[0051] The specific embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. It should be understood that the specific embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0052] The crop seed vitality intelligent 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 a crop seed vitality intelligent sorting equipment, wherein the crop seed vitality intelligent sorting equipment comprises:

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

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

[0056] The unloading device 3 includes a sorting guide component 31, a good product tube 32 and a bad product tube 33. The sorting guide component 31 is arranged at the unloading station of the conveying device 1 and is communicatively connected with the detection device 2. The sorting guide component 31 selects and guides the seeds to the good product tube 32 or the bad product tube 33 according to the detection results of the detection device 2.

[0057] When the above-mentioned crop seed vitality intelligent sorting equipment is used, the conveying device 1 conveys the seeds from the loading station to the unloading station, and 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 variety seeds and bad variety seeds. The unloading device 3 includes a sorting guide component 31, a good product tube 32 and a bad product tube 33. The good product tube 32 is used to correspondingly transmit good variety seeds, and the bad product tube 33 is used to correspondingly transmit bad variety seeds. The sorting guide component 31 is communicatively connected with the detection device 2, and guides the seeds to the corresponding pipeline according to the detection results. Then, through the crop seed vitality intelligent sorting equipment, automatic sorting of seeds can be realized, the workload of operators can be reduced, and the efficiency of seed screening can be effectively improved.

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

[0059] Specifically, the number of the detection devices 2 is set to two, and the accuracy of the detection result is improved by performing a secondary detection on the seeds.

[0060] Furthermore, the detection device 2 can be configured as a combination mechanism based on laser spectroscopy technology. The detection device 2 includes a laser emitter arranged above the conveying device 1 and a spectrometer arranged 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. The spectral information data of the seeds to be detected can be obtained through the spectrometer. The spectrometer then sends the spectral information data to the control system to perform calculations, processing and analysis on the spectral information data and can determine the activity state of the seeds to be detected, and mark the seeds as good varieties and bad varieties according to the activity state of the seeds. The sorting guide component 31 selects and guides the seeds to the good quality tube 32 when the detection result is a good variety, and selects and guides the seeds to the bad quality tube 33 when the detection result is a bad variety.

[0061] like Figure 1 , Figure 5 and Figure 6As shown, in the embodiment of the present invention, a loading fixture 11 is provided on the conveying device 1, and the loading fixture 11 includes a first carrier plate 111 and a second carrier plate 112 which are assembled to form a loading space 113. The unloading device 3 also includes a separation mechanism 34 arranged on the unloading station, and the separation mechanism 34 can apply force to the loading fixture 11 to separate the first carrier plate 111 and the second carrier plate 112. The sorting guide assembly 31 includes a unloading pipe 311 and a pipe mouth switching mechanism 312. The unloading pipe 311 is mounted below the loading space 113, and the upper end of the unloading pipe 311 can be arranged directly opposite to the loading space 113 to receive seeds from the loading space 113. The lower end of the unloading pipe 311 is forked and connected with a good quality pipe 32 and a defective quality pipe 33. The pipe mouth switching mechanism 312 is arranged at the lower end of the unloading pipe 311 and is communicatively connected with 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 a spliced ​​state, and the seeds can be placed in the loading space 113 by manual or automated equipment. After the loading fixture 11 runs to the unloading station, the separation mechanism 34 applies force to the first carrier plate 111 and the second carrier plate 112, so that the two carrier plates are separated to open the loading space 113, so that the seeds naturally fall into the unloading tube 311, and the automatic operation of unloading the seeds is realized. In addition, through the detection device 2, the control system can determine whether the seeds are good products. If the control system determines that the seeds are good products, the nozzle switching mechanism 312 is controlled to close the entrance of the bad product tube 33, and the seeds are guided to the collection container of good seeds along the good product tube 32. If the control system determines that the seeds are bad products, the nozzle switching mechanism 312 is controlled to close the entrance of the good product tube 32, and the seeds are guided to the collection container of bad seed along the bad product tube 33, thereby realizing the automatic sorting of seeds and improving the sorting efficiency.

