Abstract
Description
Technical Field
[0001] The present application relates to the technical field of automated plant seed sorting, and in particular to sorting equipment. Background Art
[0002] With the development of economy, the production and circulation of seeds are increasing. Seed sorting is an important link to ensure the quality of seeds and promote the process of seed industrialization. In the process of modern corn seed breeding, the use of haploid technology to obtain pure lines and then select inbred lines can speed up the breeding process and improve the breeding efficiency. Rapid and non-destructive identification of haploid grains from polyploid grains has become the key to haploid breeding technology.
[0003] At present, corn haploid sorting relies on manual identification and sorting, and the sorting efficiency is very low, which is not suitable for large-scale production and planting. Some existing sorting systems use image processing systems to calculate the time when the current position of the seed reaches the sorting module, and then use high-pressure gas sources to directly act on the seeds to achieve the classification needs of different seeds. The above sorting scheme has high requirements on the position of the seeds on the conveying mechanism, and there can be no movement in the middle; and the seeds are sorted by directly acting on the seeds with high-pressure gas. If the seeds move on the conveying mechanism, it will affect the accuracy of the final sorted seeds, and the appearance, falling state, and air pressure stability of the seeds are required to be high. Especially for corn seeds with irregular shapes, the actual blowing required for each seed is quite different, which will lead to a low sorting accuracy. Summary of the invention

[0050] See also Figure 1 and Figure 2 , Figure 1 The schematic diagram of the structure of the sorting device according to one embodiment of the present application is shown. Figure 2 The schematic diagram of the structure of the sorting connection component in the sorting device of one embodiment of the present application is shown. At least one embodiment of the present application proposes a sorting device, including a sorting chute 2, a sorting channel 3 and a sorting connection component 4, the sorting chute 2 is provided with an inlet end 21 and an outlet end 22, the outlet end 22 extends downwardly and tilted, so that the seeds to be sorted enter the sorting chute 2 through the inlet end 21 and slide toward the outlet end 22, each sorting chute 2 is provided with a sorting port 23, the sorting port 23 is connected to the sorting channel 3, and the sorting port 23 is correspondingly provided with a sorting connection component 4, and the sorting connection component 4 is used to open or close the sorting port 23 to control the seeds to be sorted to enter the sorting channel 3 from the sorting port 23 or continue to slide down along the sorting chute 2 when passing through the sorting port 23.
[0051] According to the sorting device of the embodiment of the present application, the seeds to be sorted enter the sorting chute 2 from the inlet end 21, and the sorting connection component 4 controls the opening or closing of different sorting ports 23 on each sorting chute 2, so that the seeds enter the sorting channel 3 through the corresponding sorting ports 23. The above-mentioned sorting device has low requirements on the position of the incoming seeds, and the seeds that move in the middle can also smoothly enter the sorting chute 2 from the inlet end 21, and the corresponding sorting ports 23 are opened or closed by the sorting connection component 4 to control the seeds to be sorted to enter the sorting channel 3 through the corresponding sorting ports 23, so as to achieve the effect of improving the sorting accuracy.
[0052] See 1 and Figure 3 In some embodiments, the sorting device further includes a channel guide component 1, which is connected to the inlet end 21 of the sorting slide 2 and is used to adjust the posture of the seeds to be sorted entering the sorting slide 2. As a result, the sorting device has low requirements on the position of the seeds to be sorted, and the seeds that move in the middle, whether they are slightly swung or turned, will be adjusted by the channel guide component 1, so that the seeds to be sorted can enter the sorting slide 2 more smoothly, and then enter the sorting channel 3 through the corresponding sorting port 23, further improving the effect of sorting accuracy.
[0053] Specifically, in some embodiments, the seeds to be sorted are usually conveyed by the conveyor belt 11, and the conveyor belt 11 moves to drive the seeds to be sorted placed on the upper surface of the conveyor belt 11 to move to the channel guide assembly 1. The channel guide assembly 1 includes a guide plate 12 arranged on the upper surface of the conveyor belt 11, and the guide plate 12 is provided with a plurality of guide grooves 121 on one side of the upper surface of the conveyor belt 11. The guide grooves 121 and the upper surface of the conveyor belt 11 are enclosed to form guide channels 122. The number of guide channels 122 is the same as the number of sorting chutes 2, and each guide channel 122 is correspondingly connected to the inlet end 21 of a sorting chute 2, so that the incoming seeds can enter the inlet end 21 of the sorting chute 2 after passing through the guide channel 122 under the conveying action of the conveyor belt 11.
