Abstract

The invention discloses a coal mine fully-mechanized excavating working face air flow field mechanical control device which comprises a straight line rail, an air flow field adjusting air cylinder, asupporting frame, a straight line displacement mechanism and a mounting rod. The straight line displacement mechanism is arranged between the supporting frame and the straight line rail, the air flowfield adjusting air cylinder comprises an air cylinder air outlet, an air cylinder frame and a negative pressure air cylinder, the upper end of the mounting rod is fixedly connected with the lower endof the air cylinder frame, the air cylinder air outlet comprises a blade connecting ring, an outer blade and inner blade, an outer blade drawing line adjusting mechanism is arranged between the air cylinder frame and the mounting rod, a straight line displacement brake mechanism is arranged between the supporting frame and the mounting rod, a rotatable adjusting mechanism is arranged between thesupporting frame and the air cylinder frame, a rotating brake mechanism is arranged on the mounting rod, and a pitching adjusting mechanism is arranged on the rotating brake mechanism. The device is convenient to mount and use, high in reliability, full air field air flow characteristics and gas and coal dust migration rules can be changed, working efficiency is improved, safety of coal mine fully-mechanized excavating surface is ensured, energy is saved, and green ventilation is achieved.

Description

technical field [0001] The invention relates to a control device for an air outlet, in particular to a mechanical control device for an air flow field in a coal mine fully mechanized excavation face. Background technique [0002] According to statistics in recent years, the gas and coal dust explosion accidents that occurred during the tunneling process accounted for 60% to 70% of the total number of mine gas and coal dust explosion accidents. With the extension of the depth and breadth of coal mine mining, a series of problems such as long ventilation distance, insufficient air volume at underground excavation sites, excessive ventilation resistance of tunnel tunnels, and reduced ventilation efficiency have gradually appeared in the mine excavation working face. The tunneling coal roadway is a single-headed roadway, and the ventilation circuit is incomplete. To dilute and remove the gas gushed out from the coal body and the dust generated during operation is to press into t...
