Description

Technical Field

[0001] The invention relates to the technical field of agricultural machinery, in particular to a multifunctional corn tasseling detection device. Background Art

[0002] Corn is one of the most important food crops in the world and is widely planted on all continents around the world. The growth process of corn is divided into multiple stages, including the sowing period, seedling stage, ear stage and flowering and grain stage. The tasking occurs in the transition period from the ear stage to the flowering and grain stage. When corn enters the tasking stage, it marks the beginning of its transition from vegetative growth to reproductive growth.

[0003] At present, when the existing equipment is used under direct strong light or uneven lighting (for example, the light intensity at different positions is different due to the different heights of corn plants), the image obtained by the camera of the detection equipment may be overexposed or the details of the shadow part may be lost, making it difficult to accurately identify the color and texture characteristics of the corn tassel, thereby affecting the judgment of the tassel extraction state; the working range of the leaf stripping device is usually designed according to a certain standard corn plant height. When the actual plant height does not meet the design expectations, problems will arise. For example, if the corn plant is too high, the leaf stripping device may not be able to reach the position of the leaves that need to be processed, and if the corn plant is too short, the leaf stripping device may press down too much, causing damage to the plant, and it is also impossible to accurately strip the leaves in the predetermined manner.

[0008] Preferably: the blade-pushing mechanism includes a clamping block fixedly mounted on the outside of a connecting plate, the clamping block is rotatably connected to a connecting column inside, the connecting column is fixedly connected to a blade-pushing plate on the outside, the clamping block is fixedly connected to a mounting frame inside, a limiting plate is fixedly mounted on the top of the connecting column, the adjusting shaft is penetrated through the inside of the mounting frame, the outside of the clamping block is penetrated through the inside of the mounting frame, and the adjusting shaft and the connecting column are connected via a worm gear transmission.

[0009] Preferably, the driving shaft is arranged to penetrate the interior of the connecting frame, and a gear is fixedly connected to the outer side of the driving shaft, and the gear is meshed with the toothed belt.

[0010] Preferably: the actuator includes a frame rotatably connected to the inner side of the connecting plate, the connecting shaft is fixedly connected to the frame, the interior of the frame is fixedly connected with a bracket, the top of the bracket is fixedly connected with a reducer, the top of the reducer is fixedly connected with a servo motor, the bottom of the bracket is fixedly connected with a coupling, and the output shaft of the servo motor is transmission-connected to a male screw through the reducer and the coupling.

[0012] Preferably, the male extraction column is a conical disc wheel with a corrugated surface structure.

[0013] Compared with the prior art, the present invention has the following beneficial effects: 1. The present invention realizes the adjustment of the light intensity of the camera module through the light adjustment mechanism. When the corn plant is tall, the light is too strong, and the driving shaft rotates to drive the gear to move the adjustment plate inward to prevent overexposure caused by excessive light; when the plant is short, the adjustment plate moves outward to adjust the light intensity, thereby ensuring that the camera module can accurately capture the image of the corn plant under different lighting conditions, providing a good image basis for the subsequent accurate identification of the corn tassel and its coordinates, and at the same time locating the corn plant that has not been successfully emasculated, so that the staff can perform subsequent processing on the corn plant.

[0014] 2. The present invention realizes the effective pushing aside of the top leaves of the corn plant through the leaf pushing mechanism. According to the height of the corn plant, the control motor drives the relevant parts to rotate, and the adjustment shaft rotates to drive the connecting column to rotate, so as to adjust the opening range of the leaf pushing plate. When the plant is tall, the range increases, and when the plant is short, the range decreases, ensuring that the leaf pushing plate can effectively push aside the leaves and avoid affecting the stamen removal operation.

[0015] 3. The present invention realizes effective removal of corn stamens through an actuator. The actuator is composed of a frame, a servo motor, a reducer, a male extraction column, etc. The industrial computer controls the driving mechanism to adjust the height of the actuator according to the recognized coordinate information. At the same time, the frame deflects and moves with the rotation of the connecting shaft, driving the male extraction column to move synchronously, ensuring that the male extraction column can accurately remove the stamens, and the corrugated surface structure of the male extraction column can throw up the stamens, and cooperate with the connecting frame and the unloading mechanism to facilitate subsequent collection or composting.

[0016] In summary, the present invention connects the leaf-moving mechanism, the light adjustment mechanism and the actuator into a whole by setting a driving mechanism, so that when the height of the corn plant changes, the leaf-moving mechanism rotates to ensure accurate leaf moving, the light adjustment mechanism adaptively adjusts the light intensity as the height changes, and the actuator rotates to ensure that corn plants of different heights can be castrated.

