With the increase in my country's rice production and the continuous improvement of science and technology, my country's rice processing industry has also made great progress.

[0003] When processing rice, a common method is to select it by air. However, it is only screened by blowing air, because the larger impurities inside are difficult to be blown away by the wind, so the larger impurities inside are often difficult to remove. Therefore, a new type of air separator for rice processing is needed to solve the above problem. Summary of the invention

[0004] In order to achieve the above-mentioned purpose, the utility model specifically adopts the following technical solutions:

[0005] A wind separator for rice processing comprises: a mounting frame, an inner wall of the mounting frame is provided with a screening frame, and a vibration mechanism, the vibration mechanism is used to vibrate the screening frame, an air screening bin arranged above the screening frame is fixedly installed inside the mounting frame, and a fan is fixedly installed on the inner wall of the air screening bin.

[0006] Furthermore, the mounting frame includes a placing frame, a fixing frame is fixedly mounted on the top of the placing frame, the sub-screening frame is arranged inside the placing frame, and the wind screening bin is fixedly mounted on the inner wall of the fixing frame.

[0007] Furthermore, the sub-screening frame comprises a vibration frame, the inner wall of which is fixedly mounted with a first screen and a second screen, and two discharge ports are provided on both sides of the sub-screening frame.

[0008] Furthermore, the vibration mechanism includes a plurality of springs whose one ends are fixedly mounted on both sides of the inner wall of the placement rack, and the other ends of the plurality of springs are fixedly mounted on both sides of the inner wall of the vibration frame, and a vibration motor is fixedly mounted on the bottom of the vibration frame.

[0009] Furthermore, the inner walls of the two discharge ports are both inclined surfaces.

[0010] The beneficial effects of the utility model are as follows:

[0011] When the utility model is in use, the user turns on the fan and pours the rice into the inlet of the wind screen bin. The rice is sucked by the wind of the fan and the tiny impurities inside are sucked away. Then the rice enters the inside of the screening frame. Under the action of the vibration mechanism, the screening frame vibrates continuously and the rice inside is screened again to remove the large impurities inside. With this arrangement, larger impurities can also be removed, thereby improving the cleaning effect of the impurities and fully reflecting the practicality of the device.

[0017] In order to make the purpose, technical solution and advantages of the embodiments of the present utility model clearer, the technical solution in the embodiments of the present utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the present utility model.

[0018] The present application provides a wind separator for rice processing, which is mainly used to solve the problem that the common method of rice processing is to select the rice by wind, but the rice is only screened by blowing air, because the larger impurities inside the rice are difficult to be blown away by the wind, so the larger impurities inside the rice are often difficult to remove, and the following technical solutions are provided. Figure 1-Figure 4 Make a detailed description:

[0019] A wind separator for rice processing comprises: a mounting frame 1 placed on the ground, an inner wall of the mounting frame 1 is provided with a screening frame 2 for screening large impurities inside the rice, and also comprises a vibration mechanism 3 for vibrating the screening frame 2 so that the rice inside the screening frame is ejected from the rice outlet thereof, a wind screening bin 4 arranged above the screening frame 2 is fixedly installed inside the mounting frame 1, a fan 5 is fixedly installed on the inner wall of the wind screening bin 4, and the user pours the rice into the wind screening bin 4 from the feed inlet at the top of the wind screening bin 4, and the rice can be screened by the wind force of the fan 5, wherein the main components of the mounting frame 1 are: a placing frame 101, a fixing frame 102 is fixedly installed on the top of the placing frame 101, the screening frame 2 is arranged inside the placing frame 101, and the wind screening bin 4 is fixedly installed on the fixing frame 102 The inner wall of the screening frame 2 is mainly composed of: the screening frame 2 includes a vibration frame 201, the inner wall of the vibration frame 201 is fixedly installed with a first screen 202 and a second screen 203, the sieve holes on the surfaces of the first screen 202 and the second screen 203 have different diameters, which are used to screen impurities of different sizes, and two discharge ports 204 for discharging impurities and rice are provided on both sides of the screening frame 2, wherein the main components of the vibration mechanism 3 are: a plurality of springs 301, one end of which is respectively fixedly installed on both sides of the inner wall of the placement rack 101, and the other ends of the plurality of springs 301 are respectively fixedly installed on both sides of the inner wall of the vibration frame 201, and the user can drive the vibration frame 201 to vibrate by controlling the vibration motor 302 fixedly installed at the bottom of the vibration frame 201.
