Description

Technical Field

[0001] This invention relates to the field of rice breeding equipment, specifically to an intelligent rice germination device. Background Technology

[0002] Rice germination is a core pre-process in rice seedling cultivation and planting. The uniformity of germination and the emergence rate directly determine the subsequent seedling growth, transplanting quality, and final rice yield. Rice germination is divided into several stages: soaking seeds for water absorption, high-temperature seed breaking, uniform germination at suitable temperature, and low-temperature hardening. Among these, the high-temperature seed breaking stage is the critical period affecting the success rate of germination.

[0003] In practical applications, existing intelligent germination boxes (such as the LD-330 seed germination box) mainly germinate rice by balancing the temperature of the air inside the box and circulating ventilation. However, they are unable to effectively dissipate the self-generated heat accumulated inside the seed pile after the seeds are stacked. Even when seeds are laid flat and layered, during the high-temperature, high-heat-generating stage, heat still accumulates in the seed core, and the local temperature exceeds the suitable germination temperature, making it difficult to effectively dissipate the self-generated heat accumulated inside the seed pile. To reduce the risk of heat buildup and scorching of the seedlings, operators usually need to open the box door at fixed intervals to turn the seeds. However, opening the box door easily disrupts the constant temperature and humidity environment inside the box, damaging the stable conditions required for germination.

[0004] Therefore, the present invention provides an intelligent rice germination device to solve the above problems. Summary of the Invention

[0005] To address the aforementioned issues, this invention provides an intelligent rice germination device that intelligently completes seed turning and heat dissipation while balancing the air temperature within the container, reducing heat dissipation during manual opening of the container and improving rice germination quality and seedling uniformity.

[0006] To achieve the above objectives, the technical solution of the present invention is as follows: A smart rice germination device includes a constant temperature chamber, a controller, several placement seats, and several germination trays. The constant temperature chamber has several lifting seats fixedly connected to its inner wall, each corresponding to one of the placement seats. Each lifting seat has a lifting assembly fixedly connected to its bottom end. The output end of each lifting assembly is rotatably connected to a turning assembly for stirring the rice in the germination trays. The lifting assembly is used to adjust the distance between the turning assembly and the corresponding bottom wall of the germination tray. Both the lifting assembly and the turning assembly are electrically connected to the controller.

[0007] Furthermore, each lifting component includes several first electrically controlled telescopic columns and several second electrically controlled telescopic columns, and both the first and second electrically controlled telescopic columns are electrically connected to the controller.

[0008] On each lifting seat, the first electrically controlled telescopic columns are linearly arrayed along the width direction of the lifting seat and are defined as the first adjustment group; the second electrically controlled telescopic columns are linearly arrayed along the width direction of the lifting seat and are defined as the second adjustment group; the first adjustment group and the second adjustment group are symmetrically distributed on both sides of the corresponding lifting seat width direction.

[0009] Furthermore, each of the turning components includes a tumbling prism; the output end of each of the first electrically controlled telescopic columns is fixedly connected to a drive seat, and the drive seat is equipped with a motor electrically connected to the controller; the output end of each of the second electrically controlled telescopic columns is fixedly connected to a driven seat; one end of each tumbling prism is rotatably connected to the driven seat, and the other end of each tumbling prism is coaxially fixedly connected to the output end of the motor inside the drive seat, and the tumbling prism and the drive seat are rotatably engaged.

[0010] When the tumbling prism is at a stop, the plane containing the two opposite edges of the tumbling prism is always perpendicular to the bottom surface of the germination tray.

[0011] Furthermore, all the tumbling prisms are tetragonal prism structures.

[0012] Furthermore, all the tumbling prisms are hollow structures and are defined as transition cavities; the surface of each tumbling prism has several vent holes that communicate with the transition cavities.

[0013] Furthermore, each edge of the tumbling prism has several through holes that communicate with the transition cavity.

[0014] Furthermore, the inverted triangular area formed between two adjacent tumbling prisms is defined as the flow guiding zone; each germination tray is equipped with a flow guiding component at its top to guide the ventilation airflow along the length of the flow guiding zone; the flow guiding components are all electrically connected to the controller.

[0015] Furthermore, each of the flow guiding components includes several first flow guiding grooves and several second flow guiding grooves opened on the surface of the germination tray; each flow guiding area is connected to the first flow guiding groove and the second flow guiding groove at both ends respectively; each of the first flow guiding grooves is connected to an auxiliary air inlet channel disposed inside the constant temperature chamber, and each of the auxiliary air inlet channels is equipped with an auxiliary fan electrically connected to the controller; each of the second flow guiding grooves is connected to an auxiliary air return channel disposed inside the constant temperature chamber.

