When the gear rod 34 rotates, the front side gear 32 will rotate clockwise, and the rear side gear 32 will rotate counterclockwise.

[0035] like Figure 1 , Figure 2 , Figure 3 , Figure 5 and Figure 6As shown, the screening mechanism 4 includes a screen plate 41, a wedge block 42, a top block 43, a first fan 44, an inclined plate 45, a second fan 46, a first spring 47, a packaging shell 48 and a first slide bar 49. The screen plate 41 is slidably connected to the middle of the right side of the box body 1. The screen plate 41 passes through the right part of the box body 1, and the right part of the screen plate 41 is inclined toward the lower right. The top block 43 is connected in the middle of the gear rod 34, and the wedge block 42 is slidably connected to the upper right side of the box body 1. The top of the wedge block 42 contacts the top block 43, and the bottom of the wedge block 42 contacts the right side of the screen plate 41. The top block 43 rotates to squeeze the wedge block 42, so that the wedge block 42 moves downward, and the wedge block 42 squeezes the right side of the top of the screen plate 41, so that the screen plate 41 moves to the left, and the lower part of the box body 1 Two first sliding bars 49 are connected to the right side of the box body 1, the sieve plate 41 is slidably connected to the first sliding bars 49, first springs 47 are wound around the first sliding bars 49, left and right ends of the first springs 47 are respectively connected to the first sliding bars 49 and the bottom of the sieve plate 41, a first fan 44 is symmetrically connected to the middle of the right wall inside the box body 1, the first fan 44 is located at the upper right side of the sieve plate 41, a packaging shell 48 is connected to the left side of the upper inner part of the box body 1, a shell outlet is opened at the front lower part of the shell 48, a plurality of inclined plates 45 are connected inside the packaging shell 48, a plurality of second fans 46 are rotatably connected to the front upper part of the packaging shell 48, the first fan 44 blows air to the left side, and the second fan 46 sucks air from the rear side, and they cooperate with each other to suck the outer shell of the rice into the packaging shell 48.

[0036] When people need to husk the rice, first, start the first motor 33, the output shaft of the first motor 33 drives the gear rod 34 to rotate, thereby driving the front and rear side gears 32 to rotate, and then driving the front and rear pressing wheels 31 to rotate inward, then turn on the first fan 44 and the second fan 46, and then pour the rice from the feed port of the box body 1, the pressing wheel 31 crushes the rice to separate the rice husk from the rice grains, and the rice husk and the rice grains fall on the sieve plate 41 below, and because the gear rod 34 is rotating, The top block 43 is driven to rotate, and the top block 43 contacts and squeezes the top of the wedge block 42, so that the wedge block 42 moves downward, and the bottom of the wedge block 42 squeezes the top right side of the screen plate 41 downward, so that the screen plate 41 moves to the left, and the first spring 47 is compressed. When the top block 43 rotates and separates from the top of the wedge block 42, the first spring 47 is reset, thereby driving the screen plate 41 to move to the right and reset, and the top right side of the screen plate 41 squeezes the bottom of the wedge block 42, so that the wedge block 42 moves upward and resets, and the top block 43 rotates continuously with The top of the wedge block 42 contacts and separates, so that the sieve plate 41 continuously moves left and right. At this time, the rice grains will continuously fall into the storage box 2 below due to the shaking of the sieve plate 41. The shaking of the sieve plate 41 can fully separate the unseparated rice husks on the rice, which is beneficial to improving the rice separation effect and improving the rice quality. A handle is connected to the right side of the storage box 2, which is convenient for people to draw out the storage box 2. The first fan 44 on the right blows the light rice husk to the left, and cooperates with the second fan 46 on the left to suck the rice husk into the packaging shell 48 along the inclined plate 45. The rice husk falls out from the lower front side of the packaging shell 48, thereby quickly and effectively realizing the screening and separation of the rice husk and the rice grains. When people do not need to shell the rice, turn off the first motor 33, the first fan 44 and the second fan 46, the top block 43 no longer rotates, and the first spring 47 resets to drive the sieve plate 41 to reset, and then drives the wedge block 42 to reset. At this time, people draw the storage box 2 to the right, put away the shelled rice grains, and then put them back into the storage box 2.

