Abstract
The present invention relates to the coal mine roadway road heading machinery, be specially cutting head structure of tunneling machine, cutterhead is connected in packing base rear end portion by bolt with the packing seat of development machine, and packing base rear end portion is equipped with removable wear plate.The pick box that has been arranged by spiral on the cutterhead periphery is equipped with pick on pick box, be welded with junction plate at the pick box and the pick back side, and detachable stock guide is installed at the junction plate back side.Using this cutterhead structure can make the wearing plate at packing seat cylindrical rear portion and the stock guide of cutterhead external surface be convenient to dismounting, change at any time.The present invention can solve the problem (particularly cut half coal petrography and total rock) of existing cutting head of roadheader serious wear in the cut process.
Description
Technical field
The present invention relates to the coal mine roadway road heading machinery, be specially cutting head structure of tunneling machine, use this cutterhead structure and can make the wearing plate at packing seat cylindrical rear portion and the stock guide of cutterhead external surface be convenient to dismounting, change at any time.
Background technology
At present, development machine is one of capital equipment of mining machinery, and cutterhead is the development machine main execution unit in when work.When development machine was worked, cutterhead was used for the cut rock, was main stressed member.In actual application, owing to work long hours, be positioned at the stock guide serious wear of pick and pick box back, thereby the wearing and tearing of pick box and pick are quickened, seriously influenced the cut efficient of development machine; Be positioned at the wearing plate of packing seat rear portion periphery, serious wear and cause the bolt that connects cutterhead and packing seat is ground away in use, and then cause cutterhead to come off.And after the wearing plate heavy wear at stock guide and packing seat cylindrical rear portion, be difficult for repairing, therefore had a strong impact on the operating efficiency of development machine, bring very big trouble to the user.
Summary of the invention
The object of the present invention is to provide a kind of cutting head structure of tunneling machine, solve after the problem (particularly cut half coal petrography and total rock) of existing cutting head of roadheader serious wear in the cut process or the vulnerable part heavy wear the not problem of easy-maintaining, replacing.
Technical scheme of the present invention is:
A kind of cutting head structure of tunneling machine comprises wearing plate, packing seat, cutting head, pick, pick box, stock guide, and cutterhead is connected in packing base rear end portion by bolt I with the packing seat of development machine, and packing base rear end portion is equipped with removable wear plate; Cutterhead, packing seat and removable wear plate are connected by bolt II; The pick box and the pick back side are welded with junction plate, and stock guide is installed at the junction plate back side.
Described cutting head structure of tunneling machine, stock guide are detachable stock guide.
Described cutting head structure of tunneling machine, removable wear plate are arc, and the multistage arc is combined into the circle structure.
Described cutting head structure of tunneling machine, removable wear plate cross section are right angle type, and two faces of right angle type lay respectively at the rear end face and the lateral surface of packing seat.
Described cutting head structure of tunneling machine, the pick box that has been arranged by spiral on the cutterhead periphery is equipped with pick on pick box.
Described cutting head structure of tunneling machine, detachable stock guide is connected with junction plate by stop washer, bolt III.
The invention has the beneficial effects as follows:
1, the present invention has changed the connected mode of the wearing plate at the connected mode of the stock guide that is arranged by spiral on the connected mode, cutterhead external surface of original cutting head of roadheader and main frame and packing seat cylindrical rear portion, can make cutterhead (particularly half coal petrography and rock) when the cut by the present invention, vulnerable part for ease of maintenaince, change, significantly improve the bonding strength of cutterhead and complete machine, improved the reliability that complete machine uses.
When 2, using the wearing plate serious wear that the present invention can make vulnerable part stock guide on the cutterhead and packing seat cylindrical rear portion, dismounting at once is convenient to change; The connected mode of using cutterhead of the present invention and packing base rear end face can be improved the problem of original use cutterhead and this connected mode leading portion of cut main shaft bolt serious wear.
