[0049] The 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 straw supporting system 3. The frame 1 is used to support the cutting system 2, the bundling system 5, the conveying system 4 and the straw supporting system 3. The cutting system 2 is used to cut crops, which are generally leeks, but can also be leafy vegetables. Leeks will be used to replace crops in the following text. 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, so that the bundling system 5 can be used for bundling. The straw supporting system 3 is used to stand up crops that are generally prone to lodging, such as leeks, to facilitate cutting.

[0050] The harvester 100 according to an embodiment of the present invention is described in detail below.

[0051] The two ends of the frame 1 along the first direction are the front end and the rear end respectively. The first direction is the direction of travel of the harvester 100, and the front end is the head of the harvester 100 in the direction of travel. The specific shape of the frame 1 can be set according to needs and is not strictly limited.

[0052] The cutting system 2 is connected to the front end of the frame 1 and includes a lower cutting plate 22 and an upper cutting plate 21. The lower cutting plate 22 is connected to the front end of the frame 1 and is provided with a plurality of lower cutting blades 24 arranged along a second direction. The second direction is the left-right direction of the harvester 100 and is arranged perpendicular to the first direction.

[0053] In addition, the lower cutter 24 is not a flat plate in the horizontal direction, but a slope that gradually tilts upward from the rear end to the front end, and the inclination angle of the lower cutter 24 to the horizontal plane ranges from 10° to 15°.

[0054] 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. The front end of the upper cutting plate 21 is provided with a plurality of upper cutting knives 23 arranged along the second direction, and the front end inclination angle of the upper cutting knife 23 is the same as the inclination angle of the lower cutting knife 24.

[0055] The upper cutting plate 21 can cut the leeks when it moves in the second direction. The upper cutting plate 21 can also move in the second direction. When the upper cutting plate 21 moves in the second direction, the cutting points of the upper cutter 23 and the lower cutter 24 move backward. Since both the upper cutter 23 and the lower cutter 24 gradually rise from the rear end to the front end, the further the cutting points of the upper cutter 23 and the lower cutter 24 move backward, the lower the cutting points become. When the upper cutter 23 moves toward the front end, the cutting points of the upper cutter 23 and the lower cutter 24 move forward, increasing their height. By moving the upper cutter 23, the height of the cutting point can be changed, making it easier to adjust the cutting point according to the height of the leeks.

[0056] The cutting machine of the present invention can accurately adjust the cutting length of leeks according to actual needs, and can also adapt to the growth status of leeks. The length and thickness of leeks from different batches or growing environments may vary. The adjustable upper cutter 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 knives of different specifications. By adjusting the upper cutter 23, it is possible to quickly adapt to different cutting tasks, saving time and manpower and improving cutting efficiency. Appropriate adjustment can reduce the excessive squeezing or pulling of leeks due to improper blade position, thereby maintaining the integrity and freshness of the leeks to the greatest extent. For first-time users or unskilled operators, this adjustable function provides more flexibility and fault tolerance, reduces the difficulty of cutting operations, and facilitates daily maintenance and deep cleaning, thereby extending the service life of the cutter.

[0057] As a preferred solution, the lower cutter 24 and the upper cutter 23 have the same shape, and the blade width of the lower cutter 24 ranges from 2 cm to 8 cm. The blade thickness of the lower cutter 24 and the upper cutter 23 ranges from 1 mm to 5 mm.

[0058] For thinner leek stems, the blade width of the lower and upper cutters 24 and 23 can be designed to be 2 to 3 cm. This width ensures that the blades can quickly and accurately cut through the leeks while avoiding unnecessary damage to surrounding leeks. The blade thickness of the lower and upper cutters 24 and 23 can be controlled to be 1 to 2 mm to ensure blade sharpness, making cutting smoother and reducing compression and damage to the leek stems.

[0059] For medium-thick leek stems, the blade width of the lower and upper cutters 24 and 23 can be designed to be 3 cm to 5 cm. This width adapts to the size of the leek stems and effectively cuts them. The blade thickness of the lower and upper cutters 24 and 23 is 2 mm to 3 mm, which maintains blade strength while ensuring sharpness and efficient cutting.

[0060] Thicker leek stems require wider blades, which can be designed to be 5cm to 8cm. A wider blade can completely cut through thicker leek stems in one go. The blade thickness of the lower and upper cutters 24 and 23 can be increased to 3mm to 5mm to enhance the durability and stability of the blades and withstand greater cutting forces.