[0016] Furthermore, several temperature sensors electrically connected to the controller are fixedly connected to each edge of the transition cavity.

[0017] Furthermore, both the germination tray and the inner bottom edge along the length direction have rounded corners.

[0018] The above approach has the following beneficial effects:

[0019] 1. This solution uses a controller to intelligently and automatically turn and dissipate heat from the rice seeds on the germination tray. The motor drives the tumbling prism to rotate, and the edges of the prism are inserted into the rice seed layer in the germination tray. The continuous rotation completes the automated turning and heat dissipation operation, which can dissipate the heat accumulated inside the rice seed core in time, reduce the occurrence of scorching and suffocation of rice seeds during the high-temperature germination stage. At the same time, it eliminates the need for manual periodic opening and turning of the box for heat dissipation in existing technologies, reduces the disruption of the constant temperature and humidity environment inside the box by opening the box door, and prevents the intrusion of cold air and impurities from damaging the stable working conditions required for germination. It ensures that the cultivation environment inside the box always meets the standards, which reduces the intensity of manual labor and maintains high-quality germination conditions throughout the process.

[0020] 2. This solution can also be used during the early seed placement stage of germination. The rolling prism is directly inserted into the flat-laid rice seeds, dividing the entire tray of seeds into multiple trapezoidal areas, ensuring the outer wall of the rolling prism fully adheres to the inner layer of the seeds. The hollow transition cavity inside the rolling prism, along with the ventilation holes and perforations on the outer wall and edges, forms a continuous airflow channel. This allows the air circulating within the constant temperature chamber to be directly guided and transported to the deepest part of the rice seeds, increasing the contact area between the seed layer and the air, improving the air circulation efficiency within the rice seed pile, accelerating heat dissipation, further optimizing the overall ventilation and heat dissipation conditions of the seeds, and ensuring a more uniform temperature environment between the upper and lower layers of seeds.

[0021] 3. This solution uses a temperature sensor inside the transition cavity to accurately collect real-time temperature data of the rice seed pile and feed it back to the controller. The controller flexibly adjusts the operating power of the auxiliary fan based on the measured temperature, regulating the airflow velocity and volume delivered into the guide zone through the auxiliary air intake channel. The airflow flows directionally along the guide zone and remains parallel to the surface of the tumbling prism. Based on Bernoulli's principle, a stable negative pressure environment is created inside the hollow transition cavity, which in turn guides the gas inside the transition cavity to flow upwards towards the prism, quickly drawing in and expelling the heat accumulated deep within the seeds.

[0022] Additional aspects and advantages of the invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0034] The following detailed description illustrates the specific implementation method:

[0035] Example 1:

[0036] like Figure 1 As shown, an intelligent rice germination device includes a constant temperature chamber 1, a controller, and several germination trays 4. Several linear arrays (such as...) are screwed into the constant temperature chamber 1. Figure 1 As shown, the placement seat 101 is located along the height of the constant temperature chamber 1. The heating and humidification structure of the constant temperature chamber 1 is based on existing equipment designs (such as the LD-330 seed germination box), and will not be described in detail here.

[0037] In particular, combined Figure 2 As shown, the inner wall of the constant temperature chamber 1 is screwed with several lifting seats 2 corresponding one-to-one with the placement seats 101. Each lifting seat 2 has several first electrically controlled telescopic columns 3 and several second electrically controlled telescopic columns screwed to its bottom end. Both the first and second electrically controlled telescopic columns are electrically connected to a controller. Furthermore, on each lifting seat 2, the first electrically controlled telescopic columns 3 are linearly arrayed along the width direction of the lifting seat 2 and defined as a first adjustment group; the second electrically controlled telescopic columns are also linearly arrayed along the width direction of the lifting seat 2 and defined as a second adjustment group. The first and second adjustment groups are symmetrically distributed on both sides of the corresponding lifting seat 2 in the width direction.

