Description

Technical Field

[0001] This utility model relates to the field of rice polishing technology, specifically a rice polishing machine for rice processing. Background Technology

[0002] Rice polishing is a key process that balances appearance quality and nutrient retention. Its technological development trend has shifted from "pursuing the ultimate whiteness" to "moderate processing, green and efficient".

[0003] For example, a rice polishing machine for rice processing, with announcement number "CN216826343U", uses a first, second, and third polishing rod. Because the third, fourth, and fifth gears are all meshed, the first, second, and third polishing rods rotate simultaneously, allowing them to polish the rice concurrently. This speeds up the polishing process, meets the device's operational requirements, and improves its practicality, making it worthy of promotion. However, when the three polishing rods rotate, the rice at the lower end cannot contact the rods and accumulates, preventing it from being polished. Furthermore, the polished rice is not filtered, leaving impurities unfiltered and requiring further filtration by the operator. Utility Model Content

[0004] The purpose of this invention is to solve the problems of the above-mentioned equipment, where the rice at the bottom cannot contact the polishing rods when the three polishing rods rotate, and thus accumulates at the bottom, making it impossible to polish the rice. At the same time, the above-mentioned equipment does not filter the polished rice, and the impurities generated after polishing cannot be filtered out, requiring workers to filter it again. Therefore, this invention proposes a rice polishing machine for rice processing.

[0005] To achieve the above objectives, this utility model provides the following technical solution: Design a rice polishing machine for rice processing, including a base plate, a polishing cylinder fixedly connected to the upper left side of the base plate, a cylinder cover installed at the upper end of the polishing cylinder, a polishing mechanism provided above the cylinder cover, a bending plate fixedly connected to the upper end of the cylinder cover, a vibration motor installed at the lower end of the polishing cylinder, and a filtering mechanism provided on the right side of the polishing cylinder.

[0006] Preferably, the filtration mechanism includes a first motor, the output shaft of the first motor is fixedly connected to an auger, the outer wall of the auger is in contact with the cylinder and the filter screen, the filter screen is mounted on the cylinder, and a support frame is fixedly connected to the upper end of the cylinder.

[0007] Preferably, the outer wall of the support frame is threadedly connected to the first motor by bolts, and the outer wall of the cylinder is fixedly connected to the polishing cylinder.

[0008] Preferably, the polishing mechanism includes a second motor and an electric telescopic rod. The output shaft of the second motor is fixedly connected to a rotating rod. The outer wall of the rotating rod is slidably connected to a slide rod. The upper part of the outer wall of the slide rod is rotatably connected to a rotating plate through a bearing.

[0009] Preferably, the outer walls of the rotating plate are fixedly connected to the output ends of the electric telescopic rod on both sides, and multiple polishing rollers are fixedly connected to the outer walls of the sliding rod.

[0010] Preferably, the outer walls of the electric telescopic rods are all fixedly connected to the bending plates, and the outer wall of the second motor is threadedly connected to the cylinder cover by bolts.

[0011] The rice polishing machine for rice processing proposed in this utility model has the following advantages: Through the cooperation of the polishing mechanism and the polishing cylinder, the output shaft of the second motor rotates to drive the rotating rod to rotate, the rotating rod rotates to drive the sliding rod to rotate, the sliding rod rotates to drive the polishing roller to rotate, and the polishing roller polishes the rice. Activating two electric telescopic rods causes the output ends of the electric telescopic rods to extend and retract, driving the rotating plate to move. The protrusion of the rotating plate is limited by the cylinder cover and moves linearly. The movement of the rotating plate drives the sliding rod to move, and the movement of the sliding rod drives the polishing roller to move, polishing the rice. The reciprocating movement of the electric telescopic rods drives the polishing roller to move up and down. By polishing the rice through the up-and-down movement of the polishing roller, polishing dead angles are reduced, thus ensuring that most of the rice can be polished.

[0012] With the cooperation of the filtration mechanism and the vibration motor, the first motor is started. The output shaft of the first motor rotates, which drives the auger to rotate. The rotation of the auger drives the rice to move to the right. The rice moves to the right and passes through the filter screen, filtering out the impurities produced during the polishing of the rice. After that, the filtered rice is discharged from the right side of the cylinder. The staff uses two collection boxes to collect the impurities and rice respectively. The polished rice can be filtered without the need for manual filtration by the staff. Attached Figure Description

A curved plate 7 is fixedly connected to the upper end of the cylinder cover 5, and a vibration motor 3 is installed at the lower end of the polishing cylinder 4. When the vibration motor 3 is started, the polishing cylinder 4 vibrates, causing the rice to move to the right along the slope of the inner wall of the polishing cylinder 4. A filter mechanism 2 is provided on the right side of the polishing cylinder 4.

