Abstract
The utility model discloses a hard rock cutting pick, and aims to provide an improved head rock cutting pick. The hard rock cutting pick comprises a pick handle and a pick head, wherein the pick handle is integrally forged with the pick head; and an alloy head is welded at the top of the pick head. The hard rock cutting pick is characterized in that the diameter of the top of the pick head is 32-33 mm, and the vertical height of the pick head is 80-82 mm. The hard rock cutting pick is mainly used for cutting hard rock in a coal mine.
Description
Technical field
The utility model relates to a kind of pick, relates in particular to a kind of hard rock pick.
Background technology
The cutter of mining machinery cutting coal and rock comprises flat pick, conical pick and tangential pick, traditional pick, its tooth crown section diameter generally is no more than 30mm, tooth head vertical height is no more than 75mm, shortcoming be not wear-resisting, consume is large, cost is high.
Summary of the invention
Be to provide a kind of improved hard rock pick, to overcome above-mentioned shortcoming order of the present utility model.
For achieving the above object, technical solution of the present utility model is: a kind of hard rock pick comprises tooth handle and tooth head, tooth handle and tooth head forge in aggregates, and the top of tooth head is welded with alloy head, it is characterized in that: tooth head 2 top diameters are 32-33mm, and the vertical height of tooth head 2 is 80-82mm.
The beneficial effects of the utility model are: because tooth crown section wider (diameter is 32-33mm), and vertical height higher (80-82mm), thereby the contact surface of it and rock is larger, and it is slower to wear and tear, and cost is relatively low.
Description of drawings
Accompanying drawing is structural representation of the present utility model.
Among the figure: 1-tooth handle, 2-tooth head, 3-alloy head, 4-tooth crown section diameter, 5-tooth head vertical height.
The specific embodiment
Below in conjunction with accompanying drawing the utility model and the specific embodiment thereof are described in further detail.
Referring to accompanying drawing, the utility model comprises tooth handle and tooth head, and tooth handle and tooth head forge in aggregates, and the top of tooth head is welded with alloy head, it is characterized in that: tooth head 2 top diameters are 32-33mm, and the vertical height of tooth head 2 is 80-82mm.
Through forging molding, make tooth head 2 and tooth handle 1 become an integral body in round steel, tooth crown section diameter 4 is for example 32 or 33mm, and tooth head vertical height is for example 80 or 81 or 82mm.Tooth handle and tooth head use 20Cr2Ni4A high-quality steel.Alloy head uses diamondite.
