[0011] Figure 1 It is a schematic diagram of the overall structure of the present utility model. Detailed Embodiment
[0012] The following further describes the present utility model in conjunction with all the drawings. The preferred embodiment of the present utility model is as follows. Refer to the attached Figure 1 In this embodiment, a broken rice collection and sorting device for a rice milling machine includes a sorting box 1. Among them, a broken rice inlet is provided at the top of the sorting box 1, and a connecting hopper 2 is connected to the sorting box 1 above the broken rice inlet. A first guide plate 3 is inclined and fixed in the upper cavity of the sorting box 1. A first throwing plate 4 is inclinedly installed on the surface of the first guide plate 3. The first throwing plates 4 are multiple and are inclinedly distributed on the first guide plate 3. The inclination angle of the first throwing plate 4 is smaller than that of the first guide plate 3. The higher end of the first guide plate 3 is located below the broken rice inlet, and the lower end of the first guide plate 3 is suspended. A sorting opening is reserved between the suspended end and the inner cavity wall of the sorting box 1. A second guide plate 5 is inclinedly installed in the sorting box 1 below the sorting opening. The higher end of the second guide plate 5 is located below the sorting opening, and a broken rice outlet is provided on the sorting box 1 at the lower end of the second guide plate 5.
[0013] The second deflector 5 is obliquely installed with a second spreading plate 6. There are multiple second spreading plates 6, which are obliquely distributed on the second deflector 5. The inclination angle of the second spreading plate 6 is smaller than that of the second deflector 5. A rice bran sorting area is reserved between adjacent second spreading plates 6. The second deflector 5 in the rice bran sorting area is provided with rice bran screening holes 8 penetrating up and down. A dust suction component is installed on the sorting box 1 at the sorting port. A rice bran deflector 7 is obliquely installed in the sorting box 1 below the second deflector 5. The higher end of the rice bran deflector 7 is located below the lower end of the second deflector 5. A rice bran outlet is provided on the sorting box 1 at the lower end of the rice bran deflector 7. The dust suction component includes a dust suction fan 9 and a dust discharge pipe 10. Among them, the sorting box 1 above the sorting port is provided with a dust suction port penetrating inside and outside. The dust suction fan 9 is installed at the dust suction port. The suction port of the dust suction fan 9 faces the direction of the first deflector 3. A dust discharge pipe 10 is connected to the outlet of the dust suction fan 9.
[0014] After adopting the above scheme, connect the connecting hopper to the broken rice outlet of the rice mill. The broken rice generated during rice milling enters the sorting box through the connecting hopper and falls onto the first deflector. When being conveyed along the inclined direction of the first deflector, under the guiding action of the first spreading plate, the broken rice will form a throwing (falling) downward conveyance. Under the action of throwing, the rice dust adhering to the broken rice is separated, and at the same time, the rice bran and the broken rice are further dispersed. The separated rice dust is sucked out by the dust suction fan and discharged uniformly through the dust discharge pipe (the outlet of the dust discharge pipe is connected to a cloth bag for dust collection). The dispersed rice bran and broken rice fall onto the second deflector and are conveyed downward under the inclination of the second deflector. During the conveyance process, a throwing effect is formed again through the second spreading plate. When throwing for the second time, the broken rice and the rice bran fall into the rice bran sorting area at the same time. The rice bran is screened through the rice bran screening holes in the rice bran sorting area. The screened rice bran falls onto the rice bran deflector and is discharged through the rice bran deflector; the screened broken rice is conveyed through the second deflector and discharged through the broken rice outlet. After adopting this scheme, the rice dust, rice bran and broken rice can be sorted. The utility model adopts a physical separation method, with low energy consumption, reasonable structure and good use effect.
