[0030] As Figures 1-6 shown, the present embodiment proposes an agricultural unmanned automatic control device, which comprises a controller 1, a control rod and two groups of signal receiving rods 2, one group of signal amplification ring groups 3 is arranged at the outer end of each of the two groups of signal receiving rods 2, a left push rod group 4 and a right push rod group 5 are arranged at the two ends of each of the two groups of signal amplification ring groups 3, a linkage push rod 6 is arranged at the lower end of each of the left push rod group 4 and the right push rod group 5, a left push groove 7 and a right push groove 8 are arranged at the outer end of the linkage push rod 6, a threaded rod 9 and a linkage motor 10 are arranged at the center of the linkage push rod 6, and the linkage motor 10 is connected with a control module.

[0031] The signal amplification ring group 3 is made of metal material with strong conductivity, each signal amplification ring group 3 includes multiple groups of stacked signal rings, and the two ends of the uppermost group of signal rings are movably connected with the left push rod group 4 and the right push rod group 5 respectively.

[0032] The signal amplification ring group 3 is made of metal material with strong conductivity, which can effectively enhance the signal receiving and transmission capability, improve the capture and transmission efficiency of the device for the unmanned aerial vehicle signal, reduce the signal attenuation and interference, and improve the stability of the unmanned aerial vehicle control.

[0033] Each signal amplification ring group 3 is composed of multiple groups of stacked signal rings, which increases the area and dimension of signal receiving and transmission, further optimizing the signal processing effect.

[0034] The uppermost group of signal rings is movably connected with the left push rod group 4 and the right push rod group 5, which provides a structural basis for subsequent control of the action of the signal amplification ring group 3 by the push rod group, realizing the flexible deformation of the signal amplification ring group 3

[0035] The lower ends of the left push rod group 4 and the right push rod group 5 are fixedly connected with the linkage push rod 6, and the two linkage push rods 6 slide up and down along the left push groove 7 and the right push groove 8 respectively.

[0036] The left push rod group 4 and the right push rod group 5 are fixedly connected with the linkage push rod 6, and the linkage push rod 6 can slide up and down along the left push groove 7 and the right push groove 8, which ensures the stability and accuracy of transmission between components, so that the action of the signal amplification ring group 3 can accurately change with the movement of the linkage push rod 6, ensuring reliable operation of the device.

[0037] The central part of the two linkage push rods 6 is provided with a threaded groove between the threaded rod 9, the threaded groove is wrapped around the outer end of the threaded rod 9, and the lower end of the threaded rod 9 is movably connected with the linkage motor 10.

[0038] The linkage push rod 6 cooperates with the threaded rod 9 through the threaded groove, and the lower end of the threaded rod 9 is movably connected with the linkage motor 10, which can stably convert the rotary motion of the linkage motor 10 into the linear motion of the linkage push rod 6, realizing accurate position control, so as to accurately control the expansion and contraction action of the signal amplification ring group 3.

[0039] The linkage motor 10 is signal connected between the control module and the control rod.

[0040] The linkage motor 10 is signal connected with the control rod through the control module, which establishes a way for the operator to remotely control the action of the linkage motor 10 through the control rod, and further realizes remote control of the action of the signal amplification ring group 3 in the whole device, which is convenient and fast, and improves the operability of the device.

[0041] The control module comprises a first signal transmission unit at the end of the control rod and a second signal transmission unit at the end of the linkage motor 10, the first signal transmission unit is used for transmitting the forward and backward movement instruction of the unmanned aerial vehicle controlled by the control rod, and the second signal transmission unit is used for receiving the forward and backward movement instruction.

[0042] The control of the linkage motor 10 is realized through the control signal transmission, and then the form of the signal amplification ring group 3 is adjusted in real time according to the movement state of the unmanned aerial vehicle. When the unmanned aerial vehicle moves forward, the signal amplification ring group 3 expands outward to form a horn shape, the signal receiving and transmission range is expanded, and the risk of interference is reduced. When the unmanned aerial vehicle moves backward, the signal amplification ring group 3 is retracted and attached to the controller 1. This follow-up control mode can dynamically adjust the signal processing area according to the actual demand, and ensure that the signal transmission remains stable during the driving of the unmanned aerial vehicle.

