Description

Technical Field

[0001] The present invention relates to the technical field of rice hullers, and in particular to a smart rice huller capable of realizing flexible processing. Background Art

[0002] Rice processing typically involves cleaning, hulling, milling, grading, and finished product handling. The rice huller, which is part of the rice hulling process, is a grain processing machine that removes the husks from the rice to produce brown rice. As the huller separates the rice into husks and brown rice, the falling husks are screened and removed by air suction. The hulling process involves measuring rice quality metrics such as hulling rate, rough breakage rate, and husk content.

[0003] During the rice hulling process, samples of rough rice are typically collected manually, either periodically or randomly, and then analyzed using a rice quality analyzer. Data such as hulling rate, rough breakage rate, and husk content are then transmitted to the huller's control system to adjust processing parameters and improve rice quality. However, manually collecting samples and analyzing them using a rice quality analyzer is a complex process. Summary of the Invention

[0013] Further arrangement of the present application is that the dust collection cover and the circumferential side of the square shell are provided with a protective mesh cover to prevent the bran from being sucked in.

[0014] In summary, the present application has the following advantages:

[0015] 1. A certain amount of bran sample is extracted by the sampling mechanism at a certain time or at any time, the bran sample is extracted into the online huller quality analyzer by the negative pressure suction mechanism, the shelling rate, the broken rate and the rice hull content of the bran sample are obtained by the huller quality analyzer, and the online detection result is fed back to the control box of the huller body to adjust and optimize the hulling process parameters and improve the hulling quality.

[0016] 2. When the sampling mechanism is used, the piston rod of the driving cylinder is extended and retracted to drive the swing arm to rotate, so that the swing arm drives the rotating shaft of the feeding door to rotate to form an opening for the bran sample to enter the top of the square pipe connector, after a certain amount of bran sample enters, the driving cylinder is reset to close the feeding door, and then the negative pressure suction mechanism is used to input the bran sample in the square round connector into the huller quality analyzer.

[0017] 3. The negative pressure suction mechanism comprises a feeding bin arranged on the feeding pipe of the huller quality analyzer, a suction pipe connected between the feeding bin and the square round connector, a suction machine, and an air outlet pipe connected between the suction machine and the top of the feeding bin, the top of the feeding bin is provided with a filter core to prevent the bran sample from entering the air outlet pipe, when the suction machine works, the bran sample in the square round connector can be extracted to the feeding bin, and the bran sample falls into the feeding pipe of the huller quality analyzer through the filtration of the filter core, and then the bran sample enters the feeding pipe of the huller quality analyzer after the valve at the feeding pipe is opened for online detection.

[0018] 4. When the sampling box is driven by the power assembly to move, when the sampling box moves toward the direction close to the square shell to a set limit state, the grain rough sample enters from the feeding port of the sampling box, and the sealing assembly closes the open end to achieve quantitative sampling; and when the sampling box moves toward the direction away from the square shell to a set limit state, the sealing assembly opens the open end, so that the grain rough sample is extracted by the negative pressure suction mechanism;

[0020] 6. The sealing assembly includes a cover plate and a sealing plug. When the sampling box moves toward the direction close to the square shell to a set limit state, the cover plate is first maintained in a horizontal state under the limit of the sampling box, and then in a vertical state under the action of gravity so that the sealing plug on the cover plate is embedded in the open end of the sampling box. When the sampling box moves toward the direction away from the square shell to a set limit state, the sampling box first drives the cover plate to rotate upward to a horizontal state, and then keeps the cover plate in a horizontal state;

[0021] 7. There is always rough rice output at the unloading position of the rice huller body, and some dust will be raised when unloading at the unloading position of the rice huller body. When the sampling box moves toward the direction close to the square shell and the feeding port is not placed in the square shell, the cover plate is rotated downward to open the connecting pipe opening. At this time, when the suction machine is working, air flows along the dust suction pipe, the negative pressure pipe, and the filter to achieve dust suction and avoid dust. At the same time, due to the setting of the counterweight block on the cover plate, the cover plate is not easy to shake during this process, and the setting of the counterweight block on the cover plate is better when the opening end of the sampling box is sealed. The setting of the connecting pipe opening provides space for storing the counterweight block on the cover plate.

DETAILED DESCRIPTION

[0031] The present invention will be further described in detail below with reference to the accompanying drawings.

