Description

Technical Field

[0001] The utility model relates to the technical field of rice processing, in particular to a rice dandruff removing device for rice processing. Background Art

[0002] Rice dandruff removal is an important link in the rice production process, aiming to remove impurities such as dust, debris and rice husks in rice. Traditional rice dandruff removal equipment mainly removes impurities by mechanical screening.

[0003] The existing rice dandruff removing device imports a batch of rice mixed with crushed residues into the chassis through a hopper and filters out the crushed residues to achieve the effect of dandruff removal;

[0004] However, when the rice after dandruff removal in the chassis is exported, it is necessary to close the feeding hopper to prevent the rice without dandruff removal from being mixed with the rice. In this way, when exporting the dandruff-removed rice, it is necessary for workers to intermittently open and close the hopper and the material guiding port in an alternating manner. The back-and-forth opening and closing operation by workers is extremely inconvenient, and it affects the filtering time efficiency of the subsequent dandruff-removed rice imported into the chassis, thus affecting the overall efficiency of rice dandruff removal. Content of the Utility Model

[0005] The purpose of the utility model is to provide a rice dandruff removing device for rice processing, which can synchronously control the opening and closing of the feeding hopper and the material guiding port, reduce the manual process of opening and closing the hopper and the material guiding port back and forth, and at the same time, enable the subsequent dandruff-removed rice to be continuously imported, thereby improving the overall efficiency of rice dandruff removal.

[0006] To achieve the above purpose, the utility model provides the following technical solution: A rice dandruff removing device for rice processing, including a chassis, a hopper, and a filter screen. A front end plate is fixedly installed on the front of the chassis. The hopper is communicated with the top of the chassis. A servo motor is fixedly installed on the front of the front end plate. The output end of the servo motor is fixedly connected with a connecting shaft. A plurality of connecting plates are fixedly installed at equal intervals on the outer circumference of the connecting shaft. A filter plate is fixedly installed on the side of the connecting shaft away from the connecting shaft. A movable plate is slidably installed on one side outside the chassis. A control motor is installed on one side of the circumferential surface of the chassis. The output end of the control motor is fixedly connected with a transmission gear. A rack is fixedly installed on the outside of the movable plate. The outer edge of the transmission gear meshes with the outer edge of the rack.

[0007] Preferably, brackets are respectively fixedly installed on both sides of the chassis. A first receiving box and a second receiving box are symmetrically inserted and fixed near the brackets on both sides of the chassis.

[0008] Preferably, an opening groove is formed through one side of the chassis. The movable plate slides in the inner wall of the opening groove, and the opening groove extends into the inner cavity of the hopper.

[0009] Preferably, the filter screen is integrally formed with the inner wall of the chassis, and the filter screen and the opening groove correspond to the second material receiving box and the first material receiving box respectively.

[0010] Preferably, the connecting plate is attached to the inner cavity of the chassis, and the filter holes on the surface of the filter plate are larger than the diameter of the filter holes on the surface of the filter screen.

[0011] Preferably, a connecting seat is fixedly installed at the edge of the circumferential surface of the chassis, and the control motor is fixedly installed on the connecting seat on one side.

[0012] Compared with the prior art, the beneficial effects of the present utility model are:

[0013] In the present utility model, through the periodic operation of the control motor, the driving gear periodically drives the arc-shaped rack, so that the arc-shaped movable plate can slide reciprocally at intervals around the opening groove. When the rice is exported at the first material receiving box, it can separate the rice mixed with debris and the rice with dandruff removed that is re-introduced at the hopper. After the rice with dandruff removed is dialed into the first material receiving box by the connecting plate, the movable plate separates from one side of the inner cavity of the hopper, so that the accumulated rice in the hopper can be continuously introduced into the chassis. In this way, the manual operation of opening and closing the hopper and the material guiding port back and forth is reduced. At the same time, the subsequent rice with dandruff removed is continuously introduced, thereby improving the overall dandruff removal efficiency of the rice.

[0014] In the present utility model, the rice mixed with debris is introduced into the chassis through the hopper. The batch of introduced rice is separated by multiple groups of connecting plates and filter plates. The servo motor drives the connecting shaft, the connecting plate and the filter plate to rotate circumferentially, so that the rice in the chassis can be stirred, so that the debris mixed in the rice at each interval of the connecting plate can pass through the surface of the filter screen and be filtered into the second material receiving box, and the filtered rice can be guided into the first material receiving box by opening the opening groove at the first material receiving box. Such an operation can separate the batch of rice in the chassis and achieve a better filtering effect for the debris mixed in the batch of rice. BRIEF DESCRIPTION OF THE DRAWINGS

Specific implementation mode

[0020] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. The described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments.

[0021] Please refer to Figures 1-4 , the present invention provides a technical solution: a rice dandruff removal device for rice processing, including a chassis 1, a hopper 13, and a filter screen 5. A front end plate 11 is fixedly installed on the front of the chassis 1. The hopper 13 is communicated with the top of the chassis 1. A servo motor 3 is fixedly installed on the front of the front end plate 11. The output end of the servo motor 3 is fixedly connected with a connecting shaft 31. Connecting plates 32 are fixedly installed at equal intervals on the outer circumference of the connecting shaft 31. A filter plate 33 is fixedly installed on the side of the connecting shaft 31 away from the connecting shaft 31. A movable plate 4 is slidably installed on one side of the outside of the chassis 1;

