Description

Technical Field

[0001] The utility model relates to the technical field of agricultural machinery, and particularly relates to a harvester. Background Art

[0002] At present, in the field of leek harvesting machinery, the harvester has made certain technical progress in recent years. However, compared with the international advanced level, we still face significant technological lags. This lag is mainly due to the insufficient investment in the research and development of agricultural machinery technology in the past and the lack of innovative thinking. The traditional leek harvesting method often relies on the disc cutter to be close to the soil layer for cutting, which not only results in a rough cutting surface and rapid tool wear, but also damages the sustainable growth of leeks.

[0003] Due to the lack of special machinery, in some areas, it is necessary to use the harvesters for crops such as wheat and rice for substitution. This is not only inefficient but also causes a great waste of resources. Especially for leeks, which are low-growing and clustered plants, the traditional sawtooth knife or disc knife harvesting method is likely to cause the crops to be arranged in a mess, bringing inconvenience to the subsequent bundling work. At the same time, considering the characteristics of the leek planting area, large harvesters are not suitable for harvesting small-area mountain leeks. Summary of the Utility Model

[0039] The present utility model relates to a harvester 100, which includes a frame 1, a cutting system 2, a bundling system 5, a conveying system 4, and a lifting system 3. The frame 1 is used to support the cutting system 2, the bundling system 5, the conveying system 4, and the lifting system 3. The cutting system 2 is used to cut crops, which are generally leeks, or can also be leafy vegetables. In the following, leeks are used to replace the crops. The bundling system 5 is used to bundle the harvested leeks. The front end of the conveying system 4 is located above the cutting system 2, and the rear end is located in front of the bundling system 5. The conveying system 4 is used to transport the leeks cut by the cutting system 2 to the bundling system 5 for bundling by the bundling system 5. The lifting system 3 is used to upright crops such as leeks that are generally prone to lodging for easy cutting.

[0040] The harvester 100 according to an embodiment of the present utility model will be described in detail below.

[0041] The two ends of the frame 1 in the first direction are respectively the front end and the rear end. The first direction is the traveling direction of the harvester 100, and the front end is the head of the traveling direction of the harvester 100. The specific shape of the frame 1 can be set according to requirements, and the shape of the frame 1 is not strictly limited.

[0042] The cutting system 2 is connected to the front end of the frame 1. The cutting system 2 includes a lower cutting plate 22 and an upper cutting plate 21. Among them, the lower cutting plate 22 is connected to the front end of the frame 1, and a plurality of lower cutting blades 24 arranged in the second direction are provided at the front end of the lower cutting plate 22. The second direction is the left-right direction of the harvester 100, which is perpendicular to the first direction.

[0043] In addition, the lower cutting blade 24 is not a flat plate in the horizontal direction, but an inclined surface that gradually slopes upward from the rear end to the front end, and the inclination angle of the lower cutting blade 24 with respect to the horizontal plane ranges from 10° to 15°.

[0044] The upper cutting plate 21 is stacked on the top surface of the lower cutting plate 22 and can move along the second direction and the first direction. A plurality of upper cutting blades 23 arranged in the second direction are provided at the front end of the upper cutting plate 21. The front end inclination angle of the upper cutting blade 23 is the same as the inclination angle of the lower cutting blade 24.

[0045] When the upper cutting plate 21 moves along the second direction, it can cut leeks. The upper cutting plate 21 can also move along the second direction. When the upper cutting plate 21 moves along the second direction, the cutting points of the upper cutting blade 23 and the lower cutting blade 24 will move backward. Since both the upper cutting blade 23 and the lower cutting blade 24 gradually rise from the rear end to the front end, the more backward the cutting points of the upper cutting blade 23 and the lower cutting blade 24 are, the lower the cutting points are. When the upper cutting blade 23 moves forward, the cutting points of the upper cutting blade 23 and the lower cutting blade 24 will move forward and the cutting points will increase. By moving the upper cutting blade 23, the height of the cutting points can be changed, which is convenient for changing the cutting points according to the height of the leeks.

