In order to achieve the above object, the utility model provides a following technical scheme:
the cone welding mechanism comprises a cone leg, wherein one end of the cone leg is rotatably connected with a cone head, the outer wall of the cone head is fixedly connected with gear teeth, and a slope is arranged on the side edge of the cone leg.
Optionally, the gear teeth are fixedly connected to the outer wall of the cone head, and the gear teeth are arranged on the outer wall of the cone head in an annular array.
Optionally, the gear teeth are made of alloy, and the gear teeth are conical.
Optionally, a connection port adapted to one end of the bit leg is disposed at one end of the cone head.
Optionally, the outer wall of the cone head is provided with a plurality of tooth holes, and one end of each tooth is matched with the tooth hole on the outer wall of the cone head.
Compared with the prior art, the utility model provides a gear wheel welding mechanism possesses following beneficial effect:
the utility model discloses a set up domaticly in the bit leg side, when the welding, welding area improves the welding fastness greatly, convenient welding to welded installation effectiveness has been improved.
Drawings

Fig. 1 is a front view of the present invention;
fig. 2 is a side view of the present invention;
fig. 3 is a top view of the present invention.
In the figure: 1. a bit leg; 2. a cone head; 3. gear teeth; 4. a slope surface.
Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
In the description of the present invention, it should be noted that the terms "vertical", "upper", "lower", "horizontal", and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for convenience of description and simplification of the description, but do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus, should not be construed as limiting the present invention.
In the description of the present invention, it should be further noted that, unless explicitly stated or limited otherwise, the terms "disposed," "mounted," "connected," and "connected" are to be construed broadly and may be, for example, fixedly connected, detachably connected, or integrally connected, mechanically connected, electrically connected, directly connected, connected through an intermediate medium, or connected to the inside of two elements. The specific meaning of the above terms in the present invention can be understood according to specific situations by those skilled in the art.
Referring to fig. 1-3, in this embodiment: the cone welding mechanism comprises a cone leg 1, wherein one end of the cone leg 1 is rotatably connected with a cone head 2, the outer wall of the cone head 2 is fixedly connected with gear teeth 3, the side edge of the cone leg 1 is provided with a slope 4, the gear teeth 3 are fixedly connected to the outer wall of the cone head 2, the gear teeth 3 are arranged on the outer wall of the cone head 2 in an annular array manner, the gear teeth 3 are made of alloy, and the gear teeth 3 are conical; the bit leg 1 is used for welding with the drilling tool each other, set up the cone head 2 and be used for the well drilling with the teeth of a cogwheel 3, can deal with various topography when the construction, be connected between bit leg 1 and the cone head 2 and be provided with certain inclination, inclination should not too big or undersize, the inclination undersize, cutting edge part is too fragile, will cause the cutting edge fracture like this, simultaneously, cutting inclination still can influence the curl degree of cutting, if the inclination is bigger, the cutting can tightly curl into the spiral, the inclination can be fixed into certain angle according to the work piece needs under the normal condition, this angle value is that does not recommend the self-change.
One end of the cone head 2 is provided with a connecting port matched with one end of the bit leg 1; the connection port is used for fixing the cone head 2 at one side of the bit leg 1.
The outer wall of the gear head 2 is provided with a plurality of tooth holes, and one end of the gear teeth 3 is matched with the tooth holes on the outer wall of the gear head 2; the gear head 2 is provided with a tooth hole, and the tooth hole is used for installing the gear teeth 3.
The utility model discloses a theory of operation and use flow: during the welding with the weld groove that 1 embedding drilling tool of bit leg set up, then weld along domatic 4 edges and weld groove edge during the welding, because domatic 4 has certain angle, its edge and weld groove edge parallel and level, it is easier during the welding, the face of weld connects the increase, and more welding materials can be piled up to the junction, and the welding is more firm to the easy adhesion of welding makes things convenient for the welding material, has improved welding efficiency.
The above only is the preferred embodiment of the present invention, not so limiting the patent scope of the present invention, all under the concept of the present invention, the equivalent structure transformation made by the contents of the specification and the drawings is utilized, or the direct/indirect application is included in other related technical fields in the patent protection scope of the present invention.
