Description

Technical Field

[0001] This invention relates to the field of rice hybrid breeding technology, specifically to a device and method for rice hybrid breeding resistant to rice blast. Background Technology

[0002] China is one of the origins of rice. In southern China, farmland is predominantly paddy fields, with rice being the main grain crop. Rice is an important agricultural crop, and its cultivation requires specific natural and socio-economic conditions. In terms of natural conditions, rice needs sufficient water resources, a suitable climate, and suitable soil conditions. With the development of science and technology, rice breeding has formed a mature system. To improve the quality and efficiency of rice breeding, rice breeders use rice breeding boxes for cultivation. These boxes provide a suitable cultivation environment, unaffected by weather and external influencing factors, maximizing seed survival and germination rates.

[0003] Current rice breeding methods involve directly burying seeds in water, which can easily lead to seed death and affect the final cultivation rate. Furthermore, existing breeding equipment lacks a proper water supply system, making water replenishment very troublesome for rice breeders. They need to replenish water to the trays in the breeding box layer by layer, which often results in water leakage, causing great inconvenience to rice breeding work. Summary of the Invention

[0004] To solve the above-mentioned technical problems, the present invention is achieved through the following technical solution: a hybrid rice breeding device and method resistant to rice blast, comprising a shell, a cabinet door hinged to the front end of the shell, and a protective cover fixedly connected to the top of the shell; A rotating assembly, which is rotatably mounted inside the housing; The breeding component is mounted on the rotating component. The outer side of the breeding component is fixedly connected to a pipe. There are two pipes. The outer side of the pipe is provided with an extension tube. The extension tube is connected to the through holes on multiple cylinders. The top of one pipe is connected to the bottom of the connecting seat, and the bottom of the other pipe is fixedly connected to the top of the connecting seat. The two pipes are set on both sides of the base. The extension tubes on the two pipes are respectively connected to the through holes on both sides of the cylinder. The outer side of the pipe is fixedly connected to the rotating component through the pipe. The breeding component includes a cylinder with a fixed ring inside. A support ring is located inside the fixed ring, and a groove is formed on the top inner wall of the support ring. Multiple conical cylinders are installed on top of the support rings, with a square plate positioned inside the groove. The fixed ring and a limiting ring are then installed on top of the conical cylinders. After installing the breeding tray, seeds are placed inside the groove. The cylinder is filled with water. The tray containing the seeds is then placed inside the cylinder, submerged in water. Air inside the conical cylinders continuously exchanges with the outside environment through the holes between the support rings, facilitating seed germination. The system provides ample oxygen for seed and root growth, effectively inhibiting the growth of anaerobic microorganisms and reducing the risk of seed and root rot. At the same time, the support structure of the upper and lower double circular plates creates a stable distance between the bottom of the conical cylinder and the water surface, allowing the seeds to be concentrated in the conical cylinder and stably contacted with water. This ensures that all seeds are evenly soaked in water, avoiding germination obstruction caused by drought and preventing seed rot caused by waterlogging and lack of oxygen, thus improving germination uniformity. There are multiple support rings, with a middle plate fixedly connected to the outside of the support ring. The two ends of the middle plate are fixedly connected to two adjacent support rings, and a support component is set inside the support ring. Preferably, the support component includes a conical cylinder with an independent partition design, which can prevent seeds from squeezing and tangling with each other, reduce the risk of cross-infection of diseases and pests, ensure independent growth space for seedling roots, and improve the uniformity of breeding. The outer side of the conical cylinder has an annular groove, and a square plate is fixedly connected to the bottom of the conical cylinder, with the end of the square plate located inside the groove.

