Technical Field
[0001] The utility model relates to the field of rice processing machines, and specifically to an organic rice screening and impurity removing machine. Background Technique
[0002] Organic rice refers to rice grown by using natural and organic planting methods and completely adopting natural farming methods. Organic rice must be a high-quality rice variety recommended by the planting improvement field, and chemical fertilizers, pesticides, growth regulators, etc. cannot be used during the cultivation process.
[0003] During the rice production and processing process, a large amount of rice bran and gravel impurities are often mixed in. At this time, an impurity removing device is needed to screen and remove impurities from the rice. Some impurity removing machines screen the rice by setting a sieve mesh. However, most sieve meshes are fixed, which easily leads to the accumulation of more rice on the sieve mesh. It takes a long time to filter through the sieve mesh, and rice bran and other impurities will adhere to the rice. During the rice screening process, the impurities adhering to the rice are difficult to fall off naturally. Therefore, this method often fails to remove impurities completely. Moreover, when some rice is screened, it may be clumped. If it is not broken up, it will affect the subsequent rice screening effect. In view of this, we propose an organic rice screening and impurity removing machine. Summary of the Utility Model

[0020] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present utility model.
[0021] Please refer to Figures 1-4 As shown in the figure, this embodiment provides an organic rice screening and impurity removing machine, which includes a machine body 1. A sieve plate 2 is slidably connected to the inner wall of the machine body 1, and a vibration mechanism 3 is rotatably connected to the inner wall of the machine body 1, which is used to drive the sieve plate 2 to move up and down to improve the screening efficiency of the device. A dispersion mechanism 4 is fixedly connected to the top of the machine body 1, which is used to disperse the agglomerated rice entering the inside of the machine body 1 to facilitate subsequent screening of the rice.
[0022] The improvement of this embodiment lies in:
[0023] During the production and processing of rice, a large amount of rice bran and gravel impurities are often mixed in. At this time, a cleaning device is needed to screen and remove impurities from the rice. Some cleaning machines screen the rice by setting up a sieve mesh. However, most sieve meshes are fixed, which easily leads to the accumulation of a large amount of rice on the sieve mesh when it falls. It takes a long time to filter through the sieve mesh, and rice bran and other impurities will adhere to the rice. During the screening process of the rice, the impurities adhering to the rice are difficult to fall off naturally. Therefore, this method often results in incomplete impurity removal. In addition, when some rice is screened, it is clumped. If it is not broken up, it will affect the subsequent screening effect of the rice. In view of this, we propose an organic rice screening and impurity removal machine. Therefore, a vibration mechanism 3 is set up, which can not only improve the screening efficiency of the device, but also shake off the impurities adhering to the rice while driving the rice to shake, improving the impurity removal effect. And a dispersion mechanism 4 is set up, which can break up the clumped rice and improve the subsequent screening effect of the device.
[0024] Considering the need to improve the screening efficiency of the device, the structure of the vibration mechanism 3 is further disclosed as follows Figure 2 and Figure 3 As shown, the vibration mechanism 3 includes a rotating rod 31 rotatably connected to the inner wall of the machine body 1, and one side of the rotating rod 31 penetrates through the rear wall of the machine body 1. A driving motor 32 is fixedly installed on the side of the rotating rod 31 penetrating through the machine body 1. Starting the driving motor 32 drives the rotating rod 31 to rotate. A hollow column 33 is fixedly connected to the bottom of the sieve plate 2. A sliding rod 34 is slidably connected inside the hollow column 33. One side of the rotating rod 31 located inside the machine body 1 is rotatably connected to a connecting rod 35, and the side of the connecting rod 35 away from the rotating rod 31 is rotatably connected to the sliding rod 34. When the rotating rod 31 rotates, it pulls the connecting rod 35 to move up and down, thereby driving the sliding rod 34 to move up and down inside the hollow column 33. When the sliding rod 34 moves upward, the top of the sliding rod 34 abuts against the inner top of the hollow column 33, thereby driving the hollow column 33 to move upward, and further driving the sieve plate 2 to move upward. When the sliding rod 34 moves downward, it moves downward under the self-weight of the sieve plate 2, realizing the up and down movement of the sieve plate 2, thereby driving the rice above the sieve plate 2 to shake. This not only improves the screening efficiency of the device, but also continuously shakes the rice, which can shake off the impurities adhering to the rice and improve the use effect of the device.
[0025] Considering the need to break up the clumped rice, the structure of the dispersion mechanism 4 is further disclosed as follows Figure 4As shown in the figure, the dispersion mechanism 4 includes a stirring box 41 fixedly installed on the top of the machine body 1. The discharge port of the stirring box 41 penetrates through the inner top of the machine body 1. Through the feed hopper of the stirring box 41, the rice to be sieved is conveyed into the inside of the stirring box 41. A first stirring rod 42 is rotatably connected to the inner top of the stirring box 41, and the top of the first stirring rod 42 penetrates through the top of the stirring box 41. Two support plates 43 are fixedly connected to the top of the stirring box 41. A worm 44 is rotatably connected to the support plates 43, and one side of the worm 44 penetrates through the support plates 43. A worm gear 45 is fixedly connected to the side of the first stirring rod 42 that penetrates through the stirring box 41, and the worm gear 45 is meshed with the worm 44. The rotation of the worm 44 drives the meshing transmission of the worm gear 45, thereby driving the rotation of the first stirring rod 42 to stir and disperse the rice inside the stirring box 41. A leakage plate 47 is fixedly connected to the inner wall of the stirring box 41. Leakage holes are provided above the leakage plate 47, and the diameter of the leakage holes is relatively large, facilitating the falling of rice and impurities, etc. The dispersed rice passes through the leakage plate 47 and falls above the sieve plate 2.
