[0033] Reference Figure 1-3 A rice seed screening device comprises a bottom plate 1, a screening structure 2 is arranged on the bottom plate 1, and is used for screening rice seeds. The screening structure 2 comprises a bracket 201 installed on the bottom plate 1, a support rod 202 is installed on the bracket 201, one end of the support rod 202 is rotatably connected to a first rotating roller 203, a rotating rod 204 is installed at one end of the first rotating roller 203, a rotating plate 205 is installed at one end of the rotating rod 204, a placing box 206 is installed at both ends of the rotating plate 205, a supporting plate 212 is installed on each of the two placing boxes 206, and a first electric telescopic rod is installed on each of the two supporting plates 212. 207, the telescopic ends of the two first electric telescopic rods 207 are both equipped with mounting rods 208, and one end of the two mounting rods 208 is both equipped with baffles 209, and the two baffles 209 are used to block the discharge port of the corresponding placement box 206. The rice seeds that need to be screened are placed in one of the placement boxes 206, and then the placement box 206 is turned to a high place, and then the two first electric telescopic rods 207 are started, so that the telescopic ends drive the baffles 209 to move and no longer block the discharge port of the placement box 206, so that the rice seeds fall from a high place into the placement box 206 below.

[0034] A fan 3 is installed on the bottom plate 1. When the rice seeds fall, the fan 3 is started to blow away the mud, impurities, debris, shrunken grains, unripe or broken grains and other removed materials from the rice seeds with the help of wind. After the above-mentioned multiple inversions of the positions of the two placement boxes 206 and multiple air selections, the effect of screening the rice seeds is achieved.

[0035] A motor 213 is installed on the bottom plate 1, and a second roller 214 is installed at the output end of the motor 213. A transmission belt 215 is connected between the second roller 214 and the outer side of the first roller 203. By starting the motor 213, it drives the second roller 214 to rotate, and the rotation of the second roller 214 drives the transmission belt 215, thereby driving the rotation of the first roller 203, so as to facilitate the position adjustment of the two placement boxes 206.

[0036] Reference Figure 2 A slide groove 210 is provided on the placement box 206, and the placement box 206 is slidably connected to a slide rod 211 through the slide groove 210. The telescopic end of the first electric telescopic rod 207 is installed at one end of the slide rod 211, and the slide rod 211 is used to support the telescopic end of the first electric telescopic rod 207.

[0037] Reference Figure 3 and Figure 4 A material taking component 4 is provided on one of the placement boxes 206, and the material taking component 4 includes a material taking port 405 opened on one of the placement boxes 206, a connecting plate 402 installed on the placement box 206, and a cover plate 401 hinged on the placement box 206, a second electric telescopic rod 403 is installed on the connecting plate 402, and a squeezing plate 404 is installed at the telescopic end of the second electric telescopic rod 403. After the air selection is completed, the second electric telescopic rod 403 is started, so that the telescopic end drives the squeezing plate 404 to move, so that the squeezing plate 404 no longer squeezes the cover plate 401, and then the cover plate 401 rotates. At this time, the rice seeds are discharged through the material taking port 405.

[0038] Reference Figure 1 , Figure 2 as well as Figure 5 A dustproof structure 5 is provided on the side of the bottom plate 1 away from the fan 3. The dustproof structure 5 includes a collecting box 501 installed on the bottom plate 1. A U-shaped intercepting plate 502 is installed on the collecting box 501. A water pump 503 is installed on one side of the collecting box 501. A first water pipe 504 connected to the inside of the collecting box 501 is installed at the input end of the water pump 503. A second water pipe 505 is installed at the output end of the water pump 503. A horizontal pipe 506 is installed on the intercepting plate 502. One end of the second water pipe 505 is connected to the horizontal pipe 506. The interior of the pipe 506 is interconnected, and a filter screen 507 is installed on the collection box 501. When the removed objects are blown away from the rice seeds, the water pump 503 is started, so that the water in the collection box 501 enters the second water pipe 505 through the first water pipe 504, and is finally discharged through the horizontal pipe 506 to form a water curtain. At this time, the removed objects are blown by the wind and contact the water curtain and quickly fall down and are intercepted on the filter screen 507, thereby achieving the dust removal effect and avoiding as much as possible that a large amount of removed objects are in the air and affect the health of the operator.

[0039] Working principle:

[0040] The rice seed screening device places the rice seeds to be screened in one of the placement boxes 206, then rotates the placement box 206 to a higher position, and then starts two first electric telescopic rods 207, so that the telescopic ends of the rods drive the baffles 209 to move and no longer block the discharge port of the placement box 206, so that the rice seeds fall from a higher position into the placement box 206 below, and starts the fan 3 to blow away the sediment impurities, debris, shrunken grains, unripe or broken grains and other removed materials from the rice seeds with the help of wind force. After the above-mentioned multiple reversals of the positions of the two placement boxes 206 and multiple air selections, the effect of screening the rice seeds is achieved.

[0041] In the rice seed screening device, when the removed objects are blown away from the rice seeds, the water pump 503 is started, so that the water in the collection box 501 enters the second water pipe 505 through the first water pipe 504, and is finally discharged through the horizontal pipe 506 to form a water curtain. At this time, the removed objects are blown by the wind and contact the water curtain and quickly fall down and are intercepted on the filter net 507, thereby achieving the dust removal effect and avoiding as much as possible that a large amount of removed objects are in the air and affect the health of the operator.

[0042] After the winnowing is completed, the rice seed screening device starts the second electric telescopic rod 403 so that the telescopic end drives the squeezing plate 404 to move, so that the squeezing plate 404 no longer squeezes the cover plate 401, and then the cover plate 401 rotates. At this time, the rice seeds are discharged through the feeding port 405.

[0043] Although the preferred embodiments of the utility model have been described, those skilled in the art may make other changes and modifications to these embodiments once they have learned the basic creative concept. Therefore, the appended claims are intended to be interpreted as including the preferred embodiments and all changes and modifications falling within the scope of the utility model.

[0044] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