[0005] Preferably, there are multiple through grooves evenly distributed on the support rings, and two fixing rings. The multiple support rings are connected radially and annularly by intermediate plates, forming a circular plate. Two trapezoidal grooves are symmetrically arranged on the edge of the cylinder. A through hole is fixedly connected to the inner wall of the cylinder, completely penetrating the cylinder along its diameter. There are multiple support components. Limiting rings are installed inside the fixing rings. The inner diameter of the limiting ring is larger than the top diameter of the conical cylinder. Multiple limiting rings are radially and evenly arranged around a central limiting ring. A fixing plate is fixedly connected to the outer side of the limiting rings, with both ends of the fixing plate... Each of the two adjacent limiting rings is fixedly connected. The multiple limiting rings are connected radially and annularly through fixing plates, forming a circular plate. The upper and lower circular plates form a symmetrical support structure, which allows the tray to be stably placed on the water surface, preventing the conical cylinder from tilting or tipping over, and ensuring that the seeds in all cylinders are submerged at the same depth. The circular groove is located on the fixing plate with the annular connection, and the circular groove connects two adjacent limiting rings. The top of the fixing plate has a circular groove. The limiting ring is located above the support ring. The conical cylinder is located at the interval between the limiting ring and the support ring on the same vertical plane. A semi-circular ring is fixedly connected inside the cylinder. The semi-circular ring is located below the limiting ring. An inclined plate is fixedly connected to the end of the semi-circular ring. There are two inclined plates, and the two inclined plates are fixedly connected to the two ends of the semi-circular ring. There are multiple semicircular rings, divided into two groups, symmetrically arranged. The semicircular rings in each group have different diameters and are distributed in a concentric fan shape. Water enters the cylinder through the through-holes. The inclined plate and the semicircular rings work together to form a narrow guide orifice and annular flow channel. Some water is intercepted by the inclined plate and flows along the circumference of the semicircular ring, while the other part flows along the inclined plate into the interior of the middle semicircular ring, forming a multi-layered annular water flow channel. By setting the inclined plate, water is prevented from passing directly through the middle of the cylinder in a straight line. This forced diversion forces the water to pass through the outer annular flow channel, ensuring that all areas of the cylinder from the center to the edge are covered by water flow. This avoids the problem of water and oxygen deficiency in the outer seeds caused by the shortcut flow of water in the middle.

[0006] Preferably, the top of the conical cylinder is fixedly connected to a limiting ring. There are two annular grooves symmetrically arranged on the conical cylinder. Multiple square plates are evenly distributed on the conical cylinder. A ring plate is fixedly connected to the top of each square plate. The ring plate has smooth edges to prevent scratching damage to seeds and seedling roots, providing a gentle physical environment for root germination and growth. An annular hole is formed at the top of the ring plate, which is located inside the conical cylinder. A spring plate is fixedly connected to the top of the ring plate to install the seed inside the groove. The spring plate forms a flexible restraint on the seeds in the middle from above, preventing the seeds from scattering or being crushed due to water flow fluctuations or tray movement during cultivation. The three intersecting square plates at the bottom form a stable support structure. With the grooves at the joints of the square plates, the seeds can be held from the bottom. Together with the spring plate at the top, they form a fixed effect, keeping the seeds in the optimal cultivation position in the middle of the conical tube, avoiding adhering to the wall and lack of oxygen or drifting and misalignment. There are multiple spring plates, which are evenly distributed on the ring plate. The ring plate is conical, and the joints of the multiple square plates are provided with grooves.

