[0037] Embodiments of the present invention are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0038] In the description of this invention, it should be understood that the orientation descriptions, such as up, down, inside, outside, etc., are based on the orientation or positional relationship shown in the drawings and are only for the convenience of describing this invention and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this invention.

[0039] In the description of this invention, the use of "first" and "second" is for the purpose of distinguishing technical features only, and should not be construed as indicating or implying relative importance or implicitly indicating the number of technical features indicated or the order of the technical features indicated.

[0040] In the description of this invention, unless otherwise explicitly defined, terms such as "set up," "install," and "connect" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this invention in conjunction with the specific content of the technical solution.

[0041] Seed quality is the core value attribute of seeds, which mainly includes seed purity, seed cleanliness, and seed vigor. Seeds with excellent quality can produce high-yield, stable-yield, and high-quality agricultural products. Therefore, seeds usually need to be sorted by sorting devices before leaving the factory.

[0042] Traditional seed sorting relies on purely mechanical methods, which depend on the seeds' physical properties. This method suffers from low efficiency and accuracy, making it difficult to detect and sort damaged, cracked, moldy, or low-vitality seeds. Image analysis technology, however, can achieve non-destructive, non-contact detection based on the spatial information of crop seeds (size, shape, texture, color features, etc.). Therefore, image analysis technology is currently widely used in seed quality inspection. Based on this, existing seed sorting devices typically have visual inspection capabilities, which can improve sorting efficiency. However, during visual inspection, seed overlap and adhesion often occur, leading to poor visual inspection results and low sorting reliability of the device.

[0043] Therefore, some embodiments of the present invention provide a sorting device 1000, as detailed in the accompanying drawings. Figures 1-10 As shown.

[0044] Reference Figure 1 and Figure 2As shown, in this embodiment of the invention, the sorting device 1000 may include: a first conveying component 100, a second conveying component 200, and a visual inspection component 400. The second conveying component 200 may be disposed above the first conveying component 100; specifically, the second conveying component 200 may be mounted on the frame 260. The second conveying component 200 can complete the orderly arrangement of the seeds 2000 and transfer the arranged seeds 2000 to the first conveying component 100, making the seeds 2000 transported in the first conveying component 100 neatly arranged, providing more ideal conditions for subsequent inspection. The first conveying component 100 can be used to convey seeds 2000 from the second conveying component 200. The visual inspection component 400 can be disposed on the upper side of the first conveying component 100 to inspect the seeds 2000. Specifically, the visual inspection component 400 can perform non-destructive and non-contact inspection based on the spatial information (size, shape, texture, color features, etc.) of the crop seeds 2000, thereby detecting and analyzing the quality level of the seeds 2000, and then realizing the sorting of the seeds 2000.

[0045] Reference Figure 2 , Figure 3 and Figure 4 As shown in this embodiment of the invention, the second conveying assembly 200 may include a driving assembly 210, a conveyor belt 220, and a guard plate 230. The driving assembly 210 is used to drive the conveyor belt 220. The conveyor belt 220 may be provided with multiple sets of seed loading assemblies 300 arranged side by side. The multiple sets of seed loading assemblies 300 may be spaced apart along the width direction of the conveyor belt 220. Each set of seed loading assemblies 300 may include multiple seed loading parts 310 for loading seeds 2000. The multiple seed loading parts 310 may be spaced apart along the conveying direction of the conveyor belt 220, thereby ensuring that there is a certain distance between the seed loading parts 310 in the conveyor belt 220, so that the seeds 2000 in the conveyor belt 220 can be relatively independent, reducing the possibility of seeds 2000 sticking together or overlapping.