[0061] The movement distance of the upper cutting plate 21 along the first direction is less than or equal to 10 cm. In other words, the range of the front-back movement of the upper cutter 23 can be set between ±5 cm, and 0 represents the overlapping position of the upper cutter 23 and the lower cutter 24, and the thickness is 0 mm to 3 mm.

[0062] The vertical distance between the lower cutting plate 22 and the bottom end of the harvester 100 is in the range of 8 cm to 30 cm.

[0063] For leeks with a height of 10 cm to 20 cm, the blade height of the lower cutter 24 can be designed to be 8 cm to 18 cm. This ensures that the leeks can be completely cut during harvesting while avoiding cutting too deep into the soil, reducing damage to the soil structure and wear on the blade.

[0064] For leeks with a height of 20cm to 30cm, the blade height of the lower cutter 24 should be set between 18cm and 28cm. This height can adapt to the growth height of the leeks, effectively cut them, and will not miss some leeks because the blade is too high.

[0065] For leeks with a height of more than 30 cm, the blade height of the lower cutter 24 can be designed to be about 28 cm to 35 cm. However, in actual design, factors such as the lodging of leeks, harvesting efficiency and stability of the machine also need to be considered.

[0066] 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 lower cutting knives 24 are provided at the front end of the bottom cutting plate 221 .

[0067] 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 toward the rear end and is connected to the frame 1. The inclined plate 222 is gradually inclined toward the rear end and is connected to the connecting plate of the frame 1. The connecting plate is also inclined and has the same inclined surface as the inclined plate 222.

[0068] Furthermore, the connecting plate of the frame 1 is provided with multiple mounting locations at different heights, which are formed as multiple mounting slots or multiple screw holes at different heights. The inclined plate 222 is provided with multiple mounting holes, any of which can be connected to any of the mounting locations via bolts. Bolts can be used to connect the mounting holes to different mounting locations, thereby adjusting the position of the lower cutting plate 22 along the first direction. Because the inclined plate 222 of the lower cutting plate 22 is inclined, it can move up or down along the connecting plate, thereby adjusting the height of the entire lower cutting plate 22 to accommodate leeks of varying heights.

[0069] Furthermore, the cutting system 2 also includes two drivers, two eccentric wheels and two drive rods, the two drivers are defined as the first driver 251 and the second driver respectively, the two eccentric wheels are defined as the first eccentric wheel 252 and the second eccentric wheel 261 respectively, and the two drive rods are defined as the first drive rod 253 and the second drive rod 262 respectively.

[0070] The first driver 251 is a motor connected to the upper cutting plate 21. 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.

[0071] 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 .

[0072] The first driver 251 is activated to 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 along the second direction as the first eccentric wheel 252 rotates.

[0073] exist Figure 3-4 In the illustrated embodiment, the top surface of the bottom cutting plate 221 is provided with two drive plates 27 spaced apart along the second direction. The bottom ends of the drive plates 27 are connected to the top surface of the upper cutting plate 21. The axis of the first drive rod 253 does not overlap with the axis of the output shaft of the first driver 251, and the first drive rod 253 is located between the two drive plates 27. When the first driver 251 rotates, the first eccentric 252 rotates accordingly. Since the axis of the first drive rod 253 does not overlap with the axis of the output shaft of the first driver 251, the first drive rod 253 rotates with the first eccentric 252, driving the two drive plates 27 to move the upper cutting plate 21 in the second direction.

[0074] The second driver is also a motor. It is connected to the inclined plate 222 of the lower cutting plate 22, with the axis of the second driver's output shaft extending along the second direction. The second eccentric 261 is connected to the output shaft of the second driver. One end of the second drive rod 262 is movably connected to the upper cutting plate 21, and the other end is connected to the second eccentric 261.

[0075] Specifically, the top surface of the upper cutting plate 21 is provided with a rotation shaft 28, and the front end of the second drive rod 262 is provided with an axial hole that is rotatably connected to the rotation shaft 28. The rear end of the second drive rod 262 is connected to the second eccentric wheel 261. The second eccentric wheel 261 rotates with the rotation of the second actuator, driving the second drive rod 262 to move back and forth during the rotation process. The second drive rod 262 drives the upper cutting plate 21 to move back and forth in the first direction, thereby adjusting the height of the cutting point.

[0076] The crop supporting system 3 is connected to the frame 1 and includes two crop supporting plates 31 , two first rotating shafts 32 , two rotating disks 33 and a plurality of crop supporting devices 34 .