[0032] Example 1: A smart rice huller that realizes flexible processing, such as Figures 1 to 3 As shown, the apparatus comprises a rice huller body 1, a control box 2 mounted on the rice huller body 1, a sampling mechanism 3 mounted at the feed port of the rice huller body 1 for removing a sample of rough rice, a rice huller quality analyzer 4 mounted on the rice huller body 1 and connected to the control box 2 for signal transmission, and a negative pressure suction mechanism mounted between the sampling mechanism 3 and a feed pipe 41 of the rice huller quality analyzer 4 for conveying the rough rice sample from the sampling mechanism 3 to the rice huller quality analyzer 4 for online testing. The rice huller quality analyzer 4 performs online testing of the hulling rate, rough crushing rate, and husk content of the rough rice sample, and feeds back the online test results to the control box 2 of the rice huller body 1, thereby adjusting and optimizing the rice hulling process parameters and improving the rice hulling quality.

[0033] like Figures 1 to 3As shown, the sampling mechanism 3 includes a square and round pipe 31 provided at the discharge port of the rice huller body 1, a feed gate 32 rotatably connected to the connection between the square and round pipe 31 and the discharge port of the rice huller body 1, a swing arm 33 provided at one end of the rotating shaft of the feed gate 32, and a driving cylinder 34 hingedly provided between the outer side of the discharge port of the rice huller body 1 and the swing arm 33. When the driving cylinder 34 drives the feed gate 32 to rotate, the feed gate 32 and the top of the square and round pipe 31 form an opening for the rice grain sample to enter, and the negative pressure suction mechanism is connected to the square and round pipe 31.

[0034] like Figures 1 to 3 As shown, the negative pressure suction mechanism includes a feed bin 51 arranged on the feed pipe 41 of the hulled rice quality analyzer 4, a suction pipe 52 connected between the feed bin 51 and the square and round connecting pipe 31, a suction machine 53, and an air outlet pipe 54 connected between the suction machine 53 and the top of the feed bin 51. A filter element (not shown in the figure) is provided on the top of the feed bin 51 to prevent the rough rice sample from entering the air outlet pipe 54.

[0035] like Figures 1 to 3 As shown, the discharge pipe 42 of the hulled rice quality analyzer 4 is detachably provided with a buffer bin 6 for storing rough rice samples.

[0036] Implementation effect: A certain amount of rice rough samples are taken regularly or at any time through the sampling mechanism 3, and the rice rough samples are drawn into the online rice hulling quality analyzer 4 through the negative pressure suction mechanism. The hulling rate, rice roughness rate and rice husk content of the rice rough samples are obtained through the rice hulling quality analyzer 4, and the online detection results are fed back to the control box 2 of the rice huller body 1, so as to adjust and optimize the rice hulling process parameters and improve the rice hulling quality.

[0037] When the sampling mechanism 3 is in use, the piston rod of the driving cylinder 34 is extended and retracted to drive the swing arm 33 to rotate, and the swing arm 33 drives the rotating shaft of the feed door 32 to rotate, so that the feed door 32 and the top of the square tube are formed to allow the rough sample to enter. After a certain amount of rough grain sample enters, the driving cylinder 34 is reset to close the feed door 32, and then the rough grain sample in the square tube 31 is input into the rice hulling quality analyzer 4 through the negative pressure suction mechanism. The negative pressure suction mechanism includes a feed bin 51 arranged on the feed pipe 41 of the rice hulling quality analyzer 4, a suction pipe 52 connected between the feed bin 51 and the square and circular connecting pipe 31, a suction machine 53, and an air outlet pipe 54 connected between the suction machine 53 and the top of the feed bin 51. The top of the feed bin 51 is provided with a filter element for preventing the rough grain sample from entering the air outlet pipe 54. When the suction machine 53 is working, the rough grain sample in the square and circular connecting pipe 31 can be extracted into the feed bin 51, and when filtered by the filter element, it falls into the feed pipe 41 of the rice hulling quality analyzer 4. Then, after the valve at the feed pipe 41 of the rice hulling quality analyzer 4 is opened, the rough grain sample is allowed to enter for online detection.

[0038] Example 2: A smart rice huller that realizes flexible processing, such as Figure 4 and Figure 5 As shown, the difference from Example 1 lies in the structure of the sampling mechanism 3. The feeding port of the rice huller body 1 is provided with a square shell 11, and a square sampling port 111 is provided on the side of the square shell 11. The sampling mechanism 3 includes a connecting shell 35 provided on the square shell 11 and communicating with the square sampling port 111, a sampling box 36 telescopically provided in the connecting shell 35 and with an open end away from the square shell 11, a power assembly 37 provided between the connecting shell 35 and the sampling box 36 and driving the sampling box 36 to move, and a sealing assembly 38 provided at the open end of the sampling box 36 to open or close the open end. A feeding port 361 is provided at the top of the sampling box 36 near the end of the square shell 11. When the sampling box 36 moves toward the direction close to the square shell 11 to a set limit state, the sealing assembly 38 closes the open end. When the sampling box 36 moves toward the direction away from the square shell 11 to a set limit state, the sealing assembly 38 opens the open end. The connecting shell 35 is connected to the suction pipe 52.

