Specific embodiment

In the following, being described further in conjunction with attached drawing and specific embodiment to the utility model, it should be noted that Under the premise of not colliding, it can be formed in any combination between various embodiments described below or between each technical characteristic new Embodiment.

The hand power screw sampler of one preferred embodiment of the utility model, including probe tube 1 are shown referring to Fig. 1, is sampled Pipe 1 has lumen 11, and lumen 11 can accommodate sample, and probe tube 1 offers feed inlet 12, discharge port 13；Feed inlet 12 is used for Enter lumen 11 for sample, discharge port 13 is used to flow out for the sample collected in lumen 11；Hand power screw sampler further includes spiral shell Spin axis 2, probe tube 1 are also provided with waste outlet 14；Waste outlet 14 is used to be discharged for remaining sample, 2 insertion pipe of helical axis Chamber 11, when helical axis 2 is rotated in a first direction, the sample in lumen 11 can be delivered to by helical axis 2 from feed inlet 12 At discharge port 13；When helical axis 2 is rotated in a second direction, helical axis 2 can be by sample remaining in lumen 11 from lumen 11 It inside drains at waste outlet 14；First direction is opposite with second direction.Wherein, first direction can be clockwise direction or inverse time Needle direction, and second direction is then correspondingly for counterclockwise or clockwise.When work, by rotating helical axis manually 2, to the stale sample remained in lumen 11 is discharged from waste outlet 14, to avoid stale sample interference inspection It surveys as a result, to improve the accuracy of testing result；Probe tube 1 is equipped with to one end insertion sample sack or sample of feed inlet 12 again In product library, helical axis 2 is then rotated, it can be by fresh sample collection to lumen 11, and by the blade of helical axis 2 promotion sample Product along lumen 11 axial advancement, to be transmitted to discharge port 13.

Preferably, waste outlet 14 is set to the top of the first end of probe tube 1, and feed inlet 12 and discharge port 13, which are set to, to be taken The side wall of sample pipe 1, feed inlet 12 are provided close at the position of the first end of probe tube 1, and discharge port 13 is provided close to probe tube 1 At the position of second end.Also, in this embodiment, it is preferred that the axis of waste outlet 14, the axis of helical axis 2 and sampling The axis three of pipe 1 is conllinear.By the way that waste outlet 14 to be set to the top of the first end of probe tube 1, so that helical axis 2 rotates When, the stale sample of remaining can be pushed along the axis of probe tube 1 by the thrust of blade, and straight from waste outlet 14 Run in out, the better effect of stale sample is discharged.Moreover, because the probe tube 1 of this hand power screw sampler is general when working It is horizontal positioned, by the way that feed inlet 12 and discharge port 13 to be set to the side wall of probe tube 1, so that sample more easily enters lumen 11 Or flowed out from lumen 11, it is more preferable using effect.Also, the position by the first end that feed inlet 12 is provided close to probe tube 1 Place, discharge port 13 is provided close at the position of the second end of probe tube 1, so that feed inlet 12 has enough apart from discharge port 13 Distance, consequently facilitating probe tube 1 be inserted into sufficient length to sample sack or sample library in.

Referring to Fig. 1, further, feed inlet 12 and discharge port 13 are arranged along the circumferential misalignment of probe tube 1, and feed inlet 12 Extending direction it is parallel with the extending direction of discharge port 13.Therefore, when the direction of feed inlet 12 upward when, the direction of discharge port 13 Then downward, so that more conducively sample is by self gravity and along feed inlet 12 into lumen 11, while being also conducive to sample by itself weight Power along discharge port 13 outflow, consequently facilitating sample collection is got up.

Preferably, the second end of probe tube 1 offers support port 15, the socket of helical axis 2 supports port 15, and by supporting Port 15 supports.Further, support port 15 is equipped with bearing 16, and the inner ring of bearing 16 is connect with helical axis 2, bearing 16 Outer ring is connect with support port 15.So that the rotation of helical axis 2 is more stable and laborsaving, and it is not easy to locate failure, and be easy Maintenance.

Preferably, support port 15 is connected with sealing cover 17, sealing cover 17 is for preventing sample along the second end of probe tube 1 Leakage reduces environmental pollution so that sample be avoided to trickle down external environment.

Preferably, the second end of helical axis 2 is connected with handle 18, handle 18 is for rotating helical axis 2.Consequently facilitating manpower Crawl handle 18 simultaneously rotates helical axis 2.

Preferably, discharge port 13 is formed with discharge nozzle 131 along the radially extending for side wall of probe tube 1.Pass through discharge nozzle 131 Guidance, it is unrestrained when can be flowed out to avoid sample from lumen 11 and pollute environment.Further, sampler further includes manual ball valve 19, manual ball valve 19 is connect with discharge nozzle 131, and is opened or closed for controlling discharge nozzle 131.Pass through setting for manual ball valve 19 It sets, so that the sample of discharge port 13 can be controlled in an orderly manner, it can convenient for taking sample by several times, and will not lead Sample is caused to spill to external environment, it is contaminated so as to avoid environment.Further, the side wall of sampler is also welded with flange 3, flange 3 is for connecting sampling bag or sampling library etc., to avoid manually holding this hand power screw sampler for a long time.

The hand power screw sampler of the utility model has benefit below:

1, the rotation of helical axis 2 can be driven, consequently facilitating sample is delivered to out from feed inlet 12 in manual swing handle 18 Material mouth 13, and pass through the control of the progress discharge port 13 of manual ball valve 19.

2, before and after each use, can manual swing handle 18, and by the stale sample remained in lumen 11 along useless 14 discharge of material outlet.

3, sample is pushed due to helical axis 2 using blade, and helical axis 2 will not be moved axially, because without Phenomena such as suck-back, flash can occur.

4, the safety of this hand power screw sampler is good, and environmental pollution is small, compact-sized, and failure is few, while being also convenient for tieing up Shield.

Above embodiment is only preferred embodiments of the present invention, cannot be protected with this to limit the utility model Range, the variation of any unsubstantiality that those skilled in the art is done on the basis of the utility model and replacement belong to In the utility model range claimed.