DETAILED DESCRIPTION

[0019] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0020] See also Figures 1 to 13 The present invention provides a technical solution for a multifunctional corn tasseling detection device: A multifunctional corn tasseling detection device comprises a vehicle body 1, a connecting seat 2 is fixedly mounted on the outer side of the vehicle body 1, and a material discharge trough 21 for material discharge is provided on the inner side of the connecting seat 2; A connecting plate 9 is installed on the outer side of the connecting seat 2, and two synchronization frames 10 are rotatably connected to the outer side of the connecting plate 9. A synchronization column 11 is rotatably connected between the two synchronization frames 10, and a camera module 7 for detecting the height of corn stamens and locating the stamens is fixedly connected to the bottom of the lower synchronization frame 10; The outer side of the synchronization column 11 is fixedly connected with a light adjustment mechanism 5 for adjusting the light intensity when the camera module 7 is shooting. The light adjustment mechanism 5 includes a connection frame 51 fixedly connected to the synchronization column 11, a connection groove 53 is provided inside the connection frame 51, an adjustment plate 54 is slidably connected inside the connection groove 53, an adjustment hole 52 is provided on the connection frame 51, a control plate 55 is provided on the adjustment plate 54, and a toothed belt 56 is fixedly connected to the outer side of the adjustment plate 54; The outer side of the connecting plate 9 is provided with a leaf-pushing mechanism 4 for pushing away the leaves, and the outer side of the connecting plate 9 is also provided with an actuator 8 for executing the tasseling of corn; When working, the device is first moved to a designated position by the vehicle body 1, and then starts working; The camera module 7 captures the image of the corn plant during the operation and transmits the image to the industrial computer through a data cable. Subsequently, the industrial computer uses a pre-trained deep learning model to identify the corn tassels and their three-dimensional coordinates in the image. The industrial computer sends the identified coordinate information to the driving mechanism 6, which outputs a control signal according to the difference between the set height and the current height, thereby driving the driving mechanism 6 to adjust the height of the actuator 8 and perform the stamen removal operation through the actuator 8. At the same time, when the actuator 8 misses the stamen removal operation when performing the stamen removal operation, the camera module 7 will capture and record the corn plant that has been emasculated, and upload the position to the control center, and then locate and record the corn plant that has been successfully emasculated at that position, so that the staff can accurately locate the plant.

[0021] As an embodiment of the present invention, Figures 1 to 5As shown, a material discharge mechanism 3 is arranged on the outer side of the connection seat 2, and the material discharge mechanism 3 includes a first side conveyor belt 31 and a second side conveyor belt 34 fixedly installed on the inner side of the material discharge trough 21, a connection block 33 is fixedly installed on the top of the connection seat 2, a vertical conveyor belt 32 is arranged between the connection block 33 and the connection plate 9, and a baffle 35 is fixedly connected to the outer side of the vertical conveyor belt 32. Drivers are arranged on the outer sides of the first side conveyor belt 31, the vertical conveyor belt 32 and the connection block 33, and the first side conveyor belt 31 and the second side conveyor belt 34 rotate in opposite directions. During operation, since the extracting column 86 is a conical disc wheel with a corrugated surface structure, the stamens will be thrown up when the stamens of the corn are removed, and the thrown stamens will be thrown onto the baffle 35 under the guidance of the connecting frame 51, and the baffle 35 will convey the corn stamens to the first side conveyor belt 31 and the second side conveyor belt 34. The corn stamens entering the first side conveyor belt 31 and the second side conveyor belt 34 will be scattered on both sides of the vehicle body 1, and then enter the bottom of the corn to achieve composting, thereby preventing the corn stamens from being thrown onto the leaves of the corn, thereby causing the extracted corn stamens to rot on the leaves of the corn, which will not only cause the corn to be infected with viruses, but also cause the corn stamens to be unable to be effectively fertilized. When necessary, a collection bag can also be set at the end of the first side conveyor belt 31 and the second side conveyor belt 34 to collect the corn stamens, so that subsequent staff can detect the corn stamens.

