[0021] like Figure 1-4 As shown, the present invention proposes a rice hulling device, comprising a chassis 1, a feed box 2, a crushing assembly 5, a speed reducer 6, and a dust removal component 7. A feed inlet 3 is provided at the upper end of the chassis 1. The feed box 2 is disposed at the lower end of the chassis 1; a discharge port 4 is provided on one side of the feed box 2. The crushing assembly 5 is disposed within the chassis 1, and the rice grains are crushed against the inner wall of the inner cavity 51 by the rotation of the crushing roller 55, thereby hulling the rice grains. The speed reducer 6 is disposed within the feed inlet 3 to reduce the feeding speed of the rice grains. The dust removal component 7 is disposed within the feed box 2 to remove the removed hulls and dust.

[0022] Further description, there are two groups of crushing components 5 vertically arranged in the chassis 1. The rice grains can be crushed twice to avoid that some rice grains are not crushed and not shelled.

[0023] To further illustrate, the housing 1 has two horizontally symmetrical inner chambers 51. These two inner chambers 51 are interconnected; the upper inner chamber 51 communicates with the feed inlet 3, while the lower inner chamber 51 communicates with the discharge box 2. The rolling assembly 5 includes a rotating shaft 53 rotatably mounted on the inner walls of each of the two inner chambers 51. One end of the rotating shaft 53 is connected to the drive end of a drive mechanism 54 mounted on the housing 1, on which a rolling roller 55 is eccentrically mounted. The drive mechanism 54 is a motor. The inner chamber 51 is cylindrical, with an inner diameter slightly larger than that of the rolling roller 55. The rotation of the rolling roller 55 presses the rice grains against the inner wall of the inner chamber 51, thereby removing the rice shells.

[0024] Further, the sidewalls of the rolling roller 55 are uniformly provided with multiple raised ridges 56. The inner wall of the inner cavity 51 is uniformly provided with multiple raised ridges 52 that engage with the raised ridges 56. Both sides of the raised ridges 52 are provided with adjustable bevels. The engagement of the raised ridges 52 with the raised ridges 56 allows for more precise rolling of the rice grains, ensuring they are fully hulled and improving the hulling rate. When the raised ridges 56 are inserted into the gaps between the raised ridges 52, a certain gap remains between them and the inner cavity 51, allowing them to rub the rice grains, hulling them without crushing them, thus preserving their integrity. The arrangement of the raised ridges 52 and 56 also hinders the descent of the rice grains, slowing their rate of descent and ensuring they are fully crushed. The adjustable bevels ensure that the rice grains fall freely without accumulating.

[0025] To further illustrate, the speed reducer 6 includes a second rotating shaft 61 rotatably mounted on the side wall of the feed port 3. One end of the second rotating shaft 61 is connected to the driving end of a second driving mechanism 62 mounted on the feed port 3, on which a plurality of baffles 63 are evenly distributed. The second driving mechanism 62 is a motor. This allows the rice grains to enter the chassis 1 intermittently in batches, reducing the feeding speed and preventing a large amount of rice from being dumped into the chassis 1 and accumulating, resulting in insufficient crushing.

[0026] To further explain, the impurity removal component 7 includes a filter plate 71 arranged in the discharge box 2; the filter plate 71 is arranged below the inner cavity 51, one end of which is connected to the upper end of the fixed plate 72 arranged in the discharge box 2, and the other end extends to the discharge port 4; the filter plate 71 is arranged at an angle, which can filter the crushed rice residue, thereby ensuring that the rice grains flowing out of the discharge port 4 are complete and full; the fixed plate 72 separates the discharge box 2 into a collection chamber; a blower 73 is also provided on the discharge box 2; the air outlet of the blower 73 is opposite to the collection chamber; the blower 73 can blow the crushed rice husks into the collection chamber to collect the rice husks.

[0027] The working principle of the present invention is as follows: During operation, rice grains are first poured into the chassis 1 from the feed port 3. Simultaneously, the second drive mechanism 62 is activated to rotate the second shaft 61 and the plurality of baffles 63, causing the rice grains to fall between two adjacent baffles 63 and then enter the inner cavity 51 in batches following the rotation of the second shaft 61. Next, the first drive mechanism 54 is activated to rotate the first shaft 53 and the rolling roller 55, causing the rolling roller 55 to roll along the inner wall of the inner cavity 51, thereby engaging the second rib 56 and the first rib 52 to roll the rice grains and help hull the rice grains. Finally, the blower 73 is activated, and the hulled rice grains flow out of the discharge port 4 along the filter plate 71, while the removed hulls fall into the collection chamber along with the air blown by the blower 73.

[0028] The embodiments of the present invention are described in detail above with reference to the accompanying drawings, but the present invention is not limited thereto. Various changes can be made within the knowledge scope of those skilled in the art without departing from the purpose of the present invention.
