Abstract
The utility model relates to a grind shoe, comprising a grind shoe body and a neck eye grinding body, wherein the neck eye grinding body is fixed at the bottom end of the grind shoe body, a drill pipe box is arranged at the upper part of the grind shoe body, the grind shoe body is connected with a drill stem by the drill pipe box, and the lower part of the grind shoe is in a cylinder structure. The grind shoe has a simple structure and a low cost, is convenient to use, reduces labor intensity effectively and improves working efficiency.
Description
Technical field
The utility model relates to a kind of grinding tool, particularly relates to a kind of junk mill.
Background technology
Junk mill is a kind of workover tool commonly used, is widely used because of its grinding efficiency is high.The phenomenon of fixed position grinding appears in junk mill in use easily, and after YD alloy and the whole wearing and tearing of high-abrasive material, junk will get into tool body; Make and produce friction between junk and the body; Make pump pressure the no drilling depth that rises, moment of torsion decline, thus bring a series of potential safety hazard for underground work.
Summary of the invention
The utility model has overcome deficiency of the prior art, and junk mill a kind of simple in structure, easy to use is provided.
In order to address the above problem, the utility model adopts following technical scheme:
Junk mill comprises junk mill body and neck eye mill body, and neck eye mill body is fixed on junk mill body bottom, and junk mill body top is provided with the drilling rod box, and the junk mill body links to each other with drill string through the drilling rod box, and junk mill body bottom is a cylindrical structure.
Described junk mill body bottom surface is welded with YD alloy or high-abrasive material.
Described YD alloy or high-abrasive material are provided with 4 and cross tank.
Described neck eye mill body adopts cone or cylindrical structure design.
Described neck eye mill body is provided with hydrophthalmia.
Compared with prior art, the beneficial effect of the utility model is:
The utility model is simple in structure, and cost is low, and is easy to use, effectively reduces labour intensity, improved operating efficiency.
Description of drawings
Fig. 1 is the utility model structural representation.
The specific embodiment
Junk mill, as shown in Figure 1, comprise junk mill body 1 and neck eye mill body 2, neck eye mill body 2 is fixed on junk mill body 1 bottom, and junk mill body 1 top is provided with the drilling rod box, and junk mill body 1 links to each other with drill string through the drilling rod box, and junk mill body 1 bottom is a cylindrical structure.Junk mill body 1 bottom surface is welded with YD alloy or high-abrasive material.Neck eye mill body 2 adopts cone or cylindrical structure design, plays a part the guide securement top of fish.Neck eye mill body 2 is provided with hydrophthalmia; YD alloy or high-abrasive material are provided with 4 and cross tank, and be unimpeded to guarantee circulation, effectively avoided the phenomenon of junk mill generation fixed position grinding; Thereby it is located junk by the cone or the cylinder that get in the junk; Along with the drilling tool rotation, with the junk mill grinding junk that is welded with the YD alloy, the iron filings under the grinding are taken to ground by flushing fluid then.
