Description

Technical Field

[0001] This invention belongs to the field of harvester technology, and particularly relates to a low-damage harvesting device and control method for soybean-maize intercropping. Background Technology

[0002] Soybeans, as my country's fourth largest grain crop, are an important agricultural product for both grain and oilseed production. Currently, losses from mechanized soybean harvesting are a serious problem, with losses due to the header accounting for more than half of the total losses, a considerable amount. Therefore, addressing header losses is of great significance for improving soybean harvest rates.

[0003] Most soybean harvesters now have conveyor belts on their headers for automatic transport of harvested crops. However, the reel material is currently mostly rigid, which is detrimental to soybean harvesting. Specifically, it causes significant impact on the soybean stalks, leading to severe pod breakage during feeding and resulting in losses. Regarding the reel structure, when harvesting lodged crops, the impact of the reel teeth on the soybeans can also cause pod breakage and grain loss, severely impacting farmers' income. As for reel speed, when harvesting lodged crops, excessively high reel speeds increase the impact on the grains, while excessively low speeds allow the stalks to be pushed down by the header cutter, increasing grain loss. Finally, regarding header height, when operating in complex and rugged terrain, soybean combine harvesters are prone to inconsistent stalk cutting heights, poor adjustment accuracy, and significant crop losses. Summary of the Invention

[0004] The purpose of this invention is to provide a low-loss reeling device and control method for soybean-maize intercropping to solve the above-mentioned problems. It can adjust the opening and closing of the reeling spring teeth and control the rotation speed and height during operation to reduce the loss of the cutting platform during harvesting, depending on whether the crop is lodged or not.

[0005] To achieve the above objectives, the present invention provides the following solution: a low-damage harvesting device for soybean-maize intercropping, comprising a harvesting platform, and further comprising:

[0006] A reel assembly includes a reel spindle, with support frames at both ends of the reel spindle. A plurality of flexible reeling plates are evenly distributed around the reel spindle between the two sets of support frames. A plurality of reeling springs are connected to the flexible reeling plates by a position adjustment component. The position adjustment component is used to adjust the angular relationship between the reeling springs and the reeling plates.

[0007] The height adjustment assembly includes a frame hinged to the header, the reel spindle rotatably connected to one end of the frame, and a height adjustment component provided between the frame and the header;

[0008] A driving component is disposed between the frame and the reel spindle, and the driving component is used to drive the reel spindle to rotate.

[0009] The monitoring components include a height monitoring element disposed on the cutting table, a position monitoring element disposed on the height adjustment element, and a speed sensor disposed on the drive element.

[0010] Preferably, the flexible reeling board includes a reeling board, with both ends of the reeling board hinged between two sets of support frames, a reeling board angle maintaining member provided between the reeling board and one of the support frames, and a position adjusting member provided on one side of the reeling board.

[0011] Preferably, both the reeling board and the reeling spring teeth are made of flexible material.

[0012] Preferably, the position adjusting component includes a reeling tooth shaft rotatably connected to one side of the reeling board, a plurality of reeling springs fixedly connected at equal intervals to the reeling tooth shaft, and the plurality of reeling springs are arranged in parallel. A small motor is fixedly connected to the reeling board, and the output shaft of the small motor is coaxially fixedly connected to one end of the reeling tooth shaft. A tensioning bolt is also threaded onto the reeling board, and the end of the tensioning bolt is correspondingly arranged to the side wall of the reeling tooth shaft. The tensioning bolt is used to prevent the reeling tooth shaft from rotating relative to the reeling board during operation.

[0013] Preferably, the reeling board has a plurality of hidden grooves, and the plurality of hidden grooves are correspondingly arranged with a plurality of reeling teeth, the hidden grooves being used to accommodate the reeling teeth.

[0014] Preferably, the height adjustment component includes two sets of hydraulic cylinders, one end of each set of hydraulic cylinders is hinged to both sides of the cutting table, and the other end of each set of hydraulic cylinders is hinged to the frame. The position monitoring component is mounted on one of the hydraulic cylinders.

[0015] Preferably, the height monitoring device includes two sets of ultrasonic sensors and two sets of tilt sensors, with the two sets of ultrasonic sensors and the two sets of tilt sensors respectively fixedly connected to the bottom of the two opposite side walls of the cutting table.

[0016] Preferably, the position monitoring component includes a hydraulic displacement sensor fixedly connected to the hydraulic cylinder, the hydraulic displacement sensor being used to monitor the length of the extension end of the hydraulic cylinder.

