Аннотация

In this article. In the case of cleaning and drilling the bottom of the screwdriver with air, due to the low thermal conductivity of the air, problems arise with reducing the efficiency of the rock-shattering tool as a result of the formation of high temperatures on the bottom of the screwdriver, which negatively affects the efficiency of the rock-shattering tool. In the process of air-assisted drilling of the skewers, an improved design of a hollow tube drilling projectile was developed to air-clean and drill the bottom of the skewers in order to cool the temperature of the air being sent to the skewers.
