Description

Technical Field

[0001] This utility model relates to the field of rice processing technology, specifically a polishing machine for rice processing. Background Technology

[0002] Polishing refers to the treatment of the surface of rice grains to make them crystal clear and transparent, and to form a very thin gel film on the surface of the rice grains. The main function of rice polishing machines is to remove the bran powder adhering to the surface of white rice. After polishing, the rice surface has a waxy protective layer, which not only prevents the rice bran from adhering or the rice powder from falling off during the production, storage, transportation and sales stages, ensuring the cleanliness and hygiene of the rice, but also improves the quality and commercial value of the finished rice, facilitates the storage of rice, maintains the freshness of rice, and improves the eating quality of rice.

[0003] According to patent authorization number CN 218048045 U, a polishing machine for rice processing is disclosed. However, this application is not convenient for filtering rice bran, which affects the purity of the rice. Utility Model Content

[0023] 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.

[0024] Example

[0025] like Figure 1-5 As shown in the figure, an embodiment of the present invention discloses a polishing machine for rice processing, including a processing box 1. Support legs 5 are installed at both ends of the processing box 1. A feed hopper 2 is provided at the upper end of the processing box 1, and an adjusting component 3 is provided inside the feed hopper 2. A bearing plate 4 is installed at one end of the processing box 1. Two grinding rollers 7 are rotatably connected inside the processing box 1. Two polishing motors 6 are installed at one end of the processing box 1, and the output shafts of the two polishing motors 6 are respectively connected to the two grinding rollers 7. Two sliding grooves 10 are formed at the upper end of the bearing plate 4, and sliders 11 are slidably connected in each of the two sliding grooves 10. The upper end of each slider 11 is equipped with a material box 12. One end of the processing box 1 is equipped with a limiting component 9, and the processing box 1 is equipped with a screening screen 8. The polishing motor 6 drives the grinding roller 7 to rotate and perform polishing work. The screening screen 8 can collect rice bran and debris from the rice, improving the purity of the rice. The limiting component 9 facilitates the disassembly and cleaning of rice bran and debris, improving practicality. By adjusting the setting of the adjusting component 3, the amount of rice fed can be adjusted to avoid the phenomenon of insufficient polishing of rice due to excessive feeding at one time, thus improving the polishing effect.

[0026] The limiting assembly 9 includes a fixing block 91 installed at one end of the processing box 1. Two limiting rods 92 are installed inside the fixing block 91. A sliding plate 93 is slidably connected between the two limiting rods 92. A through plate 94 is installed at the bottom of the sliding plate 93 and is slidably connected to the fixing block 91. A stop plate 95 is installed at one end of the through plate 94. Two springs 96 are installed at the upper end of the sliding plate 93, and both springs 96 are connected to the fixing block 91. An extension plate 97 is installed at the upper end of the sliding plate 93. A handle 98 is installed at the upper end of the extension plate 97, and the extension plate 97 is slidably connected to the fixed block 91. By pulling the handle 98, the extension plate 97 is driven to slide up on the fixed block 91, and the slide plate 93 is driven to slide up on the limit rod 92, which compresses the spring 96. This causes the larger through plate 94 and the abutment plate 95 to move up, so that the abutment plate 95 no longer abuts against the material box 12. Then the material box 12 can be slid out of the slide groove 10 through the slider 11, which makes it easy to pour out the impurities in the material box 12 and make it easy to clean.

[0027] like Figure 1 As shown, in some embodiments, the abutment 95 abuts against the material box 12; this facilitates limiting the material box 12 and ensures the stability of impurity collection.

[0028] like Figure 3 As shown, in some embodiments, the adjusting component 3 includes a connecting seat 31 installed at one end of the feed hopper 2. A connecting rod 32 is rotatably connected inside the connecting seat 31. Two active bevel gears 34 are installed on the outer surface of the connecting rod 32. A servo motor 33 is installed at one end of the connecting seat 31. The output shaft of the servo motor 33 is connected to the connecting rod 32. Two rotating shafts are rotatably connected inside the feed hopper 2. Baffles 35 are installed on the outer surface of each of the two rotating shafts. A driven bevel gear 36 is installed at one end of each of the two rotating shafts. The servo motor 33 drives the connecting rod 32 to rotate, which in turn drives the active bevel gear 34 to rotate, which in turn drives the driven bevel gear 36 to rotate, which in turn drives the rotating shafts and baffles 35 to rotate. This adjusts the feeding range of the feed hopper 2, making it easier to adjust the amount of rice fed so that the rice is fully polished.

[0029] like Figure 3 As shown, in some embodiments, the driving bevel gear 34 and the driven bevel gear 36 mesh with each other; this facilitates adjustment.

[0030] like Figure 1 As shown, in some embodiments, the processing box 1 is provided with an observation window, and the material box 12 has a transparent structure; this facilitates observation.

[0031] 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 utility model. Although the 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 this utility model should be included within the protection scope of this utility model.