[0054] See also Figure 1 In some embodiments, the sorting device includes seven sorting slides 2, and each sorting slide is provided with two sorting ports 23. The channel guide assembly 1 can guide the incoming seeds into the seven sorting slides 2, respectively, and then sort them in each sorting slide 2. It is understandable that the user can design and select different numbers of sorting slides 2 and sorting ports 23 according to the sorting conditions of specific seeds, so as to adjust the throughput and sorting categories.
[0055] In some embodiments, the inner wall of the inlet end 21 of the sorting chute 2 is inclined and V-shaped, which has a guiding effect on the seeds entering the sorting chute 2 .
[0056] See also Figure 1 and Figure 2 , Figure 2 The structural schematic diagram of the sorting connection component 4 in the sorting device of one embodiment of the present application is shown. In some embodiments, the sorting connection component 4 includes a sorting partition 41 and a sorting drive 42, the sorting partition 41 is used to close the sorting port 23, and the sorting drive 42 is connected between the sorting slide 2 and the sorting partition 41, and is used to drive the sorting partition 41 to be placed in the sorting port 23 or outside the sorting port 23 to open or close the sorting port 23.
[0057] Specifically, the sorting port 23 is opened with the bottom wall of the sorting chute 2 and penetrates the bottom wall of the sorting chute 2. When the sorting partition 41 is placed in the sorting port 23 and the sorting port 23 is closed, the surface of the sorting partition 41 is flush with the inner wall surface of the sorting chute 2. When the seeds slide down to the surface of the sorting partition 41, they can smoothly pass through the surface of the sorting partition 41 and continue to slide down, avoiding the jamming of the seeds, ensuring the smooth movement of the seeds in the sorting chute 2, and improving the sorting efficiency.
[0058] Through the above arrangement, when the sorting partition 41 is placed in the sorting port 23, the sorting partition 41 closes the sorting port 23; when the sorting partition 41 is placed outside the sorting port 23, the sorting partition 41 opens the sorting port 23, and the sorting drive 42 can drive the sorting partition 41 to move, switching between being placed in the sorting port 23 and being placed outside the sorting port to open or close the sorting port 23. It can be understood that in some embodiments, when the sorting partition 41 opens the sorting port 23, the sorting partition 41 is lifted and placed inside the sorting slide 2, which can prevent the sorting partition 41 from occupying the path of the seeds moving from the opened sorting port 23 to the sorting channel 3, making the seed sorting smoother.
[0059] In some embodiments, the sorting driving member 42 is configured as a driving cylinder, which is installed on the outer wall of the sorting slide 2 , and the output end of the driving cylinder is fixedly connected to the sorting partition 41 .
[0060] Specifically, the driving cylinder is arranged in a direction perpendicular to the length direction of the sorting chute 2. The driving cylinder is connected with a mounting plate 421, which is fixed to the bottom outer wall of the sorting chute 2 by bolts. The output end of the driving cylinder faces the end away from the sorting chute 2, and is fixedly connected to the sorting partition 41 through a connecting plate 422, and the connecting plate 422 is L-shaped. One end of the connecting plate 422 is fixedly connected to the bottom of the output end of the driving cylinder, and the other end is fixedly connected to the bottom of the sorting partition 41. A reinforcing plate 4221 is fixed between the side wall of the connecting plate 422 and the side wall of the sorting partition 41 to improve the structural stability of the sorting partition 41.
[0061] See also Figure 3 , Figure 3 A cross-sectional view of a sorting device according to an embodiment of the present application is shown. When the output end of the driving cylinder is extended, the sorting baffle 41 is driven to move into the sorting port 23, closing the sorting port 23. When the seeds pass through the sorting port 23, they will continue to slide down along the sorting chute 2; when the output end of the driving cylinder is shortened, the sorting baffle 41 is driven to move outside the sorting port 23 and placed in the sorting chute 2. The sorting port 23 is opened, and the seeds can fall into the sorting channel 3 connected to the sorting port 23 through the sorting port 23.
