[0042] For the circuits, electronic components, and module mechanisms involved, etc., existing technologies are adopted, which can be fully realized by those skilled in the art without further elaboration. The content protected by this application does not involve improvements to software, circuits, and methods either.
[0043] Working principle: When using the rice milling device for rice processing, first, connect the power supply. Put the rice to be processed into the box body 1 through the hopper 11, and start the driving motor 13. The driving motor 13 drives one of the rice milling rollers 12 to rotate. Since the transmission gears 14 of adjacent two rice milling rollers 12 are meshed with each other, therefore, multiple rice milling rollers 12 rotate synchronously under the transmission of the transmission gears 14, and then perform operations such as rice milling and hulling on the rice entering the box body 1.
[0044] After the rice milling is completed, the rice falls on the top side of the mounting seat 2 and inside the screen frame 3. The rice falling on the mounting seat 2 will flow into the screen frame 3 by itself. At the same time, start the double-shaft motor 33. The first output shaft of the double-shaft motor 33 drives the turntable 34 to rotate. The turntable 34 drives the left slider 32 to reciprocate in the chute through the rotating pin and the support rod 35. The left slider 32 drives the screen frame 3 to reciprocate on the two mounting seats 2, and then quickly screens the rice in the screen frame 3.
[0045] The second output shaft of the double-shaft motor 33 drives the incomplete gear 46 to rotate. When the teeth of the incomplete gear 46 are meshed with the teeth on the toothed plate 45, it can push the V-shaped plate 4 to slide in the installation groove 201. The V-shaped plate 4 drives the connecting plate 41, the first scraping bar 42, and the second scraping bar 43 to move. The first scraping bar 42 scrapes the rice in the screen frame 3, and the second scraping bar 43 cleans the screen plate 21.
[0046] When the teeth of the incomplete gear 46 are disengaged from the teeth on the toothed plate 45, under the elastic force of the spring 44, the V-shaped plate 4 resets, so as to be able to control the first scraping bar 42 and the second scraping bar 43 to reciprocally scrape the bottom inner wall of the screen frame 3 and the top side of the screen plate 21, which can not only improve the screening efficiency but also prevent the screen frame 3 and the screen plate 21 from being blocked.
[0047] During the rice milling operation, bran dust and the like generated are sucked away through the air duct 15 connected to an external exhaust device or dust collection device, preventing the accumulation of bran dust and the like inside the box body 1. The screened rice is discharged through the third discharge pipe 301, the broken rice and the like separated out are discharged through the second discharge pipe 22, and the rice passing through the sieve frame 3 is discharged through the first discharge pipe 101, thus completing the entire rice milling process.
[0048] The rice milling device provided by the present utility model has a compact structure and is easy to operate. Driven by the dual-axis motor 33, it can simultaneously achieve the reciprocating screening operation of the sieve frame 3 and the reciprocating scraping operations of the first scraping strip 42 and the second scraping strip 43. This not only improves the screening efficiency but also avoids the blockage problems of the sieve frame 3 and the sieve plate 21. At the same time, the bran dust is extracted through the air duct 15, ensuring the cleanliness inside the box body 1. In addition, the device is also provided with the first discharge pipe 101, the second discharge pipe 22, and the third discharge pipe 301, facilitating the separate discharge of rice, broken rice, bran husks, etc., which is convenient for subsequent processing and machining.
[0049] The above has introduced in detail a rice milling device for rice processing provided by the present utility model. Specific embodiments are used in this article to elaborate on the principle and implementation manner of the present utility model. The description of the above embodiments is only used to help understand the method and its core idea of the present utility model. It should be noted that for those of ordinary skill in the art in this technical field, without departing from the principle of the present utility model, several improvements and modifications can still be made to the present utility model, and these improvements and modifications also fall within the protection scope of the claims of the present utility model.
