Abstract
Description
Technical Field
[0001] This utility model relates to the field of rice processing technology, specifically a rice milling machine for processing rice products. Background Technology
[0002] Rice is one of the most important food crops for mankind, especially in Asia and Africa, where it is the staple food for billions of people. It has a long history of cultivation, diverse varieties, and is closely related to the development of human civilization. It can be classified into indica rice, japonica rice, and glutinous rice according to the type of rice, and into brown rice, white rice, and germ rice according to the degree of processing.
[0003] In daily life, rice products are also extremely diverse, such as rice noodles, rice cakes, and rice wine. The production of these products often requires grinding rice into powder first. In order to make the finished product more delicate and smooth, reduce dust, and retain more nutrients and flavor, the rice is often soaked before grinding.
[0004] However, when traditional rice milling machines process soaked rice, the surface tension of the water on the rice grains causes adjacent grains to adhere to each other. At the same time, the rice grains also stick to the surface of the feed inlet due to moisture, causing stagnation. If too much material is poured in at once, it is very likely to cause blockage. At this time, workers need to use tools to clear the blockage, which not only increases the workload, but also poses a risk of workers touching the blades and getting injured. Therefore, a rice milling machine for processing rice products is proposed to address the above problems. Utility Model Content

[0030] 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.
[0031] Example 1
[0032] Please see Figure 1-4 As shown, a rice milling machine for processing rice products includes a base frame 1 and a body 2, with the body 2 mounted on the base frame 1 by fixing bolts;
[0033] Motor 7 is used to drive the grinding blades inside the body 2, and the connection between motor 7 and body 2 is controlled by a belt.
[0034] The surface of the main body 2 is provided with a feeding port 3 and a discharging port 11;
[0035] A connecting rod 6 is slidably connected to the surface of the base frame 1 via a spring. A main shaft 5 is fixedly connected to the surface of the connecting rod 6. A buffer pad is fixedly connected to the surface of the main shaft 5.
[0036] The main spindle 5 has a cavity inside, and the secondary spindle 51 is slidably connected to the cavity by a spring.
[0037] Motor 2 9 is fixedly connected to the base frame 1 by bolts. A rotating ring 13 is fixedly connected to the surface of the output shaft of motor 2 9. A toggle block 12 is fixedly connected to the surface of the rotating ring 13. Several toggle blocks 12 are provided and are evenly distributed.
[0038] The connecting rod 6 is L-shaped, and the surface of the lever 12 is arc-shaped;
[0039] A rotating wheel 15 is rotatably connected to the short arm end surface of the connecting rod 6, and the rotating wheel 15 is in contact with the arc surface of the lever block 12.
[0040] During operation, rice to be ground is poured into the feed inlet 3. Motor 7 drives the blades inside the main body 2 to pulverize the rice. Simultaneously, motor 9 is activated, causing the rotating ring 13 on the output shaft surface to rotate. As the ring 13 rotates, it drives the paddle block 12 to rotate. The arc surface of the paddle block 12 then presses against the rotating wheel 15, causing the connecting rod 6 to move downwards. Simultaneously, it compresses the spring, generating elastic force. When the rotating wheel 15 passes the paddle block 12, because the paddle block 12 is approximately a right triangle, the connecting rod 6 returns to its original position under the action of the spring. This causes the connecting rod 6 to spring upwards, thereby causing the main shaft 5 to impact the side wall of the feed inlet 3. At the moment the main shaft 5 springs up, the secondary shaft 51 will remain stationary due to inertia. When the main shaft 5 hits the feed port 3, the secondary shaft 51 will achieve a secondary impact under the action of the spring, thereby improving the vibration effect. The vibration generated by the impact between the main shaft 5 and the secondary shaft 51 can shake off the stagnant rice, thus preventing it from sticking to the surface of the feed port 3 of the mill and accumulating, causing blockage. This also simplifies the operation of the staff to clear the blockage with tools, reducing the workload and avoiding the possibility of hands touching the blades and causing injury. Finally, the buffer pad can protect the feed port 3 to prevent damage caused by long-term impact.
