[0002] In traditional agricultural production and seed processing, accurate assessment of seed fluidity, particle size distribution and degree of dryness is the key to ensuring seed quality, storage stability and sowing effect. However, existing detection technologies and equipment often have many limitations, such as single detection means, poor adaptability, insufficient precision and other problems, which can hardly meet the needs of modern agricultural production for comprehensive and efficient detection of seed quality. Specifically, traditional methods usually rely on manual screening or use single-function detection instruments to separately evaluate the particle size, fluidity and dryness of seeds, which is not only time-consuming and labor-intensive, but also difficult to ensure the accuracy and consistency of the test results. In addition, different types of seeds have significant differences in shape, size and physical properties. There is a lack of a comprehensive detection device that can flexibly adapt to different seed characteristics, which greatly reduces the detection efficiency and accuracy. Summary of the invention

[0020] like Figure 1-4As shown, the present embodiment provides an adaptable and adjustable seed fluidity detector, including a particle size detection slot 2, the inner bottom of which is provided with a plurality of strip openings 201, the width of each strip opening 201 increases or decreases from one side to the other, and the width data of each strip opening 201 is marked. By designing a particle size detection slot 2 with strip openings 201 of different widths, seeds of different particle sizes can be accurately distinguished, and the width data of each strip opening 201 is marked, which is convenient for direct reading and recording, greatly improving the accuracy and efficiency of particle size detection. At the same time, the width of the strip opening 201 of the particle size detection slot 2 can be increased or decreased, and the adjustability of the flowability detection plate 1 makes the present invention applicable to seeds of various shapes and sizes, greatly enhancing the versatility and adaptability of the equipment. Whether in scientific research experiments or actual production, the most suitable detection configuration can be found; The flowability detection plate 1 is hinged on one side of the particle size detection tank 2. The hinged design of the flowability detection plate 1 makes the detection process more flexible and can meet the flow characteristic test requirements of different seeds; The dryness detection slot 3 is arranged directly below the particle size detection slot 2. A plurality of drying slots 301 are provided on the dryness detection slot 3. The positions of the drying slots 301 and the strip-shaped openings 201 correspond to each other in the vertical direction. The corresponding drying slots 301 and the strip-shaped openings 201 have the same size specifications. A heating resistor 303 is provided in the dryness detection slot 3. The heating resistor 303 is used to increase the temperature in each drying slot 301. The electronic scale 4 is supported and arranged at the bottom of the dryness detection tank 3. The electronic scale 4 is used to weigh the weight change of the dryness detection tank 3 before and after drying. The introduction of the electronic scale 4 not only realizes the accurate measurement of the weight change before and after the dryness detection, but also provides the possibility for automatic data recording and analysis, which is helpful to build a database of seed quality and provide a basis for subsequent agricultural production decisions. The control of the heating resistor 303 also makes the drying process more controllable, ensuring the accuracy and repeatability of the dryness detection.
[0021] The present invention integrates three functions of particle size detection, fluidity detection and dryness detection into one, avoiding the tediousness of the traditional method that requires multiple devices to detect separately, significantly improving the detection efficiency and reducing the cost. In particular, the corresponding design of the dryness detection slot 3 and the particle size detection slot 2 ensures that the same batch of seeds can be directly tested for dryness after the particle size detection, ensuring the consistency and reliability of the detection data.
[0022] The working principle of the adaptable and adjustable seed fluidity detector of the present invention is as follows: First, the flow state of seeds during actual storage, transportation or sowing is simulated by adjusting the angle of the flowability test board 1, and the flowability of the seeds is observed and recorded. The hinged design of the flowability test board 1 enables it to be flexibly adjusted according to the characteristics of the seeds to ensure the accuracy of the test results.
[0023] Then, the seeds roll down along the flowability detection plate 1 into the particle size detection slot 2, and the seeds fall into the strip openings 201 of different widths according to their own particle sizes. Since the width of the strip openings 201 increases or decreases from one side to the other, and the width data of each strip opening 201 is marked, the particle size distribution of the seeds can be intuitively judged and recorded. This design utilizes the principle of physical screening to achieve rapid and accurate classification of seed particle sizes.
[0024] Subsequently, the seeds fall into the dryness detection slot 3 below through the strip-shaped opening 201. The corresponding drying slot 301 is consistent with the strip-shaped opening 201 in size, ensuring that seeds of each particle size can be accurately tested for dryness. After the heating resistor 303 is started, the temperature in the drying slot 301 will be evenly increased to accelerate the drying process of the seeds. By accurately weighing the weight change before and after drying by the electronic scale 4, the water content of the seeds can be calculated, and then the degree of dryness can be evaluated. This process not only realizes the quantitative analysis of seed dryness, but also provides a scientific basis for subsequent moisture management.
[0025] In summary, the adaptable and adjustable seed fluidity detector of the present invention realizes comprehensive, efficient and accurate detection of seed particle size, fluidity and dryness through ingenious mechanical structure and intelligent design, providing strong technical support for seed quality control in agricultural production.
