Description

Technical Field

[0001] This utility model relates to the field of white rice grading technology, and in particular to a high-volume white rice grading sieve. Background Technology

[0002] Technological innovations in the field of automation control have made it possible to upgrade rice grading screens. The emergence of new materials, such as high-strength, corrosion-resistant screen materials with self-cleaning functions, can withstand greater material flow and extend the service life of the equipment. Advanced automation control technology can adjust grading parameters in real time according to rice flow and variety, ensuring that accurate grading can still be maintained under high output.

[0003] Furthermore, rice grading screens lack flexibility when processing different varieties of rice. The rice produced from japonica and indica rice differs significantly in grain shape, size, and density. Switching from processing round-grain Northeast rice to long-grain white rice often requires the equipment to be shut down for several hours for screen replacement and adjustment, greatly reducing production efficiency. However, the current output of rice grading screens on the market is less than 20 tons per hour. Such rice screens cannot meet the needs of a rice production line with a daily output of 500 tons, and their effect on precise grading of white rice is poor, failing to meet the grading requirements and thus reducing the grading effect. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a high-capacity white rice grading sieve, aiming to improve the existing technology. Currently, the output of white rice grading sieves on the market is less than 20 tons per hour. This type of white rice sieve cannot meet the needs of a rice production line with a daily output of 500 tons. At the same time, the effect of accurate grading of white rice is poor, which cannot meet the grading effect and thus reduces the grading effect.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a high-yield white rice grading sieve, comprising a sieve body, wherein the top left side of the sieve body is connected to a first layer of material distribution, the bottom of the first layer of material distribution is connected to a second layer of material distribution, the bottom of the second layer of material distribution is connected to a third layer of material distribution, the bottom of the third layer of material distribution is connected to a fourth layer of material distribution, the bottom left end of the sieve body is fixedly connected to a fifth layer of material distribution, the bottom of the fifth layer of material distribution is connected to a sixth layer of material distribution, the top right side of the sieve body is connected to a special rice outlet, the bottom of the special rice outlet is connected to a normal rice outlet, and the bottom of the normal rice outlet is connected to a broken rice outlet.

[0018] This utility model has the following beneficial effects:

[0019] 1. In this utility model, by lengthening the impurity removal layer flow plate, rice is guided to the outside of the screen body.

[0026] 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.

[0027] Please see the appendix Figure 1 - Appendix Figure 3 This utility model provides an embodiment of a high-yield white rice grading sieve, comprising a sieve body 1, a first layer of feed 8 connected to the top left side of the sieve body 1, a second layer of feed 9 connected to the bottom of the first layer of feed 8, allowing the grain to flow smoothly into the second layer of feed 9, which receives the grain from the first layer of feed 8, a third layer of feed 10 connected to the bottom of the second layer of feed 9, a fourth layer of feed 11 connected to the bottom of the third layer of feed 10, the fourth layer of feed 11 being the entire feed sieve, performing the final fine screening of the grain, a fifth layer of feed 13 fixedly connected to the bottom left side of the sieve body 1 after screening by the fourth layer of feed 11, a sixth layer of feed 14 connected to the bottom of the fifth layer of feed 13, a special rice outlet 4 connected to the top right side of the sieve body 1, a normal rice outlet 5 connected to the bottom of the special rice outlet 4, a broken rice outlet 6 connected to the bottom of the normal rice outlet 5, and a feed inlet 3 connected to the top right side of the sieve body 1.

[0028] Specifically, the first layer of material distribution 8 is located at the starting position of the entire material distribution process. When the grain enters the screen body 1 from above, it will first fall into the first layer of material distribution 8. Through the channel connected at the bottom of the first layer of material distribution 8, it will be further finely screened, and specific grains can be separated. The channel enters the third layer of material distribution 10. The fifth layer of material distribution 13 is for the previous layers of screening. The bottom of the fifth layer of material distribution 13 is connected to the sixth layer of material distribution 14. The sixth layer of material distribution 14 performs the final screening of the grain processed by the fifth layer of material distribution 13. The special rice outlet 4 is specifically for high-quality grains that have undergone strict screening through the previous multiple layers of material distribution. The bottom of the normal rice outlet 5 is connected to the broken rice outlet 6, which is mainly responsible for collecting the broken rice generated during the screening process.

