The utility model proposes a kind of corning machine drill bit core ejecting device.
The technical solution of the utility model is achieved in that a kind of corning machine drill bit core ejecting device, it is characterized in that: comprise the leading screw that can be elevated, drive the screw drive mechanism of leading screw lifting, upper end is rotatably connected on the connector of leading screw lower end, and the circular steel plate be flexibly connected with connector lower end; The diameter of circular steel plate is less than the interior diameter of drill bit, and bit upper end is provided with a through hole, and the lower end of described leading screw and connector pass the through hole of bit upper end and extend into drill bit internal; Described screw drive mechanism is arranged on the top of drill bit.
As preferred technical scheme, described screw drive mechanism comprises junction plate, be arranged on leading screw drive motors on junction plate and gear train, described gear train comprises driving gear and driven gear, driving gear is connected with the output shaft of leading screw drive motors, driven gear is connected with threads of lead screw, and a side surface of driven gear and fixed head are rotationally connected.
As preferred technical scheme, described junction plate is movably connected in the top of drill bit, and described flexible connection is that bolt connects.
As preferred technical scheme, being flexibly connected of described connector and circular steel plate is external screw thread and being threaded of screw-internal thread fit, or the protruding clamping coordinated with draw-in groove.
Owing to have employed technique scheme, the utility model has following outstanding beneficial effect:
1, structure is simple, easy to use, only circular steel plate need be arranged on the lower end of connector during use, and control leading screw drive motors, circular steel plate connected piece is spacing, there will not be the generation of shifting phenomena in operation process.
2, adopt leading screw to promote circular steel plate, core is released drill bit by circular steel plate, and get core without the need to manually knocking, automaticity is high, thrust-neutral, and the dynamics of knocking when manually knocking that avoids is controlled the bad core caused and damaged, and improves the integrality that core drills through.
3, can screw drive mechanism, leading screw be taken off together with connector as required, be arranged on different drill bits and use, the scope of application is wide.

Fig. 2 is plan structure schematic diagram of the present utility model.
In figure: 1-leading screw; 2-connector; The circular steel plate of 3-; 4-drill bit; 5-junction plate; 6-leading screw drive motors.
Detailed description of the invention
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
As shown in Figure 1, 2, the utility model comprises the leading screw 1 that can be elevated, and drive the screw drive mechanism that leading screw 1 is elevated, upper end is rotatably connected on the connector 2 of leading screw 1 lower end, and the circular steel plate 3 be flexibly connected with connector 2 lower end; The diameter of circular steel plate 3 is less than the interior diameter of drill bit 4, and drill bit 4 upper end is provided with a through hole, and the lower end of described leading screw 1 and connector 2 pass the through hole of drill bit 4 upper end and extend into drill bit 4 inside.
Described screw drive mechanism is arranged on the top of drill bit 4, screw drive mechanism comprises junction plate 5, be arranged on leading screw drive motors 6 on junction plate 5 and gear train, described gear train comprises driving gear and driven gear, driving gear is connected with the output shaft of leading screw drive motors 6, driven gear is threaded with leading screw 1, one side surface and the junction plate 5 of driven gear are rotationally connected, and can realize the normal rotation of driven gear, can make again the invariant position of driven gear.Described junction plate 5 is movably connected in the top of drill bit 4, and described flexible connection is that bolt connects, and can screw drive mechanism, leading screw 1 be taken off together with connector 2 as required like this, is arranged on different drill bits 4 and uses, improve the scope of application.Leading screw drive motors 6 rotation driven gear group operates, leading screw drive motors 6 rotates to different directions and drives driven gear to rotate to different directions, leading screw 1 is made to complete lifting two actions, when needs take out core, leading screw 1 is moved downward, promotes circular steel plate 3, core is released drill bit 4 by circular steel plate 3, time saving and energy saving, easy to operate.
