Description

Technical Field

[0001] This utility model relates to the technical field of rice processing equipment, and in particular to a rice milling machine for rice processing. Background Technology

[0002] In the rice processing industry, the rice milling machine is a core piece of equipment, and its performance directly affects the processing quality and production efficiency of rice. Traditional rice milling machines have revealed many problems that urgently need to be addressed in practical use.

[0003] Firstly, in terms of adaptability, most traditional rice milling machines have a fixed spacing between their milling rollers, making it difficult to flexibly meet the processing needs of rice with different grain sizes. When faced with paddy rice of varying sizes, the fixed-spacing milling rollers either fail to adequately remove the bran layer, resulting in incomplete milling, or they over-extract the rice, causing a significant increase in broken rice, which seriously affects the quality and yield of the rice and reduces the economic benefits for the enterprise.

[0004] Secondly, there are significant deficiencies in the cleaning and maintenance process. During rice milling, broken rice and bran easily adhere to the surface of the milling rollers. These impurities not only hinder the normal rotation of the milling rollers and increase energy consumption, but also affect the uniformity and quality of the milled rice. Traditional rice milling machines lack effective cleaning devices, requiring frequent machine shutdowns for manual cleaning, which is not only labor-intensive but also leads to production interruptions, greatly reducing production efficiency.

[0005] Furthermore, the feeding process lacks a reasonable guidance mechanism. After the rice to be processed enters the rice milling machine, it is easy for it to be unevenly distributed. Some rice cannot enter the rice milling rollers smoothly, resulting in low rice milling efficiency and even equipment blockage, affecting the continuity of production.

[0006] In summary, existing rice milling machines for rice processing have shortcomings in terms of adaptability, cleaning and maintenance, and feeding guidance. Developing a new type of rice milling machine that can flexibly adjust the spacing between the milling rollers, has efficient cleaning functions, and optimizes the feeding process is of significant practical importance for improving the production level and reducing production costs in the rice processing industry.

[0007] The information disclosed in this background section is intended only to enhance the understanding of the overall background of this utility model and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art.

[0047] Specifically, in order to guide the rice to be processed into the rice milling machine housing 1 through the feed hopper 11 to the position between the two rice milling rollers 2, two guide plates are fixed on the inner walls of the front and rear sides of the rice milling machine housing 1.

[0048] Specifically, in order to prevent rice and rice bran from entering the guide port, the slider 22 is T-shaped.

[0049] Specifically, in order to ensure that the mounting plate 24 can slide stably along the direction of the guide groove, a guide block 241 is fixedly installed on the side of the mounting plate 24 near the rice milling machine housing 1. Guide grooves are provided on both the front and rear sides of the rice milling machine housing 1, and the two guide blocks 241 are slidably installed in the corresponding guide grooves.

[0050] The circuits, electronic components, and module mechanisms involved all employ existing technologies, which can be fully implemented by those skilled in the art, and need no further explanation. The content protected by this application does not involve any improvement to the software, circuits, or methods.

[0051] Working principle:

[0052] Feeding and diversion

[0053] The rice to be processed enters the rice milling machine housing 1 from the feed hopper 11. Since there are two guide plates fixed on the inner walls of the front and rear sides of the rice milling machine housing 1, which are symmetrically arranged based on the feed hopper 11 and located above the two rice milling rollers 2, the rice will be guided by the guide plates to the position between the two rice milling rollers 2, preparing for the subsequent rice milling operation.

[0054] Rice milling operation

[0055] When the power is turned on and the drive motor 3 is started, its output shaft drives the drive gear 31 to rotate. The drive gear 31 meshes with one of the two linkage gears 26 on the front side, thereby driving the linkage gear 26 to rotate. Since the two linkage gears 26 located on the same side of the rice milling machine housing 1 mesh with each other, the two linkage gears 26 will rotate synchronously in opposite directions.

