Description

Technical Field

[0001] The present application relates to the technical field of rice processing, and particularly relates to a rice hull suction device for rice processing. Background Art

[0002] Rice processing is to roll and remove the rice hulls on the surface of paddy through a huller, and then remove the relatively light rice hulls and dust through negative pressure, leaving the internal rice grains. The rice hulls and dust are discharged and can be processed into bran for feed processing. After the paddy is processed by rolling and hulling, a rice hull suction device is also needed to perform rice hull suction treatment on the rolled and hulled paddy, that is, to separate the rice from the rice hulls and dust. After retrieval, the patent document with the authorization announcement number CN220696840U discloses a dust-absorbing rice processing rice hull suction device, including a main body of the rice hull suction device for rice processing. A device frame is arranged at the bottom of the main body of the rice hull suction device for rice processing. A rice filtering box mechanism is arranged above the device frame, and a dust suction mechanism is arranged below the rice filtering box mechanism; the rice filtering box mechanism includes a rice filtering box unit and a stirring and dispersing unit, and the rice filtering box unit is arranged on the upper surface of the device frame.

Therefore, continuous rice hull suction treatment operation cannot be achieved, and it is not suitable for the rice hull suction treatment of a large quantity of rolled and hulled paddy, and the working efficiency is relatively low.

[0004] Therefore, we propose a rice hull suction device for rice processing to solve the above problems. Utility Model Content

Detailed implementation manners

[0027] The technical solutions of the present application will be clearly and completely described below in conjunction with specific embodiments. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present application without creative efforts shall fall within the protection scope of the present application.

[0028] Refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 , the present application provides a rice hull suction device for rice processing, including a box body 1. A feed hole 2 is opened at the left top of the box body 1 for adding the paddy after rolling and hulling into the interior of the box body 1. A rice outlet hole 3 is opened at the right bottom of the box body 1 for discharging the rice after removing the rice hulls. Among them:

[0029] On the left side wall of the box body 1, a U-shaped conveying frame 4 is fixedly installed. The right side of the U-shaped conveying frame 4 penetrates through the feeding hole 2. A conveyor belt 5 is rotatably installed in the U-shaped conveying frame 4. The conveyor belt 5 is used to convey the rice after rolling and husking into the box body 1. A material lifting mechanism and a husk suction mechanism are arranged on the box body 1. The material lifting mechanism is used to lift the rice entering the box body 1 upward. The material lifting mechanism includes a rotating shaft 7, a plurality of arc-shaped material lifting plates 8 and a motor 9. The rotating shaft 7 is rotatably installed in the box body 1 and is located below the first guide plate 6. A plurality of arc-shaped material lifting plates 8 are fixedly installed on the rotating shaft 7 and are distributed in an equidistant annular manner. The motor 9 is fixedly installed on the front outer wall of the box body 1. The output shaft end of the motor 9 extends into the box body 1 and is fixedly connected to the front end of the rotating shaft 7. The first motor 9 is used to control the rotation of the rotating shaft 7 and a plurality of arc-shaped material lifting plates 8. By using the centrifugal force generated when a plurality of arc-shaped material lifting plates 8 rotate, the rice after rolling and husking entering the inside of the box body 1 can be first lifted to the space in the upper right direction, and then the rice after rolling and husking automatically falls under its own weight, which can improve the separation effect of rice husks, dust and rice. It should be added that the number of a plurality of arc-shaped material lifting plates 8 can be set to 4-7. The husk suction mechanism is used to suck away the rice husks in the rice. The husk suction mechanism includes a dust suction fan 10, a dust suction main pipe 11, three dust suction branch pipes 12, three baffle nets 13, a dust discharge pipe 14 and a dust collection box 15. The dust suction fan 10 is fixedly installed on the top of the box body 1. The dust suction main pipe 11 is fixedly connected to the suction end of the dust suction fan 10.

The dust discharge pipe 14 is fixedly installed on the discharge end of the dust suction fan 10. The dust collection box 15 is fixedly installed on the left outer wall of the box body 1 and is located below the U-shaped conveying frame 4. One end of the dust discharge pipe 14 is fixedly communicated with the top of the dust collection box 15. By using the suction force generated when the dust suction fan 10 operates, the rice husks and dust can be sucked into the dust collection box 15 for temporary storage. The rice falls downward and is discharged from the rice outlet 3. The baffle net 13 can block and intercept the rice grains to prevent the rice grains from entering the dust suction branch pipes 12. By arranging three baffle nets 13 and three dust suction branch pipes 12, the rice husks can be sucked away more comprehensively and thoroughly.

