[0002] A rice milling machine is a device that automatically mills rice. It is easy to use and can provide people with refined rice with better grain size and quality. There are three main types of small rice milling machines in my country: separate rice milling machines, rice hulling and milling combined rice milling machines, and air-jet rice milling machines.

[0003] Patent document CN220634456U discloses a grain dehulling and rice milling machine, including a rice milling machine body, a housing, a collection tray, a feed hopper, a bottom plate, and a discharge hopper. The rice milling machine body includes the housing, collection tray, feed hopper, bottom plate, and discharge hopper. The housing and discharge hopper are respectively arranged on both sides of the rice milling machine body. The collection tray is arranged on the front side of the rice milling machine body, which can reduce dust splashing at the feed hopper and fix the rice milling machine body on a flat surface, making it easy to fix. Different mounting plate heights can be adjusted, thereby fixing the rice milling machine body on uneven surfaces and facilitating the movement of the rice milling machine body.

[0004] However, the aforementioned grain dehulling and rice milling machine does not remove larger impurities from the grain before processing, which affects the service life of the internal parts and the overall processing effect. In addition, the dehulling speed is slow and the grain husks are not collected, which increases the labor cost. Therefore, we propose a grain dehulling and rice milling machine to solve the above problems. Utility Model Content

[0045] Specifically, guide blocks 17 are fixedly connected to both sides of the inside of the box 6, and a shelling box 18 is fixedly connected inside the box 6. A sanding roller 20 is rotatably connected inside the shelling box 18, and the shelling box 18 and the guide blocks 17 cooperate with each other.

[0046] Specifically, a peeling sieve 19 is fixedly connected inside the hulling box 18, a rice milling box is fixedly connected inside the box body 6, a baffle 21 is fixedly connected inside the rice milling box, and a cleaning box 9 is fixedly connected to one side of the outer side of the box body 6.

[0047] Specifically, the cleaning box 9 and the baffle 21 cooperate with each other, and a cover plate 10 is rotatably connected to one side of the cleaning box 9, and a handle 11 is fixedly connected to one side of the cover plate 10, and a straight plate is slidably connected to one side of the screening box 14.

[0048] Specifically, the rice milling box has two rice milling rollers 23 rotatably connected inside, and the two rice milling rollers 23 cooperate with each other. The rice milling box also has a secondary screen 22 fixedly connected inside, and the secondary screen 22 cooperates with the baffle 21.

[0049] Specifically, the output end of the motor 8 is fixedly connected to the sanding roller 20, and two rotating shafts 24 are fixedly connected inside the housing 6. The rotating shafts 24 are fixedly connected to the rice milling roller 23. One end of the sanding roller 20 and one of the two rotating shafts 24 is fixedly connected to a main pulley 25. The two main pulleys 25 are driven by the same main belt 26. A gear 27 is fixedly connected to one side of the rotating shaft 24. The two gears 27 mesh with each other. A rotating rod 28 is rotatably connected inside the housing 6. One end of the rotating rod 28 is fixedly connected to a fan blade 29. The fan blade 29 cooperates with the baffle 21. One end of the rotating rod 28 and one of the two rotating shafts 24 is fixedly connected to a secondary pulley 30. The two secondary pulleys 30 are driven by the same secondary belt 31.

[0050] The implementation principle of a grain dehulling and rice milling machine according to an embodiment of this application is as follows: When the device is needed, it is moved to a designated position by roller 2, and then the turntable 5 is rotated. The turntable 5 drives the stud 3 to rotate, and the stud 3 moves along the thread direction in the base plate 1, so that the pad 4 contacts the ground, thereby fixing the device in the designated position. Then, the grain is put into the screening box 14 through the feed pipe 7. The cylinder is started, and the cylinder drives the screening box 14 to slide back and forth along the sliding box 12, so that the grain in the screening box 14 is screened by the main screen 15, and the grain and larger impurities are screened out. The screened grain falls onto the guide block 17 through the screen plate 16, and then falls into the dehulling box 18 through the guide block 17. The motor 8 is started, and the output end of the motor 8 drives the sand roller 20 to rotate. The sand roller 20 causes the grain to rub against the dehulling box 19, thereby separating the grain husk from the grain. The motor 8 drives the sand roller 20 to rotate. When rotating, the main pulley 25 is also driven to rotate. The main pulley 25 drives the main belt 26, which in turn drives the corresponding shaft 24 to rotate. The shaft 24 drives the gear 27 to rotate. The gear 27 meshes with another gear 27 to rotate, causing the two rice milling rollers 23 to rotate in opposite directions. This crushes the grain that falls into the rice milling box, turning it into broken rice. The broken rice and grain husks fall onto the secondary screen 22. The broken rice falls through the secondary screen 22, while the grain husks remain on it. When the shaft 24 drives the rice milling rollers 23 to rotate, it also drives the secondary pulley 30 to rotate. The secondary pulley 30 drives the secondary belt 31, which in turn drives the rotating rod 28 to rotate, causing the fan blades 29 to rotate. The fan blades 29 suck the grain husks into the cleaning box 9 for storage through the baffle 21. After a certain period of time, the cover 10 is opened to clean the cleaning box 9, thus completing the work.

[0051] Example 2

[0052] The difference between this embodiment and embodiment one is that a mating plate is rotatably connected to one side of the feed pipe 7. When the grain enters the device, the mating plate is rotated to seal the feed pipe 7, thus preventing the dust generated during the operation of the device from affecting the surrounding environment.

[0053] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
