Abstract
The invention belongs to the field of excavation apparatus fittings, and concretely relates to a mining adjustable cutting pick. The mining adjustable cutting pick comprises a cutter body, a cutter neck and a cutter head, a counter bore is arranged in the cutter body, a through hole is arranged in the cutter neck, the cutter head is inserted into the through hole of the cutter neck, an adjusting rod is arranged to the end portion of the cutter head, the adjusting rod stretches out of the counter bore and is threaded connection with a nut cover at the tail end of the cutter body, and a protection layer is arranged outside the cutter head. Less wearing of the cutter head is effectively guaranteed through adjusting arrangement and the arrangement of the protection layer, and after the cutter head is worn for a long term, the cutter head can be extended to realize continuous use without integral replacement.
Description
Technical field
The invention belongs to excavating equipment accessory field, specifically a kind of mining adjustable pick.
Background technology
Pick is a kind of cutting tool of the engineering machinery for ore extraction and coal mining activity, cylindrical or mushroom head carbide alloy is inlayed in cutter hub front end by its mechanism, cutter head body abrasion resistance near carbide alloy is less than carbide alloy, the wearing and tearing of this head position cause reduce the application life of pick, on the other hand, the whole pick of this cutter head body serious wear consequence entirety of having to is scrapped, and causes great waste, too increases cost of production simultaneously.
Summary of the invention
The object of this invention is to provide a kind of mining adjustable pick of one that can carry out telescopic adjustment according to pick wear condition.
The invention provides following technical scheme:
A kind of mining adjustable pick; it comprises cutter hub, cutter neck and cutter head; counterbore is provided with in described cutter hub; through hole is provided with in cutter neck; cutter head inserts in the through hole of cutter neck; cutter head end winding support has adjusting rod, and adjusting rod stretches out counterbore and is threaded with the nut cap of cutter hub tail end, and cutter head outside is provided with topping.
Described topping is fixed on cutter head outside and is separated setting with cutter neck.
Advantage of the present invention is few by the wearing and tearing arranging energy available protecting cutter head of adjustable setting and topping, can regulate simultaneously and extend the effect that cutter head reaches continuation use, do not need integral replacing after long term wear.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Detailed description of the invention
As shown in Figure 1; a kind of mining adjustable pick; it comprises cutter hub 1, cutter neck 2 and cutter head 3; counterbore is provided with in described cutter hub 1; be provided with through hole in cutter neck 2, cutter head 3 inserts in the through hole of cutter neck 2, and cutter head 3 end winding support has adjusting rod 4; adjusting rod 4 stretches out counterbore and is threaded with the nut cap 5 of cutter hub tail end, and cutter head 3 outside is provided with topping 6.
Described topping 6 is fixed on cutter head outside and is separated setting with cutter neck.
