Description

Technical Field

[0001] This utility model relates to the field of seed screening technology, specifically a seed selection machine for screening high-quality, high-protein soybean varieties. Background Technology

[0002] High-quality seeds are the foundation for high yield and quality soybeans. The breeding of new high-quality, high-protein soybean varieties requires screening for plump, uniform-sized seeds free from pests and diseases to ensure uniform emergence, robust growth, and increased soybean yield and protein content. Using a seed selector can accurately screen for seeds that meet these requirements, ensuring high-quality and high-yield soybeans.

[0003] With the development of agricultural modernization, soybean cultivation is gradually moving towards large-scale and intensive farming. Large-scale cultivation requires a large quantity of high-quality seeds, but traditional manual screening methods are inefficient and inaccurate, failing to meet the quantity and quality demands of large-scale cultivation. The emergence of seed sorting machines enables efficient and rapid seed screening, meeting the needs of large-scale cultivation.

[0004] An investigation revealed that a Chinese utility model patent (publication number: CN219187715U) discloses an auxiliary feeding mechanism for a seed sorting machine. The mechanism includes a machine body and a feeding hopper. The feeding hopper is mounted above the machine body, with its outlet facing the machine body. A baffle is mounted on the side wall of the feeding hopper, and a distributing port is provided near the outlet on the baffle. A rotating mechanism is installed inside the distributing port. A bottom groove is provided on the side wall of the machine body, and a translation mechanism is installed on the bottom groove. In this application, the worker can pour all the seeds from the bag onto the baffle at once. By driving an electric push rod, the translation mechanism can drive the rotating mechanism to rotate, allowing the seeds to enter the machine body in an orderly manner through the outlet. Furthermore, the falling speed of the seeds can be adjusted, eliminating the need for manual control by the worker. This improves sorting efficiency without putting strain on the worker's body.

[0005] Although the aforementioned patent eliminates the need for manual control by adjusting the angle of the rotating flap, thus improving screening efficiency without placing additional burden on workers' bodies, it may miss some impurities when screening for small-diameter impurities or impurities similar in size to soybean seeds. Alternatively, when grading seeds by size, some seeds at the grading boundary may be misclassified.

[0006] Therefore, this utility model provides a high-quality, high-protein soybean seed screening machine to solve the above problems. Utility Model Content

[0007] (a) Technical problems to be solved

[0008] This invention provides a high-quality, high-protein soybean seed screening machine, which aims to solve the problems mentioned in the background art.

[0009] (II) Technical Solution

[0010] To achieve the above objectives, this utility model provides the following technical solution: It includes a frame, with a horizontal support bracket at the bottom of one side surface of the frame. A motor is fixedly mounted on the upper surface of the horizontal support bracket by bolts. A transmission wheel is fixedly mounted on one output end of the motor. A transmission belt is fitted onto the outer arc surface of the transmission wheel. A shaft is fixedly mounted on one side of the transmission belt at the top of the transmission wheel. A central shaft is fixedly mounted at one end of the shaft. A traction rod is movably connected to one edge of one surface of the central shaft via a rotating shaft. A mounting frame A is movably connected to one side surface of the traction rod via a rotating shaft. A connecting groove is formed on one side surface of the traction rod. A linkage rod is slidably hinged to the inner side wall of the connecting groove. A mounting frame B is movably connected to the side of the linkage rod away from the traction rod via a rotating shaft. A coarse screen is fixedly mounted on the surface of the mounting frame A, and a fine screen is fixedly mounted on the upper surface of the mounting frame B.

[0011] As a preferred technical solution of this application, the lower surface of the mounting frame B is movably snapped with an inclined frame, one side edge of the inclined frame is movably connected to one side of the frame via a pivot, and the upper surface of the inclined frame is fixedly mounted with a material distribution plate by bolts.

[0012] As a preferred technical solution of this application, the lower surface of the material distribution plate is provided with inclined edges on both sides, the inclined edges are placed on the surface of the fine screen, and the inclined frame is provided with bent ends on both sides.

[0013] As a preferred technical solution of this application, a feeding hopper is fixedly installed on one side surface of the bent end, and connecting parts are provided on both sides of the rear end of the feeding hopper. The feeding hopper is fixedly installed on the inclined frame through the connecting parts at the rear end.

[0014] As a preferred technical solution of this application, a vibration spring is fixedly installed on the lower surface of the inclined frame, and one end of the vibration spring is connected to an abutment plate.

