Description

Technical Field

[0001] This utility model relates to the technical field of seed cotton processing equipment. Specifically, it is a seed cotton foreign fiber sorting device based on hyperspectral and visible light cameras, which is particularly suitable for automated feeding and seed cotton sorting operations in the seed cotton pretreatment process. Background Technology

[0002] During harvesting, storage, and transportation, seed cotton is highly susceptible to contamination with various foreign fibers and impurities, including chemical fibers, hair, plastic film, dyed threads, cotton leaves, and grass. The widespread use of mechanized harvesting and plastic film mulching has made plastic film the primary source of foreign fibers in seed cotton, further complicating purification processes. The presence of foreign fibers is a significant problem in seed cotton processing; therefore, achieving efficient separation of foreign fibers from seed cotton at the source is crucial for improving seed cotton quality and reducing industry costs.

[0003] Chinese invention patent CN117066160A discloses a well-sealed hyperspectral imaging sorting component for seed cotton sorting. Through its sealed and dustproof design, it ensures the hyperspectral camera is not contaminated by dust, and it also incorporates a multi-degree-of-freedom adjustment system to allow the camera to rotate freely and obtain comprehensive shooting angles. However, the patent has a drawback: it is ineffective at sorting small, colored impurities (such as leaves, hair strands, etc.) on the seed cotton that cannot be detected by the hyperspectral camera. This results in a large amount of such impurities remaining in the sorted seed cotton, failing to meet the production requirements for higher seed cotton purity and limiting the practical application of the component. Utility Model Content

[0004] This invention relates to a seed cotton foreign fiber sorting device based on a hyperspectral and visible light camera. It provides a seed cotton foreign fiber sorting device with a high degree of automation, good sorting effect, and strong environmental adaptability, in order to solve the problems of incomplete seed cotton sorting, low efficiency, and great influence from ambient light.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical means: Reference Figures 1-12 As can be seen, the seed cotton foreign fiber sorting device based on hyperspectral and visible light cameras of this utility model consists of a sorting and conveying chamber, a conveyor belt, a hyperspectral camera, a visible light camera, a blower seat, a cotton pulling box, a combination lamp tube, a sorting box, an electromagnetic air jet sorting component, and a control console.

[0006] An air-blowing sorting interval is provided between the conveyor belt and the cotton-pulling box. A flat cavity with openings at the top and bottom is connected to the air-blowing sorting interval. The two longer sides of the flat cavity are close to the conveyor belt and the cotton-pulling box, respectively. The top opening of the sorting and conveying cavity is slightly lower than the discharge end of the conveyor belt. A blow-selection station is provided at the end of the conveyor belt. A hyperspectral camera is connected above the blow-selection station and the hyperspectral camera is equipped with a hyperspectral camera to take pictures of the seed cotton conveyed by the conveyor belt. An electromagnetic air jet sorting component is connected above the sorting and conveying chamber of the blow-selection station. The electromagnetic air jet sorting component is controlled to blow air into the sorting and conveying chamber below. The cotton pulling box is provided with a feed inlet on the side near the sorting and conveying chamber. A pair of oppositely rotating licker rollers are fixed in the cotton pulling box. The seed cotton input through the feed inlet is opened by the rotation of the licker rollers and clamped and conveyed to the sorting box below. The sorting box is equipped with a vertically arranged glass channel. The top opening of the glass channel receives the seed cotton after it has been opened by the licker roller. The bottom opening of the glass channel has two openings: one corresponding to the top opening is the clean seed cotton outlet, and the other opening is located on the side wall at the bottom of the glass channel, sloping outward and downward, and is the seed cotton containing impurities outlet, used for discharging seed cotton containing fine and colored impurities. On the opposite side wall of the seed cotton containing impurities outlet, an electromagnetic air jet sorting component two is provided. The electromagnetic air jet sorting component two is controlled to blow air into the seed cotton containing impurities outlet. The two visible light cameras are fixedly connected to the outer sides of the glass channel respectively. The two visible light cameras have the same structure. Each visible light camera is equipped with a common camera to capture images of the cotton falling inside the glass channel. The combined light tubes are installed on both sides of the outer side of the glass passage; The control console is electrically connected to a hyperspectral camera, a visible light camera, an electromagnetic air-jet sorting component one, and an electromagnetic air-jet sorting component two. The control console controls the hyperspectral camera and the visible light camera to transmit images to the control console. Based on the images, the control console controls the electromagnetic air-jet sorting component one and the electromagnetic air-jet sorting component two to blow the cotton containing impurities toward the sorting and conveying chamber or the cotton seed discharge port containing impurities.

[0007] The sorting and conveying chamber is an arc-shaped chamber. The arc shape of the chamber helps prevent materials from falling directly downwards from the top opening when air is not being blown.

