Description
Technical field:
The utility model belongs to technique with the apparatus field, colliery, is specifically related to a kind of New Coal Mine target drill.
Background technology:
In long-term working practice, staff is in the drill bit process changing same model damage, whole drill bit must disassemble and change by staff, and exchonge step is many and loaded down with trivial details in Renewal process, reduce staff's operating efficiency, inconvenient staff uses and increases the workload of staff.
Utility model content:
The purpose of this utility model is: in order to solve staff in the drill bit process changing same model damage, staff is without the need to disassembling i.e. interchangeable bit by whole drill bit, and the bit change-over that can will damage fast, facilitate staff to use and increase work efficiency, its technical scheme is as follows:
A kind of New Coal Mine target drill, it comprises fixed leg 1, fixing card column 2, drill body 3, retainer ring 4, external screw thread 5, fixing chute 6, drill bit cutter head 7, it is characterized in that: on described fixed leg 1, top end surface circle centre position is fixedly connected with fixing card column 2, in described fixing card column 2, top end surface circle centre position is fixedly connected with drill body 3, described drill body 3 side surface is fitted with retainer ring 4, above described drill body 3 side surface surrounding, 1/3rd places are provided with external screw thread 5, top end surface top edges surrounding place, described drill body 3 side average mark is furnished with several fixing chutes 6, each described fixing chute 6 inside is fixedly fitted with drill tip 7, described fixing card column 2 external diameter is greater than described drill body 3 external diameter, and described fixing card column 2 external diameter size is identical with described retainer ring 4 external diameter size, described drill body 3 external diameter size is identical with described retainer ring 4 interior diameter size, and described retainer ring 4 inner lateral surfaces lower edge place is provided with internal thread, the T-shaped shape of described fixing chute 6, described drill tip 7 times T-shaped shapes of top end surface, and described drill tip 7 times T-shaped shape sizes of top end surface are identical with fixing chute 6 size, described retainer ring 4 height is 1/3rd height of described drill body 3.
The beneficial effects of the utility model are: in order to solve staff in the drill bit process changing same model damage, staff is without the need to disassembling i.e. interchangeable bit by whole drill bit, and the bit change-over that can will damage fast, facilitates staff to use and increases work efficiency.
Accompanying drawing illustrates:
Fig. 1 is overall structure schematic diagram of the present utility model.
Detailed description of the invention:
With reference to a kind of New Coal Mine target drill described in Fig. 1, it comprises fixed leg 1, fixing card column 2, drill body 3, retainer ring 4, external screw thread 5, fixing chute 6, drill bit cutter head 7, it is characterized in that: on described fixed leg 1, top end surface circle centre position is fixedly connected with fixing card column 2, in described fixing card column 2, top end surface circle centre position is fixedly connected with drill body 3, described drill body 3 side surface is fitted with retainer ring 4, above described drill body 3 side surface surrounding, 1/3rd places are provided with external screw thread 5, top end surface top edges surrounding place, described drill body 3 side average mark is furnished with several fixing chutes 6, each described fixing chute 6 inside is fixedly fitted with drill tip 7, described fixing card column 2 external diameter is greater than described drill body 3 external diameter, and described fixing card column 2 external diameter size is identical with described retainer ring 4 external diameter size, described drill body 3 external diameter size is identical with described retainer ring 4 interior diameter size, and described retainer ring 4 inner lateral surfaces lower edge place is provided with internal thread, the T-shaped shape of described fixing chute 6, described drill tip 7 times T-shaped shapes of top end surface, and described drill tip 7 times T-shaped shape sizes of top end surface are identical with fixing chute 6 size, described retainer ring 4 height is 1/3rd height of described drill body 3.
During use, first fixed leg 1 is inserted in rig also fixing, then inserted by drill tip 7 in the fixing chute 6 on drill body 3, then will retainer ring 4 move on the external screw thread 5 that is simultaneously screwed into by the internal thread of retainer ring 4 inside on drill body 3, finally starting rig can use.
Certainly; above-mentioned explanation is not to restriction of the present utility model; the utility model is also not limited in above-mentioned citing, the change that those skilled in the art make in essential scope of the present utility model, remodeling, interpolation or replacement, also should belong to protection domain of the present utility model.
