Temperature control louver type air capacity control mechanism of cooling system of bulldozer

The utility model provides a temperature control louver type air capacity control mechanism of a cooling system of a bulldozer. The temperature control louver type air capacity control mechanism of the cooling system of the bulldozer structurally comprises blades, a supporting rod, an adjustment rod, a slider, a stopper mechanism, a worm wheel and a worm. The stopper mechanism comprises an upper stopper point and a lower stopper point. The blades are hingedly mounted on the supporting rod and the adjustment rod. The worm wheel is engaged with the worm. The worm wheel rotates to drive the worm to move vertically to further drive the adjustment rod to move vertically. The supporting rod is connected with the slider which is mounted on guide rails. The supporting rod can only move horizontally under the action of the slider and the guide rails so as to achieve the change of the horizontal distance between the supporting rod and the adjustment rod.