[0016] See attached document Figure 1-2 And 4: The filter mechanism 2 includes a first motor 201, and the output shaft of the first motor 201 is fixedly connected to an auger 202. The rotation of the output shaft of the first motor 201 drives the auger 202 to rotate. The outer wall of the auger 202 is in contact with the cylinder 205 and the filter screen 204. The rotation of the auger 202 drives the rice to move inside the cylinder 205. The filter screen 204 is installed on the cylinder 205. The filter screen 204 is a detachable filter screen that can filter impurities. The upper end of the cylinder 205 is fixedly connected to the support frame 203. The outer wall of the support frame 203 is threadedly connected to the first motor 201 by bolts. The outer wall of the cylinder 205 is fixedly connected to the polishing cylinder 4.

[0017] See attached document Figure 1-3 And 5: The polishing mechanism 6 includes a second motor 601 and an electric telescopic rod 602. The electric telescopic rod 602 is a self-locking electric telescopic rod 602. The output shaft of the second motor 601 is fixedly connected to a rotating rod 603. The rotation of the output shaft of the second motor 601 drives the rotating rod 603 to rotate. The outer wall of the rotating rod 603 is slidably connected to a slide rod 604. The slide rod 604 slides along the outer wall of the rotating rod 603. The protrusion of the slide rod 604 engages with the groove of the rotating rod 604. The rotation of the slide rod 604 drives the rotating rod 604 to rotate. The upper part of the outer wall of the slide rod 604 is rotatably connected to the rotating plate 605 through a bearing. The movement of the rotating plate 605 drives the slide rod 604 to move. The two sides of the outer wall of the rotating plate 605 are fixedly connected to the output end of the electric telescopic rod 602. The extension and retraction of the output end of the electric telescopic rod 602 drives the rotating plate 605 to move. Multiple polishing rollers 606 are fixedly connected to the outer wall of the slide rod 604. The rotation of the slide rod 604 drives the polishing rollers 606 to rotate. The outer wall of the electric telescopic rod 602 is fixedly connected to the bending plate 7. The outer wall of the second motor 601 is threadedly connected to the cylinder cover 5 with bolts.

[0018] Working principle: When polishing rice.

[0019] Work process: The staff conveys rice through the feed pipe of the cover 5 into the polishing cylinder 4 via the conveying mechanism. The second motor 601 is then started. The output shaft of the second motor 601 rotates, driving the rotating rod 603 to rotate. The rotating rod 603 then drives the sliding rod 604 to rotate, which in turn drives the polishing roller 606 to rotate. The polishing roller 606 polishes the rice. Two electric telescopic rods 602 are then activated. Through PLC programming control, the two electric telescopic rods 602 start synchronously. The output ends of the electric telescopic rods 602 extend and retract, moving the rotating plate 605. The protrusion of the rotating plate 605 is limited by the cover 5, causing linear motion. The movement of the rotating plate 605 moves the sliding rod 604, which in turn moves the polishing roller 606, polishing the rice. The reciprocating movement of the electric telescopic rods 602 causes the polishing roller 606 to move up and down, reducing polishing dead angles. After polishing is completed, the second motor 601 and the electric telescopic rod 602 are stopped (both are controlled by a PLC controller). The staff places the collection box under the right opening of the filter screen 204 and the cylinder 205 for collection. The vibration motor 3 is started, which causes the polishing cylinder 4 to vibrate, thus causing the rice to move to the right along the slope of the polishing cylinder 4. The first motor 201 is started, and the output shaft of the first motor 201 rotates, driving the auger 202 to rotate. The rotation of the auger 202 causes the rice to move to the right. The rice moves to the right and is filtered by the filter screen 204, which filters out the impurities generated during rice polishing (impurities include rice husk fragments, rice bran, broken rice, dust, and other foreign objects). The filtered rice is then discharged from the right side of the cylinder 205. The staff uses two collection boxes to collect the impurities and rice respectively. After completion, the rice polishing is achieved.
