The mechanical equipment used is called a rice milling machine.

[0003] A Chinese patent discloses a rice mill (authorization announcement number CN209317731U). The patented technology uses high-temperature hot air fluidization treatment to make the brown rice cortex brittle and produce cracks, while not destroying the natural shape of the brown rice, making the brown rice cortex easy to peel off, and has a good effect in removing the brown rice cortex. The resulting polished rice has better cooking quality.

[0023] Reference Figure 1 - Figure 5 As shown, in this embodiment: both ends of the shell 8 are provided with a slide groove 14, and the inside of the slide groove 14 is slidably connected with a slider 15, and the other end of the slider 15 is fixedly connected to the movable plate 11. By setting the structure of the slide groove 14 and the slider 15, the moving direction of the movable plate 11 can be restricted to avoid tilting and improve the stability of the movable plate 11 when moving.

[0024] Reference Figure 1 - Figure 3 As shown, in the present embodiment: a first spring 16 is fixedly connected to the interior of the shell 8, and the other end of the first spring 16 is fixedly connected to the movable plate 11. By setting the first spring 16, after the elliptical plate 10 rotates, the rebound force of the first spring 16 is utilized to push the movable plate 11 to drive the limiting rod 12 to disengage from the interior of the limiting groove 13, thereby playing an auxiliary movement role. At the same time, when the position of the adjustment rail 6 is fixed, the position of the limiting rod 12 can be limited by the action force of the first spring 16.

[0025] Reference Figure 1 - Figure 3 As shown, in this embodiment: the difference between the maximum diameter and the minimum diameter of the elliptical plate 10 is greater than the distance that the limiting rod 12 is inserted into the limiting groove 13. When the elliptical plate 10 rotates ninety degrees, it no longer blocks the movable plate 11. At this time, the moving distance of the movable plate 11 can make the limiting rod 12 disengage from the inside of the limiting groove 13.

[0026] Reference Figure 1 , Figure 4 and Figure 5 As shown, in this embodiment: the interior of the rotating rod 9 is slidably connected with a slide bar 19, the end of the slide bar 19 away from the rotating rod 9 passes through the shell 8 and is fixedly connected with a knob 20, one side of the knob 20 is fixedly connected with an insertion rod 21, and the end of the insertion rod 21 away from the knob 20 is snap-fitted with the shell 8, and the insertion rod 21 is driven outward by pulling the knob 20 to move the slide bar 19 outward.

[0027] Reference Figure 1 , Figure 4 and Figure 5 As shown, in this embodiment: travel grooves 22 are provided at both ends of the interior of the rotating rod 9, and a travel block 23 is slidably connected to the interior of the travel groove 22, and the other end of the travel block 23 is fixedly connected to the slide bar 19. By setting the structure of the travel groove 22 and the travel block 23, the moving trajectory of the slide bar 19 can be restricted to prevent the user from using too much force when pulling the knob 20, causing the slide bar 19 to escape from the interior of the rotating rod 9.

[0028] Reference Figure 1 , Figure 4 and Figure 5As shown, in this embodiment: a second spring 24 is fixedly connected to the inside of the rotating rod 9, and the other end of the second spring 24 is fixedly connected to the sliding rod 19. Feeding plates 25 are provided on both sides of the rice milling machine body 1, and a sieve plate 26 is installed at the bottom of the feeding plate 25 inside the rice milling machine body 1. By providing the second spring 24, the force of the second spring 24 is utilized to limit the position of the insertion rod 21 when the position of the knob 20 is fixed, so as to prevent the device from shaking and causing the insertion rod 21 to be separated from the inside of the shell 8, affecting the fixing effect of the adjustment rail 6. Then, by providing the structure of the feeding plate 25 and the sieve plate 26, the milled rice and bran are separated, so as to ensure that the milled rice is clean and free of impurities and transported to the inside of the broken rice collection box 4.

[0029] Working principle: when it is necessary to adjust the position of the rice milling roller 7, the elliptical plate 10 is driven to rotate by rotating the rotating rod 9, so that the elliptical plate 10 no longer blocks the movable plate 11. At this time, the movable plate 11 drives the limiting rod 12 to disengage from the inside of the limiting groove 13. The user can pull the adjusting rail 6 to drive the rice milling roller 7 to adjust the gap between the two rice milling rollers 7, so as to achieve the required milling force and improve the rice milling quality. The operation is simple and convenient, which reduces the labor intensity of the user and improves the work efficiency. By setting the structure of the slide groove 14 and the slider 15, the moving direction of the movable plate 11 can be limited to avoid tilting and improve the stability of the movable plate 11 when moving. By setting the first spring 16, after the elliptical plate 10 rotates, the rebound force of the first spring 16 is used to push the movable plate 11 to drive the limiting rod 12 to disengage from the inside of the limiting groove 13, which plays an auxiliary movement role. At the same time, when the position of the adjusting rail 6 is fixed, the position of the limiting rod 12 can be limited by the force of the first spring 16. When the elliptical plate 10 rotates ninety degrees, The movable plate 11 is no longer blocked. At this time, the moving distance of the movable plate 11 can make the limiting rod 12 disengage from the inside of the limiting groove 13. By pulling the knob 20, the insertion rod 21 is driven to move outward, so that the slide bar 19 moves outward. At this time, the user can turn the knob 20 to make the rotating rod 9 drive the elliptical plate 10 to rotate, and the position of the adjustment rail 6 can be quickly adjusted, so as to achieve the required rolling force. By setting the structure of the travel groove 22 and the travel block 23, the moving trajectory of the slide bar 19 can be limited to avoid the user from pulling When the knob 20 is turned, excessive force is applied, causing the slide bar 19 to disengage from the interior of the rotating rod 9. By providing a second spring 24 and utilizing the force of the second spring 24, the position of the insertion rod 21 can be restricted when the position of the knob 20 is fixed, thereby preventing the device from shaking and causing the insertion rod 21 to disengage from the interior of the housing 8, thereby affecting the fixing effect of the adjustment rail 6. Then, by providing a structure of a feed plate 25 and a screen plate 26, the milled rice and bran are separated, ensuring that the milled rice is clean and free of impurities and is transported to the interior of the broken rice collection box 4.