[0029] Please see the appendix Figure 2 - Appendix Figure 4The bottom left end of the screen body 1 is rotatably connected to the lower distribution gate 12 near the edge, and the top left end of the screen body 1 is rotatably connected to the hinge 15 near the edge. The outer wall of the hinge 15 is rotatably connected to the upper distribution gate 7, so that the upper distribution gate 7 can rotate freely around it. The upper distribution gate 7 plays a screening control role. The front and rear ends of the outer wall of the upper distribution gate 7 are fixedly connected to the elongated plate 16. The right side of the granule discharge port 4 is rotatably connected to the circular cover 17. The inner side of the screen body 1 is fixedly connected to the wire mesh 2 at equal intervals. The equidistant distribution design makes the wire mesh 2 form a uniform screening plane inside the screen body 1. When the grain vibrates and flows inside the screen body 1.

[0030] Specifically, a hinge 15 is rotatably connected at the top left end of the screen body 1 near the edge. The hinge 15 serves as a connection to the upper distribution gate 7. By opening and closing the upper distribution gate 7, the flow rate and speed of grain entering the screen body 1 can be adjusted. The elongated plate 16 not only enhances the structural strength of the upper distribution gate 7, but also, when the upper distribution gate 7 is opened, the inner side of the screen body 1 is equidistantly connected with wire mesh 2. The wire mesh 2 is the core screening device. Grain particles smaller than the aperture of the wire mesh 2 will pass through the wire mesh 2 and fall down, while particles larger than the aperture will remain on the wire mesh 2, thereby achieving the grading and screening of grains of different particle sizes.

[0031] Working Principle: This design eliminates the two-layer parallel device of the double-layer rice sieve in a single screening operation, replacing it with a four-layer parallel device. The impurity removal layer's flow plate is lengthened to guide the rice outside the sieve body 1. An upper distribution gate 7 and a lower distribution gate 12 are designed on the outside of the sieve body 1. Both the upper and lower distribution gates 7 and 12 have multiple dividing channels of the same width but different heights. Each sieve surface corresponds to four channels, evenly distributing the material to the four sieve surfaces: the first layer (distributing material 8), the second layer (distributing material 9), the third layer (distributing material 10), and the fourth layer (distributing material 11). The material from the four layers of distribution in the single screening operation collects in the front-end internal discharge hopper. The material is then discharged from the sieve body 1 through a circular pipe outlet at the bottom of the discharge hopper. Each of the upper three layers' flow plates has a special rice discharge port 4, a normal rice discharge port 5, and a broken rice discharge port 6 at its front end. The undersize material flows through the flow plate... The material flows to the special rice outlet 4, the normal rice outlet 5, and the broken rice outlet 6, then flows to the outer sides of the screen body 1 and collects. It then enters the fourth layer reverse flow plate and is collected with the undersize material of the fourth layer. The material flows through the fourth layer flow plate into the parallel feeding gates of the fifth layer distribution 13 and the sixth layer distribution 14. The material is evenly distributed to the fifth layer distribution 13 and the sixth layer distribution 14 for screening. The undersize material of the fifth layer distribution 13 flows through the special rice outlet 4, the normal rice outlet 5, and the broken rice outlet 6 into the outside of the box body. It falls through the guide pipe to the height plate of the undersize material of the sixth layer distribution 14, and then enters the internal collection hopper of the sixth layer distribution 14 forward flow plate for collection. It is discharged from the screen body 1 through the round pipe at the bottom of the collection hopper, thus achieving high-capacity screening and meeting daily use needs.

[0032] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
