Description

Technical Field

[0001] This utility model relates to the field of rice breeding, and more particularly to a seed soaking and germination device for rice breeding. Background Technology

[0002] Seed germination is a crucial step in rice cultivation, directly impacting seedling emergence rate, growth rate, and yield. Effective germination ensures rapid and uniform seed sprouting, laying a solid foundation for rice growth. This typically involves soaking the seeds in warm water for a period, utilizing the heat to promote water absorption and initiate the germination process. For example, farmers may use their hands to check the water temperature, maintaining it at approximately 40°C, and then soak the seeds for one to two days.

[0003] Seeds require dynamic changes in temperature and humidity at different stages. Existing technologies involve soaking and germinating seeds in different equipment, which increases the cost of germination. This invention solves the above problems. Utility Model Content

[0004] In order to address the technical problem that existing technologies involve soaking and germinating seeds in different devices, which increases the cost of germination, this invention provides a seed soaking and germination device for rice breeding.

[0005] A rice seed soaking and germination device for breeding includes: a germination chamber, which is a container arranged vertically along its length; a pulley shaft is rotatably mounted inside the upper and lower side walls of the germination chamber; a pulley is connected to the inner end of the pulley shaft; the upper and lower pulleys are connected by a belt; two sets of belt drives are close to the inner side walls of the germination chamber on the corresponding sides; the two sets of belt drives operate synchronously; multiple breaks are evenly distributed on the belt; a rubber sleeve is connected to the break of the belt; the rubber sleeve has holes; a mesh frame is slidably connected inside the rubber sleeve; rice seeds are placed inside the mesh frame; nutrient solution is contained in the lower part of the germination chamber; a filling port is opened in the middle of the germination chamber; and a sealing door that can be opened and closed is installed in the filling port.

[0006] Furthermore, an air inlet pipe is connected above the nutrient solution surface at the bottom of the germination chamber, and the air inlet pipe is connected to an air pump. An exhaust pipe is connected to the top of the germination chamber, and a drain pipe is connected to the bottom wall of the germination chamber. Valves are installed in the air inlet pipe, the exhaust pipe, and the drain pipe.

[0007] Furthermore, the upper pulley shafts of the two sets of belt drives are both connected to gear one, gear one meshes with gear two, both gear two are connected to gear shaft, the gear shaft is rotatably connected in bearing housing, the bearing housing is connected to the top wall of the germination chamber, and the gear shaft is connected to the power source.

[0008] The beneficial effects of this utility model are:

[0009] 1. Changing the traditional static soaking method, dynamic soaking technology is adopted. Through two sets of synchronously operating belt drives, the rice seeds in the mesh are fully in contact with the air while being soaked, eliminating the need to change the germination container and greatly improving the germination rate.

[0010] 2. During ventilation, air enters from the bottom and exits from the bottom, maximizing the removal of gases from the germination chamber and resulting in good ventilation. Attached Figure Description

[0015] 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.

[0016] The rotary connection described in this device refers to the axial fixation of the bearing by mounting the bearing on the shaft, with a spring retaining ring groove provided on the shaft or shaft hole, and the rotation achieved by locking the elastic retaining ring in the retaining ring groove; the hinge connection refers to the connection method that allows movement through connecting parts such as hinges, pins, and short shafts.

[0017] The present invention will now be described in detail with reference to the accompanying drawings.

[0018] Example 1:

[0019] The following is in conjunction with the appendix Figure 1-3This embodiment describes a rice seed soaking and germination device, comprising: a germination chamber 1, which is a container arranged vertically along its length; a pulley shaft 2 is rotatably mounted on the upper and lower side walls of the germination chamber 1; a pulley 3 is connected to the inner end of the pulley shaft 2; the upper and lower pulleys 3 are connected by a belt 4; both belt drives are close to the inner side walls of the germination chamber 1 on the corresponding side; the two belt drives operate synchronously; multiple breaks are evenly distributed on the belt 4; a rubber sleeve 5 is connected to the break of the belt 4; the rubber sleeve 5 has holes; a mesh frame 6 is slidably connected inside the rubber sleeve 5; rice seeds are placed inside the mesh frame 6; nutrient solution is contained in the lower part of the germination chamber 1; a filling port 7 is opened in the middle of the germination chamber 1; and a sealing door 8 that can be opened and closed is installed inside the filling port 7.

[0020] During use, after the nutrient solution is injected into the lower part of the germination chamber 1, the mesh frame 6 holding the seeds is placed inside the rubber sleeve 5. The rubber sleeve 5 is supported by the mesh frame 6 and will not deform, making the belt drive stable. The sealing door 8 is closed, and the temperature control component inside the germination chamber 1 is turned on to adjust the temperature. The two sets of belt drive power are turned on, and the power drives the belt 4 through the pulley shaft 2. The belt 4 drives the rubber sleeve 5, and the rubber sleeve 5 drives the mesh frame 6. The mesh frame 6 carries the seeds into the nutrient solution in the lower part of the germination chamber 1. At this time, the belt drive speed can be slowed down to increase the initial soaking time of the rice seeds. After the rice seeds are fully soaked, they float to the surface and come into full contact with the air. There is no need to change the germination container, which greatly improves the germination rate. After the rice seeds are fully soaked, the belt drive is kept running at a constant speed to maintain the moisture of the rice seeds, which can steadily improve the germination rate.

[0021] An air inlet pipe 9 is connected above the nutrient solution surface at the bottom of the germination chamber 1. The air inlet pipe 9 is connected to an air pump. An exhaust pipe 10 is connected to the top of the germination chamber 1. A drain pipe 11 is connected to the bottom wall of the germination chamber 1. Valves are provided in the air inlet pipe 9, the exhaust pipe 10, and the drain pipe 11.

[0022] During ventilation, the air pump injects air through the air inlet pipe 9 and opens the inner valve of the exhaust pipe 10, allowing air to exit from the upper exhaust pipe 10. This maximizes the removal of gas from the germination chamber, resulting in good ventilation and increased germination rate.

[0023] The upper pulley shafts 2 of the two belt drives are connected to gear 12. Gear 12 meshes with gear 2 13. Both gears 2 13 are connected to gear shaft 14. Gear shaft 14 is rotatably connected in bearing seat 15. Bearing seat 15 is connected to the top wall of germination chamber 1. Gear shaft 14 is connected to the power source.

[0024] The power drives the gear shaft 14 to rotate, and the gear shaft 14 drives the corresponding pulley shafts 2 on both sides to rotate through two sets of gears 12 and 13, ensuring that the two sets of belt drives operate synchronously.
