Study on Prevention of Soil Adhesion to Rotary Cover by Vibration (Part 2)

Effects of Spraying Angle and Soil Moisture Content on Soil Adhesion

Abstract

The purpose of this study is to find out an effective method for preventing soil sticking to rotary cover by vibration. A laboratory experimental apparatus was constructed using a steel plate as a model. Five grades of moisture content for silt loam soil were considered in the experiments. Test soil was sprayed to the steel plate under two kinds of conditions, with and without vibration, at several spraying angles. Soil spraying velocities were varied by changing the pressure of air compressed. When the plate was not vibrated, the soil sprayed with smaller spraying angles did not stick to the plate. When the plate was vibrated, a remarkable effect was shown in preventing with large vibrational acceleration of the plate.