[0037] Embodiment 2, on the basis of embodiment 1, as Figure 1 , Figure 2 , Figure 3 , Figure 7 and Figure 8 As shown, it also includes a quantitative mechanism 5, which includes a placement box 51, a support frame 52, a baffle 53 and a second spring 54. The support frame 52 is connected to the lower right side of the box body 1, and the placement box 51 is connected to the support frame 52. A discharge port is opened at the lower left side of the placement box 51, and a baffle 53 is slidably connected to the upper left side of the support frame 52. The upper part of the baffle 53 blocks the discharge port of the placement box 51. The rotation of the top block 43 will squeeze the baffle 53, so that the baffle 53 moves upward, so that the baffle 53 no longer blocks the discharge port of the placement box 51. 54 is wrapped around the front and rear sides of the upper left part of 52, and the upper and lower ends of 54 are respectively connected to 52 and 53.

[0038] In order to prevent the pressure wheel 31 from being unable to fully crush the rice for husking due to too much rice being poured in, after people pour the rice into the placement box 51, when the top block 43 rotates, the top block 43 will contact the baffle 53 and press the bottom of the baffle 53 upward, so that the baffle 53 moves upward, and the second spring 54 is compressed. At this time, the upper part of the baffle 53 no longer blocks the discharge port of the placement box 51, and the rice falls from the placement box 51 into the feed port of the box body 1 through the discharge port of the placement box 51. When the top block 43 rotates to separate from the bottom of the baffle 53, the second spring 54 is reset, thereby driving the baffle 53 to move downward and reset. The upper part of the baffle 53 blocks the discharge port of the placement box 51, and the rice no longer falls. The top block 43 rotates to continuously contact and separate from the bottom of the baffle 53, so that the upper part of the baffle 53 continuously opens and blocks the discharge port of the placement box 51, so that the rice intermittently falls into the feed port of the box body 1, realizing the timed and quantitative discharge of the rice, so that the rice is fully crushed.

[0039] like Figure 2 , Figure 3 and Fig. 9 As shown, it also includes a selection mechanism 6, which includes a third spring 61, a screen frame 62, a second motor 63, a cam 64 and a fourth spring 65. The second motor 63 is installed in the middle of the rear side of the box body 1, and the output shaft of the second motor 63 is connected to the cam 64. The screen frame 62 is slidably connected to the lower part of the box body 1, and a space is left between the right part of the screen frame 62 and the right part of the box body 1. The middle part of the screen frame 62 is tilted toward the lower right, and the lower part of the screen frame 62 is tilted toward the lower left. The screen frame 62 is located below the screen plate 41, and the cam 64 is in contact with the screen frame 62. The fourth spring 65 is wound on both sides of the front and rear of the lower left part of the screen frame 62, and the upper and lower ends of the fourth spring 65 are respectively connected to the screen frame 62 and the box body 1, and the third spring 61 is wound on both sides of the front and rear of the lower right part of the screen frame 62, and the upper and lower ends of the third spring 61 are respectively connected to the screen frame 62 and the box body 1.

[0040] In order to select the hulled rice grains, people first start the second motor 63, the output shaft of the second motor 63 drives the cam 64 to rotate, the cam 64 presses the left side of the lower rear part of the screen frame 62 downward, so that the screen frame 62 moves downward, the third spring 61 on the left side is slightly compressed, and the fourth spring 65 on the right side is compressed. When the cam 64 rotates and separates from the right side of the lower part of the screen frame 62, the third spring 61 and the fourth spring 65 are reset, thereby driving the screen frame 62 to reset. When the cam 64 rotates continuously, the screen frame 62 vibrates up and down under the action of the cam 64, the third spring 61 and the fourth spring 65. When the hulled rice grains fall from the sieve plate 41, the rice grains will fall on the sieve frame 62. The vibration of the sieve frame 62 will cause the small particles of rice to fall from the small holes, and then slide from the lower part of the sieve frame 62 into the left side of the bottom of the box body 1, while the large particles of rice fall from both sides of the sieve frame 62 into the storage box 2, so as to select the hulled rice grains. When people stop husking the rice, turn off the second motor 63.

