Abstract
The utility model discloses an alloy cutter head of a cutting pick of a coal cutter, which is composed of a cutter head and a cutter handle, wherein, the cutter head and the cutter handle are assembled into an integral part, and are both cylindrical. The diameter of the cutter handle is smaller than that of the cutter head. The cutting surface of the cutter head is in a rectangular pyramid shape, and the cutter handle is connected with the cutting pick tightly through the way of hot pressing. The utility model has the characteristics of simple structure, reasonable design, convenient installation, firmness and reliability. Coal cut by the utility model is usually granular. The utility model greatly improves the yield rate of clean coal, does not generate dust easily, and enhances the security of operation. The utility model is suitable for the installation and the use of the cutting picks of various coal cutters.
Description
Technical field
The utility model relates to the alloy cutter head of the pick of coal-winning machine, particularly a kind of coal winning machine cutting bit.
Background technology
At present, employed alloy cutter head on coal winning machine cutting bit, its cut surface mostly are conical.The greatest drawback of this alloy cutter head is that broken end is more in the coal that is cut, and greatly reduces the output capacity of cleaned coal; And be easy to generate dust, cause gas explosion; In addition, this alloy cutter head is for being welded on the pick, and is insecure, very easily comes off in the operation.
Summary of the invention
Goal of the invention of the present utility model is to provide a kind of alloy cutter head that can overcome a kind of coal winning machine cutting bit of above-mentioned defective preferably.
The technical solution of the utility model is such, a kind of alloy cutter head of coal winning machine cutting bit, and it is made up of cutter head and handle of a knife two parts; Cutter head and handle of a knife are as a whole, and are cylindrical, and the diameter of handle of a knife is less than cutter head; The cut surface of cutter head is the four sides pyramid; Handle of a knife closely is connected with pick by hot pressing mode.
Characteristics of the present utility model are, and are simple in structure, reasonable in design, easy for installation, solid and reliable.The coal that is cut down mostly is graininess, has improved the output capacity of cleaned coal greatly, and is not easy to produce dust, has improved the safety of operation, can be fit to installing and using of various coal winning machine cutting bits.
Description of drawings
Fig. 1 looks schematic diagram for a kind of alloy cutter head master of coal winning machine cutting bit; Wherein: 1 cutter head, 2 handle of a knifes, 3 cut surfaces.
Fig. 2 looks schematic diagram for an a kind of alloy cutter head left side of coal winning machine cutting bit.
The specific embodiment
Understand the alloy cutter head of existing a kind of coal winning machine cutting bit of accompanying drawings for goal of the invention of the present utility model, feature and technique effect being had more clearly.
By accompanying drawing 1 to 2 as seen, a kind of alloy cutter head of coal winning machine cutting bit, it is made up of cutter head 1 and handle of a knife 2 two parts; Cutter head 1 and handle of a knife 2 are as a whole, and are cylindrical, and the diameter of handle of a knife 2 is less than cutter head 1; The cut surface 3 of cutter head 1 is the four sides pyramid; Handle of a knife 2 closely is connected with pick by hot pressing mode.
