[0003] When rice is rubbed and processed, some rice husks will adhere to the surface of the rice. Generally, blowing is used to screen the rice and rice husks. Since the blowing mechanism is fixedly installed inside the screening box, and the particle weight of the rice is not fixed, it causes personnel to be unable to adjust the distance between the blowing and the rice inlet according to needs, so that the blowing force on the rice cannot be adjusted according to needs, and thus the rice and rice husks with different particle sizes cannot be screened, which will affect the applicability of the device to a certain extent.

[0023] The technical solution of the present utility model will be further elaborated in detail below in conjunction with the accompanying drawings of the specification and specific embodiments.

[0024] Embodiment 1:

[0025] A rice processing grading and screening device provided by the present application includes a screening box 1; a feed inlet 101 is provided at the top of the screening box 1, and adjusting mechanisms 3 are symmetrically arranged on both sides of the inner cavity of the screening box 1, and a blowing mechanism 4 is arranged on the surface of the adjusting mechanism 3;

[0026] The adjusting mechanism 3 includes a chute 301, an electric slide rail 302 and a slider 303. The chutes 301 are symmetrically opened on the front and rear sides of the inner wall of the screening box 1. The electric slide rail 302 is fixedly installed inside the chute 301. The slider 303 is slidably installed on the surface of the electric slide rail 302. The peeling mechanism 2 includes a silica gel roller 201 and a motor 202. The silica gel roller 201 is rotatably installed in the inner cavity of the screening box 1. The motor 202 is arranged outside the screening box 1 and fixedly connected to one end of the motor 202. The blowing mechanism 4 includes an installation groove 401, a wind groove 402 and a fan 403. The installation groove 401 is opened in the inner cavity of the slider 303. The wind grooves 402 are equidistantly opened on one side of the slider 303. The fans 403 are equidistantly installed in the inner cavity of the installation groove 401;

[0027] Specifically, such as Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, when the device is screening rice, at this time, the operator adds the rice into the inner cavity of the screening box 1 through the feeding port 101, and then drives the silica gel rollers 201 to rotate in the inner cavity of the screening box 1 by two groups of motors 202. The rice is kneaded by the two groups of silica gel rollers 201, so that the rice can be quickly separated from the rice husks. At this time, the operator can turn on the electric slide rail 302 through the external controller, and drive the blowing mechanism 4 to slide in the inner cavity of the screening box 1 through the slider 303 to adjust the distance between the blowing mechanism 4 and the rice falling from the bottom of the motor 202. The operator can turn on the fan 403 through the external controller, and the wind generated by the rotation of the fan 403 is blown out through the wind groove 402, so that the kneaded rice and rice husks can be quickly separated. Then the rice will fall to the bottom of the screening box 1 through the partition plate 5 under its own gravity, and the rice husks will be blown out under the action of the blowing force, so that the rice and rice husks can be quickly screened. During the use of the device, the blowing mechanism 4 can be driven to slide inside the screening box 1 through the adjusting mechanism 3, and the distance of the rice falling port between the blowing mechanism 4 and the silica gel roller 201 can be adjusted according to the size of the rice grains, so that the blowing force of the blowing mechanism 4 on the rice can be quickly adjusted. Therefore, the device can not only meet the screening of different amounts of rice grains, but also further improve the applicability of the device during the screening process of rice grains.

[0028] Furthermore, peeling mechanisms 2 are symmetrically arranged in the inner cavity of the screening box 1, a partition plate 5 is fixedly installed at the bottom of the screening box 1, an inclined plate 6 is arranged at the bottom of the screening box 1, a discharge port 10 is opened on one side of the screening box 1, a sealing cover 1001 is snap-fitted on the surface of the discharge port 10, a blanking port 7 is opened at the bottom of the screening box 1, a valve 701 is installed on the surface of the blanking port 7, and a mounting frame 8 is installed below the blanking port 7 at the bottom of the screening box 1, and a conveyor belt 9 is installed inside the mounting frame 8;

[0029] Specifically, as Figure 1 、 Figure 2 shown, when the rice is separated from the rice husks by the blowing mechanism 4 inside the screening box 1, the rice will fall into the inner cavity of the screening box 1 after passing through the inclined partition plate 5 under the action of gravity, and the rice husks will be blown to the other side inside the inner cavity of the screening box 1. When the screening of the rice by the device is completed, at this time, the operator can open the valve 701 through the external controller, then the screened rice at the bottom of the screening box 1 will fall above the conveyor belt 9 through the blanking port 7, and the rice will be conveyed by the conveyor belt 9 into the internal color sorter for multi-stage screening. At the same time, the operator can separate the sealing cover 1001 from the discharge port 10, and then discharge the screened rice husks inside the screening box 1 through the discharge port 10 for use.

[0030] Working principle: Rice is added into the inner cavity of the screening box 1 through the feeding port 101, and then two groups of motors 202 drive the silica gel rollers 201 to rotate in the inner cavity of the screening box 1. The two groups of silica gel rollers 201 knead the rice, so that the rice can be quickly separated from the rice husks. At this time, the operator can turn on the electric slide rail 302 through the external controller, and drive the blowing mechanism 4 to slide in the inner cavity of the screening box 1 through the slider 303 to adjust the distance between the blowing mechanism 4 and the rice falling from the bottom of the motor 202. The operator can turn on the fan 403 through the external controller, and the wind generated by the rotation of the fan 403 is blown outwards through the wind groove 402, so that the rice and the rice husks after kneading can be quickly separated. Then the rice will fall to the bottom of the screening box 1 through the partition plate 5 under the action of its own gravity, and the rice husks will be blown outwards under the action of the blowing force, so that the rice and the rice husks can be quickly screened.

[0031] Finally, it should be noted that the above specific embodiments are only used to illustrate the technical solutions of the present invention and not to limit them. Although the present invention has been described in detail with reference to the embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified and equivalently replaced without departing from the spirit and scope of the technical solutions of the present invention, and they should all be covered within the scope of the claims of the present invention.