[0017] A control method for a low-damage seed-pulling device in soybean-maize intercropping includes the following control process:

[0018] For harvesting lodged crops, the position adjustment component is used to make a certain angle between several seed-pulling teeth and the flexible seed-pulling plate, ensuring that the seed-pulling position of the seed-pulling teeth is at 2 / 3 of the crop height;

[0019] For crops that do not lodge during harvest, a position adjustment device is used to make several seed-lifting springs fit into a flexible seed-lifting board, and the flexible seed-lifting board is used to achieve the seed-lifting effect.

[0020] During operation, the height detection device monitors the height of the header. If the height of the header exceeds the set range, the height adjustment device adjusts the frame to a suitable height to control the height of the reeling.

[0021] During operation, the rotational speed of the drive unit is monitored by a speed sensor. When the crop density is high, the drive unit increases its rotational speed, and when the crop density is low, the drive unit decreases its rotational speed.

[0022] Compared with the prior art, the present invention has the following advantages and technical effects: the main function of the flexible rake-lifting plate is to lift crops that are not lodged; the main function of the rake-lifting spring teeth is to lift lodged crops; the main function of the position adjustment component is to adjust the angle between the rake-lifting spring teeth and the flexible rake-lifting plate to achieve two working modes: harvesting lodged crops and harvesting non-lodged crops; the main function of the height adjustment component is to adjust the height of the rake reel spindle by adjusting the angle between the frame and the horizontal plane; the main function of the drive component is to drive the rake reel spindle to rotate; the main function of the height monitoring component is to detect the height of the header; the main function of the position monitoring component is to monitor the status of the height adjustment component; and the main function of the speed sensor is to monitor the speed of the drive component. Overall, this invention employs sensor monitoring technology and flexible materials. Based on whether the crop is lodged or not, sensors and related control components can adjust the rotation speed and height of the reel, as well as the opening and closing of the reeling spring teeth and the flexible reeling plate. By adjusting the working state of the reel, the force on the soybeans during the reeling process is reduced. While ensuring the normal operation of the header and the reel, the reel is prevented from tangling and is automatically controlled, which can reduce crop loss in the harvester.

[0030] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0031] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0032] Reference Figures 1-5 This invention provides a low-damage harvesting device for soybean-maize intercropping, including a harvesting platform 20, and further comprising:

[0033] The reel assembly includes a reel spindle 17, with support frames 19 at both ends of the reel spindle 17. Several flexible reeling plates are evenly distributed around the reel spindle 17 between the two sets of support frames 19. Several reeling spring teeth 3 are connected to the flexible reeling plates through position adjustment components. The position adjustment components are used to adjust the angle relationship between the reeling spring teeth 3 and the reeling plates.

[0034] The height adjustment assembly includes a frame 7 hinged to the header 20, a reel spindle 17 rotatably connected to one end of the frame 7, and a height adjustment component provided between the frame 7 and the header 20.

[0035] A drive unit is located between the frame 7 and the reel spindle 17. The drive unit is used to drive the reel spindle 17 to rotate.

[0036] The monitoring components include a height monitoring component mounted on the cutting table 20, a position monitoring component mounted on the height adjustment component, and a speed sensor mounted on the drive component.

[0037] The main function of the flexible reeling plate is to reel crops that are not lodged; the main function of the reeling spring 3 is to reel lodged crops; the main function of the position adjustment component is to adjust the angle between the reeling spring 3 and the flexible reeling plate to achieve two working modes: harvesting lodged crops and harvesting non-lodged crops; the main function of the height adjustment component is to adjust the height of the reeling reel main shaft 17 by adjusting the angle between the frame 7 and the horizontal plane; the main function of the drive component is to drive the reeling reel main shaft 17 to rotate; the main function of the height monitoring component is to detect the height of the header 20; the main function of the position monitoring component is to monitor the status of the height adjustment component; and the main function of the speed sensor is to monitor the speed of the drive component. Overall, this invention employs sensor monitoring technology and flexible materials. Based on whether the crop is lodged or not, sensors and related control components can adjust the rotation speed and height of the reel, as well as the opening and closing of the reeling spring teeth and the flexible reeling plate. By adjusting the working state of the reel, the force on the soybeans during the reeling process is reduced. While ensuring the normal operation of the header and the reel, the reel is prevented from tangling and is automatically controlled, which can reduce crop loss in the harvester.

[0038] Further optimization of the scheme also includes a controller (not shown in the figure), which can be installed in the cab and is electrically connected to the position adjustment component, height adjustment component, drive component, height monitoring component, position monitoring component, and speed sensor.

[0039] Further optimization of the scheme: the flexible rice-pulling board includes a rice-pulling board 2, with both ends of the rice-pulling board 2 hinged between two sets of support frames 19 respectively. An angle maintaining component for the rice-pulling board is provided between the rice-pulling board 2 and a support frame 19, and a position adjusting component is provided on one side of the rice-pulling board 2.

[0040] The design was further optimized so that both the reeling board 2 and the reeling spring teeth 3 are made of flexible materials.