[0008] The conveyor belt is used for transporting seed cotton. The strip connection is set on two spaced rollers; the motor drives one of the rollers to rotate, which in turn drives the strip belt to transport the seed cotton to the sorting conveyor chamber for the first sorting. The motor drives the belt to rotate and transport materials toward the sorting and conveying chamber.

[0009] The hyperspectral camera includes a hyperspectral camera, a yaw brushless motor, and a pitch brushless motor. The yaw brushless motor drives the pitch brushless motor to rotate horizontally, and the pitch brushless motor drives the hyperspectral camera to rotate vertically.

[0010] Impurities on the seed cotton that are similar to the seed cotton (such as transparent mulch film, white paper pieces, thread ends, etc.) are identified by taking pictures using a hyperspectral camera.

[0011] The electrical control box receives control commands sent by the operator via remote control and sends control commands to the yaw brushless motor and the pitch brushless motor to control the rotation angle, speed and direction of the yaw brushless motor and the pitch brushless motor.

[0012] The visible light camera is fixedly connected inside the sorting box. The visible light camera is equipped with a regular camera, a second yaw brushless motor, a second pitch brushless motor, and a second electrical control box. The second yaw brushless motor drives the second pitch brushless motor to rotate in the horizontal direction. The second yaw brushless motor and the second pitch brushless motor control the direction of the regular camera. The second electrical control box sends precise control commands to the second yaw brushless motor and the second pitch brushless motor.

[0013] Tiny, colored impurities on the seed cotton (such as leaves, hairs, etc.) are identified by taking pictures with a regular camera.

[0014] The second control box sends precise control commands to the second yaw brushless motor and the second pitch brushless motor to control the rotation angle, speed and direction of the motors, coordinate the operation between the yaw brushless motor and the pitch brushless motor, so that the gimbal can move according to the preset mode and path, and receive various commands sent by the operator through the remote control.

[0015] The blowing and separating station is a shell structure with two vertical plates and a top plate. The bottom ends of the two vertical plates are connected to the two sides of the conveyor belt frame, so that the blowing and separating station straddles the conveyor belt. The top ends of the two vertical plates are connected to the top plate, and a hyperspectral camera is connected to the top plate.

[0016] The cotton-pulling box 6 is also equipped with an unclean seed cotton storage box; the opening of the unclean seed cotton storage box is located below the sorting and conveying chamber to receive the impure seed cotton output from the sorting and conveying chamber.

[0017] The combined lamp tube is equipped with a lamp holder and a UVC lamp tube (702); the UVC lamp tube (702) is placed on the lamp holder, and the lamp holder is connected to both sides of the outside of the glass channel.

[0018] The combined light tubes are spaced vertically to provide ample illumination.

[0019] The working principle and process of this utility model are as follows: The seed cotton to be sorted is placed on a conveyor belt and transported to the feed inlet of the cotton removal box. The control console controls the hyperspectral camera on the blowing seat to photograph and identify impurities similar to the seed cotton (such as transparent mulch, white paper, thread ends, etc.). Based on the identification results, the control console controls the electromagnetic air jet sorting component one to spray the unclean seed cotton into the unclean seed cotton collection box of the cotton removal box. Seed cotton not identified by the hyperspectral camera enters the cotton removal box through the feed inlet. The licker roller opens the cotton and pulls the seed cotton down to the glass channel. The control console controls the visible light camera and the electromagnetic air jet sorting component two in the sorting box to perform secondary sorting of the seed cotton. Finally, the unclean seed cotton flows out through the inclined outlet of the glass channel, and the clean seed cotton flows out through the vertical outlet.

[0020] The advantages of this utility model are: (1) Equipped with a hyperspectral camera and a visible light camera, it has multi-degree-of-freedom adjustment capabilities, enabling dynamic tracking and identification of impurities in seed cotton without blind spots and from multiple angles.

[0021] (2) The electromagnetic air-jet sorting component 1 and electromagnetic air-jet sorting component 2 are controlled by the control console to perform two sorting operations on the identified impurity seed cotton based on the identification results. The two sorting modes are as follows: the hyperspectral camera at the blower seat and electromagnetic air-jet sorting component 1 perform preliminary sorting to remove seed cotton containing impurities similar to seed cotton (such as transparent mulch film, white paper, thread ends, etc.); the visible light camera in the sorting box and electromagnetic air-jet sorting component 2 perform secondary identification and sorting to remove seed cotton containing small, colored impurities (such as leaves, hair strands, etc.) and to sort out clean seed cotton. This dual sorting mode greatly improves the purity of seed cotton and has a high sorting accuracy.

[0022] (3) The seed cotton is opened by the licking roller and pulled downward so that the seed cotton does not stick together, which facilitates the identification of the visible light camera. Attached Figure Description

[0036] The present invention will be further described below with reference to the embodiments.

