An analysis of the conducted studies of the causes of occurrence, methods and techniques used to combat and prevent a forest fire, including forest plows, ditchers and soil throwers, is presented. It has been established that units with active working bodies are the most effective, but the existing milling working bodies do not allow delivering the required amount of soil to the edge of a forest ground fire. The aim of the study is to increase the efficiency of the working process of a forest fire soil thrower by substantiating the parameters of a three-stage rotor-thrower with a hydraulic drive. A mathematical model of the working process of a three-stage rotor-thrower and a software package were compiled, with the help of which the main design and technological parameters of the soil-throwing unit were determined. Laboratory tests were carried out using the method of a full-factorial experiment. The optimal value of the angle of installation of the blades on the rotor-thrower in terms of the volume of thrown soil of 0.1 m3 per one m2 of the area of the mineralized strip is the angle of -10º, however, in terms of energy consumption, the optimal angle of inclination of the blades for all modifications of the rotor is an angle equal to 00. As a result of a comparative analysis by the method of alternatives it was found that the optimal modification of the rotor-thrower is R-20 at a rotation frequency of 20 rpm. |
