Description

Technical Field

[0001] This utility model relates to the field of rice testing technology, specifically to a rice polishing degree testing device. Background Technology

[0002] Rice (paddy rice) is a food made from paddy rice through processes such as cleaning, hulling, milling, and finishing. Rice is a staple food for people in most parts of China. After paddy rice is hulled, it becomes brown rice. Brown rice, after removing most of the bran and part of the germ, becomes the rice we eat. However, the surface of the rice grains still has a small amount of bran powder, which affects the appearance and quality of the rice and the taste of the cooked rice. Therefore, it is often necessary to remove this bran powder through a polishing process.

[0003] Under current technological conditions, evaluating the polishing effect of rice usually requires the use of specialized testing equipment to determine its polishing degree. However, in existing technologies, before placing the polished rice into the testing equipment, the rice grain sample must first be flattened. This step is currently mostly done manually. This manual flattening method is not only inefficient, but also prone to affecting the accuracy and repeatability of subsequent test results due to uneven spreading or inconsistent pressure. In addition, manual operation increases the time cost of the testing process, limits the improvement of testing throughput, and is not conducive to rapid and continuous quality monitoring on the production line.

[0015] (III) Beneficial Effects

[0016] Compared with the prior art, this utility model provides a rice polishing degree testing device, which has the following beneficial effects:

[0017] (1) In this utility model, polished rice is placed in a placement frame, the second motor is started, and the second helical gear is driven to rotate, which in turn drives the first helical gear fixed on the rotating rod to rotate synchronously. The rotation of the rotating rod causes the cam installed on it to act accordingly, periodically pushing the support frame to produce a horizontal displacement in the support platform. The movement of the support frame is transmitted to the placement frame, causing it to move up and down in the support platform, thereby enhancing the vibration effect of the placement frame. This vibration process can automatically spread the rice in the placement frame evenly, effectively replacing the traditional manual spreading operation. After spreading is completed, the polishing degree of the rice grain surface is detected by a photometer installed at the bottom of the moving block. The whole process realizes the automated and continuous operation from spreading to detection, improves the detection efficiency and result consistency, and overcomes the problems of low efficiency and uneven spreading caused by manual operation.

[0018] (2) After the test is completed, the operator can pull the handle at the top of the placement frame upward. At this time, the first magnet fixed at the bottom of the placement frame will disengage from the magnetic attraction between the second magnet on both sides of the bottom upper surface of the support frame. At the same time, the limiting blocks on both sides of the placement frame will also disengage from the corresponding limiting grooves of the support frame. Through this continuous operation, the placement frame can be smoothly removed from the support frame, so as to conveniently remove the rice that has been tested. This avoids the problem of cumbersome disassembly in the traditional structure and improves the ease of operation and practicality of the equipment. Attached Figure Description

The components in the figures are not drawn to scale, and similar component symbols are usually used to represent similar components.

[0027] According to an embodiment of the present invention, a rice polishing degree testing device is provided.

[0028] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments, such as... Figure 1-4As shown, a rice polishing degree testing device according to an embodiment of the present invention includes a support platform 1. Shaft seats are fixedly installed on both sides of the inner wall of the support platform 1, and a rotating rod 17 is fixedly installed between the shaft seats. The shaft seats ensure the normal rotation of the rotating rod 17, thereby driving the cam 25 on the rotating rod 17 to rotate. The cam 25 is fixedly installed on the rotating rod 17. A support frame 11 is provided in the support platform 1, and a placement frame 18 is provided in the support frame 11. An installation groove is opened in the support platform 1, and a second motor 16 is fixedly installed in the installation groove. A second helical gear 13 is fixedly connected to the output end of the second motor 16. The second helical gear 13 meshes with a first helical gear 12 fixedly installed on the rotating rod 17. The number of teeth of the first helical gear 12 corresponds to the number of teeth of the second helical gear 13, ensuring its normal rotation. Support columns 8 are fixedly connected to both sides of the top surface of the support platform 1, and a horizontal plate 2 is fixedly connected to the top of the support column 8. Electric push rods 3 are fixedly installed on both sides of the bottom surface of plate 2, and the output end of the electric push rods 3 is fixedly connected to a connecting frame 4. A mounting plate is fixedly connected to one side of the lower top surface of the connecting frame 4, and a first motor 7 is fixedly installed on one side of the mounting plate. A screw 9 is fixedly connected to the output end of the first motor 7, and a moving block 5 is threaded onto the screw 9. A photometer 10 is fixedly installed on the bottom surface of the moving block 5. The electric push rods 3 drive the connecting frame 4 to move, which can adjust the height of the photometer 10. After adjustment, the polishing degree of rice can be detected by using the photometer 10 on the bottom surface of the moving block 5. By starting the first motor 7, the first motor 7 drives the screw 9 to rotate. The moving block 5 is limited by the limiting rod 6, which allows it to move on the screw 9, thereby moving the photometer 10. The position of the photometer 10 can be adjusted, which helps to improve its working efficiency.

