Forest fires are studied and developed in all countries with forest resources. However, despite large number of studies, the problem is still far from being resolved and fires still cause great damage to forests. The article deals with research on the influence of the screw drum parameters on the quality of removing the surface soil layer from combustible materials and on the performance of the forest fires soil-sweeping machine. The geometric parameters of the screw drum of the forest fires soil-sweeping machine were optimized. As a result of optimization, the optimal values of the screw channel depth in the range of 7.5-8.7 cm and the screw pitch of 23-40 cm were obtained. At these optimal values, the ground cover content in the thrown soil stream will be less than 15 %, the productivity of the forest fires soil-sweeping machine will be more than 40 kg/s, and the power consumption will be less than 12 kW.

所有拥有森林资源的国家都在研究和发展森林火灾。然而，尽管进行了大量研究，但问题仍远未解决，火灾仍对森林造成巨大破坏。研究了螺旋滚筒参数对可燃材料去除表层土层质量和林火清扫机性能的影响。对林火扫地机螺旋滚筒的几何参数进行了优化。经过优化，得到了螺槽深度在7.5~8.7 cm范围内、螺距在23~40 cm范围内的最优值。在这些最佳值下，抛出的土壤流中的地被植物含量将小于 15%，