[0077] Among them, two leek supporting 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 support the fallen leek to facilitate cutting.

[0078] The support 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 support plate 31 is in the range of 25mm-50mm, that is, the curvature radius is 20-40 (1 / mm 2 As a preferred solution, the radius of the supporting plate 31 is 33 mm.

[0079] By collecting basic data and conducting in-depth analysis, a relatively accurate harvesting trajectory model was established. Designing the straw support plate 31 by calculating the curvature of the human hand offers numerous advantages. In one embodiment, the radius of the straw support plate 31 is 33 mm, which is the curvature at the maximum angle when the thumb and index finger are open. This curvature improves ergonomics, allowing the shape of the straw support plate 31 to better align with the natural movement trajectory of the human hand. This allows the force applied to the straw support plate 31 to be more effectively converted into the energy required for work, reducing energy loss and improving work efficiency.

[0080] In another embodiment, the support plate 31 comprises a connected straight segment and an arc segment. The arc segment is located at the bottom of the straight segment and has a radius ranging from 25 mm to 50 mm. In other words, the straight segment is a flat plate with a gradually increasing inclination from the front to the back, while the arc segment is integrally formed with the straight segment and located at the front end. The radius of the arc segment is preferably 33 mm, which is also based on the curvature of the human thumb and index finger.

[0081] The first rotating shaft 32 is rotatably connected to the frame 1 and its axis extends in a 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 .

[0082] The top ends of the two first rotating shafts 32 are rotatably connected to the top mounting plate 12 via bearings, and the bottom ends are rotatably connected to the bottom mounting plate 11 via bearings. The rear ends of the two supporting plates 31 are connected to the top mounting plate 12, while the front ends are connected to the bottom mounting plate 11, respectively. This allows the front ends of the supporting plates 31 to be lower than the rear ends. In other words, the two first rotating shafts 32 are located below the rear ends of the two supporting plates 31.

[0083] The two rotating disks 33 are respectively sleeved onto the outside of the two first rotating shafts 32. The plurality of crop supporters 34 are divided into two groups. The crop supporters 34 in each group are evenly spaced around the circumference of the rotating disk 33 and connected to the rotating disk 33 at their inner ends. That is, they are spaced around the axis of the first rotating shaft 32 and their outer ends extend outside the rotating disk 33. When the first rotating shaft 32 rotates, the crop supporters 34 can be driven to rotate around their axes via the rotating disk 33.

[0084] The crop support 34 has a curved surface 341 on one side and a flat surface on the other. The radius of the curved surface 341 of the crop support 34 is preferably in the range of 25 mm to 50 mm. More preferably, the radius of the curved surface 341 of the crop support 34 is 33 mm. Designing the crop support 34 by calculating the curvature of the human hand offers numerous advantages.

[0085] Firstly, it can improve ergonomics, making the shape of the straw support 34 more in line with the natural movement trajectory of the human hand, reducing fatigue and discomfort during operation, thereby improving the work efficiency and comfort of the operator.

[0086] Secondly, it enhances the accuracy and stability of operation. Designed according to the curvature of the human hand, it allows the operator to control the straw support 34 more accurately, reducing the probability of operational errors and ensuring the quality of operation.

[0087] Furthermore, it helps to optimize the mechanical properties so that the force applied to the straw supporter 34 can be more effectively converted into the energy required for work, thereby reducing energy loss and improving work efficiency.

[0088] The plane where the crop supporting device 34 is located is substantially flush with the front end of the crop supporting plate 31 .

[0089] The shape of the motion trajectory of the straw supporter 34 is determined by the ratio of the circumferential speed Vy of the straw supporter 34 to the forward speed Vm of the harvester 100; this is the straw-pulling speed ratio. Only when it is ≥1, it is possible to guide the leek stems to the cutter to cooperate with the cutting, and continue to push the stems backward after cutting to avoid accumulation and blockage on the cutter. When it is >1, the working condition of the straw supporter 34 is normal. During the working process of the straw supporter 34, the straw supporter 34 is required to have good working quality. In addition to meeting >1, it should also meet the requirements of different stages of the working process. During cutting, the straw wheel should support the crop stems to cooperate with the cutting to prevent the cutter from pushing the stems forward.

[0090] The harvester 100 further includes a transmission mechanism 6 and another drive, which is defined as a third drive 7 .

