[0002] Corn screening refers to the process of separating corn impurities and particles of different sizes through a sifter to achieve the purpose of grading corn and removing impurities. During the corn screening process, different specifications of screening meshes can be used for screening according to the size and quality of the particles to ensure the screening effect. The screened corn can be used for different processing and uses, such as food processing, feed production, etc.

[0003] For example, the patent with publication number CN210098191U specifically discloses a multi-stage sorting equipment, including a base, a vibration motor, a bracket, a vibration rod, a first support plate, a second support plate, a third support plate, a first filter box, a first filter hole, a second filter box, and a second multi-filter hole. The utility model is connected to the bracket through a vibration motor. When the vibration motor is running, the first support plate, the second support plate and the third support plate on the bracket vibrate with the bracket. Since the diameters of the filter holes on each support plate are different, the larger drugs remain on the first support plate, thereby realizing the screening of drugs of different specifications, greatly improving the screening efficiency.

[0004] When the above-mentioned patented device is screening corn kernels, the screening screen is in a shaking state, which may easily cause the corn kernels to fail to fall accurately into the screen when falling after screening, and the corn kernels that fall outside need to be cleaned up by staff.

[0005] Therefore, it is necessary to provide a multi-stage sorting device to solve the above problems.

[0006] It should be noted that the above information disclosed in this Background section is only for understanding the background technology of the present application concept, and therefore, it may contain information that does not constitute the prior art. Utility Model Content

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts should fall within the scope of protection of this application.

[0026] like Figure 1-5 As shown, the present application provides a multi-stage sorting device, including a base 1;

[0027] A driving mechanism 2 is installed on the base 1, and the driving mechanism 2 includes a vibration motor 21 installed on the upper surface of the base 1. The vibration motor 21 is used to drive the bracket 41 to vibrate. The driving mechanism 2 includes a capstan 22 fixedly connected to the output end of the vibration motor 21. The surface of the capstan 22 is fixedly connected to a rocker 23. The arc surface of the rocker 23 is rotatably connected to a vibration plate 24. The surface of the vibration plate 24 is rotatably connected to a connecting block 25. When corn kernels need to be screened, the staff pours the corn kernels into the first sieve 44 on the top layer of the bracket 41, and then starts the vibration motor 21 to drive the capstan 22 to rotate. While the capstan 22 rotates, it drives the vibration plate 24 to move along the rocker 23 on the capstan 22, and the vibration plate 24 pushes the bracket 41 to shake;

[0028] A support mechanism 3 is installed on the base 1, and the support mechanism 3 includes a support rod 31 installed on the upper surface of the base 1, and the support rod 31 is used to support the bracket 41. The support mechanism 3 includes a support block 32 fixedly connected to the upper surface of the base 1, and the support block 32 is rotatably connected to the support rod 31. One end of the support rod 31 is rotatably connected to the adapter block 33. The support rod 31 in the support block 32 on the base 1 rotates with the frequency at which the vibration plate 24 pushes the bracket 41 to shake. The support rod 31 rotates in the adapter block 33 and the support block 32, so as to support the shaking bracket 41;

[0029] The screening mechanism 4 is installed on the connecting block 25 and the adapter block 33. The screening mechanism 4 includes a bracket 41 installed on the upper surface of the support rod 31. The inner wall of the bracket 41 is fixedly connected to a plurality of support rods 43. The screening mechanism 4 includes a bracket 41 fixedly connected to four adapter blocks 33. The bracket 41 is fixedly connected to the connecting block 25. The inner wall of the bracket 41 is detachably mounted with a first screen 44, the inner wall of the bracket 41 is detachably mounted with a second screen 45, and the inner wall of the bracket 41 is detachably mounted with a collecting plate 46. The sieve holes of the first screen 44 and the second screen 45 are different in size. A discharge plate 47 is fixedly connected to the surfaces of the first screen 44, the second screen 45, and the collecting plate 46. A triangular plate 42 is fixedly connected to the surface of the bracket 41. When the bracket 41 is shaken, the corn kernels are screened by the first filter plate on the bracket 41. After the smaller corn kernels fall through the sieve holes of the first screen 44, the corn kernels that meet the standards remain in the first screen 44. The second screen 45 continues to screen the fallen corn kernels. The smaller corn kernels pass through the sieve holes of the second screen 45, pass through the guide frame 51 located between the second screen 45 and the collecting plate 46, and fall onto the collecting plate 46.

[0030] A guide mechanism 5 is installed on the bracket 41, which includes a guide frame 51 installed on the bracket 41, and the inner wall of the guide frame 51 is conical; a canvas cover 52 is fixedly connected to the lower surface of the guide frame 51; wherein: the guide frame 51 is suitable for corn kernels that are piled in a relatively middle position and fall, and under the cover of the canvas cover 52, accurately fall into the second screen 45 and the collection plate 46, and there are two groups of guide frames 51, which are distributed between the first screen 44 and the second screen 45, and between the second screen 45 and the collection plate 46. After the smaller corn kernels fall from the sieve holes on the first screen 44, they enter the guide frame 51 located between the first screen 44 and the second screen 45, and fall onto the second screen 45 along the canvas cover 52. The qualified corn kernels remain in the first screen 44, and the staff uses a collection bag to collect the sieved corn kernels at the discharge plate 47.

[0031] Working principle:

[0032] When the corn kernels need to be screened, the staff uses a conveyor to transport the corn kernels to the first screen 44 on the top layer of the bracket 41, and then starts the vibration motor 21 to drive the capstan 22 to rotate. While the capstan 22 rotates, it drives the vibration plate 24 to move along the rocker 23 on the capstan 22. The vibration plate 24 pushes the bracket 41 to shake, and the support rod 31 in the support block 32 on the base 1 rotates at the frequency at which the vibration plate 24 pushes the bracket 41 to shake. The support rod 31 rotates in the adapter block 33 and the support block 32 to support the shaking bracket 41.

[0033] When the bracket 41 is shaking, the corn kernels are screened by the first filter plate on the bracket 41. The smaller corn kernels fall through the sieve holes on the first screen 44 and enter the guide frame 51 located between the first screen 44 and the second screen 45. They fall along the canvas cover 52 and onto the second screen 45. The qualified corn kernels remain in the first screen 44. The staff uses a collection bag to collect the screened corn kernels at the discharge plate 47. The second screen 45 continues to screen the fallen corn kernels. The smaller corn kernels pass through the sieve holes of the second screen 45, pass through the guide frame 51 located between the second screen 45 and the collecting plate 46, and fall onto the collecting plate 46.

[0034] The above description is merely a preferred embodiment of the present application and is not intended to limit the present application. Various modifications and variations are possible for those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present application shall be included within the scope of protection of the present application.
