Quan Xing.
Using rugby shape structure (laterally disposed) mixing chamber 1 when, it is preferable that medicine fertilizer import 3 be arranged in central cavity
The maximum position of diameter, mix plate 8 and be arranged at a quarter for mixing chamber 1, that is, can guarantee the mixability that mixes for the first time,
Guarantee secondary mixed mixability again, so that mixed effect reaches best.
In a kind of preferred embodiment of the present invention, before carrying out spraying operation, start PLC controller and location sensitive first
Device obtains the crop total quantity and average plant size in crop field to be sprayed by row, calculates total medicine that entire crop field sprays needs
Amount and total Water, while calculating the amount of spraying that is averaged of every plant.
When being sprayed, according to the real-time plant size information that position sensor incudes, spraying for every plant is adjusted
Amount, so that the amount of spraying in entire crop field will not be too little or too much, simultaneously, it is ensured that the uniformity sprayed to entire field crop.
The foregoing is merely presently preferred embodiments of the present invention, practical range not for the purpose of limiting the invention；If do not taken off
It from the spirit and scope of the present invention, modifies or equivalently replaces the present invention, should all cover in the claims in the present invention
In protection scope.
