It is interior, it is clamped with the first card slot 7 so that interlocking lever 17 can not rotate due to passing through limited block 9 on the left of interlocking lever 17, it is ensured that third card
Then slot 18 and kelly 20 only need to be such that kelly 20 snaps fit onto third card slot 18, just can reach fixed company in same vertical line
Lever 17 reaches the tamping operation to the earthwork so that crushing head main body 1 is able to drive the up and down motion of hammer ram 12, saves another
The fund of ballast consolidating machine is purchased outside, saves construction cost purpose.
In conclusion this is used for the excavator crushing head of earthwork compacting, by the way that the protective plate 4 connecting with telescopic rod 3 is arranged,
Be fixedly connected by telescopic rod 3 with connecting plate 2 when crushing head main body 1 works due to protective plate 4 so that protective plate 4 always with
Ground face contact, simultaneously because protective plate 4 is transparent plastic sheet, does not interfere with constructor so as to intercept the stone of splashing
Member's observation construction progress, to achieve the purpose that effectively to avoid the stone splashing in broken stone to accidentally injure construction personnel.
Also, the motion bar 11 being slidably connected by setting with fixed plate 10 need to only make activity when carrying out crushing operation
11 upward sliding of bar is located at same level until the first fixed block 23 and the second fixed block 24, and then rotating threaded rod 25 makes spiral shell
Rasp bar 25 runs through the first fixed block 23, to reach the fixation to motion bar 11 and hammer ram 12, hammer ram 12 is avoided to influence broken make
Industry makes when carrying out earthwork tamping operation, and need to only rotate threaded rod 25 makes threaded rod 25 and the first fixed block 23 be detached from clamping, then
12 slide downward of motion bar 11 and hammer ram, then by construction personnel first in the first card slot 7 of insertion of interlocking lever 17 and extruding the
One spring 8 so that can be snapped fit on the right side of interlocking lever 17 in second card slot 15, due to pass through on the left of interlocking lever 17 limited block 9 with
First card slot 7 is clamped so that interlocking lever 17 can not rotate, it is ensured that third card slot 18 and kelly 20 are in same vertical line, then only
Kelly 20 need to be made to snap fit onto third card slot 18, just can reach fixed interlocking lever 17, so that crushing head main body 1 is able to drive
Hammer ram 12 moves up and down, and reaches the tamping operation to the earthwork, saves the fund in addition purchasing ballast consolidating machine, saves construction cost mesh
, so that effective solution at present generally requires to clear up in the earthwork by installing crushing head to excavator in construction
The stone of floating, but splash during the stone that cleaning is floated since crushing head shock may cause stone, to accidentally injure
To the construction personnel of surrounding, while also needing to tamp ground after cleaning out, but hand compaction is time-consuming and laborious, and
Buy the problem of special ramming machine will increase construction cost.
It although an embodiment of the present invention has been shown and described, for the ordinary skill in the art, can be with
A variety of variations, modification, replacement can be carried out to these embodiments without departing from the principles and spirit of the present invention by understanding
And modification, the scope of the present invention is defined by the appended.
