Description

Technical Field

[0001] This utility model relates to the field of rice processing technology, specifically to a rice and brown rice separator. Background Technology

[0002] Brown rice refers to whole grain rice that has been hulled and is not processed or minimally processed, retaining the bran, germ, and endosperm. Compared to refined rice, brown rice retains more nutrients, such as dietary fiber, vitamins, and minerals, and has higher nutritional value.

[0003] Existing rice-brown rice separators typically separate rice by shaking and sieving. However, after two separations, a small amount of brown rice remains in the rice, requiring a second sieving. This repeated feeding increases the workload for workers, and the inability to adjust the discharge port diameter makes it unsuitable for containers of different sizes. Therefore, further improvements are needed. Utility Model Content

[0004] To address the aforementioned problems, this utility model provides the following technical solution: a paddy rice and brown rice separator, comprising a frame, with a first and second sieve platform mounted on the top of the frame via a support, the first sieve platform being located above the second sieve platform. A feed inlet is located on the top of the first sieve platform, and a second feed inlet is located on the top of the second sieve platform, both located below the discharge outlet of the first sieve platform. A brown rice discharge outlet is located at the bottom of the second sieve platform, with a secondary sieve discharge outlet in the middle. A primary conveyor is located on the top of the frame and directly below the secondary sieve discharge outlet. A secondary conveyor is located on the top of the frame and below the other end of the primary conveyor. A tertiary conveyor is located on the top of the frame on one side relative to the primary conveyor, with one bottom end of the tertiary conveyor located below the top of the secondary conveyor and one top end of the tertiary conveyor located above the first feed inlet.

[0005] As an optimization, auxiliary positioning components for stabilizing the machine are provided on both sides of the bottom of the frame. The auxiliary positioning components include supports fixedly installed at the bottom of the frame, a fixed cylinder fixedly installed inside the supports, a lifting screw screw screwed inside the fixed cylinder, a pad block rotatably connected to the bottom of the lifting screw screw, and a rotating part fixedly installed on the outer side of the lifting screw screw.

[0006] As an optimization, a rubber pad is twisted and bonded to the bottom side of the pad, and the bottom side of the rubber pad is provided with friction texture.

[0007] As an optimization, the rotating part has outwardly extending support plates on both sides, and the two rotating parts are staggered vertically.

[0008] As an optimization, an adjustment component for adjusting the size of the discharge port is provided at the outlet of the brown rice discharge port. The adjustment component includes side frames fixedly installed on both sides of the brown rice discharge port. A bearing is provided in the middle of the side frame. A bidirectional screw is rotatably connected inside the bearing. Slide plates are spirally sleeved on the outer sides of both ends of the bidirectional screw. A guide plate is fixedly installed on the opposite side of the two slide plates. A knob is fixedly installed on both ends of the bidirectional screw.

[0009] As an optimization, the slide plate is slidably inserted into the inside of both sides of the brown rice outlet, and the guide plate and the slide plate are set perpendicularly.

[0010] As an optimization, the knob is fitted with a rubber sleeve on its outer side.

[0011] The beneficial effects of this utility model are:

[0012] 1. This paddy rice separator uses a first-layer and a second-layer screen to screen paddy rice in sequence. After two screenings, the paddy rice is discharged from the paddy rice outlet. The paddy rice that needs to be screened again falls onto the first-layer conveyor through the second-layer and third-layer conveyors and is then transported upwards to the first-layer inlet for screening again, thus reducing the labor intensity of workers.

[0013] 2. This rice and brown rice separator, by turning the knob, will drive the bidirectional screw to rotate inside the slide plate, which will in turn drive the slide plates on both sides to move relative to each other. Therefore, it will cause the guide plates on both sides to move closer or further apart, so that the inner diameter of the discharge port can be adjusted according to the actual container diameter, thus improving its applicability.

[0014] 3. This rice and brown rice separator, by turning the rotating part, will drive the lifting screw to rotate inside the fixed cylinder, which will in turn drive the pad to move downward until it touches the ground, thus positioning and supporting the machine, thereby improving the stability of the machine.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1The rice and brown rice separator includes a frame 1. A first-layer screen 2 and a second-layer screen 3 are mounted on the top of the frame 1 via supports, with the first-layer screen 2 located above the second-layer screen 3. A feed inlet 4 is located on the top of the first-layer screen 2, and a second-layer feed inlet 5 is located on the top of the second-layer screen 3, below the discharge outlet of the first-layer screen 2. A brown rice discharge outlet 6 is located at the bottom of the second-layer screen 3, with a secondary screening outlet 7 in the middle of the outlet 6. A primary conveyor 8 is mounted on the top of the frame 1, directly below the secondary screening outlet 7. A secondary conveyor 9 is mounted on the top of the frame 1, below the other end of the primary conveyor 8. A [missing information - likely a conduit or structure] is mounted on the top side of the frame 1 opposite the primary conveyor 8. The three-stage conveyor 10 has its bottom end located below the top of the two-stage conveyor 9 and its top end located above the first-stage feed inlet 4. By starting the machine, the first-stage screen 2 shakes to screen the internal paddy rice. The screened paddy rice falls into the second-stage screen 3 through the second-stage feed inlet 5. After being screened by the second-stage screen 3, the qualified paddy rice is discharged out through the paddy rice outlet 6, while the unqualified paddy rice falls onto the first-stage conveyor 8 through the re-screening outlet 7. Then, it is conveyed upward through the second-stage conveyor 9 and the three-stage conveyor 10 to the first-stage feed inlet 4, where it can be screened again, reducing the labor intensity of workers.

