Description

Technical Field

[0001] This utility model belongs to the field of rice processing technology, specifically relating to an anti-breakage device for rice processing. Background Technology

[0002] Tubular chain conveyors are a type of continuous conveying equipment widely used in various industries. They are primarily used for conveying loose rice in powdery, granular, and lump form. This powerful, adaptable, and environmentally friendly continuous conveying system is widely applied in rice processing plants for raw material transport, rice transfer on production lines, and finished product packaging. It can be used in conjunction with other equipment such as screening machines, dryers, and packaging machines to form a complete production line, improving production efficiency and product quality.

[0003] During the rice conveying process, the tubular chain conveyor uses chain links as the transmission component. The movement of the chain links drives the rice to move along the pipe. When conveying horizontally, the rice is pushed by the chain links in the direction of movement. When the internal friction between the rice grains is greater than the external friction between the rice grains and the pipe wall, the rice moves forward with the chain links, forming a stable conveying. When conveying vertically, the rice in the pipe is pushed upward by the chain links. Because the continuous conveying of rice at the bottom prevents the rice at the top from sliding down, lateral pressure is generated, which enhances the internal friction of the rice. When the internal friction between the rice grains is greater than the external friction between the rice grains and the inner wall of the pipe and the weight of the rice itself, the rice is conveyed upward with the chain links, forming a continuous flow of material.

[0004] However, during the conveying process within the tubular chain conveyor, rice grains follow the conveying system into the gaps between contact points, where they are subjected to physical contact compression, crushing, and friction. These forces may exceed the rice grains' bearing capacity, causing them to break. Broken rice, due to its increased surface area, is more likely to absorb moisture and impurities from the air, thus increasing the risk of dampness and mold. Simultaneously, changes in grain shape and physical properties also deteriorate the rice's texture. For example, when cooking porridge or rice, broken rice may be more easily overcooked or become sticky, affecting the taste and reducing its nutritional value. Therefore, the nutritional value, physical properties, storage and processing performance, and eating quality of the rice are all affected. Utility Model Content

[0005] The purpose of this invention is to provide a rice processing anti-breakage device, which aims to solve the above-mentioned problems existing in the prior art.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A rice processing anti-breakage device includes a rice processing chamber, on which a plurality of tubular chain conveyors are mounted. Each tubular chain conveyor has a conveying pipe and a drive mechanism. The plurality of tubular chain conveyors are connected to each other through the conveying pipe. Each of the tubular chain conveyors has a corner driven wheel cavity at a turning point and a driven wheel is mounted in the corner driven wheel cavity. The driven wheel is arranged in a radial pattern with protruding ends evenly distributed along the center and circumference, and the end of the protruding end is provided with a driven wheel cylindrical top bar.

[0008] A chain is slidably installed inside the conveying pipe, and circular scrapers are fixedly installed on the chain at equal intervals.

[0009] In a preferred embodiment of this utility model, the distance between the protruding ends of the driven wheels is the same as the distance between the scrapers.

[0010] In a preferred embodiment of the present invention, the driven wheel cylindrical top bar is in columnar shape and makes point contact with the chain (9).

[0011] In a preferred embodiment of this utility model, the length of the driven wheel cylindrical top bar is greater than or equal to the width of the chain.

[0012] In a preferred embodiment of this utility model, the outer surface of the driven wheel cavity is further equipped with a shaft and a bearing with a seat, and the drive mechanism drives the driven wheel to rotate through the shaft and the bearing with a seat.

[0013] In a preferred embodiment of this utility model, the inner wall of the driven wheel cavity is fitted to the driven wheel and a rotation gap is reserved.

[0014] In a preferred embodiment of this utility model, the two ends of the tubular chain conveyor are respectively connected to a rice inlet and a rice outlet via pipes.

[0015] In a preferred embodiment of this utility model, the edge of the scraper is rounded and slides against the wall of the conveying pipe.

[0016] In summary, the beneficial effects of the above-described technical solutions conceived by this utility model compared with the prior art include:

[0017] This utility model relates to an anti-breakage device for rice processing. As the scraper slides along the chain within the conveying pipe, it synchronously conveys the rice between the two scrapers. Furthermore, the cylindrical design of the driven wheel's cylindrical top bar prevents it from inserting into the chain during movement, significantly reducing the contact area between them. This is particularly noticeable in the corner driven wheel cavity, reducing shearing and direct collisions with the rice grains and effectively minimizing the crushing effect of the chain and driven wheel on the rice, thus drastically reducing the breakage rate. Simultaneously, the close fit between the corner driven wheel cavity and the driven wheel reduces the grain storage space within the corner driven wheel cavity, preventing excessive rice accumulation and collision / friction. The circular scraper reduces friction between the rice and the inner wall of the conveying pipe during transport, further reducing the risk of breakage due to collisions, compression, and friction. This ensures the integrity of the rice grains and their physical properties, thereby improving the economic value, storage and processing performance, and edible quality of the rice.

