[0021] The technical terms in the embodiments are described as follows:
[0022] The steering engine, also known as the servo motor, is a kind of position (angle) servo driver. The following is a detailed explanation of the function and principle of the steering engine:
[0023] I. Function of steering engine
[0024] The main function of the steering engine is to control the angle or position of an object, and its application is very wide, including but not limited to the following aspects:
[0025] Ship steering: In a ship, the steering engine is a key device for steering the ship. It changes the deflection angle of the rudder according to the intention of the driver or the automatically designed route map, so that the ship maintains or dynamically changes the direction of navigation, ensuring the safety of the ship to the destination.
[0026] Robot joint driving: In the field of robots, the steering engine is often used to control the joints of the robot, such as arms, legs, etc., to realize various actions and movements of the robot. For example, restaurant service robots, hotel service robots, etc., use the steering engine to control their moving platforms and mechanical arms to realize autonomous navigation and object carrying functions.
[0027] Model control: In remote-controlled models such as model airplanes and model cars, the steering engine is used to control the moving parts of the model, such as wings and wheels, to control the flight direction, height and speed of the model, etc.
[0028] Smart Home: In the field of smart home, the steering wheel is often used to control the movement of household devices such as curtains, clotheslines, doors and windows, realizing intelligent home control. For example, by connecting to a smart home system, users can control the rotation of the steering wheel through a mobile phone APP or voice command, thereby realizing automatic opening and closing of curtains, lifting of clotheslines, and opening and closing of doors and windows.
[0029] Photography Gimbal: In the photography gimbal, the steering wheel is used to control the angle of the gimbal, realizing stable shooting and precise composition of the camera.

[0031] In addition, the steering wheel is also widely used in toys, education and other fields, bringing more convenience and fun to people's life and learning.
[0032] II. Principle of Steering Wheel
[0033] The working principle of the steering wheel is relatively complex, but it can be summarized as follows:
[0034] Signal reception and conversion: The control circuit receives the control signal from the signal source, usually a PWM (Pulse Width Modulation) signal with a period of 20 milliseconds. The pulse width of this signal is between 0.5 and 2.5 milliseconds, and the corresponding linear rotation angle is 0° to 180° (or 0° to 360°, depending on the type of steering wheel).
[0035] Motor drive: The control circuit converts the received PWM signal into a current signal to drive the motor to rotate. The motor drives the output shaft to rotate through a reduction gear set, thereby controlling the position of the steering wheel.
[0036] Position feedback and closed-loop control: The position sensor (such as a potentiometer) detects the position of the output shaft and feeds it back to the control circuit. The control circuit compares the feedback signal with the set value and adjusts the rotation direction and speed of the motor to achieve precise position control. This closed-loop control system ensures the high precision and stability of the steering wheel.
[0037] In summary, the steering wheel realizes precise position control by receiving control signals, driving the motor to rotate, detecting position feedback and adjusting the motor rotation. Its high precision, fast response and large torque make it widely used in various fields.
[0038] Microcontroller: A microcontroller is a single-chip microcomputer that integrates the main parts of a microcomputer on a chip, also known as a microcontroller unit (MCU). Here is a detailed introduction to the microcontroller:

The rack 1 is an H-shaped frame including two square steel pipes and a circular pipe, which are fixedly connected by welding to ensure the strength. The rotating shaft 2 is rotatably connected to the square steel pipe through a bearing.
[0046] Through the driving cooperation of the driving device and the transmission assembly, the two rotating shafts 2 rotate synchronously. The rotating shaft 2 drives the barrels 7 on both sides of the rack 1 to alternately insert into the ground. The seedlings are guided into the opening and closing mechanism by the barrel 7. When the opening and closing mechanism is inserted into the soil, the opening and closing mechanism is opened. The seedlings in the barrel 7 smoothly slide out of the opening and closing mechanism and enter the soil. Under the driving of the rotating shaft 2, the opening and closing mechanism is automatically closed.
