Compared with prior art, the advantages of drill bit protective cover of this drill carriage, is：Can effectively it be stopped by cover body
Slungshot, and cover body only drill bit stretch out work when just open, need not open pound when, cover body automatic drawing back.
Description of the drawings
Fig. 1 is that cover body provided by the utility model opens schematic diagram.
Fig. 2 is that cover body provided by the utility model folds schematic diagram.
In figure, cover body 1, drill bit 2, drilling pipe 3, gauze 4, strut 5, bearing 6, branch hole 7, casing 8, spacing ring 9, curved bar 10.
Specific implementation mode
The utility model is described in more detail with reference to the accompanying drawings and detailed description.
As shown in Figs. 1-2, the drill bit protective cover of this drill carriage includes the cover body 1 being arranged on drill bit assembly, the cover body 1
Expansible folds, and the drill bit assembly includes the drilling pipe 3 for retracing drill bit 2, and the drill bit 2 is extended or withdraws drilling pipe 3,
When the drill bit 2 stretches out drilling pipe 3, the cover body 1 opens.Cover body 1 includes being circumferentially provided in drilling pipe 3 and in umbrella
Gauze 4, the gauze 4 is interior to be equipped with skeleton.Skeleton is made of several struts 5 being radially arranged on 3 outer wall of drilling pipe, described
3 outer wall of drilling pipe be circumferentially with 5 one-to-one bearing 6 of strut, one end of the strut 5 is articulated on bearing 6 and bearing 6
It is interior to be equipped with torsional spring so that strut 5 is opened by the elastic force of torsional spring.6 top of bearing have with 6 one-to-one branch hole 7 of bearing,
The inner end of the strut 5 is extended to by branch hole 7 in drilling pipe 3.2 outside of drill bit is equipped with casing 8, and drive sleeve is equipped in drill carriage
8 axial movements are in the driving motor in drilling pipe 3, and 8 bottom of casing is less than at branch hole 7, when the casing 8 is moved to branch
At hole 7 and when the inner end of strut 5 is ejected drilling pipe 3 to the outer wall of casing 8 from branch hole 7, the strut 5 is turned to close to drilling pipe
3 outer walls.Due to the effect of torsional spring in bearing 6 so that the opening of strut 5 and 3 outer wall of drilling pipe are in about 45 ° of angle under normal conditions, from
And strut gauze 4, for keeping out slungshot, to avoid threat of the slungshot to operating personnel and equipment.
As shown in Figure 1, the curved bar 10 of the inner end of strut 5 is entered from branch hole 7 in drilling pipe 3, at this point, under casing 8 is located at
Side and the top of casing 8 are less than the position in branch hole 7, therefore strut 5 can still open.
As shown in Fig. 2, when excavating work terminates, drill bit 2 is withdrawn, and casing 8 is inwardly withdrawn at this time, and is moved at branch hole 7
When by curved bar 10 eject drilling pipe 3 in so that curved bar 10 returns to inside branch hole 7, torsional spring is forced to compress at this time, then strut 5 receive
It is back to close with the outer wall of drilling pipe 3, gauze 4 also recycles therewith at this time, then cover body 1 is packed up spare.
Further, the position limiting structure of the shaft orientation moving range in drilling pipe 3 of limiting boot 8 is equipped in drilling pipe 3.Position limiting structure
Including two spacing rings 9 being arranged on 3 inner wall of drilling pipe, branch hole 7 is less than casing 8, branch hole 7 at a distance from the spacing ring 9 on top
With at a distance from the spacing ring 9 of lower part be more than casing 8.Spacing ring 9 can effective limiting boot 8 moving range, avoid casing 8 from existing
Drilling pipe 8 is removed when moving down；And excessively moved when moving up and so that curved bar 10 turns again in drilling pipe 3.
The specific embodiments described herein are merely examples of the spirit of the present invention.The utility model institute
Belonging to those skilled in the art can make various modifications or additions to the described embodiments or using similar
Mode substitute, but without departing from the spirit of the present application or beyond the scope of the appended claims.
Although be used more herein cover body 1, drill bit 2, drilling pipe 3, gauze 4, strut 5, bearing 6, branch hole 7, casing 8,
The terms such as spacing ring 9, curved bar 10, but it does not preclude the possibility of using other terms.The use of these items is only for more
Easily describe and explain the essence of the utility model；It is new with this practicality to be construed as any one of the additional limitations all
Type spirit is disagreed.