[0023] To more clearly illustrate the technical solutions in the embodiments of this utility model or the prior art, the present utility model will be briefly introduced below in conjunction with the accompanying drawings and descriptions of the embodiments or the prior art. Obviously, the following description of the structure of the accompanying drawings is only some embodiments of this utility model.

It should be noted that the description of these embodiments is used to help understand this utility model, but does not constitute a limitation on this utility model.

[0024] Example:

[0025] like Figure 1-4 As shown, this embodiment provides a rice processing anti-breakage device, including a rice processing chamber 1, on which a plurality of tubular chain conveyors 2 are mounted. Each tubular chain conveyor 2 has a conveying pipe 3 and a drive mechanism 4. The plurality of tubular chain conveyors 2 are connected to each other through the conveying pipe 3. Each tubular chain conveyor 2 has a corner driven wheel cavity 5 at a turning point and a driven wheel 6 is mounted in the corner driven wheel cavity 5. The driven wheel 6 is arranged in a radial pattern with protruding ends evenly distributed along the center to the circumference, and the end of the protruding end is provided with a driven wheel cylindrical top bar 7.

[0026] A chain 9 is slidably installed inside the conveying pipe 3, and circular scrapers 10 are fixedly installed on the chain 9 at equal intervals.

[0027] In a specific application scenario, as the scraper 10 slides within the conveying pipe 3 along with the chain 9, it synchronously conveys the rice between the two scraper blades 10. Furthermore, due to the cylindrical design of the driven wheel's cylindrical top bar 7, it does not insert into the chain 9 during operation, significantly reducing the contact area between them. This is particularly noticeable in the corner driven wheel cavity 5, reducing shearing and direct collisions with the rice grains and effectively minimizing the crushing effect of the chain 9 and driven wheel 6 on the rice, thus drastically reducing the rice breakage rate. Simultaneously, the fit between the cavity of the corner driven wheel cavity 5 and the driven wheel 6 reduces the grain storage space within the corner driven wheel cavity 5, preventing excessive rice accumulation and collision / friction. The rounded corner grinding of the scraper blades 10 reduces friction between the rice and the inner wall of the conveying pipe 3 during transport, further reducing the risk of rice breakage due to collision, compression, and friction during transport. The following description, in conjunction with this application scenario, further elaborates on the anti-breakage device for rice processing of this utility model.

[0028] Furthermore, referring to Figure 1-4 The distance between the protruding ends of the driven wheel 6 is the same as the distance between the scrapers 10.

[0029] In this embodiment, in order to ensure the accuracy of the driven wheel 6 during the turning process, the distance between the ends of the driven wheel 6 is set to be consistent with the distance between the scrapers 10, thereby maintaining the linkage between the driven wheel 6 and the scrapers 10, achieving the driving function of the chain 9, and thus enabling the chain 9 to slide in the conveying pipe 3 to complete the rice conveying.

[0030] In more detail, refer to Figure 1-4 The driven wheel cylindrical top bar 7 is in columnar contact with the chain 9 at point 9.

[0031] In this embodiment, in order to reduce the risk of collision and friction between the driven wheel cylindrical top bar 7 and the rice grains during the turning process, the driven wheel cylindrical top bar 7 is set in a columnar shape and the surface is polished smooth. This avoids the situation where the rice is damaged during the rotation drive of the traditional sprocket and protects the integrity of the rice during transportation.

[0032] More preferably, refer to Figure 1-4 The length of the driven wheel cylindrical top bar 7 is greater than or equal to the width of the chain 9.

[0033] In this embodiment, since the pushing of the chain 9 requires the driven wheel cylindrical top bar 7 to contact the chain 9, the driven wheel cylindrical top bar 7 drives the chain 9 synchronously as the driven wheel 6 rotates. At this time, in order to avoid misalignment during the contact between the driven wheel cylindrical top bar 7 and the chain 9, the length of the driven wheel cylindrical top bar 7 is set to be greater than or equal to the width of the chain 9. Thus, no matter how the driven wheel cylindrical top bar 7 is misaligned, it can maintain contact with the chain 9, thereby ensuring the stable pushing of rice.

