Unmanned aerial vehicle agrodrone with a hybrid power plant

Abstract

This utility model is used in agriculture for spraying plants, foliar feeding with working compounds, and applying working solutions of pesticides and mineral fertilizers. The agrodrone utilizes a quadcopter design and has a frame, a propeller assembly consisting of lithium-ion batteries and electric motors located on each folding arm, an internal combustion engine with a generator equipped with an electronic fuel injection system and a forced-air liquid cooling system, a spray system with removable liquid storage units with a total capacity of 50 liters, a hydraulic pump, water supply tubes, and nozzles that provide a fine spray of liquid fertilizers and plant protection products. Increased productivity is achieved by increasing the volume of the working fluid storage units.

Description

[0001] The utility model relates to the field of aviation, namely to unmanned aerial vehicles used in agriculture for spraying plants, foliar feeding with working preparations, as well as processing with working solutions of pesticides and mineral fertilizers.

[0002] The task, which the claimed utility model is aimed at solving, is the creation of an unmanned aerial vehicle (agrodrone), which ensures increased productivity in the processing of agricultural areas with working fluid.

[0003] The technical result is an increase in productivity due to the volume of blocks for placing the working fluid.

[0004] The specified technical result is achieved in that the unmanned aerial vehicle agrodron is made according to a quadcopter design, contains a frame, beams with electric motors and rotors mounted on them, a power supply system and a spraying system including units for working fluid, a hydraulic pump, water pipes and nozzles, while the spraying system includes two units for working fluid with a volume of 25 liters each.

[0005] The essence of the utility model is explained by the figures. Fig. 1 shows the agrodron in its unfolded (working) state.

[0006] The agrodrone is a quadcopter design of an unmanned aerial vehicle, including a frame (1), folding arms (6) with electric motors (2) and rotors (7) mounted on them, a power supply system and a spraying system (5), including units for working fluid (4), a hydraulic pump, water pipes and nozzles, an internal combustion engine with a generator (3) and batteries (not shown in the drawing).

[0007] The internal combustion engine is equipped with an electronic fuel injection system, a forced-air liquid cooling system, and an electronically controlled generator. The liquid cooling system is shown in Fig. 2, which depicts a cooling radiator (8), fans (9), and arm mounts (10). In a particular embodiment, the arms of the agrodrone can be foldable.

[0008] In a specific embodiment, the power supply system may have a hybrid configuration and include an internal combustion engine with a generator and batteries. In this embodiment, the internal combustion engine may be located at the bottom of the agrodrone frame along its central axis between the spray system's working fluid blocks. The internal combustion engine may be equipped with an electronic fuel injection system, an electronically controlled generator, and a forced-air liquid cooling system.

[0009] This technical solution can work in conditions from -10 to +40°C.

[0010] The device operates as follows. Before beginning a flight mission, the operator prepares the agrodron for operation, turns on the power supply system, and fills two working fluid tanks, each holding 25 liters, with a working solution of liquid fertilizer, plant protection products, or other working solution.

[0011] After preparing the agrodrone, the operator initiates the flight mission using the control panel. After reaching altitude, the agrodrone enters flight mode along the preset route and begins cultivating the agricultural area.

[0012] During flight, the hydraulic pump delivers working fluid from the working fluid blocks through the water supply pipes to the nozzles. The nozzles spray the working fluid over the area being treated.

[0013] The presence of two working fluid units in the spraying system, each with a capacity of 25 liters, allows for an increase in the volume of working fluid placed on board the agrodrone, thereby increasing the productivity of the agrodrone when processing agricultural areas.

Claims

An unmanned aerial vehicle (agrodrone), constructed using a quadcopter design, comprising a frame, arms with electric motors and rotors mounted thereon, a power supply system, and a spraying system including units for working fluid, a hydraulic pump, water pipes, and nozzles, characterized in that the spraying system includes two units for working fluid with a capacity of 25 liters each.
