The invention provides a spray rod damping device, which is used for suppressing vibration of a spray rod (4) of a spray rod type spraying device. The spray rod type spraying device comprises a link arm (2) mounted on a vehicle body (1); a lifting cylinder (3) arranged between the vehicle body and the link arm and used for lifting the link arm; a working oil supply and discharge device (5) used for supplying a working oil to the lifting cylinder for supporting the link arm or discharging the working oil from the lifting cylinder, thereby making the lifting cylinder telescope; and a spray rod (4) used for spraying a control solution, wherein one end of the spray rod is supported on the link arm and the other end is set as a free end. The spray rod damping device is provided with a pressure accumulator (60) and a damping valve (61), wherein, the pressure accumulator is connected to an oil chamber (62) of the hydraulic cylinder and a spring chamber (63) for applying the pressure to the oil chamber, and the damping valve applies the resistance to the working oil between the hydraulic cylinder and the oil chamber. |