[0063] It can be understood that when the above technical solution is adopted, the crop seed vitality intelligent sorting equipment first unloads the seeds and then performs the sorting operation. Therefore, the two steps of unloading and sorting do not affect each other. Multiple loading jigs 11 can be set on the conveying device 1, and multiple unloading devices 3 can be set at the unloading station. The good quality pipes 32 and bad quality pipes 33 of the multiple unloading devices 3 are respectively connected to two collecting containers. The control system can control the conveying device 1 to transport multiple loading jigs 11 to the unloading station at one time, and then control each unloading device 3 to process the seeds carried by a loading jig 11, thereby realizing batch sorting and further improving work efficiency.

[0064] Of course, the present invention is not limited to this. Two separation mechanisms 34 can also be directly set at the unloading station, and a container for collecting good seeds is set under one separation mechanism 34, and a container for collecting bad seeds is set under the other separation mechanism 34. The control system controls the conveying device 1 to transport the carrier jig 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, and the sorting guide component 31 can be cancelled, but only one carrier jig 11 can be processed at a time, and the efficiency is reduced compared to the scheme of setting the sorting guide component 31.

[0065] Specifically, a through hole is formed below the loading space 113, and the through hole is also composed of a first carrier plate 111 and a second carrier plate 112. The through hole is tapered from top to bottom, and the minimum aperture 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 loading 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, the turntable 12 is provided with connection holes for fixing the material loading fixture 11, and the turntable 12 is also provided with through holes corresponding to the material loading fixture 11. Of course, in other embodiments of the present invention, the conveying device 1 can also be configured as a conveyor belt for transmission along a straight line.

[0067] like Figures 2 to 4 As shown, in an embodiment of the present invention, the feed tube includes a feed tube main section and a first interface and a second interface forked from the lower end of the feed tube main section. The first interface and the second interface are respectively connected to a good quality tube 32 and a bad quality tube 33 in one-to-one correspondence. The tube mouth switching mechanism 312 includes a baffle body 3122 and a baffle driving member 3121. The baffle body 3122 is rotatably placed in the inner cavity at the lower end of the feed tube 311. The baffle driving member 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 closing.

[0068] See also Figure 4, the baffle body 3122 is tilted against the inner wall of the main feeding section 3111 close to the good quality tube 32, the first interface is closed, and the baffle body 3122 forms a guiding slope tilted toward the bad quality tube 33, so that the seeds can smoothly enter the bad quality tube 33, and vice versa. Obviously, compared with the solution of directly covering the baffle body 3122 horizontally on the good quality tube 32 or the bad quality tube 33, the inclined baffle body 3122 will not cause the accumulation of seeds. On the one hand, it can ensure that the seeds can be discharged from the feeding tube 311 to avoid the seeds accumulating in the feeding tube 311 and rotting; on the other hand, it can avoid the blockage in the feeding tube 311; on the other hand, when the baffle body 3122 rotates, the good quality tube 32 and the bad quality 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 another pipeline, causing sorting failure and affecting subsequent agricultural production.

[0069] Specifically, see Figure 2 and Figure 3 The main feed section is set as a square tube; the bifurcated branch section 3112 is composed of two square tubes, and the height of the adjacent side walls of the two square tubes is less than the height of the opposite side walls of the two square tubes, so as to be used for installing the baffle body 3122.

[0070] like Figure 2 and Figure 5 As shown, in an embodiment of the present invention, the nozzle switching mechanism 312 also includes a rotating seat 3123, the rotating seat 3123 includes a rotating shaft portion 3124 and a connecting portion 3125, the rotating shaft portion 3124 is rotatably arranged on the discharge tube 311, the first end of the rotating shaft portion 3124 extends into the inner cavity of the lower end of the discharge tube 311, and the second end of the rotating shaft portion 3124 extends out of the inner cavity of the discharge tube 311, the baffle body 3122 is arranged on the first end of the rotating shaft portion 3124, and the connecting portion 3125 extends from the second end of the rotating shaft portion 3124 toward a side biased toward the good tube 32 or the defective tube 33, and the baffle driving member 3121 is a telescopic driving member, and the telescopic end of the telescopic driving member is hinged to the connecting portion 3125.

