Sidewall weld has upper hinged shaft, is equipped with mud guard on upper hinged shaft.It is limited that adapter two sidewalls are located at welding above upper mud guard
Position bar, gag lever post can limit maximum angle when mud guard is opened.
Taking trowel is second level ladder cylindrical steel tube, and tube body top inside radius is slightly larger than tube body lower part inside radius, outside tube body top
Radius is slightly smaller than tube body lower part outer radius, and tube body outer surface of upper is threaded, and bottom is designed to that the edge of a knife, the edge of a knife are
Scarf in circle.
Main body pipe shaft is process by steel pipe, and pipe shaft top two sides are cut into oblique section, and pipe shaft bottom is machined with internal screw thread,
The screw thread matches with trowel upper external thread is taken.
The working principle of the utility model is as follows:
When boring soil sampling, the drilling rod of appropriate length is selected, is connect with top adapter, sampler buries, bottom mud guard
It rotates and opens around down hinge in soil impact, soil enters main body pipe shaft, when soil sample is filled in main body pipe shaft, continues
Deeply, soil can impact top mud guard, so that it is rotated and is opened around upper hinged shaft, maximum opening is controlled by gag lever post.
When soil sampler continues deeper into, new sample goes successively to main body pipe shaft, original sample inside main body pipe shaft from
Top discharge.When having arrived designated depth, the soil sample of this depth is stored in pipe shaft.Above mention sampler, top mud guard
It is closed by soil effect above sampler, bottom mud guard is closed by main body pipe shaft inner sample gravity, needed for making
Soil sample seal up for safekeeping in main body pipe shaft, until final propose.
The utility model compared with prior art, has the advantages that
1, the utility model can be applied to weak soil sampling.In sampling, can be automatically turned on during going deep into soil
Mud guard, the soil sample inside real-time update main body pipe shaft are drawn up sample device after reaching designated depth, can be automatic
Undershield in closing enables required sample is intact to seal up for safekeeping inside main body pipe shaft.
2, the utility model compact layout, figure is small and exquisite, low in cost, easy to operate, especially suitable for ship and probing
The unapproachable Muddy Bottoms tidal zone of equipment, the original position of the shallow layer soft soils such as blast-filled ground, marshland, Hu Tang and Polluted Soil takes recently
Sample.

Specific embodiment
For a clearer understanding of the technical features, objectives and effects of the utility model, now control attached drawing is detailed
Illustrate specific embodiment of the present utility model.
As shown in Figs 1-4, the utility model provides a kind of weak soil in-situ sampler, including main body pipe shaft 6, main body pipe shaft 6
Lower part, which is equipped with, takes trowel 7, as viewed in figures 5-8, takes 7 middle part inner wall of trowel to be welded with down hinge 9, is equipped with bottom on down hinge 9
