Multipurpose agricultural remote driving vehicle {MULTI-PURPOSE AGRICULTURAL REMOTE DRIVING VEHICLE}

The disclosed content relates to a multi-purpose agricultural remote driving vehicle capable of attaching and detaching various devices by forming a coupling part on a vehicle body, and performing various tasks such as remotely driving, adjusting the left and right turning angle of a front vehicle body, transporting, and spraying chemicals.

Unless otherwise indicated herein, material described in this section is not prior art to the claims in this application, and it is not admitted that the material described in this section is prior art.

In general, when harvesting crops in a greenhouse or field, a motorized small work vehicle or battery-equipped electric vehicle that can be moved back and forth to eliminate the inconvenience of manually transporting the harvested crops to a location accessible to a cultivator or tractor Work vehicles have been developed, but such work vehicles require a lot of work time because crops are harvested and workers directly drive the work vehicle to load and transport the harvested crops on the vehicle.

If the number of workers is sufficient, if the driver and the harvester share the work, the work can be carried out efficiently with the existing work vehicle. In order to solve the problem, a conventionally remotely driven remote transport vehicle capable of transporting goods has been developed.

In addition, most of the cases where work in a room such as a plastic greenhouse is usually solved by manpower due to the nature of the space, but due to the nature of the work in an enclosed space, it is inevitable to cause damage to the health of the worker.

In spraying pesticides indoors, it is possible to grow crops using sprinklers or smart farm technology using mechanical power, but the price of devices for these mechanical power and technology is very expensive, so most farms use hand-operated sprayers will do In the work using such a manual sprayer, pesticides are sprayed using a small power sprayer and a mister while carrying a heavy liquid container on their back. There is a problem that the phenomenon of inhalation into the body cannot prevent pesticide damage.

In addition, since the above method requires a large number of workers to carry a long hose on both sides and spray the pesticide, a large number of people are required, the work time is long, the fatigue of the worker increases, and the risk of poisoning due to exposure to a large amount of pesticide This causes problems in the health and safety of workers, and in order to solve the above problems, a remote spraying vehicle capable of spraying a chemical liquid by being remotely driven has been developed.

As an example of such a remote transport vehicle, Korean Patent Registration No. 10-1004608 (published on December 28, 2010) relates to an unmanned electric transport vehicle and its control method, which includes a carrying handle, a loading box for loading objects, and a lower loading box. A vehicle body including installed wheels, a driving unit for driving the wheels using one or more electric motors, a steering unit for varying the moving direction of the electric transport vehicle, a power supply unit for supplying power to the electric motors, , a control unit for controlling driving and steering of the electric transport vehicle, and a control unit for instructing the vehicle to move forward, backward, turn left, turn right, or stop the vehicle, wherein the electric transport vehicle includes a human body detection sensor, microwave A sensor unit including a Doppler sensor, an ultrasonic sensor, and an infrared light sensor is provided so that the operator does not directly drive the electric guided vehicle or the electric guided vehicle does not move along a predetermined path, and the sensor unit directly detects the operator's motion. An unmanned electric transport vehicle capable of remotely driving is disclosed.

In addition, Korean Patent Publication No. 10-2013-0011166 (published on January 30, 2013) relates to a wireless control pesticide sprayer that sprays pesticides while manipulating the moving direction to a place where crops are located through wireless remote control. A remote controller for generating a remote driving control signal to spray the pesticide through the pesticide sprayer; A body portion equipped with a transceiver, a control box, a power supply unit, and a motor; A nozzle installed on the side of the body to spray pesticides; a moving member moved by the driving of the motor so that the body portion is moved in the forward and backward directions; A sensor unit that allows the pesticide sprayer to move along a line with crops; A hose reel in which a hose connected to the pesticide reservoir is wound so as to supply pesticide to the nozzle; and a surveillance camera that monitors the spraying of pesticides on crops, which makes it easy to spray pesticides with a small number of people in an effortless state and prevents workers from being poisoned by pesticides, thereby contributing to health and safety. Disclosed is a wireless control pesticide sprayer that provides excellent effects even in

In addition, in Korean Patent Registration No. 10-1460991 (published on November 21, 2014), an unmanned pest control vehicle is installed in the valley between the ridges formed on the ground in the house facility and enables simultaneous driving in the open field, thereby enabling the driving rail While carrying out operations such as spraying chemicals and/or transporting cultivated crops after harvesting while moving along, the transport operation after harvesting of the cultivated crops is not interrupted even after leaving the driving rail, and the transport operation to the destination outside the facility is continuously carried out Disclosed is a multi-purpose unmanned control vehicle that enables

However, in the case of the unmanned electric transport vehicle as described above, it is composed of a loading box on the upper part of the body part, and as the operator drives the electric transport vehicle directly or is remotely operated by sensing the operator's motion, it can be used only for loading goods, However, there was a problem that it was driven only at a distance where the operator's motion could be detected.

In addition, in the case of the wireless control pesticide sprayer as described above, a nozzle for spraying pesticide is formed on the side of the vehicle body, and a hose reel with a hose wound on the upper part of the vehicle body and a power supply unit are installed, so that only for spraying pesticides. It can be used, but there was a problem that it could not be used for other purposes.

In addition, in the case of the multi-purpose unmanned pest control vehicle as described above, it is possible to simultaneously drive on the running rail and the open field, and can perform chemical spraying and transportation of cultivated crops, but it is difficult to attach and detach the pesticide sprayer, and the rail does not exist. There are many unnecessary configurations when used in places where it is not used, and there are problems in that inconvenience occurs in replacement and repair due to the number of parts and structural weakness due to the adoption of a complex structure.