[0071] By setting a rotating seat 3123, the telescopic movement of the telescopic drive component can be converted into the rotational movement of the baffle body 3122. The telescopic drive component can be pneumatically controlled. Compared with the solution of setting a rotating drive component to directly drive the baffle body 3122, the telescopic drive component has a simple structure and lower cost. The inner side wall of the main blanking section 3111 can limit the baffle body 3122, and there is no need to precisely control the rotation angle of the baffle body 3122.

[0072] Specifically, the connecting portion 3125 is bent and extended upward in a direction away from the rotating shaft portion 3124; the telescopic driving member is installed on the discharge tube 311 through a bent connecting plate, and the telescopic driving member can realize a certain angle of rotation on the connecting plate.

[0073] like Figure 5 and Figure 6 As shown, in the embodiment of the present invention, the first carrier plate 111 and the second carrier plate 112 are each provided with a rotating portion 116 and a driving portion 117 at opposite ends, each rotating portion 116 can be rotatably arranged on the conveying device 1, a reset member 115 is connected between the driving portions 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 driven and connected to the separation driving member 341, the separation driving member 341 is used to drive the separation block 342 to extend between the driving portions 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, and the reset member 115 is used to drive the first carrier plate 111 and the second carrier plate 112 to be spliced ​​when the separation driving member 341 drives the separation block 342 to exit.

[0074] The separation driving member 341 drives the separation block 342 to be inserted between the first carrier plate 111 and the second carrier plate 112. The separation block 342 abuts against the driving parts 117 of the two carrier plates to apply a thrust to the two carrier plates to swing backwards, so that the two carrier plates are separated. At the same time, the reset member 115 is stretched. When the separation block 342 withdraws from 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 member is a tension spring, and both ends of the tension spring are respectively connected to the driving parts 117 of the two carriers. Of course, the present invention is not limited thereto, and the reset member 115 can also be set as an elastic rubber belt or the like.

[0076] like Figure 5 and Figure 6 As shown, in the embodiment of the present invention, the separation block 342 includes a connecting main board portion 3421 and a separation tip portion 3422, the connecting main board portion 3421 is connected to the driving end of the separation driving member 341, and the end of the separation tip portion 3422 away from the connecting main board portion 3421 is arranged in a tapered manner along the connecting main board portion 3421 toward the material carrier 11, and the driving portions 117 of the first carrier plate 111 and the second carrier plate 112 are both extended from the corresponding carrier plates and bent and extended close to each other to enclose an insertion port for the separation tip portion 3422 to extend into. The separation driving member 341 drives the separation block 342 to move toward the insertion port, and the separation tip portion 3422 abuts against the driving portions 117 of the two carrier plates. As the separation tip portion 3422 moves, the two carrier plates gradually swing away from each other, and the rotation process is smoother.

[0077] Specifically, a slide rail is provided on the lower side of the connecting main board portion 3421 , and the connecting main board portion 3421 is configured as a sliding block.

[0078] like Figure 6 As shown, in the embodiment of the present invention, both sides of the separation tip portion 3422 are provided with a limit portion 3423, and the limit portion 3423 is formed with a limit plane arranged in the back of the main board portion 3421, and the limit portion 3423 is used to abut against the driving portion 117 for limiting. The separation drive member 341 drives the separation block 342 to move toward the insertion port, and when the separation tip portion 3422 abuts against the driving portions 117 of the two carriers, the two carriers will swing away from each other with the movement of the separation tip portion 3422. When the separation block 342 moves to the limit portion 3423 abuts against the driving portion 117, the thrust direction of the separation drive member 341 on the driving portion 117 points to the rotating portion 116 of the carrier, and the movable direction of the carrier is perpendicular to the force direction, and the carrier will not swing any more, thereby realizing the limitation of the maximum swing angle of the carrier, so as to prevent the separation distance of the two carriers from exceeding the working stroke of the reset member 115, and improve the service life of the reset member 115.