[0007] Preferably, the rotating assembly includes a base, with two side plates fixedly connected to the top edge of the base. The two side plates are symmetrically arranged on the base. A connecting seat is fixedly connected to the top of each side plate. Two connecting rods are provided inside the housing; one connecting rod is fixedly connected to the bottom of the base, and the other is fixedly connected to the top of the connecting seat. The connecting rod located at the bottom of the base is rotatably connected to the inside of the housing. The base and connecting seat are internally hollow cavities. The base is filled with water, and a water pipe is fixedly connected to the outside of the base. After the cylinder is installed, the water pipe... The extension pipe connects to the through hole on the cylinder. When the water pump operates, water from inside the base flows along the water pipes on both sides into the cavity of the connecting seat. It then enters the cylinder through the pipe connected to the connecting seat, passes through the cylinder, and finally returns to the base through the pipe connected to the base on the other side, forming a circulating flow path. This promotes water flow within the cylinder, and the continuous water flow promptly removes carbon dioxide and metabolic waste produced by seed respiration, quickly replenishing the oxygen needed for seed germination. This reduces the risk of seed rot due to oxygen deficiency from the source, and reduces the growth of pathogens and the accumulation of harmful substances in stagnant water environments, creating a clean and breathable environment conducive to seed germination. The water environment reduces the risk of seedling diseases. A water pump is fixedly connected to the middle of the water pipe. There are two water pipes, symmetrically arranged on both sides of the base. The end of the water pipe furthest from the base is fixedly connected to the outside of the connecting seat. Square grooves are evenly distributed on the opposite sides of the side plates. A cylinder is located inside the square groove. A sliding groove is formed in the middle of the square groove, and a retaining plate is slidably connected inside the sliding groove. The cylinder carrying the tray is installed between the two side plates, with both sides of the cylinder inside the square groove, allowing the cylinder to contact the retaining plate and the elastic plate, generating... The compression causes the spring to compress, and the round rod drives the clamping plate to slide inside the groove. When the trapezoidal groove of the cylinder aligns with the groove, the clamping plate is reset under the elastic force of the spring and is located inside the trapezoidal groove. At this time, the cylinder is installed on the rotating assembly through the interlocking cooperation between the clamping plates on both sides and the trapezoidal groove. The clamping plate is located inside the trapezoidal groove. A round rod is fixedly connected to the outside of the clamping plate. The round rod is slidably connected to the side plate. A spring is sleeved on the outside of the round rod. The two ends of the spring are fixedly connected to the clamping plate and the inner wall of the groove, respectively. An elastic plate is fixedly connected to the outside of the clamping plate. The elastic plates are symmetrically arranged at both ends of the clamping plate.

[0008] Preferably, the housing includes a cabinet, with a motor fixedly connected to the top of the cabinet. The output end of the motor is fixedly connected to a connecting rod. An air inlet is provided at the bottom front of the cabinet, and an inner cavity is provided inside the cabinet, so that the air inlet and the air outlet are connected. When the cabinet door is closed, air enters the inner cavity of the cabinet through the air inlet, then enters the interior of the cabinet through the air outlet, and finally exits from the exhaust vent at the top. At the same time, the motor is powered by an external power source and drives the rotating component and the cylinder to rotate through the connecting rod, so that the seeds inside can be evenly exposed to the fixed light lamp, ensuring that all plants receive the same light intensity and duration, avoiding growth differentiation caused by uneven light. The circulating airflow can accelerate the air circulation inside the cabinet, timely replenish the oxygen needed for seed respiration, and remove carbon dioxide, water vapor and metabolic odors. An air outlet is provided at the corner of the cabinet, and an exhaust vent is provided at the top of the cabinet. A light lamp is fixedly connected inside the cabinet.

[0009] A rice hybrid breeding device and method resistant to rice blast includes the following steps: S1. Install the tray; install multiple tapered cylinders on top of multiple support rings so that the square plate is inside the through groove, and then install the limiting ring on top of the tapered cylinders; S2. Place the seed. Install the seed inside the groove. At this time, the elastic plate on the side forms a flexible limit on the seed in the middle from above. S3. Place the tray and install the cylinder with the tray in the middle of the two side plates, so that the clamping plates on both sides and the trapezoidal grooves engage, so that the cylinder is installed on the rotating assembly. S4. Start the circulation. The water pump works, causing the water inside the base to enter the cavity of the connecting seat along the water pipes on both sides. Then, it enters the inside of the cylinder through the pipe connected to the connecting seat, passes through the cylinder, and finally returns to the base through the pipe connected to the base on the other side, forming a circulating flow path. S5. When the device is working, close the cabinet door. Air enters the cabinet through the air inlet and outlet and is finally discharged from the exhaust vent at the top. At the same time, the motor is powered by an external power source. The motor drives the rotating component and the cylinder to rotate through the connecting rod, so that the seeds inside can evenly contact the fixed light lamp.

[0010] This invention provides a device and method for hybrid rice breeding resistant to rice blast. It has the following beneficial effects: (I) The rice hybrid breeding device and method resistant to rice blast, through the support structure of the upper and lower double circular plates, makes the bottom of the conical cylinder and the water surface form a stable distance, which allows the seeds to be concentrated in the conical cylinder and stably contact the water, so that all seeds can be evenly soaked in water, which not only avoids the germination obstruction caused by drought, but also prevents the seed rot caused by water accumulation and lack of oxygen, thus improving the consistency of germination.

