Description

Technical Field

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

[0002] Rice polishing machines are mainly used to polish rice after milling. By removing bran and minor imperfections from the surface of the rice, the rice grains have a smooth appearance, which improves the commercial value and taste of the rice.

[0003] The rice polishing machine disclosed in CN219722965U, which can remove broken rice, has a removal component that can separate damaged rice from whole rice after polishing, avoiding the need for secondary screening when damaged rice is mixed with whole rice. However, the above device still has the following drawbacks: Although the above-mentioned device achieves the separation of broken rice from whole rice, its simple single-layer screen can only perform coarse filtration of rice. Either the screen holes are too large, causing large broken rice grains (more than 2 / 3 the length of a whole rice grain) that can be sold as good products to be mixed with small broken rice grains that cannot be sold as waste, resulting in product waste; or the screen holes are too small, causing large broken rice grains to be mixed with whole rice grains. This means that if manufacturers want to produce high-quality rice that consists entirely of whole rice grains, they need to perform a subsequent sieving operation, which reduces efficiency and increases costs. Utility Model Content

[0004] This utility model aims to at least partially solve one of the technical problems in the above-mentioned technologies.

[0005] Therefore, one objective of this utility model is to propose a rice polishing machine that, through a screening mechanism combined with a feeding mechanism and a vibration mechanism, can quickly perform multi-stage screening of polished rice, accurately separating whole grains of rice, large-grained broken rice that can be sold, and small-grained broken rice that cannot be sold, thereby improving the efficiency and effectiveness of screening and greatly facilitating manufacturers to produce rice of different qualities.

[0006] To achieve the above objectives, the first aspect of this utility model provides a rice polishing machine, comprising: a polishing machine body, a base plate, a sieving barrel, a screening mechanism, a material spreading mechanism, and a vibration mechanism, wherein the polishing machine body is used for polishing rice; the sieving barrel is disposed on the upper part of the base plate; the screening mechanism includes multi-stage screens and multiple collection boxes, wherein the multi-stage screens are arranged in a conical shape and disposed inside the sieving barrel; the multiple collection boxes are respectively disposed inside the sieving barrel and located below the multi-stage screens; the material spreading mechanism is disposed on the sieving barrel; and the vibration mechanism is disposed between the sieving barrel and the base plate.

[0016] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0017] The following describes an embodiment of the rice polishing machine of this utility model with reference to the accompanying drawings.

[0018] like Figures 1-6 As shown, the rice polishing machine of this utility model embodiment may include: polishing machine body 1, base plate 2, screening barrel 3, screening mechanism 4, material spreading mechanism 5, and vibration mechanism 6.

[0019] The polishing machine body 1 is used to polish rice.

[0020] Understandably, the lower part of the polishing machine body 1 is equipped with self-locking casters, which can move freely or stop.

[0021] The screening bucket 3 is located on the upper part of the base plate 2.

[0022] It should be noted that the base plate 2 is placed on the ground and close to the polishing machine body 1, and the discharge port of the polishing machine body 1 is aligned with the inside of the screening barrel 3, so that the polished rice can be discharged into the screening barrel 3.

[0023] The screening mechanism 4 includes a multi-stage screen 401 and multiple collection boxes 402.

[0024] The multi-stage screen 401 is arranged in a cone shape and is located inside the screening barrel 3, while multiple collection boxes 402 are respectively located inside the screening barrel 3 and below the multi-stage screen 401.

[0025] It should be noted that the multi-stage screen 401 described in this embodiment consists of three arc-shaped circular hole screens. The part corresponding to the discharge port of the polishing machine body 1 is a small-diameter circular hole screen (1mm in diameter, which can filter out small broken rice particles). Taking the top view as a reference, in a counterclockwise direction, there are medium-diameter circular hole screens (1.5mm in diameter, which can filter out large broken rice particles) and large-diameter circular hole screens (2mm or more in diameter, which can filter out whole rice particles).

[0026] In addition, it should be noted that the collection boxes 402 are designed in a fan shape and arranged in a circular array to be compatible with the screening barrel 3 and the multi-stage screen 401. Each collection box 402 corresponds to a different screen hole on the multi-stage screen 401. The collection boxes 402 are equipped with handles for easy picking and putting.

[0027] The material spreading mechanism 5 is installed on the screening barrel 3.

[0028] Understandably, the spreading mechanism 5 is used to evenly spread the rice that is fed into the screening barrel 3 in a counterclockwise direction, so that the rice passes through the small-diameter sieve, medium-diameter sieve and large-diameter sieve in sequence, thereby realizing the grading and screening of the rice.

[0029] The vibration mechanism 6 is installed between the screening barrel 3 and the bottom plate 2.

[0030] Understandably, the vibration mechanism 6 is used to drive the screening bucket 3 to vibrate, so that the rice grains can be evenly dispersed and fall quickly through the multi-stage screen 401, avoiding clogging of the screen holes.

[0031] Specifically, during the rice processing, after the rice milling machine completes the rice milling and chaff removal process, relevant personnel feed the rice into the feed inlet of the polishing machine body 1 and start the polishing machine body 1 to polish the rice.