[0022] A control motor 7 is installed on one side of the circumferential surface of the chassis 1. The output end of the control motor 7 is fixedly connected with a transmission gear 72. A rack 8 is fixedly installed on the outside of the movable plate 4. The outer edge of the transmission gear 72 meshes with the outer edge of the rack 8;

[0023] The rice mixed with debris is introduced into the chassis 1 through the hopper 13. The rice introduced in batches is separated by multiple groups of connecting plates 32 and filter plates 33. The servo motor 3 drives the connecting shaft 31, the connecting plates 32, and the filter plate 33 to rotate circumferentially, so that the rice in the chassis 1 can be stirred, so that the debris mixed in the rice separated by each group of connecting plates 32 can pass through the surface of the filter screen 5 and enter the second material receiving box 21. The filtered rice can be led to the first material receiving box 2 by opening the opening groove 6 at the first material receiving box 2. Such an operation can separate the rice in batches in the chassis 1, achieving a better filtering effect for the debris mixed in the batch of rice;

[0024] By controlling the periodic operation of the motor 7, the transmission gear 72 periodically drives the arc-shaped rack 8, enabling the arc-shaped movable plate 4 to reciprocate slidingly at intervals within the opening slot 6. When the rice is exported at the first material receiving box 2, it can separate the rice mixed with debris and the de-dandruff rice re-introduced at the hopper 13. After the de-dandruff rice is toggled into the first material receiving box 2 by the connecting plate 32, the movable plate 4 separates from one side of the inner cavity of the hopper 13, so that the rice accumulated in the hopper 13 can be continuously introduced into the chassis 1. This reduces the manual operation of opening and closing the hopper 13 and the material guiding port back and forth. At the same time, it enables the subsequent continuous introduction of de-dandruff rice, thereby improving the overall de-dandruff efficiency of the rice.

[0025] Wherein, brackets 12 are fixedly installed on both sides of the chassis 1 respectively. Symmetrically inserted and fixed near the brackets 12 on both sides of the chassis 1 are the first material receiving box 2 and the second material receiving box 21 respectively. The servo motor 3 drives the connecting shaft 31, the connecting plate 32 and the filter plate 33 to rotate circumferentially, so as to stir the rice in the chassis 1, enabling the debris mixed in the rice at intervals of each group of connecting plates 32 to pass through the surface of the filter screen 5 and be filtered into the second material receiving box 21, while the filtered rice can be led into the first material receiving box 2 by opening the opening slot 6 at the first material receiving box 2.

[0026] Wherein, an opening slot 6 runs through one side of the chassis 1, and the movable plate 4 slides within the inner wall of the opening slot 6, and the opening slot 6 extends into the inner cavity of the hopper 13. The arc-shaped movable plate 4 can reciprocate slidingly at intervals within the opening slot 6. When the rice is exported at the first material receiving box 2, it can separate the rice mixed with debris and the de-dandruff rice re-introduced at the hopper 13. After the de-dandruff rice is toggled into the first material receiving box 2 by the connecting plate 32, the movable plate 4 separates from one side of the inner cavity of the hopper 13, so that the rice accumulated in the hopper 13 can be continuously introduced into the chassis 1. This reduces the manual operation of opening and closing the hopper 13 and the material guiding port back and forth.

[0027] Wherein, the filter screen 5 is integrally formed with the inner wall of the chassis 1, and the filter screen 5 and the opening slot 6 respectively correspond to the second material receiving box 21 and the first material receiving box 2 one by one. The connecting plate 32 fits with the inner cavity of the chassis 1. The filter holes on the surface of the filter plate 33 are larger than the diameter of the filter holes on the surface of the filter screen 5. The size of the rice is larger than the diameter of the filter holes on the surface of the filter screen 5. The diameter of the filter holes on the surface of the filter plate 33 is smaller than the diameter of the rice. The size of the arc-shaped rack 8 matches the size of the part of the movable plate 4 at the bottom of the hopper 13. The arc-shaped movable plate 4 can reciprocate slidingly at intervals within the opening slot 6, and can adjust the intervals of the part of the movable plate 4 blocked at the first material receiving box 2 and the part of the movable plate 4 blocked at the hopper 13, so as to synchronously control the opening and closing at the hopper 13 and the material guiding port, reducing the manual operation of opening and closing the hopper 13 and the material guiding port back and forth.

[0028] Among them, a connecting seat 71 is fixedly installed at the edge of the circumferential surface of the chassis 1, and the control motor 7 is fixedly installed on the connecting seat 71 on one side. By the periodic operation of the control motor 7, the driving gear 72 periodically drives the arc-shaped rack 8, so that the arc-shaped movable plate 4 can slide back and forth at intervals in the opening groove 6.

[0029] Working principle: When removing debris mixed in rice, the rice mixed with debris is first introduced into the chassis 1 through the hopper 13;

[0030] Then, the rice introduced in batches is separated by multiple groups of connecting plates 32 and filter plates 33. The servo motor 3 drives the connecting shaft 31, the connecting plates 32 and the filter plates 33 to rotate circumferentially, so as to stir the rice in the chassis 1, so that the debris mixed in the rice separated by each group of connecting plates 32 can pass through the surface of the filter screen 5 and enter the second receiving box 21;

[0031] Then, by the periodic operation of the control motor 7, the driving gear 72 periodically drives the arc-shaped rack 8, so that the arc-shaped movable plate 4 can slide back and forth at intervals in the opening groove 6, so that the filtered rice can be led to the first receiving box 2 by opening the opening groove 6 at the first receiving box 2.

[0032] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes and modifications can be made to these embodiments without departing from the principle of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
