The closed soil sampler of described check is characterized in: there is step in the outside, movable shoe upper end, and the outside, lower end is type conical bench.
The closed soil sampler of described check is characterized in: the check sealed tube is stainless pipe, and its sidewall has 6-10 sheet triangle check sheet, and triangle check sheet can rotate in the check sealed tube.
The closed soil sampler of described check is characterized in: triangle check sheet has bolt as the center of circle, can rotate in the check sealed tube around bolt.
The closed soil sampler of described check, be characterized in: the corresponding check sealed tube of triangle check sheet has triangle open mouth, the open outer side wall is mended with the tubing that is fit to its external diameter size and is closed, triangle check sheet is positioned at check sealed tube tube wall place, check sealed tube tube wall coincide, and is connected with the check sealed tube by pipe outside bolt.
The closed soil sampler of described check is characterized in: triangle check sheet is triangular-arc, and being connected the lower end with bolt has salient point, is check sealing front contact.
Advantage and the good effect that the utlity model has are:
The closed soil sampler of check has been owing to having adopted the brand-new technical scheme of the utility model, and compared with prior art, the utility model is as a kind of sampler locking device of taking suspended, mud scum, mucky soil.Be characterized in that the closed soil sampler of check connects successively by piston, soil sample pipe, check sealed tube, movable shoe, piston forms negative pressure of vacuum when fetching earth, the soil sample pipe is preserved soil sample, the closed soil sample that stops of check sealing activity shoe drops, and soil sample is taked up in piston and the acting in conjunction of check sealing activity shoe.
The utlity model has the advantages such as simple in structure, easy to use, dependable performance, can take that stream is moulded, the soft soil property of moulding, sampling can maintain the original state, and has improved the original state sampling effect, taking rate of mud scum, stream mud, mud, Muddy Bottoms class soil etc.

The specific embodiment
For further understanding utility model content of the present utility model, Characteristic, hereby exemplify following examples, and cooperate accompanying drawing to be described in detail as follows:
With reference to accompanying drawing 1 to Fig. 6.
The closed soil sampler of a kind of check comprises piston 1, soil sample pipe 2, check sealed tube 3 and movable shoe 4; Piston 1 connects soil sample pipe 2, check sealed tube 3, movable shoe 4 successively, piston 1, soil sample pipe 2, check sealed tube 3 threes are fixed together by screw thread, movable shoe 4 is in check sealed tube 3 inboards, be the slide type mechanical syndeton, check sealed tube 3 inboards are provided with the step that prevention activity shoe 4 comes off, there is step in the outside, movable shoe 4 upper ends, and the outside, lower end is type conical bench.Check sealed tube 3 is stainless pipe, in 8 triangle check sheets 5 that the adjustable pipe boots touch are housed; Triangle check sheet 5 has bolt as the center of circle, can be around bolt in the 3 interior rotations of check sealed tube.Triangle check sheet 5 is triangular-arc, and being connected the lower end with bolt has salient point, is check sealing front contact.Triangle check sheet 5 corresponding check sealed tubes 3 have triangle open mouth, the open outer side wall is mended with the tubing that is fit to its external diameter size and is closed, triangle check sheet 5 is positioned at check sealed tube tube wall place, coincide with check sealed tube tube wall, is connected with check sealed tube 3 by pipe outside bolt.
