Justification of the combined unit parameters intended for cutting the watering furrows simultaneously with ploghing

The object of investigation: the combined unit consisting of the twolayer plough PYa-3-35 and the device provided for cutting the furrows with spherical disks. The work is aimed at creating the combined unit combining two technological operations providing for the exclusion of using the number of tools when preparing the soil for the moisture-charged irrigation and decreasing the total labour for its realization. Derived and experimentally checked have been the dependencies allowing to determine the setting parameters of the combined unit. The new technical solution has been offered on combining the technological procedures of ploughing and cutting the watering furrows per one pass of the unit. The application of the combined unit for ploughing and cutting the watering furrows allows to exclude the harrow and comb-bed-maker IX-4 utilization and to reduce the labour, money and material and energy expenditures on preparing the fields to the moisture-charged wateringAvailable from VNTIC / VNTIC - Scientific & Technical Information Centre of RussiaSIGLERURussian Federatio