[0011] (II) The rice hybrid breeding device and method for resisting rice blast, by setting up an inclined plate, avoids water from passing directly through the middle of the cylinder in a straight line. This forced diversion forces the water to pass through the outer annular flow channel, ensuring that all areas of the cylinder from the center to the edge are covered by water flow, avoiding the problem of water and oxygen deficiency of the seeds on the outside caused by the shortcut flow of water in the middle.

[0012] (III) The rice hybrid breeding device and method resistant to rice blast forms a flexible limit on the seeds in the middle from above through the elastic plate on the side, which prevents the seeds from being scattered or piled up and squeezed due to water flow fluctuations and tray movement during the cultivation process. In addition, the three intersecting square plates at the bottom and the elastic plate at the top form a fixed effect that works together to keep the seeds in the optimal cultivation position in the middle of the conical cylinder, avoiding adhering to the wall and lack of oxygen or drifting and misalignment.

[0013] (iv) The rice hybrid breeding device and method for resisting rice blast uses water flowing inside the cylinder. The continuous water flow can promptly remove carbon dioxide and metabolic waste produced by seed respiration, quickly replenish the oxygen required for seed germination, reduce the risk of seed rot due to lack of oxygen from the root, reduce the growth of pathogens and accumulation of harmful substances in still water environment, create a clean and breathable high-quality water environment for seed germination, and reduce the risk of seedling diseases.

Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0017] First embodiment, such as Figures 1 to 7 As shown, the present invention provides a technical solution: a hybrid rice breeding device and method resistant to rice blast, including a shell 1, a cabinet door 2 hinged to the front end of the shell 1, and a protective cover 6 fixedly connected to the top of the shell 1. Rotating component 3 is rotatably mounted inside housing 1; Breeding component 4 is mounted on rotating component 3. Pipes 5 are fixedly connected to the outside of breeding component 4. There are two pipes 5. Extension pipes are provided on the outside of pipes 5. The extension pipes are connected to through holes 47 on multiple cylinders 41. The top of one pipe 5 is connected to the bottom of connecting seat 33, and the bottom of the other pipe 5 is fixedly connected to the top of connecting seat 33. The two pipes 5 are set on both sides of base 31. The extension pipes on the two pipes 5 are respectively connected to through holes 47 on both sides of cylinder 41. The outside of pipe 5, breeding component 4 is fixedly connected to rotating component 3 through pipe 5. The breeding component 4 includes a cylinder 41, with a fixing ring 43 fixedly connected inside the cylinder 41. A support ring 49 is located inside the fixing ring 43, and a through groove 411 is formed on the top inner wall of the support ring 49. Multiple conical cylinders 461 are installed on top of the multiple support rings 49, such that a square plate 463 is located inside the through groove 411. Then, the fixing ring 43 and a limiting ring 44 are installed on top of the conical cylinder 461. After installing the breeding tray, seeds are placed inside the groove 467. The cylinder 41 is filled with water. The tray containing the seeds is then placed inside the cylinder 41, which is then submerged in water. Air inside the conical cylinder 461 can pass through the holes between the multiple support rings 49. The hole continuously exchanges with the outside world, providing sufficient oxygen for seed germination and root growth, effectively inhibiting the growth of anaerobic microorganisms, and reducing the risk of seed rot and root rot. At the same time, the support structure of the upper and lower double circular plates creates a stable distance between the bottom of the conical cylinder and the water surface, allowing the seeds to be concentrated in the conical cylinder 461 and stably contact the water body. This ensures that all seeds are evenly soaked in water, avoiding germination obstruction caused by drought and preventing seed rot caused by water accumulation and lack of oxygen, thus improving germination uniformity. There are multiple support rings 49, and the outer side of the support ring 49 is fixedly connected to the middle plate 410. The two ends of the middle plate 410 are fixedly connected to two adjacent support rings 49 respectively. The support ring 49 is equipped with a support component 46 inside. The support component 46 includes a conical cylinder 461. The conical cylinder 461 has an independent partition design, which can avoid the seeds from squeezing and tangling with each other, reduce the risk of cross-infection of diseases and pests, ensure the independent growth space of the seedling roots, and improve the uniformity of breeding. The outer side of the conical cylinder 461 is provided with an annular groove 462, and a square plate 463 is fixedly connected to the bottom of the conical cylinder 461. The end of the square plate 463 is located inside the through groove 411.

