Description

Technical Field

[0001] This utility model relates to the field of soybean technology, and more specifically, to a water selection mechanism for soybean seed production. Background Technology

[0002] Soybean seed production refers to the process of producing high-quality soybean seeds, a crucial step in agricultural science. Soybean seed water separators are essential equipment for screening and purifying soybean seeds, playing a key role in improving seed quality during the production process. These separators utilize the buoyancy of water to separate impurities and underdeveloped seeds, ensuring that the final product is healthy, plump soybean seeds with a high germination rate.

[0003] Traditional seed selection methods primarily rely on manual picking or simple mechanical separation, such as winnowing and sieve filtration. However, these methods are ineffective at identifying certain types of defects (such as internal lesions or recessive genetic problems). In contrast, water sorting is an effective method for distinguishing between good and bad seeds based on density differences. It utilizes the difference in buoyancy between healthy and inferior seeds in water for selection.

[0004] However, traditional soybean water sorting methods require a lot of manpower, especially when processing large quantities of seeds, which is very labor-intensive. Utility Model Content

[0005] In order to overcome the disadvantages of traditional water separation which requires a lot of manual operation and results in high labor intensity, the purpose of this utility model is to provide a water separation mechanism for soybean seed production.

[0006] A water selection mechanism for soybean seed production includes a fixed frame, a first collection frame, a second collection frame, a fixed plate, an electric slide rail, a connecting rod, a scraper, and a connecting spring. The fixed frame is divided into left and right chambers. The first collection frame is slidably connected to one chamber, and the second collection frame is slidably connected to the other chamber. Fixed plates are connected to both the front and rear sides of the fixed frame, and electric slide rails are connected to both fixed plates. Connecting rods are connected to the sliders of the electric slide rails. A scraper is slidably connected between the front and rear connecting rods. The bottom of the scraper is inclined, and the side of the scraper closer to the second collection frame is lower than the side farther away from the second collection frame. A filter screen is provided at the bottom of the scraper. A connecting spring is connected between the connecting rod and the scraper.

[0007] Furthermore, it also includes connecting blocks and guide blocks. Guide blocks are connected to the sides of the two fixed plates that are close to each other, and connecting blocks are connected to the connecting rods. The connecting blocks are higher than the bottom of the guide blocks.

[0008] Furthermore, it also includes a guide frame, which is connected to the first collection frame, and the bottom inner diameter of the guide frame is smaller than the top inner diameter.

[0009] Furthermore, it also includes an air blower, which is connected to the outer wall of the fixed frame, with the blowing end of the air blower passing through the outer wall of the fixed frame.

[0010] Furthermore, it also includes a protective frame, a sieve plate, a placement cylinder, a servo motor, and a metering shaft. The protective frame is connected to the fixed frame, the placement cylinder is connected to the protective frame, the servo motor is installed on the outer wall of the protective frame, the output shaft of the servo motor passes through the protective frame, the metering shaft is connected to the output shaft of the servo motor, the metering shaft is rotatably connected to the protective frame, and the sieve plate is slidably connected inside the protective frame.

[0011] Furthermore, it also includes a vibrator, which is installed inside the protective frame and comes into contact with the screen plate.

[0012] The beneficial effects are as follows: This utility model is equipped with an electric slide rail, a connecting rod, a scraper, a connecting block, and a guide block. Based on the different floating and sinking characteristics of healthy seeds and inferior seeds in water, it can send floating inferior soybeans into the second collection frame for collection, while healthy soybeans sink to the bottom of the water. No manual operation is required, realizing automatic screening and classification of inferior and healthy soybeans, reducing the workload of workers, and improving the efficiency of soybean seed production.

Detailed Implementation

[0019] The preferred technical solution of this utility model will be described in detail below with reference to the accompanying drawings.

[0020] A soybean seed production water selection mechanism, such as Figures 1-5As shown, the device includes a fixed frame 1, a guide frame 2, a first collection frame 3, a second collection frame 4, a fixed plate 5, an electric slide rail 6, a connecting rod 8, a scraper 9, a connecting spring 10, a connecting block 11, a guide block 12, and an air blower 13. The fixed frame 1 is divided into two chambers, left and right. The first collection frame 3 is slidably connected to one chamber, and the first collection frame 3 has filter holes. The second collection frame 4 is slidably connected to the other chamber. The guide frame 2 is fixedly connected to the top of the first collection frame 3. The bottom inner diameter of the guide frame 2 is smaller than its top inner diameter. Fixed plates 5 are fixedly connected to both the front and rear sides of the fixed frame 1. Electric slide rails 6 are fixedly connected to the top of each fixed plate 5. Each slider 7 is fixedly connected to a connecting rod 8. A scraper 9 is slidably connected between the front and rear connecting rods 8. The bottom of the scraper 9 is inclined. The side of the scraper 9 closer to the second collection frame 4 is lower than the side farther away from the second collection frame 4. A filter screen is provided at the bottom of the scraper 9. A connecting spring 10 is fixedly connected between the connecting rod 8 and the scraper 9. The connecting spring 10 is a helical spring. A guide block 12 is fixedly connected to the side of the two fixed plates 5 that are close to each other. A connecting block 11 is fixedly connected to the top of each connecting rod 8. The connecting block 11 is higher than the bottom of the guide block 12. An air blower 13 is fixedly connected to the outer wall of the fixed frame 1. The air blowing end of the air blower 13 passes through the outer wall of the fixed frame 1.