[0030] In this embodiment, in order to make all the rice after rolling and husking conveyed on the conveyor belt 5 smoothly fall into the box body 1, a first guide plate 6 is fixedly installed on the right side of the U-shaped conveying frame 4, and the first guide plate 6 is inclined.

And the left side surfaces of the three material blocking nets 13 are flush with the right inner wall of the box body 1. By using the sliding connection and cooperation of the electric sliding seat 22 on the electric guide rail 21, the vertical lifting of the scraping strip 23 can be controlled. The rice grains adsorbed on the left surface of the material blocking net 13 can be scraped off by the scraping strip 23, so as to avoid the blockage of the mesh holes on the material blocking net 13 by the rice grains, and further maintain the effective air permeability of the material blocking net 13.

[0032] In this embodiment, in order to enhance the stability of the U-shaped conveying frame 4 and also to enhance the stability of the dust collecting box 15, an L-shaped support seat 16 is fixedly installed on the left outer wall of the box body 1. One side of the L-shaped support seat 16 far away from the box body 1 is fixedly connected to the bottom of the U-shaped conveying frame 4. The bottom of the dust collecting box 15 is fixedly connected to the L-shaped support seat 16.

[0033] In this embodiment, in order to facilitate the cleaning of the rice husks and dust collected in the dust collecting box 15, a cleaning port is opened on the front side wall of the dust collecting box 15. A cleaning door 17 is fixedly installed on the front side wall of the dust collecting box 15 by screws.

[0034] In this embodiment, in order to ensure the smooth discharge of the air entering the dust collecting box 15 and to ensure that the rice husks and dust in the dust collecting box 15 will not be discharged outside the dust collecting box 15, air permeation holes are opened on the cleaning door 17, and dust blocking nets 18 are fixedly installed in the air permeation holes.

[0035] In this embodiment, in order to ensure that all the paddy rice after rolling and hulling entering the interior of the box body 1 falls on the arc-shaped material lifting plate 8, a vertical partition plate 19 located on the left side of the arc-shaped material lifting plate 8 is fixedly installed on the bottom inner wall of the box body 1. The top of the vertical partition plate 19 is fixedly connected to the right side of the bottom of the U-shaped conveying frame 4.

[0036] In this embodiment, in order to ensure that all the rice grains smoothly discharge from the rice outlet hole 3, a second material guiding plate 20 located below the arc-shaped material lifting plate 8 is fixedly installed on the left side wall of the vertical partition plate 19. The second material guiding plate 20 is inclined, and the right side of the second material guiding plate 20 penetrates through the rice outlet hole 3.

[0037] In this embodiment, the motor 9, the dust suction fan 10, the electric guide rail 21 and the electric sliding seat 22 can all be purchased in the market. The motor 9, the dust suction fan 10, the electric guide rail 21 and the electric sliding seat 22 are configured with power supplies. Their circuit connection methods and control methods belong to the mature technologies in this field, so as to be fully disclosed and explained. Therefore, no further description will be given in this article.

[0038] With the above structure, when the rice hulling device provided by the present application is in use, by continuously conveying the roller-hulled paddy into the interior of the box body 1, under the combined action of the material lifting mechanism and the hull suction mechanism, the rice hulls and dust can be comprehensively and effectively sucked into the dust collection box 15 for temporary storage, and the rice grains can be discharged from the rice outlet hole 3. Furthermore, continuous hull suction treatment operations can be achieved, improving work efficiency. During specific operations, start the motor 9 and the dust suction fan 10 to run, and then place the roller-hulled paddy on the conveyor belt 5. The conveyor belt 5 can be used to continuously convey the roller-hulled paddy into the box body 1. By using the motor 9 to drive the rotating shaft 7 and multiple arc-shaped material lifting plates 8 to rotate, under the centrifugal force generated when the multiple arc-shaped material lifting plates 8 rotate, the roller-hulled paddy entering the interior of the box body 1 can be first lifted to the space in the upper right direction, and then the roller-hulled paddy automatically falls under its own weight, which can improve the separation effect of the rice hulls and the rice. During the process of the roller-hulled paddy being lifted and then falling, the baffle net 13 can be used to block the rice grains from entering the dust suction branch pipe 12. By using the suction force generated when the dust suction fan 10 runs, the rice hulls and dust can be sucked into the three dust suction branch pipes 12, and the rice hulls and dust then pass through the dust suction main pipe 11, the dust suction fan 10, and the dust discharge pipe 14 in sequence and enter the dust collection box 15. When the clean rice grains fall onto the second guide plate 20, they then slope downward and are discharged from the rice outlet hole 3. Furthermore, by continuously conveying the roller-hulled paddy into the box body 1 using the conveyor belt 5, continuous hull suction treatment operations can be realized, and it is particularly suitable for the hull suction treatment of a large quantity of roller-hulled paddy.
