Specific embodiment
The present invention is described in further detail below in conjunction with the drawings and specific embodiments.It should be appreciated that described herein
Specific embodiment be only used to explain the present invention, be not intended to limit the present invention.
As shown in Figure 1-3, envelope equipment is filled out in a kind of drilling of the present invention, including crushing mechanism 4 and connect with the crushing mechanism
The system for compacting 3 connect is equipped with elevating mechanism 2, the rotating power machine between the system for compacting 3 and revolving power mechanism 1
The power rail of structure is connect with the crushing cutter 41 of the crushing mechanism, the upper end of the elevating mechanism and the revolving power mechanism
Bottom it is hinged, lower end and the upper surface for stating system for compacting it is hinged, the power rail pass through the elevating mechanism, system for compacting
It is connect after the axis hole 32 in 3 squeeze board center with the crushing mechanism, corresponding hiding slot 32 is formed on the squeeze board, used
In in compacting operation that the crushing cutter 41 is corresponding hiding.
In the present invention, it is in that center is radial outward that the crushing cutter 41, which is multiple, horizontally disposed in same level,
It is fixed on the outer surface of mounting hole 40, can be three, four, even more than particular number is unlimited.Mounting hole 40 and power
Bar 10 is fixedly connected.
Wherein, the revolving power mechanism includes headstock 11, and the power motor 12 in the headstock is arranged in, described
Institute on gear 13 on 12 output shaft of power motor and the upper end gear mounting portion 15 for protruding into the power rail 10 in the headstock
The transmission gear 14 of installation engages, and power rail 10 is connect with headstock by bearing 16, broken when needing by the engagement of gear
When filler, start motor, driving power rail rotation rotates crushing cutter, to break the filler of contact using crushing cutter
It is broken, guarantee the effect of compacting.
Wherein, the elevating mechanism 3 includes two groups of scissors fork elevating bars 21, and is provided with driving mechanism 22 and is risen with controlling
Drop, the elevating mechanism are existing scissors fork elevating structure, and driving mechanism is electric cylinder, are in tilted layout, both ends and elevating mechanism
