Utility model content
The purpose of this utility model is for the problems referred to above, provides a kind of guide strip of no-dig technique orientation drill, poor with the guide strip abrasion resistance properties solving existing no-dig technique orientation drill, application life is short, guiding, boring poor performance problem.
The purpose of this utility model is achieved through the following technical solutions:
A kind of guide strip of no-dig technique orientation drill, comprise the plate body be made up of Steel material, one end of described plate body offers multiple counterbore matched with the screw on orientation drill inclined-plane, its other end is by the first end face be arranged symmetrically with, second end face cooperation is formed with guide digging cone angle, described first end face, angle between second end face with plate body Central Symmetry face is identical, it is 70 ° ~ 80 °, on the both sides end face that described plate body is formed with guide digging cone angle one end and the first end face, second end face is provided with multiple hard alloy head for strengthening pilot hole performance, and the edge built-up welding of plate body end face has the welding bead of abrasion resistance properties, described welding bead surface welding-on has the tungsten carbide particle of high rigidity performance.
As preferred version of the present utility model, described counterbore is provided with 2 rows, and 2 described row's counterbores are arranged in parallel, and often arrange and are equidistantly evenly equipped with 3 counterbores.
As preferred version of the present utility model, described first end face, angle between the second end face and plate body Central Symmetry face are 75 °, adopt the guide digging cone angle that this angular compliance is formed, and steering capability is optimum.
As preferred version of the present utility model, described first end face is evenly equipped with 3 hard alloy heads, described second end face is evenly equipped with 3 hard alloy heads, the both sides end face that described plate body is formed with guide digging cone angle one end is provided with 3 equally distributed hard alloy heads.
As preferred version of the present utility model, the termination of described hard alloy head is provided with the guide head play the guiding role of truncated cone-shaped structure.
The beneficial effects of the utility model are, the guide board structure of described no-dig technique orientation drill is simple, be easy to realize, by arranging guide digging cone angle, hard alloy head, effectively improve pilot hole performance, and passing through bead welding, and at the tungsten carbide particle of welding bead surface welding-on high rigidity, effectively improve abrasion resistance properties, avoid the hard alloy head that invar making sheet body rapid wear causes and come off, extend application life.

Detailed description of the invention
The technical solution of the utility model is further illustrated by detailed description of the invention below in conjunction with accompanying drawing.Be understandable that, embodiment described herein only for explaining the utility model, but not to restriction of the present utility model.
Please refer to shown in Fig. 1 and Fig. 2, Fig. 1 is the front view of the guide strip of a kind of no-dig technique orientation drill of the utility model; Fig. 2 is the top view of the guide strip of a kind of no-dig technique orientation drill of the utility model.
In the present embodiment, a kind of guide strip of no-dig technique orientation drill, comprise the plate body 1 be made up of Steel material, the counterbore 2 that the screw that the left end of described plate body 1 is arranged with 2 rows and orientation drill inclined-plane in parallel matches, often arrange and be equidistantly evenly equipped with 3 counterbores 2, its right-hand member is by the first end face 3 be arranged symmetrically with, second end face 4 cooperation is formed with guide digging cone angle 8, described first end face 3, angle between second end face 4 with plate body 1 Central Symmetry face is identical, it is 75 °, and the first end face 3 is evenly equipped with 3 hard alloy heads 5, second end face 4 is evenly equipped with 3 hard alloy heads 5, the both sides end face of described plate body 1 right-hand member is provided with 3 equally distributed hard alloy heads 5, the termination of described hard alloy head 5 is provided with the guide head 6 play the guiding role of truncated cone-shaped structure, and the edge built-up welding that plate body 1 eats native end face has the welding bead 7 of abrasion resistance properties, the surperficial welding-on of described welding bead 7 has the tungsten carbide particle of high rigidity performance.
