Description

Technical Field

[0001] The utility model relates to the technical field of rice milling equipment, and more specifically, to a rice milling machine for rice processing. Background Art

[0002] A rice mill is a specialized piece of machinery used for rice processing. It utilizes a series of sophisticated mechanical devices, including a feed hopper, milling rollers, screens, and fans, to hull, bran, and polish the rice, producing white, flavorful rice. During operation, rice enters the mill from the feed hopper and passes between high-speed rotating rollers. Pressure and friction between the rollers peel away the husks. Simultaneously, the internal screens and fans work together to separate impurities such as husks and bran, leaving clean rice for discharge through the outlet. The rice mill not only improves rice processing efficiency but also allows for flexible control of rice processing accuracy and yield by adjusting parameters such as the gap and speed of the milling rollers to meet the needs of diverse consumers.

[0003] In the traditional rice processing industry, rice mills are core equipment, and their performance directly determines the processing quality and production efficiency of rice. However, traditional rice mills have inherent design flaws, which are particularly prominent when processing large quantities of brown rice. When a large amount of brown rice is poured into the rice mill at once, the mutual compression and friction between the brown rice grains can easily lead to overcrowding in the feed inlet or internal hopper, resulting in blockage of the discharge port.

[0027] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of them. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts are within the scope of protection of the present invention.

[0028] Example:

[0029] See also Figures 1-4 , a rice milling machine for rice processing, comprising:

[0030] A vertical rice milling machine body 1 is provided with a barrel 2 fixedly mounted on the top of the body 1. The barrel 2 is connected to the interior of the body 1. An inner hopper 4 is fixedly embedded in the barrel 2. An external connecting box 3 is fixedly connected to the outer surface of the barrel 2. A transmission circular plate 9 is rotatably connected to the inner wall of one side of the external connecting box 3.

[0031] An L-shaped connecting rod 6 slides through the inner wall of the barrel 2, the upper end of the L-shaped connecting rod 6 is fixedly connected to a conical plug 5, the conical plug 5 slides through the bottom inner wall of the inner hopper 4, one end of the L-shaped connecting rod 6 is fixedly connected to a lifting plate 8, the top of the lifting plate 8 is rotatably connected to a transmission rod 10, and the transmission rod 10 is rotatably connected to the transmission circular plate 9; and

[0032] The deceleration drive assembly is arranged on an outer surface of one side of the external connection box 3 .

[0033] In a specific embodiment of the present invention, a vertical rice milling machine body 1 is a common mechanical device for peeling and whitening brown rice on the market. Its model and specifications are selected according to actual conditions. In actual use, a large amount of brown rice is poured into the interior of the barrel 2. Because the conical plug 5 blocks the bottom opening of the inner hopper 4, the brown rice cannot pass through the inner hopper 4, and cannot enter the interior of the vertical rice milling machine body 1 through the discharge port of the barrel 2. When the brown rice is to be peeled and whitened, the transmission circular plate 9 is driven to rotate by the reduction drive component, so that the transmission circular plate 9 drives the lifting plate 8 to perform a reciprocating lifting motion through the transmission rod 10. The lifting plate 8 drives the conical plug 5 to perform a reciprocating lifting motion through the L-shaped connecting rod 6. When the conical plug 5 rises, its tapered part will enter The brown rice is loosened by pushing it into the inner hopper 4. When the conical plug 5 descends, a gap of appropriate size will appear at the bottom opening of the inner hopper 4 to allow some brown rice to pass through. The brown rice then enters the interior of the vertical rice milling machine body 1 through the discharge port of the barrel 2 for peeling and whitening. Compared with the traditional rice milling machine, when a large amount of brown rice is poured in at one time, the discharge port is prone to be blocked due to the dense accumulation of brown rice. When rising, the conical plug 5 can loosen the brown rice in the inner hopper 4 to prevent it from agglomerating or compacting. When descending, the size of the bottom opening is controlled to allow an appropriate amount of brown rice to pass through, thereby avoiding the occurrence of blockage and achieving uniform discharge of brown rice, ensuring the continuity and stability of the rice milling process, helping to improve the quality of rice milling and reduce the broken rice rate and the production of defective products.

