Specific embodiment
With reference to the accompanying drawings and examples, specific embodiment of the present utility model is described in further detail.Below
Embodiment is used to illustrate this utility model, but is not limited to scope of the present utility model.
As Figure 1-3, it is a kind of to cross size mud cake removal device, including remover body 1, the top of the remover body 1
Portion is provided with box 2, and the bottom of remover body 1 is provided with pin thread 3, and the outer wall of remover body 1 is provided with about two and is distributed
Cutting band 4, between two cutting bands 4 buffering annular groove 5 is formed.
It is of the present utility model to cross size mud cake removal device, if remover body 1 outer wall of the cutting with 4 roots is provided with
Equally distributed radially fixed hole 6 is done, the cutting is made up of with 4 multiple steel tendons 7 being welded on inside radially fixed hole 6.
Of the present utility model to cross size mud cake removal device, described each steel tendon 7 is made up of following steel wire：4 φ 1mm, 2
Root φ 2mm and 2 φ 3mm.
Size mud cake removal device structure of crossing of the present utility model is novel, is connected with drilling rod by pin thread and box；With drilling rod
Rotate, the steel tendon on remover body outer wall is contacted with the borehole wall, for brushing off the landwaste and mud cake of the borehole wall, dredge the borehole wall, it is complete
Into the task of the cleaning borehole wall, it is connected with drilling rod, fastness is good, without foreign aid's power；Form slow between two cutting bands
Rush annular groove, cutting band bear pressure it is big when can slightly have extending space, while having buffering to big barrier and caching
Effect, is unlikely to make a mess of or block drilling rod；Remover body is provided with steel tendon fixing hole, and perforate direction is perpendicular to the center of circle, steel
Tow welding is planted in steel tendon fixing hole, firm and durable.
The above is only preferred implementation of the present utility model, it is noted that for the common skill of the art
For art personnel, on the premise of without departing from this utility model know-why, some improvement and modification can also be made, these change
Enter and also should be regarded as protection domain of the present utility model with modification.
