Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention. The present invention will be further described below in conjunction with the embodiments.

[0040] Please refer to Figures 1 - 4, in an embodiment of the present application, a rice polishing machine includes a polishing box 1, a base 3, a controller 4, and a feed hopper 2. The polishing box 1 is disposed on the base 3, the controller 4 is disposed on the base 3, the feed hopper 2 is disposed on the polishing box 1 and the two are in communication. A discharge port is provided on the polishing box 1. The polishing machine further includes a polishing system disposed on the polishing box 1 for polishing rice; wherein

[0041] The polishing system includes:

[0042] An execution module, which is a set and symmetrically disposed in the polishing box 1 for performing polishing actions; and

[0043] A driving module, which is disposed on the polishing box 1 and connected to the execution module for controlling the operation of the execution module.

[0044] In a specific case of this embodiment, the execution module includes:

[0045] A moving seat 10, which is movably disposed on the polishing box 1 and elastically connected therebetween. The moving seat 10 is connected to the driving module;

[0046] Polishing rollers 12, which are several in number and equidistantly movably disposed on the moving seat 10;

[0047] Driving discs 11, which are the same in number as the polishing rollers 12 and are both movably disposed on the moving seat 10. The driving discs 11 are coaxially connected to the polishing rollers 12; and

[0048] Damping strips 9, which are disposed in the polishing box 1 and are in sliding fit with the driving discs 11.

[0049] In another specific case of this embodiment, a polishing sleeve 13 is sleeved on the polishing roller 12.

[0050] It should be noted that, in this embodiment, the position of the moving seat 10 can be adjusted by using a linear motor or an electric cylinder, which will not be listed one by one here.

[0051] In actual application, rice is poured into the feed hopper 2 and falls into the polishing box 1. By controlling the operation of the driving module, the moving seat 10 is driven to reciprocate along the vertical direction, and the moving directions of the two side moving seats 10 are opposite. During this process, under the sliding fit between the driving disc 11 and the damping strip 9, the driving disc 11 and the polishing roller 12 are driven to rotate, so as to polish the passing rice. Finally, the polished rice is discharged from the discharge port to complete the polishing process of the rice.

[0052] Please refer to Figure 1 、 Figure 2 and Figure 4, as another preferred embodiment of the present application, the driving module includes:

[0053] The position-adjusting seat 5, one end of which is hinged to the polishing box 1, and guide grooves 6 are symmetrically formed on the position-adjusting seat 5;

[0054] The sliding column 7 is arranged at one end of the moving seat 10 and is in sliding fit with the guide groove 6;

[0055] The threaded rod 15 is movably arranged on the polishing box 1 and is in threaded fit therebetween. One end of the threaded rod 15 is connected to the other end of the position-adjusting seat 5 through a connector 16;

[0056] The power element. The polishing box 1 is movably arranged on the machine base 17. The power element is arranged on the machine base 17, and the output end of the power element is connected to the threaded rod 15.

[0057] It should be particularly noted that the power element can be replaced by a stepping motor 14 or a servo motor. In this embodiment, the power element is preferably the stepping motor 14. The stepping motor 14 is arranged on the machine base 17 and its output end is connected to the threaded rod 15. As for the specific model parameters of the stepping motor 14, the best choice can be made according to the actual situation and will not be listed one by one here.

[0058] In actual application, the controller 4 controls the stepping motor 14 to be energized and continuously switch between positive and reverse rotations to drive the threaded rod 15 to rotate. Under the action of the threaded fit between the threaded rod 15 and the polishing box 1, the threaded rod 15 can be driven to reciprocate up and down in the vertical direction, thereby driving the position-adjusting seat 5 to swing along its hinge point. Thus, under the cooperation of the guide groove 6 and the sliding column 7, the moving seat 10 is driven to reciprocate in the vertical direction, so as to perform the polishing work on the rice.

[0059] Please refer to Figures 1 - 4 , as another preferred embodiment of the present application, the rice polishing machine further includes a dust suction module arranged on the polishing box 1 for sucking the dust in the polishing box 1; wherein

[0060] The dust suction module includes:

[0061] The dust suction seat 8 is arranged in the polishing box 1;

[0062] The dust suction box 23 is arranged on the base 3; and

[0063] The air extraction assembly is connected between the dust suction box 23 and the dust suction seat 8 for discharging the air in the polishing box 1 into the dust suction box 23.

[0064] In a specific case of this embodiment, the air extraction assembly includes:

[0065] An air extraction box 18 is provided on the polishing box 1. An input hole 20 and an output hole 21 are provided on the air extraction box 18. One-way valves 19 are provided in both the input hole 20 and the output hole 21. The input hole 20 and the output hole 21 are respectively communicated with the dust suction seat 8 and the dust suction box 23; and

[0066] A piston 22 is movably arranged in the air extraction box 18 and is connected to one of the moving seats 10.

[0067] In another specific case of this embodiment, a scraper 24 is movably arranged in the dust suction box 23. The scraper 24 is elastically connected to the dust suction box 23, and the scraper 24 is connected to the other moving seat 10.

[0068] During the reciprocating movement of one of the moving seats 10, the piston 22 is driven to reciprocate along the air extraction box 18, so as to suck the dust generated during the polishing process in the polishing box 1 into the air extraction box 18 along the dust suction seat 8, and finally discharge the dust in the air extraction box 18 into the water in the dust suction box 23 along the output hole 21. At the same time, during the reciprocating movement of the other moving seat 10, the scraper 24 can be driven to reciprocate in the dust suction box 23, so as to prevent the dust from adsorbing on the inner wall of the dust suction box 23, and there is no need for manual cleaning by the staff.

[0069] The working principle of this application:

[0070] Pour the rice into the feeding funnel 2 and let it fall into the polishing box 1. Through the controller 4, the stepping motor 14 is controlled to be energized and continuously switch between forward and reverse rotations to drive the threaded rod 15 to rotate. Under the screw-thread matching effect between the threaded rod 15 and the polishing box 1, the threaded rod 15 can be driven to reciprocate up and down along the vertical direction, so as to drive the positioning seat 5 to swing along its hinge, and thus under the cooperation between the guide groove 6 and the sliding column 7, the moving seat 10 is driven to reciprocate along the vertical direction. Through the sliding cooperation between the driving disc 11 and the damping strip 9, the driving disc 11 and the polishing roller 12 are driven to rotate, so as to perform the polishing work on the passing rice. Finally, the polished rice is discharged from the discharge port, and the polishing work of the rice is completed. During the reciprocating movement of one of the moving seats 10, the piston 22 is driven to reciprocate along the air extraction box 18, so as to suck the dust generated during the polishing process in the polishing box 1 into the air extraction box 18 along the dust suction seat 8, and finally discharge the dust in the air extraction box 18 into the water in the dust suction box 23 along the output hole 21. At the same time, during the reciprocating movement of the other moving seat 10, the scraper 24 can be driven to reciprocate in the dust suction box 23, so as to prevent the dust from adsorbing on the inner wall of the dust suction box 23, and there is no need for manual cleaning by the staff.
