Description

Technical Field

[0001] This application relates to the field of rice production technology, and in particular to a high-efficiency rice polishing and color sorting device. Background Technology

[0002] Rice has high nutritional value and is a staple food for the Chinese people. Therefore, there are strict requirements for rice production.

[0003] In related technologies, a rice production process is designed. First, the rice is milled to remove the outer husk and then poured into a polishing machine for polishing. After polishing, the rice is fed into a color sorter for color sorting, thereby screening out rice with problems in appearance and color. This rice is then fed into another polishing machine for polishing, and after the second polishing is completed, it is fed into the color sorter for a second color sorting, thus obtaining high-quality rice.

[0004] Regarding the aforementioned technologies, the inventors have found that existing rice production lines are quite long. In order to achieve batch and continuous production of rice, two polishing machines are generally used to complete the primary and secondary polishing operations respectively. Similarly, multiple color sorters are also generally used, resulting in large space occupation, high economic costs, and the need for manual labor to pour rice into the polishing or color sorting machines, leading to low work efficiency. Therefore, improvements are needed. Summary of the Invention

[0005] In order to save the cost of equipment required for rice production, reduce the size and footprint of rice production lines, and improve the efficiency of rice production, this application provides a high-efficiency rice polishing and color sorting device.

[0006] The high-efficiency rice polishing and color sorting device provided in this application adopts the following technical solution:

[0007] A high-efficiency rice polishing and color sorting device includes a worktable with interconnected polishing chamber, color sorting chamber, and output port. An inlet is located on the surface of the worktable and is connected to the polishing chamber. A polishing assembly is installed within the polishing chamber to transport rice from the polishing chamber to the color sorting chamber and polish the rice during transport. A color sorting assembly is installed within the color sorting chamber to screen the rice and transport the screened rice to the output port. An elevator is installed on the worktable, with one end connected to the color sorting chamber and the other end connected to the inlet. The elevator is used to re-feed the rice screened out by the color sorting assembly into the polishing chamber.

[0008] It also includes a timer and a control module. The timer is used to calculate the number of times the elevator runs, and the control module is used to stop conveying rice from the elevator to the polishing chamber when the number of runs exceeds a specified number.

[0009] By adopting the above technical solution, rice is fed into the polishing chamber through the inlet, polished by the polishing components, and then transported into the color sorting chamber. After being sieved by the color sorting components, rice with unqualified color is removed, while qualified rice passes through the color sorting components and finally enters the output port to be discharged from the worktable. The sieved inferior rice slides along the conveyor surface and moves to the elevator, which then transports it back into the inlet for secondary polishing, allowing for a new round of color sorting. This process is repeated, effectively improving rice production efficiency and addressing the issue of insufficient polishing leading to unqualified rice. The present application addresses the issue of high rice waste rates. It integrates the polishing and color sorting processes in rice production, achieving a high degree of integration, saving space and manpower, and effectively improving rice production efficiency, resulting in significant economic benefits. Furthermore, the timer counts the number of elevator runs and compares them to a preset value. If the elevator runs reach the preset value, it determines that the remaining rice is of low quality and stops transporting the rice from the elevator to the polishing chamber, thus terminating the polishing and color sorting process for that batch of rice. This high degree of automation saves energy and effectively improves the overall efficiency of the rice production process.

[0010] Preferably, the color sorting assembly includes a partition plate, a flow pipe, a baffle, a material lamp, a material camera, and an air compressor; the partition plate and the baffle are both connected to the inner wall of the color sorting chamber; the flow pipe passes through the partition plate and the baffle in sequence; one end of the flow pipe passing through the baffle is connected to the output port; the surface of the baffle has a material conveying surface, which is inclined towards the direction of the elevator; the flow pipe has a color sorting port through it along the thickness direction, which is located between the partition plate and the baffle; the material lamp, the material camera, and the air compressor are all connected to the inner wall of the color sorting chamber, and the material lamp, the material camera, and the air compressor are all arranged towards the color sorting port.

[0011] The material light, material camera, and air compressor are all electrically connected to the control module. The control module includes a color difference comparison unit for receiving images captured by the material camera and comparing them with a standard color difference, and controlling the start and stop of the air compressor based on the comparison result.

