Abstract

The invention relates to a poking wheel type air quantity adjustable air window which has a simple structure and is convenient to use. The air window comprises a barrel, wherein a dial is fixedly connected outside the barrel and is provided with scales; a fixing sheet is fixedly connected in the barrel; an adjusting sheet and a transmission rod are arranged on the fixing sheet in a relatively rotating mode; one end of the transmission rod is fixedly connected with a poking wheel, and the other end of the transmission rod is fixedly connected with a worm; the poking wheel is positioned outside the barrel; the adjusting sheet is fixedly provided with a worm wheel; the worm wheel is meshed with the worm; the shape of the fixing sheet is the same as that of the adjusting sheet; the fixing sheet has a fan blade shape; and indicating arrows are arranged on the adjusting sheet and correspond to the scales on the dial. The air window is used in the technical field of mine ventilation, can conveniently and quickly adjust the air quantity of ventilation structures such as an air retaining wall, an air door and the like, more reasonably distributes air, improves ventilation quality and the labor condition of staff, has a simple structure and is convenient to use.

Description

technical field [0001] The invention relates to a mining device, in particular to a dial-type windshield with adjustable air volume. Background technique [0002] At present, the types of windshields used underground mainly include digital scale windshields, adjustable louver windshields, impeller-type windshields with precise scale adjustment, and button-type windshields with precise scale adjustment. The air sash used often needs to be adjusted according to the needs of production. Each time the air volume is adjusted, it must be repeatedly measured and adjusted many times to meet the requirements. The difficulty may also lead to unreasonable air volume distribution. Contents of the invention [0003] The object of the present invention is to provide a dial wheel type windshield with adjustable air volume which is simple in structure and easy to use. [0004] To achieve the above object, the technical solution adopted in the present invention is: [0005] A dial-type ...
