Description

Technical Field

[0001] This utility model relates to the field of vertical rice milling machine technology, and in particular to a cleaning device for a vertical rice milling machine. Background Technology

[0002] A vertical rice milling machine is a rice processing device with a vertically arranged whitening chamber. Its core structure consists of a feeding hopper, vertical whitening rollers, a rice sieve, and a bran removal system. Driven by a motor, the whitening rollers rotate at high speed within the vertical whitening chamber. Under gravity, the paddy rice enters from the top feed inlet and is subjected to friction, grinding, and compression in the gap between the whitening rollers and the rice sieve, gradually removing the husks and bran to form white rice. Simultaneously, utilizing its vertical structure and with bran removal devices at the bottom or side, the machine separates and removes impurities such as bran powder and broken rice generated during processing using wind or gravity. This achieves continuous processing from paddy rice to finished rice, and is widely used in small and medium-sized grain processing enterprises and rural processing points.

[0003] Currently, in vertical rice milling machines, the screening plate is a key component for separating broken rice, bran, and whole rice grains after rice is crushed. Due to long-term screening, a large amount of residual bran, broken rice debris, and fine impurities accumulate on its surface. If not cleaned in time, it will not only clog the screen holes and affect the screening accuracy, but the accumulation of impurities may also hinder the vibration of the screening plate, reducing processing efficiency. However, the common cleaning method is to manually stop the machine and disassemble the screening plate for cleaning, which is time-consuming and labor-intensive. Although some cleaning devices now have automatic brush cleaning, common cleaning devices are relatively simple. The distance between the brush and the screening plate is usually fixed, and the strength of the brush is not easy to adjust. Utility Model Content

[0025] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0026] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0027] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single embodiment or an embodiment selectively excluded from other embodiments.

[0028] Example 1:

[0029] Reference Figures 1-5 This is the first embodiment of the present invention. This embodiment provides a vertical rice milling machine cleaning device. The vertical rice milling machine cleaning device includes a cleaning component 7. The cleaning component 7 can drive the brush plate 702 to reciprocate to clean the debris blocking the screening plate 6. In conjunction with the setting of the lead screw 707, the brush on the brush plate 702 can penetrate into the interior of the screening plate 6 to achieve the effect of adjusting the cleaning intensity.

[0030] It includes a first operating table 1 and a second operating table 2, and a rice milling device body 3 disposed on the top of the first operating table 1. A protective shell 4 is fixedly connected to the top of the second operating table 2. An extension shell 5 is fixedly connected to one side of the protective shell 4. A screening plate 6 is installed at the bottom of the inner cavity of the protective shell 4. A cleaning component 7 with adjustment function is installed inside the extension shell 5.

[0031] Firstly, the rice milling device body 3 is conveniently installed and fixed via the first operating table 1 and the second operating table 2. It should be noted that the rice milling device body 3 is composed of a DC motor, a transmission wheel, a belt, gears, and rice milling rollers. The principle is that by turning on the DC motor, the transmission wheel is driven to drive the belt, which in turn drives another transmission wheel to rotate the gears. The two gears mesh synchronously and drive the two rice milling rollers rotating inside the protective shell 4 to achieve the rice milling operation. This is existing technology, which is clearly known to those skilled in the art, and will not be elaborated here. The cleaning component 7 is conveniently installed and fixed via the extension shell 5, and the cleaning component 7 can achieve the effect of automatically cleaning the screening plate 6.

[0032] The cleaning component 7 includes a servo motor 701 and a brush plate 702. The servo motor 701 is fixed to one side of the extension shell 5, and the brush plate 702 is disposed inside the protective shell 4. The output end of the servo motor 701 extends into the interior of the extension shell 5 and is fixedly connected to a threaded rod 703. A threaded sleeve 704 is threadedly connected to the surface of the threaded rod 703. An extension plate 705 is fixedly connected to one side of the threaded sleeve 704, and the end of the extension plate 705 away from the threaded sleeve 704 extends into the interior of the protective shell 4.

[0033] By turning on the servo motor 701, the threaded rod 703 is rotated. At this time, the threaded sleeve 704 will drive the extension plate 705 to move between the protective shell 4 and the extension shell 5, which will facilitate the subsequent brushing of the brush plate 702 for cleaning.

[0034] Example 2:

[0035] Reference Figures 4-5 This is the second embodiment of the present invention, which is based on the previous embodiment.

[0036] Specifically, a movable plate 706 is installed on one side of the extension plate 705. A lead screw 707 is threadedly connected inside the movable plate 706. A torsion block 708 is fixedly connected to the top of the lead screw 707. The bottom of the lead screw 707 is rotatably connected to the brush plate 702 through a bearing.

[0037] The movable plate 706 is fixed to the extension plate 705 on one side of its top. When the extension plate 705 moves, it will drive the movable plate 706 to move. The lead screw 707 inside the movable plate 706 will drive the torsion block 708 and the brush plate 702 to achieve the cleaning effect on the screening plate 6. If the user needs to adjust the distance between the brush on the brush plate 702 and the screening plate 6, he can rotate the torsion block 708 to make the lead screw 707 rotate. At this time, the brush plate 702 will gradually descend, allowing the brush to penetrate deeper into the interior of the screening plate 6, thereby increasing the cleaning intensity.

[0038] Specifically, slide rods 718 are fixedly connected to both sides of the top of the brush plate 702. The surface of the slide rods 718 is slidably connected to the inside of the movable plate 706, and a limit ring 709 is fixedly connected to the top of the slide rods 718.

