AI Technical Summary
The existing small sprayers have non-adjustable wheel track and fixed spraying angle, which makes it easy to crush crops and spray pesticides unevenly in small-scale experimental fields, affecting the reliability of experimental results and pesticide utilization.
A special sprayer for experimental fields in a small area was designed. Through adjustable rubber tire wheel track, universal joint and telescopic spray pipe, combined with plow shovel and limiting structure, the wheel track and spraying angle can be flexibly adjusted. It also integrates ditching function to ensure uniform coverage of pesticide liquid.
It avoids crop trampling, improves the accuracy of test data and pesticide utilization, reduces labor and time costs, and enhances the uniformity of spraying and the control effect.
