The invention provides a biaxial
inertia excitation tamping pick, and relates to railway maintenance equipment, in particular to the biaxial
inertia excitation tamping pick with the advantages that directional vibration force is provided, and the vibration effect is good. The biaxial
inertia excitation tamping pick uses a
gasoline engine or a
diesel engine as prime power. The biaxial inertia excitation tamping pick is characterized in that the tamping pick comprises a tamping
handle, a tamping case, a vibration reduction tube, a transmission device and an excitation vibration component, wherein the vibration reduction tube is fixed on the top of the tamping case; the tamping
handle is arranged on the vibration reduction tube; the excitation vibration component is arranged inside the tamping case, and is connected with the prime power through the transmission device. Through two
parallel excitation vibration shafts and two groups of eccentric blocks in opposite arrangement on the excitation vibration shafts, the two groups of eccentric blocks enable vibration excitation forces at the left side and the right side of the tamping pick to mutually counteract and to be converted into vibration excitation force in a front and back direction; the tamping efficiency is improved; meanwhile, a flow guide plate is added; the flow guide plate is used for decomposing the front and back force into forward force and downward force, so that a pick head can automatically move forwards; front
ballast is pushed and naturally flows to the bottom of a sleeper; the special requirements of railway construction are met.