[0062] See also Figure 4 , Figure 4 for Figure 3 A partial enlarged schematic diagram of point A in the middle. In order to improve the movement stability of the sorting baffle 41, so that the sorting baffle 41 can open or close the sorting port 23 accurately and smoothly each time, a moving stabilizing component is provided between the connecting plate 422 and the mounting plate 421. The moving stabilizing component can limit the movement trajectory of the sorting baffle 41 when the driving cylinder drives the sorting baffle 41 to move.
[0063] Specifically, in some embodiments, the mobile stabilizing assembly includes a stabilizing bolt 4211 fixedly mounted on the mounting plate 421, and a stabilizing slide groove 4222 for the stabilizing bolt 4211 to slide is provided on the connecting plate 422. When the output end of the driving cylinder is extended or retracted, the connecting plate 422 is driven to move, the stabilizing bolt 4211 is fixed, and the stabilizing slide groove 4222 slides relative to the stabilizing bolt 4211. Furthermore, when the telescopic end of the driving cylinder is extended or retracted, the connecting plate 422 and the mounting plate 421 are always in contact and can slide relative to each other, which also has a certain stabilizing effect, further improving the mobile stability of the sorting partition 41, so that the sorting partition 41 can open or close the sorting port 23 accurately and smoothly every time.
[0064] In some other embodiments, the sorting drive 42 can also be configured as a motor or an electromagnet. When the sorting drive 42 is configured as a motor, the motor is connected to a gear rack structure, a lead screw guide structure or a cam connecting rod structure to drive the sorting baffle 41 to move in a straight line to open or close the sorting port 23. The sorting drive 42 can also be configured as an electromagnet, and the sorting baffle 41 is configured to move in response to the magnetic attraction of the electromagnet. By energizing or de-energizing the electromagnet, the sorting baffle 41 is driven to complete a linear reciprocating motion to open or close the sorting port 23.
[0065] In some embodiments, the sorting device also includes a control component 6 for receiving type information of seeds to be sorted; and the control component 6 is communicatively connected to the sorting connection component 4, for controlling the sorting connection component 4 to open the corresponding sorting port according to the type information of the seeds to be sorted, so that seeds of a preset type enter the sorting channel 3 through the corresponding sorting port 23.
[0066] Specifically, the seed type information can be determined by the color, shape and / or texture of the seeds based on visual image recognition technology; it can also be determined by the moisture content, starch content and / or fatty acid content of the seeds based on near-infrared spectroscopy technology; it can also be determined by the moisture content and / or oil content of the seeds based on nuclear magnetic resonance spectroscopy.
[0067] It can be understood that the above-mentioned seed type determination methods can be used independently or in combination to accurately determine the type information of the seeds to be sorted; and, the above-mentioned seed type determination can be carried out before the seeds to be sorted enter the sorting device, when they enter the sorting device, or after they enter the sorting device, and at the same time, it should be satisfied that before the seeds of the preset type arrive at the corresponding sorting port 23, the control component 6 receives the type information of the seeds to be sorted, and controls the sorting connection component 4 to open the corresponding sorting port, so that the seeds of the preset type can enter the sorting channel 3 through the corresponding sorting port 23.
[0068] See also Figure 5 , Figure 5 A simplified schematic diagram of an image acquisition component 5 and a control component 6 in a sorting device according to an embodiment of the present application is shown. In some embodiments, the sorting device further includes an identification component, which is used to identify the type of seeds to be sorted before the seeds to be sorted arrive at the sorting port 23, and send the type information of the seeds to be sorted to the control component 6.
[0069] Specifically, in some embodiments, the recognition component is configured as an image acquisition component 5, and the image acquisition component 5 can replace different light sources and cameras, such as light sources and cameras that can shoot fluorescence, near-infrared spectrum light sources and cameras, etc., to adapt to classification tasks based on fluorescence, oil content, etc. By replacing the high-definition camera and the uniform light source in the image acquisition component 5 with a fluorescence / near-infrared spectrum camera with a filter, and a fluorescence / near-infrared light source with a specific wavelength range, it is possible to obtain information such as the fluorescence / near-infrared light intensity, fluorescence / near-infrared light distribution, and shape of the seeds on the conveyor belt 11 to determine the seed type information, and at the same time transmit the seed type information to the control component 6, and transmit the corresponding classification information to the sorting connection component 4, and finally achieve seed classification.
