Abstract
The utility model discloses an antiskid spoon-shaped tooth designed under a hard alloy. According to the antiskid spoon-shaped tooth designed under the hard alloy, a spoon-shaped tooth (1) is cast through a casting mold, and a tooth top (2) and an antiskid strip (3) are arranged on the spoon-shaped tooth (1). Due to the fact that the antiskid strip is designed on a tooth body of the spoon-shaped tooth, the spoon-shaped tooth can be well prevented from loosing and falling in working, and accordingly the spoon-shaped tooth can be stably installed at the top of a drilling head, and service life of the spoon-shaped tooth is improved.
Description
Technical field:
The utility model relates to design Antiskid spoon shape tooth under carbide alloy above a kind of storehouse body that is arranged on rock drill.
Background technology:
The design of present scoop chisel insert, its tooth body does not all design reeding, and the tooth body of scoop chisel insert is smooth arc surface, walks because violent vibrations are prone to during operation, becomes flexible the situation that causes scoop chisel insert to occur dropping.
Summary of the invention:
Goal of the invention of the present utility model is to be prone in order to overcome scoop chisel insert the difficulty that walks, becomes flexible, and design Antiskid spoon shape tooth under a kind of carbide alloy is provided.
The utility model is to adopt following technical scheme to realize its goal of the invention: design Antiskid spoon shape tooth under a kind of carbide alloy, it casts scoop chisel insert 1 by mould, and be provided with tooth top 2 on scoop chisel insert 1, reeding 3; Tooth top 2 is located at the top of scoop chisel insert 1; Reeding 3 is located at the bottom of scoop chisel insert 1 tooth body outer ring.
Realize preferably its goal of the invention owing to having adopted above technology the utility model, reeding in the design of the tooth body of scoop chisel insert, can prevent preferably during operation that scoop chisel insert from becoming flexible, dropping, thereby make scoop chisel insert firmly be arranged on drill bit top, the application life of having improved scoop chisel insert.
Description of drawings:
Accompanying drawing 2 is section constructed profiles of the present utility model.
Accompanying drawing 3 is upper plane structure schematic diagrames of the present utility model.
Description of reference numerals is seen manual last page form.
The specific embodiment:
Below in conjunction with accompanying drawing, summary of the invention is described further:
Embodiment 1:
By accompanying drawing as can be known, design Antiskid spoon shape tooth under a kind of carbide alloy, it casts scoop chisel insert 1 by mould, and be provided with tooth top 2 on scoop chisel insert 1, reeding 3; Tooth top 2 is located at the top of scoop chisel insert 1; Reeding 3 is located at the bottom of scoop chisel insert 1 tooth body outer ring.
Lower design in denomination of invention described in the utility model " under a kind of carbide alloy design Antiskid spoon shape tooth " refers to: reeding 3 designs are in the bottom of the tooth body outer ring of scoop chisel insert 1.
