Description

Technical Field

[0001] This utility model belongs to the field of rice processing technology, specifically relating to a high-efficiency rice hulling device for rice processing. Background Technology

[0002] A rice huller is a grain processing machine that removes the husk from paddy rice to produce brown rice. It plays an indispensable role in modern rice processing. Its main function is to remove the outer shell, impurities, and germ from rice. The rice huller uses high-speed rotation or vibration. Through the friction, grinding, and bumping action of the screen and friction wheels, the rice is continuously rubbed against the screen, removing the outer shell and impurities. The rice huller is mainly composed of a hopper feeding device, a machine head device, a husk separation chamber, a gearbox, and a frame. It can remove the outer shell of paddy rice, reduce rice grain breakage and surface damage, and keep the brown rice as intact as possible.

[0003] For example, Chinese Patent Publication No. CN111974486A discloses a rice hulling device for rice processing, including a frame, a hulling box, a fast roller, and a slow roller. A feed hopper is installed at the top of the hulling box. The interior of the hulling box contains a collection chamber and a husk separation chamber. The top of the collection chamber is connected to the feed hopper. A conveying pipe is hinged to the bottom of the collection chamber, and the conveying pipe is connected to the interior of the collection chamber. A fast roller and a slow roller are installed below the outlet of the conveying pipe. The rubber roller is driven by a belt to the slow rubber roller, and the fast rubber roller is fixed to the drive shaft. The inside of the rice husk separation chamber is equipped with a broken rice collection bin, a polished rice screening structure and an air duct. The outer wall of the rice husk separation chamber is equipped with a broken rice discharge bin, a polished rice discharge bin, a rice bran discharge bin and an electrical control box. This invention can separate polished rice and broken rice, which is beneficial to improving the quality of rice processing. At the same time, it is easy to adjust the feeding angle between the fast rubber roller and the slow rubber roller, which can more fully dehull the rice.

[0004] In most of the rice hulling devices mentioned above and in the prior art, the feed flow rate at the feed inlet is limited, often resulting in rice clogging at the feed inlet and preventing the rice from smoothly entering the rice huller. This requires constant manual clearing, increasing the workload of workers and affecting the overall processing efficiency.

[0005] Therefore, there is a need for a high-efficiency rice hulling device to solve the problems mentioned in the background art. Utility Model Content

[0025] The present invention will be further described below with reference to the embodiments.

[0026] Please see Figure 1-6This utility model provides a high-efficiency rice hulling device, including a rice huller body 4, a discharge box 3 at the top of the rice huller body 4, a feeding hopper 5 fixed at the top of the discharge box 3 and communicating with the inside of the discharge box 3, a support rod 8 fixed between the feeding hopper 5 and the rice huller body 4, a discharge port at the bottom of the discharge box 3, and a feeding port 7 at the top of the rice huller body 4 located directly below the discharge port of the discharge box 3. An arc-shaped screen plate 13 is fixed on the discharge port at the bottom of the discharge box 3. A drive motor 12 is fixed to the outer wall. An agitator 1, connected to the drive motor 12, is installed inside the discharge box 3. A cleaning assembly 2 is installed at one end of the discharge box 3. In use, rice is poured into the hopper 5, and the rice falls into the discharge box 3. The drive motor 12 drives the agitator 1, which agitates the rice inside the discharge box 3, increasing its flowability and facilitating discharge. Inside box 3, rice grains are continuously screened by the arc-shaped screen plate 13 and fall into the feed inlet 7, thus entering the stirring component 1 for hulling processing. The stirring component 1 continuously agitates the rice inside the discharge box 3, preventing the discharge outlet of box 3 from being blocked by rice, making the processing smoother and more efficient, eliminating the need for constant manual unblocking, saving manpower, and ensuring overall processing efficiency. At the same time, the arc-shaped screen plate 13 screens out larger stones, soil clods, and other impurities in the rice. To prevent larger impurities from falling into the agitation component 1 and improve the purity of rice hulling processing, after all the rice in the hopper 5 and discharge box 3 has fallen out, the air pump 6 is started to work. The air pump 6 delivers airflow to the cleaning component 2, and the cleaning component 2 blows the airflow evenly and finely onto the arc-shaped screen plate 13, thereby blowing away the larger solid impurities screened on the arc-shaped screen plate 13, completing the efficient cleaning of impurities, and effectively improving the cleaning efficiency and convenience.

[0027] Further as Figure 2 , Figure 4 and Figure 5As shown, it is worth noting that the agitation assembly 1 includes a shaft 101 disposed inside the discharge box 3. Both ends of the shaft 101 are rotatably connected to the side wall of the discharge box 3. An end shaft 105, coaxially arranged with the shaft 101, is fixed to one end of the shaft 101. A first gear 106 located outside the discharge box 3 is fixed to the end shaft 105. A second gear 107, meshing with the first gear 106, is fixed to the output end of the drive motor 12. Agitation rods 102 are fixed to the side of the shaft 101. Multiple agitation rods 102 are arranged equidistantly. During operation, the agitation assembly 1 is activated by the drive motor 12. The output of the motor 12 drives the second gear 107 to rotate, which in turn drives the end shaft 105 and shaft 101 to rotate through the cooperation of the second gear 107 and the first gear 106. This causes the multiple stirring rods 102 on the shaft 101 to continuously stir the rice inside the discharge box 3, increasing the flowability of the rice inside the discharge box 3. This allows the rice grains inside the discharge box 3 to be continuously screened by the arc-shaped screen plate 13 and fall into the feed inlet 7, preventing the discharge outlet of the discharge box 3 from being blocked by rice. This makes the processing smoother and more efficient, saves manpower, and ensures overall processing efficiency by eliminating the need for constant unblocking.