[0047] The utility model has the advantages of simple structure, high efficiency, low manufacturing and maintenance cost, and greatly saves manpower and time cost.
[0048] Furthermore, both ends of the rotating shaft 2 are connected to one end of a connecting plate 4, and the two connecting plates 4 and the rotating shaft 2 are arranged in a Z-shaped structure. The other end of the connecting plate 4 is vertically connected to a connecting shaft 5, and the end of the connecting shaft 5 is rotatably connected to the barrel 7.
[0049] Specifically, a side plate 6 is welded to the barrel 7 , and the connecting shaft 5 is rotatably connected to the side plate 6 .
[0050] The two connecting plates 4 and the rotating shaft 2 are arranged in a Z-shaped structure, so that the two barrels 7 are alternately inserted into the soil, thereby improving the transplanting efficiency.
[0051] Furthermore, the transmission assembly includes sprocket 1 18 and sprocket 2 19 fixedly connected to a rotating shaft 2, and sprocket 3 20 fixedly connected to another rotating shaft 2. Sprocket 2 19 is coupled to sprocket 3 20 through a chain, and sprocket 1 18 is coupled to the driving device through a chain.
[0052] In this embodiment, sprocket 1 18 , sprocket 2 19 , and sprocket 3 20 all have 13 teeth, and the chain is type 05B with a pitch of 8 mm. The tension they withstand is sufficient to drive the movement of the barrel 7 .
[0053] The fuel engine on the tractor drives the sprocket 18 and the rotating shaft 2 to rotate through a chain. The rotating rotating shaft 2 drives the sprocket 2 19 to rotate, and through the chain transmission, drives the sprocket 3 20 to rotate, thereby realizing the synchronous rotation of the two rotating shafts 2. The two connecting plates 4 are arranged in a Z-shaped structure with the rotating shaft 2, thereby driving the two barrels 7 to be alternately inserted into the soil.
[0054] Furthermore, the opening and closing mechanism includes two semi-conical cylinders 9, which are hinged to the barrel 7 through a fixed rod 8. A gap is provided between the semi-conical cylinders 9 and the barrel 7. The barrel 7 is provided with a push-pull mechanism and a driving member for opening and closing the two semi-conical cylinders 9. The driving member is coordinated with the push-pull mechanism. Two sensors 21 are provided at one end of the frame 1 away from the semi-conical cylinders 9. The two sensors 21 are arranged in a one-to-one correspondence with the two barrels 7. A microcontroller is provided on the frame 1, and the sensor 21 and the driving member are electrically connected to the microcontroller.
[0055] In this embodiment, the model of the microcontroller is STM32F103C8T6; the sensor 21 is an E3F-DS100C4 photoelectric sensor, and the monitoring direction of the sensor 21 is toward the barrel 7 .
[0056] The two half-cone cylinders 9 are formed into a cone cylinder in the closed state, facilitating the sharp part to pierce the soil and reducing power loss, and guiding the seedlings in the material cylinder 7 to the sharp part, having better directivity. The two half-cone cylinders 9 are folded and separated through the reciprocating movement of the driving and pulling mechanism driven by the driving member. It should be noted that the joint between the half-cone cylinder 9 and the material cylinder 7 has a certain gap to prevent interference between the half-cone cylinder 9 and the material cylinder 7 during rotation, and the half-cone cylinder 9 does not need to rotate too much. The gap between the two half-cone cylinders 9 is sufficient for the seedlings to slide out.
[0057] The sensor 21 monitors the movement of the material cylinder 7. When the material cylinder 7 moves close to the top end of the rack 1, the sensor 21 detects that the material cylinder 7 on the same side approaches the highest point, sends a signal to the microcontroller, and the microcontroller controls the driving member on the other side to start driving the pushing and pulling mechanism to operate, thereby separating the two half-cone cylinders 9 to meet the seedlings sliding out and contacting the soil. Subsequently, the material cylinder 7 is separated from the soil, and the soil covers the roots of the seedlings. The microcontroller controls the driving member to drive the pushing and pulling mechanism to move in the opposite direction, closing the two half-cone cylinders 9.