[0091] The transmission mechanism 6 is mounted on the frame 1 and connected to the first rotating shaft 32 and the transmission 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 .

[0092] Specifically, if Figure 1-5 As shown, the transmission mechanism 6 includes two identical transmission components, each of which includes two gear sets, two pulleys 62, and a belt 63. One of the gear sets is a first gear set 61, which includes three meshing gears, one of which is sleeved on the outside of the first rotating shaft 32, and the other two gears are connected to two rotating shafts, which are defined as second rotating shafts 64. The second rotating shaft 64 extends in a vertical direction and is rotatably connected to the bottom mounting plate 11 or to other parts of the frame 1.

[0093] One of the pulleys 62 and a gear are sleeved on the same second rotating shaft 64, and another pulley 62 is sleeved on the 3rd rotating shaft 65, and a roller is also set outside the 3rd rotating shaft 65. Belt 63 is transmitted between the two pulleys 62.

[0094] The third rotating shaft 65 is vertically connected to the frame 1 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 spaced apart along the second direction.

[0095] The transmission assembly also includes a fourth rotating shaft 67, whose axis 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 is significantly higher than the third rotating shaft 65. The fourth rotating shafts 65 of the two transmission components are spaced apart vertically and each is equipped with a roller. The conveyor system 4 includes two transmission belts, which are respectively mounted on sleeves outside the third rotating shaft 65 and the fourth rotating shaft 65 of the two transmission components. This belt gradually tilts the vertical leeks into a horizontal position and transports them to the bundling system 5 at the rear.

[0096] The other gear set is the second gear set 66, which also includes three gears arranged vertically, with adjacent gears meshing. Two of the gears are connected to the fourth rotating shafts 65 of the two transmission components, respectively, and the third 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 through the second gear set 66. The third rotating shaft 65 drives the first rotating shaft 28 through two pulleys 62 and the first gear set 61.

[0097] The frame 1 includes two mounting plates 13 spaced apart along the second direction, and a guide plate 14 positioned 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. The guide plate 14 is positioned between the conveyor system 4 and the bundling system 5. The front end of the guide plate 14 is positioned between the sleeves outside the two fourth rotating shafts 65, facilitating the reception of leeks transported by the two conveyor belts. The rear end of the guide plate 14 is positioned above the bundling system 5, allowing the leeks to flow into the bundling system 5 through the guide plate 14.

[0098] In a specific embodiment, the bundling system 5 includes a flip plate 51, a grab ring 52, a wire pulling rod 53 and a knotter 54, wherein the flip plate 51 is plate-shaped and is located below the rear end of the guide plate 14. The flip 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 flip plate 51 can receive the leeks transported by the conveying system 4, and when enough leeks are received, the leeks are flipped into the grab ring 52 for bundling.

[0099] The grab ring 52 is annular and has an opening. The middle part of the grab ring 52 along the circumference is rotatably connected to the two mounting plates 13 through a sixth rotating shaft. The grab ring 52 is located below the flip plate 51 and can receive the leeks on the flip plate 51.

[0100] The wire pulling rod 53 is rotatably connected to the two mounting plates 13 via a seventh rotating shaft and is located behind the grab ring 52. It is used to pull the tying wire into the grab ring 52 and tie the leeks. The axes of the seventh and sixth rotating shafts are respectively parallel to the fifth rotating shaft and are located behind the fifth rotating shaft.

[0101] The knotter 54 is connected to the frame 1 and is located in front of the grab ring 52 for tying a knot of the tying wire. The knotter 54 is any instrument available in the prior art and does not limit the specific implementation of the knotter 54.

[0102] The baling system 5 is configured to be switchable between a harvesting state, a baling state and a finished state.

[0103] In the harvesting state, the wire pulling rod 53 pulls the binding wire from the knotter 54 and places it into the grabbing ring 52, and grabs the thread end of the binding wire. The flip plate 51 flips the received leeks into the grabbing ring 52 and is located on the binding wire. The opening of the grabbing ring 52 faces the top, which is used to facilitate the reception of the leeks transported by the flip plate 51.

[0104] In the bundling state, the flip plate 51 continues to receive a new round of leeks transported by the conveying system 4, and the grab ring 52 rotates forward, the wire pulling rod 53 pulls the end of the tying wire and wraps it around the leeks to the knotter 54, and the knotter 54 ties the tying wire to complete the bundling.

