[0002] A rice milling device is a mechanical device used to remove the husk and whiten brown rice. The working principle of the rice milling device is mainly based on the mechanical grinding and friction of brown rice in the whitening chamber. When the brown rice enters the whitening chamber from the feed hopper, it is subjected to the high-speed rotation of the milling rollers and the friction of the rice sieve. The husk of the brown rice gradually falls off, and the rice bran is discharged through the sieve holes. The whitening gap between the milling rollers and the rice sieve can be adjusted as needed to control the degree of rice milling and the quality of the rice.

[0003] In existing technologies, during the feeding of brown rice by workers in existing rice milling devices, the brown rice may cause blockage at the feed inlet due to its own characteristics. Once blockage occurs, it will not only affect production efficiency, but may also damage the equipment and increase operating costs.

[0004] Therefore, this utility model provides a closed-type rice milling anti-clogging device. Utility Model Content

[0022] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0023] like Figures 1 to 5 As shown in the embodiment of this utility model, a closed rice milling anti-clogging device includes a first housing 1; a milling chamber 3 is provided inside the first housing 1; support legs 4 are fixedly connected to both sides of the first housing 1; a second housing 5 is fixedly connected to the top of the first housing 1; a feeding chamber 6 is fixedly connected to the top of the second housing 5; a folding plate 7 is slidably connected inside the feeding chamber 6; a feeding port 8 is opened at the top of the second housing 5, and the feeding port 8 extends into the interior of the milling chamber 3; a power component is provided on one side of the second housing 5; the power component is used to drive the movement of the folding plate 7. During operation, by setting the first housing 1, the first housing 1 is... The milling chamber 3 is installed inside to mill brown rice. The staff can place the material on the folding plate 7 in the feed hopper 6. Because the folding plate 7 is inclined, the material will slide downwards. The power component can drive the folding plate 7 when the staff pours the rice, so that the folding plate 7 forms a slight up and down vibration in the feed hopper 6, which can make the rice grains flow smoothly and reduce blockage. The rice grains on the folding plate 7 can smoothly pass through the feed hopper 6 and enter the milling chamber 3. One side of the folding plate 7 extends into the second box 5, so that the material will not fall at the interface between the folding plate 7 and the second box 5, causing material waste.

[0024] The power component includes a first motor 9; the first motor 9 is fixedly connected to one side of the second housing 5; the output end of the first motor 9 is provided with a first rotating rod 10; one end of the first rotating rod 10 passes through the second housing 5 and is fixedly connected to a turntable 11; a set of protrusions 12 are fixedly connected to the turntable 11; the set of protrusions 12 are respectively rotatably connected to the bottom end of the folding plate 7. During operation, by fixing the first motor 9 to one side of the second housing 5 and setting the first rotating rod 10 at the output end of the first motor 9, the operator can turn on the first motor 9 before pouring rice grains into the feeding hopper 6, so that the first rotating rod 10 drives the turntable 11 and the protrusions 12 on the turntable 11 to rotate, so that the protrusions 12 contact the folding plate 7 in sequence. The folding plate 7 will produce a slight shaking effect in the sequential contact and non-contact of the set of protrusions 12, so that the rice grains on the folding plate 7 can smoothly pass through the feeding hopper 6 and enter the interior of the second housing 5.

[0025] The second housing 5 has a first support column 13 fixedly connected inside; the top of the first support column 13 has an arc-shaped groove 14; an auger 15 is rotatably connected inside the arc-shaped groove 14; the auger 15 is fixedly connected to the first rotating rod 10. During operation, by fixing the first support column 13 inside the second housing 5 and opening the arc-shaped groove 14 at the top of the first support column 13, and setting the auger 15 inside, when rice grains enter the second housing 5 through the feed bin 6, the auger 15 can convey the rice grains. During the conveying process of the auger 15 conveyor, the rice grains can be evenly distributed on the spiral blades, avoiding stratification, separation and other phenomena. This helps to ensure the uniformity and quality stability of the rice grains, and can obtain a more consistent rice milling effect after entering the milling bin 3.

[0026] The milling chamber 3 is fixed inside the first housing 1; a rice sieve 16 is fixed inside the milling chamber 3; a second motor 17 is fixed to one side of the milling chamber 3; a second rotating rod 18 is provided at the output end of the second motor 17; one end of the second rotating rod 18 passes through the inside of the milling chamber 3 and is rotatably connected to one side inside the milling chamber 3; a milling roller 19 is fixed to the second rotating rod 18; the milling roller 19 is rotatably connected to the inside of the rice sieve 16; a first discharge port 22 is opened on one side of the milling chamber 3. During operation, by fixing the milling chamber 3 inside the first housing 1, the rice sieve 16 and milling roller 19 provided inside the milling chamber 3 are existing technologies used to crush rice bran and cooperate to perform rice milling work, crushing the rice bran off the rice grains.

[0027] Both sides of the first box 1 are fixed with a rice bran suction fan 20. During operation, the rice bran can be absorbed from the milling bin 3 by installing the rice bran suction fan 20 on both sides of the first box 1.

[0028] A second discharge port 23 is provided on one side of the first box 1. During operation, the rice bran that cannot be adsorbed by the bran suction fan 20 can be discharged from the second discharge port 23 because the second discharge port 23 is inclined.

[0029] Working principle: By setting up a first chamber 1, and installing a milling bin 3 inside the first chamber 1, brown rice can be milled. The worker can place the material on the folding plate 7 inside the feed hopper 6. Because the folding plate 7 is inclined, the material will slide downwards. The power component can drive the folding plate 7 when the worker pours the rice, causing the folding plate 7 to vibrate slightly up and down inside the feed hopper 6. This allows the rice grains to flow smoothly and reduces blockages, enabling the rice grains on the folding plate 7 to smoothly pass through the feed hopper 6 and enter the milling bin 3. One side extends into the second housing 5, preventing materials from falling at the interface between the folding plate 7 and the second housing 5, thus avoiding material waste. A first motor 9 is fixed to one side of the second housing 5, and a first rotating rod 10 is installed at the output end of the first motor 9. Before pouring rice grains into the feed hopper 6, the operator can turn on the first motor 9, causing the first rotating rod 10 to drive the turntable 11 and the protrusions 12 on the turntable 11 to rotate. This causes the protrusions 12 to sequentially contact the folding plate 7. The folding plate 7 will then experience slight vibrations as a set of protrusions 12 sequentially contact and do not contact each other. The dynamic effect allows the rice grains on the folded plate 7 to smoothly pass through the feed hopper 6 and enter the second housing 5. A first support column 13 is fixed inside the second housing 5, and an arc-shaped groove 14 is opened at the top of the first support column 13, with an auger 15 installed inside. After the rice grains pass through the feed hopper 6 and enter the second housing 5, the auger 15 can convey the rice grains. During the conveying process of the auger 15 conveyor, the rice grains can be evenly distributed on the spiral blades, avoiding stratification and separation. This helps to ensure the uniformity and quality stability of the rice grains. A more consistent rice milling effect can be obtained after milling bin 3. Milling bin 3 is fixed in the first box 1. The rice sieve 16 and milling roller 19 set in milling bin 3 are existing technologies used to crush rice bran and work together to mill rice, crushing the rice bran off the rice grains. Rice bran can be absorbed from milling bin 3 by installing bran suction fans 20 on both sides of the first box 1. A second discharge port 23 is opened on one side of the first box 1. Because the second discharge port 23 is inclined, rice bran that cannot be absorbed by the bran suction fans 20 can be discharged from the second discharge port 23.
