The specific embodiment
Through embodiment the utility model is done further explain below in conjunction with accompanying drawing.
Like 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 the reference direction of hydraulic support in the drawings, 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; On one-level extensible canopy 2, be provided with one-level cover plate assembly 4; On secondary extensible canopy 3, be provided with secondary cover plate assembly 5, 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.
Two lateral surfaces at one-level cover plate assembly " ┌ ┐ " shape opening are provided with the slideway 41 along its length direction; Correspondingly; On two side plates of secondary cover plate assembly " ┌ ┐ " shape opening, be provided with pin shaft hole 51, be provided with bearing pin 6 in this pin shaft hole 51, this bearing pin 6 constitutes sliding pair with slideway 41.
The upper side that the upper side of one-level cover plate assembly front end is provided with wing type baffle plate 42, two step cap assemblies front ends is provided with wing type baffle plate 52.
The upper side of secondary cover plate assembly is provided with triangle domatic face 53; This triangle domatic face is along the length direction bisector plane of secondary cover plate assembly and is symmetrical set; Front end, its rear end that the front end of triangle domatic face is located at the secondary cap assemblies are pointed; Be positioned at the postmedian of secondary cover plate assembly; This triangle domatic face is the ridges structure downward-sloping to its both sides from office, secondary cover plate assembly length plane at secondary cover plate assembly width, and this triangle domatic face is by the shape that preceding recedes at secondary cover plate assembly length direction.This triangle domatic shape face reality is welded on secondary cover plate assembly upper side by two blocks of steel plates triangular in shape and constitutes.
The one-level cover plate assembly is formed by the steel plate welding, and the secondary cover plate assembly is formed by the steel plate welding.
The wing type baffle design of one-level cover plate assembly and secondary cover plate assembly front end prevents that foreign material such as spoil from falling into ramming mechanism.The foreign material such as the more convenient spoil of design of said secondary cover plate assembly triangle domatic are slipped on the base plate, thereby have protected ramming mechanism better.
The waste filling ramming mechanism is prevented the dirt band structure; Can reduce or increase the number of cover plate assembly according to actual conditions; Such as also adopting this anti-dirt band structure to ramming mechanism with one-level extensible canopy or three grades of extensible canopies; Every grade all interconnects synchronization telescope with the extensible canopies at different levels of correspondence, prevents that better spoil from getting into ramming mechanism, realizes filling better.And the sliding pair between the cover plate assembly also can adopt other form, such as roller and slideway, and the form of slide rail and slideway, its effect is the gathering for the ease of multistage cover plate assembly.
