The invention discloses an electro-hydraulic vibration exciter for cement pavement crushing equipment, which is characterized in that it includes a hydraulic cylinder, a piston rod, a rotary valve, a hydraulic pump, an oil tank and an overflow valve, and the hydraulic cylinder piston The rod is provided with a piston, which slides and is arranged in the piston cavity in the hydraulic cylinder, and the piston separates the piston cavity into the first cavity of the piston and the second cavity of the piston, and gravel is installed on the driving end of the piston rod Hit the head, the direction control port A of the rotary valve is connected to the first chamber of the piston for liquid supply, the output end of the hydraulic pump is connected to the pressure oil port P of the rotary valve through a pressure oil channel, and the oil return of the rotary valve Port T is connected to the liquid return of the oil tank, and the pressure oil passage is connected to the side connection of the second chamber of the piston for liquid supply, and the bypass point of the pressure oil passage is also connected to the liquid supply of the overflow valve. P and the oil return port T are alternately connected to the direction control port A, thereby driving the hydraulic cylinder piston to reciprocate in the oil cylinder. The invention has the advantages of reasonable structural design and easy realization of high-frequency vibration.
Description
technical field [0001] The invention belongs to the field of road maintenance engineering machinery, and relates to an electro-hydraulic excitation system of cement pavement resonance crushing equipment. Background technique [0002] In the prior art, a vibratory hammer is generally used for the crushing operation of the cement pavement, and the vibratory hammer uses the vibration of the eccentric wheel driven by a motor to impact the crushing operation on the cement pavement. The problem with this type of transmission vibratory hammer is that the vibration stroke generated by the eccentric wheel is small and the impact force is not large, and because the speed of the eccentric wheel cannot be greatly increased in this structure, it is very difficult to achieve high-frequency vibration and the cost is very high. high. Contents of the invention [0003] The technical problem to be solved by the embodiments of the present invention is to provide an electro-hydraulic exciter...
