Description

Technical Field

[0001] The utility model relates to the technical field of rice processing equipment, in particular to a impurity removal and screening mechanism for rice processing. Background Technique

[0002] In the rice processing industry, impurity removal and screening are key links to ensure rice quality and production efficiency. In the traditional rice processing process, these steps often rely on manual operation or simple mechanical devices to complete. However, these methods have many inherent limitations and problems.

[0003] First of all, relying on manual labor for impurity removal and screening is not only inefficient, but also easily affected by human factors, resulting in inconsistent processing results. In addition, long-term manual labor will also increase the fatigue of workers, thereby affecting work quality and efficiency.

[0004] Secondly, although traditional mechanical devices can improve the processing efficiency to a certain extent, they often perform poorly in terms of the accuracy of impurity removal and screening. Especially for light impurities such as dust and rice bran, traditional equipment is often difficult to effectively remove, thus affecting the purity and quality of the final product.

[0005] Furthermore, traditional rice processing equipment has obvious deficiencies in terms of continuity and automation. The connection between equipment is not smooth enough, and manual intervention is often required for material transfer and equipment adjustment. This not only reduces the overall production efficiency, but also increases production costs and the possibility of errors. In view of this, we propose an impurity removal and screening mechanism for rice processing. Content of the Utility Model

[0024] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0025] Please refer to Figures 1 - 4 , the present invention provides a technical solution:

[0026] The impurity removal and screening mechanism for rice processing includes a feeding hopper 1. A support plate 7 is fixedly connected to the bottom of the feeding hopper 1. An air extraction assembly 4 is installed on the support plate 7, and the air inlet of the air extraction assembly 4 is located below the discharge port of the feeding hopper 1; it also includes a support frame 2 fixedly connected to the outer wall of the air extraction assembly 4. An inclined sieve mesh 3 is fixedly installed inside the support frame 2. One end of the sieve mesh 3 close to the discharge port of the feeding hopper 1 is higher, and the height is lower than the air inlet of the air extraction assembly 4; it also includes a belt conveyor 8. One end of the belt conveyor 8 extends below the lower end of the sieve mesh 3, and the other end extends out from the perforation 20 of the support frame 2. By setting structures such as the feeding hopper 1, the support plate 7, the air extraction assembly 4, the support frame 2, and the sieve mesh 3, the functions of automatic impurity removal and screening of rice are realized. The feeding hopper 1 is used to put in rice, the sieve mesh 3 is responsible for screening, and the air extraction assembly 4 can suck away light impurities, thereby improving the purity of rice. At the same time, the belt conveyor 8 can transport the screened rice to the next process, realizing automated and continuous rice processing and improving production efficiency.

[0027] As a preference of this embodiment, two baffles 11 are symmetrically and rotatably installed near the bottom inside the feeding hopper 1, and a rotating shaft 12 fixedly connected to the inner wall of the feeding hopper 1 is fixed near the top of the two baffles 11. By installing two baffles 11 inside the feeding hopper 1, the feeding speed of rice can be controlled.

[0028] Preferably, in this embodiment, two flipping motors 10 are fixedly installed on the outer wall of the feeding hopper 1, and the output shafts of the two flipping motors 10 are coaxially fixed to the two rotating shafts 12 respectively. By installing the flipping motors 10 and the rotating shafts 12, the flipping of the partition plate 11 can be controlled, thereby further adjusting the feeding speed and direction of the rice. This dynamic adjustment function can adapt to different processing requirements and improve the flexibility and applicability of the equipment.

[0029] Preferably, in this embodiment, the air extraction assembly 4 includes a mounting frame 40 fixedly connected to both the support frame 2 and the support plate 7. An air collection hood 41 is integrally formed on the outside of the mounting frame 40, and a mesh collection bag 5 is detachably installed on the connecting pipe 42 of the air collection hood 41. The designs of the air collection hood 41 and the connecting pipe 42 can effectively collect and process the impurities sucked away by the air extraction assembly 4, and the mesh collection bag 5 facilitates cleaning and replacement. This design not only improves the impurity removal efficiency but also reduces the maintenance cost.

[0030] Preferably, in this embodiment, a mounting plate 43 is fixedly installed inside the mounting frame 40. Two mounting holes 45 are symmetrically formed on the mounting plate 43, and a fan blade assembly is installed in each mounting hole 45. The light and small impurities in the rice can be sucked out through the fan blade assemblies in each mounting hole 45.

[0031] Preferably, in this embodiment, the fan blade assembly includes a vertical plate 46 fixedly connected to the inner wall of the mounting hole 45. A fan motor 48 is installed on the vertical plate 46, and a fan blade 47 is coaxially fixed to the output shaft of the fan motor 48. When in use, the fan blade 47 is driven to rotate by the fan motor 48.

[0032] Preferably, in this embodiment, a shielding net 44 is fixedly connected to the outer wall of the mounting frame 40 on the side away from the air collection hood 41. The provided shielding net 44 can prevent the rice from being sucked out together with the light and small impurities.

[0033] Preferably, in this embodiment, a base 70 is fixedly connected to the bottom of the support plate 7. The base 70 is fixedly connected to the bottom of the support plate 7, enhancing the stability of the entire impurity removal and screening mechanism. The base 70 can provide a larger support area and a more stable support force.

[0034] When the impurity removal and screening mechanism for rice processing of the present utility model is in use, first, the rice to be processed is put in through the feeding hopper 1. Inside the feeding hopper 1, the two symmetrically installed partition plates 11 play a role in controlling the feeding speed and direction of the rice. These partition plates 11 are rotatably connected to the inner wall of the feeding hopper 1 through the rotating shafts 12 and can be dynamically adjusted through the flipping motors 10 to adapt to different processing requirements.

[0035] When the rice flows out of the discharge port of the feeding hopper 1, it will fall onto the inclined screen 3. The screen 3 is responsible for screening the rice and removing the larger impurities or defective particles therein. At the same time, since the screen 3 is inclined, the rice will slide downward under the action of gravity.

[0036] Above the screen 3, an air extraction assembly 4 is installed. The air extraction assembly 4 includes parts such as a mounting frame 40, a gas collection hood 41, and a connecting pipe 42. When the rice falls onto the screen 3, the air extraction assembly 4 will suck away the light impurities in the rice, such as dust and broken rice husks, through its air inlet. After being sucked in, these impurities will enter the mesh collection bag 5 through the connecting pipe 42, which is convenient for subsequent cleaning and replacement.

[0037] The rice that has been screened and decontaminated will slide down from the lower end of the screen 3 and fall onto the belt conveyor 8. The belt conveyor 8 will transport this rice to the next process for further processing. In this way, the impurity screening mechanism for rice processing of the present utility model realizes automated and continuous rice processing, improving the production efficiency and the purity of the rice.

[0038] It should be added that a collection trough 6 is provided below the screen 3.

[0039] The above shows and describes the basic principles, main features, and advantages of the present utility model. Those skilled in the art should understand that the present utility model is not limited by the above embodiments. The above embodiments and the descriptions in the specification are only preferred examples of the present utility model and do not limit the present utility model. Without departing from the spirit and scope of the present utility model, the present utility model will have various changes and improvements, and these changes and improvements all fall within the scope of the present utility model claimed. The scope of protection claimed by the present utility model is defined by the appended claims and their equivalents.
