[0035] Embodiment:

[0036] A germinated rice bran removal device includes an upper frame body 10 and a lower frame body 20 that are connected to each other up and down. The top of the upper frame body 10 is provided with a feed inlet. A milling component 50 is further arranged inside the upper frame body 10. One end of the milling component 50 is rotationally connected to a driving component 40 arranged inside the lower frame body 20;

[0037] One end of the upper frame body 10 away from the driving component 40 is provided with a first discharge port and a blanking port. A first discharge hopper 80 is connected to the outside of the first discharge port. A diversion pipe 60 is communicated with the outside of the blanking port. A separation component 70 is connected to the top of the diversion pipe 60. The discharge end of the separation component 70 is communicated with a second discharge hopper 90;

[0038] The second discharge hopper 90 includes a first discharge cover 910 and a second discharge cover 920. The first discharge cover 910 and the second discharge cover 920 are vertically arranged. A second mesh sheet 930 is further arranged in the vertical cavity of the first discharge cover 910 and the second discharge cover 920.

[0039] It should be noted that the milling component 50 can perform preliminary milling on the shelled rice to remove the bran. The white rice containing bran after preliminary screening flows into the separation component 70 through the diversion pipe 60. The strong air flow of the separation component 70 effectively separates the bran from the white rice, and the bran separated by colliding with the second mesh sheet 930 is discharged through the first discharge cover 910, while the white rice is discharged through the second discharge cover 920, thus ensuring the efficient removal of impurities.

[0040] Specifically, the operator can control the power of the milling component 50 by adjusting the rotation speed of the driving component 40 according to actual needs, so as to achieve precise control of the milling intensity. The separation component 70 adopts air separation technology, and the light rice bran can be separated from the heavy white rice through the air flow. The discharge end of the separation component 70 is connected with a second discharge hopper 90. The structural design of the second discharge hopper 90 can prevent the mixing of rice bran and white rice and ensure the separation effect. The two discharge hood ports in the second discharge hopper 90 can be respectively connected with their own collection bags, and the collection bags are used to collect the separated rice bran and white rice. The material of the collection bag should have good air permeability and wear resistance to ensure that it will not be damaged during long-term use and is convenient for cleaning and replacement.

[0041] With reference to the accompanying drawings of the specification Figures 1-9 As shown, the upper frame body 10 includes a first outer shell 110, a first cover 120 and a second cover 130. The first cover 120 and the second cover 130 are respectively installed at both ends of the first outer shell 110. The first discharge port is opened at the bottom of the first cover 120. The first discharge hopper 80 is communicated with the first cover 120 through the first discharge port. Both ends of the milling component 50 are rotatably arranged in the bearing seats installed inside the first cover 120 and the second cover 130. The lower frame body 20 includes a second outer shell 210. The end face of the second outer shell 210 facing away from the second discharge hopper 90 is an open face. A pair of opening and closing plates 220 are hinged inside the open face, and pull handles 230 are arranged inside the opening and closing plates.

[0042] To make an explanation, to ensure the stability and durability of the device, both the upper frame body 10 and the lower frame body 20 are made of high-strength metal materials and have good corrosion resistance. To further improve the working efficiency, the size and shape of the feed port can be set according to actual needs, so as to ensure that the rice evenly enters the milling component 50 and avoid the occurrence of blockage and uneven milling. In terms of maintenance, all vulnerable parts in this device, such as the milling component 50, the bearing seat and the separation component 70, are designed as quick-disassembly structures, which are convenient for users to perform daily cleaning and replacement.

[0043] With reference to the accompanying drawings of the specification Figures 1-9As shown, the driving component 40 includes a driving motor 410 and a belt tensioning component 420. The driving motor 410 is fixedly connected to the bottom of the second housing 210. The driving shaft of the driving motor 410 is rotationally connected to the milling component 50 through the belt tensioning component 420. The milling component 50 includes a rotating roller 510 and a first mesh 520. Both ends of the rotating roller 510 are rotatably arranged in the bearing seats installed inside the first housing 120 and the second housing 130, and are rotationally connected to the belt tensioning component 420. At least two first meshes 520 are provided and are in the shape of a curved panel. A plurality of through holes are formed on the surface of the first mesh 520. Among them, the two first meshes 520 are arranged in a surrounding manner inside the first housing 110. Both ends of the first mesh 520 are fixedly connected to the inner bottom surfaces of the first housing 120 and the second housing 130 respectively. A plurality of roller rings 530 for conveying materials and a plurality of roller bars 540 for milling are respectively provided on the surface of the rotating roller 510 near the feed inlet and the surface away from the feed inlet. The roller rings 530 are fixedly arranged in rows around the surface of the rotating roller 510. The roller bars 540 are fixedly bent in a circumferential and integral manner on the surface of the rotating roller 510, and the roller bars 540 are in the shape of blades.

[0044] It should be noted that the blade-shaped design of the roller bars 540 can effectively mill the rice, while ensuring the uniformity and efficiency during the milling process. To further improve the milling effect, the arrangement and spacing of the roller bars 540 can be adjusted according to different types of rice to adapt to paddy with different sizes and hardness. In addition, to ensure the stable operation of the milling component 50, high-quality bearings are used for the bearing seats at both ends of the rotating roller 510 to reduce wear and noise and extend the service life of the equipment.

[0045] It is worth noting that a collection trough can be provided below the milling component 50 for collecting the preliminarily milled rice. The bottom of the collection trough can be provided with an adjustable baffle according to actual needs. The operator can adjust the angle of the baffle as needed to control the flow rate of the rice and ensure that the rice evenly enters the diversion pipe 60.

[0046] Combined with the attached drawings of the specification Figures 1-9 As shown, the diversion pipe 60 is a flexible hose, the separation component 70 is a centrifugal fan. One end of the diversion pipe 60 is communicated with the air inlet of the centrifugal fan. The second discharge hopper 90 is communicated with the air outlet of the centrifugal fan. The first discharge port is opened at the top of the first housing 110. An inlet hopper 30 is arranged outside the first discharge port, and the inlet hopper 30 is in the shape of a funnel.

[0047] It should be noted that the use of the centrifugal fan can provide strong air flow to ensure the separation effect of rice bran and white rice. Among them, the flexible design of the diversion pipe 60 can effectively absorb the vibration generated during the operation of the equipment, reduce the impact on the entire device, and facilitate installation and maintenance at the same time. The length and bending angle of the diversion pipe 60 can be adjusted according to the actual space layout to ensure smooth material flow.

[0048] Furthermore, it is worth noting that the feed hopper 30 of the first discharge port is designed in a funnel shape, which can effectively guide the rice to enter the grinding component 50 evenly. Anti-slip patterns can also be provided on the inner wall of the feed hopper 30 according to actual needs to prevent the rice from sliding or jamming when entering the grinding component 50, and an adjustable gate can also be provided at the bottom of the feed hopper 30, and the operator can adjust the opening degree of the gate according to actual needs to control the flow rate of the rice.

[0049] The above are only the preferred embodiments of the present application and are not intended to limit the present application. For those skilled in the art, various changes and modifications can be made to the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included within the protection scope of the present application.
