At present, there are thousands of drone sprayer manufacturers around the world. How can we choose? Today we introduce how to choose a drone sprayer. In general, the following issues are most noteworthy:
We need to carefully look at the parameters, make a comparison, and analyze the effect of the drone spraying before buying a drone
As drone sprayer, the most important thing is to precise spraying. What is precise spraying? in the process of plant protection, pesticides must be sprayed on the front and back of the crop leaves, and chemical must be reach to the leaves and thereby effectively killing pests.
For example, the single-rotor drone sprayer in the figure below, the airflow generated by the propeller can cause the chemical liquid to be rolled up, which may attach to the drone kit and waste.
how to ensure that pesticides are attached to the leaves? This depends on the atomization effect sprayed by the drone.
The figure above shows the adhesion effect of the spraying on the surface of crop leaves. From left to right, the atomized particles are getting larger and larger. It seen that the smaller the atomized particles, the more saved the chemical and water, the more uniform the adhesion
Generally speaking, the atomized particles can achieve better spraying effect below 250 microns.
This picture is show the chemical attached on the surface of a pest. Large particles of medicinal solution are easily gathered and lost. Only pesticides with small atomized particles can be uniformly attached to the surface of the pest, and easier to kill it.
At present, there are two kinds of spraying technology for spraying crops on the market. One is constant spraying technology and the other is variable spraying technology.
Because drones need to turn when flying in the field, the flow rate will not be adjusted automatically as the flight speed decreases with constant spraying technology, it make too much chemical applied to the crops when turn, which will make crops damage and waste.
3. Will there be duplication and omission spraying
Some crops have higher requirements for spraying pesticides, especially control chemical such as herbicides. Spraying too much can easily cause damage, if spraying less will not have an effect. duplication and omission spraying is an important aspect of considering the effects of drone sprayer.
This is duplication and omission spraying by a drone sprayer,
This is related to the flying accuracy of the drone, which is determined by the positioning and navigation system of the drone. Currently, there are three types of drone sprayer positioning and flight technologies on the market: pure manual, GPS, and RTK.
This picture compares RTK and GPS positioning technology. (The white box in the figure represents the plot, and the green line represents the actual flight path of the drone.) There is a certain error in GPS positioning. The positioning accuracy of ordinary GPS is ≥ 1 meter, but when spraying in the field, due to the positioning error, the flight path may deviate greatly (as shown on the right), causing duplication and omission spraying problems.
4. Can it suit different terrains?
Because the crops are different in height and terrain, in order to ensure the spraying effect, it is necessary to maintain a relatively constant distance between the plant protection drone and the top of the crop. Currently, drones can achieve this through ground-flighting technology.
Intelligent Agriculture is the trend of all over the world. And the intelligent drone act as a important role in this world plan.
Agriculture spraying drone can replace the traditional pesticide sprayer and it's speed is 40times of the traditional sprayer. It will save 90% water and 30%-40% pesticide. Small droplet diameter make the pesticide more well-distribute and improve the effect. At the same time, it will make the people faraway from the pesticide and reduce the pesticide remain of the crop.
