Abstract
Description
Technical Field
[0001] The present application relates to the technical field of rice processing, and in particular to a feeding device for a rice polishing machine. Background Art
[0002] During the rice processing process, the raw rice needs to go through multiple processes, including removing impurities, removing rice husks, removing bran, grading, polishing, color sorting, etc., to finally make rice. At present, when processing rice through a polishing machine, most of the rice is directly placed in the hopper for centralized feeding. However, since the rice is easily blocked when it is piled up in one place, it is necessary to stir the rice manually during the processing process, which reduces the processing efficiency of the rice. In addition, there is a lack of effective filtration of impurities in the rice. Since some soil or stone particles are easily mixed in the rice when it is harvested and dried, if the impurities are processed with the rice, it will greatly affect the purity of the rice.

DETAILED DESCRIPTION
[0017] The following is combined with Figure 1-3 This application is described in further detail.
[0018] The present application embodiment discloses a feeding device for a rice polishing machine. Figure 1 , including a base 1, on which a screening hopper 2 is provided, and a vibration motor 9 is installed at the bottom of the screening hopper 2. The vibration motor 9 will generate a certain excitation force when it is working, and it will resonate with the screening hopper 2 at this time. Since reinforcement blocks 7 are welded at the corners of the outer wall of the screening hopper 2, a support spring 8 is provided at the bottom of the reinforcement block 7, and the two ends of the support spring 8 are respectively connected to the base 1 and the inner wall of the reinforcement block 7. Through the elastic expansion and contraction force of the support spring 8, the screening hopper 2 can be driven to produce fluctuations of corresponding amplitudes, thereby promoting the screening of internal rice.
[0019] like Figure 2 As shown, a screening plate 13 is installed in the middle of the screening hopper 2, and the screening hopper 2 and the screening plate 13 are both arranged to be inclined toward one side. A separation partition 12 is detachably provided on the screening plate 13, and a screen 14 and a screen 2 15 are respectively provided on the screening plate 13 from one side to the other side. The apertures of the screen 14 and the screen 2 15 are arranged to allow rice to pass through, and the aperture of the screen 14 is slightly smaller than that of the screen 2 15. The separation partition 12 is used to separate impurities between the screen 14 and the screen 2 15 to facilitate careful filtering of the rice.
[0020] Screening cavities 10 are provided at both ends of the screening plate 13. The upper screening cavity 10 is used to intercept larger stone impurities in the rice, and the bottom screening cavity 10 is used to collect the rice. A card slot 11 is symmetrically opened in the middle of the inner wall of the screening hopper 2. The card slot 11 is adapted to the separation partition 12. A handle 3 is fixedly connected to the top of the separation partition 12. The separation partition 12 is detachable for easy manual operation.
[0021] Combination Figure 3 As shown, a feed box 4 is fixedly provided on the outer wall at one end of the screening hopper 2, and a group of feed ports 16 are opened on the inner wall of the feed box 4 near one end of the screening hopper 2, and a diverter plate 17 is fixedly provided on the inner wall of the feed box 4. The diverter plate 17 is installed diagonally in the feed box 4 to divert rice and impurities, and a feed pipe 5 is provided inside one side of the feed box 4, and the rice is discharged from the feed pipe 5. A feed pipe 2 6 is provided on the side of the feed box 4 away from the feed pipe 5, and the sieved impurities are discharged through the feed pipe 2 6 for subsequent treatment.
[0022] The implementation principle of the feeding device of a rice polisher according to the embodiment of the present application is as follows: when in use, the rice to be processed is placed in the screening hopper 2, and the vibration motor 9 is started at the same time. The vibration motor 9 drives the screening hopper 2 to resonate. Due to the elasticity of the support spring 8, the rice inside is promoted to be initially screened through the screen 14 on the surface of the screening plate 13. At this time, the separation partition 12 is limited in the card slot 11, and the screen 14 can filter impurities whose volume is larger than the rice. Then, the separation partition 12 is lifted upward by the handle 3, and the screened part of the rice and impurities are further filtered out. The rice is then filtered through the screen 15. Since the aperture of the screen 15 is slightly larger than that of the screen 14, it can promote the screening of rice and further filter out large impurities. After screening, the rice is discharged downward into the screening cavity 10, and is synchronously diverted to one side with the impurities in the upper screening cavity 10, and is introduced into the feed box 4 through the feed port 16. At this time, the impurities will be discharged outward through the feed pipe 2 6 along the inclination angle of the diverter plate 17, while the rice is discharged outward through the feed pipe 1 5, and the feed pipe 1 5 and the feed port of the rice polisher are connected by a hose, so as to facilitate subsequent processing.