[0046] The cutting machine of the present utility model can accurately adjust the cutting length of leeks according to actual needs and can also adapt to the growth state of leeks. The lengths and thicknesses of leeks in different batches or growth environments may vary. The adjustable upper cutting blade 23 can better adapt to these changes and ensure the consistency of the cutting effect. In addition, there is no need to frequently replace cutting blades of different specifications. By adjusting the upper cutting blade 23, it can quickly adapt to different cutting tasks, saving time and labor and improving the cutting efficiency. Appropriate adjustment can reduce the over-extrusion or pulling of leeks caused by improper blade positions, thus maximizing the integrity and freshness of leeks. For novice or unskilled operators, this adjustable function provides more flexibility and error tolerance, reduces the difficulty of cutting operations, and also facilitates daily maintenance and deep cleaning, extending the service life of the cutter.

[0047] As a preferred solution, the lower cutting blade 24 and the upper cutting blade 23 have the same shape. The width range of the cutting edge of the lower cutting blade 24 is 2 cm to 8 cm. The thickness range of the cutting edges of the lower cutting blade 24 and the upper cutting blade 23 is 1 mm to 5 mm.

[0048] For thinner leek stems, the blade widths of the lower cutting knife 24 and the upper cutting knife 23 can be designed to be 2 cm to 3 cm. Such a width can ensure that when cutting, the blades can quickly and accurately cut the leeks while avoiding unnecessary damage to the surrounding leeks. And the blade thicknesses of the lower cutting knife 24 and the upper cutting knife 23 can be controlled within 1 mm to 2 mm to ensure the sharpness of the blades, make the cutting smoother, and reduce the extrusion and damage to the leek stems.

[0049] For medium-thick leek stems, the blade widths of the lower cutting knife 24 and the upper cutting knife 23 can be designed to be 3 cm to 5 cm. This width can adapt to the size of the leek stems and effectively perform cutting. The blade thicknesses of the lower cutting knife 24 and the upper cutting knife 23 are 2 mm to 3 mm, which can not only maintain the strength of the blades but also ensure sharpness to achieve efficient cutting.

[0050] For thicker leek stems, thicker leek stems require wider blades, which can be designed to be 5 cm to 8 cm. The wider blades can completely cut the thicker leek stems at one time. The blade thicknesses of the lower cutting knife 24 and the upper cutting knife 23 can be increased to 3 mm to 5 mm to enhance the durability and stability of the blades and withstand greater cutting forces.

[0051] The moving distance of the upper cutting plate 21 along the first direction is less than or equal to 10 cm. That is to say, the moving range of the upper cutting knife 23 back and forth can be set between ±5 cm, and 0 represents the overlapping position of the upper cutting knife 23 and the lower cutting knife 24, and the thickness is taken from 0 mm to 3 mm.

[0052] The vertical distance between the lower cutting plate 22 and the bottom end of the harvester 100 ranges from 8 cm to 30 cm.

[0053] For leeks with a height of 10 cm - 20 cm, the blade height of the lower cutting knife 24 can be designed to be 8 cm to 18 cm. This can ensure that the leeks can be completely cut during harvesting, while avoiding cutting too deep into the soil, reducing the damage to the soil structure and the wear of the blades.

[0054] For leeks with a height of 20 cm to 30 cm, the blade height of the lower cutting knife 24 should be set between 18 cm and 28 cm. This height can adapt to the growth height of the leeks, effectively perform cutting, and will not miss part of the leeks due to too high a blade.

[0055] For individual leeks with a height exceeding 30 cm, the blade height of the lower cutting knife 24 can be designed to be about 28 cm to 35 cm. However, in actual design, factors such as the lodging situation of the leeks, the harvesting efficiency, and the stability of the machine also need to be considered.