[0037] Reference Figures 1-12 It is understood that the seed cotton foreign fiber sorting device based on hyperspectral and visible light cameras of this utility model consists of a sorting and conveying chamber 1, a conveyor belt 2, a hyperspectral camera 3, a visible light camera 4, a blower seat 5, a cotton pulling box 6, a combination lamp tube 7, a sorting box 8, an electromagnetic air jet sorting component 2 9, and a control console 10.

[0038] An air-blowing sorting interval is provided between the conveyor belt 2 and the cotton-pulling box 6. A sorting and conveying chamber 1 with a flat cavity that is open at the top and bottom is connected to the air-blowing sorting interval. The two longer sides of the flat cavity are close to the conveyor belt 2 and the cotton-pulling box 6 respectively. The top opening of the sorting and conveying chamber 1 is slightly lower than the discharge end of the conveyor belt 2. At the end of the conveyor belt 2, a blow-selection seat 5 is provided. A hyperspectral camera 3 is connected above the conveyor belt to the blow-selection seat 5. The hyperspectral camera 3 is equipped with a hyperspectral camera 301 to take pictures of the seed cotton conveyed by the conveyor belt 2. An electromagnetic jet sorting component 501 is connected above the sorting and conveying chamber 1 to the blow-selection seat 5. The electromagnetic jet sorting component 501 is controlled to blow air into the sorting and conveying chamber 1 below. The cotton pulling box 6 is provided with a feed inlet 602 on the side near the sorting and conveying chamber 1. A pair of oppositely rotating licker rollers 603 are fixed in the cotton pulling box 6. The seed cotton input into the feed inlet 602 is opened by the rotation of the licker rollers 603 and the seed cotton is clamped and conveyed to the sorting box 8 below. The sorting box 8 is provided with a vertically arranged glass channel 801. The top opening of the glass channel 801 receives seed cotton after it has been opened by the needle roller 603. The bottom opening of the glass channel 801 has two openings. One opening corresponds to the top opening and is the clean seed cotton outlet. The other opening is located on the side wall at the bottom of the glass channel 801 and is inclined outward and downward. It is the seed cotton outlet containing impurities and is used to discharge seed cotton containing fine and colored impurities. An electromagnetic air jet sorting component 2 9 is provided on the side wall corresponding to the impurity seed cotton outlet. The electromagnetic air jet sorting component 2 9 is controlled to blow air into the impurity seed cotton outlet. Two visible light cameras 4 are fixedly connected to the outer sides of the glass channel 801 respectively. The two visible light cameras 4 have the same structure. Each visible light camera 4 is equipped with a common camera 401 to capture images of cotton falling inside the glass channel 801. The combined lamp tubes 7 are arranged on both sides of the outer side of the glass channel 801; The control console 10 is electrically connected to the hyperspectral camera 3, the visible light camera 4, the electromagnetic air jet sorting component 501, and the electromagnetic air jet sorting component 9. The control console 10 controls the hyperspectral camera 3 and the visible light camera 4 to transmit images to the control console 10. The control console 10 controls the electromagnetic air jet sorting component 501 and the electromagnetic air jet sorting component 9 to spray air, respectively blowing cotton containing impurities towards the sorting and conveying chamber 1 or the cotton seed discharge port containing impurities.

[0039] The sorting and conveying chamber 1 is a flat cavity, and the two longer sides of the flat cavity are close to the conveyor belt 2 and the cotton pulling box 6 respectively. The top opening of the sorting and conveying chamber 1 is slightly lower than the discharge end of the conveyor belt 2. Therefore, if the cotton is free of impurities, the seed cotton will be transported by the conveyor belt 2 and, due to inertia, will cross the sorting and conveying chamber 1 and enter the cotton pulling box 6.

[0040] The sorting and conveying chamber 1 is an arc-shaped chamber. The arc shape of the chamber helps to prevent materials from falling directly downwards from the top opening when air is not being blown.

[0041] Both the electromagnetic jet sorting component 1 (501) and the electromagnetic jet sorting component 2 (9) have jet pipes arranged at intervals, and the jet pipes are equipped with solenoid valves to control the jet action.

[0042] Conveyor belt 2 is used for transporting seed cotton. Strip belt 203 is connected to two spaced rollers 202; motor 201 drives one of the rollers 202 to rotate, thereby driving strip belt 203 to rotate, transporting seed cotton to sorting conveyor chamber 1 for the first sorting; Motor 201 drives belt 203 to rotate and transport materials in the sorting and conveying chamber 1.

[0043] See Figure 5 It is known that the hyperspectral camera 3 is equipped with a hyperspectral camera 301, a yaw brushless motor 302, and a pitch brushless motor 303. The yaw brushless motor 302 drives the pitch brushless motor 303 to rotate in the horizontal direction, and the pitch brushless motor 303 drives the hyperspectral camera 301 to rotate in the vertical direction.