[0021] like Figure 1 , Figure 2 and Figure 5 As shown, it also includes a protective frame 14, a sieve plate 15, a placement cylinder 16, a vibrator 17, a servo motor 18, and a metering shaft 19. The protective frame 14 is fixedly connected to the top left side of the fixed frame 1. The placement cylinder 16 is fixedly connected to the top of the protective frame 14 and communicates with the protective frame 14. The servo motor 18 is installed on the outer wall of the protective frame 14. The output shaft of the servo motor 18 passes through the protective frame 14. The metering shaft 19 is fixedly connected to the output shaft of the servo motor 18 and is rotatably connected to the protective frame 14. The sieve plate 15 is slidably connected inside the protective frame 14. The sieve plate 15 is inclined, with the side of the sieve plate 15 closer to the protective frame 14 lower than the side away from the protective frame 14. The sieve plate 15 has sieve holes with an inner diameter smaller than the diameter of a healthy soybean. The distance between the blades of the metering shaft 19 and the sieve plate 15 is smaller than the diameter of the soybean. The vibrator 17 is installed inside the protective frame 14 and is in contact with the sieve plate 15.

[0022] Initially, the right chamber of the fixed frame 1 is filled with water, the water level being lower than the left chamber but higher than the bottom of the scraper 9. When water separation of soybeans is required, the soybeans are poured into the placement cylinder 16. The soybeans fall onto the sieve plate 15 through the placement cylinder 16. The metering shaft 19 prevents the soybeans from falling into the right chamber along the sieve plate 15. The servo motor 18 drives the metering shaft 19 to rotate, thus positioning the soybeans between adjacent blades of the metering shaft 19. Under the rotation of the metering shaft 19, the soybeans between adjacent blades on the metering shaft 19 move along the sieve plate 15, thereby achieving quantitative feeding. The sieve plate 15 can perform preliminary screening of the soybeans. Defective soybeans and dust fall through the sieve holes of the sieve plate 15 into the second collection frame 4. The vibrator 17 causes the sieve plate 15 to vibrate up and down, thereby improving the screening efficiency of the sieve plate 15 and preventing soybeans and dust from clogging it. Soybeans that have undergone the initial screening slide along the sieve plate 15 into the first collection frame 3. The guide frame 2 ensures that the soybeans fall completely into the first collection frame 3. An air blower 13 blows air bubbles into the water, causing the water to churn and ensuring that the soybeans are in full contact with the water. This prevents soybeans from accumulating on the surface, which would lead to low water separation efficiency. Low-density, inferior soybeans float on the surface, while high-density, healthy soybeans sink to the bottom. Then, an electric slide... The slider 7 of rail 6 drives the connecting rod 8 to move closer to the left chamber, causing the scraper 9 to scrape the soybeans floating on the water surface towards the left chamber. When the connecting block 11 approaches the guide block 12, the connecting block 11 slides upward along the guide block 12, the connecting spring 10 is stretched, and the scraper 9 slides upward along the connecting rod 8, so that the bottom of the scraper 9 is higher than the left chamber, causing the soybeans on the scraper 9 to move upward and fall into the left chamber. The soybeans falling into the left chamber are inferior soybeans, thus completing the water separation of soybeans. Then, the electric slide rail 6 drives the scraper 9 to move to the right to reset, and the connecting block 11 moves away from the guide block 12, causing the connecting spring 10 to return to its original state. The scraper 9 moves downwards to reset, eliminating the need for manual operation and enabling automatic sorting and classification of inferior and healthy soybeans. This reduces the workload of workers and improves the efficiency of soybean seed production. When soybeans need to be removed from the first collection box 3 and the second collection box 4, the first collection box 3 is pulled upwards, and the water in the first collection box 3 falls into the right chamber through the filter hole. The healthy soybeans in the first collection box 3 are then collected. The second collection box 4 is then slid to the right and pulled out, and the inferior soybeans in the second collection box 4 are then collected. This completes the collection of soybeans. The first collection box 3 and the second collection box 4 are then reset to facilitate the next water selection.
