The invention discloses a gas-liquid mixing type excitation system of cement pavement rubblization equipment. The gas-liquid mixing type excitation system comprises a hydraulic cylinder, a piston rod, an energy accumulator, a two-position three-way reversing valve, a hydraulic pump, an oil tank, a two-position two-way reversing valve and an overflow valve; the piston rod is provided with a piston; the piston is arranged inside a piston cavity inside the hydraulic cylinder and divides the piston cavity into a first piston cavity body and a second piston cavity body; a rubble tapping head is installed at the drive end of the piston rod; and the output end of the hydraulic pump and a pressure oil port P of the two-position three-way reversing valve are connected through a pressure oil channel in a liquid supplying mode. The gas-liquid mixing type excitation system of the cement pavement rubblization equipment has the advantages of being reasonable in structural design and free of a controller, reducing cost and improving 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 hybr...
