Right coal-cutting drum；Be provided with damper mechanism on bottom bracket, the damper mechanism be separately positioned on left cutting machine and intermediate box it
Between between right cutting units and intermediate box, every group of damper mechanism includes left push pedal and right push pedal, is pushed away in left push pedal and the right side
The relative inner of plate is provided with buffer bar, and buffer spring is provided between two buffer bars, the outside between two buffer bars
Impact-absorbing shell is provided with, in the flexible pearl of the inner surface setting of left push pedal and right push pedal.
As preferred scheme of the present utility model, right buffer bar front end is provided with sleeve pipe, buffer spring right-hand member is extend into
In sleeve pipe.
As preferred scheme of the present utility model, right buffer bar front portion is fixed on the right side of the impact-absorbing shell, it is left in impact-absorbing shell
Side is provided with preformed hole, and left buffer bar front end is movably arranged in preformed hole.
As preferred scheme of the present utility model, four elastic cement buffers are horizontally arranged with impact-absorbing shell, elasticity
Daub buffer is distributed in outside of sleeve.
It is that the coal-winning machine can be by during coal mining that the utility model, which can reduce the advantages of coal mining machine of vibratory impulse,
Caused vibration carries out effective weaken and buffered, and coal-winning machine internal part is protected.
Brief description of the drawings
Fig. 1 is the utility model front view.
Fig. 2 is damper mechanism structural representation.
Embodiment
As shown in drawings, the utility model can reduce the coal mining machine of vibratory impulse, including intermediate box 1, in intermediate box 1