[0018] There are multiple through grooves 411, which are evenly distributed on the support rings 49. There are two fixing rings 43. The multiple support rings 49 are connected radially and annularly by intermediate plates 410, forming a circular plate. The outer side of the cylinder 41 has two trapezoidal grooves 42, which are symmetrically arranged at the edge of the cylinder 41. The inner wall of the cylinder 41 is fixedly connected with through holes 47, which completely penetrate the cylinder 41 along its diameter. There are multiple support components 46. The fixing rings 43 are provided with limit rings 44 inside. The inner diameter of the limit rings 44 is larger than the top diameter of the conical cylinder 461. There are multiple limit rings 44, which are evenly arranged radially with the central limit ring 44 as the origin. The outer side of the limit rings 44 is fixedly connected with a fixing plate 45, which is divided into two parts. The cone 461 is fixedly connected to two adjacent limiting rings 44. Multiple limiting rings 44 are connected radially and annularly through fixing plates 45, forming a circular plate. The upper and lower circular plates form a symmetrical support structure, which can make the tray stand stably on the water surface and prevent the cone 461 from tilting or tipping over, ensuring that the seeds in all the tubes are at the same depth in the water. The circular groove 48 is located on the annularly connected fixing plate 45. The circular groove 48 connects two adjacent limiting rings 44. The top of the fixing plate 45 has a circular groove 48. The limiting ring 44 is located above the support ring 49. The cone 461 is located at the interval between the limiting ring 44 and the support ring 49 on the same vertical plane. A semi-circular ring 413 is fixedly connected inside the cylinder 41. The semi-circular ring 413 is located below the limiting ring 44. An inclined plate 412 is fixedly connected to the end of the semi-circular ring 413. There are two inclined plates 412. The two inclined plates 412 are fixedly connected to the two ends of the semi-circular ring 413. There are multiple semicircular rings 413, which are divided into two groups. The two groups of semicircular rings 413 are symmetrically arranged. The diameters of the multiple semicircular rings 413 in one group are different. The multiple semicircular rings 413 in one group are distributed in a concentric fan shape. Water enters the inside of the cylinder 41 through the through hole 47. The inclined plate 412 cooperates with the semicircular rings 413 to form a path design of narrow guide orifice and annular flow channel. After being intercepted by the inclined plate 412, part of the water flows along the circumference of the semicircular rings 413, while the other part of the water flows along the inclined plate 412 into the inside of the middle semicircular rings 413, forming a multi-layered annular water flow channel. By setting the inclined plate 412, water is prevented from passing directly through the middle of the cylinder 41 in a straight line. This forced diversion forces the water to pass through the outer annular flow channel, ensuring that all areas of the cylinder 41 from the center to the edge are covered by water flow, avoiding the problem of water and oxygen deficiency of the seeds on the outside caused by the shortcut flow of water in the middle.

[0019] The second embodiment is based on the first embodiment; please refer to [link / reference]. Figure 8As shown, the top of the conical cylinder 461 is fixedly connected to the limiting ring 44. There are two annular grooves 462, which are symmetrically arranged on the conical cylinder 461. There are multiple square plates 463, which are evenly distributed on the conical cylinder 461. A ring plate 465 is fixedly connected to the top of the square plate 463. The edge of the ring plate 465 is smooth, which can prevent the corners of the square plate 463 from scratching and damaging the seeds and seedling roots, and provide a mild physical environment for root germination and growth. An annular hole 466 is opened at the top of the ring plate 465. The ring plate 465 is located inside the conical cylinder 461. A spring plate 464 is fixedly connected to the top of the ring plate 465 to install the seeds in the concave hole. Inside the trough 467, the side spring plates 464 provide flexible support for the seeds in the center from above, preventing them from scattering or being crushed due to water flow fluctuations or tray movement during cultivation. The three intersecting square plates 463 at the bottom form a stable support structure. Together with the grooves 467 at the connection points of the square plates, they can hold the seeds from the bottom, forming a fixed effect with the top spring plates. This ensures that the seeds are always in the optimal cultivation position in the center of the conical cylinder 461, avoiding adhering to the wall and lack of oxygen or drifting and misalignment. There are multiple spring plates 464, which are evenly distributed on the ring plate 465. The ring plate 465 is conical, and the connection points of the multiple square plates 463 are provided with grooves 467.