[0056] The lower cutting plate 22 includes a bottom cutting plate 221 and an inclined plate 222. The bottom cutting plate 221 is a horizontally arranged plate and is stacked on the bottom surface of the upper cutting plate 21. A plurality of the lower cutting knives 24 are provided at the front end of the bottom cutting plate 221.

[0057] The bottom end of the inclined plate 222 is connected to the rear end of the bottom cutting plate 221, and the top end gradually increases towards the rear end and is connected to the frame 1. The inclined plate 222 is gradually inclined towards the rear end and is connected to the connecting plate of the frame 1. This connecting plate is also in an inclined state and the inclined surface is the same as that of the inclined plate 222.

[0058] In addition, the connecting plate of the frame 1 is provided with a plurality of mounting positions at different heights. These mounting positions are multiple mounting grooves or a plurality of screw holes at different heights. And the inclined plate 222 is provided with a plurality of mounting holes. Any one of the mounting holes can be connected to any one of the mounting positions through a bolt. By using bolts, the mounting holes and different mounting positions can be connected, thereby adjusting the position of the lower cutting plate 22 in the first direction. Since the inclined plate 222 of the lower cutting plate 22 is inclined, the inclined plate 222 can move up or down along the connecting plate, and then adjust the height of the entire lower cutting plate 22 to adapt to leeks of different heights.

[0059] Furthermore, the cutting system 2 further includes two drivers, two eccentric wheels and two driving rods. The two drivers are respectively defined as a first driver 251 and a second driver, the two eccentric wheels are respectively defined as a first eccentric wheel 252 and a second eccentric wheel 261, and the two driving rods are respectively defined as a first driving rod 253 and a second driving rod 262.

[0060] The first driver 251 is a motor. This motor is connected to the upper cutting plate 21, and the axis of the output shaft of the first driver 251 extends along the first direction. The first eccentric wheel 252 is connected to the output shaft of the first driver 251 and can rotate along with the rotating shaft of the first driver 251.

[0061] One end of the first driving rod 253 is connected to the first eccentric wheel 252, and the other end is connected to the upper cutting plate 21.

[0062] When the first driver 251 is started, it can drive the first eccentric wheel 252 to rotate. And the first driving rod 253 is connected to the first eccentric wheel 252 and can move in the second direction along with the rotation of the first eccentric wheel 252.

[0063] At Figure 3-4In the specific embodiment shown, two driving plates 27 arranged at intervals along the second direction are provided on the top surface of the bottom cutting plate 221, and the bottom ends of the driving plates 27 are connected to the top surface of the upper cutting plate 21. The axis of the first driving rod 253 does not overlap with the axis of the output shaft of the first driver 251, and the first driving rod 253 is located between the two driving plates 27. When the first driver 251 rotates, the first eccentric wheel 252 can rotate accordingly. Since the axis of the first driving rod 253 does not overlap with the axis of the output shaft of the first driver 251, the first driving rod 253 can rotate as the first eccentric wheel 252 rotates, and drive the two driving plates 27 to drive the upper cutting plate 21 to move along the second direction.

[0064] The second driver is also a motor. The second driver is connected to the inclined plate 222 of the lower cutting plate 22, and the axis of the output shaft of the second driver extends along the second direction. The second eccentric wheel 261 is connected to the output shaft of the second driver. One end of the second driving rod 262 is movably connected to the upper cutting plate 21, and the other end is connected to the second eccentric wheel 261.

[0065] Specifically, a rotating shaft 28 is provided on the top surface of the upper cutting plate 21. A shaft hole is provided at the front end of the second driving rod 262, and the shaft hole is rotatably connected to the rotating shaft 28. The rear end of the second driving rod 262 is connected to the second eccentric wheel 261. The second eccentric wheel 261 rotates as the second driver rotates, and drives the second driving rod 262 to move back and forth during rotation. The second driving rod 262 drives the upper cutting plate 21 to move back and forth along the first direction, thereby adjusting the height of the cutting point.

[0066] The rice-planting assisting system 3 is connected to the frame 1 and includes two rice-planting assisting plates 31, two first rotating shafts 32, two turntables 33 and a plurality of rice-planting assisting devices 34.

