Description

Technical Field

[0001] This utility model relates to the field of rice screening technology, and in particular to a layered rotary rice destone removal device. Background Technology

[0002] Rice is a finished product made from paddy through cleaning, hulling, milling, and finishing processes. It is also called paddy rice. Rice is a staple food for most people in my country. A unique component of rice, oryzanol, is known as a "beauty element" as it is a plant-based melanin inhibitor. It is mild, has no side effects, and can reduce capillary fragility and improve peripheral blood circulation, thus preventing chapped skin and improving skin tone. The biological value of rice protein is comparable to that of soybeans, and its amino acid composition is well-balanced, closely resembling the optimal amino acid ratio for protein as recognized by the World Health Organization. Rice protein has a digestibility rate exceeding 90%, making it highly nutritious.

[0003] Patent document CN107159571A discloses a layered rotary rice destone removal device, including a cylinder, a discharge plate connected to the lower outer end of the discharge port, and a scraper located on the upper end of the fine sieve plate near the inner wall of the cylinder. In this invention, rice enters from the feed hopper, and a motor drives the coarse and fine sieve plates to rotate. The rice first falls onto the coarse sieve plate, and the rotating plates prevent clogging, improving screening efficiency. Furthermore, the conical shape of the coarse and fine sieve plates increases the flowability of the rice, facilitating screening. Large stones are screened out by the coarse sieve plate and thrown onto the support plate, while small stones fall through the fine sieve plate. The rice flows directly out from the discharge port, and a blower at the bottom blows air upwards, along the sieve holes on the coarse sieve plate, thus blowing out bran and debris. The large area of ​​the coarse sieve plate disperses the rice more evenly, making it easier to remove bran and debris, resulting in a cleaner and more effective cleaning process.

[0004] While the above application makes it easier to blow out the rice bran and residue, resulting in a cleaner product and improved cleaning effect, it cannot remove and separate stones of different sizes from the rice during actual use. This increases the risk of consuming the rice during cooking and may also damage teeth. Utility Model Content

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A layered rotary rice destone removal device includes a base, with vibrators fixedly installed at the four corners of the upper surface of the base, a horizontal plate fixedly installed on the top of the vibrators, and a filter assembly fixedly installed on the top of the horizontal plate.

[0008] The filter assembly includes a cylinder fixedly mounted on a horizontal plate, a conical tube connected to the bottom of the cylinder, a discharge pipe connected to the bottom of the conical tube, a hydraulic rod fixedly mounted on the top of the cylinder, a cover fixedly mounted on the top of the hydraulic rod, a motor fixedly mounted on the bottom of the cover, a rotating rod fixedly mounted on the output shaft of the motor, a first stirring blade and a second stirring blade fixedly mounted on the surface of the rotating rod, a receiving ring fixedly mounted inside the cylinder, a groove formed on the upper surface of the receiving ring, and a conical mesh fixedly mounted on the top of the receiving ring.

[0009] The filter components are designed to separate pebbles from rice grains, first removing larger pebbles and then further filtering out smaller sand and gravel to ensure the cleanliness of the rice and reduce the risk of consuming it during cooking, while also preventing damage to teeth.

[0010] In a preferred embodiment, support tubes are fixedly installed at the four corners of the bottom of the base, telescopic rods are fixedly installed on the inner top wall of the support tubes, brackets are fixedly installed on the top of the telescopic rods, and rollers are rotatably connected inside the brackets via a rotating shaft.

[0025] As can be seen from the above, the layered rotary rice destone removal device provided by this utility model has the following technical effects.

[0026] Firstly, the filter components allow for layered screening of pebbles in the rice. Pebbles larger than rice grains are first removed, followed by further sedimentation to remove finer sand and gravel, ensuring the cleanliness of the rice and reducing the risk of consuming it during cooking. This also prevents damage to teeth.

[0027] Secondly, the dust extraction pipe can collect dust from the rice during screening, thus avoiding pollution of the surrounding environment. At the same time, the support pipe and telescopic rod can adjust the position of the rollers during use. When the rollers are outside the support pipe, they can support the movement of the device. When the rollers are inside the support pipe, the support pipe supports the device and maintains the stability of the device. Attached Figure Description

[0037] The filter assembly 4 includes a cylinder 400 fixedly mounted on a horizontal plate 3. A conical tube 401 is connected to the bottom of the cylinder 400, and a discharge pipe 402 is connected to the bottom of the conical tube 401. A hydraulic rod 403 is fixedly mounted on the top of the cylinder 400, and a cover 404 is fixedly mounted on the top of the hydraulic rod 403. A motor 405 is fixedly mounted on the bottom of the cover 404. A rotating rod 406 is fixedly mounted on the output shaft of the motor 405.

