[0003] In existing technologies, rice drum separators typically place rice directly into a drum with sieve holes to separate small grains while retaining larger ones. However, traditional drum separators have fixed sieve hole sizes, limiting their ability to filter only one type of rice grain. Furthermore, the drums themselves cannot be replaced, resulting in low practicality and inconvenience in actual use. Utility Model Content

[0004] The purpose of this invention is to provide a rice sorting machine that solves the problem that traditional drum sorting machines have fixed sieve hole sizes, which means they can only sort out rice grains of one type and size. The drums cannot be replaced, resulting in low practicality and inconvenience in actual use.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0027] Reference Figure 1-6A rice selection machine includes a base 2, a connecting box 1 on the surface of the base 2, and casters 3 at the bottom of the base 2. The side wall of the connecting box 1 is open, and a sieve cylinder 19 is installed inside the connecting box 1. A motor 10 for driving the sieve cylinder 19 to rotate is fixedly installed at the end of the connecting box 1. The bottom wall of the connecting box 1 is sloped, and a discharge port is opened at the lower part of the slope. A support mechanism is provided between the connecting box 1 and the base 2. Two fixing rings 12 are fixedly installed inside the connecting box 1, and the sieve cylinder 19 is detachably inserted into the two fixing rings 12. A transmission rod 11 is fixedly installed at the output shaft port of the motor 10. The port of the transmission rod 11 is configured with a cross shape. A cross-shaped groove is opened at the end of the connecting box 1 away from the motor 10. A limiting mechanism is provided at the end of the connecting box 1 away from the motor 10 to prevent the sieve cylinder 19 from moving out. In use, the sieve cylinder 19 is installed on the connecting box 1. Inside box 1, rice is poured into the sieve cylinder 19. The sieve cylinder 19 is then restricted by a limiting mechanism. The motor 10 is started, and the motor 10 drives the transmission rod 11 to rotate. The transmission rod 11 engages with the cross-shaped groove at the end of the sieve cylinder 19 using its own cross-shaped structure, thereby driving the sieve cylinder 19 to rotate within the fixed ring 12. During the rotation, the rice can be carefully selected. The non-compliant rice grains that are screened off fall directly into the connecting box 1 and slide out from the discharge port using the inclined surface. After screening, the entire connecting box 1 and sieve cylinder 19 are tilted using a support mechanism, making it easy to pour out the remaining rice. Depending on different selection needs, the sieve cylinder 19 can be replaced. In specific operation, the limiting mechanism is released, and then the sieve cylinder 19 is pulled out from the fixed ring 12. Finally, a sieve cylinder 19 with different aperture sizes can be replaced for easy operation.

[0028] Furthermore, a rotating ring 13 is rotatably connected inside the fixed ring 12, and the screen cylinder 19 is inserted inside the rotating ring 13. The diameter of the screen cylinder 19 is matched with the inner diameter of the rotating ring 13. By setting the rotating ring 13, the rotational friction between the screen cylinder 19 and the fixed ring 12 can be reduced, and the smoothness of rotation can be improved.

[0029] Furthermore, the limiting mechanism includes a connecting rod 14, which is slidably inserted into the end of the connecting box 1. A screw 17 rotatably passes through the surface of the connecting rod 14, and the screw 17 is threadedly connected to the connecting box 1. A slide rod 15 is slidably connected to the bottom end of the connecting rod 14. In use, after the screen cylinder 19 is installed, the slide rod 15 slides downward. Then, the screw 17 is rotated, which drives the entire connecting rod 14 to move inward, thereby causing the slide rod 15 to move synchronously. The slide rod 15 then contacts the screen cylinder 19, preventing the screen cylinder 19 from sliding out due to the restriction of the slide rod 15. When it is necessary to remove the screen cylinder 19, the screw 17 is first rotated to move the connecting rod 14 outward, thereby causing the connecting rod 14 to move the slide rod 15 outward. Then, the slide rod 15 is moved upward so that it no longer obstructs the screen cylinder 19.