[0041] like Figure 3 and Figure 4 As shown, when harvesting crops that are not lodged, the reeling teeth 3 retract into the reeling board 2. At this time, the reeling board 2 is in direct contact with the crops. When harvesting lodged crops, the reeling teeth 3 extend out from the reeling board 2 and directly contact the crops to perform the reeling function. Therefore, by making the reeling board 2 and the reeling teeth 3 into flexible materials, the impact on the soybean stalks can be reduced, and serious pod bursting can be avoided during the soybean feeding process, thus reducing losses.

[0042] Further optimization of the scheme: the position adjustment component includes a reeling tooth shaft 1 rotatably connected to one side of the reeling plate 2, a number of reeling spring teeth 3 are fixedly connected to the reeling tooth shaft 1 at equal intervals and the number of reeling spring teeth 3 are arranged in parallel, a small motor 14 is fixedly connected to the reeling plate 2, the output shaft of the small motor 14 is coaxially fixedly connected to one end of the reeling tooth shaft 1, and a tensioning bolt 13 is also threadedly connected to the reeling plate 2, the end of the tensioning bolt 13 is correspondingly set to the side wall of the reeling tooth shaft 1, the tensioning bolt 13 is used to prevent the reeling tooth shaft 1 from rotating relative to the reeling plate 2 during operation.

[0043] The scheme is further optimized by providing several hidden grooves 15 on the reeling board 2. The hidden grooves 15 are correspondingly set with several reeling spring teeth 3. The hidden grooves 15 are used to accommodate the reeling spring teeth 3.

[0044] like Figure 3 and Figure 4 As shown, when harvesting crops that do not lodge, the operator first loosens the tension bolts 13 at one end of several reeling plates 2, disengaging the threaded ends of the tension bolts 13 from the reeling tooth shaft 1. Then, the controller controls several small motors 14 to rotate, causing the reeling tooth shaft 1 to rotate synchronously. Several reeling teeth 3 on the reeling tooth shaft 1 move towards the reeling plate 2 under this action and eventually enter the trough 15, achieving the retrieval of the reeling teeth 3. Afterward, the tension bolts 13 are tightened to prevent the reeling tooth shaft 1 from rotating. At this time, when the drive unit drives the reeling plates 2 to rotate via the reeling wheel main shaft 17 and support frame 19, the reeling plates 2 directly contact the crops, achieving the reeling effect.

[0045] When harvesting lodged crops, the operator first loosens all the loosening bolts 13. Then, the controller controls several small motors 14 to rotate in the opposite direction, causing several reeling teeth 3 to rotate out of the grooves 15 and form a 90-degree angle with the reeling plate 2. After that, the loosening bolts 13 are tightened. At this time, as the reeling plate 2 rotates around the main shaft 17 of the reeling wheel, the reeling teeth 3 directly contact two-thirds of the crop, achieving the reeling effect.

[0046] In a further optimized design, the two ends of the reeling plate 2 are rotatably connected to the sides of the two support frames 19 via rotating shafts. One end of the reeling wheel main shaft 17 is fixedly connected to a fixed wheel 16. The axis of the fixed wheel 16 is parallel to the axis of the reeling wheel main shaft 17 but deviates from it. An outer rotating frame 18 is rotatably sleeved on the axial side wall of the fixed wheel 16. One end of the crank 12 is fixedly connected to the rotating shaft at the end of the reeling plate 2 near the outer rotating frame 18. The other end of the crank 12 is hinged to the side of the outer rotating frame 18.

[0047] like Figure 2 and Figure 5As shown, when the drive unit drives the support frame 19 to rotate via the reel spindle 17, the cranks 12 on the reel plates 2 will drive the outer rotating frame 18 to rotate around the fixed wheel 16. Because the fixed wheel 16 causes an eccentric rotation between the outer rotating frame 18 and the support frame 19, there is rotation between the reel plates 2 and the support frame 19 during operation, thus ensuring that the reel plates 2 always remain parallel to the horizontal plane during operation.

[0048] The design was further optimized, and the driving component included a hub motor 8, the output shaft of which was fixedly connected coaxially to the reel main shaft 17.

[0049] The design is further optimized so that the height adjustment component includes two sets of hydraulic cylinders 6. One end of each set of hydraulic cylinders 6 is hinged to both sides of the cutting table 20, and the other end of each set of hydraulic cylinders 6 is hinged to the frame 7. The position monitoring component is set on one of the hydraulic cylinders 6.

[0050] like Figure 1 As shown, by extending the hydraulic cylinder 6 under the control of the controller, the height of the frame 7 relative to the header 20 can be raised, thereby raising the height of the reel spindle 17 at the end of the frame 7. Similarly, by shortening the hydraulic cylinder 6 under the control of the controller, the height of the reel spindle 17 can be lowered.