[0067] Among them, the two rice-planting assisting plates 31 are arranged at intervals along the second direction and are located at the front end of the frame 1, and are used to lift the lodged leeks to facilitate cutting.

[0068] The rice-planting assisting plate 31 is an arc-shaped plate that gradually increases in height from the front end to the rear end, and the radius of the rice-planting assisting plate 31 ranges from 25 mm to 50 mm, that is, the curvature radius is 20 - 40 (1 / mm 2 ). As a preferred solution, the radius of the rice-planting assisting plate 31 is 33 mm.

[0069] By collecting basic data and conducting in-depth analysis, a relatively accurate harvesting trajectory model was established. Designing the reel board 31 by calculating the arc curvature of the human hand has many advantages. In a specific embodiment, the radius of the reel board 31 is 33 mm, which is the curvature of the maximum opening angle between the thumb and index finger. This curvature can improve the ergonomic performance, make the shape of the reel board 31 more conform to the natural movement trajectory of the human hand, enable the force applied to the reel board 31 to be more effectively converted into the energy required for work, reduce energy loss, and improve work efficiency.

[0070] In another embodiment, the reel board 31 includes a straight segment and an arc segment connected to each other. The arc segment is located at the bottom end of the straight segment and the radius range of the arc segment is 25 mm to 50 mm. That is to say, the straight segment is a flat plate with a gradually increasing inclination from the front end to the rear end, and the arc segment is integrally formed with the straight segment and is located at the front end of the straight segment. The radius of the arc segment is preferably 33 mm, which also refers to the arc curvature of the human thumb and index finger.

[0071] The first rotating shaft 32 is rotatably connected to the frame 1 and its axis extends in the vertical direction. Specifically, the frame 1 includes a top mounting plate 12 and a bottom mounting plate 11, wherein the top mounting plate 12 is located above the bottom mounting plate 11.

[0072] The top ends of the two first rotating shafts 32 are respectively rotatably connected to the top mounting plate 12 through bearings, and the bottom ends are respectively rotatably connected to the bottom mounting plate 11 through bearings. The rear ends of the two reel boards 31 are respectively connected to the top mounting plate 12, and the front ends are respectively connected to the bottom mounting plate 11, so that the front ends of the reel boards 31 are lower than the rear ends. That is to say, the two first rotating shafts 32 are respectively located below the two reel boards 31 near the rear ends.

[0073] The two turntables 33 are respectively sleeved outside the two first rotating shafts 32. The multiple reel grippers 34 are divided into two groups. The multiple reel grippers 34 in each group of reel grippers 34 are evenly spaced around the circumference of the turntable 33 and the inner ends are connected to the turntable 33, that is, spaced around the axis of the first rotating shaft 32, and the outer ends extend outside the turntable 33. When the first rotating shaft 32 rotates, the reel grippers 34 can be driven to rotate around its axis through the turntable 33.

[0074] One side of the reel gripper 34 is an arc surface 341 and the other side is a flat surface. The radius range of the arc surface 341 of the reel gripper 34 is preferably 25 mm - 50 mm. The radius of the arc surface 341 of the reel gripper 34 is more preferably 33 mm. Designing the reel gripper 34 by calculating the arc curvature of the human hand has many advantages.

[0075] First, it can improve ergonomic performance, making the shape of the reel 34 more conform to the natural movement trajectory of the human hand, reducing fatigue and discomfort during operation, and thus improving the work efficiency and comfort of the operator.

[0076] Secondly, it enhances the accuracy and stability of operation. Designed according to the curvature of the human hand arc, it enables the operator to control the reel 34 more precisely, reduces the probability of operation errors, and ensures the operation quality.

[0077] Furthermore, it helps to optimize the mechanical performance, enabling the force applied to the reel 34 to be more effectively converted into the energy required for work, reducing energy loss, and improving work efficiency.

