Description

Technical Field

[0001] This utility model relates to the field of rice milling machine technology, and in particular to a rice milling sieve for a rice milling machine. Background Technology

[0002] my country is a major grain-producing country, with a huge output of rice. When processing paddy into rice, rice milling machines are often used. The rice milling sieve is an important structure in the rice milling machine. Existing rice milling sieves are generally partially blocked by other fixed components, which increases the broken rice rate and reduces the quality of rice.

[0003] Prior art CN209020442U discloses a rice milling sieve for a rice milling machine, including two semi-cylindrical sieve plates, four splicing platforms, a rice sieve fixing assembly, guide rails, and multiple sliders. The four splicing platforms are respectively fixedly connected to the connection points of the two semi-cylindrical sieve plates. The rice sieve fixing assembly is disposed on the surface of the two semi-cylindrical sieve plates and includes two fixing beams, two connecting flanges, and multiple clamps. The two fixing beams are respectively fixedly connected to the four splicing platforms, the two connecting flanges are respectively fixedly connected to both ends of the two semi-cylindrical sieve plates, and the multiple clamps are fixedly connected to the surface of the two semi-cylindrical sieve plates. The guide rail is fixedly connected to the bottom of the fixed beam. Multiple sliders are slidably connected to the guide rail and are respectively set below multiple clamps. When installing the rice milling sieve, two semi-cylindrical sieve plates are spliced ​​together so that the four splicing surfaces are in contact with each other. The two semi-cylindrical sieve plates are then clamped together by cooperating with the two fixed beams. The multiple sliders are moved so that the multiple clamps are located between the multiple sieve holes on the two semi-cylindrical sieve plates, so that the sieve holes are not blocked. Finally, it is installed on the rice milling machine through two connecting flanges. When using the rice milling sieve, no sieve holes are blocked, which reduces the probability of rice breakage and improves the quality of rice.

[0004] However, the rice milling screens on the existing rice milling machines are smooth cylindrical in shape, and there is no obstruction structure when milling rice. They rely solely on the friction of the rice grains during rolling, resulting in poor processing efficiency. Utility Model Content

[0005] The purpose of this utility model is to provide a rice milling sieve for a rice milling machine, which aims to solve the problem that the existing rice milling sieves on rice milling machines are smooth cylindrical in shape, without any obstruction structure during rice milling, and rely solely on rolling to make the rice rub for processing, resulting in poor processing efficiency.

[0006] To achieve the above objectives, this utility model provides a rice milling sieve for a rice milling machine, comprising two semi-cylindrical sieve plates, four locking platforms, and an adjustment mechanism. The adjustment mechanism includes two locking frames, two adjustment components, and two connecting components. The four locking platforms are respectively fixedly connected to the connection points of the two semi-cylindrical sieve plates. The two locking frames are slidably connected to the four locking platforms and are respectively located on the upper and lower sides of the two semi-cylindrical sieve plates. The two adjustment components are respectively disposed on the two locking frames. Each adjustment component includes two moving blocks and a transverse bolt. The two moving blocks are fixedly connected to the locking platforms and are slidably connected to both ends of the locking frames. The transverse bolt is threadedly connected to the locking platforms and rotatably connected within the locking frames. The two connecting components are respectively disposed at both ends of the two locking frames.

[0007] The adjustment assembly further includes two adjustment blocks and longitudinal bolts. The two adjustment blocks are slidably connected to the locking frame and are respectively located above the two moving blocks. The two longitudinal bolts are threadedly connected to the two adjustment blocks and are rotatably connected above the two moving blocks.

[0008] The connecting component includes two fixed frames and a mounting ring. The two fixed frames are fixedly connected to the two engaging frames respectively and are located on the same side of the two engaging frames. The mounting ring is fixedly connected between the two fixed frames.

[0009] The connecting assembly further includes multiple reinforcing bolts and multiple reinforcing ribs. The multiple reinforcing bolts are threadedly connected to the two locking frames and pass through the two fixing frames respectively. The multiple reinforcing ribs are fixedly connected between the mounting ring and the two fixing frames respectively.

[0010] The adjustment mechanism further includes two scales and multiple reinforcing ribs. The two scales are fixedly connected to the two locking frames and are located on one side of the two adjustment components. The multiple reinforcing ribs are fixedly connected to the surfaces of the two semi-cylindrical sieve plates.