[0038] like Figure 3 As shown, the output ends of the first electrically controlled telescopic column 3 are all welded with drive seats 301, and each drive seat 301 contains a motor electrically connected to the controller; the output ends of the second electrically controlled telescopic column are all welded with driven seats. Figure 4 As shown, the output shaft of the motor is coaxially bolted to a rolling prism 5 that rotatably engages with the drive seat 301. Each rolling prism 5 is a quadrangular prism structure, hollow in shape, and defined as a transition cavity. Several vent holes communicating with the transition cavity are opened on the surface of each rolling prism 5, and several through holes communicating with the transition cavity are opened at the edges of each rolling prism 5. One end of each rolling prism 5 is rotatably connected to the corresponding driven seat. Furthermore, when the rolling prism 5 is in a stopped state, the plane containing the two opposite edges of the rolling prism 5 is always perpendicular to the bottom surface of the germination tray 4. The inner bottom edge of the germination tray 4 along its length is rounded. Figure 5 As shown, several temperature sensors 6, which are electrically connected to the controller, are bonded to each edge of the transition cavity.

[0039] The specific implementation process is as follows: After placing the rice seed germination tray 4, which has been laid flat, on the corresponding placement seat 101, the constant temperature chamber 1 first stabilizes the internal temperature and humidity to maintain the standard environment required for rice germination, and then enters the fully automatic intelligent germination process as follows:

[0040] First, the controller controls the first and second electrically controlled telescopic columns to extend downwards synchronously, driving the drive seat 301, driven seat, and tumbling prism 5 to move smoothly downwards as a whole. The vertical quadrangular prism edges are inserted at a uniform speed into the flat rice seed layer. The downward depth is adjusted according to the seed layer thickness, so that the bottom of the tumbling prism 5 is close to the bottom of the germination tray 4, evenly dividing the continuously flat rice seeds into multiple independent trapezoidal heat dissipation areas. The transition cavity inside the tumbling prism 5 serves as the main ventilation channel, and together with the densely distributed air vents on the column body and the through holes on the edges, a three-dimensional air guiding structure is formed that connects the inside and outside. This allows the stable temperature and humidity airflow in the constant temperature chamber 1 to be introduced from the surface to the middle and bottom layers of the seeds and the sealed area of ​​the core. In addition, since the corners of the germination tray 4 are prone to seed accumulation dead corners and poor heat dissipation, an initial pre-treatment process is added after the partitioning is completed: the controller controls the rotation of the outermost tumbling prism 5 separately, and orderly pushes the seeds accumulated in the rounded corner area of ​​the germination tray 4 into the adjacent regular trapezoidal heat dissipation area, clearing the edge seed accumulation blind area, and ensuring that all seeds are in the standardized heat dissipation area as much as possible; the two outermost tumbling prisms 5 are not included in the subsequent pile turning process.

[0041] During the germination process, multiple temperature sensors 6 within the transition chamber continuously collect real-time temperature data from the inside of the rice seeds and feed it back to the controller for data comparison and analysis. The controller focuses on monitoring the intense heat release during the high-temperature seed-breaking stage to detect localized abnormal heat accumulation and overheating. The controller has a preset dual-trigger logic for turning the seed pile: 1. Timed Turning Mode: The controller automatically starts the turning program at preset intervals, with all turning prisms 5 rotating synchronously and in the same direction, achieving a neat and orderly overall turning operation; 2. Temperature Trigger Mode: When the seed pile core temperature exceeds a preset safety threshold, resulting in localized heat accumulation and temperature rise, an emergency turning mechanism is triggered. The turning prisms 5 on both sides of the corresponding overheated trapezoidal heat dissipation area are selected for rotation, specifically agitating and dissipating heat from the seeds in the localized heat accumulation area, achieving precise cooling at designated points.

[0042] After triggering the turning process, the controller starts the internal motor of the drive unit 301, driving the tumbling prism 5 to rotate at a constant speed. The edges of the tumbling prism 5 continuously agitate the seed layer, breaking up the compacted seeds and dissipating the self-generated heat accumulated in the core. Furthermore, during each turning process, a forward and reverse rotation strategy is implemented to ensure that the number of forward and reverse rotations is completely consistent. Through bidirectional symmetrical agitation, the positions of the upper and lower layers and inner and outer layers of seeds are smoothly exchanged while breaking up the compacted seed layer, reducing the situation of seed displacement and uneven agitation caused by unidirectional turning. In addition, after each turning operation, when the motor stops, all tumbling prisms 5 automatically reset and calibrate, so that the edges of the tumbling prism 5 are once again vertically aligned with the bottom of the germination tray 4, and a regular trapezoidal independent heat dissipation area is formed again, providing a stable structural foundation for the next stage of static zoned heat dissipation operation.

