PURPOSE: A device for cleaning a connecting pipe of a wood pellet boiler is provided for the stable heat exchange and constant flow velocity of the combusting gas inside the connecting pipe by preventing debris blockage on the heating surface. CONSTITUTION: A device for cleaning a connecting pipe of a wood pellet boiler (1) comprises a cleaning bar (110), a connecting bar (120), an operating bar (130), a cam bearing (140), and a driving motor (150). The connecting bar connects the upper end of the cleaning bar to be adjacent and is extended to vertically move by penetrating through an upper part of a stovepipe. The operating bar connects the upper end of each connecting bar and is installed to interlock. The shaft-fixed cam bearing is eccentric for the latching on one end of the operating bar in a specific section when engaging. The driving motor drives the cam bearing and adds the impact by free fall of the cleaning bar lifted vertically by the operating bar. |
