Abstract
The utility model relates to technical field of mechanical equipment, and be specifically related to a kind of eccentric drill head, it is characterized in that, drill head adopts eccentric yi word pattern, and one side is for facing directly, and one side is inclined-plane.The utility model structure is simply easy to use, and adopt eccentric structure, face lower cutter directly, side, inclined-plane is split, and result of use is better, has Social benefit and economic benefit very widely.
Description
Technical field
The utility model relates to technical field of mechanical equipment, is specifically related to a kind of eccentric drill head.
Background technology
Well lane engineering uses drill steel to be connect drill bit and rock drilling equipment, the drill steel that mine tunnel engineering generally uses is hexagonal cored steel and hollow round steel, common drill steel head is yi word pattern, during actual use, first cut a hole a hole mostly, then to surrounding's expansion in hole, in fact when drill steel major part practicality be an inclined-plane of yi word pattern.
Summary of the invention
When the utility model is for adapting to actual use, a word drill head is cut a hole under being actually a face, the service condition that a face is tiltedly split, and proposes a kind of eccentric drill head.
The technical solution adopted in the utility model is: a kind of eccentric drill head, is characterized in that, drill head adopts eccentric yi word pattern, and one side is for facing directly, and one side is inclined-plane.
The beneficial effects of the utility model are: the utility model structure is simply easy to use, and adopt eccentric structure, face lower cutter directly, side, inclined-plane is split, and result of use is better, has Social benefit and economic benefit very widely.
Accompanying drawing explanation
Fig. 1 front view of the present utility model;
Fig. 2 left view of the present utility model.
Reference numeral: 1-drill head, 2-face directly, 3-inclined-plane.
Detailed description of the invention
Be further described the utility model below in conjunction with accompanying drawing, a kind of eccentric drill head, is characterized in that as depicted in figs. 1 and 2, and drill head 1 adopts eccentric yi word pattern, and one side is for facing 2 directly, and one side is inclined-plane 3.
Above embodiment is only unrestricted for illustration of the technical solution of the utility model, and be that the utility model has been described in detail with reference to embodiment, those of ordinary skill in the art is to be understood that.May modify to the technical solution of the utility model or equivalent replacement, and not depart from the spirit and scope of technical solutions of the utility model.Under the prerequisite of spirit and scope not departing from technical solutions of the utility model, the utility model also has various changes and modifications, and these changes and improvements are all in claimed scope.
