Abstract

The utility model discloses an efficient submerged chain conveyor driving mechanism which comprises a submerged chain conveyor body, and a first buffering seat plate and a second buffering seat plate are welded to the two sides of the submerged chain conveyor body respectively. Due to the fact that the dragging chain wheel and the like are installed, when the device is used, after the submerged chain conveyor main body is changed into dual drive formed by the first drive motor and the second drive motor, the dragging component on the submerged chain conveyor main body is stressed more evenly, and when the dual-drive structure drives the submerged chain conveyor main body to operate, the dragging component is not damaged. The two dragging chain wheels on the first dragging assembly and the second dragging assembly have no master-slave difference, so that the situation that gear teeth of the dragging chain wheels are abraded inconsistently is avoided, and the dragging mechanism formed by the first dragging assembly and the second dragging assembly is stressed uniformly; the dragging chains on the two sides formed by the first dragging assembly and the second dragging assembly are even in stress and consistent in abrasion, and therefore the situation that the chain structures on the two sides are different in length is avoided.
