Description

Technical Field

[0001] The present invention relates to the technical field of crop harvesting, and in particular to a high-efficiency crop harvesting robot and a control method thereof. Background Art

[0002] In agricultural production, leek is a common vegetable with high economic value, and its harvesting process is crucial. Traditional leek harvesting mainly relies on manual operation. Farmers need to hold simple tools such as sickles and bend down to harvest row by row. This method not only consumes a lot of time and energy, but also has extremely low harvesting efficiency. For example, in a large leek planting base, a skilled worker can only harvest a limited area a day, which seriously affects the overall production progress. At the same time, the quality of manual harvesting is uneven, and it is difficult to ensure that the root length of each leek is consistent, which affects the subsequent sales and consumption of leeks.

[0003] At present, there are also some mechanical equipment for harvesting leeks on the market. Most of these equipment use simple cutting devices, which drive the cutting knives through motors to cut, and directly dump the harvested leeks on the ground, which are then collected and sorted manually.

[0004] However, there are many problems with existing leek harvesting technology and equipment. In actual operation scenarios, when faced with leeks of different growth heights and densities, traditional equipment cannot accurately adjust the cutting height and effectively guide the leeks. This results in the leeks being easily scattered during the harvesting process, making subsequent collection difficult, and failing to meet the diverse needs of different users for the reserved length of the leek roots. At the same time, due to the lack of automated sorting and efficient collection mechanisms, the entire harvesting process still requires a large amount of manpower to participate, labor costs remain high, and work efficiency is difficult to improve. These problems have seriously restricted the modernization and efficiency of leek harvesting. Therefore, the present invention provides an efficient crop harvesting robot and a control method thereof to address the deficiencies in the prior art. Summary of the invention

[0012] Preferably, a mounting block is fixedly connected to the bottom of the collecting bucket, a tension spring telescopic rod is provided at one end of the mounting block, one end of the tension spring telescopic rod is rotatably connected to a baffle, the outer side of the baffle is fitted with the outer side of the cover plate, and the outer sides of the baffle are in contact with the outer sides of two limit blocks.

[0013] A control method for an efficient crop harvesting robot comprises the following steps: Step 1: Adjust the height of the movable baffle bar and the movable center bar according to the height of the crops; Step 2: Start the driving wheels and the driving motor to make the robot move forward and harvest crops; Step 3: adjusting the deflection angles of the two movable plates according to the density of the harvested crops, and starting the conveyor belt to convey the harvested crops into the collecting bucket; Step 4: After turning off the robot, open the cover and take out the crops in the collection bucket.