[0079] like Figure 5 As shown, in an embodiment of the present invention, the driving portion 117 is provided with a horizontally rotatable pulley body 114, and the separation tip portion 3422 is in contact with the pulley body 114, thereby converting the sliding friction between the separation tip portion 3422 and the driving portion 117 into rolling friction, so as to reduce wear and reduce noise.

[0080] like Figure 7 and Figure 8 As shown, in an embodiment of the present invention, the crop seed vitality intelligent sorting equipment also includes a feeding device 4, the feeding device 4 includes a feeding shell 41, a roller body 42 and a roller driving member 43, a roller installation space 411 is formed in the feeding shell 41, a feeding pipe 412 connected to the roller installation space 411 is arranged at the top of the feeding shell 41, the roller body 42 is placed in the roller installation space 411 and is rotatably arranged to fit the inner wall of the feeding shell 41, and a feeding port 413 for exposing the annular surface of the roller body 42 is formed on the upper side of the roller installation space 411, and a discharge port 414 for exposing the annular surface of the roller body 42 is formed on the lower side of the roller installation space 411, the conveying device 1 is located below the discharge port 414, and a transfer hole 421 for accommodating a single seed is opened on the annular surface of the roller body 42, and the roller driving member 43 is used to drive the roller body 42 to rotate.

[0081] When the above-mentioned feeding device 4 is used, the seeds enter the roller installation space 411 from the feeding pipe 412. Since the roller body 42 fits the inner wall of the feeding shell 41, the seeds cannot directly pass through the roller installation space 411, and can only enter the transfer hole 421 of the roller body 42 from the feeding port 413. Then the roller driving member 43 drives the roller body 42 to rotate, so that the transfer hole 421 facing the feeding port 413 faces the feeding port 413, and finally the seeds fall from the discharge port 414 onto the loading fixture 11 of the conveying device 1. Then, through the feeding device 4, a single seed can be placed on the loading fixture 11. In the detection stage, the detection device 2 can detect a seed at a time to avoid the situation where multiple seeds are mixed together and cause detection errors, thereby ensuring the detection accuracy. When manually feeding, the operator can fill the seeds into the feeding pipe 412 in batches without discharging seeds one by one, which further reduces the labor intensity of the operator and improves the seed sorting efficiency.

[0082] Specifically, four transfer holes 421 are provided on the roller body 42, and the four transfer holes 421 are arranged at equal angles along the annular surface of the roller body 42; of course, according to the running speed of the conveying device 1 and the running speed of the roller driving member 43, the number of the transfer holes 421 can also be set to other numbers.

[0083] like Figure 8 As shown, in the embodiment of the present invention, the inner wall of the feeding shell 41 includes a first side wall 415 and a second side wall 416 which are fitted with the annular surface of the roller body 42, the first side wall 415 is inclined toward the second side wall 416 in a top-to-bottom direction, and a guide portion 417 extending toward the first side wall 415 is formed on the upper side of the second side wall 416, the guide portion 417 and the second side wall 416 are spaced apart to form a feed port 413, the lower end face of the guide portion 417 is fitted with the annular 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 shell 41, and the feed connecting pipe 412 is arranged on the upper side of the guide portion 417.