Both the first stirring blade 407 and the second stirring blade 408 are conical with their tips pointing upwards. A rubber rubber mat is fixedly mounted on the inner side of the first stirring blade 407. The first stirring blade 407 is adapted to the conical mesh 410. The surface of the rubber strip 416 is in contact with the surface of the conical mesh 410. The rubber strip 416 can be used to move the rice grains on the conical mesh 410 during use, thus accelerating the screening of rice grains. The conical tip of the second stirring blade 408 points downward, and the taper of the second stirring blade 408 is adapted to the taper of the conical tube 401. When the hydraulic rod 403 is retracted to its shortest length, the bottom of the cover 404 contacts the top of the cylinder 400. The inner side of the first stirring blade 407 contacts the surface of the conical mesh 410, and a gap is left between the outer side of the second stirring blade 408 and the conical tube 401.

[0038] A receiving ring 409 is fixedly installed inside the cylinder 400. A groove is formed on the upper surface of the receiving ring 409, and a conical mesh 410 is fixedly installed on the top of the receiving ring 409. The filter assembly 4 achieves a layered screening effect for stones in the rice. It first filters out stones larger than rice grains, and then further filters out finer sand and gravel through sedimentation, ensuring the cleanliness of the rice and reducing the risk of consuming the rice during cooking. It also prevents damage to teeth. The bottom of the discharge pipe 402 penetrates the base 1 and extends to the outside of the base 1. A sliding hole is formed on the base 1 for the discharge pipe 402 to slide. A valve 411 is connected to the surface of the discharge pipe 402. The sliding hole ensures that the discharge pipe 402 does not interfere with the vibration of the components when the vibrator 2 is working. The cover 404 has a protective sleeve 412 fixedly installed at the bottom. The surface of the protective sleeve 412 is slidably connected to the inner wall of the cylinder 400. The protective sleeve 412 can cover the top of the cylinder 400 during use, thereby maintaining the airtightness of the device. The upper surface of the cover 404 is connected to the feed pipe 413 and the dust extraction pipe 414 on both sides respectively. One end of the dust extraction pipe 414 is connected to the air inlet of the external exhaust fan, and one end of the feed pipe 413 is connected to the discharge port of the external conveyor. The dust extraction pipe 414 can collect dust in the rice during rice screening, thereby avoiding pollution of the surrounding environment. A stone discharge pipe 415 is inserted into one side of the cylinder 400. One end of the stone discharge pipe 415 is connected to one side of the receiving ring 409.

[0039] Reference Figure 1 and Figure 4 In a preferred embodiment, support tubes 5 are fixedly installed at the four corners of the bottom of the base 1. Telescopic rods 6 are fixedly installed on the inner top wall of the support tubes 5. A bracket 7 is fixedly installed on the top of the telescopic rods 6. Rollers 8 are rotatably connected inside the bracket 7 via a rotating shaft. The position of the rollers 8 can be adjusted during use of the support tubes 5 and the telescopic rods 6. When the rollers 8 are outside the support tubes 5, they can support the movement of the device. When the rollers 8 are inside the support tubes 5, the support tubes 5 support the device and maintain the stability of the device. The two sides of the bracket 7 are slidably connected to the two sides of the inner wall of the support tubes 5, and the bracket 7 is adapted to the support tubes 5.

[0040] Working principle: During use, rice is added into the cylinder 400 through the feed pipe 413. Then, the motor 405 is controlled to work, and the motor 405 drives the first stirring blade 407 and the second stirring blade 408 on the rotating rod 406 to rotate. The rice is screened by the conical mesh 410, so that the rice falls into the conical tube 401 through the mesh of the conical mesh 410. Larger stones in the rice remain on the conical mesh 410 and fall into the receiving ring 409, which can be discharged through the stone discharge pipe 415. At the same time, the vibrator 2 is controlled to work, and fine sand and gravel fall into the conical tube 401 along with the rice. During the vibration process, the second stirring blade 408 stirs the rice in the upper layer. Since the specific gravity of rice is less than that of sand and gravel, after the vibration and stirring process, the sand and gravel will fall to the bottom of the conical tube 401. Then, the valve 411 is opened to release a portion of the rice, and the remaining rice is clean rice without sand and gravel.

[0041] The above description is merely a preferred embodiment of this utility model, but the protection scope of this utility model is not limited thereto. The substitutions may be replacements of some structures, devices, or method steps, or they may be complete technical solutions. Equivalent substitutions or modifications made based on the technical solution and inventive concept of this utility model should all be covered within the protection scope of this utility model.
