Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention will be further described in detail.
The advanced telescopic Sampling driller of the present invention comprises outer barrel assembly (Fig. 4) and sampler assembly (Fig. 3).
As shown in Figure 1, sampler assembly of the present invention comprises: spearhead 8, bullet card recovery tube 9, bullet card 10, hanging ring 11, return connector 12, upper dental inlay clutch 13, spring 14, lower dental inlay clutch 15, axle 16, steel ball 17, liner adapter 18, inner core joint 19, inner core 20, bushing pipe 21, pull spring 22, clip 23 and pilot bit 24.Wherein spearhead 8, bullet card recovery tube 9, hanging ring 11, return connector 12 set gradually in order, and bullet card 10 is arranged in bullet card recovery tube 9, composition salvaging mechanism.The two ends of axle 16 extend in dental inlay clutch 13, lower dental inlay clutch 15 respectively, and on axle 16, be provided with spring 14, upper dental inlay clutch 13, lower dental inlay clutch 15, axle 16 and spring 14 constitute dental inlay clutch, spring 14 can automatically extend according to different stresses or shrink, and namely dental inlay clutch can unclamp automatically or engage.Steel ball 17, liner adapter 18, inner core joint 19, inner core 20, pull spring 22, clip 23, pilot bit 24 set gradually in order, bushing pipe 21 is placed in inner core 20, composition sampling mechanism.Salvaging mechanism, dental inlay clutch and sampling mechanism are integrated by thread connection successively.
