[0051] The specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0052] The intelligent crop seed viability sorting equipment of the present invention is described below with reference to the accompanying drawings.

[0053] like Figures 1 to 4 As shown, the present invention provides an intelligent crop seed vigor sorting device, wherein the intelligent crop seed vigor sorting device includes:

[0054] Conveying device 1, used for conveying seeds;

[0055] The detection device 2 is located between the loading station and the unloading station of the conveying device 1. The detection device 2 is used to detect the seeds.

[0056] The feeding device 3 includes a sorting guide component 31, a good quality tube 32, and a defective quality tube 33. The sorting guide component 31 is located at the feeding station of the conveying device 1 and is connected to the detection device 2. The sorting guide component 31 guides the seeds to the good quality tube 32 or the defective quality tube 33 according to the detection result of the detection device 2.

[0057] When using the above-mentioned intelligent crop seed vigor sorting equipment, the conveying device 1 transports the seeds from the loading station to the unloading station. The detection device 2 is used to detect the seeds. Based on the detection results of the detection device 2, the seeds can be classified into good varieties and bad varieties. The unloading device 3 includes a sorting guide component 31, a good quality tube 32, and a bad quality tube 33. The good quality tube 32 is used to transport good varieties, and the bad quality tube 33 is used to transport bad varieties. The sorting guide component 31 is communicatively connected to the detection device 2 and guides the seeds to the corresponding pipes according to the detection results. Thus, the intelligent crop seed vigor sorting equipment can realize automatic sorting of seeds, reduce the workload of operators, and effectively improve the seed screening efficiency.

[0058] Specifically, the intelligent crop seed viability sorting equipment also includes a corresponding control system. The detection device 2 transmits the detection results to the control system, which then judges the seeds based on the detection data and controls the sorting guide component 31 to adjust the guiding direction of the seeds based on the judgment results.

[0059] Specifically, the number of detection devices 2 is set to two, so as to improve the accuracy of the detection results by performing secondary detection on the seeds.

[0060] Furthermore, the detection device 2 can be configured as a combined mechanism based on laser spectroscopy technology. The detection device 2 includes a laser emitter located above the conveying device 1 and a spectrometer located below the conveying device 1. The conveying device 1 allows the detection light emitted by the laser emitter to pass through. The laser emitter irradiates the seeds, and the spectrometer can acquire the spectral information data of the seeds to be detected. The spectrometer then sends the spectral information data to the control system for calculation, processing, and analysis, and can determine the activity status of the seeds to be detected. Based on the activity status of the seeds, the seeds are marked as good varieties and bad varieties. If the detection result is a good variety, the sorting guide component 31 will guide the seeds to the good quality tube 32, and if the detection result is a bad variety, it will guide the seeds to the bad quality tube 33.

[0061] like Figure 1 , Figure 5 and Figure 6As shown, in this embodiment of the invention, the conveying device 1 is provided with a material-carrying fixture 11, which includes a first carrier plate 111 and a second carrier plate 112 assembled to form a material-carrying space 113. The unloading device 3 also includes a separation mechanism 34 provided at the unloading station. The separation mechanism 34 can apply force to the material-carrying fixture 11 to separate the first carrier plate 111 and the second carrier plate 112. The sorting guide component 31 includes a feeding pipe 311 and a pipe opening switching mechanism 312. The feeding pipe 311 is mounted below the material-carrying space 113, and the upper end of the feeding pipe 311 can be set directly facing the material-carrying space 113 to receive seeds from the material-carrying space 113. The lower end of the feeding pipe 311 is bifurcated and connected to a good quality pipe 32 and a defective quality pipe 33. The pipe opening switching mechanism 312 is provided at the lower end of the feeding pipe 311 and is communicatively connected to the detection device 2 to select one of the good quality pipe 32 and the defective quality pipe 33 for sealing.

