[0002] Rice is divided into indica rice and japonica rice, early rice and mid-late rice, glutinous rice and non-glutinous rice according to the type of rice grains. The grains of rice are called paddy rice. The rice grains are called brown rice after the husks are removed. The rice is obtained by grinding away the bran layer of brown rice. The germination rate of rice seeds needs to be tested before they are cultivated or planted. Nearly half of the world's population relies on rice as their staple food.

The ends are connected with the fan 4, the surface of the insert pipe 16 is slidably arranged inside the top of the air outlet pipe 15, a disc 19 is rotatably installed inside the incubator 1, a movable rod 20 is rotatably installed on the outer edge of the side of the disc 19, and the other end of the movable rod 20 is rotatably installed on the bottom of the connecting plate 17, a second bevel gear 11 is meshed with the side of the first bevel gear 10, a rotating shaft 12 is horizontally rotatably installed on the outer side of the incubator 1, a second one-way bearing 32 is sleeved at the end of the rotating shaft 12, the second bevel gear 11 is fixedly sleeved on the outer ring of the second one-way bearing 32, and the end of the rotating shaft 12 is fixedly installed at the center of the side of the disc 19 through a connecting shaft;

[0040] Preferably, the carbon dioxide content inside the incubator 1 can be detected. Since the rice seeds will respire when germinating, the rice seeds will produce carbon dioxide during respiration. The sodium hydroxide and carbon dioxide inside the box body 23 react to generate sodium bicarbonate, which will increase the weight of the box body 23. Further, the germination rate of the rice seeds can be obtained by detecting the total weight of the box body 23.

[0041] The working principle of the present invention is as follows: firstly, the rice seeds are placed inside the cultivation box 2 and the door is closed. When the cultivation is carried out, the outside air can enter the cultivation box 1 through the polymer membrane 3. The polymer membrane 3 is used to separate carbon dioxide, so that the carbon dioxide inside the cultivation box 1 is all produced by the respiration of the germination of the rice seeds. When the germination rate needs to be detected at the designated time of cultivation of the rice seeds inside the cultivation box 1;

[0042] The solenoid valve is opened to allow the sodium hydroxide in the box body 31 to be quantitatively added to the corresponding box body 23 through the liquid pipe. At this time, the box body 23 has a weight, and the weight is constant, and the weight is recorded as A. Then the drive motor 7 is started, so that the drive motor 7 rotates 90 degrees forward to drive the first bevel gear 10 to rotate. The rotation of the first bevel gear 10 not only drives the rotating rod 8 to rotate through the first one-way bearing 9, but also drives the second bevel gear 11 to rotate. Due to the setting of the second one-way bearing 32, the second one-way bearing 32 will not drive the rotating shaft 12 to rotate at this time. The rotating rod 8 rotates the turntable 13 to rotate, and the rotation of the turntable 13 drives the four box bodies 23 to rotate and change positions. Then the box body 23 with sodium hydroxide rotates to the inside of the incubator 1, and the box body 3 1, the sodium hydroxide inside is continuously quantitatively added into the box body 23 through the liquid pipe, and then the driving motor 7 is reversed 180 degrees to drive the first bevel gear 10 to reverse. Due to the setting of the first one-way bearing 9, the rotating rod 8 will not rotate at this time, and the second one-way bearing 32 will drive the rotating shaft 12 to rotate, and the rotation of the rotating shaft 12 drives the disc 19 to rotate. It should be noted that the contact surface between the disc 19 and the inside of the incubator 1 is a rough surface. The rotation of the disc 19 drives the movable rod 20 to move, and the movement of the movable rod 20 drives the connecting plate 17 to move, and the movement of the connecting plate 17 drives the cannula 16 to move upward, so as to insert the cannula 16 into the end of the tube body 25. Then, the fan 4 is turned on, and the fan 4 will blow the liquid inside the incubator 1. The gas is drawn into the air outlet pipe 15 through the air inlet pipe 14, and the gas inside the air outlet pipe 15 enters the sodium hydroxide liquid through the insert pipe 16 and the tube body 25, and the sodium hydroxide reacts with the carbon dioxide in the gas to generate sodium bicarbonate, which further increases the weight of the box body 23. After the reaction of the carbon dioxide inside the incubator 1 is completed, the drive motor 7 is reversed 180 degrees again, and the rotation of the disc 19 will drive the insert pipe 16 to move downward to the starting position. It should be noted that when the insert pipe 16 and the tube body 25 are separated, the box body 23 will move downward under the action of gravity, and when the turntable 13 rotates, due to the setting of the groove 24, the box body 23 will enter the through groove 28, and then the drive motor 7 will rotate 180 degrees. 7 is rotated forward 90 degrees, and the box body 23 with sodium bicarbonate will be transferred to the bottom groove 22 and weighed on the weighing plate 21. In summary, at this time, the carbon dioxide inside the incubator 1 has been reacted with the sodium hydroxide in the previous box body 23. At this time, the carbon dioxide generated inside the incubator 1 can be reacted by the fan 4 within the specified time. The carbon dioxide generated at this time is generated by the respiration of the germinated rice seeds. In summary, the driving motor 7 is rotated forward again, and the weighed box body 23 is rotated to the top groove 6 for cleaning, and the box body 23 that reacts with the carbon dioxide inside the incubator 1 is transferred to the weighing station for weighing, and the weight is recorded as B. Then the germination rate of the rice seeds is calculated by the calculation formula, and the calculation formula is: Where a is the weight of sodium bicarbonate produced by the reaction of carbon dioxide and sodium hydroxide within a specified time after a rice seed germinates, then a is a known constant, x is the number of germinated rice seeds,

[0043] In summary, the germination rate of rice seeds can be tested by repeating the above steps in sequence, and the detection is convenient and quick, thereby improving the use effect of the equipment.

[0044] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
