Description
Technical field
The present invention relates to slag stone cleaning device of boring machine.
Background technology
Traditional development machine is when carrying out the tunneling construction operations such as massif or tunnel, the slag stone that produces is normally by after fixedly scraper bowl scoops up slag stone along several of periphery setting at bit pallet dorsal part, gradually inclination and upset when rotating to a high position successively with the bit pallet are poured on the slag stone in the scraper bowl on the conveyer belt of being located at bit pallet rear and are transported away backward.Because the width of conveyer belt is limited, therefore in the scarfing cinder process, the scraper bowl that slag stone is housed often also do not rotate to conveyer belt directly over the time, because it has been in skewedly, slag stone namely begins to slide out gradually, falls outside conveyer belt; And after directly over conveyer belt has been crossed in the scraper bowl rotation, the residue slag stone of not yet having toppled in the scraper bowl has also fallen continuing to topple over outside the opposite side at conveyer belt, thereby have a large amount of slag stone and fail to be seen off by conveyer belt, also need manually to assist cleaning, this has not only obviously reduced effect, and personnel carry out prune job under development machine, also have very large potential safety hazard.
Summary of the invention
The invention provides a kind of slag stone cleaning device of boring machine, the slag ground mass that when driving produces originally all can be disposed automatically, improved greatly operating efficiency and construction safety.
The basic structure of slag stone cleaning device of boring machine of the present invention is that front end at the bit pallet is provided with and creeps into diameter greater than the drill bit of its card diameter equally, is provided with the connecting gear that transports backward slag stone after the bit pallet.Wherein, the bit pallet be provided with by clearance space one can with development machine synchronous operation and above with the fixedly block structure of the sagittal plane extend type of opening, connecting gear connect below after the slag end is adjacent to the block structural openings.In the clearance space between bit pallet and block structure, along the axis of bit pallet one round platform or the terrace with edge structure coaxial with it is set.The lower bottom of round platform or terrace with edge structure (being larger diameter end) is fixed on the bit pallet, and the upper bottom of round platform or terrace with edge structure (being smaller diameter end) cooperates with the block structure interval.Be provided with the radially shovel slag structure of abduction of flap-like at round platform or terrace with edge structure, and make its radially parallel or oblique of central axis of flap-like plane and round platform or the terrace with edge structure of abduction, a kind of preferred mode is to make the plane of its flap-like along the bus of frustum cone structure or the incline setting of terrace with edge structure, and each flap-like radially abduction shovel slag structure round platform or terrace with edge structural extend axially length and round platform or terrace with edge structure up and down the axial length between two bottom faces equate, thereby can make with drill bit and creep into the slag stone that produces when after the shovel slag structure by flap-like scoops up and with the bit pallet, rotating, when not arriving the aperture position of block superstructure, all the time be installed in the shovel slag structure by this flap-like, the side of round platform or terrace with edge structure, and can not drop out in the formed clearance space of block structure, only when rotating to the aperture position of block superstructure, could all drop on the conveyer belt by the upper opening of block structure by the inclined side of round platform or terrace with edge structure, thereby avoided dropping outside the both sides of conveyer belt, reached basic energy and realized disposable with the clean purpose of slag stone complete liquidation.
In said structure, when adopting the terrace with edge structure, particularly preferably be and adopt positive terrace with edge structure.
The diameter of said block structure in the said apparatus usually can not be greater than the diameter of the maximum abduction rotation round of the drill bit on the bit pallet.Deposit the more slag stone of volume in order to take full advantage of above-mentioned clearance space, the rotation round diameter of the maximum abduction of drill bit is consistent or smaller on the diameter that preferably makes this block structure and the bit pallet.And, can also be arranged to the rotation round diameter of the abduction periphery of the structural flap-like shovel of round platform or terrace with edge slag structure consistent with the diameter of this block structure.
Further, along highly adapting, be more preferably it be consistent under the opening of the upper base radius of frustum cone structure or the upper base edge of terrace with edge structure and block structure, usually can with under the opening of the upper base of round platform or terrace with edge structure and block structure along contiguous setting.
Result of the test shows that making the bus of said this frustum cone structure in the said structure or the side of terrace with edge structure and the angle of round platform or terrace with edge structure axis is 45 °, namely is conducive to toppling over of slag stone, also has and is convenient to its processing and manufacturing.
In the said structure, the quantity of said flap-like shovel slag structure can according to circumstances arrange, under extreme case even only arrange one and also be fine.Test shows that in order to improve the cleaning efficiency of slag stone, a kind of selectable scheme is for being set at least two with this flap-like shovel slag structure, and better mode is to be set to 4.
In the set-up mode of above-mentioned said flap-like shovel slag structure, its cross section periphery along round platform or terrace with edge structure is arranged in equally spaced mode, be conducive to make slag stone at each clearance space by uniform distribution, it is stressed also more balanced to turn round.
On the said structure basis, for giving full play to the effect of each parts, reduce cost, simplified structure and weight can also make in the said structure said this round platform or terrace with edge structure hold concurrently as the driving shaft that is used for driving the rotation of bit pallet simultaneously.
Be appreciated that thus, the slag stone cleaning device of boring machine of said structure form of the present invention, the slag stone that produces in the time of can making the drill bit driving can be by the inclined plane of round platform or terrace with edge structure, all concentrated to incline by the upper opening of block structure and drop on the conveyer belt, realized substantially all disposing slag stone is disposable, need not the human assistance cleaning, significantly improved operating efficiency, also guaranteed greatly personnel's safety.
Below by the specific embodiment by the accompanying drawing illustrated embodiment, foregoing of the present invention is described in further detail again.But this should be interpreted as that the scope of the above-mentioned theme of the present invention only limits to following example.Do not breaking away from the above-mentioned technological thought situation of the present invention, various replacements or change according to ordinary skill knowledge and customary means are made all should comprise within the scope of the invention.
