As a preferred technical solution of the present invention, the second helical blade side, the second rhombus blade side and
The apex point blade side is provided with alloy head.
As a preferred technical solution of the present invention, the grout outlet is between first block and second block.
As a preferred technical solution of the present invention, first Cylindrical Blade and second Cylindrical Blade are through described
Drill body.
The beneficial effect that is reached of the present invention is：Drill body side is provided with the first Cylindrical Blade, and the first Cylindrical Blade can root
Select to add according to needs or be not added with alloy head, operation is very flexible；And first Cylindrical Blade side be provided with the first helical-blade
Piece, by increasing capacitance it is possible to increase mixing effect；Second Cylindrical Blade side is provided with the first block, and the first block side is provided with grout outlet,
And grout outlet opposite side is provided with the second block, i.e., grout outlet is between the first block and the second block so that does not crush also
The magma not being ejected on rock makes fuzzy, and the magma for avoiding ejection makes fuzzy periphery rock and influences to operate, and protects
Stable operating efficiency is demonstrate,proved；Second helical blade side, the second rhombus blade side and apex point blade side are provided with conjunction
Golden head so that crushed rock is more quick, so as to improve operating efficiency.

Embodiment
The preferred embodiments of the present invention are illustrated below in conjunction with accompanying drawing, it will be appreciated that preferred embodiment described herein is only
For instruction and explanation of the present invention, it is not intended to limit the present invention.
Embodiment：As shown in Figure 1-2, the present invention provides one kind and opens rock drill bit, including drill body 1, the side of drill body 1
The first Cylindrical Blade 8 is provided with, and the side of the first Cylindrical Blade 8 is provided with the first helical blade 2；First helical blade 2 one
Side is provided with the first rhombus blade 3, and the side of the first rhombus blade 3 is provided with the second Cylindrical Blade 10；Second Cylindrical Blade 10
