the slider 63 moves, it drives the auxiliary brush 12 to tumble the barley. The motor 61 starts every four to six hours to tumble the rice seeds. In other embodiments, the motor 61 is connected to a time relay to realize automatic start of the motor 61.
[0033] This device maintains the temperature in the temperature control chamber 3 at a suitable germination temperature by heating the cultivation water. While keeping the temperature warm, it sprays the surface of the rice seeds to maintain the temperature, and at the same time, the fan 52 keeps the air around the rice seeds circulating. During the heat preservation, the rice seeds are turned over by a rolling brush at regular intervals to stimulate the rice seeds to germinate quickly from all directions.
[0034] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the 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 this utility model should be included within the protection scope of this utility model.
