Abstract
The invention discloses a safe and efficient anti-skid drill bit used for an air-leg rock drill. The safe and efficient anti-skid drill bit comprises a drill handle, a lower fixing rod, a drill body and a chip groove. An upper fixing rod and the lower fixing rod are mounted on the right side of the drill handle. An upper fixing nut is mounted on the upper fixing rod, and an upper anti-skid piece is mounted on the lower side of the upper fixing nut. A lower fixing nut is mounted on the lower fixing rod, and a lower anti-skid piece is mounted on the upper side of the lower fixing nut. The drill body is mounted on the left side of the drill handle. Drill wings are mounted on the drill body, and the chip groove is formed between the two drill wings. A drill tip is mounted on the left side of the drill body, and square grooves are formed in the upper side of the drill tip. According to the safe and efficient anti-skid drill bit, a certain slope is formed in the root of the drill handle so that the phenomenon that a drill rod drills into a rock mass when the drill bit is thicker than the drill rod can be quite well avoided, and the drill bit can also be quite well pulled out; push-dismounting of the drill bit can be achieved through a groove in the right side of the drill handle, a rubber blanket is mounted on the right side of the groove, and damping can be quite well achieved; and the drill bit is simple in structure and reasonable in design.
Description
Technical field
The present invention relates to drill bit apparatus technical field, specially a kind of safely and efficiently antiskid drill.
Background technology
At present, on Medium and smaller mines, because pusher leg drill has that machine heavy and light, air consumption are few, is particularly suitable for being equipped with small-sized air compressor movement operation, start flexibly, it is Pneumatic-hydraulic interlocked, efficient energy-saving, good reliability, it is easy to operate, easy-maintaining the characteristics of, therefore be still widely used on mine.In the little mine of formation hardness, such as skarns, either diabase presses down or is when probing ground buckling is than larger goaf, the normal problems faceds of drill bit Jing are bit freezings, and drilling rod is thrown into, and drill bit is thicker than drilling rod itself, drill bit is stuck by country rock and can not be pulled out out, pulling out brill by force may cause termination to come off in the borehole, in some instances it may even be possible to thus hurt people, there is very big potential safety hazard.
The content of the invention
It is an object of the invention to provide one kind safely and efficiently antiskid drill, to solve the problems, such as above-mentioned background technology in propose.
For achieving the above object, the present invention provides following technical scheme：A kind of safely and efficiently antiskid drill, including drillstock, lower fix bar, brill body and chip area；The drillstock right side is provided with fix bar and lower fix bar, and fixing nut is installed in upper fix bar, and upper fixing nut downside is provided with Anti-skid sheet, lower fixing nut is installed in the lower fix bar, and lower fixing nut upside is provided with lower Anti-skid sheet, the drillstock left side is provided with brill body, and the brill wing is installed with boring, and chip area is defined between two brill wings, the brill body left side is provided with apex point, and apex point upside is provided with square groove.
Preferably, the drillstock upside is provided with graduation apparatus.
Preferably, the root of the drillstock has certain gradient.
Preferably, triangular hill is installed inside the chip area.
Preferably, the drillstock right side is provided with groove, and groove right side is provided with rubber blanket.
Compared with prior art, the invention has the beneficial effects as follows：The present invention can be good at measuring the depth that drill bit is thrown into by the graduation apparatus that drillstock upside is arranged，Practicality is stronger，Bring great convenience for production，The root of drillstock has certain angle，Avoid in the case where drill bit is thicker than drilling rod，Drilling rod throws crag into，Cause potential safety hazard，Also can be good at realizing extracting for drill bit simultaneously，Design comparison is reasonable，The triangular hill installed by chip area inside，Can be good at realizing smashing on rock，Realize well and discharge chip，Groove can realize the convenient handling of drill bit，Improve production efficiency，The rubber blanket installed by groove right side，Can be good at mitigating vibrations，Improve comfortableness，Can be good at realizing the further fixation to drill bit by upper Anti-skid sheet and lower Anti-skid sheet，Improve security，Avoid the skidding of drill bit and drop，Practicality is stronger.