[0051] The design was further optimized so that the height monitoring components include two sets of ultrasonic sensors 9 and two sets of tilt sensors 10, which are fixedly connected to the bottom of the two opposite side walls of the cutting table 20.

[0052] During system initialization, before operation, the crop height and automatic control threshold ΔH are input into the controller. The controller calculates the target height H0 and reads the signals from the ultrasonic sensor 9 and the tilt sensor 10 to calculate the current header height H. If |H0-H|<ΔH, then there is no need to control the hydraulic cylinder 6; otherwise, the extension and retraction of the hydraulic cylinder 6 are automatically controlled according to the magnitude of H and H0 to achieve control of the reel height.

[0053] Further optimization of the scheme includes a position monitoring component, which includes a hydraulic displacement sensor 11 fixedly connected to the hydraulic cylinder 6. The hydraulic displacement sensor 11 is used to monitor the length of the extension end of the hydraulic cylinder 6.

[0054] like Figure 2 As shown, the hydraulic displacement sensor 11 is used to detect the extension length of the hydraulic cylinder 6 and transmit the monitoring signal to the controller to realize closed-loop control of the height of the reel.

[0055] Further optimization of the design: the bottom of the header 20 is equipped with several cutters 4 for cutting crop stalks, and the sides of the header 20 are also equipped with crop lifters 5.

[0056] A control method for a low-damage seed-pulling device in soybean-maize intercropping includes the following control process:

[0057] For harvesting lodged crops, the position adjustment component is used to make a certain angle between several reeling spring teeth 3 and the flexible reeling plate, so as to ensure that the reeling position of the reeling spring teeth 3 is at 2 / 3 of the crop height;

[0058] When harvesting lodged crops, the operator first loosens all the loosening bolts 13. Then, the controller controls several small motors 14 to rotate in the opposite direction, causing several reeling teeth 3 to rotate out of the grooves 15 and form a 90-degree angle with the reeling plate 2. After that, the loosening bolts 13 are tightened. At this time, as the reeling plate 2 rotates around the main shaft 17 of the reeling wheel, the reeling teeth 3 directly contact two-thirds of the crop, achieving the reeling effect.

[0059] For crops that do not lodge during harvest, a number of seed-lifting spring teeth 3 are brought into contact with the flexible seed-lifting plate by the position adjustment component, and the flexible seed-lifting plate is used to achieve the seed-lifting effect.

[0060] When harvesting lodged crops, the operator first loosens all the loosening bolts 13. Then, the controller controls several small motors 14 to rotate in the opposite direction, causing several reeling teeth 3 to rotate out of the grooves 15 and form a 90-degree angle with the reeling plate 2. After that, the loosening bolts 13 are tightened. At this time, as the reeling plate 2 rotates around the main shaft 17 of the reeling wheel, the reeling teeth 3 directly contact two-thirds of the crop, achieving the reeling effect.

[0061] During operation, the height detection component monitors the height of the header 20. If the height of the header 20 exceeds the set range, the height adjustment component adjusts the frame 7 to a suitable height to control the height of the reeling.

[0062] During system initialization, before operation, the crop height and automatic adjustment threshold ΔH are input into the controller. The controller calculates the target height H0 and reads the signals from the ultrasonic sensor 9 and tilt sensor 10 to calculate the current header height H. If |H0-H| < ΔH, then the hydraulic cylinder 6 does not need to be controlled. If |H0-H| > ΔH and H0 is greater than H, the reel needs to be raised. In this case, the controller controls the hydraulic cylinder 6 to extend outward by a set length and monitors whether the hydraulic cylinder 6 has extended to the set length through the hydraulic displacement sensor 11. At this time, the reel height is raised, making |H0-H| < ΔH, and the length of the hydraulic cylinder 6 remains unchanged. Similarly, when |H0-H| > ΔH and H0 is less than H, the control system controls the hydraulic cylinder 6 to shorten by a set length, lowering the reel height, making |H0-H| < ΔH, and maintaining the length of the hydraulic cylinder 6 remains unchanged.

[0063] During operation, the rotational speed of the drive unit is monitored by a speed sensor. When the crop density is high, the drive unit increases its rotational speed, and when the crop density is low, the drive unit decreases its rotational speed.

[0064] like Figure 2 As shown, the rotational speed of the hub motor 8 is monitored by a transmission sensor. The hub motor 8 controls the rotational speed of the reel spindle 17 to maintain it between 1.5 and 2 times the machine's forward speed. Simultaneously, while keeping the harvester's forward speed constant, the controller appropriately increases the rotational speed of the hub motor 8 during high-density crop harvesting and decreases it during low-density crop harvesting. By continuously improving the speed, header losses during soybean harvesting are reduced.
