The article begins with an emphasis: plant protection is risky, choose carefully! It is not recommended that private individuals without drone experience assemble plant protection drones on their own. Assembling a drone requires three points of skill and seven points of care, welding and debugging are the two main points, and you need to have enough skill and care before you can achieve the right result. We hope that all of you will get this secret book and practice it carefully, so that you will be able to assemble the drone as soon as possible.
1、Material preparation
Material list:
1. Frame: EFT 6-axis 10kg frame
2. Power system: 6 8010 motors, 80A ESC, 3 pairs of 24-inch folding paddles.
3. Spray system: 1 water pump, 1 ESC, 4 pressure nozzles, water pipes and adapters
4. Flight control: DJI A3 (mounting reference)
5. Plug accessories: AS150 anti-ignition male red and black 2 pairs, XT90 male 6, XT60 male and female head 1 pair, 4.0mm banana head male and female 18 pairs, 5mm heat-shrinkable tubing 1 meter, 10mm heat-shrinkable tubing 1 meter, 8mm snakeskin mesh tube 4 meters
6. Tools: a set of hexagonal screwdriver, more than 150W soldering station 1, 1 hot air gun
2、Installation of the rack
Rack factory are modular, has completed most of the internal assembly, so the overall installation is relatively simple, the factory comes with a manual, you can refer to the instructions for assembly.
One of the things to note is that, before installing the rack, it is recommended to weld the power cord plug at the bottom of the center board before the next step in the installation, so as not to facilitate the assembly of the whole machine is not easy to weld the plug at the bottom.
Motor and ESC pre-processing
As shown in the above figure the whole machine assembly before the main power plug welding and then subsequent assembly of the rack, the installation process is detailed in the following figure:
ESC end female connector
Motor end male connector
ESC welded plug, cut a section of snakeskin mesh tube will be ESC out of the line sleeve sealed up, and at both ends of the snakeskin mesh tube using 10mm heat-shrinkable tubing shrinkage to avoid bifurcation of the two ends of the snakeskin mesh tube, after the completion of the process is shown in the figure below:
Process the 6 motors and ESCs in turn.
3、install the motor ESC
Motor ESC can be installed into the body after processing, the frame uses a quick release side plate, install ESC will be the side of the four screws unscrewed, remove the side plate, and then the ESC from the side of the body into the side, and then the side plate hollow slot embedded in the ESC fan hot plate re-installed can be used, the power end of the ESC XT90 inserted in the center of the power board of the female end of the control appeared to be the end of the machine through the arm extends to the bottom of the motor base and motor Connected.
Remove the side panel and put in the ESC
ESC heatsink embedded in side panel slot reattached to body
Outlet wire through the arm
ESC out to motor out.
Solder the step-down ESC output port to an XT60 female adapter plate and the step-down ESC input to an XT60 male connector, as shown below
Soldered XT60 female adapter plate
Note that the red wire in the middle of the signal wire of the step-down ESC is recommended to be cut off.
ESC three terminal wires are processed
Attach the adapter plate for the ESC outputs to the side holes in the body panel via nylon posts.
Fixed after the ESC control output can be exposed to a section in the panel outside, the above control part of the installation is complete.
Then install the water pump, water pipe, nozzle spray part, refer to the following figure, the water pump will be installed to the bottom of the water tank.
Cut the hose to the proper length for installation.
Extend and solder an XT60 male connector from the pump outlet to the pump controller output at the bottom of the panel.
A two-part adapter at the top of the stand divides the water hose into two directions.
The water hose extends down the bottom of the arm and under the motor mount, and the water hose can be secured to the arm either with a tie wrap or a more attractive hose clamp (sold separately).
The nozzle section is fitted to the mounting plate on the bottom of the motor base, tightened using a nut, and finally the base plate is brought up to the bottom of the motor base.
It is recommended here not to tighten the bottom cover screws until the motor steering has been tested to avoid the need for repeated disassembly during commissioning.
4、Installation of flight control
Flight control we choose DJI A3-AG and Datalink-3 remote control as a reference for installation, detailed wiring and instructions for use refer to the official manual of DJI!
After installation, it is recommended to apply hot melt glue to the signal cable plug to prevent it from coming loose.
The Datalink-3 remote control has a very long antenna extension and the end antenna portion is flat, so you can DIY your own mounting plate to fix the antenna vertically on both sides of the stand when installing it.
5、Power on debugging
After installing the flight control, carefully check whether each line is connected correctly, especially pay attention to whether the positive and negative poles are reversed, whether the signal line and the negative pole are reversed, and whether each socket of the flight control is a corresponding module. After checking whether there is no error, you can power on the debugging.
Debugging is divided into several points
The main power supply has two sets of plugs on the left and right sides, when the power is connected to the right side of the negative pole and then the right side of the positive pole, and then connect the left side of the negative pole and the left side of the positive pole.
Power on momentarily check whether there is any abnormality, whether the indicator light of each module is normal, whether there is any module heating abnormality, confirm that each module works normally before entering the next step
Remote control and flight control setup, refer to the manual of the flight control and remote control to setup, map the remote control channel, check the forward and reverse direction, and set the basic parameters of the flight control.
Calibrate the ESC, for ordinary ESCs, make sure to calibrate the travel before flight, for DJI ESCs and some fixed travel ESCs that can't be calibrated, you can skip this step.
Check and adjust the motor forward and reverse, if the flight control support software test motor through the software test, common flight control, such as DJI, Top Attack, etc., if it does not support by unlocking the view, such as the extreme flight flight control, check if you find that there is motor steering is not correct, through any of the two motors can be reversed by any adjustments to the motor plugs!
After the debugging is completed, you can install the nozzle, bottom cover and paddles in order. Use a leveling tape or leveling bubble to correct the level of the motor
Complete installation of the whole machine is completed