[0012] By adopting the above technical solution, when rice enters the color sorting chamber through the discharge port, it will fall onto the surface of the separator plate. The rice will then enter the flow pipe and fall along it. When the rice passes through the color sorting port, the material lamp will illuminate it, and the material camera will take a picture of it. The material camera will transmit the captured image to the control module. The color difference comparison module in the control module will analyze whether the color of the rice is qualified. If the color of the rice is unqualified, the control module will control the air compressor to start, blowing the inferior rice into the color sorting port and onto the conveyor surface, moving it towards the elevator for subsequent secondary polishing. If the color of the rice is qualified, it will move along the flow pipe and pass through the baffle into the output port. The color sorting component of this application can efficiently screen rice, has a simple structure, high mobility, and can effectively improve the rice production efficiency, with high practicality and convenience.

[0013] Preferably, the inner wall of the connection between the polishing chamber and the color sorting chamber is provided with a lighting lamp and a camera. The lighting lamp and the camera are both electrically connected to the control module. The control module also includes a rice type analysis unit and a material lighting adjustment unit.

[0014] The rice variety analysis unit is used to analyze the rice variety based on the image transmitted by the camera and transmit the signal to the color difference comparison unit to select the color difference contrast of the corresponding rice variety.

[0015] The material lighting adjustment unit is used to adjust the lighting of the material lamp based on the results of the rice type analysis unit.

[0016] By adopting the above technical solution, the lighting and camera can take pictures of the rice coming out of the discharge port and transmit the images to the rice variety analysis unit of the control module. This allows the color difference comparison unit to select the standard color of the corresponding type of rice for color sorting during subsequent color sorting, reducing the probability of incorrect color sorting due to errors in the standard color selected by the color difference comparison unit. Furthermore, the intensity of the light can be adjusted by the material lighting adjustment unit to improve the accuracy of color sorting, resulting in high economic benefits and practicality.

[0017] Preferably, a guide plate is rotatably connected to the inner wall of the feed inlet, and a rotating component is provided on the worktable for driving the guide plate to rotate. The rotating component is controlled by a control module. A waste frame is provided on the surface of the worktable. After the guide plate rotates, it can be used to separate the elevator from the feed inlet and allow the rice to enter the waste frame.

[0018] By adopting the above technical solution, the rotating component is activated to drive the guide plate to rotate in the direction of the elevator, thereby isolating the elevator from the feed inlet. When inferior rice still cannot pass the color sorting after multiple rounds of polishing and grinding, the rotating component can be activated, so that the rice conveyed by the elevator will enter the waste box through the guide plate, which has high practicality and convenience.

[0019] Preferably, a vibrating plate is provided on the side of the partition plate away from the color sorting cavity, a plurality of reset springs are provided on the bottom wall of the vibrating plate, a plurality of reset holes are provided on the surface of the partition plate for the reset springs to be embedded, one end of the flow pipe passes through the vibrating plate, and a plurality of vibrating elements for driving the movement of the vibrating plate are provided on the surface of the vibrating plate.

[0020] By adopting the above technical solution, the vibration plate and vibration components can vibrate the rice falling on the surface of the vibration plate, so that the rice can enter the flow pipe, which improves the problem of excessive accumulation of rice on the surface of the barrier plate, which causes the color sorting component to become clogged. At the same time, it can effectively improve the working efficiency of the device and the rice production efficiency of this application.

[0021] Preferably, the vibrating component includes a vibrating motor, a vibrating column, and abutting column. The surface of the partition plate has an installation port for installing the vibrating motor. The vibrating column is connected to the output shaft of the vibrating motor. The side wall of the vibrating column has a vibrating surface. The vibrating surface is opened around the vibrating column and is opened from the end of the vibrating column near the vibrating motor to the end away from the vibrating motor. The abutting column is connected to the bottom wall of the vibrating plate and abuts against the vibrating surface.

[0022] By adopting the above technical solution, the vibration motor is started, and the output shaft of the vibration motor will drive the vibration column to rotate. During the rotation of the vibration column, the contact point between the contact column and the vibration surface will change with the rotation of the vibration column. As the contact column rises, the vibration plate rises, thereby achieving the effect of continuous vibration of the vibration plate. This effectively improves the problem that rice cannot enter the flow tube after entering the color sorting chamber, which leads to blockage of the color sorting component. This effectively improves the rice production rate of the device of this application.