[0020] The third embodiment is based on embodiments one and two; please refer to [link / reference]. Figures 9 to 12As shown, the rotating assembly 3 includes a base 31, with two side plates 32 fixedly connected to the top edge of the base 31. The two side plates 32 are symmetrically arranged on the base 31. A connecting seat 33 is fixedly connected to the top of the side plates 32. Two connecting rods 34 are provided inside the housing 1. One connecting rod 34 is fixedly connected to the bottom of the base 31, and the other connecting rod 34 is fixedly connected to the top of the connecting seat 33. The connecting rod 34 located at the bottom of the base 31 is rotatably connected to the interior of the housing 1. The interiors of the base 31 and the connecting seat 33 are hollow cavities. The interior of the base 31 is filled with water, and a water pipe 35 is fixedly connected to the outside of the base 31. After the cylinder 41 is installed, the extension of the pipe 5... The long pipe connects to the through hole 47 on the cylinder 41. When the water pump 36 operates, water inside the base 31 flows along the water pipes 35 on both sides into the cavity of the connecting seat 33. Then, it enters the interior of the cylinder 41 through the pipe 5 connected to the connecting seat 33, passes through the cylinder 41, and finally returns to the base 31 through the pipe 5 connected to the base 31 on the other side, forming a circulating flow path. This promotes the flow of water outside the cylinder 41. The continuous water flow can promptly remove carbon dioxide and metabolic waste produced by seed respiration, quickly replenishing the oxygen needed for seed germination. This reduces the risk of seed rot due to oxygen deficiency from the root, reduces the growth of pathogens and the accumulation of harmful substances in stagnant water environments, creates a clean and breathable high-quality water environment for seed germination, and reduces the risk of seedling diseases. The middle part of the water pipe 35 is fixed. A water pump 36 is fixedly connected to the base 31. There are two water pipes 35, symmetrically arranged on both sides of the base 31. The end of each water pipe 35 away from the base 31 is fixedly connected to the outer side of the connecting seat 33. Multiple square grooves 37 are evenly distributed on the opposite sides of the side plates 32. A cylinder 41 is located inside the square groove 37. A sliding groove 38 is formed in the middle of the square groove 37. A retaining plate 39 is slidably connected inside the sliding groove 38. The cylinder 41, carrying a tray, is installed in the middle of the two side plates 32, with both sides of the cylinder 41 inside the square groove 37. This causes the cylinder 41 to contact and compress with the retaining plate 39 and the elastic plate 312, thereby compressing the spring 311. Rod 310 drives the clamping plate 39 to slide inside the slide groove 38. When the trapezoidal groove 42 of the cylinder 41 aligns with the slide groove 38, the clamping plate 39 is reset under the elastic force of the spring 311 and is located inside the trapezoidal groove 42. At this time, through the snap-fit ​​between the clamping plates 39 on both sides and the trapezoidal groove 42, the cylinder 41 is mounted on the rotating assembly 3, and the clamping plate 39 is located inside the trapezoidal groove 42. A round rod 310 is fixedly connected to the outside of the clamping plate 39. The round rod 310 is slidably connected to the side plate 32. A spring 311 is sleeved on the outside of the round rod 310. The two ends of the spring 311 are fixedly connected to the inner walls of the clamping plate 39 and the slide groove 38, respectively. An elastic plate 312 is fixedly connected to the outside of the clamping plate 39. The elastic plates 312 are symmetrically arranged at both ends of the clamping plate 39.

