Description

Technical Field

[0001] This utility model relates to the field of seed screening technology, specifically a pelleted seed grading and selection machine. Background Technology

[0002] Seed pelleting is a process in which crop seeds are treated to form a hard, round outer shell. This process is commonly referred to as "pilling." This treatment method is primarily used to improve seed sowing efficiency and germination rate. Before pelleting, seeds need to be graded (usually based on seed size) to remove inferior and substandard seeds, ensuring that the final pelleted seeds are of high quality and have a high germination rate.

[0003] Existing grading and screening devices typically use vibrating screens to grade seeds, employing different mesh sizes to separate seeds of varying sizes. However, existing vibrating screening devices still have the following problems during use:

[0004] The seeds to be screened are usually mixed with light impurities such as straw and dust. In existing technology, a blower is generally used to remove impurities by airflow from the seeds falling onto the screen. Specifically, during the process of the seeds falling, the airflow generated by the blower blows out the light impurities, thereby achieving the purpose of separating the light impurities before vibration screening. However, the time that the seeds are in the falling state is generally short, so the effective impurity removal time is short, resulting in an unsatisfactory effect in removing light impurities.

[0036] A spring 30 is sleeved around the optical axis 29. The spring 30 is located between the guide plate 15 and the connecting plate 28, and the two ends of the spring 30 are fixedly connected to the guide plate 15 and the connecting plate 28 respectively.

[0037] A cam 27 is fixedly installed on the output shaft end of motor 3 26. The periphery of the cam 27 slides in contact with the side of the connecting plate 28 away from the guide plate 15.

[0038] The blower assembly includes multiple mounting slots 22. Multiple mounting slots 22 are arrayed along the length of the side of the side baffle 16, and a fan 23 is installed in the mounting slots 22.

[0039] The dust collection assembly includes an L-shaped guide tube 18 fixedly installed at the end of the guide plate 17 away from the guide plate 15. A collection pipe 19 is fixedly installed through the end of the L-shaped guide tube 18 away from the guide plate 17. A motor 20 is fixedly installed at the end of the collection pipe 19 near the hopper 21. The output shaft of the motor 20 rotates through the end of the collection pipe 19 to the collection pipe 19 and is fixedly connected to a mounting shaft.

[0040] The end of the collecting pipe 19 away from the motor 20 is an open structure, and a filter bag is detachably and fixedly installed thereon.

[0041] The screening mechanism includes a motor 14, a screen frame 4, and a sliding column 6. The sliding column 6 is fixedly connected to both sides of the top surface of the workbench 1.

[0043] When using this utility model:

[0044] Before screening, place a collection box below the through channel 3;

[0045] Then start the fan 23, motor 14, motor 3 26 and motor 20; then put the seeds into the hopper 21. The seeds in the hopper 21 fall through the bottom opening to the higher end of the top surface of the guide plate 15, and then slide along the length of the guide plate 15 until they fall into the screen frame 4.

[0046] As the seeds slide on the guide plate 15:

[0047] The airflow generated by the fan 23 continuously blows the seeds on the guide plate 15. Under the guidance of the guide plate 17, the airflow enters the L-shaped guide tube 18 and then passes through. Light impurities in the seeds will enter the L-shaped guide tube 18 with the airflow and then fall into the collection tube 19. The impurities in the collection tube 19 are collected in the filter bag.

[0048] Motor 26 drives cam 27 to rotate. The rotation of cam 27, through the connection plate 28 and spring 30, causes multiple optical shafts 29 to reciprocate and slide, thereby causing the lifting plate 24 to reciprocate and slide in the groove 25. When the seeds pass through the lifting plate 24, they will be bounced up to a certain height. The bounced seeds are conducive to the airflow carrying out light impurities. The seeds will be bounced up multiple times as they move from the higher end of the guide plate 15 to the lower end of the guide plate 15, thereby improving the impurity removal effect. In addition, the reciprocating bouncing action of multiple lifting plates 24, combined with the slope of the guide plate 15, can ensure the stability of the seeds entering the screen frame 4 and avoid the seeds from clogging on the guide plate 15.

[0049] The rotation of motor 20 drives the auger conveyor structure in the collection pipe 19 to operate, which can actively guide impurities in the collection pipe 19 into the filter bag, thereby improving the dust collection effect.

[0050] The rotation of motor 14 drives the connecting rod 13 to rotate. The rotation of the connecting rod 13, through the cooperation of the drive column 12 and the slide 11, can drive the screen frame 4 to vibrate up and down under the limiting action of the slide column 6. Therefore, the seeds falling from the lower end of the guide plate 15 into the screen frame 4 will be vibrated and screened. Qualified seeds pass through the screen plate 8 and fall into the collection box below the channel 3.

[0051] In the feeding mechanism 10 of this utility model, through the combined use of the guide plate 15, side baffle 16, blowing assembly, guide plate 17 and dust collection assembly, it is possible to remove light impurities in the seeds before they enter the sieve frame 4 while feeding them. Compared with the existing airflow impurity removal method, the effective airflow impurity removal time of this utility model is greatly increased, significantly improving the impurity removal effect. Furthermore, the dust collection assembly can collect impurities at the separation point, facilitating subsequent processing.

[0052] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
