[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0020] Reference Figures 1-4 A screening device for corn processing includes a housing 1, a feeding box 101 fixedly connected to the top of the housing 1, a control component 2 installed inside the feeding box 101 for evenly distributing corn into the housing 1, and a screening component 3 installed inside the housing 1 for screening the corn. The device also includes:
[0021] The control component 2 includes a mounting bracket 201, which is fixedly mounted on the side wall of the feed box 101. A first servo motor 202 is fixedly connected to the side wall of the mounting bracket 201. A threaded post 203 is fixedly connected to the output end of the first servo motor 202. A sliding block 204 is threadedly connected to the side wall of the threaded post 203. A feed pipe 205 is snapped onto the side wall of the sliding block 204, and the feed pipe 205 is located above the feed box 101.
[0022] A second servo motor 206 is fixedly connected to the side wall of the feed box 101. A first rotating shaft 207 is fixedly connected to the output end of the second servo motor 206. A rotating plate 208 is fixedly connected to the side wall of the first rotating shaft 207, and the rotating plate 208 can fit against the inner wall of the feed box 101.
[0023] It should be noted that: the first servo motor 202 drives the threaded column 203 to rotate. The threaded connection between the threaded column 203 and the sliding block 204 causes the sliding block 204 to drive the feed pipe 205 to slide back and forth on the top of the feed box 101, thereby evenly spreading the corn in the inner cavity of the feed box 101. The second servo motor 206 drives the first rotating shaft 207 to rotate. The first rotating shaft 207 drives the rotating plate 208 to rotate, so that the corn is poured into the inner cavity of the box 1 in an orderly manner for screening, avoiding excessive corn entering the inner cavity of the box 1 and causing excessive accumulation, making screening difficult.
[0024] Reference Figures 1-4 The screening component 3 includes a sieve plate 301, which is slidably installed on the inner wall of the box 1 and is inclined. A spring 302 is fixedly connected between the sieve plate 301 and the inner wall of the box 1.
[0025] A rotating column 303 is rotatably connected to the side wall of the box 1 below the sieve plate 301. An extrusion column 304 is fixedly connected to the side wall of the rotating column 303, and the extrusion column 304 can fit against the bottom of the sieve plate 301.
[0026] Both the rotating column 303 and the side wall of the first rotating shaft 207 are fixedly connected to sprockets 305, and the sprockets 305 are rotatably connected to each other by a track 306.
[0027] It should be noted that: when corn falls into the top of the sieve plate 301 in the inner cavity of the box 1, there is a track 306 between the first rotating shaft 207 and the sprocket 305 on the side wall of the rotating column 303, so that the first rotating shaft 207 drives the rotating column 303 to rotate, and the rotation of the rotating column 303 drives the squeezing column 304 to squeeze the sieve plate 301, which stretches the spring 302 and generates a rebound force, thereby causing the sieve plate 301 to vibrate, thereby enhancing the screening effect of the sieve plate 301.
[0028] Reference Figures 1-4 A bottom box 4 is fixedly connected to the side wall of the box 1, and a transmission bucket 401 is fixedly connected to the top of the bottom box 4. The transmission bucket 401 extends into the inner cavity of the bottom box 4, and the transmission bucket 401 is set in an inclined position.
[0029] A third servo motor 402 is fixedly connected to the top of the transmission barrel 401. A second rotating shaft 403 is fixedly connected to the output end of the third servo motor 402. A spiral blade 404 is fixedly connected to the side wall of the second rotating shaft 403.
[0030] The top of the side wall of the transfer barrel 401 is fixedly connected to the feed pipe 205, and the feed pipe 205 is made of elastic material. A dust removal device 405 is fixedly connected to the top of the box 1.
[0031] It should be noted that: the corn is placed in the inner cavity of the bottom box 4, and then the third servo motor 402 is driven. The third servo motor 402 drives the spiral blades 404 on the side wall of the second rotating shaft 403 to rotate, thereby conveying the corn in the inner cavity of the bottom box 4 to the top of the transfer bucket 401, and then orderly entering the inner cavity of the feed box 101 through the feed pipe 205. The dust removal device 405 can remove the dust generated during the corn screening process.
[0032] Operation method: Place the corn in the inner cavity of the bottom box 4, and then drive the third servo motor 402. The third servo motor 402 drives the spiral blade 404 on the side wall of the second rotating shaft 403 to rotate, thereby conveying the corn in the inner cavity of the bottom box 4 to the top of the transfer bucket 401, and then into the inner cavity of the feeding box 101 through the feeding pipe 205. At the same time, drive the first servo motor 202, which drives the threaded column 203 to rotate. Utilize the threaded connection between the threaded column 203 and the sliding block 204 to make the sliding block 204 drive the feeding pipe 205 to slide back and forth on the top of the feeding box 101, thereby evenly spreading the corn in the inner cavity of the feeding box 101.
[0033] The second servo motor 206 drives the first rotating shaft 207 to rotate, which in turn drives the rotating plate 208 to rotate, thus orderly pouring the corn into the surface of the sieve plate 301 inside the box 1. There is a track 306 between the first rotating shaft 207 and the sprocket 305 on the side wall of the rotating column 303, which causes the first rotating shaft 207 to drive the rotating column 303 to rotate. The rotation of the rotating column 303 drives the extrusion column 304 to extrude the sieve plate 301, which stretches the spring 302 and generates a rebound force, thereby causing the sieve plate 301 to vibrate, thereby enhancing the screening effect of the sieve plate 301.
