DETAILED DESCRIPTION

[0032] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings. It should be understood that the specific embodiments described herein are only used to explain the present invention and do not constitute a limitation of the present invention.

[0033] The fluorescent seed sorting device provided by the present invention will be described in detail below.

[0034] Figure 1-Figure 3 The three-dimensional structure, the front view structure and the top view structure of the fluorescent seed sorting device provided by the embodiment of the present invention are respectively shown.

[0035] Figure 1-Figure 3 As shown, the fluorescent seed sorting device provided by the present invention includes: a feeding vibrator 1, a conveyor belt mechanism 2, an image processing system 3, a sorting mechanism 4 and a control system. The feeding vibrator 1 is used to scatter the seeds uniformly on the conveyor belt mechanism 2 in order at a certain interval. The feeding vibrator 1 will scatter the mixed ordinary seeds that do not contain fluorescent protein and the fluorescent seeds that contain fluorescent protein on the conveyor belt mechanism 2 at the same time; the conveyor belt mechanism 2 is used to realize the transmission of seeds, and during this process, the ordinary seeds and the fluorescent seeds are transmitted synchronously; the image processing system 3 is arranged above the conveyor belt mechanism 2, and is used to realize the fluorescence excitation and recognition of the fluorescent seeds during the seed transmission process; the control system is used to generate a control instruction for absorbing the fluorescent seeds after the image processing system 3 recognizes the fluorescent seeds, and send it to the sorting mechanism 4; the sorting mechanism 4 is used to receive the control instruction sent by the control system to realize the sorting of the fluorescent seeds and select the fluorescent seeds from the ordinary seeds.

[0036] Figure 4 The structure of the feeding vibrator provided by the embodiment of the present invention is shown.

[0037] like Figure 4As shown, the feeding vibrator includes a vibrating feeding tray 101, a groove bracket 102 and a groove 103. The vibrating feeding tray 101 is used to store seeds. The vibrating feeding tray 101 has a spiral groove inside to sequentially transfer the seeds to the groove 103; the number of grooves 103 is determined according to the width of the conveyor belt mechanism, and multiple grooves 103 are respectively supported on the groove bracket 102, one end of the multiple grooves 103 is connected to the discharge port of the vibrating feeding tray 101, and the other ends of the multiple grooves 103 are arranged at equal intervals and fit with the conveyor belt mechanism. The multiple grooves 103 are used to sort and organize the seeds to ensure that the seeds are arranged in order and fall onto the conveyor belt mechanism 2; the height of the groove bracket 102 is adjustable to ensure that the end of the groove 103 fits with the conveyor belt mechanism.

[0038] In a specific embodiment of the present invention, the vibrating loading tray 101 and the channel bracket 102 can be fixed on the loading base plate 04, and the loading base plate 04 is a flat plate to ensure the stability of the loading vibrator.

[0039] Figure 5 The structure of the conveyor belt mechanism provided by the embodiment of the present invention is shown.

[0040] like Figure 5 As shown, the conveyor belt mechanism includes a conveyor belt 201, a conveyor belt frame 202, a brush fixing plate 203 and a brush 204. The end of the groove 103 is in contact with the conveyor belt 201 to evenly scatter the seeds onto the conveyor belt 201. The conveyor belt 201 is mounted on the conveyor belt frame 202. The brush fixing plate 203 has a concave structure with both ends fixed to the bottom side of the conveyor belt 201. The recessed portion in the middle of the brush fixing plate 203 maintains a certain distance from the conveyor belt 201 to leave installation space for the brush 204. The brush 204 is fixed on the brush fixing plate 203, and the bristles of the brush 204 are in contact with the conveyor belt 201. During the circulation of the conveyor belt 201, residues and other dirt are removed by the brush 204 to ensure that the conveyor belt 201 is clean and prevent pollutants from interfering with image acquisition of the image processing system 3.

[0041] In some embodiments of the present invention, hole arrays 205 are evenly spaced on both sides of the conveyor belt 201 for calibrating the position and speed of the conveyor belt 201 .

[0042] Figure 6 The structure of the image processing system provided by the embodiment of the present invention is shown.