[0022] As an embodiment of the present invention, Figures 4 to 13As shown, a driving mechanism 6 for synchronously adjusting the blade-moving mechanism 4, the light adjustment mechanism 5 and the actuator 8 is fixedly installed on the outer side of the connecting plate 9, and the driving mechanism 6 includes a control motor 61 fixedly connected to the outer side of the connecting plate 9, and the output shaft of the control motor 61 is fixedly connected to the synchronous frame 10 at the bottom, and the actuator 8 is rotatably connected to the inner side of the connecting plate 9 through a connecting shaft 62, and a connecting shaft 67 is fixedly connected to the output shaft of the control motor 61, and the connecting shaft 67 passes through the synchronous frame 10 and is connected to the adjusting shaft 64 through the first belt pair 66, and is connected to the connecting shaft 62 through transmission, and the outer side of the connecting plate 9 is fixedly connected to the belt sub-frame 63 through a fixed column 65, and a belt pair is arranged inside the belt sub-frame 63, and the outer side of the adjusting shaft 64 is driven by the belt pair inside the belt sub-frame 63. A connecting shaft 62 is connected, and a connecting shaft 67 is connected to a driving shaft 69 through a second belt pair 68. The leaf-moving mechanism 4 includes a clamping block 43 fixedly mounted on the outside of the connecting plate 9, the inside of the clamping block 43 is rotatably connected to a connecting column 42, the outside of the connecting column 42 is fixedly connected to a leaf-moving plate 41, the inside of the clamping block 43 is fixedly connected to a mounting frame 44, a limiting plate 45 is fixedly mounted on the top of the connecting column 42, an adjusting shaft 64 is set through the inside of the mounting frame 44, the outside of the clamping block 43 is set through the inside of the mounting frame 44, the adjusting shaft 64 and the connecting column 42 are connected through a worm gear set 611, a driving shaft 69 is set through the inside of the connecting frame 51, a gear 610 is fixedly connected to the outside of the driving shaft 69, and the gear 610 is meshed with a toothed belt 56; The actuator 8 includes a frame 81 rotatably connected to the inner side of the connecting plate 9, the connecting shaft 62 is fixedly connected to the frame 81, a bracket 84 is fixedly connected to the inside of the frame 81, a reducer 83 is fixedly connected to the top of the bracket 84, a servo motor 82 is fixedly connected to the top of the reducer 83, a coupling 85 is fixedly connected to the bottom of the bracket 84, and the output shaft of the servo motor 82 is connected to a male extraction column 86 through the reducer 83 and the coupling 85. The male extraction column 86 is a conical disc wheel with a corrugated surface structure.

