The specific embodiment
Below in conjunction with accompanying drawing the present invention is done further detailed explanation.
The leading 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 tooth embedding clutch 13, spring 14, lower tooth embedding 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 the bullet card recovery tube 9 the composition salvaging mechanism.The two ends of axle 16 extend into respectively in upper tooth embedding clutch 13, the lower tooth embedding clutch 15; And axle 16 is provided with spring 14; Upper tooth embedding clutch 13, lower tooth embedding clutch 15, axle 16 and spring 14 have been formed tooth embedding clutch; Spring 14 can be according to elongation or the contraction automatically of different stresses, and tooth embedding clutch promptly can be unclamped or mesh automatically.Steel ball 17, liner adapter 18, inner core joint 19, inner core 20, pull spring 22, clip 23, pilot bit 24 and set gradually in order, bushing pipe 21 places in the inner core 20, forms sampling mechanism.Salvaging mechanism, tooth embedding clutch and sampling mechanism are one through thread connection successively.
