In the current high-frequency breaking hammer use, because the principle of the high-frequency breaking hammer is that a hydraulic motor drives an eccentric block to rotate to generate exciting force, the exciting force enables an exciting box to vibrate up and down, and therefore a cutter row and cutter teeth are driven to do work on rock, and the purpose of breaking the rock is achieved. Through the research of the inventor, the phenomenon of idle striking of the high-frequency breaking hammer is frequently caused by the fact that rock is cracked in construction, because no rock is propped against the tooth tip, the high-frequency breaking hammer can continuously strike the damping block when idle striking, so that the damping block is damaged too fast, and normal operation of the high-frequency breaking hammer is affected.
Referring to fig. 1 to 4, the high frequency breaking hammer 100 and the tunneling apparatus according to the embodiments of the present invention can solve the above-mentioned problems, and will be described in detail.

This high frequency breaking hammer 100 takes place to vibrate through vibration excitation piece 110 and drives the tooth point to hit rock, and when the rock breakage took place to beat the phenomenon in the sky, vibration piece 110 can produce to beat the extrusion to cushioning piece 120, and cushioning piece 120 drives brake piece 130 and vibration piece 110 contact through telescopic movement under this extrusion effect for vibration piece 110 slows down the beat extrusion action of cushioning piece 120, avoids because taking place to beat in the sky and causes the part damage, prevents to produce negative effect to the normal operation of high frequency breaking hammer 100.
In addition, the shock absorbing, buffering and braking actions of the shock excitation member 110 can be realized by arranging the buffer member 120 and the brake member 130, so that the arrangement of shock absorbing blocks in the prior art can be replaced or reduced.
In addition, with respect to the first damper 190, a second damper 180 is disposed at the other side of the vibration exciter 110, and the second damper 180 is configured to cooperate with the first damper 190 to jointly achieve a buffering and damping effect on the vibration exciter 110. The second vibration absorbing member 180 is specifically a vibration absorbing airbag, which can absorb the vibration of the vibration absorbing member 110 by filling or contracting itself.

In this embodiment, the first supporting rod 122 and the second supporting rod 123 are vertically arranged, and by limiting the extending directions of the two, the movement direction conversion can be realized through the first supporting rod 122 and the second supporting rod 123 under the condition that the movable stroke of the first supporting rod 122 is limited, and then the second supporting rod 123 drives the brake member 130 to contact with the exciting member 110, so as to realize rapid shock absorption of the exciting member 110.
