Current collector capable of adjusting gas flow rate

The utility model discloses a current collector capable of adjusting gas flow velocity, which comprises a flow guide frame and a flow limiting plate, the right side of the flow guide frame is connected with a pipe body, the outer side of the flow guide frame is provided with adjusting handles, the inner sides of the adjusting handles are connected with connecting rods, the bottoms of the connecting rods are connected with blades, the inner cavity of the pipe body is provided with a ventilation cavity, and the ventilation cavity is provided with a ventilation hole. Flow limiting blocks are installed at the two ends of the inner side of the pipe body. According to the flow collector capable of adjusting the gas flow speed, effective flow dividing treatment can be conducted when airflow is guided, meanwhile, the gas flow speed can be effectively adjusted, the situation that the loss rate is too large due to the fact that the gas flow speed is too high is prevented, the circulating airflow can be divided through
