Abstract
The utility model discloses a high frequency breaking hammer head, which comprises a casing, a cutter row and a vibration exciting device. The vibration exciting device comprises a box body, two eccentric vibration exciting wheels arranged in the box body and a driving motor for driving the two eccentric vibration exciting wheels to perform reversing rotation at constant speed. The two eccentric vibration exciting wheels are vertically and symmetrically arranged relative to the vibration direction of the cutter row, and the cutter row is fixedly connected with the box body. When the high frequency breaking hammer head is used, centrifugal forces of the two eccentric vibration exciting wheels in the horizontal direction are offset mutually, centrifugal forces of the two eccentric vibration exciting wheels in the vertical direction form a resultant force to drive the cutter row to vibrate vertically. The vibration frequency can reach to 2000 times per minute, continuous breaking forces can be produced, and the work efficiency is three to five times of an existing breaking hammer. When the high frequency breaking hammer head is used for excavating and breaking shale, the work efficiency can reach to seven to eight times higher than before. In addition, the high frequency breaking hammer head uses a vibration reducing structure and a hydraulic motor, so that the energy-saving effect is good, and noise can be reduced below 75 decibels. The hammer head is superior in performance, cheap in price and capable of replacing imported products of the same type.
