Specific Embodiments

[0028] To make the objectives, technical solutions, and advantages of the embodiments of the present utility model clearer, the following will, in conjunction with the accompanying drawings in the embodiments of the present utility model, clearly and completely describe the technical solutions in the embodiments. The following embodiments are used to illustrate the present utility model.

[0029] A rice bran and powder removing device, as Figure 1 , Figure 3 and Figure 4 shown, includes a support frame 10, the support frame 10 is fixedly placed on the ground, and a fixed cylinder 12 is fixedly arranged above the support frame 10; a powder removing assembly, the powder removing assembly is rotatably arranged in the fixed cylinder 12, the powder removing assembly includes a friction roller 21, a powder screening cylinder 22, and a feeding paddle 23, the powder screening cylinder 22 is rotatably arranged in the fixed cylinder 12, and both the friction roller 21 and the feeding paddle 23 are rotatably arranged in the powder screening cylinder 22; a driving assembly, the driving assembly is rotatably arranged on one side of the powder screening cylinder 22, the driving assembly includes a toothed ring 18, a driven gear 20, and a main gear 24, the toothed ring 18 is fixedly arranged on one side of the powder screening cylinder 22, both the driven gear 20 and the main gear 24 are transmission arranged in the toothed ring 18, and both the driven gear 20 and the main gear 24 are rotatably arranged on one side of the powder screening cylinder 22.

[0030] The working principle is as follows. By setting the driving assembly and cooperating with the powder removing assembly, the main gear 24 meshes with the driven gear 20 to rotate, the driven gear 20 will drive the toothed ring 18 to rotate, thereby driving the powder screening cylinder 22 to rotate. Synchronously, the feeding paddle 23 connected to the main gear 24 stirs the rice, making it contact the friction roller 21 driven by the driven gear 20. Then, the rice is rubbed between the inner wall of the powder screening cylinder 22 and the friction roller 21, so as to filter out the bran powder. Due to the rotation of the powder screening cylinder 22, the gap between the friction roller 21 and the inner wall of the powder screening cylinder 22 can be continuously changed, thereby reducing the dead angle of stirring and rubbing, and further ensuring the thoroughness of powder removal.

[0031] As Figure 1 shown, the support frame 10 is composed of a square plate and a U-shaped plate. Two supports 11 are fixedly arranged on the top surface of the square plate, and arc surfaces are provided on the top surfaces of the two supports 11. The fixed cylinder 12 is fixedly connected above the arc surfaces; as Figure 1 , Figure 2 and Figure 4 shown, a frustum-shaped rotating cavity 26 is provided inside the fixed cylinder 12. An L-shaped feeding pipe 16 is fixedly connected inside the fixed cylinder 12. The powder screening cylinder 22 is a hollow frustum-shaped cylinder body. The powder screening cylinder 22 is rotatably connected in the rotating cavity 26. A frustum-shaped baffle is arranged on the inner side of the powder screening cylinder 22 close to the feeding pipe 16. One end of the feeding pipe 16 close to the powder screening cylinder 22 is arranged in a funnel-shaped structure. The frustum-shaped baffle is similar to the funnel-shaped structure. The powder screening cylinder 22 is rotatably connected to the feeding pipe 16 through the frustum-shaped baffle; as Figure 3 , Figure 4 and Figure 5As shown in the figure, a screening cavity 28 is provided inside the powder screening cylinder 22. An arc-shaped discharge port is provided on one side of the powder screening cylinder 22 away from the tooth ring 18. The arc-shaped discharge port communicates with the screening cavity 28. A blocking block 25 is clamped at the arc-shaped discharge port. Four slave gears 20 mesh and drive the same main gear 24 and the same tooth ring 18. Four friction rollers 21 and the material stirring paddle 23 both rotate inside the screening cavity 28.