[0032] After polishing, the rice is discharged from the outlet of the polishing machine body 1 and falls into the screening barrel 3. At this time, the staff simultaneously starts the spreading mechanism 5 and the vibration mechanism 6. While the vibration mechanism 6 drives the screening barrel 3 to vibrate, the spreading mechanism 5 pushes the rice to be evenly spread counterclockwise along the surface of the multi-stage screen 401. During this period, small broken rice particles, large broken rice particles and whole rice grains fall into the corresponding collection boxes 402 through the small-diameter screen, medium-diameter screen and large-diameter screen on the multi-stage screen 401, respectively. After all the rice has been polished and screened, the polishing machine body 1 is moved aside, and the collection boxes 402 are taken out from the screening barrel 3 by the handle, so that the rice can be processed in subsequent operations.

[0033] In one embodiment of this utility model, such as Figure 5 As shown, the screening barrel 3 includes a base 301, a support frame 302, and a retaining ring 303.

[0034] The base 301 is located on the upper part of the base plate 2, the support frame 302 is located on the upper part of the base 301, the support frame 302 is composed of multiple partitions, each collection box 402 is located between two adjacent partitions, the multi-stage screen 401 is connected to the upper part of the support frame 302, and the retaining ring 303 is located on the upper part of the support frame 302.

[0035] It should be noted that, in this embodiment, the base 301 is welded and fixed to the lower end of the support frame 302, the retaining ring 303 is welded and fixed to the upper end of the support frame 302, and the upper part of the partition is set as an inclined side with the same slope as the conical surface of the multi-stage screen 4, so that the support frame 302 can be snapped and fixed to the multi-stage screen 4, and play a supporting role for the multi-stage screen 4.

[0036] In one embodiment of this utility model, such as Figure 2 and Figure 3 As shown, the material spreading mechanism 5 includes a mounting frame 501, a rotating block 502, two scrapers 503, two brushes 504, and a motor 505.

[0037] The mounting frame 501 is located on the upper part of the retaining ring 303. The rotating block 502 is rotatably connected to the upper end of the multi-stage screen 401. Two scrapers 503 are respectively connected to the rotating block 502 and are in contact with the surface of the multi-stage screen 401. Two brushes 504 are respectively connected to the scrapers 503 and are in contact with the surface of the multi-stage screen 401. The motor 505 is mounted on the mounting frame 501, and its output end passes through the mounting frame 501 and is connected to the rotating block 502.

[0038] It should be noted that, in this embodiment, the mounting bracket 501 and the retaining ring 303 are connected by bolts, a bearing is provided between the rotating block 502 and the multi-stage screen 401, the brush 504 is connected to the scraper 503 by bolts, and the two brushes 504 are respectively fixed on the opposite side of the two scrapers 503.

[0039] Specifically, after the rice is polished, it is discharged into the screening barrel 3 through the discharge port of the polishing machine body 1. The rice first falls into the small-diameter screen hole part of the multi-stage screen 401. With the vibration of the vibration mechanism 6, the small broken rice particles will fall directly from this part into one of the collection boxes 402. The remaining large broken rice particles and whole rice grains remain on the upper part of the multi-stage screen 401.

[0040] By starting the motor 505 and cooperating with the rotating block 502 to drive the scraper 503 to rotate counterclockwise, the scraper 503 will push the remaining rice along the surface of the multi-stage screen 401. When it moves to the medium-diameter screen, large broken rice particles will fall from this part into one of the collection boxes 402, while the remaining whole rice grains will remain on the upper part of the multi-stage screen 401. The scraper 503 continues to push the remaining rice along the surface of the multi-stage screen 401. When it moves to the large-diameter screen, all the whole rice grains will fall from this part into one of the collection boxes 402. By keeping the scraper 503 rotating continuously in this process, the rice can be graded and screened.

[0041] Understandably, the bristles of the brush 504 can extend into the sieve holes of the multi-stage sieve 401 to sweep away the rice grains clogging the sieve holes. With the continuous rotation of the scraper 503, the multi-stage sieve 401 is thoroughly and effectively cleaned, ensuring the efficiency and effectiveness of rice sieving.

[0042] In one embodiment of this utility model, such as Figure 6 As shown, the vibration mechanism 6 includes multiple telescopic rods 601, multiple springs 602, and a vibration motor 603.

[0043] Multiple telescopic rods 601 are connected between the base 301 and the base plate 2, multiple springs 602 are respectively sleeved on the outside of the telescopic rods 601, and the vibration motor 603 is installed at the bottom of the base 301.

[0044] It should be noted that the number of telescopic rods 601 and springs 602 described in this embodiment is at least four. The springs 602 are high-strength compression springs, which, together with the telescopic rods 601, can effectively support the screening barrel 3. The telescopic rods 601 are connected to the base 301 and the base plate 2 by bolts or by welding.

[0045] Specifically, when the rice falls onto the upper part of the multi-stage screen 401, the vibration motor 603 is started, and together with the telescopic rod 601 and the spring 602, the screening barrel 3 is driven to vibrate, so that the rice is evenly dispersed and the screening efficiency is improved.

[0046] In summary, this rice polishing machine, through a screening mechanism combined with a feeding mechanism and a vibration mechanism, can quickly perform multi-stage screening of polished rice. This allows rice grains of different sizes to fall into corresponding collection boxes through different sieve holes on the multi-stage screen, thereby accurately separating whole rice grains, large breakable rice grains that can be sold, and small breakable rice grains that cannot be sold. This improves the efficiency and effectiveness of screening and greatly facilitates manufacturers in producing rice of different qualities.