[0070] In some embodiments, the sorting device further includes an entrance detection component 7, which is disposed at the entrance end 21 and is used to detect a position signal of the seed at the entrance end 21. The entrance detection component 7 is in communication with the control component 6, and the entrance detection component 7 transmits the position signal to the control component 6, and the control component 6 controls the start time of the sorting connection component 4 to open the sorting port 23 according to the position signal. Through the above arrangement, the entrance detection component 7 can detect the seed that has just reached the entrance end 21 of the sorting chute 2, and set the start time of the sorting connection component 4 to open the sorting port 23 according to the time when the seed reaches the entrance position.
[0071] See also Figure 1 and Figure 3 In some embodiments, the entrance detection component 7 includes a through-beam photoelectric sensor 72 disposed at the entrance end 21. Specifically, the entrance detection component 7 includes a fixed plate 71, which is fixedly connected to the guide plate 12 of the channel guide component 1, and the through-beam photoelectric sensor 72 is installed on the fixed plate 71 and extends to the entrance end 21. When a seed passes through the through-beam photoelectric sensor 72, the through-beam photoelectric sensor 72 is triggered. After receiving the type information of the seed to be sorted, the control component 6 gives a signal for the corresponding sorting port 23 to be opened. By giving each seed a time interval for reaching the corresponding sorting port 23 from the entrance detection component 7, as long as the seed arrives within this time interval, the correct screening of the seed can be achieved.
[0072] In some embodiments, the start time is set to be a preset time interval after the moment when the seed reaches the entrance end 21. Since the seed has not reached the entrance end 21 of the sorting chute 2 when the identification component is classifying the seed, the seed also needs to slide down for a certain time after reaching the entrance end 21 of the sorting chute 2 to reach the corresponding sorting port 23. As long as the sorting port 23 is opened within the corresponding time, that is, before the seed reaches the corresponding sorting port 23, the seed can fall into the sorting channel 3 from the sorting port 23. The sorting channel 3 can have a certain redundancy for the time when the sorting port 23 is opened and closed. After the sorting port 23 is opened, it can remain open for a certain time, and the seed can enter the sorting port 23 within the opening time range, which can improve the classification accuracy. The farther the sorting port 23 is from the entrance detection component 7, the longer the spacing between the sorting ports 23, and the larger the spacing between adjacent seeds, the more redundant time, the higher the fault tolerance rate, and the seeds with irregular shapes and large differences in sliding speed can also ensure the classification accuracy.
[0073] In some embodiments, the control component 6 receives type information of seeds to be sorted, including a first target type and a second target type. Accordingly, a sorting port 23 is provided on each sorting chute 2 .
[0074] When the seeds to be sorted are identified as the first target type, the sorting port 23 is opened, and the seeds identified as the first target type fall into the sorting port 23; when the seeds to be sorted are identified as the second target type, the sorting port 23 is closed, and the seeds identified as the second target type pass through the sorting port 23 and slide to the exit end of the sorting slide 2. Of course, the type of seeds entering the sorting port 23 can be set according to the predicted ratio of the first target type seeds to the second target type seeds in the seeds to be sorted, so as to improve the sorting efficiency.
[0075] In some embodiments, the control component 6 receives type information of seeds to be sorted, including a first target type, a second target type, and a third target type. A first sorting port 231 and a second sorting port 232 are sequentially arranged on each sorting chute 2 along the direction of the seeds to be sorted. When the seeds to be sorted are identified as the first target type, the first sorting port 231 is opened, and the seeds identified as the first target type fall into the first sorting port 231; when the seeds to be sorted are identified as the second target type, the first sorting port 231 is closed, and the second sorting port 232 is opened, and the seeds identified as the second target type fall into the second sorting port 232 after passing through the first sorting port 231; when the seeds to be sorted are identified as the third target type, the first sorting port 231 is closed, and the second sorting port 232 is closed, and the seeds identified as the third target type slide to the outlet end 22 of the sorting chute 2 after passing through the first sorting port 231 and the second sorting port 232 respectively.
