[0002] In agricultural production, crop spraying is a crucial step in ensuring healthy crop growth and controlling pests and diseases. However, traditional crop spraying devices have significant shortcomings. Uneven spraying is common, resulting in pesticides not being evenly distributed across the crop and affecting the control effect. Furthermore, the spray has poor penetration, making it difficult to reach deep into the crop clump, leaving the lower and denser parts of the plant without effective application, increasing the risk of pest and disease recurrence, and also causing pesticide waste and environmental pollution. Therefore, a crop spraying device with adjustable double-row angle is proposed. Summary of the Invention