[0041] like Figure 3 and Fig.10 As shown, it also includes a prying mechanism 7, which includes a connecting block 71, a fifth spring 72, a push column 73 and a second slide bar 74. The second slide bar 74 is connected to the front and rear sides of the middle part of the box body 1, and a connecting block 71 is slidably connected between the right sides of the front and rear second slide bars 74. The upper right side of the connecting block 71 contacts the left side of the sieve plate 41. The movement of the sieve plate 41 to the left will drive the connecting block 71 to move to the left. Several push columns 73 are connected to the left and right sides of the bottom of the connecting block 71. The push columns 73 are located above the sieve frame 62 and close to the sieve frame 62. The fifth spring 72 is connected between the front and rear parts of the left side of the connecting block 71 and the left side of the adjacent second slide bar 74.

[0042] In order to select the shelled rice grains more quickly, when the sieve plate 41 moves to the left, the connecting block 71 is driven to move to the left, thereby driving the push post 73 to move to the left, and the fifth spring 72 is compressed. When the sieve plate 41 moves to the right, the fifth spring 72 is reset, thereby driving the connecting block 71 to move to the right and reset, thereby driving the push post 73 to move to the right. When the sieve plate 41 continues to move left and right, the connecting block 71 will also move left and right under the action of the sieve plate 41 and the fifth spring 72, thereby driving the push post 73 to move left and right. The push post 73 pries the rice grains on the sieve frame 62 back and forth, so that rice grains of different sizes can be separated faster.

[0043] like Figure 2 , Figure 3 , Fig.11 and Fig.12As shown, it also includes a raking mechanism 8, which includes a connecting plate 81, a moving block 82, a guide rod 83 and a sixth spring 84. Two guide rods 83 are connected to the lower sides of the front and rear walls of the storage box 2, and two guide rods 83 are slidably connected to the upper sides of the front and rear walls of the storage box 2. Four moving blocks 82 are slidably connected between the lower guide rods 83, and the upper parts of the moving blocks 82 are connected to the upper guide rods 83. The upper parts of the moving blocks 82 are connected to the upper guide rods 83. The upper left part of the rightmost moving block 82 is connected to a connecting plate 81, the top of the connecting plate 81 contacts the bottom of the wedge block 42, the connecting plate 81 is slidably connected to the box body 1, and the front and rear sides of the lower left part of the leftmost moving block 82 are connected to the left wall of the storage box 2 by a sixth spring 84.

[0044] In order to prevent the rice grains from piling up too high and contacting the box body 1 when the storage box 2 is pulled out, causing the rice grains to spill, it is necessary to make the rice fall evenly in the storage box 2. When the wedge block 42 moves downward, the bottom of the wedge block 42 presses the top of the connecting plate 81 downward, causing the connecting plate 81 to move to the left, thereby driving the moving block 82 on the right to move to the left, and then the remaining moving blocks 82 move to the left through the upper guide rod 83, and the sixth spring 84 is compressed. When the wedge block 42 moves upward, the sixth spring 84 is reset and drives the moving block 82 to move to the right, thereby the remaining moving blocks 82 move to the right through the upper guide rod 83, and then the connecting plate 81 is moved to the right and reset. When the wedge block 42 continues to move up and down, the moving block 82 also continues to move left and right under the action of the connecting plate 81 and the sixth spring 84, thereby raking the rice grains in the storage box 2 to prevent the rice grains from piling up too high.