[0034] More preferably, refer to Figure 1-4 The outer surface of the driven wheel cavity 5 is also equipped with a shaft 8 and a bearing 11, and the drive mechanism 4 drives the driven wheel 6 to rotate through the shaft 8 and the bearing 11.

[0035] In this embodiment, in order to drive the driven wheel 6 to rotate, a shaft 8 and a bearing 11 are also installed on the outer facade. Thus, during the driving operation of the drive mechanism 4, the driven wheel 6 is driven to rotate through the shaft 8 and the bearing 11, thereby maintaining the rotational pushing function of the driven wheel 6 on the chain 9 and keeping the conveying of the chain 9 stable.

[0036] Furthermore, referring to Figure 1-4 The inner wall of the driven wheel cavity 5 is fitted with the driven wheel 6 and a rotation gap is reserved.

[0037] In this embodiment, in order to avoid excessive accumulation of rice grains in the corner driven wheel cavity 5 during the conveying process, the inner wall of the corner driven wheel cavity 5 is set to fit the driven wheel 6 and a rotation gap is reserved. While maintaining the stable rotation of the driven wheel 6, the grain storage space in the corner driven wheel cavity 5 is reduced, the amount of rice in the corner driven wheel cavity 5 is reduced, and thus the accumulation and friction of rice are avoided.

[0038] Furthermore, referring to Figure 1-4 The two ends of the tubular chain conveyor 2 are respectively connected by pipes to the rice inlet and the rice outlet.

[0039] In this embodiment, since the tubular chain conveyor 2 is used to transport rice in conjunction with the rice processing chamber 1 for different processing steps, the two ends of the tubular chain conveyor 2 are respectively connected to rice inlet and rice outlet, so that the rice can quickly start other processing steps after passing through the conveyor, thereby improving the processing efficiency of rice.

[0040] More specifically, refer to Figure 1-4 The scraper blade 10 has its edges rounded and slides against the wall of the conveying pipe 3.

[0041] In this embodiment, in order to reduce the friction between the rice and the wall of the conveying pipe 3 during the rice conveying process, the scraper 10 is set with rounded edges and is slidably connected to the wall of the conveying pipe 3 to maintain the sealing between the two scrapers 10 and avoid the risk of the rice sliding into the gap between the scraper 10 and the wall of the conveying pipe 3, thereby reducing the friction on the rice.

[0042] Working principle:

[0043] This utility model relates to an anti-breakage device for rice processing. After rice enters the conveying pipe 3 from the feed inlet at one end of the tubular chain conveyor 2, the drive mechanism 4 drives the shaft 8 to rotate, which in turn drives the driven wheel 6 to rotate synchronously. This causes the cylindrical top bar 7 of the driven wheel to rotate synchronously and insert its end into the space between the two scrapers 10 on the chain 9. As the cylindrical top bar 7 rotates with the driven wheel 6, it moves the scrapers 10, causing the chain 9 to slide within the conveying pipe 3. This pulls and pushes both ends of the chain 9, helping the chain 9 to slide smoothly within the conveying pipe 3.

[0044] At this time, as the scraper 10 slides within the conveying pipe 3 along with the chain 9, it drives the rice between the two scraper blades 10 to be conveyed synchronously. Moreover, due to the cylindrical design of the driven wheel cylindrical top bar 7, the driven wheel cylindrical top bar 7 will not insert into the chain 9 during the prying process, significantly reducing the contact area between the two. Especially in the corner driven wheel cavity 5, it reduces the shearing and direct collision of rice particles, effectively reducing the crushing effect of the chain 9 and driven wheel 6 on the rice, thereby greatly reducing the rice breakage rate. At the same time, the fit between the cavity of the corner driven wheel cavity 5 and the driven wheel 6 reduces the grain storage space in the corner driven wheel cavity 5, avoiding excessive rice accumulation in the corner driven wheel cavity 5 for collision and friction. Through the rounded corner grinding treatment of the scraper 10, the friction between the rice and the inner wall of the conveying pipe 3 during the conveying process is reduced, thereby further reducing the risk of rice breaking due to collision, squeezing, and friction during the conveying process.

[0045] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the scope of protection of this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the scope of protection of this utility model.