[0015] As a preferred technical solution of this application, a support plate is fixedly installed at one end of the vibration spring through the abutment plate. There are three support plates, one of which is fixedly installed on the frame, and the upper surface of the other support plate is fixedly installed with a vibrator.

[0016] (III) Beneficial Effects

[0017] By combining coarse and fine screens with mesh sizes customized according to common soybean dimensions, large impurities can be quickly filtered out, allowing most normal soybean seeds to pass through smoothly. Seeds that have undergone preliminary screening by the coarse screen are then subjected to high-frequency vibration by the fine screen, where tiny particles that do not meet the standards are precisely identified and separated, thus improving the purity of soybean seeds to a certain extent and ensuring that the final selected seeds have fullness. The combination of these two methods allows for comprehensive screening of soybean seeds from different dimensions, avoiding the omission of impurities or the grading of seeds by size.

A linkage rod 8 is slidably hinged to the inner wall of the connecting groove 601. A mounting frame B9 is movably connected to the side of the linkage rod 8 away from the traction rod 6 via a rotating shaft. A coarse screen 701 is fixedly installed on the surface of the mounting frame A7. A fine screen 901 is fixedly installed on the upper surface of the mounting frame B9. An inclined frame 10 is movably snapped onto the lower surface of the mounting frame B9. One side edge of the inclined frame 10 is movably connected to one side of the frame 1 via a rotating shaft. A material distribution plate 11 is fixedly installed on the upper surface of the inclined frame 10 by bolts. Both sides of one side of the lower surface of the material distribution plate 11 are provided with inclined edges 111, which are placed on the surface of the fine screen 901. Both sides of the inclined frame 10 are provided with bent ends 1011. A feeding hopper 12 is fixedly installed on one side of the bent end 1011. Both sides of the rear end of the feeding hopper 12 are provided with connecting parts 121. The feeding hopper 12 is fixedly installed on the inclined frame 10 via the rear connecting parts 121.

[0026] When conducting soybean seed screening, the workers first pour the seeds to be screened onto the coarse screen 701. Then, they start the motor 2 mounted on the top of the traction rod 6. Once the motor 2 is running, it quickly drives the transmission wheel 3 below to rotate at high speed. As the transmission wheel 3 continues to rotate, the shaft rod 5 rotates synchronously at its center position. During this rotation, the change in wheelbase caused by the rotation, combined with the connecting action of the traction rod 6, controls the smooth reciprocating movement of the mounting frame A7 on the frame 1. Simultaneously, a connecting... The linkage rod 8 of the groove 601 is slidably engaged therein. When the pulling rod 6 moves back and forth continuously, the linkage rod 8 adjusts the wheelbase accordingly in the connecting groove 601, thereby driving the mounting frame B9 at the bottom to move together. During this process, the soybean seeds located at the top of the coarse screen 701 begin to undergo initial screening under the action of the back and forth movement of the mounting frame A7. Those impurities that are too large are effectively intercepted by the coarse screen 701, while the vast majority of normal-sized soybean seeds pass smoothly through the mesh and fall orderly into the mounting frame B9 below along the slope of the coarse screen 701.

[0027] A vibration spring 13 is fixedly installed on the lower surface of the inclined frame 10. One end of the vibration spring 13 is connected to an abutment plate 14. A support plate 15 is fixedly installed on the end of the vibration spring 13 that passes through the abutment plate 14. There are three support plates 15. One support plate 15 is fixedly installed on the frame 1, and a vibrator 16 is fixedly installed on the upper surface of the other support plate 15.

[0028] The seeds entering the mounting frame B9 move continuously under the drive of the linkage rod 8. At the same time, the vibrator 16 starts to work, driving the top abutment plate 14. With the high-frequency vibration of the vibrator 16, the vibration springs 13 connected to the four corners of the support plate 15 continuously generate elastic deformation, which in turn drives the fine screen 901 inside the mounting frame B9 to continuously vibrate at high frequency. The mesh of the fine screen 901 is extremely fine. Under high-frequency vibration, it can remove shriveled seeds, broken seeds and other fine impurities that are too small, thus performing secondary fine screening of soybean seeds. During the screening process, as the mounting frame B9 moves, the angle of the inclined frame 10 changes continuously. It flips up and down around the connection point with the frame 1. The high-quality soybean seeds that have undergone secondary screening slide down the slope of the inclined frame 10 in an orderly manner into the collection device below, completing the entire screening process.

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.
