Method for improving blocking of grate bars of sintering machine

The invention belongs to the technical field of steel production equipment, and particularly relates to a method for improving sintering machine grate blockage, which comprises the following steps of: adding grate rapping at a descending part of a sintering machine, adding a counterweight at one end of a seesaw, forming a hammer head at the other end of the seesaw and forming a group by a plurality of columns by utilizing a lever gravity principle, and adjusting to a proper height; the shaft with the arc-shaped fin plate is driven by the motor to rotate and naturally falls after reaching the highest position, and the hammer at the other end is driven to impact the grid section, so that blockages in gaps of the grid section are vibrated to fall off. Compared with existing equipment, gaps among the grate bars are prevented from being blocked, the utilization rate of effective air volume is guaranteed, and stable productivity of the sintering machine is guaranteed; a post worker does not need to frequently check
