[0023] like Figure 1-3 As shown, the impurity removal mechanism of a rice grinder proposed in the present invention includes a box body 1, the top of the box body 1 is connected to a feed pipe 2, the top of the feed pipe 2 is connected to a discharge funnel 3, and a magnetic attraction structure 4 is provided inside the feed pipe 2.

[0024] In the present invention, rice can be added into the box body 1 through the feeding pipe 2 and the discharge funnel 3, and metal chips in the rice can be removed through the magnetic attraction structure 4.

[0025] In an optional embodiment, the magnetic structure 4 includes a first guide plate 401, two electromagnetic plates 402, a second guide plate 403, a material receiving box 404, a limit assembly 405, a connecting plate 406, a drive assembly 407 and a guide assembly 408. The first guide plate 401 is arranged on the left side wall of the inner cavity of the feed pipe 2, and the second guide plate 403 is arranged on the right side wall of the inner cavity of the feed pipe 2. The two electromagnetic plates 402 are respectively arranged on the top of the first guide plate 401 and the second guide plate 403. The box 404 is arranged on the right side of the feed pipe 2 and penetrates into the interior thereof. The material receiving box 404 is slidingly connected to the feed pipe 2 and is adapted to the feed pipe 2. The limiting assembly 405 is arranged on the outer end face of the material receiving box 404. The connecting plate 406 is arranged on the right side of the material receiving box 404. The driving assembly 407 is arranged on the top of the box body 1. The output end of the driving assembly 407 is connected to the connecting plate 406. The guide assembly 408 is arranged on the top of the box body 1. The output end of the guide assembly 408 is connected to the connecting plate 406.

[0026] It should be noted that the first guide plate 401 is located above the second guide plate 403. When rice enters the feed pipe 2 through the discharge funnel 3, the rice will first fall above the first guide plate 401, and the metal chips in the rice will be adsorbed by the electromagnetic plate 402 above the first guide plate 401.

[0027] In addition, the right side of the first guide plate 401 is located above the second guide plate 403, the right side of the first guide plate 401 is tilted downward, and the left side of the second guide plate 403 is tilted downward. The tilt of the first guide plate 401 allows the rice to slide automatically, and the sliding rice will fall on the top of the second guide plate 403, and then the electromagnetic plate 402 of the second guide plate 403 will adsorb the metal chips in the rice again, and finally the tilted second guide plate 403 will allow the rice to fall into the interior of the box 1.

[0028] Among them, after the rice is cleaned, the material receiving box 404 can be moved to the left through the connecting plate 406, the driving component 407 and the guide component 408, so that the material receiving box 404 moves to the bottom of the second guide plate 403. At this time, the two electromagnetic plates 402 are closed, and the two electromagnetic plates 402 lose their magnetism. The metal chips will slide downward under the action of gravity. Under the action of the first guide plate 401 and the second guide plate 403, the metal chips will slide into the inside of the material receiving box 404, which is convenient for collecting and cleaning the metal chips adsorbed by the two electromagnetic plates 402. The material receiving box 404 can be limited by the limiting component 405 to ensure the stability of the movement of the material receiving box 404.

[0029] In an optional embodiment, the limiting assembly 405 includes two limiting blocks 4051 and two limiting grooves 4052. The two limiting blocks 4051 are respectively arranged on the front and back of the material receiving box 404, and the two limiting grooves 4052 are respectively opened on the front and rear side walls of the inner cavity of the feeding pipe 2. The right sides of the two limiting grooves 4052 are connected to the outside world, and the two limiting blocks 4051 are respectively slidably connected to the two limiting grooves 4052.

[0030] It should be noted that the two limiting blocks 4051 and the two limiting grooves 4052 can limit and guide the receiving box 404, ensuring the movement stability of the receiving box 404 while preventing the receiving box 404 from shaking and rotating during movement.

[0031] In an optional embodiment, the drive assembly 407 includes two first fixed plates 4071, a drive servo motor 4072, a threaded rod 4073 and a first connecting block 4074. The two first fixed plates 4071 are both arranged at the top of the box body 1, the drive servo motor 4072 is arranged on the left side of the left first fixed plate 4071, the left end of the threaded rod 4073 is arranged on the output shaft of the drive servo motor 4072, the right end of the threaded rod 4073 is rotatably connected to the left side of the right first fixed plate 4071, the first connecting block 4074 is sleeved on the outside of the threaded rod 4073, the first connecting block 4074 is threadedly connected to the threaded rod 4073, and the back of the first connecting block 4074 is connected to the front of the connecting plate 406.