[0023] Preferably, the inner wall of the color sorting chamber is connected to a guide block, the guide block is located on the side of the vibrating plate away from the partition plate, the surface of the guide block is provided with a dispersion surface, the dispersion surface is inclined in the direction away from the feed inlet, and the guide block is provided with a plurality of feed holes through it along the thickness direction.

[0024] By adopting the above technical solution, setting a guide block and opening a dispersion surface on the surface of the guide block, the rice entering the color sorting chamber can be effectively dispersed, which improves the problem of rice being too concentrated and some flow tubes not being able to perform their normal function. This helps to improve the color sorting speed of rice by the color sorting component of this application, and has high practicality and convenience.

[0025] Preferably, the bottom wall of the guide block is provided with a flow limiting plate, the surface of the flow limiting plate is divided into several flow limiting zones, each flow limiting zone corresponds to a feeding hole, and each flow limiting zone is provided with several flow limiting holes of different sizes through it along the thickness direction; the inner side wall of the color sorting chamber is provided with a sliding groove for the flow limiting plate to be embedded and slide, a sliding cylinder is provided in the sliding groove, the sliding cylinder is electrically connected to the control module, and the piston rod of the sliding cylinder is connected to the side wall of the flow limiting plate.

[0026] By adopting the above technical solution, setting a flow-limiting plate and opening flow-limiting holes of different sizes on the surface of the flow-limiting plate, the flow rate of rice can be effectively controlled, reducing the problem of excessive rice accumulation on the surface of the vibrating plate, which would cause the vibrating plate to malfunction, and reducing the probability of clogging of the color sorting component. It has high practicality and safety.

[0027] Preferably, a gravity sensor is provided on the bottom wall of the vibrating plate, and the gravity sensor is electrically connected to the control module. The control module further includes a weight difference calculation unit, a difference comparison unit, and an execution unit.

[0028] The weight difference calculation unit is used to calculate the difference between the data transmitted by the gravity sensor and the preset weight;

[0029] The difference comparison unit is used to receive the data transmitted by the weight difference calculation unit and compare it with the corresponding difference interval;

[0030] The execution unit is used to receive the value output by the difference comparison unit, and control the sliding cylinder to select a flow-limiting orifice of appropriate size based on the value.

[0031] By adopting the above technical solution, a gravity sensor can sense the weight of rice on the surface of the vibrating plate and transmit the measured weight to the control module. The weight difference calculation unit calculates the difference with a preset value and transmits the result to the difference comparison unit to determine whether the amount of rice on the vibrating plate is within the weight range for normal color sorting. The difference comparison unit transmits the value to the execution unit to control the formation of the sliding cylinder, thereby enabling more precise control of the rice color sorting speed. This reduces the probability of insufficient rice, low color sorting efficiency, or excessive rice causing blockage of the color sorting component.

[0032] Preferably, the polishing assembly includes a feed roller and a drive component. The feed roller is rotatably connected to the inner wall of the polishing chamber, and a spiral blade is connected to the peripheral wall of the feed roller. The drive component is connected to the side wall of the worktable and is controlled by a control module. The drive component is connected to the feed roller and can drive the feed roller to rotate. The inner wall of the polishing chamber is provided with a first polishing protrusion, and the outer wall of the feed roller is provided with a second polishing protrusion.

[0033] The execution unit can also control the power of the drive component based on the value output by the difference comparison unit to adjust the rotation speed of the feed roller.

[0034] By adopting the above technical solution, the spiral blades on the outer wall of the conveying roller convey the rice in a spiral manner. During the conveying process, the rice will be repeatedly rubbed between the first polishing protrusion and the second polishing protrusion, thereby polishing the defects on the surface of the rice and improving the appearance of the rice. The execution unit can control the rotation speed of the conveying roller, thereby effectively reducing the probability of the color sorting component being blocked due to the rice being output too fast.

