[0016] The specific embodiments of the present application will be further described below in combination with the drawings; the following embodiments are used to illustrate the present application, but not to limit the scope of the present application. And the described embodiments are part of the embodiments of the present disclosure, not all the embodiments. Based on the described embodiments of the present disclosure, all other embodiments obtained by those skilled in the art without creative labor are within the scope of protection of the present disclosure.

[0018] Please refer to Figures 1-4 A filter device for rice flour production, a filter bin 3 is connected to the upper end of the feed hopper 2 of the rice flour machine 1 by welding, a feed inlet 4 is formed in the upper end of the filter bin 3, the feed inlet 4 is located on the front side of the filter bin 3, the feed inlet is located on the rear side of the filter bin 3, a rectangular filter screen plate 7 is arranged below the feed inlet 4, which is used to filter out impurities in broken rice, the filter screen plate 7 as a whole is inclined downward along the horizontal plane rear end, and the rear end of the filter screen plate 7 and the inner wall of the filter bin 3 are spaced apart, so that the broken rice can enter from the feed inlet 4 and then slide into the feed hopper 2 through the filter screen plate 7.

[0019] Please refer to Figure 4 The lower end of each corner of the filter screen plate 7 is provided with a spring 8, which is connected to the filter bin 3 through the spring 8, one end of the spring 8 is connected to the filter screen plate 7 by welding, and the other end is connected to the filter bin 3 by welding. A drive motor 9 is fixedly installed in the filter bin 3, a cam 10 is fixedly arranged on the output shaft of the drive motor 9 by welding, the cam 10 is in contact with the filter screen plate 7, and the filter screen plate 7 will vibrate up and down with the rotation of the cam 10, which can not only more effectively screen out impurities in broken rice, but also prevent broken rice from being stuck on the filter screen plate 7. An upwardly open collecting box 11 is placed below the filter screen plate 7, which is used to collect the impurities falling after being screened by the filter screen plate 7.

[0020] Please refer to Figure 4In one embodiment, the inner wall of the filter bin 3 above the filter screen plate 7 is also inclined downwardly along the horizontal plane at the rear end, and the inclination angle is the same as that of the filter screen plate 7, and the spacing between the filter screen plate 7 and the filter bin 3 is 10-15 cm. In this way, when the broken rice passes through the filter screen plate 7, the broken rice is bounced back to the filter screen plate 7 after hitting the inner wall of the filter bin 3, so as to avoid a large amount of broken rice carrying impurities directly flying to the rear end and falling into the feeding hopper 2 under the vibration of the filter screen plate 7.

[0021] Please refer to Figure 4 In one embodiment, the inclination angle (the angle between the horizontal plane) of the filter screen plate 7 is 15-20°. In this way, the structure is more reasonable, because if the inclination angle is too large, the broken rice is easy to quickly slide through the filter screen plate 7 and fall into the feeding hopper 2, resulting in incomplete removal of the impurities carried; and if the inclination angle is too small, it is too flat, and the broken rice is not easy to move backward, which is easy to cause a blockage.

[0022] Please refer to Figure 4 In one embodiment, the rotation shaft of the cam 10 is parallel to the arrangement direction of the filter screen plate 7, and the arrangement direction (the central shaft) of the spring 8 is perpendicular to the filter screen plate 7. In this way, the structure is more reasonable.

[0023] Please refer to Figure 1 In one embodiment, a hinged cover plate 5 is arranged on the side wall of the filter bin 3 beside the collection box 11, and the rotation shaft is in the vertical direction. The cover plate 5 is opened and closed on the side wall of the filter bin 3 by rotating, and is used to take and place the collection box 11 at the cover plate 5. Further, a latch structure 6 is arranged on the side wall of the filter bin 3 and the cover plate 5 to fix the cover plate 5 after the cover plate 5 is closed. The specific structure of the latch structure 6 is a prior art, which will not be described in detail here. In this way, the collection box 11 can be easily taken out to clean the collected impurities.
