Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of rice processing, and in particular to a rice desiccant device. Background Technology
[0002] During rice processing, it is necessary to effectively remove any debris (such as broken rice grains and bran powder) to ensure the quality and purity of the finished rice.
[0003] Currently, when removing rice husks, sieves are commonly used to separate the rice particles. To facilitate rice discharge, sieves are typically designed at an angle. While this design promotes material flow, the rice, due to gravity, slides down more quickly, shortening its residence time on the sieve surface. Since sieving requires sufficient time for particles to fully contact the sieve openings, insufficient residence time prevents fine particles from passing through, resulting in incomplete sieving and affecting the sieving effect. Utility Model Content

[0019] The embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention. Rather, the embodiments of the present invention include all variations, modifications, and equivalents falling within the spirit and scope of the appended claims.
[0020] The rice husk removal device of this utility model embodiment will be described below with reference to the accompanying drawings.
[0021] like Figures 1-3 As shown, the rice husk removal device of this utility model embodiment includes a base 10, a processing box 30, a vibrating screening mechanism 40, a rotating feeding mechanism 50, and a collecting mechanism 60. Two upright plates 21 are arranged opposite each other on one side of the top surface of the base 10. The two upright plates 21 are rotatably connected to rotating shafts 22, and a mounting plate 23 is connected between the two rotating shafts 22. The processing box 30 is connected to the mounting plate 23. A hydraulic rod 24 is hinged between the base 10 and the processing box 30. The vibrating screening mechanism 40 is disposed inside the processing box 30. A support 31 is provided on the top surface of the processing box 30, and a feeding hopper 32 is connected to the support 31. The rotating feeding mechanism 50 is connected to the feeding hopper 32 and penetrates the top wall of the processing box 30. The collecting mechanism 60 is disposed on one side of the processing box 30 and communicates with the processing box 30. The collecting mechanism 60 is located on one side of the vibrating screening mechanism 40.
[0022] It should be noted that a door is hinged on one side of the processing box 30, and an observation window is provided on the door to facilitate staff to observe the de-dust removal process of the rice inside the processing box 30.
[0023] Specifically, in the rice production workshop, the staff first activates the rotary feeding mechanism 50 and the vibrating screening mechanism 40, and then puts the rice to be de-dusted into the feed hopper 32. Under the action of the rotary feeding mechanism 50, the rice can fall more evenly onto the vibrating screening mechanism 40. Then, the vibrating screening mechanism 40 screens the broken rice grains and bran powder in the rice. The size of the broken rice grains and bran powder is smaller than that of the rice grains. During the screening process, the broken rice grains and bran powder pass through the vibrating screening mechanism 40 and fall down, while the rice stays above the vibrating screening mechanism 40.
[0024] After screening, the hydraulic rod 24 is activated, causing the piston end of the hydraulic rod 24 to retract. With the cooperation of the rotating shaft 22, the processing box 30 tilts downward, and the vibrating screening mechanism 40 also tilts. This causes the rice to roll downward under gravity and fall into the collection mechanism 60. During this process, the staff observes the situation inside the processing box 30. After all the rice has fallen into the collection mechanism 60, the hydraulic rod 24 is activated, causing the piston end of the hydraulic rod 24 to return to its original position, making the processing box 30 horizontal.
[0025] The rice husk removal device of this utility model can keep the vibrating screening mechanism in a horizontal state during the screening process, thereby effectively enhancing the screening effect. After screening, it is adjusted to an inclined state to facilitate the smooth discharge of materials.
[0026] In one embodiment of this utility model, such as Figure 1 and Figure 3 As shown, the vibrating screening mechanism 40 includes a mounting frame 41, a screening screen 42, multiple springs 43, two fixing plates 44, and a vibrator 45. The processing box 30 has a discharge port 33 on one side. The mounting frame 41 abuts against the inner wall of the processing box 30 and extends into the discharge port 33. The screening screen 42 is connected to the mounting frame 41. The two fixing plates 44 are respectively connected to the two side walls of the processing box 30. The multiple springs 43 are respectively disposed between the two fixing plates 44 and the mounting frame 41. The vibrator 45 is disposed on the bottom surface of the screening screen 42.
[0027] It should be noted that the vibrator 45 described in this embodiment can be a vibrating motor. The mesh size of the sieve 42 is smaller than the size of the rice. The vibrator 45 and the spring 43 work together to drive the sieve 42 and the mounting frame 41 to vibrate, thereby screening the debris in the rice. During the screening process, the debris passes through the sieve 42 and falls down, while the rice stays above the sieve 42 and can be discharged through the discharge port 33.
[0028] In one embodiment of this utility model, such as Figure 1As shown, the rotary feeding mechanism 50 includes a feeding pipe 51, a rotary joint 52, a driver 53, a first gear 54, and a second gear 55. The feeding pipe 51 passes through the top wall of the processing box 30, and the bottom end of the feeding pipe 51 is inclined. The rotary joint 52 is located between the bottom end of the feed hopper 32 and the feeding pipe 51. The driver 53 is located on the top surface of the processing box 30. The first gear 54 is located at the output end of the driver 53. The second gear 55 meshes with the first gear 54 and is located on the feeding pipe 51.
[0029] It should be noted that the driver 53 described in this embodiment can be a servo motor. The feeding pipe 51 is rotatably connected to the top wall of the processing box 30. The driver 53 can drive the first gear 54, the second gear 55 and the feeding pipe 51 to rotate. During use, the operator puts the rice to be de-dusted into the feeding hopper 32, and then the rice enters the feeding pipe 51. During the rotation of the feeding pipe 51, the rice will fall more evenly onto the vibrating screening mechanism 40. By setting the rotary joint 52, the feeding hopper 32 can be kept stationary during the rotation of the feeding pipe 51, which makes it convenient for the operator to put rice into the feeding hopper 32.
[0030] In one embodiment of this utility model, such as Figure 1 As shown, the collection mechanism 60 includes a collection box 61 and a drawer 62. The collection box 61 is located on one side of the processing box 30 and is connected to the discharge port 33. The drawer 62 is slidably disposed inside the collection box 61.
[0031] It should be noted that the collection box 61 has an opening on one side corresponding to the discharge port 33. Rice will enter the collection box 61 from the discharge port 33 and the opening, and then fall into the drawer 62. The staff can collect the rice by pulling out the drawer 62.
[0032] In one embodiment of this utility model, such as Figure 1 As shown, the inner bottom wall of the processing box 30 is provided with a collection trough 70.
[0033] Understandably, by setting up the collection trough 70, the debris separated from the rice can be collected. The staff can open the door of the processing box 30, take out the collection trough 70, and clean up the debris.
[0034] In summary, the rice husk removal device of this utility model can keep the vibrating screening mechanism in a horizontal state during the screening process, thereby effectively enhancing the screening effect. After screening, it can be adjusted to an inclined state to facilitate the smooth discharge of materials.
