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.

Description

High frequency quartering hammer tup

Technical field

The utility model relates to engineering machinery field, particularly a kind of parts of quartering hammer.

Background technology

Quartering hammer is a kind of engineering machinery that is used for rock excavation or crushing operation, it can be in engineering construction can more effective broken stone and rock, increase work efficiency.Existing quartering hammer tup is generally the fluid pressure type tup, promptly directly is that power passes through the reciprocating motion that piston is realized drill steel with hydraulic pressure, realizes the fragmentation to rock; This just causes the frequency of impact of complex structure, tup of existing quartering hammer lower; Because higher frequency of impact could produce continuous power to reach higher crushing efficiency, therefore, the operating efficiency of existing quartering hammer tup is lower; Simultaneously, also there is certain deficiency in existing quartering hammer tup aspect noise and the energy consumption control.

To above-mentioned deficiency, need existing quartering hammer tup is improved, to improve its operating efficiency, reduce its noise and make it more energy-conservation.

The utility model content

In view of this, the utility model provides a kind of high frequency quartering hammer tup, and this quartering hammer tup is through the dither of mechanical oscillation mechanism realization quartering hammer blade row, and simple in structure, vibration frequency is high, can reach the purpose that improves the quartering hammer operating efficiency.

The high frequency quartering hammer tup of the utility model; Comprise that housing, an end stretch in the housing and can reciprocating along the vertical direction blade row and be arranged in the housing and produce the exciting device of dither up and down; Two barycenter that said exciting device comprises casing, be arranged in the casing depart from the excitation wheel of rotating shaft and are used to drive two counter-rotational CD-ROM drive motors of excitation wheel constant speed; Said two excitation wheels are symmetrical set with respect to the vertical of blade row direction of vibration, and said blade row is fixedly connected with casing.

Further, be provided with vibration damping noise damper I between said casing and the housing, be provided with vibration damping noise damper II between said blade row top and the housing;

Further, said vibration damping noise damper I is a rubber pneumatic bag, and said vibration damping noise damper II is a block rubber;

Further, said CD-ROM drive motor is a hydraulic motor.

The beneficial effect of the utility model: the high frequency quartering hammer tup of the utility model; Comprise that housing, an end stretch in the housing and can reciprocating along the vertical direction blade row and be arranged in the housing and produce the exciting device of dither up and down, two barycenter that said exciting device comprises casing, be arranged in the casing depart from the excitation wheel of rotating shaft and are used to drive two counter-rotational CD-ROM drive motors of excitation wheel constant speed, and said two excitation wheels are symmetrical set with respect to the vertical of blade row direction of vibration; Said blade row is fixedly connected with casing; During use, two eccentricity excitation wheels centrifugal force is in the horizontal direction cancelled out each other, and with joint efforts blade row is driven in the centrifugal force formation of vertical direction; Realize the up-down vibration of blade row; Its vibration frequency can be reached 2000 times/minute by the rotating speed decision of excitation wheel, and its operating efficiency is 3～5 times of existing quartering hammer; Be used for shale is excavated when broken its operating efficiency even can reach 7～8 times; In addition, the utility model uses vibration-proof structure and hydraulic motor, good energy-conserving effect, and noise can be reduced to below 75 decibels.