[0062] At the loading station, the first carrier plate 111 and the second carrier plate 112 of the loading fixture 11 are in an assembled state. Seeds can be placed into the loading space 113 manually or by automated equipment. After the loading fixture 11 moves to the unloading station, the separating mechanism 34 applies force to the first carrier plate 111 and the second carrier plate 112, causing the two carrier plates to separate and open the loading space 113, allowing the seeds to fall naturally into the unloading pipe 311, thus achieving automated seed unloading. Furthermore, through the detection device 2, the control system can determine whether the seeds are good or not. If the control system determines that the seeds are good, it controls the pipe switching mechanism 312 to close the entrance of the defective pipe 33, and the seeds are guided along the good pipe 32 to the collection container of good seeds. If the control system determines that the seeds are defective, it controls the pipe switching mechanism 312 to close the entrance of the good pipe 32, and the seeds are guided along the defective pipe 33 to the collection container of defective seeds, thereby achieving automated seed sorting and improving sorting efficiency.

[0063] Understandably, when the above technical solution is adopted, the intelligent crop seed viability sorting equipment first feeds the seeds and then performs sorting operations. Therefore, the feeding and sorting steps do not affect each other. Multiple material-carrying fixtures 11 can be set on the conveying device 1, and multiple feeding devices 3 can be set at the feeding station. The good quality tubes 32 and bad quality tubes 33 of the multiple feeding devices 3 are respectively connected to two collection containers. The control system can control the conveying device 1 to transport multiple material-carrying fixtures 11 to the feeding station at one time, and then control each feeding device 3 to process the seeds carried by one material-carrying fixture 11, thereby realizing batch sorting and further improving the work efficiency.

[0064] Of course, the present invention is not limited to this. Alternatively, two separation mechanisms 34 can be set directly at the unloading station. A container for collecting good seeds can be set below one separation mechanism 34, and a container for collecting defective seeds can be set below the other separation mechanism 34. The control system controls the conveying device 1 to transport the material-carrying fixture 11 to one of the two separation mechanisms 34 based on the judgment structure. This scheme sets unloading and sorting as the same operation step, which can eliminate the sorting guide component 31. However, only one material-carrying fixture 11 can be processed at a time, which is less efficient than the scheme with the sorting guide component 31.

[0065] Specifically, a through hole is formed below the material-carrying space 113. The through hole is also formed by the first carrier plate 111 and the second carrier plate 112. The through hole is set in a gradually narrowing manner from top to bottom, and the minimum diameter of the through hole is smaller than the cross-sectional radius of the seed. In this way, the seed can fall into the center of the material-carrying space 113 as much as possible without falling out of the through hole.

[0066] Specifically, the conveying device 1 is configured as a turntable 12, which has a connecting hole for fixing the material-carrying fixture 11, and a through hole corresponding to the material-carrying fixture 11. Of course, in other embodiments of the present invention, the conveying device 1 can also be configured as a conveyor belt that conveys along a straight line.

[0067] like Figures 2 to 4 As shown, in this embodiment of the invention, the feeding pipe includes a main feeding section and a first interface and a second interface formed by branching from the lower end of the main feeding section. The first interface and the second interface are respectively connected to the good quality pipe 32 and the defective quality pipe 33. The pipe switching mechanism 312 includes a baffle body 3122 and a baffle drive 3121. The baffle body 3122 is rotatably placed in the inner cavity of the lower end of the feeding pipe 311. The baffle drive 3121 is communicatively connected to the detection device 2 and is used to drive the baffle body 3122 to select one of the first interface and the second interface for closure.

[0068] See Figure 4The baffle body 3122 is inclined and abuts against the inner wall of the main feeding section 3111 near the good quality tube 32. The first interface is closed, and the baffle body 3122 forms a guide slope inclined towards the defective tube 33, so that the seeds can smoothly enter the defective tube 33, and vice versa, so that the seeds can smoothly enter the good quality tube 32. Obviously, compared with the solution of directly covering the good quality tube 32 or the defective tube 33 with the baffle body 3122 horizontally, the inclined baffle body 3122 will not cause seed accumulation. On the one hand, it can ensure that the seeds can be discharged from the feeding tube 311, avoiding the seeds from accumulating in the feeding tube 311 and rotting. On the other hand, it can prevent the feeding tube 311 from becoming blocked. Furthermore, when the baffle body 3122 rotates, the good quality tube 32 and the defective tube 33 will be in the open state at the same time. If there are seeds accumulated on the baffle body 3122, the seeds may enter the other tube, causing sorting failure and affecting subsequent agricultural production.

