The article deals with the problem of creating machines and units for the prevention and suppression of forest ground fire. The purpose of the study is to increase the efficiency of the working process of the soil-throwing machine by substantiating the parameters of the energy-saving hydraulic drive of the rotor-thrower. The rational values of the pre-charging pressure and the working volume of the pneumohydraulic accumulator have been established, which ensure the reduction to a minimum of the number of operation of the safety valves when the rotor-thrower meets obstacles. The optimum charging pressure of the pneumohydraulic accumulator is 6 … 7 MPa, the working volume is 5 … 8 dm 3 , while the energy-saving hydraulic drive stores energy of about 15 … 17 kJ during the working cycle, pressure surges do not exceed 13.3 MPa, and the recovered energy at density of obstacles up to 200 pcs / km due to the reduction in the number of operation of safety valves can be about 3000 kJ per 1 km of strip laying. The productivity of the forest fire ground-throwing machine with a new energy- saving hydraulic drive increases by 16-22% while reducing energy consumption by 7-8%.
