Abstract

The invention discloses a high-frequency breaking hammer which comprises an installation shell, a vibration exciter, a four-bar mechanism and a vibration knife bar, wherein the vibration exciter comprises a shell, a first drive shaft arranged in the shell, a first driven shaft mutually meshed with the first drive shaft through a gear, a second drive shaft, a second driven shaft mutually meshed with the second drive shaft through a gear, and a bridging shaft arranged between the first drive shaft and the second drive shaft, wherein a first drive motor and a second drive motor are respectively arranged at one ends of the first drive shaft and the second drive shaft; central axes of the first drive shaft and the second drive shaft are positioned on the same vertical surface; and the first drive shaft, the first driven shaft, the second drive shaft and the second driven shaft are positioned on the same horizontal plane. According to the high-frequency breaking hammer, two groups of drive shafts are adopted and are matched with two drive motors; and compared with a breaking hammer driven by one motor, the high-frequency breaking hammer has the advantages of large breaking force, high breaking precision, small noise and strong breaking capability, thereby prolonging the working time of the breaking hammer and increasing the breaking efficiency.

Description

technical field

[0001] The invention relates to a high-frequency breaking hammer, in particular to a high-frequency breaking hammer. Background technique

[0002] Breaking hammer is a physical crushing equipment that integrates mechanical hydraulics, digital signals, and digital monitoring. The teeth of the breaking hammer can generate impact force on objects under the action of a vibration exciter, and then achieve crushing. A general breaking hammer is driven by a hydraulic motor to rotate the eccentric wheel, thereby generating a centrifugal force F, whose vertical component Fsinwt is a periodically changing disturbance force, which causes the shaft to generate radially forced vibration pressure, which is called the excitation force, and then by the excitation force The box of the vibrator transmits the vibration to the cutter teeth for crushing.

[0003] The existing vibrator only has a single motor for driving. When encountering some difficult-to-break objects, it will...