[0011] This utility model discloses a rice milling sieve for a rice milling machine. When using the sieve, based on the size of the rice grains, two horizontal bolts are tightened. This, in conjunction with four locking platforms and two connecting components, and constrained by four moving blocks, allows two semi-cylindrical sieve plates to slide within two locking frames. This causes the two semi-cylindrical sieve plates to stagger, and the staggering distance is adjusted. After adjustment, the rice milling machine is started, and the sieve rotates. The rice grains entering the sieve are intercepted at the staggered position of the two semi-cylindrical sieve plates as the sieve rolls, increasing the compression between the grains and causing the husks to crack more quickly. Subsequently, with the continuous rolling of the two semi-cylindrical sieve plates, the husks are separated from the rice, and the rice is discharged from the two semi-cylindrical sieve plates. This avoids the problem of existing rice milling machines where the sieve is a smooth cylindrical shape without any obstruction structure, relying solely on rolling to cause friction and resulting in poor processing efficiency. This invention achieves the effect of quickly cracking the husks and improving processing efficiency. Attached Figure Description

The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0019] Please see Figures 1-4 ,in Figure 1 This is a schematic diagram of the overall structure of this utility model; Figure 2 This is a right view between the two adjustment components of this utility model; Figure 3 This is a structural schematic diagram of the movable block of this utility model; Figure 4 This is the utility model Figure 1 A magnified view of a portion of point A in the middle.

[0020] This utility model provides a rice milling sieve for a rice milling machine: it includes two semi-cylindrical sieve plates 1, four locking platforms 2, and an adjustment mechanism. The adjustment mechanism includes two locking frames 3, two adjustment components 4, two connecting components 5, two scales 14, and multiple reinforcing ribs 15. The adjustment components 4 include two moving blocks 6, horizontal bolts 7, two adjusting blocks 8, and vertical bolts 9. The connecting components 5 include two fixing frames 10, mounting rings 11, multiple reinforcing bolts 12, and multiple reinforcing ribs 13. The aforementioned solution solves the problem that the rice milling sieves on existing rice milling machines are entirely smooth cylindrical in shape, without any obstruction structure during rice milling, and rely solely on rolling to cause friction in the rice grains for processing, resulting in poor processing efficiency.

[0021] In this specific embodiment, the four locking platforms 2 are respectively fixedly connected to the connection points of the two semi-cylindrical sieve plates 1. The two locking frames 3 are slidably connected to the four locking platforms 2 and are respectively located on the upper and lower sides of the two semi-cylindrical sieve plates 1. The two adjusting components 4 are respectively disposed on the two locking frames 3. The two moving blocks 6 are fixedly connected to the locking platforms 2 and are respectively slidably connected to both ends of the locking frames 3. The transverse bolts 7 are threadedly connected to the locking platforms 2 and rotatably connected inside the locking frames 3. The two connecting components 5 are respectively disposed at both ends of the two locking frames 3. When using the rice milling sieve, the adjustment is adjusted according to the size of the rice grains. Small, tighten the two horizontal bolts 7, and with the four locking platforms 2 and the two connecting components 5, under the restriction of the four moving blocks 6, the two semi-cylindrical sieve plates 1 slide within the two locking frames 3, thereby making the two semi-cylindrical sieve plates 1 staggered, and adjusting the staggered distance. After the adjustment is completed, start the rice milling machine, and the rice milling sieve will rotate. When the rice entering the rice milling sieve is rolled, it will be intercepted when it passes the staggered position of the two semi-cylindrical sieve plates 1, increasing the compression between the rice grains and making the rice husks crack faster. Then, under the continuous rolling of the two semi-cylindrical sieve plates 1, the rice husks are separated from the rice and discharged from the two semi-cylindrical sieve plates 1.

[0022] Two adjusting blocks 8 are slidably connected to the locking frame 3 and are respectively located above the two moving blocks 6. Two longitudinal bolts 9 are threadedly connected to the two adjusting blocks 8 and are rotatably connected above the two moving blocks 6. When using the adjusting component 4, the two longitudinal bolts 9 are turned so that the two adjusting blocks 8 no longer clamp the locking frame 3. The transverse bolt 7 is rotated. Because it is threadedly connected to the semi-cylindrical screen plate 1, the semi-cylindrical screen plate 1 can slide within the two locking frames 3 by rotation with the cooperation of the two moving blocks 6. With the cooperation of the other adjusting component 4, the degree of overlap of the two semi-cylindrical screen plates 1 can be adjusted. After the adjustment is completed, the two longitudinal bolts 9 are turned so that the two adjusting blocks 8 clamp the locking frame 3 to prevent the semi-cylindrical screen plate from shifting and to ensure the accuracy of the device.

[0023] Secondly, the two fixed frames 10 are respectively fixedly connected to the two locking frames 3 and located on the same side of the two locking frames 3. The mounting ring 11 is fixedly connected between the two fixed frames 10. The two fixed frames 10 can prevent the two semi-cylindrical sieve plates 1 from detaching from one end of the two locking frames 3. The mounting ring 11 is connected to the two locking frames 3 through the two fixed frames 10. With the cooperation of another connecting component 5, the two locking frames 3 are fixed by the two fixed frames 10. When using a rice milling sieve, it is also connected and installed through the mounting ring 11 in the two connecting components 5.

