The invention relates to the technical field of biomass particle production equipment, and discloses a feeding device capable of adapting to different docking devices for biomass particle producing. The feeding device comprises a conveyor belt, supporting frames are arranged at the bottom of the conveyor belt symmetrically, and a supporting rod is arranged at the top of the supporting frames in apenetrating mode. By arranging the conveyor belt, the supporting frames, the supporting rod, a first connecting plate, a handle, a limiting plate, a positioning rod, a hollow block, a second connecting plate, a first bolt, a first twisting block, a clamping rod, a first fixing block, a fixing plate, a positioning post, a baffle, a second bolt, a placing box, a supporting plate, a tooth plate, a motor, a gear, a positioning block, a second fixing block, a strut, a third fixing block and a mounting block for matching use, the problem that an existing feeding device cannot be lifted and lowered is solved, and the feeding device capable of adapting to the different docking devices for biomass particle producing has the advantages of being able to be lifted and lowered, the economic expenditureof a user is reduced, the practicability of the feeding device is improved, and the feeding device is convenient for a user to use.
