The utility model discloses a bagasse boiler feeding machine, including the casing, the inside of casing is provided with the pivot subassembly, and the upper portion of casing has a feed inlet, and the lower part has a discharge gate, the pivot subassembly rotate with the slag charge by feed inlet propelling movement to discharge gate, wherein, the casing has first casing module and second casingmodule, first casing module swing joint extremely second casing module forms with the combination the casing. The utility model discloses with two module elastic movable connection of casing, when the material sediment fell into the clearance of pivot subassembly and casing inboard, the material sediment increased the clearance, and discharges from the discharge gate, avoids expecting the sediment to pile up gradually in the clearance, got more and more, and blocked the pivot subassembly of dying, had solved the current bagasse boiler feeding machine ubiquitous material sediment card problemof dying.
