BACKGROUND ART [0002] The present disclosure relates to a pesticide spraying apparatus, and relates to a pesticide spraying apparatus that can travel on a crop to move pesticides and the like on a crop while moving along the furrow.

Generally, crops refer to edible crops, artificial crops, forage crops, fertilizer crops, and horticultural crops grown in rice fields or fields.

Cultivation of crops can be done directly in paddy fields or in fields, or in greenhouses, etc., and after laying the land on which the crops are to be cultivated, the field is made to grow.

At this time, a relative depressed form of trough is formed between the large troughs and the troughs, and the worker sows seeds while moving along the troughs, plants or seeds the seedlings, gives a smile, and harvests when the crops grow.

While the above-mentioned troughs are narrow in width, the crops are sprayed with pesticides to protect crops from various insect pests and to increase yields.

At this time, in the case of a small-sized crop growing plant, the operator puts the manual sprayer on the shoulder and moves the paddy between the narrowed gullet, spraying the pesticide directly on the crop.

On the other hand, in the case of a large-scale crop growing complex, the pesticide spraying device is mounted on a vehicle or a tiller, and the pesticide is sprayed on the crop using a hose-type pesticide sprayer connected to the pesticide spraying device.

As described above, even when a vehicle or tiller is used for spraying pesticides on a crop, the vehicle and cultivator can not directly enter the trough with a narrow groove, resulting in a problem that the efficiency of spraying the pesticide drops.
