Biomass gas cross-shaped air distribution combustion device

The biomass gas cross-shaped air distribution combustion device comprises a pipe head, electric push rods, push blocks and air distribution plates, the electric push rods are fixedly connected to the upper side and the lower side of the pipe head, the push blocks are fixedly connected to the front ends of the electric push rods, the air distribution plates are arranged at the front ends of the push blocks, communicating grooves are formed in the surfaces of the air distribution plates, and the communicating grooves are communicated with the pipe head. A metal damping sliding block is attached to the interior of the communicating groove, a sliding groove is formed in the side face of the pipe head, an extending groove is formed in the front end of the pipe head, the electric push rod and the push block are symmetrically distributed on the upper side and the lower side of the pipe head, the outer surface of the pipe head is flush with the outer surface of the push block, and a through hole is formed in the surf