[0032] The working principle is as follows. The shape of the feed pipe 16 consists of an L-shaped pipe and a funnel-shaped pipe. The shape of the powder screening cylinder 22 is a U-shaped frustum cylinder. The concave part on the outside of the powder screening cylinder 22 is set as a frustum-shaped baffle similar to the shape of the funnel-shaped pipe of 16. By setting the frustum-shaped baffle, the stability between the powder screening cylinder 22, the feed pipe 16, and the fixed cylinder 12 can be ensured, so as to ensure the stable rotation of the powder screening cylinder 22 in the rotating cavity 26. At the same time, the hollow design of the powder screening cylinder 22 can help filter out fine bran powder and avoid rice being filtered out through the screening cylinder 22. By setting the powder screening cylinder 22, the bran powder and rice are separated using the shape of the powder screening cylinder 22. At the same time, the driving assembly is used in combination for rotational friction. After the powder screening cylinder 22 finishes rotating, the rice stays at the bottom position. When ensuring that the arc-shaped discharge port is in the lower position, the blocking block 25 can be removed to collect the rice.

[0033] As Figure 2 、 Figure 3 and Figure 4 shown, a circular ring groove is provided on one side of the powder screening cylinder 22 close to the U-shaped plate. A disc 29 is rotatably connected inside the circular ring groove. A driving hole 14 and four fixing holes 15 are provided in both the disc 29 and the U-shaped plate. A rotating shaft 27 is rotatably connected inside the driving hole 14 through a bearing. Different shaft columns 19 are rotatably connected inside the four fixing holes 15 through corresponding bearings. A placing plate 13 is fixedly connected to the side of the U-shaped plate away from the square plate. A motor 17 is fixedly arranged on the top surface of the placing plate 13. The output end of the motor 17 is connected to one end of the rotating shaft 27; as Figure 4 shown, a slave gear 20 is fixedly connected to the curved surface of each of the four shaft columns 19. The slave gear 20 is located outside the powder screening cylinder 22. A friction roller 21 is fixedly connected to the curved surface of each of the four shaft columns 19. The friction roller 21 is located inside the powder screening cylinder 22; as Figure 3 and Figure 4 shown, a material stirring paddle 23 is fixedly connected to the curved surface of the rotating shaft 27. The material stirring paddle 23 is located inside the powder screening cylinder 22. A main gear 24 is fixedly connected to the curved surface of the rotating shaft 27. The main gear 24 is located between the motor 17 and the material stirring paddle 23. The material stirring paddle 23 is located at the center of the four friction rollers 21. The main gear 24 is located at the center of the four slave gears 20.

[0034] The specific implementation is as follows. Start the motor 17, and the motor 17 drives the rotation of the main gear 24. The main gear 24 meshes with four slave gears 20 to rotate synchronously. Since the support frame 10 supports the positions of the four slave gears 20, the four slave gears 20 fix the position of the disk 29 by means of their respective corresponding shaft columns 19. When the four slave gears 20 are rotating, the toothed ring 18 rotates around the four slave gears 20 in mesh. At this time, the screening cylinder 22 rotates around the disk 29 driven by the toothed ring 18. Synchronously, the feeding paddle 23 connected to the main gear 24 rotates and stirs the rice raw materials. The friction roller 21 connected to the slave gear 20 presses the rice between itself and the inner wall of the powder screening cylinder 22. Due to the self-rotation of the friction roller 21 and the revolution of the powder screening cylinder 22, the rice is squeezed and rubbed between the two. During the process, the bran powder rubbed off passes through the powder screening cylinder 22 and is filtered out, while the rice remains in the screening cavity 28. After the powder removal is completed, stop the motor 17 when the arc-shaped discharge port is located at the lower end of the powder screening cylinder 22, remove the blocking block 25 used for blocking, and then the rice can be taken out.

As is known to those skilled in the art, without departing from the spirit and scope of the present utility model, various changes or equivalent replacements can be made to these features and embodiments. Additionally, under the teaching of the present utility model, these features and embodiments can be modified to adapt to specific situations and materials without departing from the spirit and scope of the present utility model.
