Description

Technical Field

[0002] In the grain processing industry, rice milling and polishing are key steps in transforming paddy into high-quality finished rice. Milling aims to remove the outer husk of the paddy to reveal the brown rice, while polishing further polishes the surface of the brown rice, improving the smoothness and appearance of the rice grains. At the same time, it can also effectively reduce the broken rice rate and improve the taste and storage performance of rice.

[0003] The vertical sand roller rice milling and polishing integrated machine is a specialized piece of equipment for rice processing. With its vertical structure design, it integrates rice milling and polishing functions into one unit, offering advantages such as small footprint and high processing efficiency. This equipment achieves rice milling and dehulling through the high-speed rotation of the sand roller, and uses the polishing roller to finely grind the rice grains. It can efficiently complete the conversion from paddy to finished rice in a continuous processing flow, and is widely used in the grain processing industry.

[0004] However, existing vertical sand roller rice milling and polishing integrated machines achieve rice milling and polishing through the rotation of sand rollers and polishing rollers. They can quickly process large quantities of rice and improve processing efficiency. However, since the rice milling and polishing areas of traditional equipment are relatively independent, material is prone to blockage during transmission. Furthermore, they lack effective impurity separation devices and rely solely on simple screen filtration, making it difficult to completely remove rice bran, broken rice, and impurities generated during the rice milling and polishing process. This not only affects the quality of the finished rice but also reduces the stability of equipment operation and increases equipment maintenance costs. Utility Model Content

[0036] Reference Figure 4 and Figure 5The internal sliding connection between the card block 4062 and the corresponding card slot 4064 allows for smooth sliding and engagement of the card block 4062 within the card slot 4064. The sizes of the card block 4062 and the card slot 4064 are matched to ensure that the card block 4062 can be accurately inserted into the card slot 4064 to form a firm connection. The rear adjacent sides of the two arc plates 405 are respectively attached to the left and right sides of the corresponding upright plate 401, allowing the arc plates 405 and the upright plate 401 to fit tightly together to form a stable structure. The front adjacent sides of the two arc plates 405 are attached to close and form a complete material storage and blocking space. The height of the upper disc 301 and the lower disc 302 is matched with that of the arc plate 405 to ensure that the arc plate 405 can effectively cover the rice milling and polishing area. The fixing block 4061 is attached to the adjacent side of the card block 4062 to ensure that the card block 4062 is installed firmly and can be accurately engaged in the card slot 4064.

[0037] Specifically, the card block 4062 slides within the corresponding slot 4064, and the two are sized to match, ensuring that the card block 4062 can be accurately inserted into the slot 4064 to form a strong snap-fit ​​structure, enhancing the stability of the fixing mechanism 406. The rear ends of the two arc-shaped plates 405 are attached to the upright plate 401, and the front ends are attached to each other, forming a closed material storage and blocking space, effectively preventing material leakage or splashing during processing. The height between the upper disc 301 and the lower disc 302 matches the arc-shaped plate 405, so that the arc-shaped plate 405 can effectively cover the rice milling and polishing areas after installation.

[0038] Working Principle: When using this vertical rice milling and polishing integrated machine, the material enters through the feed pipe 311 connected to the top left side of the top plate 2. The motor 3091, as the core of the power component 309, is fixed to the rear side of the worktable 1. After starting, the output end of the motor 3091 drives the active bevel gear 3092 to rotate. The active bevel gear 3092 meshes with the driven bevel gear 3093 at the bottom of the rotating rod 306, thereby causing the rotating rod 306 to rotate. The top of the rotating rod 306 passes through the polishing barrel 305 and the bottom of the rice milling barrel 303 in sequence, driving the rice milling sand roller 307 and polishing roller 308 fixed on the upper and lower sides of its outer wall to rotate synchronously. The material first enters the rice milling barrel 303. Under the high-speed rotation of the rice milling sand roller 307, the outer shell of the rice is... The rice grains are crushed and then pass through the connecting bucket 304 into the polishing bucket 305. Under the action of the polishing roller 308, the surface of the rice grains is further polished to improve the smoothness of the rice grains. During the rice milling and polishing process, the fan 3102 fixed inside the motor 3091 starts to work. The airflow generated by the fan 3102 flows through the mounting groove 3101 opened at the top of the top plate 2 to the polishing bucket 305 and the rice milling bucket 303 below. The airflow flows in the bucket, carrying away the rice bran and impurities generated during the rice milling and polishing process. The impurities are discharged with the airflow through the air outlets 3103 opened on the left and right sides of the lower disc 302. Multiple rotating plates 3104 connected to the air outlets 3103 can adjust the airflow direction and flow rate to ensure that the impurities are discharged smoothly.

[0039] Furthermore, the rotating shaft 402, which is fixed at the left and right ends of the adjacent side of the upper disc 301 and the lower disc 302, serves as the fulcrum for the rotation of the rotating rod 403, allowing multiple rotating rods 403 to rotate around the rotating shaft 402. One end of the rotating rod 403 is rotatably connected to the connecting block 404, and the other end is connected to the rotating shaft 402. By rotating the rotating rod 403, the connecting block 404 and the arc plate 405 connected to it are driven to rotate around the rotating shaft 402, adjusting the arc plate 405 to a suitable position to form a storage space. The fixing mechanism 406 on the front side of the arc plate 405 is used to lock the position of the arc plate 405. The fixing block 4061 fixed on the front side of the right arc plate 405 is provided with a locking block 4062, and the fixing block 4063 on the front side of the left arc plate 405 is provided with a slot 4064. By inserting the locking block 4062 into the slot 4064, the two arc plates 405 can be stably spliced ​​together, ensuring that the stored materials will not spill or leak.
