[0026] Specifically, such as Figure 1 , Figure 2 and Figure 4 As shown, when feeding corn, after the corn is introduced into the inside of the feeding box 9, the corn inside can automatically move to the right by using the inclined feeding box 9 and the vibration of the vibrating box 3. Through multiple sets of discharge pipes 11 fixed at equal intervals at the bottom of the connecting cover 10, the corn can be evenly distributed downwards and discharged to different positions on the top right side of the screen plate 6 for efficient screening.

[0027] A housing 14 is fixedly installed on the top of the base 2, and a connecting pipe 13 is fixed to the rear end of the housing 14. Corrugated pipes 12 are fixedly installed on the top of both sides of the connecting pipe 13. Dust hoods 7 are fixed on both sides of the top of the rear end of the vibration box 3, and the front end of the dust hood 7 penetrates the interior of the rear end of the vibration box 3. A screen 8 is fixed inside the front end of the dust hood 7. A dust collection cylinder 21 is installed inside the housing 14. A negative pressure fan 22 is fixedly installed at the front end inside the housing 14.

[0028] The front end of the connecting pipe 13 passes through the interior of the rear end of the chassis 14 and is fixed between the front end of the dust collection cylinder 21. The top ends of the two sets of corrugated pipes 12 are fixedly connected to the rear ends of the two sets of dust collection hoods 7 respectively. The dust collection hoods 7 are connected to the interior of the corrugated pipes 12, and the corrugated pipes 12 are connected to the interior of the connecting pipe 13.

[0029] Specifically, such as Figure 1 and Figure 3 As shown, the negative pressure fan 22 can be started to generate negative pressure inside the casing 14. Then, the two sets of dust extraction hoods 7 connected together can perform suction operations. Some scattered dust generated during the screening process inside the vibrating box 3 can be directly extracted from the dust extraction hood 7 and introduced into the dust collection cylinder 21 through the corrugated pipe 12 and the connecting pipe 13 for collection, thereby reducing dust pollution during the screening process.

[0030] Support legs 1 are fixed at the four corners of the bottom of the base 2, and a support 15 is fixed on one side of the support leg 1. The support 15 is internally threaded and rotatably connected to a screw rod 17, and a handle 16 is fixed at the top of the screw rod 17. A universal caster 18 is provided at the bottom of the support 15. The support 15 is symmetrically arranged about the vertical center line of the base 2. The bottom end of the screw rod 17 passes through the interior of the support 15 and is movably connected to the top of the universal caster 18.

[0031] Specifically, such as Figure 1 As shown, on the four sets of support legs 1 at the bottom, rotating the handle 16 drives the lead screw 17 to rotate and extend the universal caster 18 downwards.

[0033] Working Principle: During the use of this corn seed selection and screening mechanism, the corn material is fed into the feeding box 9. Utilizing the inclined feeding box 9 and the vibration of the vibrating box 3, the corn material automatically moves to the right. Multiple sets of discharge pipes 11, evenly spaced at the bottom of the connecting cover 10, distribute the corn material evenly downwards to different positions on the right side of the top of the screen plate 6 for efficient screening. Qualified corn kernels are discharged from the top discharge port 4 after being screened by the screen plate 6, while fine dust particles and impurities are discharged from the bottom discharge port 4. Simultaneously, the negative pressure fan 22 can be activated during screening, generating negative pressure inside the machine housing 14. This negative pressure is then extracted by two connected dust extraction hoods 7. Some loose dust generated during screening inside the vibrating box 3 is directly extracted from the dust extraction hoods 7 and collected in the dust collection cylinder 21 through the corrugated pipe 12 and connecting pipe 13, effectively reducing dust pollution during the screening process.
