[0018] The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit its scope.

[0019] Example

[0020] Please see Figures 1-5This utility model discloses a device for removing impurities and stones in rice processing, comprising an L-shaped support plate 1, a removal barrel 2, and a motor 10. A vertical plate 3 is fixedly connected to the front of the inner bottom end of the L-shaped support plate 1. Guide sleeves 4 are fixedly installed at the center of both ends of the removal barrel 2. Two sets of guide rods 5 are fixedly connected between the rear end of the vertical plate 3 and the rear end of the inner side of the L-shaped support plate 1. The two sets of guide rods 5 are symmetrically distributed on the left and right sides of the removal barrel 2. The two sets of guide sleeves 4 are slidably fitted onto the two sets of guide rods 5. A material inlet is opened at the top of the removal barrel 2, and a barrel cover 6 is installed on the rotating cover of the material inlet. The bottom of the removal barrel 2 is bucket-shaped, and a drain is connected to the bottom. Inside the material pipe 7 and the impurity removal barrel 2, coarse-hole screen 8 and fine-hole screen 9 are arranged sequentially from top to bottom. The motor 10 is fixedly installed at the top of the impurity removal barrel 2. A connecting plate 11 is fixedly connected to the output shaft of the motor 10. A connecting shaft 12 is fixedly installed on the top edge of the connecting plate 11. A transmission rod 13 is rotatably mounted on the connecting shaft 12. A fixing rod 14 is fixedly connected to the middle of the inner rear end of the L-shaped support plate 1. The end of the transmission rod 13 away from the connecting shaft 12 is rotatably connected to the front end of the fixing rod 14. Two sets of rack rods 15 are fixedly connected between the rear end of the vertical plate 3 and the inner rear end of the L-shaped support plate 1. The impurity removal barrel 2 is slidably fitted on the two sets of rack rods. On rod 15, two sets of rack rods 15 are respectively located above the coarse-pore sieve plate 8 and the fine-pore sieve plate 9. Multiple sets of teeth are equidistantly arranged at the middle of the right end of each set of rack rods 15. A stirring shaft 16 is rotatably mounted at the center of the bottom inner side of both the coarse-pore sieve plate 8 and the fine-pore sieve plate 9. Gears 18 are fixedly sleeved at the top of each of the two stirring shafts 16, and the two gears 18 mesh with the teeth on the two sets of rack rods 15. Multiple sets of stirring blades 17 are fixedly fixed in a ring at equal intervals on each of the two stirring shafts 16. In use, by opening the lid 6, the rice to be impurities removed is poured into the impurity removal bucket 2. By starting the motor 10, the motor 10 can drive the impurity removal bucket 2. The back-and-forth movement causes the impurity removal tank 2 to move back and forth, which in turn drives the coarse-hole sieve plate 8 and the fine-hole sieve plate 9 to move back and forth, thereby shaking and sieving the rice in the impurity removal tank 2. When the coarse-hole sieve plate 8 and the fine-hole sieve plate 9 move back and forth, the stirring shaft 16 will rotate back and forth under the meshing of the gear 18 and the right end tooth of the rack 15. This causes the stirring shaft 16 to drive the stirring blade 17 to rotate, and the rice is stirred by the rotation of the stirring blade 17. Through the shaking and sieving of the coarse-hole sieve plate 8 and the fine-hole sieve plate 9 and the stirring of the stirring blade 17, the impurity removal efficiency of the rice can be accelerated, the impurity removal effect can be improved, and the practicality can be enhanced.

[0021] The impurity removal barrel 2 has two sets of inlet / outlet openings on its right end, symmetrically distributed on the upper and lower sides of the guide sleeve 4. Both the coarse-hole screen 8 and the fine-hole screen 9 have a fixed sealing cap 19 on their right ends. The coarse-hole screen 8 and the fine-hole screen 9 are movably installed inside the impurity removal barrel 2 through the cooperation of the sealing cap 19 and the inlet / outlet openings. The top of the inlet / outlet opening is higher than the top of the gear 18. A handle 20 is fixed in the middle of the right end of each of the two sets of sealing caps 19. Locks 21 are provided between the right ends of both sets of sealing caps 19 and the right end of the impurity removal barrel 2. In use, after the coarse-hole screen 8 and the fine-hole screen 9 are installed inside the impurity removal barrel 2, the sealing cap 19 is placed on the inlet / outlet and fixed by the locks 21. After impurity removal, the coarse-hole screen 8 and the fine-hole screen 9 can be removed by opening the locks 21 and holding the handles 20. Since the top of the inlet / outlet is higher than the top of the gear 18, the gear 18 will not interfere during removal / outlet operation.

[0022] The impurity removal bucket 2 has two sets of observation ports symmetrically arranged on the left side, and each set of observation ports is equipped with an observation window 22. By setting the observation window 22, it is easy to observe the impurity removal status of the rice in the impurity removal bucket 2 so that it can be taken out in time.

[0023] Two sets of reinforcing plates 23 are symmetrically fixedly connected between the front end of the upright plate 3 and the bottom inner side of the L-shaped support plate 1; by setting the reinforcing plates 23, the connection between the upright plate 3 and the L-shaped support plate 1 can be made more firm and stable.

[0024] This utility model discloses a device for removing impurities and stones in rice processing. Its working principle is as follows: During use, the lid 6 is opened, and the rice to be removed is poured into the removal bucket 2. The motor 10 is started, causing the connecting plate 11 to rotate. The connecting plate 11, through the connecting shaft 12, drives the transmission rod 13 to swing. During this swinging motion, the transmission rod 13 causes the removal bucket 2 to move back and forth under the guidance of the guide sleeve 4 and the guide rod 5. This, in turn, causes the removal bucket 2 to move the coarse-hole sieve 8 and the fine-hole sieve 9 back and forth, thus shaking and sieving the rice inside the removal bucket 2. Furthermore, the back-and-forth movement of the coarse-hole sieve 8 and the fine-hole sieve 9 drives the stirring shaft 16 forward. The reciprocating motion causes the stirring shaft 16 to rotate during movement through the meshing of the gear 18 and the upper teeth of the rack 15. This, in turn, causes the stirring shaft 16 to drive the stirring blades 17 to rotate, thus stirring the rice. After shaking and stirring, larger stones and debris remain on the coarse-hole screen 8, while the rice and smaller stones and debris fall onto the fine-hole screen 9. After further shaking and sieving through the fine-hole screen 9, the rice remains on the fine-hole screen 9, while the smaller stones and debris fall to the bottom of the L-shaped support plate 1 and are discharged through the discharge pipe 7. After the impurity removal is completed, the coarse-hole screen 8 and the fine-hole screen 9 are removed from the impurity removal bucket 2, and the stones and rice can be poured out separately.

[0025] The present invention relates to a device for removing impurities and stones in rice processing. Its installation, connection, or setting methods are all common mechanical methods, and any method that can achieve its beneficial effects can be implemented. The motor 10 and the locking buckle 21 of the device for removing impurities and stones in rice processing are commercially available. Technical personnel in this industry only need to install and operate it according to the accompanying instruction manual.

[0026] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