[0046] Reference Figure 2 , Figure 3 and Figure 5As shown, in this embodiment of the invention, the conveyor belt 220 may have a seed filling area 221, a connecting area 222, and a seed dropping area 223. It can be understood that each region of the conveyor belt 220 can move along the conveying direction. Therefore, the seed filling area 221, connecting area 222, and seed dropping area 223 are not fixed parts of the conveyor belt 220. In this embodiment, the seed filling area 221 can be an upward-facing region of the conveyor belt 220, the seed dropping area 223 can be a downward-facing region of the conveyor belt 220, and the connecting area 222 can be a side-facing region. Specifically, the seed loading device 310, which moves to the seed filling area 221, has an upward-facing opening to receive seeds 2000. It should be noted that the seed filling area 221 can be an inclined planar region. The feeding device can transport the seeds 2000 into the seed filling area 221. The seeds 2000 roll on the conveyor belt 220 until they fall into the seed loading device 310 and are then transported by the conveyor belt 220 to the connecting area 222. It can be understood that the seed filling area 221 is located above the seed dropping area 223, and the connecting area 222 is located between the seed filling area 221 and the seed dropping area 223. A protective plate 230 is located on one side of the connecting area 222 and covers the seed loading component 310 of the connecting area 222. The protective plate 230 can secure the seeds 2000 transported to the connecting area 222 to the seed loading component 310, reducing the risk of the seeds 2000 leaving the seed loading component 310 during transportation. The seed loading component 310 in the seed dropping area 223 has its opening facing downwards, i.e., towards the first conveying component 100, so that the seeds 2000 fall into the first conveying component 100. Under the weight of the load, the seeds 2000 can leave the seed loading component 310 and fall into the conveyor belt 110. The seeds 2000 falling into the conveyor belt 110 are arranged in an orderly manner under the action of the second conveying component 200, providing more ideal conditions for the subsequent visual inspection component 400 to inspect, thereby improving the visual inspection effect and thus improving the sorting accuracy. It should be noted that, in this embodiment of the invention, the conveying direction of the conveyor belt 220 is seed filling area 221 - connecting area 222 - seed dropping area 223.

[0047] In this embodiment of the invention, the drive component 210 in the second conveying component 200 drives the conveyor belt 220 to operate. Seed loading components 300 are arranged side-by-side in the conveyor belt 220. The seed loading parts 310 of the seed loading components 300 can load seeds 2000, allowing the seeds 2000 to be relatively independent and reducing the possibility of seed 2000 sticking together. Seeds 2000 located in the upward-facing seed filling area 221 pass through the connecting area 222. A protective plate 230 on one side of the connecting area 222 secures the seeds 2000 to the seed loading parts 310, ensuring the stability of the seeds 2000 during transportation. The structure reduces the risk of seeds 2000 leaving the seed loading unit 310 during transportation; after passing through the connecting area 222, the seeds 2000 fall from the downward-facing seed dropping area 223 into the first conveying component 100, achieving an orderly arrangement of the seeds 2000 and providing more ideal conditions for subsequent detection; the visual detection component 400 located on the upper side of the first conveying component 100 detects the seeds 2000 in the first conveying component 100, thereby realizing the detection and sorting of the seeds 2000, improving the visual detection effect, thereby improving the sorting accuracy and the reliability of the sorting device 1000.

[0048] Reference Figure 2 and Figure 3 As shown, in this embodiment of the invention, the drive assembly 210 may include a driver, a drive roller 211, a tension roller 212, and a driven roller 213. The driver can be connected to the drive roller 211 and can be a motor, a cylinder, or other driving device. Those skilled in the art can choose the appropriate configuration based on actual conditions; this embodiment does not limit this. The drive roller 211 can be connected to the tension roller 212 and the driven roller 213 via a conveyor belt 220. Specifically, the conveyor belt 220 tightly wraps around the drive roller 211, the tension roller 212, and the driven roller 213 in sequence, so that the horizontal projection of the conveyor belt 220 is triangular. The drive roller 211 can be located diagonally above the driven roller 213, and the tension roller 212 can be located between the drive roller 211 and the driven roller 213 and on one side of the line connecting the drive roller 211 and the driven roller 213, specifically, it can be located below the line connecting the drive roller 211 and the driven roller 213. The seed filling area 221 is located between the driving roller 211 and the driven roller 213. A height difference exists between the driving roller 211 and the driven roller 213, allowing the seed filling area 221 to be set at an angle. The connecting area 222 is located between the driving roller 211 and the tension roller 212. The conveyor belt 220 achieves a change in conveying direction by tightly wrapping around the driving roller 211 and the tension roller 212. The seed dropping area 223 is located between the tension roller 212 and the driven roller 213. The tension roller 212 and the driven roller 213 can be at the same height, allowing the seed dropping area 223 to be set horizontally, enabling the seeds 2000 in the seed dropping area 223 to fall more smoothly into the conveyor belt 110.