[0029] Please see Figure 2 and Figure 4 Handles 26 are fixedly connected to both sides of the top surface of the placement frame 18, and first magnet blocks 19 are fixedly connected to both sides of the bottom surface of the placement frame 18. The first magnet blocks 19 and the second magnet blocks 24 fixedly installed on both sides of the bottom upper surface of the support frame 11 attract each other. Pulling the handles 26 on the top surface of the placement frame 18 will cause the first magnet blocks 19 on the bottom surface of the placement frame 18 to move away from the second magnet blocks 24 on both sides of the bottom upper surface of the support frame 11. When the limiting blocks 20 on both sides of the placement frame 18 move away from the limiting grooves 21 on the support frame 11, the placement frame 18 can be taken out of the support frame 11, which makes it convenient to take out the tested rice and improves its practicality.

[0030] Please see Figure 2 and Figure 4Limiting blocks 20 are fixedly connected at the middle position of both sides of the placement frame 18, and one end of the limiting block 20 extends into the interior of the limiting groove 21 opened on both sides of the inner wall of the support frame 11. The limiting block 20 and the limiting groove 21 are slidably connected. The top end of the limiting groove 21 penetrates the top surface of the support frame 11. The use of the limiting block 20 and the limiting groove 21 can limit the placement frame 18, thereby maintaining the stability of the placement frame 18 in the support frame 11.

[0031] Please see Figure 1 and Figure 2 Gears 23 are fixedly installed on both sides of the support frame 11. Fixing grooves are opened on both sides of the inner wall of the support platform 1, and racks 22 are fixedly connected in the fixing grooves. Gears 23 mesh with racks 22. When the support frame 11 moves, gears 23 move on racks 22. Through the use of gears 23 and racks 22, the support frame 11 can be limited, thereby maintaining the stability of the support frame 11 during the movement.

[0032] Please see Figure 1 and Figure 2 The bottom upper surface of the support platform 1 has grooves 15 on both sides directly below the cam 25. The grooves 15 match the cam 25. The use of the grooves 15 can maintain the normal rotation of the cam 25 on the rotating rod 17.

[0033] Please see Figure 1 and Figure 3 Support legs 14 are fixedly connected to both sides of the bottom surface of the support platform 1. There are multiple support legs 14, and the multiple support legs 14 are evenly distributed in pairs on both sides of the bottom surface of the support platform 1. The support legs 14 support the support platform 1 and maintain the stability of the support platform 1 during use.

[0034] Please see Figure 1 and Figure 2 A limiting rod 6 is provided through the moving block 5 in the connecting frame 4. The moving block 5 is slidably connected to the limiting rod 6. The limiting rod 6 can limit the moving block 5, thereby maintaining the normal movement of the moving block 5 on the screw 9.

[0035] Please see Figure 3 The control switch control circuit can be implemented by simple programming by those skilled in the art. It is common knowledge in the field. We will only use it and not modify it. Therefore, the control method and circuit connection will not be described in detail.

[0036] Working principle: First, the polished rice is placed in the placement frame 18. The second motor 16 is started, which drives the second helical gear 13 to rotate. Simultaneously, the second helical gear 13 drives the first helical gear 12 on the rotating rod 17 to rotate, causing the cam 25 on the rotating rod 17 to rotate. As the cam 25 rotates, it pushes the support frame 11 to move on the support platform 1. This movement of the support frame 11, in turn, moves the placement frame 18, allowing it to reciprocate up and down on the support platform 1. This increases the vibration of the placement frame 18, thus automatically placing the rice... After the rice is flattened in the placement frame 18, the polishing degree of the rice can be detected by using the photometer 10 on the bottom surface of the moving block 5, which helps to improve its work efficiency. After the detection is completed, the handle 26 on the top surface of the placement frame 18 is pulled, so that the first magnet block 19 on the bottom surface of the placement frame 18 moves away from the second magnet blocks 24 on both sides of the bottom upper surface of the support frame 11. When the limiting blocks 20 on both sides of the placement frame 18 move away from the limiting grooves 21 on the support frame 11, the placement frame 18 can be removed from the support frame 11, which makes it easier to take out the tested rice and improves its practicality.
