Description

[0001] The present invention relates to a portable spraying apparatus with tractor,

The present invention relates to a portable sprayer capable of being used as a tractor, and more particularly to a portable sprayer capable of serving as a tractor, and more particularly to a portable sprayer having a spray container for containing a spray solution therein and a control device for controlling the pump motor to spray the spray solution The present invention relates to a portable atomizer which can be used as an external battery and an external water supply, is excellent in portability and expandability, is easy to adjust the spray interval, and can be used with a tractor.

Generally, the pesticide sprayer is a device used for spraying biochemical pesticides for controlling pests and weeds caused during cultivation of crops.

These pesticide sprayers are mainly used for attaching to various agricultural machines or installing a portable pesticide sprayer for installing wheels separately, and a portable agricultural chemical sprayer for installing a suspenders so that a user can spray the sprayer on the shoulder and perform a spraying operation. The portable agricultural chemical sprayer is driven by a manual chemical agitator sprayer which pressurizes and injects the liquid agent by gravity and a pump which is connected to an engine or a motor for burning the fuel

There is an automatic pesticide sprayer to spray. The liquid agent is a diluted mixture of pesticide and water, and the concentration is adjusted according to the purpose of use or the type of pesticide.

The manual pesticide sprayer is cheap, but it injects the liquid agent by the manpower, so the user feels fatigue easily, and the user is burdened in consideration of the aging of the rural area.

Therefore, in recent years, there has been a demand for a liquid agent passage through which a suspenders can be carried, a motor connected to an engine or a battery installed in a lower part of the liquid container and operated by burning fuel, and a pump connected to the engine or motor, Automatic pesticide sprayers are widely used.

On the other hand, in general, the battery sprayer requires a time to fully charge the battery, and when the battery capacity is low, continuous spraying time is very short, and the battery is often not used properly.

In case of special tractor, spraying device can be installed in the loading box and sprayed while performing rotary work. There is a risk of safety accident of workers due to a large size of spraying device and a separate operation method.

Especially, when rotary work is performed with a dedicated tractor, it is difficult to control spraying direction or spraying speed when spraying the herbicide at the rear, and there is a problem that it is difficult to finely spray the edge of agricultural land or the invisible part.

In addition, even when the portable sprayer is sprayed by approaching the agricultural land through the agricultural land, there is a problem that the spraying time is very short depending on the battery capacity and the spraying method is difficult to control.

In addition, when pesticides or nutrients are sprayed on specific plants, it is necessary to continue spraying at a constant rate. However, it is necessary to control the spray interval according to the crop or pesticide component, but conventional sprayers have no such convenient function.

In addition, the conventional battery reel sprayer has only basic functions such as checking the remaining capacity of the battery and notifying the discharge of the battery, which is inconvenient to use.