[0049] Reference Figure 3 , Figure 4 and Figure 7 As shown, in this embodiment of the invention, the seed loading component 310 may include a seed loading groove 311 suitable for placing seeds 2000. The seeds 2000 can be loaded in the seed loading groove 311 and move with the conveyor belt 220. The seed loading groove 311 may be such that the seeds 2000 are below the surface of the conveyor belt 220, which reduces the possibility of the seeds 2000 falling off the seed loading component 310. It is understood that there is a possibility that residual seeds 2000 or seed debris may exist in the seed loading trough 311 after passing through the seed dropping area 223. To avoid residual seeds 2000 and debris affecting the subsequent loading of the seed loading trough 311, in this embodiment of the invention, the conveyor belt 220 may also have a seed cleaning area 224 located between the seed dropping area 223 and the seed filling area 221. The second conveying assembly 200 may also include a seed cleaning plate 240 located in the seed cleaning area 224. Each seed assembly 300 may also include a seed cleaning trough 320, which may extend along the conveying direction of the conveyor belt 220 to connect the seed loading trough 311 of the seed loading component 310 in the same group. The seed cleaning plate 240 passes through the seed cleaning trough 320. Specifically, the two ends of the seed loading component 310 may be provided with notches 3121, which may connect the seed loading trough 311 and the seed cleaning trough 320 respectively. When the seed loading component 310 moves to the seed cleaning area 224 along the conveyor belt 220, the seed cleaning plate 240 can pass through the notch 3121 along the seed cleaning groove 320 and enter the seed loading groove 311. The seed cleaning plate 240 can push away the residual seeds 2000 or debris in the seed loading groove 311, thereby ensuring the cleanliness of the seed loading groove 311 and providing more ideal conditions for subsequent loading of the seed loading groove 311. It should be noted that in this embodiment of the invention, the conveying direction of the conveyor belt 220 is seed filling area 221 - connecting area 222 - seed dropping area 223 - seed cleaning area 224.

[0050] Reference Figure 3 , Figure 5 and Figure 6 As shown in this embodiment of the invention, each seed assembly 300 may further include multiple mounting slots 330 disposed on the conveyor belt 220. Each mounting slot 330 corresponds one-to-one with a multiple seed loading component 310. The seed loading component 310 is detachably installed within the mounting slot 330, thereby achieving rapid installation of the seed loading component 310. This embodiment allows for the targeted selection of seed loading components 310 of corresponding sizes based on the size of the seeds 2000, improving the versatility of the sorting device 1000. The rapid detachable connection method significantly reduces the difficulty of replacing the seed loading component 310 and improves the efficiency of replacing the seed loading component 310. In this embodiment of the invention, the seed loading component 310 and the mounting slot 330 can be connected by snap-fit, magnetic connection, or screw connection. Those skilled in the art can choose the appropriate setting based on actual conditions; this embodiment does not limit this.

[0051] Reference Figure 5 , Figure 6 and Figure 7 As shown, in this embodiment of the invention, each seed assembly 300 may further include two fixing slots 340, which are respectively disposed on opposite sides of the mounting slot 330, and the fixing slots 340 may communicate with the mounting slot 330. The seed loading component 310 may include a loading part 312 and two mounting parts 313, wherein the seed loading slot 311 may be disposed on the loading part 312, and the two mounting parts 313 are respectively connected to the loading part 312. The two mounting parts 313 are correspondingly inserted into the two fixing slots 340, so that the loading part 312 is fixed in the mounting slot 330. The two mounting parts located on both sides of the loading part 312 can improve the firmness of the seed loading component 310 installation and improve the stability of the seed loading component 310. It should be noted that the two mounting parts 313 and the loading part 312 may be integrally formed or separate, and this embodiment does not limit this.