[0035] In summary, this application includes at least one of the following beneficial technical effects:

[0036] 1. By opening a polishing chamber and a color sorting chamber, and setting up a feeding roller, a color sorting component and an elevator, this application enables the polishing and color sorting processes in rice production to be more centralized, improves the integration of rice production, saves the space occupied by setting up multiple machines, and effectively improves the efficiency of rice production;

[0037] 2. By setting up a vibrating plate and vibrating components, the rice entering the color sorting chamber can be vibrated, thereby allowing the rice to enter the flow tube. This reduces the probability of excessive rice accumulation in the color sorting chamber, which prevents it from entering and causes blockage. It has high practicality.

[0038] 3. By setting up a control module, it can perform color sorting of rice, analyze the types of rice, determine the weight of rice in the color sorting chamber, and control the flow rate of rice. It has complete functions and effectively improves the production efficiency of rice. Attached Figure Description

[0048] The following is in conjunction with the appendix Figure 1-8 This application will be described in further detail.

[0049] This application discloses a high-efficiency rice polishing and color sorting device. (Refer to...) Figure 1 and Figure 2A high-efficiency rice polishing and color sorting device includes a workbench 1, with a feed inlet 14 on the top wall of the workbench 1 and a polishing chamber 11 inside the workbench 1. The polishing chamber 11 communicates with the feed inlet 14, allowing the operator to feed rice into the workbench 1 through the feed inlet 14. A guide plate 141 is rotatably connected to the feed inlet 14, and a rotating component 142 is provided on the surface of the workbench 1 for driving the guide plate 141 to rotate. In this embodiment, the rotating component 142 is a pulley. By setting the pulley to control the rotation of the guide plate 141, the opening and closing state of the feed inlet 14 can be effectively controlled, thereby providing good protection for the inside of the workbench 1.

[0050] Reference Figure 2 The polishing chamber 11 is equipped with a polishing assembly 2 for transporting and polishing rice. The polishing assembly 2 includes a feeding roller 21 and a driving component 22. The feeding roller 21 is rotatably connected to the inner wall of the polishing chamber 11, and the driving component 22 is welded to the outer wall of the worktable 1. The driving component 22 is connected to the feeding roller 21 and can drive the feeding roller 21 to rotate. In this embodiment, the driving component 22 is a motor, and the output shaft of the driving component 22 passes through the outer wall of the worktable 1 and is connected to the feeding roller 21 to drive the feeding roller 21 to rotate. The peripheral wall of the feeding roller 21 is integrally formed. The device has a spiral blade 211, which is arranged along the length of the conveying roller 21. By setting the spiral blade 211, the rice in the polishing chamber 11 can be transported in a spiral conveying manner. The inner wall of the polishing chamber 11 is integrally formed with a number of first polishing protrusions 113, and the peripheral wall of the conveying roller 21 is integrally formed with a number of second polishing protrusions 212. When the rice is conveyed, the surface of the rice can be polished by the first polishing protrusions 113 and the second polishing protrusions 212, thereby effectively improving the appearance and color of the rice.

[0051] Reference Figure 2 The workbench 1 has a color sorting chamber 12 located below the polishing chamber 11. The color sorting chamber 12 and the polishing chamber 11 are connected at the end away from the feed inlet 14. The inner wall of the connection between the polishing chamber 11 and the color sorting chamber 12 is welded together with a lighting lamp 111 and a camera 112 to capture images of the rice passing through the connection. The inner wall of the color sorting chamber 12 near the connection with the polishing chamber 11 is welded together with a guide block 7. The surface of the guide block 7 has a dispersing surface 71. The dispersing surface 71 is inclined from the end of the guide block 7 near the discharge port toward the end away from the discharge port. The guide block 7 has a plurality of feeding holes 72 through it along the thickness direction. The plurality of feeding holes 72 are evenly distributed along the length direction of the guide block 7, so that the rice can be evenly fed into the color sorting chamber 12 through the inclined dispersing surface 71 and the plurality of feeding holes 72.

[0052] Reference Figure 2 and Figure 3The color sorting chamber 12 has sliding grooves 121 on both sides of its inner wall in the width direction. A flow limiting plate 8 is slidably connected between the two sliding grooves 121. The flow limiting plate 8 includes several interlocking flow limiting areas 81. Each flow limiting area 81 has several flow limiting holes 82 of different sizes through it along the thickness direction. In this embodiment, each feeding hole 72 corresponds to a flow limiting area 81. A sliding cylinder 9 is welded to the sliding groove 121. The piston rod of the sliding cylinder 9 is welded to the side wall of the flow limiting plate 8, so that the flow limiting plate 8 can slide back and forth between the two sliding grooves 121 to select flow limiting holes 82 of different sizes. This can effectively control the flow rate of rice entering the color sorting chamber 12, reduce the probability of blockage in the color sorting chamber 12, and improve the efficiency of rice production.

