Specific embodiment
The utility model is described in further detail with reference to the accompanying drawing.
As shown in Figures 1 to 3, the utility model includes drill bit 1, reamer 2, basket 3, reacting cycle pipe 4 and drilling rod 6, institute
It states that drill bit 1, reamer 2, basket 3, reacting cycle pipe 4 and drilling rod 6 are sequentially connected and inside communicates, is set in the reacting cycle pipe 4
There is reacting cycle partition 401, and is equipped with the first water outlet on 4 tube wall of reacting cycle pipe between the reacting cycle partition 401 and drilling rod 6
Hole 402 is equipped with the second apopore 403 on 4 tube wall of reacting cycle pipe between the reacting cycle partition 401 and basket 3, in institute
It states and is equipped with ring for the sealing liquid 5 outside reacting cycle pipe 4, and the ring for the sealing liquid 5 is set to first apopore 402 and the second apopore 403
Between, 5 edge of ring for the sealing liquid is close to, in order to guarantee water sealing effect, be equipped with two in the present embodiment to prevent water from flowing back with rock stratum
Road ring for the sealing liquid 5.
As shown in Fig. 2, the reacting cycle pipe 4 includes the first pipeline section 404 and the second pipeline section 405,404 He of the first pipeline section
Second pipeline section 405 is weldingly connected, and 401 section of reacting cycle partition is Z-shape, and the reacting cycle partition 401 includes first partition
Section 4011, intermediate bulkhead section 4012 and second partition section 4013, wherein 4011 semicircular in shape of first partition section and along radial weldering
It is connected in the first pipeline section 404,4013 semicircular in shape of second partition section and is welded in the second pipeline section 405 along radial, middle interval
The upper down space of isolation reacting cycle pipe 4 is axially arranged in plate section 4012, and 4012 both ends of intermediate bulkhead section are respectively with first
Separator segment 4011 is connected with second partition section 4013.The first partition section 4011 of reacting cycle partition 401 first protrudes into first when processing
Welding is connected in pipeline section 404, and second partition section 4013 protrudes into welding in the second pipeline section 405 again and is connected, then again by the first pipeline section
404 and second pipeline section 405 welding be connected, be effectively ensured the reacting cycle partition 401 will not occur leakage influence water circulation.
As shown in Fig. 2, being equipped with filter screen 406 in the first pipeline section 404 being connected with basket 3 for filtering as water flow is moved
Dynamic fine particle 7 is stranded between 4 tube wall of reacting cycle partition 401 and reacting cycle pipe after avoiding particle 7 from entering reacting cycle pipe 4
Blocking the second apopore 403 influences return water.

The working principle of the utility model are as follows:
As shown in figure 4, water is successively flowed along drilling rod 6 and basket 3 on water pump in the prior art, finally flowed by drill bit 1
Out, and water flows out backward two sides reverse flow, the limbers on reamer 2 is first passed through, then along the sky between tube wall and rock stratum
Gap realizes return water, since water direction upper in basket 3 offsets with 7 moving direction of particle, easily causes basket 3 to block and influences rock
The heart or mine heart extraction efficiency, also will increase resistance reduces probing penetration rate.
The utility model as shown in Figure 1, on water pump water first along drilling rod 6 flow, into reacting cycle pipe 4 after due to reacting cycle
The blocking of partition 401 is flowed out by the first apopore 402, and flows to drill bit 1 along the gap between tube wall and rock stratum, at this time ring for the sealing liquid
5 prevent the effluent recycling of the first apopore 402, and water flow to after drill bit 1 and reversely flows into drill bit 1, and enters in basket 3,
Since water (flow) direction is identical with 7 moving direction of particle, the blocking of basket 3 not will cause, improve rock core or mine heart recovery rate, and
Also resistance is effectively reduced, improves probing penetration rate, and since drill bit 1 is rotary operation, will not influence the cooling etc. of water
Effect, the water in basket 3 enter after reacting cycle pipe 4 since the reacting cycle partition 401 stops to be flowed by the second apopore 403
Out, and along the interstitial flow return water between tube wall and rock stratum, ring for the sealing liquid 5 prevents the effluent recycling of the second apopore 403 at this time.
