ABSTRACT

The main requirements for carrying out preventive and forest fire works are revealed. It is established that the main drawback of the used soil-sweeping machines is the small amount of soil supplied, its distribution over a large area by a small layer. This is ineffective when extinguishing a fire. Also a disadvantage is the low performance due to the low speed of the machine (up to 2 km / h). The main ways to improve the efficiency of working processes of forest fire engines and tools are considered. The working processes of new designs of soil-sweeping machines with preliminary preparation of the soil shaft before the thrower cutters are considered. Milling of the fed soil is excluded from the working process of the blade of the thrower cutter. This function is performed by spherical disks mounted on the front. In addition, the disks form a soil shaft for subsequent throwing by the rotor. But this innovation did not improve performance. Fire extinguishing is ineffective due to the strong dispersion of the soil in a thin layer, as well as the loss of volume of the ejected soil when dust is formed. The proposed method of extinguishing a low-level fire involves the formation of a shaft of loosened soil above the ground and throwing it into the fire zone. In the process, a layer of soil is cut off, then raised and divided into separate layers. At the same time, moving soil layers have different trajectories and different speeds when entering the zone of fire movement. At the same time, it is covered with a certain layer of soil, which is necessary for extinguishing a ground forest fire at a high speed.(patent no. 2706040).

ВВЕДЕНИЕ

В настоящее время актуальной проблемой в лесном хозяйстве является эффективное проведение профилактических и лесопожарных работ, поскольку пожары представляют серьезную опасность для окружающей среды, населения и экономики. Для таких работ применяются лесные плуги, ПКЛ-70, ПЛ-1, ПКЛН-500А, а также фрезерные грунтометы – прокладыватели ПФ-1 и АЛФ-10, ГТ-3, разработанные в ЛеНИИЛХе. Основными недостатками ПФ-1 и ГТ-3 является то, что оба этих орудия могут эффективно работать только на песчаных и супесчаных почвах [1, 3]. Грунтомет ГТ-3 подает малый объем грунта на кромку огня, распределяет его тонким слоем на большой площади и этого недостаточно для тушения огня. а также малопроизводителен из-за низкой скорости движения агрегата (до 2 км/ч) и из-за того, что лопатка фрезы-метателя работает только своей кромкой, не захватывая максимально возможный объем выбрасываемого грунта.