[0023] Since corn plants have different heights, sunlight shining on them will produce different lighting effects, which may cause the camera module 7 to produce certain shooting errors due to light changes during shooting; When the camera module 7 detects that the corn plants are relatively high, the industrial control unit will command the control motor 61 to start. The rotation of the control motor 61 will drive the connecting shaft 67, thereby rotating the synchronization frame 10 at the bottom. Since a slide groove is provided between the top synchronization frame 10 and the connecting plate 9, and the top and bottom synchronization frames 10 are connected through the synchronization column 11, the rotation of the bottom synchronization frame 10 will cause the top synchronization frame 10 to rotate synchronously through the synchronization column 11, and cause the synchronization column 11 to tilt upward. The tilt of the synchronization column 11 will synchronously cause the connection frame 51 to tilt, blocking the sunlight in the area of ​​the actuator 8, thereby preventing the camera module 7 from overexposure due to excessive light when shooting the corn plants in this area. At the same time, the rotation of the connecting shaft 67 will synchronously drive the drive shaft 69, the adjustment shaft 64 and the connecting shaft 62 through the first belt pair 66, the second belt pair 68 and the belt pair in the belt pair frame 63. Rotation, the rotation of the drive shaft 69 will drive the adjustment plate 54 to move inward through the gear 610, and the inward movement of the adjustment plate 54 will make the control plate 55 thereon intersect with the adjustment hole 52 on the connection frame 51, thereby preventing light from irradiating the working area of ​​the actuator 8 through the adjustment hole 52 and the control plate 55. The rotation of the adjustment shaft 64 will drive the connection column 42 to rotate through the worm gear set 611. The rotation of the connection column 42 will increase the opening range of the two leaf-pushing plates 41, ensuring that the leaf-pushing plates 41 can effectively push away the leaves on the top of the corn plant, and avoid the actuator 8 only removing the leaves without touching the stamens when working. The rotation of the connecting shaft 62 will also synchronously drive the frame 81 to deflect and move upward, and the deflection and upward movement of the frame 81 will also cause the male extraction column 86 to deflect and move upward synchronously, ensuring that the male extraction column 86 can effectively remove the stamens of the corn and avoid damage to the leaves on the top of the corn. When the camera module 7 captures that the corn plants are relatively short, the industrial control machine will command the control motor 61 to start rotating. The rotation of the control motor 61 drives the connecting shaft 67 to rotate accordingly. The rotation of the connecting shaft 67 prompts the bottom synchronization frame 10 to start rotating. Since a slide groove is provided between the top synchronization frame 10 and the connecting plate 9, and the top and bottom synchronization frames 10 are connected by a synchronization column 11, the rotation of the bottom synchronization frame 10 will cause the top synchronization frame 10 to rotate synchronously through the synchronization column 11 and cause the synchronization column 11 to tilt downward. The tilt of the synchronization column 11 will synchronously cause the connection frame 51 to tilt, thereby reducing the obstruction of sunlight in the actuator 8 area. In this way, when the camera module 7 shoots the corn plants in the actuator 8 area, the clarity will not be affected by insufficient light. At the same time, the rotation of the connecting shaft 67 is synchronously driven through the first belt pair 66, the second belt pair 68 and the belt pair in the belt pair frame 63. The driving shaft 69, the adjusting shaft 64 and the connecting shaft 62 rotate in opposite directions. The reverse rotation of the driving shaft 69 will push the adjusting plate 54 to move outward through the gear 610. The outward movement of the adjusting plate 54 makes the control plate 55 on the adjusting plate 54 gradually contact and overlap with the adjusting hole 52 on the connecting frame 51. The light intensity passing through the adjusting hole 52 and the control plate 55 is adjusted according to the shortness of the corn plant. The reverse rotation of the adjusting shaft 64 will drive the connecting column 42 to rotate in the opposite direction through the worm gear set 611. The reverse rotation of the connecting column 42 will reduce the opening range of the two leaf prying plates 41 to prevent the leaf prying plates 41 from opening too much and making it difficult to pry open the leaves on the top of the corn plant, thereby affecting the operation of the actuator 8. The reverse rotation of the connecting shaft 62 will also synchronously drive the frame 81 to deflect and move downward. The deflection and downward movement of the frame 81 will also cause the male extraction column 86 to deflect and move downward synchronously, thereby ensuring that the male extraction column 86 can effectively remove the stamens of the corn.

[0024] As an embodiment of the present invention, Fig.14 As shown, in actual use, the actuator 8 can be adjusted to this position according to actual usage requirements. In order to meet the normal operation of the technical solution, when changing the position of the actuator 8, technical personnel in this field, while following the principles and spirit of this application, will adaptively adjust the installation position or connection relationship of other structures that cooperate with the actuator 8 to perform work, so as to meet the overall rationality and feasibility of the technical solution.