[0069] Specifically, see Figure 2 and Figure 3 The main feeding section is made of square tubes; the branch section 3112 is composed of two square tubes joined together, and the height of the adjacent sidewalls of the two square tubes is less than the height of the opposite sidewalls of the two square tubes, so as to install the baffle body 3122.

[0070] like Figure 2 and Figure 5 As shown, in this embodiment of the invention, the tube switching mechanism 312 further includes a rotating seat 3123. The rotating seat 3123 includes a rotating shaft 3124 and a connecting part 3125. The rotating shaft 3124 is rotatably disposed on the feed tube 311. The first end of the rotating shaft 3124 extends into the inner cavity of the lower end of the feed tube 311, and the second end of the rotating shaft 3124 extends out of the inner cavity of the feed tube 311. The baffle body 3122 is disposed on the first end of the rotating shaft 3124. The connecting part 3125 extends from the second end of the rotating shaft 3124 toward the side biased towards the good tube 32 or the defective tube 33. The baffle drive member 3121 is a telescopic drive member, and the telescopic end of the telescopic drive member is hinged to the connecting part 3125.

[0071] By setting a rotating seat 3123, the telescopic motion of the telescopic drive component can be converted into the rotational motion of the baffle body 3122. The telescopic drive component can be pneumatically controlled. Compared with the scheme of setting a rotating drive component to directly drive the baffle body 3122, the telescopic drive component has a simpler structure and lower cost. Furthermore, the inner wall of the feeding main section 3111 can limit and stop the baffle body 3122, eliminating the need for precise control of the rotation angle of the baffle body 3122.

[0072] Specifically, the connecting part 3125 bends upward in a direction away from the rotating shaft part 3124; the telescopic drive is mounted on the feed tube 311 through a bent connecting plate, and the telescopic drive can rotate at a certain angle on the connecting plate.

[0073] like Figure 5 and Figure 6 As shown, in this embodiment of the invention, the first carrier plate 111 and the second carrier plate 112 are each provided with a rotating part 116 and a driving part 117 at opposite ends. Each rotating part 116 is rotatably disposed on the conveying device 1. A reset member 115 is connected between the driving parts 117 of the first carrier plate 111 and the second carrier plate 112. The separation mechanism 34 includes a separation driving member 341 and a separation block 342 drivenly connected to the separation driving member 341. The separation driving member 341 is used to drive the separation block 342 to extend into the driving parts 117 of the first carrier plate 111 and the second carrier plate 112 to separate the first carrier plate 111 and the second carrier plate 112. The reset member 115 is used to drive the first carrier plate 111 and the second carrier plate 112 to be assembled when the separation driving member 341 drives the separation block 342 to retract.

[0074] The separation drive 341 drives the separation block 342 to insert between the first carrier plate 111 and the second carrier plate 112. The separation block 342 abuts against the drive part 117 of the two carrier plates to apply a back-to-back swinging thrust to the two carrier plates, causing the two carrier plates to separate. At the same time, the reset member 115 is stretched. When the separation block 342 exits between the two carrier plates, the two carrier plates are reassembled under the pulling force of the reset member 115 to carry out the next round of sorting operations.

[0075] Preferably, the elastic element is a tension spring, with its two ends connected to the driving portions 117 of the two carrier plates, respectively. However, the invention is not limited to this; the reset element 115 can also be an elastic rubber band, etc.

[0076] like Figure 5 and Figure 6 As shown, in this embodiment of the invention, the separating block 342 includes a connecting main board portion 3421 and a separating tip portion 3422. The connecting main board portion 3421 is connected to the driving end of the separating drive member 341. The end of the separating tip portion 3422 facing away from the connecting main board portion 3421 is gradually tapered in the direction along the connecting main board portion 3421 toward the material carrier fixture 11. The driving portions 117 of the first carrier plate 111 and the second carrier plate 112 both extend from their respective carrier plates and are bent and extended close to each other to form an insertion port for the separating tip portion 3422 to enter. The separating drive member 341 drives the separating block 342 to move toward the insertion port. The separating tip portion 3422 abuts against the driving portions 117 of the two carrier plates. As the separating tip portion 3422 moves, the two carrier plates gradually rotate in opposite directions, making the rotation process smoother.

[0077] Specifically, a slide rail is provided on the lower side of the connecting motherboard part 3421, and the connecting motherboard part 3421 is configured as a slider.