[0039] The sliding connection between the slide bar 718 and the movable plate 706 can improve the stability of the brush plate 702 when it moves up and down.

[0040] Specifically, protective grooves 710 are provided on both sides inside the movable plate 706, and small vibration motors 711 are fixedly connected to both sides inside the brush plate 702.

[0041] The protective groove 710 prevents the small vibrating motor 711 from colliding with the movable plate 706 when the brush plate 702 rises. The small vibrating motor 711 is fixed to the top of the brush plate 702, and its vibration synchronizes with the movement of the brush plate 702. This vibration effectively removes impurities stuck in the screening plate 6 during the cleaning process. The small vibrating motor 711 works by installing eccentric unbalanced weights at both ends of the motor shaft. When the motor is powered on and rotates, the eccentric weights generate periodic unbalanced inertial forces due to centrifugal force, causing the motor and connected equipment to vibrate continuously. The vibration frequency is determined by the motor speed, while the amplitude can be changed by adjusting the weight or relative angle of the eccentric weights, thus converting electrical energy into directional mechanical vibration energy. This method is widely used in screening, conveying, and compaction processes requiring small-amplitude, high-frequency vibration.

[0042] Specifically, a slider 712 is fixedly connected to one side of the top of the movable plate 706, and a slide rail 713 fixed to the inner wall of the protective shell 4 is slidably connected to the surface of the slider 712.

[0043] By sliding the slider 712 and the slide rail 713, the side of the movable plate 706 away from the threaded rod 703 can be evenly stressed and moved, preventing the possibility of jamming during the translation process, and ensuring the strength of the movable plate 706 at the same time.

[0044] Specifically, one side of the top of the movable plate 706 is fixed to the extension plate 705 with screws, and one end of the threaded rod 703 is rotatably connected to the inner wall of the extension shell 5 through a bearing.

[0045] The movable plate 706 and the extension plate 705 are fixed by screws, which makes it easy to disassemble the movable plate 706 and the brush plate 702 for maintenance or replacement. A bearing is provided at one end of the threaded rod 703, which can assist it to rotate on the inner wall of the extension shell 5.

[0046] Example 3:

[0047] Reference Figures 4-5 This is the third embodiment of the present invention, which is based on the first two embodiments.

[0048] Specifically, a limiting groove 8 is provided on one side inside the protective shell 4 and the extension shell 5, and a guide plate 9 is fixedly connected to one side inside the protective shell 4.

[0049] By setting the limiting groove 8, the extension plate 705 can be limited to move. By fixing the guide plate 9 to one side of the inner wall of the protective shell 4, the brush plate 702 and the top position of the movable plate 706 can be blocked to prevent the material from falling directly onto the movable plate 706 and causing damage during the rice milling process.

[0050] Specifically, a first door panel 10 is hinged to one side of the interior of the protective shell 4, and a first latch 11 is installed between one side of the first door panel 10 and the protective shell 4.

[0051] The first door panel 10 and the first latch 11 facilitate the pushing of impurities generated during the cleaning of the brush plate 702 to one side of the protective shell 4 for easy centralized cleaning.

[0052] Specifically, an inspection door panel 12 is hinged to the other side inside the protective shell 4, and a second latch 13 is installed between one side of the inspection door panel 12 and the protective shell 4.

[0053] The installation of the inspection door panel 12 and the second latch 13 facilitates the adjustment of the height between the brush plate 702 and the screening plate 6 by turning the torsion block 708 to rotate the lead screw 707.

[0054] A reinforcing block 14 is fixedly connected to the top of the extension shell 5, and one side of the reinforcing block 14 is fixedly connected to the protective shell 4.

[0055] By fixing the reinforcing block 14 between the extension shell 5 and the protective shell 4, the connection strength between the two can be improved, ensuring the stability of the extension shell 5 for long-term use.

[0056] In use, the material first falls through the top of the protective shell 4 into the interior of the protective shell 4, and then the rice milling device 3 performs the rice milling operation. At this time, impurities in the material, such as bran powder and broken rice, will remain on the top of the screening plate 6. If the user needs to clean it, first open the second lock 13, and rotate the torsion block 708 to make the screw 707 rotate. At this time, the brush plate 702 will gradually descend. As the brush plate 702 moves, it will drive the slide bar 718 to slide within the movable plate 706, thereby allowing the brush to penetrate deeper into the interior of the screening plate 6, thus increasing the cleaning intensity. Then, turn on the small vibration motor 711 and simultaneously turn on the servo motor 701 to make the threaded rod 703 rotate. At this time, the threaded sleeve 704 on the surface of the threaded rod 703 will... The extension plate 705 is moved and limited within the limiting groove 8. As the extension plate 705 moves, the movable plate 706, in conjunction with the lead screw 707, moves the brush plate 702. The servo motor 701 drives the brush plate 702 to reciprocate and clean the screening plate 6. When the screening plate 6 moves, the top side also drives the slider 712 to move within the slide rail 713, ensuring that the side of the movable plate 706 away from the threaded rod 703 can be evenly stressed and moved. At this time, easily cleanable impurities fall directly from the screening plate 6, while larger impurities are pushed to one side of the first door plate 10 by the brush plate 702. If it is necessary to remove them for cleaning, the first latch 11 is released to facilitate the removal of the concentrated impurities, thus completing the automatic cleaning work.

[0057] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
