Description

Technical Field

[0001] This utility model relates to the technical field of grain processing equipment, specifically a dual-channel sorting device for a rice color sorter. Background Technology

[0002] In the grain processing industry, rice color sorting is a crucial step in ensuring rice quality. Its main function is to remove discolored particles, impurities, and imperfect grains from the rice, thereby improving its commercial value and food safety. Currently, most rice color sorters on the market adopt a single-channel sorting structure. This structure has a limited rice processing capacity per unit time, making it difficult to meet the high-efficiency requirements of large-scale grain processing production lines.

[0003] The prior art includes a feeding device for a rice color sorter, as disclosed in patent application number CN202222303731.6. This device includes a rice color sorter body, a feeding hopper on top of the body, a base plate on the right side of the body, a support rod fixedly connected to the top of the base plate, a vacuum cleaner on the top of the base plate, a conveying pipe fixedly connected to the top of the support rod, and a feed hopper penetrating the right side of the conveying pipe. A sealing cover is hinged to the top of the feed hopper, a right suction pipe connects the sealing cover to the vacuum cleaner, a left suction pipe connects the vacuum cleaner to the feeding hopper, and a feed pipe penetrating the lower left side of the conveying pipe. The feed pipe is inserted into the upper right side of the inside of the feeding hopper. This utility model proposes a feeding device for a rice color sorter, which facilitates better automatic quantitative feeding and can automatically remove dust from the positions of the feeding hopper and the feeding hopper. However, this technical solution often results in uneven feeding due to rice accumulation and clumping, affecting the subsequent color sorting accuracy. During the process of conveying rice to the sorting channel, rice is prone to scattering and uneven distribution, which not only wastes grain but also reduces color sorting efficiency. In addition, the detection components of traditional color sorters are mostly fixed, which cannot fully cover the rice in the sorting channel and is prone to missed detection, resulting in discolored particles being mixed into the finished rice and affecting the quality of the rice.

[0004] In view of this, we propose a dual-channel sorting device for rice color sorting machines. Utility Model Content

[0005] To overcome the above deficiencies, this utility model provides a dual-channel sorting device for rice color sorting machines.

[0006] The technical solution of this utility model is:

[0007] The dual-channel sorting device for rice color sorting includes a base plate, a storage bin on top of the base plate, and a guide rail assembly installed on the top of the base plate below the storage bin. The guide rail assembly includes a main guide rail and two branch guide rails integrally formed on the right side of the main guide rail. A paddle motor is installed at the center of the guide rail assembly, and a paddle plate is coaxially fixed to the output shaft of the paddle motor. A horizontal plate is fixedly connected to the outer wall of the storage bin, and a movable block is slidably installed at the bottom of the horizontal plate. An observation lens is fixed at the bottom of the movable block, and the observation lens is directly opposite the guide rail assembly. A support leg is fixedly installed at each of the four corners of the bottom of the base plate. By setting up a base plate, a storage bin, and a guide rail assembly including a main guide rail and two branch guide rails, along with a paddle motor and paddle plate, the rice is diverted. At the same time, a sliding observation lens is used to accurately observe the rice on the guide rail assembly. The overall structure allows the rice to enter the dual channels for sorting in an orderly manner, greatly increasing the rice processing capacity per unit time. The sliding design of the observation lens ensures comprehensive monitoring of the rice in both channels, providing a foundation for subsequent accurate sorting and effectively improving the working efficiency and reliability of the color sorter.

[0008] As a preferred technical solution, two collecting plates are symmetrically fixedly connected to one end of the main guide rail near the branching guide rail, and the width between the two collecting plates gradually decreases to the right. This effectively guides and gathers the rice about to enter the branching guide rail, preventing the rice from scattering or shifting at the branching point, and ensuring that the rice enters the two branching guide rails accurately and evenly.

[0009] As a preferred technical solution, a conveyor belt is installed inside both the main guide rail and the branch guide rail. A pad is provided at the bottom of the branch guide rail, and the pad is fixed to the top of the base plate. This ensures that the rice can be transported smoothly and continuously throughout the guide rail assembly, avoiding jamming or accumulation during the rice transport process.

[0010] As a preferred technical solution, the bottom of the storage bin is equipped with a feeding pipe facing the main guide rail, and a feeding valve is installed on the feeding pipe. This ensures that the rice in the storage bin falls accurately into the main guide rail, avoiding deviation during rice feeding; the feeding valve installed on the feeding pipe can flexibly control the feeding speed and amount of rice.

