Description

Pesticide spreading device using model helicopter {CROP-DUSTING DEVICE THAT USE MODEL HELICOPTER}

The present invention relates to a pesticide spraying device, and more particularly to a pesticide spraying device using a model helicopter.

Pesticide spraying is recognized as a necessity in most of the cropland, except for those that grow organic crops.

Most of the very small arable lands are sprayed using sprayers for spraying pesticides. In this case, farmers carry sprayer tanks directly with the sprayer tank on their back and hold the nozzle with one hand, and spray the sprayed pesticides on the skin. They may reach or enter the body through the respiratory system.

As such, the spraying of pesticides by hand has to take up the nebulizer tank and move the arable land so that the physical consumption is severe and the risks such as neuropathy caused by pesticides are taken.

In order to solve this problem, in recent years, most farms use a vehicle equipped with a power sprayer or a cultivator, and in some farms, a model helicopter is used to spray pesticides in the air.

Conventionally, in some farmhouses, pesticide spraying using a model helicopter uses a model helicopter using gasoline or methyl alcohol as a raw material, and a model helicopter with a pesticide container filled with pesticides is equipped with a pesticide box and an injection device. Was sprayed over the pesticides.

However, conventionally, in order to mount a pesticide box and a spray device in a model helicopter, the model helicopter needs to use a model helicopter that can weigh more than 30 kg (about 30 liters of pesticide) to bear the weight of the pesticide box and the spray device. There was no choice but to use a helicopter, and when using a real model helicopter, there was a limit to attach a pesticide box about 30 kg (about 30 liters of pesticide) due to the characteristics of the model helicopter.

On the other hand, when spraying pesticides on rice fields, about 500 liters of pesticides are used on arable land of about 1000 pyeong, and pesticides are sprayed with pesticides by model helicopters. After returning the model helicopter to the ground, the pesticides had to be stored again in the pesticide container and then sprayed over the model helicopter again. As a result, it has been cumbersome to repeatedly fill the pesticides, and the model helicopter has to be repeatedly returned from above to the ground in order to fill the pesticides, which increases fuel consumption of the model helicopter and takes more time to spray the pesticides. There was a problem.

Therefore, the conventional pesticide spraying work using a model helicopter was expensive to prepare equipment, there was a problem that the consumption of fuel and labor time for operating the model helicopter is increased.

Therefore, the problem to be solved by the present invention is to reduce the initial cost for equipment installation, to continuously spray pesticide for a long time after the start of the operation of the model helicopter, to minimize the maintenance cost, to improve the spraying power of the pesticide To provide a pesticide spraying device using a model helicopter.
