FORCED OSCILLATIONS AS A METHOD TO IMPROVE SERVICE FACTOR OF TILLAGE MACHINES
Soil tillage remains the most important and power consuming operation in plant growing. Need for higher plant production products output to cover increased demand for domestic foodstuff results in usage of highly-productive wide-coverage machinery based on heavy power-supplied tractors. Operation of heavy machinery increases soil density thus reduces its fertility. The proposed tillage machine with mechanical direct effect vibrators enable to reduce the share of power-supplied tractors when tillage technological operation is being done. Changing operation modes of direct effect vibrators is made depending on operation conditions by oscillation rate of eccentric rate and slope angle of an eccentric vibrator. Operation correction of dead-weight vibrator mounted on main power networks is done automatically.
