The invention relates to a continuous ramming type seismic source device, which is mainly composed of a rack, wheels, a handrail, a heavy hammer, a connecting shaft type bottom plate, a baffle plate, a reset spring, a hinge pin, a T-shaped rod, a semicircular arc clamping groove, crank shafts, a big gear, a small gear, a worm wheel, a worm, a three-phase asynchronous motor and a counter weight, and is characterized in that the middle part of the heavy hammer is provided with a center hole, and the heavy hammer is fixed on the connecting shaft type bottom plate through the baffle plate; the connecting shaft bottom plate is connected with the T-shaped rod through the hinge pin; the T-shaped rod and the semicircular arc clamping groove fixed on the crank shafts form an intermittent motion mechanism; the whole device is fixed on the rack equipped with the handrail and the wheels; and the three-phase asynchronous motor drives the two crank shafts, which are arranged in a left-right symmetric manner and are fixedly connected to the semicircular arc clamping groove, to rotate. The continuous ramming type seismic source device enables the heavy hammer to ram the ground continuously so as to generate continuous controllable pulse signals, and has the advantages of high impact efficiency, adjustable interval, accurate impact force and time-delay-free output signal; and the continuous ramming type seismic source device is small in size, simple in structure, convenient to transport and transfer, and applicable to a complex terrain where field large-scale seismic source equipment cannot operate.
