Secondly, some devices cannot adapt to the separation requirements of different seeds, and the vibration intensity may not be precisely controlled, affecting the separation effect and the service life of the device. Finally, during the separation process of some devices, the generated impurities will be scattered in the working area, affecting the working environment and even possibly the normal operation of the device. The impurities may enter the moving parts of the device, accelerating wear and reducing the service life of the device. Operators exposed to the dusty environment may increase the risk of health problems such as respiratory diseases. Summary of the Utility Model

[0031] Please refer to Figures 1-5 , a corn seed separation device, including a screening box 1 arranged from top to bottom, a vibration separation mechanism and a plurality of spring adjustment mechanisms. The vibration separation mechanism includes a vibration motor 2, a plurality of first springs 4, a plurality of bottom frames 5, a plurality of top frames 7 and a vibration frame 3. The vibration motor 2 is installed at the upper end of the vibration frame 3. One end of the first spring 4 is connected to the screening box 1 through the top frame 7, and the other end of the first spring 4 is connected to the vibration frame 3 through the bottom frame 5. A plurality of spring adjustment mechanisms are arranged on the periphery of the lower end of the vibration frame 3. The spring adjustment mechanism includes a turning handle 8, an adjustment rod 9, an upper bearing plate 10, a second spring 6, a lower bearing plate 11 and a plurality of adjustment plates 12. The turning handle 8 is arranged at one end of the adjustment rod 9. The other end of the adjustment rod 9 passes through the upper bearing plate 10 and is connected to the lower bearing plate 11. A plurality of adjustment plates 12 and the second spring sleeve 6 are sleeved on the adjustment rod 9. A plurality of adjustment plates 12 and the second spring 6 are arranged between the upper bearing plate 10 and the lower bearing plate 11. The adjustment rod 9 is threadedly connected to the upper bearing plate 10, and the upper bearing plate 10 is connected to the vibration frame 3.

[0032] Specifically, a scraper 17 is arranged in the screening box 1. Sliders 18 are arranged on the opposite sides of the scraper 17. A handle 19 is arranged at one end of the slider 18. Slide rails 20 are arranged on both sides of the screening box 1. The slider 18 is slidably connected to the slide rail 20. A separation funnel 21 is arranged at one end of the screening box 1 away from the dust removal box. The separation funnel 21 is used to collect the screened corn seeds. A diagonally braced frame 22 is arranged on one side of the bottom frame 5 in a detachable connection. The diagonally braced frame 22 is arranged between the screening box 1 and the vibration frame 3. Side columns 23 are arranged on the periphery of the vibration frame 3. A side bearing plate 24 is arranged on one side of the upper bearing plate 10. The side bearing plate 24 is connected to the side column 23. The spring adjustment mechanism is arranged on the periphery of the lower end of the vibration frame 3. A support frame 25 is arranged below the lower bearing plate 11. The support frame 25 is used to support the spring adjustment mechanism.

[0033] Specifically, the dust suction mechanism includes a dust removal box 13, a plurality of dust removal pipes 14, a dust removal fan 15, and a dust discharge pipe 16. The dust removal box 13 is arranged at the upper end on one side of the screening box 1. The plurality of dust removal pipes 14 and the dust removal fan 15 are respectively arranged on opposite sides of the screening box 13. One end of the dust removal pipe 14 is communicated with the dust removal box 13, and the other end of the dust removal pipe 14 extends towards the screening box 1 away from the dust removal box 13. The dust removal fan 15 is used to fan to form an adsorption air flow. One end of the dust discharge pipe 16 is communicated with the bottom of the dust removal box 13, and the end of the dust discharge pipe 16 away from the dust removal box 13 extends towards the ground.

[0034] Specifically, when the vibration separation mechanism needs to operate, when the device starts, the vibration motor 2 starts to work and generates vibration. The vibration is transmitted to the chassis 5 through the vibration frame 3 and then to the top frame 7 through the second spring 6, so that the seeds in the screening box 1 are affected by the vibration. Due to the different sizes, densities, and dust impurities of the seeds, the vibration causes the lighter or smaller impurities to be separated from the seeds and discharged through the separation funnel 21 at the bottom of the screening box 1.

[0035] Specifically, when the spring adjustment mechanism needs to operate, by rotating the handle 8, the adjustment rod 9 moves up and down, and the adjustment plate 12 is locked step by step, thereby adjusting the stiffness coefficient of the first spring 6. According to the characteristics of the seeds and the separation requirements, the operator can adjust the stiffness of the spring to adapt to different vibration intensities and separation effects. For example, by changing the stiffness coefficients of the front two groups of springs and changing the pre-tightening force of the first spring 6, when the screening box 1 vibrates, a vibration tendency appears, improving the separation effect.

[0036] Specifically, when the dust suction mechanism needs to operate, when the screening box 1 vibrates, lighter dust appears. At this time, when the device is running, the dust removal fan 15 starts to work, generating negative pressure. Through the dust removal pipe 14, the air flow generated by the fan changes the pressure in the dust removal box 13, sucking the lighter impurities generated during the screening process into the dust removal box 13. The impurities are filtered in the dust removal box 13 and then discharged through the dust discharge pipe 16.

[0037] The process of realizing the present utility model is as follows: Load the corn seeds into the screening box 1, start the vibration separation mechanism and the dust suction mechanism. The vibration generated by the vibration motor 2 separates the impurities in the seeds and discharges them through the separation funnel 21 at the bottom of the screening box 1. The operator controls the sliders 18 on both sides of the scraper 17 through the handle 19 and slides on the slide rail 20 to adjust the position of the scraper 17 to help the seeds flow and separate. According to the separation effect, adjust the stiffness coefficient of the second spring 4 through the spring adjustment mechanism to optimize the vibration separation effect. The dust suction mechanism works, sucking the separated impurities into the dust removal box 13 and discharging them through the dust discharge pipe 16. After the separation process is completed, turn off the device and clean the screening box 1 and the dust removal box 13.

[0038] Among all the solutions mentioned above, for those involving the connection between two components, welding, the connection with bolts and nuts, bolt or screw connection, or other well-known connection methods can be selected according to the actual situation, which will not be elaborated one by one here.
