Existing drilling operation, but easily aggravate the abrasion of auger line because of heating in processing, and easily snap off drilling rod, so
Applicability and practicality are restricted.
Content of the invention
In order to solve above-mentioned technical problem, the purpose of this utility model is to provide that a kind of stability in use is good, easy disassembly
And can effectively ensure that the drilling tool with cross cutter head of drilling efficiency.
The technical scheme realizing the utility model purpose is a kind of drilling tool with cross cutter head, including drilling rod, arranges
In swivelling chute and the connection screens portion being arranged on described drilling rod rear end of described drilling rod front end, it is additionally provided with cross cutter head, in institute
The front end stating drilling rod is provided with cross draw-in groove, is provided with arc and fixes shell fragment, in described brill on the inwall of described cross draw-in groove
It is provided with cooling liquid passage in bar, the nozzle being connected with described cooling liquid passage is provided with the inwall of described cross draw-in groove,
The side of described cross cutter head is provided with intake chute.
It is provided with arc and strengthens even muscle between the adjacent side of described cross cutter head, described cross cutter head screens is in institute
When stating in cross draw-in groove, the front end of described drilling rod is pressed on described arc reinforcement and connects on the end face of muscle.
It is the 1/2 of cross blade cephalic pleurite height that described arc strengthens even muscle height.
Described arc is strengthened even muscle and is wholely set with described cross blade head, and described intake chute passes through described arc to strengthen
Even muscle setting.
The utility model has positive effect：Structure of the present utility model is simple, simple operation, can tear open as needed
Dress cross cutter head, thus effectively drill pipe wear can be prevented, and is provided with cooling liquid passage and nozzle, can be timely and effectively right
Cross cutter head carries out hydrojet cooling, such that it is able to reduce the abrasion of cross cutter head, extends making of cutter head to a certain extent
With the life-span, stability in use is good, strong applicability and practicality is good.