[0019] The following will be combined with the drawings in the specification of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0020] Please refer to the attached Figure 1 -Attached Figure 5An embodiment of the present invention provides an efficient crop harvesting robot, comprising a U-shaped frame 1. An auxiliary cutting mechanism is provided on one side of the U-shaped frame 1, and the auxiliary cutting mechanism comprises two fixed baffles 2 and two movable baffles 3. One end of the two fixed baffles 2 is respectively fixedly connected to the edge of one side of the U-shaped frame 1, and the movable baffle 3 is located directly above the fixed baffle 2. A fixed center bar 4 is fixedly connected to the middle position of one side of the U-shaped frame 1, and the tops of the fixed baffles 2 and the fixed center bar 4 are both fixedly connected to guide columns 8. The outer side of the middle guide column 8 is slidably connected to the active center bar 5, and the outer sides of the other two guide columns 8 are both slidably connected to the active baffles 3. The tops of the fixed baffles 2 and the fixed center bar 4 are both rotatably connected to the screw rod 6, and the inner sides of the movable baffles 3 and the active center bar 5 are respectively threadedly connected to the outer sides of the corresponding screw rod 6, and the top of the screw rod 6 is fixedly connected to a rotating disk 7. When the height of the two movable baffles 3 and the movable center bar 5 needs to be adjusted, the operator can stand on one side of the U-shaped plate frame 1, hold the rotating disk 7 with both hands, and rotate the rotating disk 7 clockwise or counterclockwise, and use the threaded connection relationship between the screw rod 6 and the movable baffles 3 and the movable center bar 5 to realize the movable baffles 3 and the movable center bar 5 to rise or fall smoothly along the guide column 8. The guide column 8 plays a precise guiding role, ensuring that the movable baffles 3 and the movable center bar 5 will not deviate during the lifting process, thereby ensuring the effective definition and regularity of the leek growth area. A cutting mechanism is provided at the bottom of the U-shaped plate frame 1, and the cutting mechanism includes an electric telescopic rod 10, which is installed at the bottom of the U-shaped plate frame 1, and its control switch is set on the operation panel of the U-shaped plate frame 1. The output end of the electric telescopic rod 10 is fixedly connected with a mounting box 11, and a drive motor 12 is installed inside the mounting box 11, and a cutting wheel 13 is fixedly connected to the output end of the drive motor 12. When fine-tuning the height of the cutting wheel 13, the operator controls the telescopic length of the electric telescopic rod 10 through the corresponding button on the operation panel. The telescopic movement of the electric telescopic rod 10 drives the installation box 11 and the drive motor 12 and the cutting wheel 13 inside to rise and fall synchronously, thereby accurately adjusting the distance between the cutting wheel 13 and the ground to meet the different reserved length requirements of the leek roots. A moving mechanism is arranged on the outside of the U-shaped plate frame 1, and the moving mechanism includes two driving wheels 16, which are arranged at the bottom of the U-shaped plate frame 1 and driven by a built-in motor. Before the robot starts the harvesting operation, it is necessary to ensure that the built-in motors of the two driving wheels 16 are in normal working condition. The operator starts the motor of the driving wheel 16 through the operation panel, so that the driving wheel 16 starts to rotate, providing the robot with forward power. A collecting bucket 14 is fixedly connected to the other side of the U-shaped plate frame 1, and two rollers 15 are rotatably connected to the bottom of the collecting bucket 14. A collecting mechanism is arranged on the inner side of the U-shaped frame 1, and the collecting mechanism includes a conveyor belt 9, which is installed on the inner side of the U-shaped frame 1 and driven by an independent motor. The control switch of the motor is also arranged on the operation panel of the U-shaped frame 1.When the cut leeks fall to the conveyor belt 9 under the guidance of the fixed baffle 2, the movable baffle 3, the fixed center bar 4 and the movable center bar 5, the operator starts the motor of the conveyor belt 9, and the conveyor belt 9 starts to run, and the leeks are smoothly transported to the inside of the collecting bucket 14. A rotating shaft 17 is arranged inside the collecting bucket 14, and the outside of the rotating shaft 17 is rotatably connected to two movable plates 18, and the bottom of the movable plate 18 is fixedly connected to two supporting plates 19, and the bottom of the supporting plate 19 is rotatably connected to a connecting rod 20. An electric telescopic rod 21 is installed inside the collecting bucket 14, and its control button is also arranged on the operation panel. When it is necessary to adjust the gap between the movable plate 18 and the collecting bucket 14, the operator presses the corresponding button on the operation panel according to the accumulation of leeks in the collecting bucket 14 to control the extension and retraction of the electric telescopic rod 21. The telescopic movement of the electric telescopic rod 21 drives the connecting rod 20 to rotate around the rotation connection point with the support plate 19, so that the support plate 19 drives the movable plate 18 to deflect around the rotating shaft 17, thereby realizing flexible adjustment of the size of the gap. A capping mechanism is provided on the outside of the collecting bucket 14, and the capping mechanism includes a cover plate 25, which is rotatably connected to the outside of the collecting bucket 14, and two limit blocks 26 are fixedly connected to the outside of the cover plate 25. A mounting block 22 is fixedly connected to the bottom of the collecting bucket 14, and a tension spring telescopic rod 23 is provided at one end of the mounting block 22, and a baffle 24 is rotatably connected to one end of the tension spring telescopic rod 23, and the outside of the baffle 24 is in contact with the outside of the cover plate 25, and the outer sides of the baffle 24 are in contact with the outer sides of the two limit blocks 26. When taking out the leeks in the collecting bucket 14, the operator first manually grasps the baffle 24 and pulls it out from the position in contact with the two limit blocks 26, and then rotates the baffle 24 180 degrees with the rotation connection point of the tension spring telescopic rod 23 and the mounting block 22 as the center. At this time, the cover plate 25 is no longer restricted by the baffle 24, and the operator can rotate the cover plate 25 to open the collecting bucket 14, so as to conveniently and quickly take out the leeks accumulated inside.