[0043] like Figure 6As shown, the image processing system includes a fixed frame 301, a light source 302, a camera 303, an adjustment frame 304 and an image processor. The light source 302 and the camera 303 are respectively adjustable and fixed on the fixed frame 301 through the adjustment frame 304, so that the light source 302 and the camera 303 have a certain posture adjustment function. The light source 302 is used to illuminate the seeds on the conveyor belt 201 and stimulate the fluorescent signal of the fluorescent seeds. Since ordinary seeds do not contain fluorescent proteins, they will not be stimulated to emit fluorescent signals under the illumination of the light source 302, while the fluorescent seeds contain fluorescent proteins and can be stimulated to emit fluorescent signals under the illumination of the light source 302.

[0044] The camera 303 is used to collect image information of seeds and transmit it to the image processor for identifying fluorescent seeds.

[0045] The image processor is used to determine the seeds containing the fluorescence signal in the image information as the fluorescence seeds, and determine the seeds not containing the fluorescence signal as the common seeds.

[0046] In order to facilitate the recognition of the image processor, the background light in the image taken by the camera 303 needs to be removed, so a black light-shielding panel is attached to the fixed frame 301 to prevent external light from irradiating into the fixed frame 301 .

[0047] In one example of the present invention, there are two light sources 302 and two cameras 303, and the light sources 302 are fixed on both sides of the fixed frame 301 to illuminate the seeds at different angles. The two light sources 302 can illuminate the seeds from two opposite directions, increase the illumination coverage of the seeds, and better stimulate the fluorescence signal of the fluorescent seeds. The two cameras 303 are fixed side by side on the top of the fixed frame 301 at a preset angle, and the fluorescence signal stimulated by the fluorescent seeds is received by the two cameras 302 at a certain angle. The image processor recognizes the fluorescence signal based on the images taken by the two cameras 303, and can more accurately identify the fluorescent seeds.

[0048] Figure 7 The structure of the sorting mechanism provided by the embodiment of the present invention is shown.

[0049] like Figure 7As shown, the sorting mechanism includes a nozzle assembly 401, a first material trough 402, a second material trough 403, a sorting substrate 404 and a lifting assembly 405. The sorting substrate 404 is fixed above the conveyor belt 201 through an L-shaped adjustment frame 406. The L-shaped adjustment frame 406 includes a horizontal portion and a vertical portion. The horizontal portion is fixedly connected to both sides of 202, and a long strip adjustment hole is opened on the vertical portion. The lifting assembly 405 is locked on the long strip adjustment hole through a locking mechanism. By locking the lifting assembly 405 at different positions of the long strip adjustment hole, the height adjustment of the nozzle assembly 401 connected thereto can be achieved. The lifting assembly 405 is used to drive the nozzle assembly 401 to rise and fall, so that the nozzle assembly 401 can be close to the seeds on the conveyor belt 201 to ensure the absorption of the seeds.

[0050] The fluorescent seeds on the conveyor belt 201 are sucked into the first trough 402 through the suction nozzle assembly 401, and the remaining ordinary seeds on the conveyor belt 201 continue to be conveyed along the conveyor belt 201 until they fall into the second trough 403, thereby achieving the separation of ordinary seeds and fluorescent seeds.

[0051] In order to avoid the problem of fluorescent seeds being missed, the nozzle assemblies 401 are arranged in two rows staggered from each other so that the two rows of nozzle assemblies 401 form an overlapping area along the seed transmission direction. The seeds located in the non-overlapping area of ​​the two rows of nozzle assemblies 401 are sucked by driving the corresponding nozzle assemblies 401, while the seeds located in the overlapping area of ​​the two rows of nozzle assemblies 401 are driven to work simultaneously by the two nozzle assemblies 401 forming the overlapping area to suck the seeds in the corresponding overlapping area.

[0052] Figure 8 The overlapping area of ​​the nozzle assembly provided by the embodiment of the present invention is shown.

