In addition to being edible, rice can also be used as industrial raw materials for brewing and sugar making, and rice husks and rice stalks can be used as livestock feed. The main rice producing areas in China are mainly the Yangtze River Basin, the Pearl River Basin, and the Northeast. Before rice is milled into rice and then stored, it is often necessary to use automatic screening devices to screen the rice, so as to facilitate the subsequent detection of rice quality.

[0028] There are multiple groups of air outlets 206, and the multiple groups of air outlets 206 are distributed at equal intervals;

[0029] Specifically, Figure 1 , Figure 3 , Figure 4 and Figure 5 As shown, when in use, the blower 202 is started to blow the generated wind into the interior of the screening box 1 through the blowing port 206 under the cooperation of the exhaust pipe 201 and the fixed pipe 203, so that the rice husk mixed with the rice is blown into the interior of the discharge port 8 by the wind force and discharged through the discharge port 8, so that the staff can collect the rice husk for subsequent processing;

[0030] A collecting frame 6 is provided inside the screening box 1, and guide blocks 5 are fixed on both sides of the collecting frame 6;

[0031] The guide block 5 slides inside the guide groove 7, and the collection frame 6 is slidably connected to the screening box 1 through the guide block 5 and the guide groove 7;

[0032] Specifically, Figure 1 , Figure 4 As shown, when in use, the guide block 5 slides inside the collecting frame 6, so that the staff can take out the unqualified rice collected inside the guide groove 7 to avoid excessive accumulation inside the guide groove 7, which affects subsequent operations;

[0033] The outer sides of the guide blocks 5 are all provided with guide grooves 7, and the guide grooves 7 are all opened inside the screening box 1, and the screening mechanism 4 is arranged inside the screening box 1;

[0034] The screening mechanism 4 includes a screening motor 405, and the screening motor 405 is arranged at the top of the screening box 1, and the bottom end of the screening motor 405 is rotatably connected with a driving shaft 406, and the outer side of the driving shaft 406 is sleeved with a push plate 404, and the outer side of the bottom end of the driving shaft 406 is sleeved with a driving bevel gear 407, and both sides of the driving bevel gear 407 are meshed with driven bevel gears 408, and both sides of the driving bevel gear 407 and the driven bevel gear 408 are fixed with limiting blocks 409, and the interior of the driven bevel gear 408 is penetrated by a driven shaft 402, and the outer side of the driven shaft 402 is sleeved with a cam 401, and one side of the cam 401 is provided with a convex block 403, and the convex block 403 is fixed to the bottom end of the sieve plate 3;

[0035] There are two cams 401 and two protrusions 403, which are symmetrically distributed and made of rubber.

[0036] There are three groups of limit blocks 409, each group of limit blocks 409 has two limit blocks, and the cross-sections of the three groups of limit blocks 409 are all annular;

[0037] A protective frame 10 is sleeved on the outer side of the bottom end of the screening mechanism 4, and a screen plate 3 is arranged inside the screening box 1 at the top end of the collecting frame 6;

[0038] Specifically, Figure 1 , Figure 2 and Figure 3As shown, when in use, the screening motor 405 is started to drive the driving shaft 406 to rotate, which, on the one hand, drives the push plate 404 to push the rice dropped on the sieve plate 3, thereby increasing the contact area between the rice and the sieve plate 3, thereby improving the screening efficiency. On the other hand, the driven shaft 402 is driven to rotate under the action of the active bevel gear 407 and the driven bevel gear 408, so that the cam 401 hits the protrusion 403, and then the sieve plate 3 vibrates, thereby achieving the purpose of automatic screening of the rice.

[0039] Working principle: When the utility model is used, first, when it is necessary to inspect the quality of rice, the rice to be inspected is introduced into the interior of the screening box 1 through the guide port 9. During the introduction process, the blower 202 is started, and the outside air is sucked into the interior of the blower 202 under the action of the exhaust pipe 201, and is transported to the interior of the air guide pipe 204 through the fixed pipe 203, and is discharged through the blowing port 206 with the cooperation of the connecting pipe 205, thereby generating wind force inside the screening box 1, so that the rice entering the screening box 1 is under the action of the wind force, so that the qualified rice falls on the screen plate 3 under the influence of its own weight, and the unqualified rice husk is blown into the interior of the discharge port 8 by the wind force and discharged through the discharge port 8. The rice husk mixed in the rice is screened through the above operation, thereby improving its practicality.

[0040] Then, the screening motor 405 is started to drive the driving shaft 406 to rotate, and the driving shaft 406 drives the push plate 404 to rotate synchronously while the push plate 404 rotates to push the rice dropped on the sieve plate 3 to rotate synchronously. The above operation can not only increase the contact area between the rice and the sieve plate 3 and improve the screening efficiency, but also flatten the rice accumulated on the sieve plate 3 to avoid the rice from accumulating on the sieve plate 3, and the push plate 404 rotates while the driving bevel gear 407 drives the driven bevel gear 408 to rotate synchronously. Since the driving bevel gear 407 and the driven bevel gear 408 are meshed with each other, the driving bevel gear 407 drives the driven bevel gear 408 to rotate while the driven bevel gear 408 is meshed with each other. 08 performs synchronous rotational motion, and by setting a limit block 409, the active bevel gear 407 and the driven bevel gear 408 that move for a long time can be limited to avoid positional deviation during the long-term movement, thereby affecting subsequent operations. While the driven bevel gear 408 performs rotational motion, it drives the driven shaft 402 to perform synchronous rotational motion, thereby driving the cam 401 to hit the protrusion 403, and then the sieve plate 3 vibrates, and the rice on the sieve plate 3 is screened by the vibration of the sieve plate 3, so that the sub-qualified rice falls into the inside of the collecting frame 6 for collection, and the qualified rice remains on the sieve plate 3, and the qualified rice is taken out through the box door 11. The rice is screened and inspected by the above operation, thereby improving the screening effect.
