Abstract
The utility model discloses one kind to be based on minor diameter hard rock push-bench cutterhead hobboing cutter girff structure, including spoke disk, double-edged hobbing cutter, piecemeal girff and girff component, there are two the spoke disk settings, and installation cavity is formed between spoke disk, the girff component includes double-edged hobbing cutter and piecemeal girff, and girff component be provided with it is multiple, it is connected with each other between multiple girff components, there are two the piecemeal girff settings, the double-edged hobbing cutter is mounted on two piecemeal girff middle positions, and it is welded and fixed and connect on the inside of the outside of piecemeal girff and spoke disk；The utility model, in a limited space in, improve a lot before solid cutter aperture opening ratio ratio, to effectively increase the mobile performance of dregs, rubble, while the reduction of overall dimensions, corresponding material and processing cost are also reduced.
Description
Technical field
The utility model relates to push-bench apparatus fields, specially a kind of to be based on minor diameter hard rock push-bench cutterhead hobboing cutter knife
Box structure.
Background technique
It is more and more to the needs of push-bench with the development of national underground pipe network.China region is vast, engineering geology and
Hydrogeologic condition is considerably complicated, and push pipe is applied on various stratum, such as weak soil, mud, sandy gravel and rock.It is domestic at present small
The rock push-bench of diameter is more and more, and enhancing efficiency of breaking rock, hobboing cutter quantity can all maximize arrangement；But in limited sky
Between in, what is generally stored is all standard entirety girff, and number of cutters increases, and corresponding cutterhead aperture opening ratio is much less instead, no
Conducive to the receipts slag of timely slag input and scraper, can also secondary abrasion be generated to cutter in this way, once construction formation variation, encounters mud
The cutterhead of soil, small aperture opening ratio is easier mud lining, influences construction speed, therefore we design one kind based on minor diameter hard rock push pipe
Machine knife disk hobboing cutter girff structure is necessary.
Utility model content
The purpose of this utility model is to provide one kind to be based on minor diameter hard rock push-bench cutterhead hobboing cutter girff structure, is mentioning
High cutterhead aperture opening ratio reduces disintegrating slag to the secondary abrasion of hobboing cutter, improves dregs mobility, have in terms of saving material and processing cost aobvious
Work advantage.
The purpose of this utility model can be achieved through the following technical solutions:
One kind being based on minor diameter hard rock push-bench cutterhead hobboing cutter girff structure, including spoke disk, double-edged hobbing cutter, piecemeal knife
Case and girff component, there are two the spoke disk settings, and installation cavity, the girff component packet are formed between spoke disk
Include double-edged hobbing cutter and piecemeal girff, and girff component is provided with multiple, is connected with each other between multiple girff components, described point
There are two the settings of block girff, and the double-edged hobbing cutter is mounted on two piecemeal girff middle positions, and piecemeal girff is outer
It is welded and fixed and connect on the inside of side and spoke disk.
The utility model has the beneficial effects that by spoke disk, double-edged hobbing cutter and piecemeal girff splicing synthesis girff component,
Instead of original standard entirety girff, in a limited space in, improved before solid cutter aperture opening ratio ratio it is very much, thus effectively
Increase the mobile performance of dregs, rubble, while the reduction of overall dimensions, corresponding material and processing cost also reduce.
Detailed description of the invention
In order to facilitate the understanding of those skilled in the art, the utility model will be further described below with reference to the accompanying drawings.
Fig. 1 is the utility model overall structure diagram；
In figure: 1, spoke disk；2, double-edged hobbing cutter；3, piecemeal girff.
Specific embodiment
The technical solution of the utility model is clearly and completely described below in conjunction with embodiment, it is clear that described
Embodiment be only the utility model a part of the embodiment, instead of all the embodiments.Based on the reality in the utility model
Example is applied, all other embodiment obtained by those of ordinary skill in the art without making creative efforts all belongs to
In the range of the utility model protection.
As shown in Figure 1, a kind of be based on minor diameter hard rock push-bench cutterhead hobboing cutter girff structure, including spoke disk 1, twolip
Hobboing cutter 2, piecemeal girff 3 and girff component, there are two the settings of spoke disk 1, and installation cavity, knife are formed between spoke disk 1
Box assembly includes double-edged hobbing cutter 2 and piecemeal girff 3, and girff component is provided with multiple, is connected with each other between multiple girff components,
There are two the settings of piecemeal girff 3, and double-edged hobbing cutter 2 is mounted on two 3 middle positions of piecemeal girff, and the outside of piecemeal girff 3
It is connect with being welded and fixed on the inside of spoke disk 1.
Working principle of the utility model is: passing through spoke disk 1, double-edged hobbing cutter 2 and the splicing synthesis girff group of piecemeal girff 3
Part, instead of original standard entirety girff, in a limited space in, improved before solid cutter aperture opening ratio ratio it is very much, thus
The mobile performance of dregs, rubble, while the reduction of overall dimensions are effectively increased, corresponding material and processing cost also reduce.
The preferred embodiment in the utility model disclosed above is only intended to help to illustrate the utility model.Preferred embodiment is simultaneously
There is no the details that detailed descriptionthe is all, also not limiting the utility model is only the specific embodiment.Obviously, according to this theory
The content of bright book can make many modifications and variations.These embodiments are chosen and specifically described to this specification, is in order to preferably
The principles of the present invention and practical application are explained, so that skilled artisan be enable to better understand and utilize this
Utility model.The utility model is limited only by the claims and their full scope and equivalents.