[0026] Considering that it is necessary to drive the operation of the dispersion mechanism 4, a belt 46 is sleeved on one side of the rotating rod 31 located outside the machine body 1, and the side of the belt 46 away from the rotating rod 31 is sleeved on one side of the worm 44. While the rotating rod 31 rotates, in cooperation with the belt 46, the worm 44 in the dispersion mechanism 4 is driven to rotate.
[0027] Considering that it is necessary to improve the dispersing effect of the dispersion mechanism 4 on the clumped rice, a fixed block 5 is fixedly connected to the inner top of the stirring box 41. A second stirring rod 6 is rotatably connected to the inner bottom of the fixed block 5. The bottom of the second stirring rod 6 penetrates through the bottom of the fixed block 5, and the second stirring rod 6 is rotatably connected to the first stirring rod 42. A first bevel gear 7 is fixedly connected to the outer wall of the first stirring rod 42. When the first stirring rod 42 rotates, it drives the rotation of the first bevel gear 7. A second bevel gear 8 is fixedly connected to the outer wall of the second stirring rod 6. An auxiliary bevel gear 9 is rotatably connected to one side of the inner wall of the fixed block 5, and the upper and lower sides of the auxiliary bevel gear 9 are respectively meshed with the first bevel gear 7 and the second bevel gear 8. The rotation of the first bevel gear 7 drives the rotation of the auxiliary bevel gear 9, thereby driving the rotation of the second bevel gear 8, and further driving the rotation of the second stirring rod 6, so that the first stirring rod 42 and the second stirring rod 6 rotate in opposite directions, making the stirring effect of the device on the rice better and further improving the dispersing effect on the rice.
[0028] In order to remove the rice bran in the rice, a collection box 10 is fixedly connected to the top of the machine body 1. A suction fan is fixedly installed inside the collection box 10. One side of the collection box 10 close to the dispersion mechanism 4 is communicated with a conduit 11, and the side of the conduit 11 away from the collection box 10 is communicated with the inner top of the machine body 1. While the rice is being sieved, the suction fan is started. When the sieve plate 2 drives the rice to shake up and down, the lifted rice bran and dust, etc. can be sucked out through the suction fan and drawn into the collection box 10 in cooperation with the conduit 11.
[0029] To export impurities and the like, a diversion plate 12 is fixedly connected to the bottom of the sieve plate 2, and one side of the diversion plate 12 penetrates through the side wall of the machine body 1. The rice bran and fine impurities remaining above the sieve plate 2 can leak out from the filter holes of the sieve plate 2 when the sieve plate 2 vibrates up and down. The leaked rice bran and fine impurities fall onto the upper part of the diversion plate 12 and flow out through the diversion plate 12. A plurality of chutes are formed in the inner wall of the machine body 1, and sliders 13 are slidably connected in the chutes. The side of the slider 13 away from the chute is fixedly connected to the side of the sieve plate 2 adjacent to the diversion plate 12. By providing the sliders 13, when the sieve plate 2 moves up and down, the sliders 13 are driven to move in the chutes, providing stability and guidance for the up and down movement of the sieve plate 2.
[0030] When the organic rice screening and impurity removing machine of the present utility model is in specific use, first, the rice to be screened is conveyed into the mixing box 41 through the feed hopper of the mixing box 41. Then, the driving motor 32 is started to drive the rotating rod 31 to rotate. Cooperating with the belt 46, the worm 44 is driven to rotate, thereby driving the worm gear 45 to engage and drive, and further driving the first stirring rod 42 to rotate to stir and disperse the rice in the mixing box 41. When the first stirring rod 42 rotates, it drives the first bevel gear 7 to rotate, thereby driving the auxiliary bevel gear 9 to rotate, and further driving the second bevel gear 8 to rotate. The rotation of the second bevel gear 8 drives the second stirring rod 6 to rotate in the opposite direction. The first stirring rod 42 and the second stirring rod 6 rotate in opposite directions, making the stirring effect of the device on the rice better and further improving the dispersion effect of the rice. The dispersed rice passes through the leakage plate 47 and the discharge port of the mixing box 41 and falls onto the upper part of the sieve plate 2;
[0031] While the rotating rod 31 rotates, the connecting rod 35 is pulled to move up and down, thereby driving the sliding rod 34 to move up and down inside the hollow column 33. When the sliding rod 34 moves upward, the top of the sliding rod 34 abuts against the inner top of the hollow column 33, thereby driving the hollow column 33 to move upward, and further driving the sieve plate 2 to move upward. When the sliding rod 34 moves downward, it moves downward under the self - weight of the sieve plate 2, realizing the up and down movement of the sieve plate 2, thereby driving the rice above the sieve plate 2 to shake, so that the rice bran and fine impurities remaining above the sieve plate 2 can leak out from the filter holes of the sieve plate 2. The leaked rice bran and fine impurities fall onto the upper part of the diversion plate 12 and flow out through the diversion plate 12. The plump rice above the sieve plate 2 falls through the sieve plate 2 to the bottom of the machine body 1 and can be output later by opening the discharge port at the bottom of the machine body 1.

Those skilled in the art should understand that the present utility model is not limited by the above embodiments, and the above embodiments and the descriptions in the specification are only preferred examples of the present utility model, and are not used to limit the present utility model.