[0021] Specifically, first, facing the leeks with different growth conditions in the leek field, it is necessary to adjust the height of the two movable baffles 3 and the movable center bar 5. The operator stands on one side of the U-shaped plate frame 1, holds the rotating disk 7 with both hands, and drives the screw rod 6 to rotate by rotating the rotating disk 7 clockwise or counterclockwise. Since the inner sides of the movable baffles 3 and the movable center bar 5 are respectively threadedly connected to the outer sides of the corresponding screw rod 6, and when the screw rod 6 rotates, the movable baffles 3 and the movable center bar 5 slide along the guide column 8. The effect of this is that the positions of the movable baffles 3 and the movable center bar 5 can be accurately adjusted according to the actual growth height of the leeks, ensuring that they can effectively regularize and guide the leeks, limit the leeks to a specific area, and prepare for subsequent neat harvesting. Then, according to different harvesting requirements, the operator starts the electric telescopic rod 10 through the corresponding button on the operation panel to fine-tune the height of the cutting wheel 13. The telescopic movement of the electric telescopic rod 10 drives the installation box 11 and the drive motor 12 and the cutting wheel 13 inside it to rise and fall synchronously. This operation can accurately control the distance between the cutting wheel 13 and the ground, thereby accurately controlling the reserved length of the root of the leek, meeting the different requirements of different users for the root length of the leek after harvesting, and ensuring that the harvested leek meets a variety of usage scenarios. Next, start the built-in motors of the two driving wheels 16 and the driving motor 12. The driving wheel 16 rotates to provide the robot with forward power, so that the robot can move forward smoothly in the leek field; at the same time, the output shaft of the driving motor 12 drives the cutting wheel 13 to rotate at high speed. At this time, the robot moves forward and the high-speed rotating cutting wheel 13 harvests the leek. In this process, the fixed baffle 2, the movable baffle 3, the fixed center bar 4, and the movable center bar 5 play a key role. They can divide the harvested leek into two parts, and effectively prevent the cut leek from falling to both sides under the forward force of the robot, ensuring that the leek remains relatively neat during the harvesting process, avoiding the leek from scattering, and facilitating subsequent collection. As the robot continues to move forward, due to the guidance of the fixed baffle 2, the movable baffle 3, the fixed center bar 4, and the movable center bar 5, the cut leek head will fall to the position of the conveyor belt 9. At this time, the operator starts the motor of the conveyor belt 9, and the conveyor belt 9 starts to run, which has the effect of smoothly conveying the fallen leek to the inside of the collecting bucket 14. The setting of the conveyor belt 9 greatly improves the collection efficiency, avoids the cumbersome process of manual collection one by one, and ensures the continuity of the harvesting work. After the leek enters the collecting bucket 14, it will roll down from the top of the two movable plates 18. In the process of collecting leeks, the operator can start the electric telescopic rod 21 through the button on the operation panel according to the density of the leeks collected in the collecting bucket 14. The telescopic movement of the electric telescopic rod 21 drives the connecting rod 20 to rotate around the rotation connection point with the supporting plate 19, so that the supporting plate 19 drives the movable plate 18 to deflect around the rotating shaft 17, and adjusts the gap between the movable plate 18 and the collecting bucket 14.This can facilitate the leeks to fall into the bottom layer of the collecting bucket 14, so that the leeks are evenly piled in the collecting bucket 14, fully utilize the space of the collecting bucket 14, avoid the situation of local accumulation being too high or too low, and ensure that the harvested leeks are neatly piled in the collecting bucket 14. Finally, when it is necessary to take out the leeks inside the collecting bucket 14, the operator first manually grabs the baffle 24, pulls it out from the position in contact with the two limit blocks 26, and then rotates the baffle 24 180 degrees with the rotation connection point of the tension spring telescopic rod 23 and the mounting block 22 as the center. At this time, the cover plate 25 is no longer restricted by the baffle 24, and the operator can rotate the cover plate 25 to open the collecting bucket 14. The design of this capping mechanism is simple and convenient to operate, and can quickly open the collecting bucket 14, and conveniently and quickly take out the leeks piled inside. Compared with the complex operations such as manual handling and dumping required during traditional manual harvesting, it is more time-saving and labor-saving, and greatly improves work efficiency.

[0022] Embodiment 2: A control method for an efficient crop harvesting robot comprises the following steps: Step 1: Adjust the height of the movable baffle bar 3 and the movable center bar 5 according to the height of the crops; Step 2: Start the driving wheel 16 and the driving motor 12 to make the robot move forward and harvest crops; Step 3: adjusting the deflection angles of the two movable plates 18 according to the density of the harvested crops, and starting the conveyor belt 9 to convey the harvested crops into the collecting bucket 14; Step 4: After turning off the robot, open the cover 25 to take out the crops in the collecting bucket 14.

[0023] Working principle: First, adjust the height of the two movable baffles 3 and the movable center bar 5 according to the growth of the leek in the leek field, rotate the rotating disk 7 to drive the screw rod 6 to rotate so that the movable baffle 3 or the movable center bar 5 is lifted or lowered to the appropriate position, and then start the electric telescopic rod 10 to fine-tune the height of the cutting wheel 13 according to the needs, so that the reserved length of the root of the leek can be controlled, and then start the two driving wheels 16 and the driving motor 12 to make the robot move forward and make the cutting wheel 13 harvest the leek, the fixed baffle 2, the movable baffle 3 and the fixed center bar 4, the movable center bar 5 can divide the harvested leek into two parts, and can prevent the cut leek from falling to both sides of the robot. Under the influence of the continuous forward force of the robot, the head of the leek will fall to The conveyor belt 9 is positioned so that the conveyor belt 9 can be started to transport the leeks to the inside of the collecting bucket 14, and then roll down from the top of the two movable plates 18, and finally gather and pile up in the collecting bucket 14, so as to ensure that the harvested leeks are neatly piled. In the process of collecting leeks, the electric telescopic rod 21 can be started to drive the connecting rod 20 to rotate according to the density of the collected leeks, and then the supporting plate 19 drives the movable plate 18 to deflect to adjust the gap between the movable plate 18 and the collecting bucket 14, so that the leeks can fall into the bottom layer of the collecting bucket 14. Finally, the baffle plate 24 is pulled out from between the two limit blocks 26, and then rotated one hundred and eighty degrees to release the restriction on the cover plate 25, so that the cover plate 25 can be rotated to take out the leeks inside the collecting bucket 14, which is more time-saving and labor-saving than traditional manual harvesting.

[0024] 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.