[0078] like Figure 6 As shown in this embodiment of the invention, limiting portions 3423 extend from both opposite sides of the separating tip 3422, and the limiting portions 3423 form limiting planes facing away from the main board portion 3421. The limiting portions 3423 are used to abut against the driving portion 117 for limiting. The separating driving member 341 drives the separating block 342 to move toward the insertion port. When the separating tip 3422 abuts against the driving portion 117 of the two carrier plates, the two carrier plates will swing back and forth as the separating tip 3422 moves. When the separating block 342 moves to the point where the limiting portion 3423 abuts against the driving portion 117, the pushing direction of the separating driving member 341 on the driving portion 117 points to the rotating portion 116 of the carrier plate. Then the movable direction of the carrier plate is perpendicular to the force direction, and the carrier plate will no longer swing, thereby limiting the maximum swing angle of the carrier plate to avoid the separation distance of the two carrier plates from exceeding the working stroke of the reset member 115 and improving the service life of the reset member 115.

[0079] like Figure 5 As shown, in this embodiment of the invention, the drive unit 117 is provided with a horizontally rotatable pulley body 114, and the separation tip 3422 contacts the pulley body 114, thereby changing the sliding friction between the separation tip 3422 and the drive unit 117 into rolling friction, so as to reduce wear and reduce noise.

[0080] like Figure 7 and Figure 8 As shown, in this embodiment of the invention, the intelligent crop seed viability sorting equipment further includes a feeding device 4. The feeding device 4 includes a feeding housing 41, a roller body 42, and a roller drive component 43. A roller mounting space 411 is formed inside the feeding housing 41. A feed pipe 412 communicating with the roller mounting space 411 is provided at the top of the feeding housing 41. The roller body 42 is placed inside the roller mounting space 411 and is rotatably arranged against the inner wall of the feeding housing 41. An inlet 413 is formed on the upper side of the roller mounting space 411 to expose the annular surface of the roller body 42. An outlet 414 is formed on the lower side of the roller mounting space 411 to expose the annular surface of the roller body 42. A conveying device 1 is located below the outlet 414. A transfer hole 421 for accommodating a single seed is opened on the annular surface of the roller body 42. The roller drive component 43 is used to drive the roller body 42 to rotate.

[0081] When using the above-mentioned feeding device 4, seeds enter the roller mounting space 411 from the feed pipe 412. Since the roller body 42 is attached to the inner wall of the feeding housing 41, the seeds cannot pass directly through the roller mounting space 411. Instead, they enter the transfer hole 421 of the roller body 42 from the feed port 413. Then, the roller drive component 43 drives the roller body 42 to rotate, so that the transfer hole 421 facing the feed port 413 faces the feed port 413. Finally, the seeds fall from the discharge port 414 onto the loading fixture 11 of the conveying device 1. With this feeding device 4, individual seeds can be placed on the loading fixture 11. During the detection stage, the detection device 2 can detect one seed at a time, avoiding multiple seeds being mixed together and causing detection errors, thus ensuring detection accuracy. When manually feeding, operators can pour seeds into the feed pipe 412 in batches without having to release seeds one by one, further reducing the labor intensity of operators and improving seed sorting efficiency.

[0082] Specifically, the roller body 42 is provided with four transfer holes 421, which are arranged at equal angular intervals along the annular surface of the roller body 42. Of course, the number of transfer holes 421 can be set to other numbers depending on the operating speed of the conveying device 1 and the operating speed of the roller drive component 43.

[0083] like Figure 8 As shown, in this embodiment of the invention, the inner wall of the feeding housing 41 includes a first sidewall 415 and a second sidewall 416 that are fitted to the circumferential surface of the roller body 42. The first sidewall 415 is inclined toward the second sidewall 416 in a downward direction. A guide portion 417 extending toward the first sidewall 415 is formed on the upper side of the second sidewall 416. The guide portion 417 and the second sidewall 416 are spaced apart to form a feed inlet 413. The lower end face of the guide portion 417 is fitted to the circumferential surface of the roller body 42. The upper end face of the guide portion 417 is spaced apart from the top wall of the feeding housing 41. The feed pipe 412 is located on the upper side of the guide portion 417.

