Power indicators of grind gun operation depending on the depth of soil treatment

The article discusses the design of the working body of a forest fire soil thrower, designed to fight forest ground fires by laying a mineralized strip with simultaneous throwing of the edge of the fire with mineralized soil, with the determination of its power indicators depending on the depth of the strip.

For the design of the working body of the forest fire ground thrower, a utility model patent of the Russian Federation No. 117091 was received, the patent holder of which is the Siberian State Technological University.

The utility model relates to devices designed for laying protective mineralized strips, as well as extinguishing ground fires with soil, especially in waterless forests. The utility model allows to increase the width of the mineralized strip due to the implementation of the working body in the form of throwing knives, made in the form of a "rod" spiral section, installed on the carrier disk at an angle α between the rear edge of the knife and the plane of rotation of the milling disk, and rotated relative to the trailing edge in the direction movement through the angle β. In this case, the diameter of the carrier disk is equal to the diameter of the circle described by the ends of the throwing knives, which increases the ground support area enclosed between the front surface of the carrier disk and the throwing knives.

Throwing knives separate the chips from the soil mass, while the cut volume of soil rests against the walls formed by the interface of the frontal plane of the carrier disk and the throwing knives. Throwing occurs as a result of imparting kinetic energy to the cut off part of the soil from throwing knives and the frontal plane of the carrier disk.

The scheme and princip endences of the required power on the depth of the strip being laid are obtained.le of operation of the working body of the forest fire ground thrower are considered, the dep

The introduction and use of ground throwers in the fight against forest fires will minimize damage and harm to the forest ecosystem.
