Forest fire-fighting soil-thrower: improving the efficiency of the work processes

Abstract

Abstract The analysis of the work processes of technical equipment used for forest fire control and preventive activities has revealed that they do not meet the requirements of the process flows. The aim of the work was to increase the efficiency of the work processes of new forest fire-fighting soil-thrower by optimizing the parameters of the milling thrower. The optimization task has been to search for the values of the length and width of the milling thrower blades. These values should provide the highest productivity and smallest supplied power with the average range of soil displacement. Based on the optimization results, the optimal blade length of the milling thrower was revealed in the range of 200-230 mm, and the width of the blade was 150-220 mm. With optimal parameters of the working body, a fire-fighting machine throws soil into the fire zone at a distance of up to 21 m. It consumes no more than 38 kW of power, and its productivity is 0.22 m3/s on the average.
