DESC:FIELD OF INVENTION

[001] The present invention provides open field spray system using aerial vehicles.

[002] Particularly the invention provides an alternate approach for open field spray using drone or micro aerial vehicles with tethered technique to keep longer flight time and increased coverage area with multiple.

[003] More particularly the invention provides a faster coverage of spray for larger areas without much downtime and more aerial vehicles operating simultaneously with less operators.

BACKGROUND OF INVENTION

[004] Use of aerial vehicles or commonly called as drones are used in agriculture spray and other operations increasingly due to increased labor cost and non availability of labor on time. Drones and particularly Hex copters and Octo copters are currently used and only showcased as a potential candidate for performing spray operations in open field farms where the crops such as paddy, wheat, maize, cotton and many other types are grown in open fields. The primary limitation of the drone is low load carrying capacity and thereby less flight time. Effectively the operation to happen at least 8-10 hours a day it is economically difficult to operate.

OBJECTIVES

[005] Principal objective of the present invention is to provide open field spray system using aerial vehicles.

[006] Another objective is to provide a comprehensive system of aerial vehicles that can work cooperatively much longer by using tethered power and liquid for open field crops.

[007] Still another objective is to provide an operationally feasible solution using drones for performing spray operation in open field crops using a system of aerial vehicles with less operators.

[008] Another objective of the invention is to provide aerial vehicles able to perform for large fields on a single day by using plurality of drones that need not land and take off often for battery and payload mounting.

SUMMARY OF INVENTION

[011] According to the main aspect of the invention there is provided open field spray system using aerial vehicles which system comprises floating balloon (101), the balloon being anchored to a platform (102) , aerial vehicles (103) being connected to platform (102) by fluid transfer means (104) , the said balloon (101) being anchored to the ground by means (105), (106) is a power supply feeding power to aerial vehicles (103), the said drones being controlled by radio transmitter (108) by operator (109).
.
[012] According to yet another aspect of the invention wherein there is no man power coming in contact with the pesticides that are sprayed.

DETAILED DESCRIPTION

[013] The workings of the system is described as a preferred embodiment with reference to Fig 1.Operator(109) scans the area and first anchor the balloon (101) or the larger flying vehicle(101) at a specific location of farm (107). Once the area is selected , the balloon (101) is anchored firmly to the ground. The platform(102) of the balloon(101) holds the cables and liquid pipes (105 , 104) so that the drones(103) that are performing the work need not always hold that payload throughout the time of operation. The current payload will be a small portion of the pipe(104) that is acting on the drones(103) instead of a large payload of liquid pipes and the problem of collision with the crops. The drones are being assigned an area within the land(107).

[014] As a preferred case the balloon is anchored in the center of a 1 acre land. This means that operator(109) would assign one each drone to 0.25 acre and 4 drones(103) would complete the job for 1 acre land (107). The significant advantage is that more drones(103) would operate for given area and complete the job in a shorter time.

[015] The power supply and liquid supply unit(106) can be placed in a more accessible position and cables can be run. This unit(106) can be moved when the unit moves to the new location along with the balloon.

[016] Using the exemplary multirotor aerial vehicle along with a balloon or a centralized flying mechanism that stays as master drone or aerial vehicle to uphold the tethered objects away from crops and other hindrances on the ground and providing continuous power and liquid to the drones as opposed to the current drones that could fly autonomously but with limited time and liquid.

[017] The spraying liquid weight is sufficient to bear with the small drones(103). In order to share the liquid and electric cable weight and not to touch the crops on the ground, the balloon or a another flying object is very important to resolve the challenges in the open field spray operation.

[018] In a preferred embodiment acres and acres of area (107) can be covered without having the drones to be grounded when the balloon(101) and the ground unit (106) can move across the field.

[019] The spraying liquid could be any liquid required in the agriculture like water or pesticide or
