Modern Designs of Forest Fires Machines for Soil Extinguishment of Fire

Abstract

Theoretical issues of the use of a fire-fighting soilthrower for extinguishing forest fires with the presentation of its practical use in conditions of high fire risk are considered. To assess the effectiveness of the use of new units in the article, a study of the information base for the use of existing technology in modern conditions has been conducted. Promising directions for improving the technology and working bodies of soil throwing machines are described; the advantages and disadvantages of their structures are identified, and ways for further improvement are outlined. In order to eliminate the identified shortcomings, a promising design of a combined machine for extinguishing forest fires with soil, which contains a frame, a linkage mechanism, auger, a ripper, spherical disks, support wheels, skids, and a working body in the form of cutters (front and rear), gearbox, guiding jackets, hydraulic cylinders, transmission, safety devices is presented. A distinctive feature of the developed design of the fire-fighting soil-thrower is to increase the efficiency of the operation of the dirt throwing machine and fire-break maker by removing the upper fire-hazardous cover consisting of plant residues. This is achieved due to the fact that a device in the form of a double-sided auger installed in front of the discs is inserted into the design of the primer-stripper. The auger shifts the ground cover from the center to the left and right sides, forming an open mineralized strip.

Mathematical Model of Forest Fire Soil-thrower Movement

“…Modern technical means used for carrying out preventive and forest fire activities have various drawbacks: they create narrow mineralized strip, do not form ground ripraps of necessary volumes, have low productivity, have insufficient constructive reliability of milling tools, which restrains their use on heavy forest soils [14,15].…”
