[0033] The following will be combined with the drawings in the utility model to clearly and completely describe the technical solution in the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0034] See also Figure 1-Figure 7 , the utility model provides a technical solution:

[0035] A rice processing hulling device comprises a casing 1, a feeding port 10 is arranged near the left edge of the top surface of the casing 1, a through opening 11 is arranged near the lower end of the casing 1, and two rollers 2 which are parallel to each other and in opposite directions are inserted and rotated in the casing 1 through bearings, and the rollers 2 are used for transporting and processing rice. Since the functions of the spiral groove 20 and the rice knife 21 are inconsistent, in order to ensure the smoothness of the secondary processing of the rice, the left and right ends of the two rollers 2 are reversed, and the rollers 2 are rotated and rotated. A spiral groove 20 for feeding is provided on the arc side surface at one end, and a number of radially distributed rice knives 21 are welded and fixed on the arc side surface at the other end of the roller 2. The rice knives 21 husk the rice by impact and friction. A rice sieve 3 is provided on the periphery of the two rollers 2. The rice sieve 3 is used to screen and separate rice bran from rice grains. An air duct 4 for absorbing rice bran is fixedly inserted between the two rollers 2 on the left side wall of the casing 1. The air duct 4 is externally connected to a blower 6. A motor 5 for driving the two rollers 2 to rotate is provided on the right outer wall of the casing 1 to drive the rollers 2 to operate.

[0036] In this embodiment, the feed port 10 is in the shape of a chamfered cone, which is convenient for loading rice into the casing 1 without clogging. A partition 13 is fixed to the inner wall of the casing 1 above the opening by bolts to prevent rice bran from flying out of the casing 1 to avoid causing a large amount of dust. The partition 13 is provided with a rice grain outlet 11 at a position corresponding to the upper and lower positions of the feed port 10. The rice grain outlet 11 is arranged in the casing 1 to prevent external dust from affecting the rice grains.

[0037] In this embodiment, the interior of the roller 2 is hollow to enhance heat dissipation, and the spiral groove 20 spirally extends and approaches the rice cutter 21 along the central axis of the roller 2 to ensure that the rice can be transported to the rice cutter 21.

[0038] In this embodiment, the arc side surfaces of the two rollers 2 extending out of the left side wall of the casing 1 are provided with belt grooves corresponding to the upper and lower positions. The two belt grooves are connected by a belt 50 to reduce materials and resources.

[0039] In this embodiment, the circular end surface of the roller 2 near the bottom end of the housing 1 is coaxially fixed to the output shaft of the motor 5, and the motor 5 is fixed to the tripod by bolts.

[0040] In this embodiment, the rice sieve 3 is composed of two semicircular rice sieves 30 connected together and fixed by bolts, which is convenient for the rice sieve 3 to be disassembled and installed in the casing 1, and the arc side wall of the rice sieve 30 is provided with a plurality of evenly distributed fine holes for screening rice bran and rice grains. Two support rods 12 for installing the rice sieve 3 are welded and fixed on the left and right inner walls of the casing 1, and the intersection of the two rice sieves 30 of the rice sieve 3 is fixed to the support rod 12 at the corresponding position by bolts to enhance firmness.

[0041] In this embodiment, the two rice sieves 3 are interconnected by a pipe 7 near the inner wall of the right end of the casing 1, and the feed port 10 and the upper rice sieve 3, and the rice grain outlet 11 and the lower rice sieve 3 are all connected by the pipe 7. The pipe 7 is used to transport rice to avoid loss of rice.

[0042] In this embodiment, one end of the air duct 4 away from the casing 1 is fixedly plugged into the air inlet of the blower 6 to provide power for absorbing rice bran, and a rice bran outlet 60 is fixedly plugged into the air outlet of the blower 6 to facilitate the collection of rice bran. The motor 5 and the blower 6 are electrically connected to an external power supply through a wire.

[0043] Finally, it should be noted that the motor 5, blower 6 and other components involved in the present invention are all universal standard parts or components known to technical personnel in this field. Their structures and principles are known to technical personnel through technical manuals or through conventional experimental methods. In the idle space of this device, all the above-mentioned electrical components, which refer to power elements, electrical components, and compatible controllers and power supplies, are connected through wires. The specific connection means should refer to the working principle of the present invention. The electrical connection between each electrical component is completed in a sequential working order, and the detailed connection means are all well-known technologies in the field.

[0044] When the rice processing hulling device of the utility model is used, the motor 5 and the blower 6 are first turned on, and the rice is poured into the casing 1 from the feed port 10. The rice enters between the upper roller 2 and the rice sieve 3 through the pipeline 7, and is transported to the rice cutter 21 through the spiral groove 20 on the surface of the roller 2. The rice is hit and rubbed by the high-speed rotation of the rice cutter 21, so that the rice bran is removed from the rice and precipitated through the rice sieve 3. At the same time, the rice bran is light in weight and is sucked out of the casing 1 through the air duct 4 through the blower 6 and discharged from the rice bran outlet 60, while the rice grains continue to be transported to the lower roller 2 through the pipeline 7, and are processed through the same steps. Finally, the rice grains are poured into the outside of the casing 1 from the rice grain outlet 11.

[0045] The above shows and describes the basic principle, main features and advantages of the present embodiment of the utility model. Those skilled in the art should understand that the present utility model is not limited by the above embodiment. The above embodiment and description are only preferred examples of the present utility model and are not used to limit the present utility model.