[0024] Meanwhile, multiple reinforcing bolts 12 are threadedly connected to the two locking frames 3 respectively and pass through the two fixing frames 10 respectively. Multiple reinforcing ribs 13 are fixedly connected between the mounting ring 11 and the two fixing frames 10 respectively. Multiple reinforcing bolts 12 can make the connection between the two fixing frames 10 and the two locking frames 3 more secure. Multiple reinforcing ribs 13 can make the connection between the screw fixing frame 10 and the mounting ring 11 more secure, thereby increasing the robustness of the device. When the two locking frames 3 or the two fixing frames 10 need to be cleaned or repaired, multiple reinforcing bolts 12 can be unscrewed to separate the two locking frames 3 from the two fixing frames 10, which is convenient for cleaning and maintenance.

[0025] Finally, the two scales 14 are fixedly connected to the two locking frames 3 respectively, and are located on one side of the two adjusting components 4 respectively. The multiple reinforcing ribs 15 are fixedly connected to the surfaces of the two semi-cylindrical screen plates 1 respectively. When using the adjusting components 4, the two moving blocks 6 will move with the two moving blocks 6 under the action of the two longitudinal bolts 9. At this time, the moving distance of the semi-cylindrical screen plates 1 can be observed through the scales 14, thereby accurately controlling the degree of overlap of the two semi-cylindrical screen plates 1 and improving the accuracy of the device. The multiple reinforcing ribs 15 can effectively prevent the two semi-cylindrical screen plates 1 from deforming and extend the service life of the device.

[0026] When using the rice milling sieve, depending on the size of the rice grains, the two adjusting components 4, in conjunction with the four locking platforms 2 and the two connecting components 5, and under the constraint of the four moving blocks 6, allow the two semi-cylindrical sieve plates 1 to slide within the two locking frames 3, thereby causing the two semi-cylindrical sieve plates 1 to stagger. The staggering distance is adjusted, and after adjustment, the rice milling machine is started, and the rice milling sieve rotates. The rice grains entering the sieve are intercepted when passing the staggered position of the two semi-cylindrical sieve plates 1, increasing the compression between the grains and causing the husks to crack more quickly. Subsequently, with the continuous rolling of the two semi-cylindrical sieve plates 1, the husks are separated from the rice, and the grains are arranged side by side. Two semi-cylindrical sieve plates 1 are provided. When using the adjusting component 4, the two longitudinal bolts 9 are turned so that the two adjusting blocks 8 no longer clamp the locking frame 3. The transverse bolt 7 is rotated, and because it is threadedly connected to the semi-cylindrical sieve plate 1, the semi-cylindrical sieve plate 1 can slide within the two locking frames 3 by rotation with the cooperation of the two moving blocks 6. With the cooperation of the other adjusting component 4, the degree of overlap of the two semi-cylindrical sieve plates 1 can be adjusted. After adjustment, the two longitudinal bolts 9 are turned so that the two adjusting blocks 8 clamp the locking frame 3 to prevent the semi-cylindrical sieve plates from shifting, ensuring the accuracy of the device, and making it suitable for rice of different sizes, improving efficiency. The device's applicability is enhanced; the mounting ring 11 is connected to the two locking frames 3 via the two fixing frames 10, and with the cooperation of another connecting component 5, the two locking frames 3 are fixed by the two fixing frames 10; when using a rice milling sieve, it is also connected and installed via the mounting ring 11 within the two connecting components 5; multiple reinforcing bolts 12 make the connection between the two fixing frames 10 and the two locking frames 3 more secure, and multiple reinforcing ribs 13 make the connection between the screw fixing frame 10 and the mounting ring 11 more secure, thereby increasing the device's robustness, and when the two locking frames 3 or the two fixing frames 10 need cleaning or maintenance, they can be unscrewed. Multiple reinforcing bolts 12 separate the two locking frames 3 from the two fixed frames 10, facilitating cleaning and maintenance. When using the adjusting component 4, the two moving blocks 6 move along with the two longitudinal bolts 9. At this time, the movement distance of the semi-cylindrical sieve plate 1 can be observed through the scale 14, thereby accurately controlling the degree of overlap of the two semi-cylindrical sieve plates 1, improving the accuracy of the device, and avoiding the problem that the rice milling sieve on existing rice milling machines is a smooth cylindrical shape, without any obstruction structure during rice milling, and relies solely on rolling to make the rice husks rub against each other, resulting in poor processing efficiency. This achieves the effect of quickly cracking the rice husks and improving processing efficiency.

Those skilled in the art can understand that all or part of the processes for implementing the above embodiments and equivalent changes made in accordance with the claims of this application still fall within the scope of this application.