[0041] A bracket 8 is fixedly connected to the surface of the base frame 1. The connecting rod 6 is slidably connected through the slide rod, which is used to reinforce the connecting rod 6. During operation, the connecting rod 6 is reinforced by the bracket 8 to prevent left and right swaying when the connecting rod 6 slides up and down. At the same time, it can also further position the sliding direction of the connecting rod 6 to avoid angular deviation, which would cause the spindle 5 to tilt when it is impacted.
[0042] Motor 29 is a dual-shaft motor with a reducer. There are also two main shafts 5, located below the feed inlet 3 and the discharge outlet 11 respectively. During operation, the dual-shaft motor and the reducer can clean the feed inlet 3 and the discharge outlet 11 at the same time, avoiding the situation where the crushed rice flour is stuck in the discharge outlet 11. The reducer can reduce the speed of the rotating ring 13, thereby reducing the impact frequency of the main shaft 5 and further extending the service life of the feed inlet 3.
[0043] Example 2
[0044] Please see Figure 5-6 As shown in the comparison with Embodiment 1, as another embodiment of this utility model, the second motor 9 is a single-shaft geared motor. The main magnetic block 17 is detachably installed on the output shaft of the motor through a nut. A collar 21 is fixedly connected to the surface of the discharge port 11. A screen frame 19 is slidably installed inside the collar 21. The bottom surface of the screen frame 19 is a mesh. A threaded rod 23 is movably connected to the surface of the collar 21 through a spring. A fixing rod 22 is fixedly connected to the surface of the screen frame 19. One end of the fixing rod 22 passes through the collar 21 and is slidably connected. The end of the threaded rod 23 is threadedly connected to the fixing rod 22. A secondary magnetic block 18 is fixedly connected to the surface of the screen frame 19.
[0045] During operation, when grinding dried rice, the dried rice grains may not be ground completely. In this case, the rice needs to be sieved and ground a second time. Motor 9 is then started, causing the main magnetic block 17 to rotate. When the main magnetic block 17 rotates to the position of the auxiliary magnetic block 18, the principle of opposite phases attracting each other pulls the auxiliary magnetic block 18 towards the main magnetic block 17. Simultaneously, this pulls the fixing rod 22, which in turn moves the threaded rod 23, compressing the spring and generating elastic force. Once the main magnetic block 17 and the auxiliary magnetic block 18 separate, the sieve frame 19 returns to its original position. The rice flour can be sieved by the reciprocating motion of the sieve frame 19, thereby removing the incompletely crushed rice particles. When the rice flour particles stored in the sieve frame 19 reach a certain amount, the main magnetic block 17 can be removed by disassembling the nut, and then the sieve frame 19 can be removed by releasing the threaded rod 23. The sieve frame 19 can then be removed, and the incompletely crushed rice particles can be mixed with the unground rice for secondary grinding. The design of the sieve frame 19 can sieve the ground rice flour, thereby ensuring the fineness of the rice flour and improving the processing quality of the rice flour.
[0046] The opening diameter of the screen frame 19 is larger than the inner diameter of the discharge port 11. A guide plate 16 is fixedly connected to the inner wall of the discharge port 11. A rubber ring is fixedly connected to the surface of the guide plate 16. Several main magnetic blocks 17 are provided. The rubber ring extends into the screen frame 19, and the bottom surface of the screen frame 19 is arc-shaped.
[0047] During operation, the opening diameter of the sieve frame 19 is larger than the inner diameter of the discharge port 11. At the same time, the guide plate 16 with a rubber ring can prevent excess rice flour from falling into the gap of the collar 21. Over time, this can cause the assembly of the sieve frame 19 to deviate. The arc shape of the bottom surface of the sieve frame 19 can achieve a gathering effect, guiding the rice flour to the middle position of the sieve frame 19 for better screening.
