Abstract
Disclosed is a winding drill stem. Spiral fins are wound on the periphery of a drill stem body, a drill handle hole is arranged at the front end of the drill stem body, a clamping bead fixing hole is radially arranged in the drill handle hole, a drill handle is fixed at the rear end of the drill stem body, a clamping bead is disposed on the drill handle, and the drill handle is communicated with the drill stem body via a water channel. The drill handle is a square drill handle, and the drill handle hole is an inner square hole corresponding to the drill handle. The winding drill stem can conveniently lead cooling water to a drill bit, so that power consumption is reduced, and the service life of a drill is prolonged.
Description
Technical field
The utility model relates to a kind of winding drilling rod, is used for the mixed coal electric drill and plays the use of coal hole.
Background technology
Coal Production adopts the winding rod boring of no-cooling-water passage at present, causes supporting with it drill bit very easily to be burnt, and influences the application life of drilling tool, can not meet the needs of production.
Summary of the invention
The purpose of this utility model provides a kind of winding drilling rod, solves that original winding drilling rod can not lead to cooling water in use and the defective of burning of bits head easily.
The purpose of this utility model realizes as follows: the periphery of drilling rod body is wound with the spiral wing, and the front end of drilling rod body has the drillstock hole, and the drillstock aperture is to card beans fixing hole is arranged; The rear end of drilling rod body is drillstock fixedly, and drillstock is provided with the card beans, and drillstock and drilling rod body have the water channel that communicates.Can give drill bit water flowing cooling by water channel, auxiliary chip removal.
Drillstock is cubic drillstock, and the drillstock hole is the internal square hole of corresponding drillstock.Drillstock and drillstock hole are tetragonal, and transfer torque is big, good reliability.
The utility model can reduce power consumption conveniently to the logical cooling water of drill bit, prolongs the application life of drilling tool.
Description of drawings
Accompanying drawing is a structural representation of the present utility model.
The specific embodiment
With reference to accompanying drawing, the periphery of drilling rod body 4 is wound with spiral wing 5, and the front end of drilling rod body 4 has drillstock hole 7, and drillstock hole 7 inner radial have card beans fixing hole 6; The rear end of drilling rod body 4 is drillstock 3 fixedly, and drillstock 3 is provided with card beans 1, and drillstock 3 and drilling rod body 4 have the water channel 2 that communicates.Drillstock 3 is cubic drillstock, and drillstock hole 7 is the internal square hole of corresponding drillstock 3.