[0053] Reference Figure 2 and Figure 4 The color sorting chamber 12 is equipped with a color sorting component 3 for sorting rice. The color sorting component 3 includes a separator 31, several flow pipes 32, a baffle 33, several material lights 34, several material cameras 35, and several air compressors 36. The separator 31 and the baffle 33 are welded to the inner wall of the color sorting chamber 12. The separator 31 is located on the side of the flow limiting plate 8 away from the guide block 7, and the baffle 33 is located on the side of the separator 31 away from the flow limiting plate 8. Several flow pipes 32 pass through the separator 31 and the baffle 33 in sequence. The space below the baffle 33 forms an output port 13 for outputting color-sorted rice.

[0054] Reference Figure 4 The flow tubes 32 are inclined, and each flow tube 32 located between the partition plate 31 and the baffle plate 33 has a color sorting port 321. The material lamp 34 and the material camera 35 are welded to the inner wall of the color sorting chamber 12 and are both facing the color sorting port 321. They can illuminate and photograph the material from both sides of the flow tubes 32. The air compressor 36 is welded to the inner wall of the color sorting chamber 12. The air outlet of the air compressor 36 is facing the color sorting port 321, so that the inferior rice passing through the color sorting port 321 can be blown out by emitting compressed air to achieve the color sorting effect.

[0055] Reference Figure 2 and Figure 4 The surface of the baffle 33 is inclined along the length direction and has a conveying surface 331. The workbench 1 is equipped with a hoist 15. The blown-out inferior rice can roll along the conveying surface 331 and be transported to the hoist 15. The other end of the hoist 15 is set towards the feed inlet 14, so that the inferior rice can be transported into the feed inlet 14 for secondary polishing and color sorting, thereby improving the rice yield and saving the cost of setting up additional equipment for secondary polishing and color sorting of inferior rice. It has a high degree of integration and good economic benefits.

[0056] Reference Figure 1 The workbench 1 has a waste box 16 on its surface. When the guide plate 141 rotates toward the elevator 15, rice that is still not qualified after multiple rounds of screening can enter the waste box 16 through the guide plate 141 and will no longer be polished and sorted.

[0057] Reference Figure 2 and Figure 5 A vibrating plate 6 is provided on the side of the separator 31 near the flow limiting plate 8. One end of the flow tube 32 passes through the separator 31. Several return springs 61 are glued to the bottom wall of the vibrating plate 6. Several return holes 311 are provided on the surface of the separator 31 for the return springs 61 to be embedded. The other end of the return spring 61 is glued to the bottom wall of the return hole 311. Several vibrating elements 63 are provided on the vibrating plate 6 so that the vibrating plate 6 can vibrate. This can effectively improve the problem that rice falling on the surface of the separator 31 is difficult to enter the flow tube 32, improve the color sorting efficiency of rice, and effectively improve the problem of blockage in the color sorting chamber 12.

[0058] Reference Figure 5 and Figure 6 The vibrating component 63 includes a vibrating motor 631, a vibrating column 632, and an abutment column 634. The partition plate 31 has a mounting opening 312 for mounting the vibrating motor 631. The base of the vibrating motor 631 is welded into the mounting opening 312, and the output shaft of the vibrating motor 631 faces the vibrating plate 6. The vibrating column 632 is welded to the end wall of the output shaft of the vibrating motor 631. The side wall of the vibrating column 632 has a vibrating surface 6321, which is spirally formed. The vibrating column 632 of the vibrating plate 6321 is located on the side of the vibrating motor 631 that faces away from the vibrating motor 631. The abutment column 634 is welded to the bottom wall of the vibrating plate 6. The abutment column 634 can abut against the vibrating surface 6321 at any time. As the vibrating column 632 rotates, the abutment column 634 is gradually lifted and then falls rapidly after the vibrating column 632 rotates. This achieves repeated vibration of the vibrating plate 6 to achieve the effect of sieving rice. The structure is simple and easy to implement.