[0043] Example 2:

[0044] The difference from Example 1 is that, as Figure 4 and Figure 7 As shown, the inverted triangular area formed between two adjacent tumbling prisms 5 is defined as the flow guiding area (above the rice seed layer); each germination tray 4 is provided with a flow guiding component at its top for guiding the ventilation airflow along the length of the flow guiding area; each flow guiding component is electrically connected to the controller. Specifically, each flow guiding component includes several first flow guiding grooves 401 and several second flow guiding grooves opened on the surface of the germination tray 4; each flow guiding area is connected to the first flow guiding groove 401 and the second flow guiding groove at both ends respectively; each first flow guiding groove 401 is connected to an auxiliary air inlet channel 7 located inside the constant temperature chamber 1, and each auxiliary air inlet channel 7 is provided with an auxiliary fan electrically connected to the controller; each second flow guiding groove is connected to an auxiliary air return channel located inside the constant temperature chamber 1.

[0045] The specific implementation process is as follows: During the conventional static zoned heat dissipation stage, the controller dynamically adjusts the start / stop status and output power of each auxiliary fan based on the real-time temperature data of the seed pile collected by the temperature sensor 6 inside the tumbling prism 5. After the auxiliary fans start, the stable warm and humid airflow inside the constant temperature chamber 1 is uniformly introduced into the first guide channel 401 through the auxiliary air inlet channel 7. The airflow is limited and guided by the first guide channel 401, strictly flowing through the length direction of the guide area, smoothly passing over the outer upper surface of the tumbling prism 5, and finally flowing into the auxiliary return air channel through the second guide channel, forming a continuous, regular, and directional closed-loop airflow circulation.

[0046] As the airflow flows at high speed parallel along the guide zone, a stable negative pressure environment is formed inside the transition cavity of the tumbling prism 5 based on Bernoulli's principle. The high-temperature and humid gas accumulated in the seed core and bottom layer can be continuously drawn in through the vent holes and edge through holes on the lower outer surface of the tumbling prism 5, so that the internal humid airflow quickly merges into the transition cavity and is discharged with the external guide airflow. During the high-temperature, high-heat-generating stage of the brain or when the device triggers the timed, overheated turning mechanism, a time-sharing operation logic of "turning first, then ventilation" is adopted. Priority is given to completing the bidirectional forward and reverse turning operation. The seed accumulation layer is broken up by stirring the rolling prism 5, so that the high-temperature heat accumulated in the core can be fully dissipated, exposing it to the gaps between the seed layers. After the turning operation is completely completed, the rolling prism 5 is reset to a vertical static state and a trapezoidal flow guide zone is re-formed, and then the auxiliary fan is started and the operating speed is increased to increase the airflow in the flow guide zone. The directional high-speed airflow is used to quickly remove the large amount of residual heat and moisture released after turning, improve the efficiency of deep heat discharge, and reduce the risk of seed damage and bud stunting caused by local high temperature accumulation.

[0047] Meanwhile, during the temperature-triggered local turning and stirring process, only the tumbling prisms 5 on both sides of the overheated flow guide zone participate in the rotation operation. During the forward (or reverse) rotation, the seeds in this heat dissipation zone will be pushed and piled up in an orderly manner to the upper surface of the adjacent tumbling prism 5 that has not yet started operation. During the subsequent reverse (or forward) reset process, the plump, compact, and high-quality seeds will slide naturally from the prism surface and fall back into the heat dissipation zone due to gravity. However, the extremely light empty shell seeds and shriveled and unplump seeds are not able to overcome the adhesion resistance of the contact surface due to their own weight, and are difficult to slide down with gravity. They will eventually remain stably on the upper surface of the adjacent tumbling prism 5 that has not yet started operation, thus realizing the automatic stratification and fixed-point retention of superior and inferior seeds. After the turning operation is completely completed and all the tumbling prisms 5 are reset to a vertical static state, forming a regular trapezoidal airflow channel, the auxiliary fan is started to generate gas that flows stably and at high speed along the airflow channel. This gas acts on the upper surface of the tumbling prisms 5 and the empty shells, shriveled and unripe seeds retained in the airflow channel. Using the thrust of a stable directional airflow, the scattered and retained inferior seeds are blown and gathered in the end area away from the first airflow channel 401, realizing the centralized sorting and differentiation of inferior seeds. This makes it easier for staff to quickly clean up inferior seeds and count the number of effective seeds and the actual germination rate.

[0048] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