[0105] In the completed state, the grab ring 52 rotates toward the rear, and the bundled leeks are separated from the grab ring 52. The grab ring 52 rotates toward the front to receive a new round of leeks transported by the turnover plate 51.

[0106] As a preferred solution, the frame 1 further includes a receiving plate 15 located below the flip plate 51, and the flip plate 51 can rotate between the receiving plate 15 and the guide 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 avoidance grooves 153.

[0107] The two grab rings 52 are respectively located in the two avoidance grooves 153 and can be turned over from the back side of the receiving plate 15 to exceed the top surface thereof. The knotter 54 is located below the guide plate 14 and at the front end of the receiving plate 15.

[0108] 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 another avoidance groove 153 and rotate to the knotter 54, where it delivers the thread end to the knotter 54 and pulls out a new thread end.

[0109] In addition, the flip plate 51 is further provided with an escape opening, which is aligned with the thread pulling rod 53 and is used to avoid the thread pulling rod 53 .

[0110] As a preferred embodiment, the receiving plate 15 includes a first section 151 and a second section 152. The first section 151 is a curved plate that gradually increases in height from the rear end to the front end and curves toward the front end. The front end of the second section 152 is connected to the bottom end of the first section 151. The second section 152 is a curved plate that gradually increases in height from the rear end to the front end and curves toward the front end.

[0111] In the bundling state, the grab ring 52 rotates forward and places the leeks between the grab ring 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 ring 52 , thereby forming a compact state to facilitate bundling.

[0112] In the completed state, the gripping ring 52 rotates toward the rear, and the bundled crops are separated from the gripping ring 52 and move to the outside along the second section 152. The second section 152 is equivalent to leading the bundled leeks to the outside.

[0113] 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.

[0114] 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 plurality of drivers mentioned above, and is used to receive signals from the sensing device 8 and control the operation of the plurality of drivers mentioned above.

[0115] The sensing device 8 is used to sense the height of the crops. This sensing device 8 is preferably based on machine vision technology, capable of automatically identifying the location of leeks, enabling precise harvesting and improving harvesting efficiency and quality. Furthermore, a leek recognition system based on a convolutional neural network can be implemented using the PyTorch framework and the PyCharm environment. First, a dataset containing a variety of vegetables was constructed, and images of vegetables such as leeks were scientifically and accurately classified and preprocessed to ensure data diversity and validity. Then, a fully connected classification layer model was used to train the training set. The model performed excellently on the test set, with an accuracy rate approaching 90%. The trained weighted model was saved and validated and predicted. The results showed that the model's recognition confidence for leeks reached 93.5566%, verifying the model's high accuracy. Finally, the model was applied to actual image recognition. Images were captured using an external camera, and the images were preprocessed and recognized, achieving high-confidence recognition of leeks, reaching a confidence level of 0.95. The entire project process is scientific and rational, and the technology is mature and stable, providing strong support for subsequent image recognition applications.

[0116] In a specific embodiment, data can be collected through a binocular depth camera and a lidar, and image recognition and depth information analysis can be performed using GPU processing capabilities to calculate the optimal harvesting path in real time. The data is then sent to a control device via a Wi-Fi connection. The control device can control the speed of the harvester 100, adjust the height of the cutting system 2, etc.

[0117] The specific operating process of the harvester 100 is as follows: when the harvester 100 enters the field, the straw support plate 31 will guide the single row of leeks into the harvesting path. Afterwards, the straw support straightens the leeks, and the straw support plate 31 is responsible for further straightening and clamping the leeks. Subsequently, the cutting system 2 performs reciprocating motion to accurately cut the leeks. The cut leeks are immediately conveyed to the bundling system 5 via a conveyor belt, marking the completion of the harvesting process. The design of the harvester 100 of the present invention is highly flexible and can adapt to the harvesting needs of different crops. Moreover, the use of machine vision technology, that is, the computer simulates the visual function of the human eye to identify, measure and process the leek image, can improve the adaptability of the harvester 100 to crops and significantly improve production efficiency.

[0118] Commercial leek harvesters 100 are primarily powered by gasoline engines, which not only produces a large amount of polluting waste gas during the harvesting process, causing serious environmental and atmospheric pollution, but also runs counter to current trends in green environmental protection. To address this issue, the present invention also incorporates solar panels on top of the frame 1 for energy storage. The introduction of solar panels provides the harvester 100 with a continuous source of green energy, enabling it to operate autonomously without relying on external power or fuel, greatly expanding its potential applications.
