The specific embodiment
The present invention is described in further detail by embodiment below in conjunction with accompanying drawing.
Such as Fig. 1, Fig. 2, Fig. 3, Fig. 4, Fig. 5, Fig. 6, Fig. 7, Fig. 8, Fig. 9 and shown in Figure 10.Continue to use in the drawings the reference direction of hydraulic support, before the left side is among the figure, after right-hand member is.In the present embodiment, be provided with balance arm 1 and extensible canopy in this waste filling ramming mechanism, be provided with one-level extensible canopy 2 and secondary extensible canopy 3 in this spoil ramming mechanism, be provided with one-level cover plate assembly 4 at one-level extensible canopy 2, be provided with secondary cover plate assembly 5 at secondary extensible canopy 3, the main body of this one-level cover plate assembly 4 and secondary cover plate assembly 5 is " ┌ ┐ " shape hatch frame, and the distance between two medial surfaces of secondary cap assemblies " ┌ ┐ " shape opening is greater than the width of one-level cover plate assembly " ┌ ┐ " shape opening.
Be provided with slideway 41 along its length direction at two lateral surfaces of one-level cover plate assembly " ┌ ┐ " shape opening, correspondingly, two side plates at secondary cover plate assembly " ┌ ┐ " shape opening are provided with pin shaft hole 51, are provided with bearing pin 6 in this pin shaft hole 51, and this bearing pin 6 consists of sliding pair with slideway 41.