[0011] As a preferred technical solution, a support column is fixedly installed at each of the four corners of the bottom of the storage bin. These support columns are fixedly installed on the top of the base plate, providing stable support for the storage bin and enhancing its overall structural strength. The top of the storage bin has a feeding port, and a lid is installed on top of the feeding port. A handle is fixedly installed on top of the lid. The feeding port and the lid with a handle on the top of the storage bin facilitate the addition of rice to the bin by workers, and the lid effectively prevents external dust and impurities from entering the storage bin and contaminating the rice, ensuring the cleanliness of the rice to be sorted.

[0012] As a preferred technical solution, a stirring shaft is rotatably installed inside the storage bin, and several stirring blades are fixedly installed on the outer circumference of the stirring shaft. A stirring motor with an output shaft coaxially fixed to the stirring shaft is fixedly installed on the top of the storage bin. This can fully stir the rice in the storage bin, prevent the rice from clumping due to long-term storage, and ensure that the rice remains loose and is evenly discharged from the discharge pipe when it is fed.

[0013] As a preferred technical solution, the horizontal plate has a movable groove inside for the movable block to move. A lead screw is rotatably installed in the movable groove and is threadedly connected to the movable block. A drive motor, coaxially fixed with the lead screw, is installed at the right end of the horizontal plate. Driven by the drive motor, the movable block can move the observation lens precisely horizontally, allowing the observation lens to observe different positions of the guide rail assembly in detail.

[0014] As a preferred technical solution, a diagonal brace is fixed to the top of the horizontal plate, and the other end of the diagonal brace is fixedly connected to the outer wall of the storage box. This enhances the structural stability of the horizontal plate when supporting components such as observation lenses.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] This invention utilizes a base plate, a storage bin, and a guide rail assembly comprising a main guide rail and two branch guide rails. Combined with a paddle motor and paddle plate, it achieves rice diversion. Simultaneously, a sliding observation lens allows for precise observation of the rice on the guide rail assembly. The overall structure enables the rice to enter the dual channels for sorting in an orderly manner, significantly increasing the rice processing capacity per unit time. Furthermore, the sliding design of the observation lens ensures comprehensive monitoring of the rice in both channels, providing a foundation for subsequent precise sorting and effectively improving the working efficiency and reliability of the color sorter.

[0024] Please see Figures 1-4 This utility model provides a technical solution:

[0025] The dual-channel sorting device of the rice color sorter includes a base plate 5, a storage bin 1 is provided above the base plate 5, and a guide rail assembly 3 is installed on the top of the base plate 5 below the storage bin 1. The guide rail assembly 3 includes a main guide rail 31 and two branch guide rails 32 integrally formed on the right side of the main guide rail 31. A paddle motor 34 is installed at the center of the guide rail assembly 3. A paddle plate 36 is coaxially fixed to the output shaft of the paddle motor 34. A horizontal plate 2 is fixedly connected to the outer wall of the storage bin 1. A movable block 22 is slidably installed at the bottom of the horizontal plate 2.

By setting up a base plate 5, a storage bin 1, and a guide rail assembly 3 including a main guide rail 31 and two branch guide rails 32, and cooperating with a paddle motor 34 and a paddle plate 36, the rice is diverted. At the same time, the rice on the guide rail assembly 3 is accurately observed using a sliding observation lens 4. The overall structure allows the rice to enter the dual channels in an orderly manner for sorting, which greatly increases the rice processing capacity per unit time. The sliding design of the observation lens 4 ensures comprehensive monitoring of the rice in both channels, providing a foundation for subsequent accurate sorting and effectively improving the working efficiency and reliability of the color sorter.

[0026] In a preferred embodiment, two collecting plates 35 are symmetrically fixedly connected to one end of the main guide rail 31 near the branch guide rail 32, and the width between the two collecting plates 35 gradually decreases to the right. This can effectively guide and gather the rice about to enter the branch guide rail 32, preventing the rice from scattering or deviating at the branching point, and ensuring that the rice can accurately and evenly enter the two branch guide rails 32.

[0027] In a preferred embodiment, a conveyor belt 33 is installed in both the main guide rail 31 and the branch guide rail 32. A pad 30 is provided at the bottom of the branch guide rail 32, and the pad 30 is fixed to the top of the base plate 5. This allows the rice to be transported smoothly and continuously throughout the guide rail assembly 3, avoiding jamming or accumulation during the rice transport process.