[0021] The housing 1 includes a cabinet 11. A motor 16 is fixedly connected to the top of the cabinet 11. The output end of the motor 16 is fixedly connected to a connecting rod 34. An air inlet 12 is provided at the bottom front of the cabinet 11. An inner cavity is provided inside the cabinet 11, so that the air inlet 12 and the air outlet 13 are in a connected state. When the cabinet door 2 is closed, air enters the inner cavity of the cabinet 11 through the air inlet 12, then enters the interior of the cabinet 11 through the air outlet 13, and finally exits from the exhaust vent 15 at the top. At the same time, the motor 16 is powered by an external power source. The motor 16 is connected to a connecting rod 34. The rod 34 drives the rotating component 3 and the cylinder 41 to rotate, so that the seeds inside can evenly contact the fixed light lamp, ensuring that all plants receive the same light intensity and duration, avoiding growth differentiation caused by uneven light. The circulating air can accelerate the air circulation inside the cabinet 11, timely replenishing the oxygen needed for seed respiration, while removing carbon dioxide, water vapor and metabolic odors. An air outlet 13 is opened at the corner of the cabinet 11, and an exhaust vent 15 is opened at the top of the cabinet 11. A light lamp 14 is fixedly connected inside the cabinet 11.

Install the tray; install multiple conical cylinders 461 on top of multiple support rings 49, so that the square plate 463 is located inside the through groove 411, and then install the limiting ring 44 on top of the conical cylinders 461. S2. Place the seed and install it inside the groove 467. At this time, the side spring plate 464 forms a flexible limit on the seed in the middle from above. S3. Place the tray and install the cylinder 41 with the tray in the middle of the two side plates 32, so that the clamping plates 39 on both sides and the trapezoidal groove 42 are engaged, so that the cylinder 41 is installed on the rotating assembly 3. S4. Start the circulation. The water pump 36 works, so that the water inside the base 31 enters the cavity of the connecting seat 33 along the water pipes 35 on both sides, and then enters the inside of the cylinder 41 through the pipe 5 connected to the connecting seat 33, passes through the cylinder 41, and finally returns to the base 31 through the pipe 5 connected to the base 31 on the other side, forming a circulation path. S5. When the device is working, close the cabinet door 2. Air enters the interior of the cabinet 11 through the air inlet 12 and the air outlet 13, and finally exits from the exhaust vent 15 at the top. At the same time, the motor 16 drives the rotating component 3 and the cylinder 41 to rotate through the connecting rod 34, so that the seeds inside can evenly contact the fixed light lamp.

[0023] In use, multiple conical cylinders 461 are installed on top of multiple support rings 49, so that the square plate 463 is located inside the through groove 411. Then, the fixing ring 43 and the limiting ring 44 are installed on top of the conical cylinder 461. After the breeding tray is installed, the seeds are placed inside the groove 467. The inside of the cylinder 41 is filled with water. Then, the tray with seeds is placed inside the cylinder 41, at which time the tray is placed in the water.

[0024] The cylinder 41 with the tray is installed in the middle of the two side plates 32, and the two sides of the cylinder 41 are located inside the square groove 37, so that the cylinder 41 contacts the clamping plate 39 and the elastic plate 312 and generates compression, thereby compressing the spring 311. The round rod 310 drives the clamping plate 39 to slide inside the slide groove 38. When the trapezoidal groove 42 of the cylinder 41 is aligned with the slide groove 38, the clamping plate 39 is reset under the elastic force of the spring 311 and is located inside the trapezoidal groove 42. At this time, the cylinder 41 is installed on the rotating assembly 3 through the snap-fit ​​between the clamping plates 39 on both sides and the trapezoidal groove 42.

[0025] After the cylinder 41 is installed, the extension pipe on the pipe 5 is connected to the through hole 47 on the cylinder 41. The water pump 36 is activated, causing the water inside the base 31 to enter the cavity of the connecting seat 33 along the water pipes 35 on both sides. Then, it enters the interior of the cylinder 41 through the pipe 5 connected to the connecting seat 33, passes through the cylinder 41, and finally returns to the base 31 through the pipe 5 connected to the base 31 on the other side, forming a circulating flow path.

[0026] When the cabinet door 2 is closed, air enters the inner cavity of the cabinet 11 through the air inlet 12, then enters the interior of the cabinet 11 through the air outlet 13, and finally exits through the exhaust vent 15 at the top. At the same time, the motor 16 is powered by an external power source. The motor 16 drives the rotating component 3 and the cylinder 41 to rotate through the connecting rod 34, so that the seeds inside can evenly contact the fixed light lamp.