[0030] Furthermore, the slide bar 15 has an "L" shaped structure, and a steel ball 16 is movably connected to the end of the slide bar 15. An annular groove 18 is opened at the end of the screen cylinder 19, and the steel ball 16 is embedded in the inside of the annular groove 18. By setting the steel ball 16 to contact the annular groove 18, the screen cylinder 19 will not directly rub against the slide bar 15 when it rotates, making it more convenient to use.

[0031] Furthermore, the support mechanism includes four support legs 4. A fixing rod 5 is fixedly installed on the surface of the base 2. A rotating shaft 6 rotatably passes through the surface of the fixing rod 5. Two support legs 4 are fixedly passed through both ends of the rotating shaft 6. A first connecting block 7 is rotatably connected to the surface of the base 2. A hydraulic cylinder 8 is fixedly installed on the surface of the first connecting block 7. A second connecting block 9 is fixedly installed at the output end of the hydraulic cylinder 8. The second connecting block 9 and the connecting box 1 are rotatably connected. In use, when it is necessary to tilt the connecting box 1 and the sieve cylinder 19 to pour out rice, the hydraulic cylinder 8 is directly activated. The hydraulic cylinder 8 will cause the entire connecting box 1 to rotate around the rotating shaft 6, thereby tilting it. During normal screening, the support legs 4 are used for support to keep the connecting box 1 and the sieve cylinder 19 horizontal.

[0032] Furthermore, the end of the sieve cylinder 19 away from the motor 10 is set as an opening, and the opening is set as a conical structure. By setting the opening at the end of the sieve cylinder 19 as a conical structure, it is convenient for the rice inside to be poured out. The rice is also fed through this opening. The opening is located in the center position, so no rice will flow out from the opening when rotating.

[0033] In summary, during use, the sieve cylinder 19 is installed inside the connecting box 1. Rice is poured into the sieve cylinder 19, and then the sieve cylinder 19 is restrained by the limiting mechanism. The motor 10 is started, and the motor 10 drives the transmission rod 11 to rotate. The transmission rod 11 uses its own "+" shaped structure to engage with the "+" shaped groove at the end of the sieve cylinder 19, thereby driving the sieve cylinder 19 to rotate within the fixed ring 12. During the rotation, the rice can be carefully selected. The non-compliant rice grains that are sieved fall directly into the connecting box 1 and slide out from the discharge port using the inclined surface. After screening, the entire rice is held in place by the support mechanism. The connecting box 1 and the sieve cylinder 19 are tilted to facilitate pouring out the remaining rice. The sieve cylinder 19 can be replaced according to different selection needs. In specific operation, simply release the limiting mechanism and then pull the sieve cylinder 19 out of the fixing ring 12. Finally, replace it with a sieve cylinder 19 with a different aperture size for convenient operation. The rotating ring 13 reduces the rotational friction between the sieve cylinder 19 and the fixing ring 12, improving the smoothness of rotation. In use, after installing the sieve cylinder 19, slide the slide rod 15 downwards, then rotate the screw 17. The screw 17 will drive... The entire connecting rod 14 is moved inward, thereby driving the sliding rod 15 to move synchronously. The sliding rod 15 then contacts the screen cylinder 19, preventing the screen cylinder 19 from sliding out. When it is necessary to remove the screen cylinder 19, first rotate the screw 17 to move the connecting rod 14 outward, causing the connecting rod 14 to drive the sliding rod 15 outward. Then, move the sliding rod 15 upward so that it no longer obstructs the screen cylinder 19. By setting the steel ball 16 to contact the annular groove 18, the screen cylinder 19 will not directly rub against the sliding rod 15 when rotating, making it easier to remove. In use, when it is necessary to tilt the connecting box 1 and the screen cylinder 19 to facilitate the pouring out of rice, the hydraulic cylinder 8 is directly activated. The hydraulic cylinder 8 will cause the entire connecting box 1 to rotate around the rotating shaft 6, thereby making it tilted. During normal screening, the support legs 4 are used for support to keep the connecting box 1 and the screen cylinder 19 horizontal. By setting the opening at the end of the screen cylinder 19 to a conical structure, it is convenient for the rice inside to be poured out. The rice is also fed through this opening. The opening is located in the center position, so no rice will flow out from the opening when rotating.