[0028] In a preferred embodiment, the bottom of the storage bin 1 is provided with a feeding pipe 13 facing the main guide rail 31, and a feeding valve 14 is installed on the feeding pipe 13. This ensures that the rice in the storage bin 1 can fall accurately into the main guide rail 31, avoiding deviation during rice feeding; the feeding valve 14 installed on the feeding pipe 13 can flexibly control the feeding speed and amount of rice.

[0029] In a preferred embodiment, a support column 18 is fixedly installed at each of the four corners of the bottom of the storage bin 1. The support columns 18 are fixedly installed on the top of the base plate 5, providing stable support for the storage bin 1 and enhancing the overall structural strength of the storage bin 1. The top of the storage bin 1 is provided with a feeding port 17, and a box cover 11 is installed on the top of the feeding port 17. A handle 12 is fixedly installed on the top of the box cover 11. The feeding port 17 on the top of the storage bin 1 and the box cover 11 with the handle 12 facilitate the addition of rice to the storage bin 1 by the staff, and the box cover 11 can effectively prevent external dust and impurities from entering the storage bin 1 and contaminating the rice, ensuring the cleanliness of the rice to be sorted.

[0030] In a preferred embodiment, a stirring shaft 15 is rotatably mounted inside the storage tank 1. Several stirring blades 16 are fixedly mounted on the outer circumference of the stirring shaft 15. A stirring motor 10 with an output shaft coaxially fixed to the top of the storage tank 1 is fixedly mounted. This allows for thorough stirring of the rice in the storage tank 1, preventing the rice from clumping due to prolonged storage and ensuring that the rice remains loose and is evenly discharged from the discharge pipe 13 during feeding.

[0031] In a preferred embodiment, the horizontal plate 2 has a movable groove 21 inside for the movable block 22 to move. A lead screw 23 is rotatably installed in the movable groove 21 and is threadedly connected to the movable block 22. A drive motor 24, coaxially fixed with the lead screw 23, is installed at the right end of the horizontal plate 2. Driven by the drive motor 24, the movable block 22 can drive the observation lens 4 to achieve precise horizontal movement, thereby allowing the observation lens 4 to observe the different positions of the guide rail assembly 3 in detail.

[0032] In a preferred embodiment, a diagonal brace 20 is fixed to the top of the horizontal plate 2, and the other end of the diagonal brace 20 is fixedly connected to the outer wall of the storage box 1. This enhances the structural stability of the horizontal plate 2 when supporting components such as the observation lens 4.

[0033] In use, the dual-channel sorting device of this utility model's rice color sorter first allows the operator to open the feeding port 17 through the lid 11 with handle 12 on the top of the storage bin 1, and pour the rice to be sorted into the storage bin 1. The lid 11 prevents external dust and impurities from entering. The support columns 18 at the four corners of the bottom of the storage bin 1 ensure that it is stably installed on the base plate 5. The stirring motor 10 inside the storage bin 1 drives the stirring shaft 15 and stirring blades 16 to rotate, thoroughly stirring the rice to prevent clumping and ensure that the rice is in a loose state.

[0034] Subsequently, the discharge pipe 13 at the bottom of the storage bin 1 is aligned with the main guide rail 31. The discharge valve 14 controls the discharge speed and amount of rice, ensuring that the rice falls precisely into the main guide rail 31. The conveyor belt 33 within the main guide rail 31 and the branch guide rail 32 starts, driving the rice along the guide rail assembly 3. When the rice is transported to the connection between the main guide rail 31 and the branch guide rail 32, the paddle motor 34 at the center of the guide rail assembly 3 drives the paddle plate 36 to rotate. This, in conjunction with two symmetrically arranged and gradually decreasing width collection plates 35, and the observation lens 4, evenly distributes the rice according to color to the two branch guide rails 32, achieving initial diversion of the dual-channel sorting. That is, based on the color of the rice observed by the observation lens 4, the paddle plate 36 moves rice of different colors into the two branch guide rails 32, thus achieving color sorting of the rice.

[0035] During the rice conveying process, the bottom of the horizontal plate 2 fixed to the outer wall of the storage box 1 is rotated by the drive motor 24, which drives the lead screw 23 to rotate, causing the movable block 22 to slide along the movable groove 21, thereby driving the observation lens 4 to move horizontally. The diagonal support rod 20 at the top of the horizontal plate 2 enhances the structural stability, ensuring that the observation lens 4 can be directly aligned with the guide rail assembly 3, allowing for comprehensive and accurate observation and monitoring of the rice on the two branch guide rails 32 and the main guide rail 31.