[0078] The plane where the reel 34 is located is basically flush with the foremost end of the reel board 31.

[0079] The shape of the movement trajectory of the reel 34 is determined by the ratio of the circumferential speed Vy of the reel 34 to the forward speed Vm of the harvester 100; it is the reel speed ratio. Only when ≥ 1, is it possible to guide the leek stalks towards the cutter for cutting and continue to push the stalks backward after cutting to avoid accumulation and blockage on the cutter. When > 1, the working condition of the reel 34 is normal. During the working process of the reel 34, the reel 34 needs to have good working quality. In addition to satisfying > 1, it should also meet the requirements of different stages during the working process. During cutting, the reel should support the crop stalks to cooperate with cutting and prevent the cutter from pushing the stalks forward.

[0080] The harvester 100 further includes a transmission mechanism 6 and another driver, and this driver is defined as the third driver 7.

[0081] The transmission mechanism 6 is installed on the frame 1 and is connected to the first rotating shaft 32 and the conveying system 4. The third driver 7 is connected to the transmission mechanism 6 and can drive the transmission system and the first rotating shaft 32 to rotate through the transmission mechanism 6.

[0082] Specifically, as Figure 1-5 shown, the transmission mechanism 6 includes two identical sets of transmission components. Each transmission component respectively includes two gear sets, two belt pulleys 62, and a belt 63. One of the gear sets is the first gear set 61. The first gear set 61 includes three meshing gears. One of the gears is sleeved outside the first rotating shaft 32, and the other two gears are respectively connected to two rotating shafts, and this rotating shaft is defined as the second rotating shaft 64. The second rotating shaft 64 extends in the vertical direction and is rotatably connected to the bottom mounting plate 11 or rotatably connected to other parts of the frame 1.

[0083] One of the pulleys 62 and a gear are sleeved on the same second rotating shaft 64, and the other pulley 62 is sleeved on the third rotating shaft 65. A roller is also arranged outside the third rotating shaft 65. The two pulleys 62 are driven by a belt 63.

[0084] The third rotating shaft 65 is in the vertical direction and is rotatably connected to the frame 1. The third rotating shaft 65 is located at the front end of the frame 1 and above the upper cutting plate 21. The third rotating shafts 65 of the two transmission components are arranged at intervals in the second direction.

[0085] The transmission component further includes a fourth rotating shaft 67. The axis of the fourth rotating shaft 67 extends in the second direction and is connected to the rear end of the frame 1. The fourth rotating shaft 65 is located in front of the bundling system 5 and the fourth rotating shaft 67 is significantly higher than the third rotating shaft 65. The fourth rotating shafts 65 of the two transmission components are arranged at intervals in the vertical direction and are respectively provided with rollers. The conveying system 4 includes two conveyor belts, and the two conveyor belts are respectively sleeved on the sleeves outside the third rotating shafts 65 of the two transmission components and the sleeves outside the fourth rotating shafts 65, so as to gradually pour the vertical leeks into a horizontal state and transport them to the rear bundling system 5.

[0086] The other gear set is the second gear set 66. The second gear set 66 also includes three gears, and the three gears are arranged in the vertical direction and adjacent two gears are meshed. Two of the gears are respectively connected to the fourth rotating shafts 65 of the two transmission components, and the other gear is connected to the output shaft of the third driver 7. The third driver 7 is also a motor. The third driver 7 drives the fourth rotating shaft 67 and the third rotating shaft 65 to rotate through the second gear set 66, and the third rotating shaft 65 drives the first rotating shaft 28 to rotate through the two pulleys 62 and the first gear set 61.

[0087] The frame 1 includes two mounting plates 13 arranged at intervals in the second direction and a guide plate 14 located between the two mounting plates 13. The two mounting plates 13 are located at the rear end of the frame 1, and the guide plate 14 is connected to the tops of the two mounting plates 13. The guide plate 14 is an arc-shaped plate that gradually increases in height from the rear end to the front end, and the guide plate 14 is located between the conveying system 4 and the bundling system 5. The front end of the guide plate 14 is located between the sleeves outside the two fourth rotating shafts 65, facilitating the reception of the leeks conveyed by the two conveyor belts. The rear end of the guide plate 14 is located above the bundling system 5, and the leeks can flow into the bundling system 5 through the guide plate 14.

