Description
Technical field
This utility model belongs to coal mining equipment technical field, is specifically related to a kind of cored screw for keeping off coal skin perforating and bores blunderbuss.
Background technology
During coal mining, it is necessary to block with Anti-fall with gear coal skin to the coal on transporter, when gear coal skin is installed, it need to be carried out perforating. Blunderbuss of existing perforating takes hammer to pound for manual, just blunderbuss is smashed unless you give your whole attention to it, perforating efficiency is very low, dangerous again, it is forced because blunderbuss is smashed when half is done in sometimes service work to stop maintenance, pounding perforating brings much inconvenience to service work by hand, and time-consuming expense material of taking a lot of work is also dangerous.
Utility model content
The purpose of this utility model is to provide a kind of cored screw for keeping off coal skin perforating and bores blunderbuss, solves the inefficient problem of perforating that existing gear coal skin perforating blunderbuss exists.
This utility model be employed technical scheme comprise that, a kind of cored screw for keeping off coal skin perforating bores blunderbuss, blunderbuss body including hollow, one end of blunderbuss body is connected with connecting rod, the other end of blunderbuss body is provided with some teeth, having groove a on blunderbuss body, the inwall of groove a is also carved with groove b; Blunderbuss body is provided with one end of teeth and is additionally provided with positioning needle; The junction of blunderbuss body and connecting rod is connected with splash guard, is provided with button cell in splash guard, and splash guard is positioned at the side of blunderbuss body and is additionally provided with some LED.
Feature of the present utility model also resides in,
Blunderbuss body is carved with latticed groove.
Positioning needle is axially arranged along blunderbuss body.
The prominent blunderbuss body of positioning needle is arranged.
The beneficial effects of the utility model are, a kind of cored screw for keeping off coal skin perforating bores blunderbuss, by recessing on blunderbuss body, it is possible to by the gear coal skin destroyed because centrifugal force screws out, it is prevented that blunderbuss blocks; By arranging teeth on blunderbuss body, it is possible to more easily cut away gear coal skin, improve perforating efficiency; By arranging positioning needle, the gear coal skin being intended to perforating can be positioned, improve perforating precision; By arranging splash guard, it is possible to prevent the gear coal skin flown away from a high speed hands of injuring from referring to; By arranging LED, this device can be made to work under the environment that light is bad. This utility model substantially increases gear coal skin perforating efficiency, has liberated labour force.
Accompanying drawing explanation
Fig. 1 is the structural representation that a kind of cored screw for keeping off coal skin perforating of this utility model bores blunderbuss.
In figure, 1. positioning needle, 2. blunderbuss body, 3. latticed groove, 4.LED lamp, 5. splash guard, 6. connecting rod, 7. teeth, 8. groove a, 9. groove b.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, this utility model is described in detail.
As shown in Figure 1, a kind of cored screw for keeping off coal skin perforating bores blunderbuss, blunderbuss body 2 including hollow, blunderbuss body 2 is carved with latticed groove 3, one end of blunderbuss body 2 is connected with connecting rod 6, the other end of blunderbuss body 2 is provided with some teeth 7, and blunderbuss body 2 has groove a8, and the inwall of groove a8 is also carved with groove b9; Blunderbuss body 2 is provided with one end of teeth 7 and is additionally provided with positioning needle 1, and positioning needle 1 is axially arranged along blunderbuss body 2, and positioning needle 1 highlights blunderbuss body 2 and arranges; The junction of blunderbuss body 2 and connecting rod 6 is connected with splash guard 5, is provided with button cell in splash guard 5, and splash guard 5 is positioned at the side of blunderbuss body 2 and is additionally provided with some LED 4.
The using method that a kind of cored screw for keeping off coal skin perforating of this utility model bores blunderbuss is: with latticed groove 3 place of the hand-held firmly blunderbuss body 2 of this device, the connecting rod 6 of this device is connected on electric drill, blunderbuss body 2 and electric drill is made to be connected firmly, then, it is directed at and is pressed in the gear coal skin being intended to punching by positioning needle 1, start electric drill, the teeth 7 of this device just start cutting gear coal skin and punch, chip by centrifugal action along with the groove a8 of blunderbuss body 2 takes out of, and flown away from by groove b9 further, splash guard 5 prevents the chip quickly flown out from stamping finger; If running into insufficient light, the LED opening this device can continue punching.