[0043] The control module is the core part of signal transmission and action control of the whole unmanned agricultural automatic control device, and the working process is as follows:

[0044] When the operator operates the control rod to control the unmanned aerial vehicle to move forward, the electronic elements in the control rod will generate corresponding electric signals. The electric signals are acquired by the first signal transmission unit and are encoded. The first signal transmission unit converts the electric signals representing the forward movement instruction into a format suitable for wireless transmission, and emits electromagnetic waves of a specific frequency into the air;

[0045] The second signal transmission unit at the end of the linkage motor 10 is equipped with a special receiver for receiving the electromagnetic wave signals emitted from the first signal transmission unit. After receiving the signals, the second signal transmission unit first decodes the signals and restores them to the original control instruction electric signals. After a series of signal amplification and filtering processing to remove possible noise interference, the second signal transmission unit transmits the processed forward movement instruction electric signals to the drive circuit of the linkage motor 10;

[0046] After receiving the instruction signals, the drive circuit of the linkage motor 10 drives the linkage motor 10 to rotate in the predetermined direction. The rotation of the linkage motor 10 drives the threaded rod 9 connected thereto to rotate synchronously. Since the linkage push rod 6 is matched with the threaded rod 9 through the thread groove, the rotation of the threaded rod 9 makes the linkage push rod 6 move upward along the left push groove 7 and the right push groove 8. The upward movement of the linkage push rod 6 drives the left push rod group 4 and the right push rod group 5 to move outward through the fixed connection relationship, and finally makes the signal amplification ring group 3 expand outward to form a horn shape. Such a change in form can increase the effective area of signal reception and transmission, improve the ability of capturing and transmitting signals of the unmanned aerial vehicle, reduce the influence of external interference on signal transmission, and ensure that the unmanned aerial vehicle can accurately receive the control signals and fly forward according to the instructions;

[0047] When the operator operates the control lever to control the unmanned aerial vehicle to move backward, the control lever generates an electric signal of moving backward, which is also acquired, encoded and emitted in the form of electromagnetic wave by the first signal transmission unit, and after the second signal transmission unit receives, decodes and processes the signal, the signal transmission unit transmits the electric signal of moving backward to the drive circuit of the linkage motor 10, the drive circuit drives the linkage motor 10 to rotate reversely, drives the threaded rod 9 to rotate reversely, moves the linkage push rod 6 along the left push groove 7 and the right push groove 8 downward, and then moves the left push rod group 4 and the right push rod group 5 inward, and the signal amplification ring group 3 is retracted, and finally a plane is formed and attached to the outer surface of the upper end of the controller 1.

[0048] During the whole process, the control module can accurately convert the operation instruction of the control lever into the action of the linkage motor 10, and then accurately control the shape of the signal amplification ring group 3, and can accurately control the expansion angle and range of the signal amplification ring group 3 according to the proportion of the forward and backward movement of the control lever, and always keep the signal transmission stable during the driving of the unmanned aerial vehicle, and provide reliable signal protection for the unmanned driving of the agricultural machine.

[0049] In use, the control lever controls the forward and backward movement of the unmanned aerial vehicle, drives the first signal transmission unit to transmit the forward and backward movement signal to the second signal transmission unit, when the second signal transmission unit transmits the forward signal, the linkage motor 10 drives the threaded rod 9 to rotate, drives the linkage push rod 6 to move upward along the left push groove 7 and the right push groove 8, drives the left push rod group 4 and the right push rod group 5 to move outward, drives the signal amplification ring group 3 to expand outward to form a horn shape, and is used for receiving and transmitting signals to the unmanned aerial vehicle to reduce the risk of interference of the unmanned aerial vehicle, when the first signal transmission unit transmits the backward signal, the linkage motor 10 drives the threaded rod 9 to rotate, drives the linkage push rod 6 to move downward along the left push groove 7 and the right push groove 8, drives the left push rod group 4 and the right push rod group 5 to move inward, and drives the signal amplification ring group 3 to retract, and finally a plane is formed and attached to the outer surface of the upper end of the controller 1, when the distance of the unmanned aerial vehicle is changed, the expansion angle and range of the signal amplification ring group 3 can be controlled according to the proportion of the forward and backward movement, and the signal transmission is stable during the driving of the unmanned aerial vehicle.
