The invention discloses an electro-hydraulic vibration exciter of concrete pavement rubblizing equipment. The electro-hydraulic vibration exciter comprises an hydraulic cylinder, a piston rod, a rotary valve, a hydraulic pump, an oil tank and an overflow valve, wherein a piston is arranged on the piston rod of the hydraulic cylinder, is glidingly arranged in a piston cavity in the hydraulic cylinder and divides the piston cavity into a first piston cavity and a second piston cavity; a gravel hammer is arranged at the driving end of the piston rod; a direction control opening A of the rotary valve is connected with the first piston cavity through supply liquid; the output end of the hydraulic pump is connected with a pressure oil opening P of the rotary valve through supply liquid by a pressure oil passage; an oil return opening T of the rotary valve is connected with the oil tank by return liquid; the pressure oil passage is connected with the second piston cavity through by-pass supply liquid; and a by-pass point of the pressure oil passage is also connected with the overflow valve through supply liquid. When the rotary valve works, the pressure oil opening P and the oil return opening T are alternatively conducted with the direction control opening A, so that the hydraulic cylinder piston is driven to reciprocate in the oil tank. The electro-hydraulic vibration exciter has the advantages that the structure design is reasonable, and high-frequency vibration is easy to realize.