[0076] It can be understood that, in some embodiments, the first target type is configured as haploid grains, the second target type is configured as non-haploid grains, and the third target type is configured as unidentified grains. Among them, when the seeds to be sorted are identified as haploid grains, the first sorting port 231 is opened, the second sorting port 232 is closed, and the seeds identified as haploid grains fall into the first sorting port 231; when the seeds to be sorted are identified as non-haploid grains, the first sorting port 231 is closed, the second sorting port 232 is opened, and the seeds identified as non-haploid grains fall into the second sorting port 23; when the seeds to be sorted are identified as unidentified grains, the first sorting port 231 is closed, the second sorting port 232 is closed, and the seeds identified as unidentified grains slide to the outlet end 22 of the sorting slide 2 after passing through the first sorting port 231 and the second sorting port 232 respectively.
[0077] In some embodiments, the process of the recognition component and the control component identifying seeds and completing the sorting is roughly as follows: identifying whether there are seeds in the image and counting the number of seeds; calculating the position information of each seed; calculating the time taken for each seed to reach the corresponding sorting port 23; judging the category of each seed; transmitting the category, position, and time information of the seed to the sorting connection component 4; the sorting connection component 4 performs the action to complete the seed screening. It can be understood that in order to improve the recognition accuracy of the recognition component, the seeds can be arranged first. If seven sorting slideways 2 are provided in the embodiment, the seeds can also be arrayed in the form of 7×N.
[0078] Specifically, when the information of the seeds to be sorted is transmitted to the control component 6,
[0079] 1. The control component 6 first discriminates the seeds in the 7×n array in the picture, identifies the seeds in the picture from the background (the conveyor belt 11) and counts the number of seeds;
[0080] 2. Segment and crop each seed in the image along its outline, and calculate and record the coordinate information of the center position of the seed in the image;
[0081] 3. Calculate and record the time it takes for each seed to move along the conveyor belt 11 to the inlet end 21 of the sorting chute 2;
[0082] 4. Identify the color, posture, shape and other physical information of the seeds in the image to identify each seed category (haploid / non-haploid);
[0083] 5. The position information, time information and category information of the seed are transmitted to the sorting connection component 4, wherein the position information is the number of sorting chute 2 the seed falls into; the time information is when the seed reaches the entrance end 21 of the sorting chute 2; and the category information is whether the seed is classified as haploid or non-haploid;
[0084] 6. The sorting connection component 4 performs sorting actions on each seed according to the information transmitted by the control component 6.
[0085] See also Figure 6 , Figure 6 A cross-sectional view of the re-screening component 8 embodied in the sorting device of one embodiment of the present application is shown. In some embodiments, the sorting device further includes a re-screening component 8, which connects the outlet end 22 and the inlet end 21 of the sorting chute 2, and is used to transport the seeds of the third target type that slide down to the outlet end 22 to the inlet end 21 of the sorting chute 2, so as to re-sort the seeds of the third target type. The seeds identified as the third target type will not trigger the start of the sorting connection component 4, that is, the sorting port 23 will not be opened, and the closed sorting port 23 allows the seeds to slide directly down to the outlet end 22 in the sorting chute 2. Through the above arrangement, the re-screening component 8 can transport the seeds identified as the third target type at the outlet end 22 to the inlet end 21 of the sorting chute 2, and be re-identified by the identification component, so as to be re-sorted, thereby improving the classification efficiency and classification accuracy of the seeds.
[0086] Specifically, in some embodiments, the re-screening component 8 includes a pneumatic conveyor 81 and a re-screening channel 82. The re-screening channel 82 is connected to the outlet end 22 of the sorting chute 2 and is connected to the pneumatic conveyor 81. Driven by the pneumatic conveyor 81, the re-screening channel 82 transports the seeds identified as the third target type that slide down to the outlet end 22 to the inlet end 21 of the sorting chute 2, and is re-identified by the identification component for re-sorting.
[0087] The sorting equipment provided in the embodiment of the present application adopts a mechanical mechanism to realize the sorting of seeds of different categories, and can accommodate slight swinging and flipping of seeds on the conveying mechanism; it can realize the classification of multiple different categories of seeds at the same time, and more types of sorting can be realized by increasing the number of channels.