[0084] Specifically, the upper side of the roller body 42 rotates from the first sidewall 415 toward the second sidewall 416, forming a gradually expanding space between the roller body 42 and the first sidewall 415. During the rotation of the roller body 42, due to friction, the roller body 42 will drive the seeds to move from bottom to top. Since the upper space is gradually expanding, it can increase the movement space of the seeds and prevent the seeds from being squeezed and damaged. The guide part 417 can guide the seeds to the side closer to the first sidewall 415 at a relatively slow speed. On the other hand, it can push away the seeds piled up above the transfer hole 421. In this way, during the rotation of the roller body 42, except for the seeds that have entered the transfer hole 421, other seeds tend to move upward under the action of friction, and the upper space gradually increases, which can prevent the seeds from being squeezed and damaged.

[0085] like Figure 1 and Figure 7 As shown, in this embodiment of the invention, there are multiple feeding housings 41, which are arranged sequentially at intervals along the conveying direction of the conveying device 1. The number of rollers 42 corresponds to the number of feeding housings 41, and each roller 42 is provided with a driven shaft extending axially from the feeding housing 41. The feeding device 4 also includes a hopper 46, a drive shaft 44, and a drive belt 47. The hopper 46 is connected to the feed pipes 412 of the multiple feeding housings 41. The drive shaft 44 is connected to the drive end of the roller drive member 43. The number of drive belts 47 corresponds to the number of rollers 42, and the drive belts 47 are wound around the driven shaft and the drive shaft 44. Through the arrangement of the drive belts 47 and the drive shaft 44, multiple rollers 42 can be driven to rotate synchronously by a single roller drive member 43. The operator only needs to pour the seeds into the hopper 46 to feed multiple material-carrying fixtures 11 at one time, further improving the efficiency of seed sorting. Correspondingly, the number of feeding shells 41 is set to correspond to the number of unloading devices 3. In a specific embodiment of this application, the number of both is set to ten.

[0086] Specifically, the hopper 46 is provided with multiple partitions to divide the hopper 46 into multiple channels, and each channel is connected to a feed pipe 412 via a pipeline.

[0087] Specifically, the feeding device 4 also includes a feeding frame, which has two side uprights and a mounting horizontal plate between the two side uprights. The hopper 46 is installed between the two side uprights. The mounting horizontal plate is arc-shaped. Multiple feeding shells 41 are arranged sequentially along the mounting horizontal plate at intervals.

[0088] Furthermore, the feeding device 4 also includes an adjusting plate assembly 48, which includes a fixed mounting block, a movable mounting block, and an adjusting bolt. The fixed mounting block is fixedly disposed on the lower side of the mounting horizontal plate, and the movable mounting block is movably mounted on the lower side of the mounting horizontal plate. The mounting housing is connected to the movable mounting block, and the adjusting bolt passes through the fixed mounting block and is threadedly connected to the movable mounting block. By turning the adjusting bolt, the distance between the movable mounting block and the fixed mounting block can be adjusted to meet the needs of tensioning the transmission belt 47.

[0089] In this embodiment of the invention, the intelligent crop seed viability sorting equipment also includes a material shortage identification device and a material replenishment device arranged sequentially along the feeding device 4 toward the detection device 2. Both the material shortage identification device and the material replenishment device are communicatively connected to the control system. The material shortage identification device is used to detect whether the material carrier 11 is carrying seeds, and then sends the detection data to the control system. When the control system determines that there are no seeds in the material carrier 11, it controls the material replenishment device to replenish the material carrier 11, thereby ensuring that each material carrier 11 passing through the detection device 2 carries seeds.

[0090] Specifically, the material shortage detection device can be a camera that captures an image of the upper side of the material carrier 11 and sends it to the control system. The control system uses an image recognition algorithm to determine whether there are seeds inside the material carrier 11. Alternatively, the material shortage detection device can be an infrared sensor. A through hole is provided below the material carrier space 113. The size of the through hole is smaller than the size of the seed but allows infrared light emitted by the infrared sensor to pass through. If there are seeds in the material carrier space 113, the infrared light cannot pass through the material carrier 11, and the control system can determine whether there are seeds inside the material carrier 11 based on the detection result of the infrared sensor. The structure of the replenishment device can be set according to the structure of the feeding device 4, and will not be described in detail here.