[0026] In some embodiments, the flowability test plate 1 is hinged to one side of the particle size detection tank 2 by a damping hinge structure, and the damping hinge structure includes a damper and a hinge assembly, wherein the damper provides resistance to the flowability test plate 1 when adjusting the angle, so that the flowability test plate 1 can remain stable at any set angle and will not change its position at will due to a slight touch of an external force. The hinge assembly ensures that the flowability test plate 1 can rotate smoothly around one side of the particle size detection tank 2. The damping hinge design enables the flowability test plate 1 to remain firmly in position after being adjusted to a specific angle, and will not easily change the angle even if it is subjected to the impact force of the seed or slight external vibration during the detection process. This ensures the continuity and accuracy of the flowability test, because a slight change in the angle may affect the flow behavior of the seed, thereby affecting the test results. And the presence of the damper enables the operator to feel moderate resistance when adjusting the angle of the flowability test plate 1, which is neither too laborious nor too fast. It can avoid angle setting errors or equipment damage caused by too fast operation. This design improves the convenience and safety of operation and reduces the risk of human error.
[0027] In some embodiments, the damping hinge structure also includes an angle detection mechanism, which is connected to the flowability detection plate 1, and is used to detect and display the current angle value of the flowability detection plate 1 in real time, and to detect the natural repose angle of the seeds accumulated on the flowability detection plate 1. The angle detection mechanism may include a high-precision angle sensor and a data processing unit. The high-precision angle sensor is directly installed at the hinge of the flowability detection plate 1, and is used to accurately measure the inclination angle of the detection plate, and transmit the angle data to the data processing unit in real time; the data processing unit calculates the natural repose angle of the seeds according to the received angle data and a preset algorithm model, and judges the flowability of the seeds accordingly. The smaller the repose angle, the stronger the flowability of the seeds. Through the accurate measurement of the natural repose angle by the angle detection mechanism, the present invention can realize the quantitative evaluation of the flowability of the seeds. Traditionally, the flowability of seeds often depends on the subjective judgment of the operator and lacks objective basis. The present invention provides a specific numerical indicator for the flowability of seeds by measuring the repose angle, so that the evaluation result is more accurate and reliable.
[0028] In some embodiments, Figure 2As shown, a vibration motor 202 is provided on the particle size detection slot 2, and the vibration motor 202 is connected to the side wall or the bottom of the particle size detection slot 2, and is used to provide controllable vibration to the particle size detection slot 2 during the detection process. The introduction of the vibration motor 202 enables the seeds accumulated near the strip-shaped opening 201 to be uniformly and appropriately vibrated, thereby effectively avoiding the seeds from blocking the strip-shaped opening 201 due to factors such as static electricity, friction or accumulation morphology, ensuring that the seeds can smoothly fall into the corresponding strip-shaped opening 201, and improving the accuracy and reliability of particle size detection. The setting of the vibration motor 202 breaks the accumulation state of the seeds near the strip-shaped opening 201 through the vibration action, and reduces the detection error caused by the mutual adhesion between seeds or the irregular accumulation morphology. This allows seeds of each particle size to fall into the corresponding strip-shaped opening 201 more accurately, improving the accuracy and resolution of particle size detection. In addition, for some seeds with special shapes, rough surfaces or prone to static electricity, traditional static particle size detection methods may be difficult to accurately classify. The introduction of the vibration motor 202 effectively solves these problems through vibration, making the present invention applicable to a wider range of seed types and enhancing the versatility and adaptability of the device.
[0029] In some embodiments, Figure 3 As shown, a trumpet-shaped enclosure 302 is provided on the top of the dryness detection slot 3. The enclosure 302 fits tightly to the edge of the dryness detection slot 3 and extends upward to a certain height, forming a trumpet-shaped structure that gradually expands outward. The main purpose of the design of this enclosure 302 is to prevent the seeds from splashing outside the dryness detection slot 3 in the process of falling from the strip-shaped opening 201 into the corresponding drying slot 301, and to ensure that all seeds can accurately fall into the designated drying slot 301. This provides an effective guiding and restraining effect for the seeds. When the seeds fall from the strip-shaped opening 201, even if there is a certain initial velocity or jump, they will be guided by the enclosure 302 and fall into the corresponding drying slot 301, effectively preventing the splashing and loss of seeds, and ensuring the integrity and accuracy of the test samples.
[0030] In some embodiments, Figure 4 As shown, the heating resistor 303 is distributed in each drying slot 301 and embedded in the inner wall of the drying slot 301. This design enables the heating resistor 303 to directly and evenly heat the seeds in the drying slot 301, ensuring that the temperature distribution in each drying slot 301 is uniform, and avoiding the difference in drying effect caused by uneven temperature. The heating resistor 303 is embedded in the inner wall of the drying slot 301, and can directly heat the seeds in the slot, so that the seeds are heated more evenly. This avoids the situation of local overheating or insufficient drying that may occur in traditional drying methods, improves the uniformity and consistency of drying, and ensures the accuracy of the test results.
[0031] This specific embodiment is merely an explanation of the present invention and is not a limitation of the present invention. After reading this specification, those skilled in the art may make non-creative modifications to the present embodiment as needed. However, as long as they are within the scope of the claims of the present invention, they are protected by the patent law.