[0084] Specifically, the rotation direction of the upper side of the roller body 42 is from the first side wall 415 to the second side wall 416, and a gradually expanding space is formed between the roller body 42 and the first side wall 415. During the rotation of the roller body 42, due to the friction force, the roller body 42 will drive the seeds to move from bottom to top. Since the space on the upper side is gradually expanded, the movement space of the seeds can be increased to prevent the seeds from being squeezed and damaged. On the one hand, the guide part 417 can guide the seeds to the side close to the first side wall 415 at a slower speed, and on the other hand, it can push away the seeds accumulated above the transfer hole 421. In this way, during the rotation of the roller body 42, except for the seeds entering the transfer hole 421, other seeds tend to move upward under the action of friction, and the upper space gradually becomes larger, which can prevent the seeds from being squeezed and damaged.

[0085] like Figure 1 and Figure 7 As shown, in the embodiment of the present invention, there are multiple feeding shells 41, and multiple feeding shells 41 are arranged in sequence along the conveying direction of the conveying device 1. The number of roller bodies 42 is set corresponding to the number of feeding shells 41, and each roller body 42 is provided with a driven shaft axially extending out of the feeding shell 41. The feeding device 4 also includes a hopper 46, a transmission shaft 44 and a transmission belt 47. The hopper 46 is respectively connected to the feed pipes 412 of the multiple feeding shells 41. The transmission shaft 44 is connected to the driving end of the roller driving member 43. The number of the transmission belt 47 is set corresponding to the number of the roller bodies 42, and the transmission belt 47 is wound around the driven shaft and the transmission shaft 44. Then, through the setting of the transmission belt 47 and the transmission shaft 44, multiple roller bodies 42 can be synchronously driven to rotate by a single roller driving member 43. The operator only needs to pour the seeds into the hopper 46 to load multiple loading jigs 11 at one time, which further improves the efficiency of seed sorting. Correspondingly, the number of the loading shells 41 is set corresponding to the number of the unloading devices 3. In a specific embodiment of the present application, the number of both is set to ten.

[0086] Specifically, a plurality of partition plates are disposed inside the hopper 46 to separate and form a plurality of channels inside the hopper 46 , and each channel is connected to a corresponding feed pipe 412 through a pipeline.

[0087] Specifically, the feeding device 4 also includes a feeding rack, which has two side vertical plates and a mounting horizontal plate arranged between the two side vertical plates. The hopper 46 is installed between the two side vertical plates. The mounting horizontal plate is arranged in an arc shape, and multiple feeding shells 41 are arranged in sequence along the mounting horizontal plate.

[0088] Furthermore, the feeding device 4 also includes an adjusting plate assembly 48, and the adjusting plate assembly 48 includes a fixed mounting block, a movable mounting block and an adjusting bolt. The fixed mounting block is fixedly arranged on the lower side of the mounting cross plate, and the movable mounting block is movably mounted on the lower side of the mounting cross plate. The mounting shell 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 screwing the adjusting bolt, the spacing 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 an embodiment of the present invention, the crop seed vitality intelligent sorting equipment also includes a shortage of material identification device and a feeding device which are arranged in sequence along the feeding device 4 toward the detection device 2. The shortage of material identification device and the feeding device are both communicatively connected to the control system. The shortage of material identification device is used to detect whether there are seeds in the loading jig 11, and then send the detection data to the control system. When the control system determines that there are no seeds in the loading jig 11, the feeding device is controlled to feed the loading jig 11, thereby ensuring that each loading jig 11 passing through the detection device 2 is loaded with seeds.

[0090] Specifically, the lack of material identification device can be set as a camera, the camera collects the picture of the upper side of the loading fixture 11 and sends it to the control system, and the control system determines whether there are seeds in the loading fixture 11 through the image recognition algorithm; or the lack of material identification device is set as an infrared sensor, and a through hole is opened below the loading space 113. The size of the through hole is smaller than the seed size but can be used for the infrared light sent by the infrared sensor to pass through. If there are seeds in the loading space 113, the infrared light cannot pass through the loading fixture 11. The control system can determine whether there are seeds in the loading fixture 11 according to the detection result of the infrared sensor. The structure of the feeding device can be set according to the structure of the feeding device 4, which will not be repeated here.
