[0001] The invention relates to the field of spraying pesticides, and in particular to a traveling pesticide spraying device with an adjustable spraying range for applying pesticides. Background Art

[0002] A pesticide sprayer is a type of agricultural pesticide application machinery that mixes water with liquid pesticide and then sprays the liquid onto the surface of an object under pressure. It is also a type of agricultural plant protection machinery.