[0039] like Figures 5 to 7 As shown, a notch 351 is provided at the top of the connecting shell 35, and a tooth groove 362 with a length greater than the notch 351 is provided at the bottom of the sampling box 36 corresponding to the notch 351. The power assembly 37 includes a bracket 371 arranged at the bottom of the square shell 11, a gear 372 rotatably connected to the bracket 371 and meshing with the tooth groove 362 after passing through the notch 351, and a motor 373 arranged on the bracket 371 and linked to the gear 372 through a belt drive.

[0040] like Figure 5 and Figure 6 As shown, the sealing assembly 38 includes a cover plate 381 hingedly arranged on the top of the connecting shell 35 and a sealing plug 382 arranged on the cover plate 381; when the sampling box 36 moves toward the direction close to the square shell 11 to the set extreme state, the cover plate 381 is first maintained in a horizontal state under the limiting action of the sampling box 36, and then is in a vertical state under the action of gravity so that the sealing plug 382 on the cover plate 381 is embedded in the open end of the sampling box 36. When the sampling box 36 moves toward the direction away from the square shell 11 to the set extreme state, the sampling box 36 first drives the cover plate 381 to rotate upward to a horizontal state, and then keeps the cover plate 381 in a horizontal state.

[0041] like Figures 6 to 7As shown, a connecting pipe port 352 corresponding to the cover plate 381 is provided on the top of the connecting shell, and a filter 71 is connected to the connecting pipe port 352. A dust collecting hood 72 extending downward and lower than the square shell 11 is provided on the peripheral side of the square shell 11. A dust suction pipe 73 with multiple dust suction ports is provided at the angle between the dust collecting hood 72 and the peripheral side of the square shell 11, and a negative pressure pipe 74 is provided between the dust suction pipe 73 and the filter 71; a counterweight block 3811 is provided at the corresponding connecting pipe port 352 of the cover plate 381, which is in the connecting pipe port 352 when in a horizontal state, and the counterweight block 3811 is in the lower half when the cover plate 38 is rotated to a vertical state; an annular sealing ring 3812 is provided on the cover plate 381, which is pressed against the top of the connecting shell 35 when maintained in a horizontal state and covers the connecting pipe port 352. When the sampling box 36 moves toward the square housing 11 and the feed port 361 is not positioned within the square housing 11, the cover 381 rotates downward to open the connecting pipe 352. Furthermore, a protective mesh 75 is provided at the angle between the dust hood 72 and the side of the square housing 11 to prevent grain grains from being sucked in.

[0042] Implementation effect: During the movement of the sampling box 36 driven by the power component 37, when the sampling box 36 moves toward the direction close to the square shell 11 to the set extreme state, the rough grain sample enters from the feed port 361 of the sampling box 36, and the sealing component 38 closes the open end to achieve quantitative sampling; and when the sampling box 36 moves toward the direction away from the square shell 11 to the set extreme state, the sealing component 38 opens the open end, so that the rough grain sample is extracted by the negative pressure suction mechanism.

[0043] During operation of the power assembly 37, the motor 373 drives the gear 372 to rotate, and the gear 372 engages with the tooth groove 362 of the sampling box 36, thereby driving the sampling box 36 to move. The sealing assembly 38 includes a cover plate 381 and a sealing plug 382. When the sampling box 36 moves toward the direction close to the square shell 11 to a set limit state, the cover plate 381 is first maintained in a horizontal state under the limit of the sampling box 36, and then in a vertical state under the action of gravity so that the sealing plug 382 on the cover plate 381 is embedded in the open end of the sampling box 36. When the sampling box 36 moves toward the direction away from the square shell 11 to a set limit state, the sampling box 36 first drives the cover plate 381 to rotate upward to a horizontal state, and then keeps the cover plate 381 in a horizontal state.

[0044] There is always rice roughness output at the unloading point of the rice huller body 1, and some dust will be raised when unloading at the unloading point of the rice huller body 1. When the sampling box 36 moves toward the direction close to the square shell 11 and the feed port 361 is not located in the square shell 11, the cover 381 is rotated downward to open the connecting pipe 352. At this time, when the suction machine 53 is working, the air flows along the dust suction pipe 73, the negative pressure pipe 74, and the filter 71 to achieve dust suction and avoid dust. At the same time, due to the setting of the counterweight 3811 on the cover 381, the cover 381 is not easy to shake during this process, and the setting of the counterweight 3811 on the cover 381 is better when the open end of the sampling box 36 is sealed. The setting of the connecting pipe 352 provides space for storing the counterweight 3811 on the cover 381.

[0045] This specific embodiment is merely an explanation of the present invention and is not intended to limit the present invention. After reading this specification, those skilled in the art may make non-creative modifications to this embodiment as needed. However, as long as such modifications are within the scope of the claims of the present invention, they are protected by patent law.