[0058] Further, the pushing and pulling mechanism includes a side plate 6 fixedly connected to the material cylinder 7. One end of the side plate 6 close to the half-cone cylinder 9 is rotatably connected to a rotating shaft 14. The two ends of the rotating shaft 14 are fixedly connected to one end of a connecting rod 13. The two connecting rods 13 are symmetrically arranged on the two sides of the side plate 6. The other end of the connecting rod 13 is hingedly connected to a driven rod 12 and a driving rod 15. The driving rod 15 is in transmission cooperation with the driving member. One end of the half-cone cylinder 9 close to the fixed rod 8 is connected to a sliding rod 10. The sliding rod 10 is slidingly and limitingly connected to a sliding ring 11. The driven rod 12 is fixedly connected to the sliding ring 11.
[0059] Further, the driving member is a rudder 17. The output end of the rudder 17 is connected to a rudder arm 16. The driving rod 15 and the rudder arm 16 are hingedly connected to each other.
[0060] In this embodiment, the rudder 17 is selected to have a model of RB-150MG.
[0061] The rudder 17 drives the rudder arm 16 to rotate by a certain angle. The rudder arm 16 pulls the driving rod 15, the driving rod 15 pulls the connecting rod 13, the connecting rod 13 drives the rotating shaft 14 to rotate, and the driven rod 12 pulls the sliding ring 11 to slide on the sliding rod 10 and pull the two half-cone cylinders 9 to open and close by a small angle to meet the seedlings sliding out. It should be noted that the hole on the sliding ring 11 is a long waist hole to avoid the sliding ring 11 being stuck on the sliding rod 10 when pulled by the driven rod 12.
[0062] The automatic transplanting mechanism provided by the present invention has the following working principles: when in use, the frame 1 is fixedly installed on the bottom of the tractor, the sprocket 18 is connected to the sprocket on the fuel engine on the tractor through a chain, the travel speed of the tractor is controlled, and the automatic seedling feeding device installed on the tractor is used to feed the seedlings into the two barrels 7 respectively, the fuel engine on the tractor drives the sprocket 18 and the rotating shaft 2 to rotate through the chain, the rotating rotating shaft 2 drives the sprocket 2 19 to rotate, and the chain transmission drives the sprocket 3 20 to rotate, thereby realizing the synchronous rotation of the two rotating shafts 2, and the two connecting plates 4 are arranged in a Z-shaped structure with the rotating shaft 2, thereby driving the two barrels 7 to be alternately inserted into the soil, and when the sensor 21 detects that the barrel 7 on the same side moves close to the top of the frame 1, the barrel on the other side is moved. The barrel 7 is at the lowest point, and the sensor 21 sends a signal to the microcontroller. The microcontroller controls the servo 17 on the other side of the barrel 7 to start running. The servo 17 drives the servo arm 16 to rotate a certain angle. The servo arm 16 pulls the driving rod 15, and the driving rod 15 pulls the connecting rod 13. The connecting rod 13 drives the rotating shaft 14 to rotate and pulls the driven rod 12 at the same time. The driven rod 12 pulls the slip ring 11 to slide on the slide rod 10 and pulls the two half-conical barrels 9 to open and close at a small angle. The seedlings slide out from the gap between the two half-conical barrels 9, and then the barrel 7 is separated from the soil. The soil covers the roots of the seedlings. The microcontroller controls the servo arm 16 to rotate in the opposite direction to close the two half-conical barrels 9. The automatic seedling feeding device pushes the next seedling into the barrel 7. The two transplanting assemblies repeat the above actions alternately to realize automatic transplanting operations.