[0028] Further as Figure 4 and Figure 5 As shown, it is worth noting that an end-connecting rod 103 is fixed to one end of the multiple stirring rods 102 away from the shaft 101. The side of the end-connecting rod 103 is fixed with densely distributed cleaning bristles 104 that contact the arc-shaped screen plate 13. In actual operation, as the stirring rods 102 rotate, they drive the end-connecting rods 103 to rotate synchronously. This allows the cleaning bristles 104 on the end-connecting rods 103 to continuously clean the screen holes on the arc-shaped screen plate 13, preventing the screen holes from being blocked and ensuring the smooth flow of rice grains.

[0029] Further as Figure 2 , Figure 3 and Figure 6As shown, it is worth noting that the cleaning component 2 includes a blower seat 201 fixed to one end of the discharge box 3. The blower seat 201 has an internal cavity. An air pump 6 is fixed to the outer wall of the discharge box 3. An air supply pipe 203 is fixed to the output end of the air pump 6. The end of the air supply pipe 203 away from the air pump 6 communicates with the internal cavity of the blower seat 201. An air outlet 202 is provided on the side of the blower seat 201, located inside the discharge box 3 and communicating with the internal cavity of the blower seat 201. Multiple air outlets 202 are provided and are equidistantly distributed. A protective net cover is fixed to the outer wall of the blower seat 201, covering the air outlets 202. When the hopper 5... After all the rice grains inside the discharge box 3 fall into the feed inlet 7 for feeding, the cover plate 10 is opened, thereby opening the impurity discharge port 9. The air pump 6 is started to work, and the air pump 6 delivers airflow through the air pipe 203 to the blower seat 201. The airflow is then blown evenly and finely onto the arc-shaped screen plate 13 through multiple air outlets 202. The airflow blows out the larger solid impurities screened on the arc-shaped screen plate 13 through the impurity discharge port 9, completing the efficient cleaning of impurities and effectively improving cleaning efficiency and convenience. The hole size on the protective net is smaller than the size of the smallest rice grain, and the protective net prevents rice grains from entering the air outlet 202.

[0030] Further as Figure 2 As shown, it is worth noting that a discharge port 9 is provided on the side wall of the discharge box 3 away from the blower seat 201. A cover plate 10 is hinged inside the discharge port 9, and a handle 11 is fixed on the outer side wall of the cover plate 10. In actual operation, the cover plate 10 can be opened and closed conveniently by using the handle 11, which facilitates operation.

[0031] This solution includes the following working process: Rice is poured into the hopper 5, and the rice in the hopper 5 falls into the discharge box 3. The output of the drive motor 12 drives the second gear 107 to rotate. The second gear 107, in conjunction with the first gear 106, drives the end shaft 105 and shaft 101 to rotate. This, in turn, causes multiple agitators 102 on the shaft 101 to continuously agitate the rice inside the discharge box 3, increasing the flowability of the rice and allowing the rice grains inside the discharge box 3 to continuously pass through an arc-shaped... The rice grains in the sieve plate 13 are screened and fall into the feed inlet 7. After all the rice grains in the hopper 5 and the discharge box 3 have fallen into the feed inlet 7, the cover plate 10 is opened to open the discharge port 9. The air pump 6 is started to work. The air pump 6 delivers airflow through the air pipe 203 to the blower seat 201. The airflow is then blown evenly and finely onto the arc-shaped sieve plate 13 through multiple air outlets 202. The larger solid impurities screened on the arc-shaped sieve plate 13 are blown out through the discharge port 9 by the airflow, thus cleaning the impurities.

[0032] Further as Figure 4 and Figure 6 As shown, it is worth noting that the blower seat 201 is located at the bottom of the discharge box 3, and the air outlet 202 is set at an angle downwards. In actual operation, the airflow is fully blown out to the side of the arc-shaped screen plate 13 through the air outlet 202 located at the bottom of the discharge box 3 and at an angle downwards, thereby improving the cleaning effect of the airflow on impurities.

[0033] In summary: The agitator 1 continuously agitates the rice inside the discharge box 3, preventing the discharge port of the discharge box 3 from being blocked by rice, making the processing smoother and more efficient, saving manpower and ensuring overall processing efficiency. At the same time, the arc-shaped screen plate 13 screens out larger stones, soil clods and other impurities in the rice, preventing larger impurities from falling into the agitator 1, thus improving the purity of the rice hulled rice. After all the rice in the hopper 5 and the discharge box 3 has been discharged, the air pump 6 is started to work. The air pump 6 delivers airflow to the cleaning component 2, and the cleaning component 2 blows the airflow evenly and finely onto the arc-shaped screen plate 13, thereby blowing out the larger solid impurities screened on the arc-shaped screen plate 13, completing the efficient cleaning of impurities, effectively improving cleaning efficiency and convenience.

[0034] The air pump 6 and drive motor 12 can be purchased from the market. The air pump 6 and drive motor 12 are equipped with power supplies. They are mature technologies in the field and have been fully disclosed. Therefore, they will not be described again in the specification.