[0059] Reference Figure 1 and Figure 2 The high-efficiency rice polishing color sorting device of this application also includes a timer 4 and a control module 5. The timer 4 is electrically connected to the control module 5. The color sorting component 3, the rotating component 142, the driving component 22, the lighting lamp 111 and the camera 112 are all controlled by the control module 5. The control module 5 is equipped with a PLC controller.

[0060] Reference Figure 2 , Figure 7 and Figure 8The control module 5 includes a rice type analysis unit 52, which receives images captured by the camera 112 and analyzes the type of rice to be processed; the control module 5 also includes a material lighting adjustment unit 53, which receives signals from the rice type analysis unit 52 and automatically adjusts the material light 34 to a light suitable for displaying the color of the corresponding rice type; the control module 5 also includes a color difference comparison unit 51, which receives signals from the rice type analysis unit 52 and selects a suitable preset standard color, and can also receive images captured by the material camera 35 and compare them with the standard color difference to analyze whether the quality of the rice is qualified, and use it to control the start and stop of the air compressor 36 to realize the color sorting process of rice.

[0061] Reference Figure 2 , Figure 7 and Figure 8 A gravity sensor 62 is glued to the bottom wall of the vibrating plate 6 to detect the weight of rice on the vibrating plate 6. The gravity sensor 62 is electrically connected to the control module 5. The control module 5 also includes a weight difference calculation unit 56 to receive the output signal of the gravity sensor 62 and calculate the difference with a preset value. The control module 5 also includes a difference comparison unit 57 to receive the signal transmitted from the weight difference calculation unit 56, find the corresponding difference range, and transmit the result. The control module 5 also includes an execution unit 58 to receive the result of the difference comparison unit 57 and control the sliding cylinder 9 to start based on the result. This allows for the selection of a suitable size flow-limiting orifice 82 to improve the problem of too much or too little rice on the vibrating plate 6, which affects the rice production efficiency. At the same time, the execution unit 58 can also control the power of the drive component 22 based on the numerical value to adjust the rotation speed of the conveying roller 21, thereby further adjusting the output rate of rice.

[0062] Reference Figure 1 , Figure 7 and Figure 8 The control module 5 also includes a counting unit 54 for receiving the value of the timer 4 and recording the number of times the elevator 15 is activated; the control module 5 also includes a value comparison unit 55 for receiving the signal from the counting unit 54 and transmitting the signal when the value is equal to the preset value. The execution unit 58 can also receive the value from the value comparison unit 55 and control the rotating part 142 to make the guide plate 141 rotate toward the elevator 15, thereby collecting the rice that is still unqualified after multiple rounds of polishing and color sorting.

[0063] The implementation principle of the high-efficiency rice polishing and color sorting device in this application embodiment is as follows: rice is fed into the polishing chamber 11 through the feed inlet 14, and the drive component 22 is started to drive the conveying roller 21 to rotate, thereby conveying the rice in a spiral. During the conveying process, the rice comes into contact with the first polishing protrusion 113 and the second polishing protrusion 212, thereby polishing the surface of the rice.

[0064] The polished rice enters the color sorting chamber 12 and eventually falls onto the surface of the vibrating plate 6. The vibrating plate 6 is driven to vibrate by the vibrating element 63, ensuring that the rice can only smoothly enter the flow pipe 32. When the rice passes through the color sorting port 321, the material camera 35 takes a picture of the rice and transmits the image to the control module 5. The image is then compared with the surface color of normal rice. If the analysis shows that the color of the rice is unqualified, the air compressor 36 will blow air to blow out the inferior rice, which will then enter the elevator 15 along the conveying surface 331. The elevator 15 will then transport the rice into the polishing chamber 11 for secondary polishing. The rice with qualified color will continue to move and enter the output port 13. By repeating the above steps, the rice yield can be effectively improved after multiple polishing processes.

[0065] This application discloses a high-efficiency rice polishing and color sorting device that combines the polishing and color sorting processes of rice, resulting in a higher degree of integration in the rice production process. This saves space that would otherwise require multiple machines in rice production, effectively improves the efficiency of rice production, and has high economic benefits.

[0066] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