[0056] Since each linkage gear 26 is fixedly mounted on a different rotating pin 25, and sprockets 27 are fixedly mounted on both the rotating pin 25 and the rotating shaft 21, and the eight sprockets 27 are connected by four chains 28, the rotation of the linkage gear 26 is transmitted to the rotating shaft 21 through the sprockets 27 and the chains 28, so that the two rotating shafts 21 always keep rotating synchronously in opposite directions. The two rice milling rollers 2 fixedly mounted on the rotating shaft 21 will also rotate synchronously in opposite directions to mill the rice located between them, remove the outer shell and part of the bran of the rice, and realize the rice milling process.

[0057] Rice milling roller spacing adjustment

[0058] When it is necessary to adjust the distance between the two rice milling rollers 2, the adjustment motor 44 is started. The output shaft of the adjustment motor 44 drives the driven gear 43 fixedly sleeved on the screw sleeve 42 to rotate through the driving gear 45, thereby controlling the rotation of the screw sleeve 42. Since the fixing screw 41 is threaded in the screw sleeve 42 and the top end of the fixing screw 41 is fixedly connected to the front mounting plate 24, the rotation of the screw sleeve 42 will cause the fixing screw 41 to move up and down, thereby driving the front mounting plate 24 to move up and down.

[0059] When the mounting plate 24 moves, it controls the sliders 22 on both sides to move closer to each other or further away from each other through the strip plate 23 and the rotating shaft 21, thereby realizing the adjustment of the gap between the rice milling rollers 2. At the same time, due to the transmission method of the sprocket 27 and the chain 28, even if the gap between the two rotating shafts 21 changes, they can still maintain synchronous reverse rotation.

[0060] Cleaning operation

[0061] During the operation of the rice milling machine, two cleaning scrapers 5, which are rotatably mounted on the inner walls of the front and rear sides of the rice milling machine housing 1, respectively contact the corresponding rice milling rollers 2. The cleaning scrapers 5 scrape off the broken rice and rice bran and other impurities adhering to the rice milling rollers 2. When the distance between the two rice milling rollers 2 is adjusted, the cleaning scrapers 5 are adaptively adjusted by the torsion springs 52 fixedly installed on their front and rear sides. One end of the torsion spring 52 is fixedly connected to the cleaning scraper 5, and the other end is fixedly connected to the inner wall of the rice milling machine housing 1. The torsion spring 52 is slidably sleeved on the outside of the corresponding rotating rod 51. In this way, the torsion spring 52 can adapt to the change in the position of the rice milling rollers 2 while ensuring that the cleaning scraper 5 is in contact with the rice milling rollers 2.

[0062] Meanwhile, support blocks 61 are slidably installed in the inclined grooves on the inner walls of the front and rear sides of the rice milling machine housing 1. The same cleaning brush 6 is fixedly installed between the two support blocks 61 on the same side. The cleaning brush 6 is in contact with the corresponding rice milling roller 2. The support block 61 is slidably connected to the guide rod 62 fixed in the groove. When the position of the rice milling roller 2 changes, the support block 61 will slide on the guide rod 62, so that the cleaning brush 6 can achieve adaptive adjustment and continue to clean the debris adhering to the rice milling roller 2.

[0063] In addition, the purpose of the T-shaped slider 22 is to prevent rice and rice bran from entering the guide opening and to ensure that the slider 22 slides normally in the guide opening. The design of the guide block 241 and the guide groove ensures that the mounting plate 24 can slide stably along the direction of the guide groove, thereby making the adjustment of the spacing of the rice milling roller 2 more stable and reliable.

[0064] The rice milling machine for rice processing provided by this utility model has been described in detail above. Specific embodiments have been used to illustrate the principle and implementation of this utility model. The description of the embodiments above is only for the purpose of helping to understand the method and core idea of ​​this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made to this utility model without departing from the principle of this utility model, and these improvements and modifications also fall within the protection scope of the claims of this utility model.