[0025] Working principle: When working, the device is first moved to the designated position through the vehicle body 1, and then starts working; The camera module 7 captures the image of the corn plant during the operation and transmits the image to the industrial computer through the data line. Subsequently, the industrial computer uses the pre-trained deep learning model to identify the corn tassels and their three-dimensional coordinates in the image. The industrial computer sends the identified coordinate information to the driving mechanism 6, which outputs a control signal according to the difference between the set height and the current height, thereby driving the driving mechanism 6 to adjust the height of the actuator 8; Since corn plants have different heights, the sunlight shining on the corn plants will also have different light levels, so the camera module 7 will have certain errors in shooting due to the light. When the camera module 7 captures a high corn plant, the industrial control machine will control the control motor 61 to rotate. After the control motor 61 rotates, it will drive the connecting shaft 67 to rotate. After the connecting shaft 67 rotates, it will drive the synchronization frame 10 at the bottom to rotate. Since a slide groove is provided between the top synchronization frame 10 and the connecting plate 9, and the top synchronization frame 10 and the bottom synchronization frame 10 are connected by a synchronization column 11, when the bottom synchronization frame 10 rotates, the top synchronization frame 10 will be driven to rotate synchronously through the synchronization column 11 and the synchronization column 11 will be tilted upward. When the synchronization column 11 tilts upward, it will synchronously drive the connection frame 51 to tilt. After the connection frame 51 tilts, it will block the sunlight in the area of ​​the actuator 8, so that when the camera module 7 takes pictures of the corn plants in the area of ​​the actuator 8, the camera module 7 will not be exposed due to excessive light. At the same time, when the connecting shaft 67 rotates, it will synchronously drive the drive shaft 69 and the adjustment shaft 69 through the first belt pair 66, the second belt pair 68 and the belt pair inside the belt pair frame 63. 4 and the connecting shaft 62 rotate, when the driving shaft 69 rotates, it will drive the adjustment plate 54 to move inward through the gear 610. After the adjustment plate 54 moves inward, the control plate 55 on the adjustment plate 54 and the adjustment hole 52 on the connecting frame 51 are staggered, so that the light will not irradiate the working area of ​​the actuator 8 through the adjustment hole 52 and the control plate 55. After the adjustment shaft 64 rotates, it will drive the connecting column 42 to rotate through the worm gear group 611. After the connecting column 42 rotates, the two leaf plates 41 will be opened to a larger range, thereby avoiding that the leaf plates 41 are opened to a smaller range, which causes the leaf plates 41 to fail to effectively open the leaves on the top of the corn plant and causes the actuator 8 to remove the leaves on the top of the corn plant when working. When the connecting shaft 62 rotates, it will synchronously drive the frame 81 to deflect and move upward. After the frame 81 deflects and moves upward, it will also drive the male extraction column 86 to deflect and move upward synchronously, thereby ensuring that the male extraction column 86 can effectively remove the stamens of the corn and avoid the loss of the leaves on the top of the corn. When the camera module 7 captures a shorter corn plant, the industrial control machine will control the control motor 61 to rotate. After the control motor 61 rotates, it will drive the connecting shaft 67 to rotate. After the connecting shaft 67 rotates, it will drive the bottom synchronization frame 10 to rotate. Since a slide groove is provided between the top synchronization frame 10 and the connecting plate 9, and the top synchronization frame 10 and the bottom synchronization frame 10 are connected by a synchronization column 11, when the bottom synchronization frame 10 rotates, the top synchronization frame 10 will be driven to rotate synchronously through the synchronization column 11 and the synchronization column 11 will be tilted downward. When the synchronization column 11 tilts downward, it will synchronously drive the connection frame 51 to tilt. After the connection frame 51 tilts, it will reduce the sunlight blocking of the actuator 8 area, so that when the camera module 7 takes pictures of the corn plants in the actuator 8 area, the camera module 7 will not shoot clearly due to weak light. At the same time, when the connecting shaft 67 rotates, it will synchronously drive the drive shaft 69 and the adjustment shaft 64 through the first belt pair 66, the second belt pair 68 and the belt pair inside the belt pair frame 63. The drive shaft 69 rotates in the opposite direction to the connecting shaft 62. When the drive shaft 69 rotates in the opposite direction, the adjustment plate 54 is driven to move outward through the gear 610. After the adjustment plate 54 moves outward, the control plate 55 on the adjustment plate 54 and the adjustment hole 52 on the connecting frame 51 gradually contact and overlap, thereby controlling the light intensity irradiated to the working area of ​​the actuator 8 through the adjustment hole 52 and the control plate 55 according to the height of the corn plant. After the adjustment shaft 64 rotates in the opposite direction, the connecting column 42 is driven to rotate in the opposite direction through the worm gear set 611. After the connecting column 42 rotates in the opposite direction, the opening range of the two leaf plates 41 becomes smaller, thereby preventing the leaf plates 41 from opening too large, which makes it difficult for the leaf plates 41 to push away the leaves on the top of the corn plant, resulting in the removal of the leaves on the top of the corn plant when the actuator 8 is working. When the connecting shaft 62 rotates in the opposite direction, it will synchronously drive the frame 81 to deflect downward. After the frame 81 deflects and moves downward, it will also drive the male extraction column 86 to deflect and move downward synchronously, thereby ensuring that the male extraction column 86 can effectively remove the stamens of the corn. Since the stamen extraction column 86 is a conical disc wheel with a corrugated surface structure, the stamens will be thrown up when the stamens of the corn are removed. The thrown stamens will be thrown onto the baffle 35 under the guidance of the connecting frame 51, and the baffle 35 will convey the corn stamens to the first side conveyor belt 31 and the second side conveyor belt 34. The corn stamens entering the first side conveyor belt 31 and the second side conveyor belt 34 will be scattered on both sides of the vehicle body 1, and then enter the bottom of the corn to achieve composting, thereby preventing the corn stamens from being thrown onto the leaves of the corn, which will cause the extracted corn stamens to rot on the leaves of the corn, which will not only cause the corn to be infected with viruses, but also make the corn stamens unable to be effectively fertilized. When necessary, a collection bag can also be set at the end of the first side conveyor belt 31 and the second side conveyor belt 34 to collect the corn stamens.

[0026] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