[0032] It should be noted that when the driving servo motor 4072 is started, the output shaft of the driving servo motor 4072 will drive the threaded rod 4073 to rotate. Since the back of the first connecting block 4074 is connected to the front of the connecting plate 406, the first connecting block 4074 will not rotate. When the threaded rod 4073 rotates, under the action of the threaded thrust, the threaded rod 4073 will drive the first connecting block 4074 to move to the left or right, the first connecting block 4074 will drive the connecting plate 406 to move to the left or right, and the connecting plate 406 will drive the material receiving box 404 to move to the left or right.

[0033] In an optional embodiment, the guide assembly 408 includes two second fixed plates 4081, a guide rod 4082 and a second connecting block 4083. The two second fixed plates 4081 are both arranged at the top of the box body 1, the guide rod 4082 is arranged between the opposite sides of the two second fixed plates 4081, the second connecting block 4083 is sleeved on the outer side of the guide rod 4082, the second connecting block 4083 is slidingly connected to the guide rod 4082, and the front of the second connecting block 4083 is connected to the back of the connecting plate 406.

[0034] It should be noted that when the connecting plate 406 moves to the left or right, the connecting plate 406 will drive the second connecting block 4083 to move to the left or right, and the second connecting block 4083 can slide on the outside of the guide rod 4082 to guide the connecting plate 406, thereby ensuring the stability of the movement of the connecting plate 406, thereby further ensuring the stability of the movement of the material receiving box 404.

[0035] In an optional embodiment, a dust removal mechanism 5 is provided inside the box body 1 , a filtering mechanism 6 is provided inside the box body 1 , and a collection mechanism 7 is provided inside the box body 1 .

[0036] It should be noted that the dust removal mechanism 5 can remove dust from the rice, the filtering mechanism 6 can filter solid impurities in the rice, and the collecting mechanism 7 can collect the filtered rice.

[0037] In an optional embodiment, a controller is provided on the outer end surface of the box body 1, and the two electromagnetic plates 402, the driving servo motor 4072, the dust removal mechanism 5 and the filtering mechanism 6 are all electrically connected to the controller, and the two electromagnetic plates 402, the driving servo motor 4072, the dust removal mechanism 5 and the filtering mechanism 6 can be controlled by the controller.

[0038] Working principle:

[0039] When the impurity removal mechanism of the rice mill is in use, the two electromagnetic plates 402 are started. When the rice enters the feed pipe 2 through the discharge funnel 3, the rice will first fall onto the top of the first guide plate 401, and the electromagnetic plate 402 above the first guide plate 401 will absorb the metal chips in the rice. The first guide plate 401 is tilted to make the rice slide down automatically, and the slid rice will fall onto the top of the second guide plate 403, and the electromagnetic plate 402 of the second guide plate 403 will absorb the metal chips in the rice again. Finally, the tilted second guide plate 403 will make the rice fall into the interior of the box 1. After the rice impurity removal is completed, the servo motor 4072 is started, and the output shaft of the servo motor 4072 drives the threaded rod 4073 to rotate. Under the action of threaded thrust, the threaded rod 4073 will drive the first connecting block 4074 to move to the left, and the first connecting block 4074 will drive the connecting plate 406 to move to the left, and the connecting plate 406 will drive the material receiving box 404 to move to the left, so that the material receiving box 404 moves to the bottom of the second guide plate 403. At this time, the two electromagnetic plates 402 are closed, and the two electromagnetic plates 402 lose their magnetism. The metal chips will slide downward under the action of gravity. Under the action of the first guide plate 401 and the second guide plate 403, the metal chips will slide into the inside of the material receiving box 404, which is convenient for collecting and cleaning the metal chips adsorbed by the two electromagnetic plates 402. When the collection is completed, the servo motor 4072 is started in reverse to make the material receiving box 404 move to the right, and the collected metal chips are discharged from the feed pipe 2.

[0040] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
