Mine ventilation device for mine safety production

Abstract

This application belongs to the field of mining equipment technology, specifically relating to a mine ventilation device for safe production in mines; it includes an installation barrel with an air outlet side, and assembly barrels are spaced apart on the air outlet side of the installation barrel. A sealing plate is installed at the air outlet of each assembly barrel, used to open or close the air outlet of the assembly barrel. Several openings are provided on the side of the installation barrel facing the assembly barrels; several air supply pipes are rotatably disposed between the installation barrel and the assembly barrels, each air supply pipe connecting an opening to an assembly barrel, and each air supply pipe has an exhaust port circumferentially provided; a transmission mechanism is installed in the installation barrel and used to drive the air supply pipes to rotate; and a blower mechanism is installed inside the installation barrel to blow air towards the air outlet side of the installation barrels. This application has a simple and reasonable structure, and during use, it has two modes: multi-angle uniform air supply and centralized air supply, which can be flexibly switched according to actual needs, making it highly applicable and providing uniform air supply.
