Description
BACKGROUND OF THE
A helicopter is an aircraft with lift and propulsive force generated by turning a rotating wing, called a rotor, to the engine. Vertical takeoff and landing and air stopping are possible, and the rotary wing controls the angle so that it can move forward, backward, and horizontally.
Helicopters are available for a variety of purposes such as police service, lifeguarding, fire suppression, aerial photographing, and the ability to take off and land on a small area, fly at slow speed along complicated terrain, and stay in one place. In addition, a helicopter may be used without aerial photographing, pesticide spraying, or the like, without user's direct boarding.
However, since the conventional helicopter is composed of the main rotor and the sub rotor two wings, even if a single wing is damaged or obstructed, the unmanned helicopter crashes, and at the same time, the side is gentle and flat, I have a problem.
Recently, a multi-copter with a number of electric motors and propellers has been developed that uses a battery to operate as an electric motor. The multi-copter is a type of helicopter capable of vertical takeoff and landing, . Most multicopers have an even number of rotor blades in the form of two pairs (quadrupole copter, X copter), three pairs (hexacopter, Y-6) and four pairs (octocopter) In the case of -6, it is placed on the two lower planes. However, the multi - copter has a limited take - off load due to the use of electricity from the battery, which limits the flight time.
In addition to the main power source of helicopter, agricultural power source is needed to spray pesticide. In order to load pesticide and agricultural water, large capacity battery is needed. However, large-capacity batteries are very expensive and heavy, which makes it difficult to mount them on unmanned helicopters.
As a conventional technique,
SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned needs, and it is an object of the present invention to provide a multi-copter which can operate with a battery and an electric motor, And a vertical take-off and landing aircraft for agricultural use having an engine and a propeller.
According to another aspect of the present invention, there is provided an agricultural lifting / unloading vertical take-off and landing machine for agricultural use including a body part, a control part coupled to the body part, A propulsion unit coupled to the other end of the frame and driven by receiving signals from the control unit and a propeller coupled to one end of the engine and rotated by the engine to generate a thrust in a vertical direction, A fuel supply unit which is composed of a fuel tank installed in the body and a fuel line fixed to the frame and supplying fuel to each engine, and an agrochemical spraying unit installed in the body and spraying agrochemicals .
According to an embodiment of the present invention, the controller controls a throttle valve that controls a fuel injection amount of the engine to control a rotational speed of the propeller, thereby controlling a posture and a thrust of the vertical take-off and landing device.
In one embodiment of the present invention, the propulsion unit is characterized in that the propeller rotating in the clockwise direction and the propeller rotating in the counterclockwise direction are paired.
According to an embodiment of the present invention, the pesticide spraying unit includes a battery installed in the body, a medicine pail, and a DC pump for supplying the medicine to the spraying nozzle in the medicine pail.
In an embodiment of the present invention, the remote control and remote control may be performed by remote control of the unmanned control vertical take-off and landing device, and GPS for confirming the position of the unmanned control vertical take-off and landing device and transmitting it to the control unit .
In one embodiment of the present invention, the propulsion unit includes a starter connected to the engine shaft in the opposite direction to which the propeller is connected, and the control unit receives a start signal from the remote controller and transmits a current signal to the starter And the engine is activated by an electric motor of the starter.
The present invention has a large maximum load and a long flying time as compared with a multi-copter in which a fuel cell is disposed at the center and a plurality of engines and a propeller are used for a battery and an electric motor.
In addition, it is equipped with a large number of propellers, and has high stability.
