Air window

Abstract

The invention discloses an air window. The air window comprises a main frame, a plurality of rotating shafts, a plurality of fan blades, a connecting rod assembly and a driving assembly, wherein the rotating shafts are rotatably mounted on the main frame; the fan blades are connected with the rotating shafts; the rotating shafts correspond to the fan blades one to one; the connecting rod assembly comprises a connecting rod and a plurality of rocker arms; one end of each rocker arm is connected with the corresponding rotating shaft; the other end of each rocker arm is connected with the connecting rod; the connecting rod is used for driving the rocker arms to rotate so as to drive the rotating shafts and the fan blades to rotate; the driving assembly comprises a motor and a worm gear reducer; and the motor is connected with the connecting rod through the worm gear reducer so as to drive the connecting rod to move. According to the air window in an embodiment of the invention, the rotating shafts are connected with one another through the connecting rod assembly, the driving assembly drives the rotating shafts, the fan blades are adjusted synchronously, the speed and the precision of adjustment of air volume of a roadway are greatly improved, the degree of mechanization is high, and the labor and the materials are saved.

Description

technical field [0001] The invention relates to the technical field of mining equipment, in particular to a windshield. Background technique [0002] The air window is the infrastructure for adjusting the air volume of the underground ventilation system of the coal mine. Adjusting the ventilation area of ​​the air window is the most basic means for adjusting the air volume of the underground ventilation system. Reasonable distribution of air flow in each branch is relatively difficult, especially manual operation is difficult to adjust the ventilation area of ​​multiple windshields synchronously, and the adjustment process is time-consuming, laborious, inefficient, and poor in reliability and stability. Contents of the invention [0003] The present invention aims to solve one of the technical problems in the related art at least to a certain extent. [0004] For this reason, the embodiment of the present invention proposes a windshield, which can realize synchronous adju...