[0022] Please see Figure 2 The bottom sides of the frame 1 are provided with auxiliary positioning components for stabilizing the machine. The auxiliary positioning components include a support 11 fixedly installed at the bottom of the frame 1. A fixed cylinder 12 is fixedly installed inside the support 11. A lifting screw 13 is screwed into the fixed cylinder 12. A pad 14 is rotatably connected to the bottom of the lifting screw 13. A rubber pad is twisted and bonded to the bottom side of the pad 14, and the bottom side of the rubber pad has friction texture. A rotating part 15 is fixedly installed on the outside of the lifting screw 13. The rotating part 15 has outwardly extending support plates on both sides, and the two rotating parts 15 are staggered vertically. By turning the rotating part 15, the lifting screw 13 will rotate inside the fixed cylinder 12, which will drive the pad 14 to move downward until it touches the ground. At this time, it can serve as a support to improve the stability of the machine.

[0023] Please see Figure 3An adjustment component for adjusting the size of the discharge port is provided at the outlet of the brown rice discharge port 6. The adjustment component includes side frames 16 fixedly installed on both sides of the brown rice discharge port 6. A bearing 17 is provided in the middle of the side frame 16. A bidirectional screw 18 is rotatably connected inside the bearing 17. Slide plates 19 are spirally sleeved on the outer sides of both ends of the bidirectional screw 18. The slide plates 19 are slidably inserted into the inner sides of the brown rice discharge port 6. A guide plate 20 is fixedly installed on the opposite side of the two slide plates 19, and the guide plate 20 and the slide plate 19 are set perpendicularly. A knob 21 is fixedly installed on both ends of the bidirectional screw 18. A rubber sleeve is provided on the outer side of the knob 21. By turning the knob 21, the bidirectional screw 18 will rotate inside the slide plate 19, which will cause the two slide plates 19 to move relative to each other. Therefore, the guide plates 20 on both sides will move closer or further apart, so that the inner diameter of the discharge port can be adjusted according to the actual container diameter, thereby improving applicability.

[0024] When in use, firstly, turning the rotating part 15 will drive the lifting screw 13 to rotate inside the fixed cylinder 12, which will then drive the pad block 14 to move downwards until it touches the ground. At this point, it can serve as a support to improve the stability of the machine. Then, start the machine, which will cause the first-layer screen table 2 to shake and screen the internal paddy rice. After screening, the paddy rice will fall into the second-layer screen table 3 along the second-layer feed inlet 5. After being screened by the second-layer screen table 3, the qualified paddy rice will be discharged outwards along the paddy rice outlet 6, while the unqualified paddy rice will fall onto the first-level conveyor 8 along the re-screening outlet 7. Then, it will be conveyed upwards through the second-level conveyor 9 and the third-level conveyor 10 to the first-layer feed inlet 4, where it can be screened again, reducing the labor intensity of workers.

[0025] At the same time, turning the knob 21 will drive the bidirectional screw 18 to rotate inside the slide plate 19, which will in turn drive the slide plates 19 on both sides to move relative to each other. This will cause the guide plates 20 on both sides to move closer or further apart, thereby adjusting the inner diameter of the discharge port according to the actual container diameter and improving applicability.

[0026] In summary, this paddy rice separator uses a first-layer screen 2 and a second-layer screen 3 to screen paddy rice in sequence. After two screenings, the brown rice is discharged through the brown rice outlet 6. The paddy rice that needs to be screened again falls through the rescreening outlet 7 onto the primary conveyor 8, and then passes through the secondary conveyor 9 and the tertiary conveyor 10 to be transported upward to the first-layer inlet 4, where it can be screened again, thus reducing the labor intensity of workers.

[0027] Turning the knob 21 will cause the bidirectional screw 18 to rotate inside the slide plate 19, which will in turn cause the slide plates 19 on both sides to move relative to each other. This will cause the guide plates 20 on both sides to move closer or further apart, thereby adjusting the inner diameter of the discharge port according to the actual container diameter and improving applicability.

[0028] By turning the rotating part 15, the lifting screw 13 will rotate inside the fixed cylinder 12, which will in turn drive the pad 14 to move downward until it touches the ground. At this point, the machine can be positioned and supported, thereby improving the stability of the machine.
