[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figure 1-2 This utility model provides the following technical solution: a rice milling machine feed hopper, a main body 1, and a feeding cylinder 2 that is connected to the bottom of the main body 1. The brown rice inside the main body 1 can fall into the feeding cylinder 2 by gravity and enter the rice milling machine through the feeding cylinder 2. When the feeding cylinder 2 is blocked, a rotating cylinder 3 is rotatably connected inside the feeding cylinder 2. An auger blade 4 is fixedly connected inside the rotating cylinder 3. The rotation of the rotating cylinder 3 can drive the auger blade 4 to rotate, so that the auger blade 4 conveys the brown rice downward, thereby preventing the feeding cylinder 2 from being blocked. The auger blade 4 can extend into the interior of the main body 1, thereby improving the anti-blocking effect. A driving device 5 is provided on the main body 1 to drive the rotating cylinder 3 to rotate. The driving device 5 can drive the rotating cylinder 3 to rotate.

[0027] In a specific embodiment of this utility model, the rotating cylinder 3 is driven to rotate by the driving device 5, and the rotating cylinder 3 drives the auger blades 4 to rotate. When the material falls into the feeding cylinder 2, the rotation of the rotating cylinder 3 can prevent the feeding cylinder 2 from clogging, thereby making the anti-clogging effect of the device better.

[0028] Please see Figure 1 and Figure 3 The driving device 5 includes a driving component 51 fixedly installed on the main body 1. The output end of the driving component 51 is fixedly connected to a rotating shaft 52. When the driving component 51 rotates, it can drive the rotating shaft 52 to rotate. A gear 53 is fixedly connected on the rotating shaft 52. The rotation of the rotating shaft 52 can drive the gear 53 to rotate. A gear ring 54 that meshes with the gear 53 is provided on the rotating cylinder 3. The meshing of the gear 53 and the gear ring 54 can drive the rotating cylinder 3 to rotate through the gear ring 54. An opening groove 55 is provided on the feeding cylinder 2 to allow the gear 53 and the gear ring 54 to mesh. The opening groove 55 can be used for the meshing of the gear 53 and the gear ring 54.

[0029] Please see Figure 4 The inside of the feeding cylinder 2 is provided with a limiting groove 6 for limiting the up and down sliding of the rotating cylinder 3. The gear ring 54 rotates inside the limiting groove 6. By rotating inside the limiting groove 6, the up and down sliding of the rotating cylinder 3 can be limited, thereby preventing the rotating cylinder 3 from falling out of the inside of the feeding cylinder 2.

[0030] Preferably, the driving component 51 is a motor, which can be used to drive the rotating shaft 52 to rotate.

[0031] Please see Figure 2 and Figure 5 The main body 1 has an inclined first filter plate 7 inside. When brown rice enters the main body 1, it first falls onto the first filter plate 7. Because the first filter plate 7 is inclined, the brown rice slides on the surface of the first filter plate 7. Through the movement of the brown rice relative to the first filter plate 7, impurities such as stones inside the brown rice can be filtered. A second filter plate 8 is provided at the lower end of the first filter plate 7. The filtered impurities such as stones will slide onto the second filter plate 8. In addition, the brown rice that does not pass through the first filter plate and falls into the main body 1 will also fall onto the second filter plate 8. The second filter plate 8 slides horizontally on the main body 1. The driving device 5 is provided with a reciprocating component 9 that drives the second filter plate 8 to slide back and forth. The operation of the reciprocating component 9 can drive the second filter plate 8 to slide back and forth, thereby filtering the brown rice on the second filter plate 8. The main body 1 is provided with a cleaning structure 10 for cleaning the impurities such as stones on the second filter plate 8. Then, the filtered impurities such as stones can be cleaned by the cleaning mechanism 10.

[0032] Please see Figure 5 and Figure 6 The reciprocating assembly 9 includes an incomplete gear 91 fixedly connected to the rotating shaft 52. When the rotating shaft 52 rotates, it can drive the incomplete gear 91 to rotate. One side of the second filter plate 8 passes through the body 1 and is fixedly connected to the reciprocating frame 92. Both sides of the reciprocating frame 92 are provided with racks 93 that mesh with the incomplete gear 91. The incomplete gear 91 meshes with the racks 93 alternately. Through the alternating meshing of the incomplete gear 93 and the racks 93, the incomplete gear 93 can drive the reciprocating frame 92 to perform reciprocating motion.

[0033] Please see Figure 1 and Figure 6 The cleaning structure 10 includes two baffles 101 slidably connected to the second filter plate 8. The baffles 101 can slide inside the second filter plate 8, so that the baffles 101 can remove debris from the second filter plate 8 when sliding. The two baffles 101 are connected by a connecting post 102, so that the two baffles 101 can move synchronously. The body 1 is provided with a limiting block 103 for limiting the movement of the two baffles 101. One limiting block 103 is fixed to the body 1 and the other limiting block 103 is rotatably connected to the body 1. By setting the limiting block 103, the two baffles 101 can be limited inside the body 1. By rotating one of the limiting blocks 103 on the body 1, the baffle 101 can be pulled out from inside the body 1. When the baffle 101 is pulled out from inside the body, the debris on the second filter plate 8 can be cleaned.

[0034] Specifically, the discharge port of the feeding cylinder 2 is provided with an installation protrusion, which can be used to install the feeding cylinder 2 on the rice milling machine.
