ANALYSIS OF RESEARCH OF WORKING PROCESSES OF AUGER WORKING BODIES OF TECHNOLOGICAL MACHINES
At modern manufacturing enterprises of the construction industry, mechanical engineering, food, agricultural, forestry and other industries, the transportation of dusty, fire hazardous and small-sized materials is carried out mainly by screw conveyors (augers). In addition to screw conveyors, feeders with an active working body of the screw type, used in active units of technological units, as well as in the form of separate machines, have gained widespread use. The main purpose of feeders at manufacturing enterprises is the uninterrupted and uniform supply of materials to crushing, grinding, molding and other technological machines or to transport devices. Combine harvesters use universal auger cutting devices. In forestry, soil-cultivating auger cutters, auger de-wingers of forest seeds, additional auger working bodies of forest fire ground guns are used to remove soil cover and combustible materials. An analysis of patent materials on the creation of structures for forest fire ground-throwing machines with auger working bodies shows that they do not provide for safety devices to reduce the dynamic loads on the working bodies of the augers of forest fire ground-throwing machines and protect them from breakage when hitting stumps and large roots. Therefore, the aim of the authors' research is to increase the efficiency of preventing and extinguishing forest fires by substantiating the design and technological scheme of the ground-throwing machine and rational parameters of the hydraulically driven screw, which ensures the removal of the ground cover with combustible materials and reducing the dynamic loads of the working process.
