Description

Portable Pesticide Spraying Apparatus Having Convenient Moving Structure}

The present invention relates to a mobile pesticide spraying device, and more particularly, to a mobile pesticide spraying device including a structure capable of easily and safely moving a liquid pesticide and carrying out a pesticide spraying operation after storing the liquid pesticide It is about.

In general, a spray device refers to equipment for spraying a specific type of liquid, such as fire extinguishing liquid, pesticide, etc., that meets the purpose of use to a predetermined distance.

These spraying devices are used in various forms in various fields. In the case of spraying equipment for spraying pesticides, a worker must carry a pesticide container containing pesticides on his back while manually pumping a rotary lever to spray pesticides.

Spraying equipment for spraying pesticides according to the prior art mentioned above was forced to make the worker easily tired and hard work while spraying pesticides for a long time because the operator had to move the lever one by one to perform the pumping operation. In particular, considering the aging trend of rural areas today, it is urgent to develop a spraying equipment for spraying pesticides with good performance for spraying pesticides.

For this purpose, when spraying using a spray pump, the motor for driving the spray pump is restricted to use only a DC motor due to operation in farmland, so there is a limitation in spraying pesticides over a wide area.

In addition, in the case of spraying with a long spray hose for spraying a wide area, the work of winding the spray hose or unwinding it for use further increases the fatigue of the operator.

Accordingly, in order to solve the above problem, a bobbin on which a spray hose is wound is provided, and a spray device in which a drive shaft accommodating a drive motor and the bobbin are connected to enable power transmission, and a spray device coupled to enable power transmission selectively through a clutch is used. It became.

That is, during spraying, only the drive shaft and the spray pump are connected so that power transmission is possible through the clutch interruption, and the clutch is interrupted so that power transmission is possible between the drive shaft and the bobbin to wind the spray hose at the end of the spray operation.

However, due to the interposition of such a clutch, a problem arises in that the configuration is complicated, the scale of the device is enlarged, and overall costs for realizing the configuration are increased.

In addition, the device is enlarged and the center of gravity of the entire device is eccentric, causing severe vibration or shaking when operating the device.

In order to solve this problem, as shown in FIG. 1, a spraying device for spraying agricultural chemicals in which a bobbin 4 for winding a pumping means 30 and a spray hose 42 is mounted on a housing 10 having a box structure has been developed. It became.

In the case of a spraying device for spraying pesticides according to the prior art, the location must be changed from time to time using a moving means such as a manager, a tractor, etc., and there is a problem in that a tank in which pesticides are stored must be separately provided for spraying.

Therefore, there is a need for a technique capable of solving the above-mentioned problems according to the prior art.