[0053] like Figure 8 As shown, the two suction nozzle assemblies in the first row and one suction nozzle assembly in the second row form overlapping areas, which are respectively recorded as area A and area B. The areas of area A and area B are larger than the area of ​​a seed. The area where the suction nozzle assembly in the second row does not overlap with the two suction nozzle assemblies in the first row is recorded as area C. When the fluorescent seed is located in area C, the control system controls the suction nozzle assembly directly opposite to the fluorescent seed to work and absorb the fluorescent seed; when the fluorescent seed is located in area A and area B, the control system controls the two suction nozzle assemblies corresponding to area A and area B to work simultaneously and absorb the fluorescent seeds in area A and area B.

[0054] The staggered arrangement of the two rows of nozzle assemblies can ensure that the fluorescent seeds will not be missed, and each nozzle assembly corresponds to a lifting assembly.

[0055] Fig. 9 The present invention provides a structure of a nozzle assembly and a lifting assembly.

[0056] like Fig. 9 As shown, the lifting assembly includes a cylinder 4051, a cylinder fixing plate 4052, a guide plate 4053 and a support rod 4054. The cylinder 4051 is fixed on the cylinder fixing plate 4052, and the top rod of the cylinder 4051 extends downward from the cylinder fixing plate 4052. The support rod 4054 is connected between the cylinder fixing plate 4052 and the guide plate 4053 to support and fix the cylinder fixing plate 4052. The guide plate 4053 is fixed on the sorting substrate 404.

[0057] The suction nozzle assembly includes a suction nozzle 4011, a wrapping belt 4012 and a pneumatic conveyor 4013. The suction nozzle 4011 is connected to the pneumatic conveyor 4013 and is used to suck the fluorescent seeds into the first material trough 402. The wrapping belt 4012 is two integrally formed clamps, which are respectively used to tighten the top rod of the cylinder 4051 and the pneumatic conveyor 4013. The pneumatic conveyor 4013 and the suction nozzle 4011 are driven to rise and fall synchronously through the extension and retraction of the top rod of the cylinder 4051, so that the suction nozzle 4011 is close to or away from the conveyor belt 201.

[0058] An avoidance hole is opened at a position of the sorting substrate 404 corresponding to the suction nozzle 4011 , so that the suction nozzle 4011 can pass through the sorting substrate 404 .

[0059] The guide plate 4053 has an arc surface that follows the shape of the pneumatic conveyor 4013 , and guides the pneumatic conveyor 4013 and indirectly guides the suction nozzle 4011 during the lifting and lowering process of the pneumatic conveyor 4013 .

[0060] The control system generates control instructions for sucking fluorescent seeds according to the speed of the conveyor belt mechanism and the image information of the seeds, controls the corresponding suction nozzle assembly and lifting assembly to move, and sucks the corresponding fluorescent seeds.

[0061] The speed of the conveyor belt mechanism is the speed of the seeds, and the image information of the seeds includes the lateral position of the seeds on the conveyor belt. The control system actually sends a delayed suction instruction to the designated suction nozzle assembly based on the speed and position of the seeds, thereby sucking the fluorescent seeds into the first trough.

[0062] The control system can control the speed of the conveyor belt. The speed data is the basic data for the control system to realize the delayed working time of the suction nozzle. The speed calibration of the conveyor belt is realized through the hole arrays on both sides of the conveyor belt.

[0063] The above content describes in detail the fluorescent seed sorting device provided by the present invention. The working process of the fluorescent seed sorting device is as follows:

[0064] First, start the conveyor belt, then start the light source. After the light source is stable, start the camera and collect the image information of the conveyor belt in real time and send it to the image processor. The image information includes two parts: one part is the hole array information of the conveyor belt (as feedback data of the conveyor belt position and speed), and the other part is the image information of the seed (for image analysis and judgment). The image processor determines whether it is a fluorescent seed based on the image information. The control system will combine the position and speed information of the fluorescent seed, as well as the fluorescent image information of the fluorescent seed to issue a delayed suction instruction to control the action of a certain suction nozzle component of the sorting mechanism. Under the control of the delayed suction instruction, the suction nozzle component first drives the suction nozzle to move downward to approach the fluorescent seed to be sucked through the cylinder assembly, and then the pneumatic conveyor is activated to suck the fluorescent seed from the conveyor belt into the first trough.
