AI Technical Summary
Existing chemical weed control devices for corn seedlings cannot effectively guarantee reasonable coverage of the target area between rows and reduce pesticide drift when faced with different corn planting row spacing, resulting in pesticide damage and waste.
An adjustable windbreak is used, and the opening angle of the windbreak is adjusted by a telescopic electric push rod and a traction rod system to ensure that the spraying range of the fan-shaped nozzles covers the gaps between corn rows and reduces pesticide drift.
This method achieves reasonable coverage of the target area between rows under different corn planting row spacings, reduces pesticide drift and phytotoxicity, improves the coverage efficiency of pesticide application, and reduces pesticide waste.
