The invention discloses a gas-liquid hybrid excitation system for cement pavement crushing equipment, which includes a hydraulic cylinder, a piston rod, an accumulator, a two-position three-way reversing valve, a hydraulic pump, an oil tank, and a two-position two-way valve. A reversing valve and an overflow valve, the piston rod is provided with a piston, the piston is slidably disposed in the piston cavity in the hydraulic cylinder, and the piston separates the piston cavity into a first piston cavity and a second piston cavity, A gravel hammer is installed on the driving end of the piston rod; the output end of the hydraulic pump is connected to the pressure oil port P of the two-position three-way reversing valve through a pressure oil channel for liquid supply. The invention has the advantages of reasonable structural design, no need for a controller, cost saving and increased reliability.
Description
technical field [0001] The invention belongs to the field of road maintenance engineering machinery, and relates to a gas-liquid hybrid vibration 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 a gas-liquid hybrid...
