[0024] The effect achieved by the entire embodiment 1 is that when the rice bran needs to be screened, the rice bran is first poured into the feed bin 4, and the rice bran in the feed bin 4 slides into the screening mechanism 2 through the guide plate 5. The screening mechanism 2 can screen the rice bran and can be shaken left and right to improve the screening efficiency of the rice bran. Shaking the screening mechanism 2 left and right can also prevent the screening mechanism 2 from being blocked. The dust suction mechanism 3 can process the dust generated during the rice bran screening, preventing the dust from affecting the quality of the rice bran, and also reducing the impact of dust diffusion in the environment.

[0025] Embodiment 2, as Figure 1-Figure 5As shown, the screening mechanism 2 includes a screening frame 201, and four slide bars 202 are fixedly installed on the outer wall of the screening frame 201, and one end of the outer wall of the four slide bars 202 passes through the outer wall of the processing box 1, and one end of the outer wall of the four slide bars 202 is slidably connected to the processing box 1. The outer walls of the four slide bars 202 are provided with springs 203, and one end of the four springs 203 is fixedly connected to the processing box 1, and the other end of the four springs 203 is fixedly connected to the screening frame 201. The top of the screening frame 201 is fixedly installed with a frame 204, and the outer wall of the frame 204 is fixedly installed with a motor 205, and the inner wall of the frame 204 is rotatably connected with a rotating shaft 206, and the outer wall of the rotating shaft 206 is fixedly installed with an eccentric block 207, and the output shaft of the motor 205 passes through the outer wall of the frame 204 and is fixedly connected to one end of the outer wall of the rotating shaft 206, and the bottom of the screening frame 201 is provided with a group of screening holes 208. The dust collecting mechanism 3 includes an exhaust fan 301 and a filter box 302. A filter device is arranged inside the filter box 302. The exhaust fan 301 and the filter box 302 are fixedly connected. The output end of the filter box 302 is fixedly connected with a connecting pipe 303. The output end of the connecting pipe 303 passes through the top of the processing box 1 and is fixedly connected with a dust collecting cover 304. A collection box 6 is movably inserted into the outer wall of the processing box 1. A handle 7 is fixedly installed on the outer wall of the collection box 6. Four shock-absorbing foot pads 8 are fixedly installed at the bottom of the processing box 1. The exhaust fan 301 and the filter box 302 are fixedly connected to the processing box 1.

[0026] The effect achieved by the entire embodiment 2 is that when the screening mechanism 2 needs to be used, in order to increase the filtering speed of the screening frame 201, the motor 205 can be turned on, and the motor 205 drives the eccentric block 207 to rotate. The eccentric block 207 will drive the screening frame 201 to swing left and right during the rotation. When the screening frame 201 swings, it will compress the extrusion spring 203, and the spring 203 can generate a certain elastic force on the screening frame 201, so that the screening frame 201 can swing left and right in the processing box 1.

[0027] Working principle: When the rice bran needs to be screened, the rice bran is first poured into the feed bin 4, and the rice bran in the feed bin 4 slides into the screening frame 201 through the guide plate 5. The screening frame 201 is provided with a screening hole 208 at the bottom, and the rice bran falls through the screening hole 208 and falls into the collecting box 6, while some solid particle impurities will be left in the screening frame 201. In order to increase the filtering speed of the screening frame 201, the motor 205 can be turned on, and the motor 205 drives the eccentric block 207 to rotate. The eccentric block 207 will drive the screening frame 201 to shake left and right during the rotation process. When the screening frame 201 shakes, it will compress the extrusion spring 203, and the spring 203 can generate a certain elastic force on the screening frame 201. Thereby, the screening frame 201 can be swung left and right in the processing box 1, thereby improving the screening efficiency of the screening frame 201 for rice bran. At the same time, swaying the screening frame 201 left and right can also prevent the screening hole 208 from being blocked. During the screening process of rice bran, there may be dust inside the processing box 1. At this time, the exhaust fan 301 can be turned on. The exhaust fan 301 extracts the dust inside the processing box 1 into the filter box 302 through the dust hood 304, so that the dust can be collected, preventing the dust from affecting the quality of the rice bran, and also reducing the impact of dust diffusion in the environment. When the rice bran screening is completed, the collection box 6 in the processing box 1 can be pulled out by pulling the handle 7, and the screened rice bran can be collected.
