Abstract
Description
Technical Field
[0001] This utility model relates to the field of cotton seed quality testing technology, and in particular to a quality testing device for cotton seeds. Background Technology
[0002] Cotton seeds are the reproductive organs of the cotton plant, mainly composed of the seed coat, embryo, and endosperm. The seed coat plays a protective role, preventing damage to the internal structure. The quality of cotton seeds directly affects the yield and quality of cotton. High-quality seeds should have high purity, high germination rate, and strong viability. Through scientific breeding and planting techniques, the quality of cotton seeds can be improved, thereby increasing the yield and quality of cotton.
[0003] The quality inspection device for cotton seeds aims to ensure they meet agricultural planting requirements by conducting comprehensive quality checks. However, this device faces several challenges in practical application. First, due to the electrostatic adsorption of cotton lint and tiny impurities, seeds often adhere frequently to the inner wall of the inspection channel. This not only hinders the smooth passage of seeds but also causes blockages during feeding, increasing cleaning and maintenance costs. Second, because cotton seeds vary in size, they need to be sorted after inspection, but existing devices lack mechanisms to distinguish seed sizes and cannot automate this task. Furthermore, cotton seeds easily clump together due to electrostatic adsorption, resulting in insufficient cleaning and further affecting overall inspection efficiency and effectiveness. These factors combined reduce the reliability and ease of operation of the device. Utility Model Content

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

Each distribution box has a mesh plate fixedly connected to its bottom and a discharge box fixedly connected to its top. The same inclined screening plate is fixedly connected to the top of each discharge box.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0022] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings.

Therefore, they should not be construed as limitations on this utility model.
[0023] Reference Figure 1-4A quality testing device for cotton seeds includes a mounting plate 1. Multiple support feet 2 are fixedly connected to the bottom of the mounting plate 1 to ensure the entire device can be stably placed on the required operating platform, thereby guaranteeing the stability of the device during operation and preventing operational errors caused by vibration. Multiple distribution boxes 3 are fixedly connected to the top of the mounting plate 1. The main function of these distribution boxes 3 is to initially distribute the cotton seeds to be tested. A mesh plate 10 is fixedly connected to the bottom of each of the multiple distribution boxes 3. This design can effectively screen out cotton seeds that are too small or damaged, allowing suitable cotton seeds to pass through the mesh below and enter the subsequent testing process. A discharge box 4 is fixedly connected to the top of each of the multiple distribution boxes 3. A screening plate 5 with the same inclined setting is fixedly connected to the top of each of the multiple discharge boxes 4. By setting the inclination angle, the material can slide down naturally under its own weight and appropriate vibration, which helps to further remove impurities and separate seed sizes. A motor 7 is fixedly connected to the outer wall of the leftmost distribution box 3, and the motor 7 is connected to a rotating mechanism. A pressure tank 13 is fixedly connected to the outer wall of the mounting plate 1, and the pressure tank 13 is connected to a pneumatic mechanism.
[0024] The rotating mechanism includes a rotating shaft 8 fixedly connected to the output end of the motor 7. The rotating shaft 8 passes through the side walls of multiple distribution boxes 3. Multiple stirring blades 9 are fixedly connected to the outer wall of the rotating shaft 8 located in the multiple distribution boxes 3. These stirring blades 9 are evenly distributed along the axial direction and can fully stir the cotton seeds in the distribution boxes 3. A first convex plate 11 and a second convex plate 12 are fixedly sleeved on the outer wall of the rotating shaft 8 located outside the distribution boxes 3. These two convex plates work together with the motor 7. The first convex plate 11 intermittently impacts the screening plate 5 to facilitate the feeding of cotton seeds, and the second convex plate 12 intermittently presses the pressing plate 16.
[0025] The pneumatic mechanism includes a sliding plate 14 slidably connected to the inner wall of the pressure tank 13. The sliding plate 14 can move up and down inside the pressure tank 13. A pressure column 15 is fixedly connected to the top of the sliding plate 14. The pressure column 15 passes through the top of the pressure tank 13 and is connected to a pressing plate 16. This means that pressure can be directly transmitted to the sliding plate 14 by pressing the pressing plate 16. A connection port 18 is provided on the bottom side wall of the pressure tank 13. A connecting pipe 19 is fixedly connected to the inner side wall of the connection port 18. Multiple air outlet pipes 20 are connected to the top of the connecting pipe 19. The connecting pipe 19 needs to be sealed to the connection port 18 and the air outlet pipes 20 to ensure that there is no gas leakage, thereby effectively ensuring the normal operation of the system. The multiple air outlet pipes 20 are respectively connected to the bottom of multiple distribution boxes 3. Each air outlet pipe 20 is ultimately connected to the bottom of a different distribution box 3, forming a complete gas conduction system.
[0026] A telescopic spring 17 is fitted on the outer wall of the lower pressure column 15. The two ends of the telescopic spring 17 are fixedly connected to the bottom of the pressing plate 16 and the top of the pressure tank 13, respectively. Specifically, in the initial state, the spring is in a naturally contracted state due to its own elasticity. When a pressing operation is required, the external force will cause the pressing plate 16 to move downward and compress the telescopic spring 17. Once the external force disappears, the telescopic spring 17 will immediately drive the pressing plate 16 to return to its original height.
[0027] Each of the multiple air outlet pipes 20 is equipped with a baffle 21 at the top. The baffle 21 is installed to prevent external substances or foreign objects from falling into the air outlet pipe 20, ensuring the smooth flow and cleanliness of the airflow path during equipment operation.
[0028] The screening plate 5 has two symmetrically arranged side plates 6 fixedly connected to its side wall, which effectively restricts and controls the material flow direction and avoids accidental deviation during vibration.
[0029] The apertures on the sieve plate 5 increase sequentially, mainly for classifying and screening cotton seeds of different sizes according to particle size. This allows smaller seeds to pass through the upper sieve plate 5 with smaller apertures first, while larger seeds are retained on the lower sieve plate 5 with larger apertures.
[0030] The specific working principle of this utility model is as follows:
[0031] In its initial state, when this device is used, the user first pours a batch of cotton seeds onto the inclined sieve plate 5 at the top. Its unique inclination angle ensures that the material can slide smoothly and evenly into each distribution box 3. At this time, the motor 7, which is fixedly installed on the outside of the left distribution box 3, will be started. Driven by the rotating mechanism, a vibration effect is generated. This not only helps the material in the feed box 4 to fall more smoothly into each distribution box 3, but also, in conjunction with the angle of the sieve plate 5, performs preliminary filtering and removal of lighter or non-standard large particles.
[0032] At the same time, the rotating shaft 8 rotates, driving the stirring blade 9 to rotate, stirring and cleaning the cotton seeds in the dispensing box 3, so that the cotton seeds are fully mixed with the cleaning water, and the stirring of the seeds generates friction to clean them.
[0033] At the same time, the second convex plate 12 rotates to press the pressing plate 16, which applies force to the sliding plate 14. The sliding plate 14 moves down under the force and compresses the air in the pressure tank 13 to generate airflow. This airflow is quickly guided into each air outlet pipe 20 connected to the distribution box 3 through the connecting pipe 19. This controls and manages the cotton seeds to blow air to generate upward bubbles throughout the cleaning process, thereby pushing the cleaned seeds and facilitating the accumulation of cotton seeds, thus making the cleaning more thorough.
[0034] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
