This utility model discloses a cleaning component for a boiler auxiliary slag discharge device, including a slag discharge frame and side plates. The bottom of the side plates is fixedly connected to both sides of the top of the slag discharge frame. An electric telescopic rod is fixedly connected to the rear side of the outer side of the side plates, and a transmission plate is fixedly connected to the output end of the electric telescopic rod. This utility model, by setting a cleaning groove and activating the electric telescopic rod, can perform cleaning during the slag discharge process. This allows slag entering the slag discharge frame during cleaning to be temporarily blocked at the front of the top of the slag discharge frame, avoiding the reduction in slag discharge efficiency caused by cleaning when slag discharge is stopped. It also solves the problem that the cleaning device can only be activated when the user stops using the slag discharge device, otherwise, after the cleaning device moves to clean, slag will be discharged again in the opposite direction, causing slag to backfill when the cleaning device resets, resulting in a reduction in slag discharge efficiency. This achieves the effect of avoiding slag backfilling.