[0044] Impurities similar to seed cotton, such as transparent mulch film, white paper scraps, and loose threads, are identified by taking pictures using a hyperspectral camera 301.

[0045] The electrical control box 304 receives control commands sent by the operator via remote control and sends control commands to the yaw brushless motor 302 and the pitch brushless motor 303 to control the rotation angle, speed and direction of the yaw brushless motor 302 and the pitch brushless motor 303.

[0046] See Figure 6 It is known that the visible light camera 4 is fixedly connected inside the sorting box 8. The visible light camera 4 is equipped with a regular camera 401, a second yaw brushless motor 402, a second pitch brushless motor 403, and a second electrical control box 404. The second yaw brushless motor 402 drives the second pitch brushless motor 403 to rotate in the horizontal direction. The second yaw brushless motor 402 and the second pitch brushless motor 403 control the direction of the regular camera 401. The second electrical control box 404 sends precise control commands to the second yaw brushless motor 402 and the second pitch brushless motor 403.

[0047] Small, colored impurities on the seed cotton, such as leaves and hairs, are identified by taking pictures using a standard 401 camera.

[0048] The control box 404 sends precise control commands to the yaw brushless motor 402 and the pitch brushless motor 403 to control the rotation angle, speed and direction of the motors, coordinate the operation between the yaw brushless motor and the pitch brushless motor, and enable the gimbal to move according to the preset pattern and path. It also receives various commands sent by the operator through the remote control.

[0049] The blowing and separating seat 5 is a shell structure, which has two vertical plates and a top plate. The bottom ends of the two vertical plates are connected to the two sides of the frame of the conveyor belt 2 respectively, so that the blowing and separating seat 5 straddles the conveyor belt 2. The top ends of the two vertical plates are connected to the top plate, and the hyperspectral camera 3 is connected to the top plate.

[0050] The cotton-pulling box 6 is also provided with an unclean seed cotton storage box 601; the opening of the unclean seed cotton storage box 601 is located below the sorting and conveying chamber 1 to receive the impure seed cotton output from the sorting and conveying chamber 1.

[0051] See Figure 3 , Figure 11 The combined lamp tube 7 is provided with a lamp holder 701 and a UVC lamp tube 702; the UVC lamp tube 702 is placed on the lamp holder 701, and the lamp holder 701 is connected to both sides of the outside of the glass channel 801.

[0052] The combination lamps 7 are arranged at vertical intervals to provide ample illumination.

[0053] The working principle and process of this utility model are as follows: The seed cotton to be sorted is placed on conveyor belt 2 and transported to the feed inlet 602 of cotton removal box 6. Control console 10 controls the hyperspectral camera 3 on the blowing seat 5 to photograph and identify impurities similar to the seed cotton, such as transparent mulch, white paper, and thread ends. According to the identification results, control console 10 controls the electromagnetic air jet sorting component 501 to spray the unclean seed cotton into the unclean seed cotton collection box 601 of cotton removal box 6. Seed cotton not identified by hyperspectral camera 3 enters cotton removal box 6 through feed inlet 602. The licker roller 603 opens and pulls the seed cotton down to glass channel 801. Control console 10 controls the visible light camera 4 and electromagnetic air jet sorting component 9 in sorting box 8 to perform secondary sorting of seed cotton. Finally, unclean seed cotton flows out through the inclined outlet of glass channel 801, and clean seed cotton flows out through the vertical outlet.

[0054] The advantages of this embodiment are: First: It is equipped with a hyperspectral camera 3 and a visible light camera 4, which have multi-degree-of-freedom adjustment capabilities, enabling dynamic tracking and identification of impurities in seed cotton without blind spots and from multiple angles.

[0055] Second: Based on the identification results, the control console 10 controls the electromagnetic air-jet sorting components 501 and 9 to perform two sorting processes on the identified impurity seed cotton. The two sorting modes are as follows: First, the hyperspectral camera 3 at the blower seat 5 and the electromagnetic air-jet sorting component 501 perform initial sorting, removing seed cotton containing impurities similar to seed cotton, such as transparent mulch film, white paper scraps, and thread ends. Second, the visible light camera 4 in the sorting box 8 and the electromagnetic air-jet sorting component 9 perform secondary identification and sorting, removing seed cotton containing small, colored impurities such as leaves and hair strands, and separating clean seed cotton. This dual sorting mode greatly improves the purity of the seed cotton and achieves high sorting accuracy.

[0056] Third: The seed cotton is opened by the 603 licker-in roller and pulled downwards, so that the seed cotton does not stick together, which facilitates the identification of the visible light camera.