[0088] In a specific embodiment, the bundling system 5 includes a turning plate 51, a grabbing ring 52, a wire pulling rod 53, and a knotting device 54. Among them, the turning plate 51 is plate-shaped and located below the rear end of the guiding plate 14. The turning plate 51 is rotatably connected to the two mounting plates 13 through a fifth rotating shaft. The axis of the fifth rotating shaft extends along the second direction. The turning plate 51 can receive the leeks transported by the conveying system 4, and when receiving enough leeks, it turns the leeks into the grabbing ring 52 for bundling.

[0089] The grabbing ring 52 is ring-shaped and has an opening. The middle part of the grabbing ring 52 along the circumferential direction is rotatably connected to the two mounting plates 13 through a sixth rotating shaft. The grabbing ring 52 is located below the turning plate 51 and can receive the leeks from the turning plate 51.

[0090] The wire pulling rod 53 is rotatably connected to the two mounting plates 13 through a seventh rotating shaft and is located behind the grabbing ring 52, and is used to pull the bundling wire into the grabbing ring 52 and bundle the leeks. The axes of the seventh rotating shaft and the sixth rotating shaft are respectively parallel to the fifth rotating shaft and are located behind the fifth rotating shaft.

[0091] The knotting device 54 is connected to the frame 1 and is located in front of the grabbing ring 52, and is used to tie a knot in the bundling wire. The knotting device 54 is any available instrument in the prior art, and the specific implementation manner of the knotting device 54 is not limited.

[0092] The bundling system 5 is arranged to be able to rotate and switch between the harvesting state, the bundling state, and the completion state in turn.

[0093] In the harvesting state, the wire pulling rod 53 pulls the bundling wire from the knotting device 54 and places it into the grabbing ring 52, and grabs the end of the bundling wire. The turning plate 51 turns the received leeks into the grabbing ring 52 and places them on the bundling wire. The opening of the grabbing ring 52 faces the top, which is convenient for receiving the leeks transported by the turning plate 51.

[0094] In the bundling state, the turning plate 51 continues to receive the leeks transported by the conveying system 4 in a new round, while the grabbing ring 52 rotates forward. The wire pulling rod 53 pulls the end of the bundling wire and bypasses the leeks to the knotting device 54, and the knotting device 54 ties a knot in the bundling wire to complete the bundling.

[0095] In the completion state, the grabbing ring 52 rotates backward, and the bundled leeks are separated from the grabbing ring 52. The grabbing ring 52 rotates forward to receive a new round of leeks transported by the turning plate 51 again.

[0096] As a preferred solution, the frame 1 further includes a receiving plate 15 located below the flipping plate 51. The flipping plate 51 can rotate between the receiving plate 15 and the guiding plate 14. In addition, both ends of the receiving plate 15 are respectively connected to the two mounting plates 13 and are provided with three avoiding grooves 153.

[0097] The two grab rings 52 are respectively located in the two avoiding grooves 153 and can flip from the back surface of the receiving plate 15 to exceed its top surface. The knotter 54 is located below the guiding plate 14 and at the front end of the receiving plate 15.

[0098] The thread pulling rod 53 is located between the two grab rings 52 and includes a straight segment and an arc segment connected to each other. The bottom end of the straight segment is connected to the seventh rotating shaft, and the top end is connected to the bottom end of the arc segment. The top end of the arc segment of the thread pulling rod 53 can pass through the other avoiding groove 153 and rotate to the knotter 54, deliver the thread end to the knotter 54 and pull out a new thread end.

[0099] In addition, the flipping plate 51 is further provided with an avoiding opening, which is aligned with the thread pulling rod 53 for avoiding the thread pulling rod 53.

