Calculation and Analysis of the Spray Sowing Chart of Pneumatic Spray Sowing Equipment

A model is established by selecting the particle of the nozzle exit(nozzle) of spray sowing equipment as a research object,the particle trajectory equation obtained with the particle velocity analysis method.At a given condition,a spray sowing chart is drawn,with the overlapping area and missing area in the chart theoretically calculated and analyzed and then the optimal swing frequency of the spray nozzle in the spray operation obtained,which provides a theoretical basis for the improved performance design of sowing equipment.