[0034] Specifically, the reduction drive assembly includes a side connection box 12, a driving gear 13 and a driven gear 14. The side connection box 12 is fixedly connected to the outer surface of one side of the external connection box 3. The driving gear 13 and the driven gear 14 are both rotatably connected between the external connection box 3 and the side connection box 12. The driving gear 13 is meshed with the driven gear 14, and the driven gear 14 is fixedly connected to the transmission circular plate 9.

[0035] In this embodiment, the number of teeth and the radius size of the driving gear 13 are smaller than those of the driven gear 14. The driving gear 13 drives the driven gear 14 to rotate, so that the driven gear 14 drives the transmission circular plate 9 to rotate at a slower speed, reducing unnecessary impact and vibration and increasing the stability of the overall structure.

[0036] Specifically, the reduction drive assembly further includes a drive motor 7 , which is fixedly mounted on an outer surface of one side of the side connection box 12 , and an output end of the drive motor 7 is fixedly connected to the driving gear 13 .

[0037] In this embodiment, the driving gear 13 can be driven to rotate by controlling the driving motor 7 to start.

[0038] Specifically, two limiting rods 11 are fixedly connected between the upper and lower inner walls of the external connection box 3 , and the lifting plate 8 is slidably sleeved on the two limiting rods 11 .

[0039] In this embodiment, the two limiting rods 11 allow the lifting plate 8 to only be able to move up and down, and remain stable during the movement.

[0040] Specifically, the two limiting rods 11 are respectively located on both sides of the transmission circular plate 9 .

[0041] In this embodiment, the two limiting rods 11 will not come into contact with the transmission circular plate 9 and the transmission rod 10 , thereby preventing the limiting rods 11 from affecting the normal movement of the transmission circular plate 9 and the transmission rod 10 .

[0042] Specifically, the two limiting rods 11 are both made of stainless steel.

[0043] In this embodiment, the limiting rod 11 is made of stainless steel, which has a smoother surface, facilitates the up and down sliding of the lifting plate 8, and has high strength and durability.

[0044] Working principle: In actual use, a large amount of brown rice is poured into the interior of the barrel 2. When the brown rice needs to be peeled and whitened, the driving motor 7 is controlled to drive the active gear 13 to rotate, so that the driven gear 14 drives the transmission circular plate 9 to rotate, so that the transmission circular plate 9 drives the lifting plate 8 to make a reciprocating lifting movement through the transmission rod 10, and the lifting plate 8 drives the conical plug 5 to make a reciprocating lifting movement through the L-shaped connecting rod 6. When the conical plug 5 rises, its tapered part will enter the interior of the inner hopper 4 to loosen the brown rice. When the conical plug 5 falls, the bottom opening of the inner hopper 4 will leak a gap of appropriate size to allow some brown rice to pass through, and then enter the interior of the vertical rice milling machine body 1 through the discharge port of the barrel 2 for peeling and whitening. Compared with traditional rice mills, When a large amount of brown rice is poured in at one time, the problem of clogging of the feed port is easy to occur due to the dense accumulation of brown rice. The conical plug 5 can loosen the brown rice in the inner hopper 4 when rising to prevent it from clumping or compacting; when descending, it controls the size of the bottom opening to allow an appropriate amount of brown rice to pass through, thereby avoiding the occurrence of clogging and achieving uniform feeding of brown rice, ensuring the continuity and stability of the rice milling process, helping to improve the quality of rice milling, and reducing the broken rice rate and the production of defective products. The control method of the present invention is to control the switch by manually starting and stopping. The wiring diagram of the power element and the provision of power supply are common knowledge in this field, and the present invention is mainly used to protect the mechanical device, so the present invention will no longer explain the control method and wiring arrangement in detail.

[0045] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and improved ideas of the present invention, which should be covered by the protection scope of the present invention.