[0100] As a preferred solution, the receiving plate 15 includes a first section 151 and a second section 152. The first section 151 is an arc-shaped plate that gradually increases in height from the rear end to the front end and bends towards the front end. The front end of the second section 152 is connected to the bottom end of the first section 151, and the second section 152 is an arc-shaped plate that gradually increases in height from the rear end to the front end and bends towards the front end.

[0101] In the bundling state, the grab rings 52 rotate forward so that the leeks are located between the grab rings 52 and the first section 151, that is, the leeks are restricted by the first section 151 of the receiving plate 15 and the grab rings 52, thereby forming a compact state for convenient bundling.

[0102] In the completed state, the grab rings 52 rotate backward, and the bundled crops are separated from the grab rings 52 and move along the second section 152 to the outside. The second section 152 is equivalent to guiding the bundled leeks to the outside.

[0103] Of course, the harvester 100 further includes a motor for driving the fifth rotating shaft, the sixth rotating shaft and the seventh rotating shaft to rotate.

[0104] The harvester 100 further includes a sensing device 8 and a control device. The control device is connected to the sensing device 8 and the above-mentioned multiple drivers, and is used for receiving the signal of the sensing device 8 and controlling the operation of the above-mentioned multiple drivers.

[0105] The induction device 8 is used to sense the height of crops. The induction device 8 is preferably machine vision technology, which can automatically identify the position of leeks, achieve precise harvesting, and improve the harvesting efficiency and quality. In addition, using the PyTorch framework and PyCharm environment, a leek recognition system based on convolutional neural network is realized. First, a dataset containing various vegetables is constructed, and pictures of vegetables such as leeks are scientifically and accurately classified and preprocessed to ensure the diversity and effectiveness of the data. Then, the fully connected classification layer model is used to learn and train the training set, and the model performs excellently on the test set, with an accuracy close to 90%. The trained weight model is saved, and verification and prediction are carried out. The results show that the recognition confidence of the model for leeks is as high as 93.5566%, verifying the high precision of the model. Finally, the model is applied to actual image recognition. By connecting an external camera to capture images and preprocessing and recognizing the images, high-confidence recognition of leeks is achieved, and the confidence reaches 0.95. The entire project process is scientific and reasonable, and the technical implementation is mature and stable, providing strong support for subsequent image recognition applications.

[0106] In a specific embodiment, data can be collected through a binocular depth camera and a lidar, and the GPU processing power can be used for image recognition and depth information analysis to calculate the optimal harvesting path in real time. Then, through wifi connection, the data is sent to the control device, and the control device can control the speed of the harvester 100, adjust the height of the cutting system 2, etc.

[0107] The specific operation process of the harvester 100 is as follows: when the harvester 100 enters the field, the lifter 31 will guide the single-row leeks into the harvesting path. Subsequently, the lifter will straighten the leeks, and the [specific part not clear in the original] is responsible for further straightening and clamping the leeks. Then, the cutting system 2 makes a reciprocating motion to precisely cut the leeks. The cut leeks are immediately conveyed to the bundling system 5 through a conveyor belt, marking the completion of the harvesting process. The design of the harvester 100 of the present utility model has high flexibility and can adapt to the harvesting needs of different crops. Moreover, by using machine vision technology, that is, by simulating the visual function of the human eye through a computer to identify, measure and process leek images, the adaptability of the harvester 100 to crops can be improved, and the production efficiency can be significantly enhanced.

[0108] The commercial leek harvester 100 mainly relies on gasoline engines for driving, which not only generates a large amount of polluting waste gas during the harvesting process, causing serious pollution to the environment and the atmosphere, but also goes against the current development trend of green environmental protection. To address this problem, a solar panel is also installed on the top of the frame 1 of the present utility model for energy storage. The introduction of the solar panel provides a continuous source of green energy for the harvester 100, enabling the harvester 100 to operate independently without relying on external power sources or fuels, greatly expanding its usage scenarios.