[0052] Reference Figure 3 , Figure 4 and Figure 6 As shown, in this embodiment of the invention, two adjacent seed assembly components 300 are staggered. Specifically, the seed loading parts 310 in two adjacent seed assembly components 300 are staggered, which can prevent the seeds 2000 from interfering with each other after falling onto the conveyor belt 110 and improve the relative independence between the seeds 2000.

[0053] Reference Figure 2 and Figure 3 As shown in this embodiment of the invention, the second conveying assembly 200 further includes a plurality of partitions 250 disposed in the seed filling area 221, with the partitions 250 respectively disposed between two adjacent seed loading assemblies 300. The partitions 250 can extend upward from the surface of the conveyor belt 220. The arrangement of the partitions 250 can enable the seeds 2000 in the seed filling area 221 to fall into the seed loading unit 310 more quickly, and can also improve the relative independence between the seeds 2000, reducing the possibility of the seeds 2000 sticking together.

[0054] It should be noted that existing visual inspection devices can only acquire image information from a single viewpoint of the seed 2000. This means that current technology cannot fully capture the image information of the seed 2000, resulting in poor accuracy in seed 2000 detection and sorting. Based on this, referring to... Figure 1 , Figure 2 and Figure 9As shown, in this embodiment of the invention, the visual inspection component 400 may include a camera device 410 and a prism 420. The prism 420 may be positioned above the first conveying component 100 and below the camera device 410, i.e., between the two. The prism 420 has a through-slot 430, with its two ends corresponding to the camera device 410 and the seeds 2000 in the first conveying component 100, respectively. The inner wall of the through-slot 430 is a reflector, and the cross-sectional area of ​​the prism 420 gradually increases from bottom to top along its height. The inclined arrangement of the inner wall of the prism 420 can also feed back image information from the sides of the seeds 2000 to the camera device 410, thereby acquiring multi-directional image information of the seeds 2000, improving the comprehensiveness of the seed image information, and thus enhancing the visual inspection effect and sorting accuracy.

[0055] Reference Figure 8 As shown, in this embodiment of the invention, the prism 420 groups can be arranged in two rows, and each prism 420 group can include multiple prisms 420. The two rows of prism 420 groups can be staggered. This embodiment can increase the number of seeds 2000 detected by the visual detection component 400 in a single operation, thereby improving detection efficiency.

[0056] Reference Figure 1 , Figure 2 and Figure 10 As shown, in this embodiment of the invention, the sorting device 1000 may include a plurality of spray valves 500 arranged side by side. Each spray valve 500 is electrically connected to the vision inspection component 400. The spray valves 500 are located on one side of the output end of the first conveying component 100 and are used to blow the seeds 2000. It can be understood that the seeds 2000 move along the conveying direction under the drive of the conveyor belt 110 and are finally discharged at the output end of the conveyor belt 110. Based on this, the spray valves 500 can blow seeds 2000 defined as non-compliant away from the predetermined discharge route according to the detection results of the vision inspection component 400, thereby achieving the sorting of the seeds 2000.

[0057] Reference Figure 10 As shown, in this embodiment of the invention, the spray valve 500 may include a jet nozzle 510 and a main body 520, wherein the jet nozzle 510 may be fixed to the main body 520. Multiple spray valves 500 may be provided, and these multiple spray valves 500 may be arranged side-by-side. The sorting device 1000 may also include a slide block 600, and multiple spray valves 500 may be slidably connected to the slide block 600 respectively, thereby allowing the position of the spray valves 500 to be moved according to the distribution of the seeds 2000, improving the versatility of the sorting device 1000.

[0058] In this embodiment of the invention, both the conveyor belt 220 and the seed loading component 310 are made of flexible materials. Specifically, the conveyor belt 220 and the seed loading component 310 can be manufactured by 3D printing from materials such as thermoplastic polyurethane rubber or nylon. The flexible conveyor belt 220 and the seed loading component 310 can reduce the possibility of damaging the seeds 2000.

Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
