Abstract
The utility model relates to a screw-in type soil sample preparation tool. An outer screw thread layer is arranged at the tail end of the soil sample preparation tool, a tail cover is added to the soil sample preparation tool, is provided with an internal screw thread and can be sheathed and screwed at the tail of the soil sample preparation tool, a rotating shaft is fixed at the center of the tail cover of the soil sample preparation tool, one hole penetrating through the rotating shaft is formed in the rotating shaft, one metal bar with the length more than the diameter of the tail cover of the soil sample preparation tool can penetrate through the rotating shaft through the hole, and the soil sample preparation tool can be conveniently driven to rotate by rotating the metal bar. When the soil sample preparation tool operates, the end face of a knife edge is in the shape of an inverted triangle, a knife point is downward, the projection width of a knife tail in the vertical direction is more than the thickness of the wall of the soil sample preparation tool, the upper side of the triangle of the end face of the knife edge inclines downward from inside to outside at a contact part with the wall of the soil sample preparation tool, holes are uniformly distributed along a horizontal line, on the contact part of the wall of the soil sample preparation tool, of the upper side of the triangle of the end face of the knife edge, and the holes penetrate through the wall of the soil sample preparation tool, so that the knife edge can enter a soil sample to sample soil more easily.
Description
Technical field
The utility model relates to civil engineering sampling instrument field, relates in particular to a kind of preparation of soil sample instrument.
Background technology
Preparation of soil sample instrument is a kind of testing equipment for soil test, is mainly used to produce soil sample, is used for measuring tests such as native density, water cut.Preparation of soil sample instrument comes down to a column type sleeve rigidity, both ends open, and wherein an end has sharper cutting edge.When concrete the use, prepare bigger soil body sample earlier, then preparation of soil sample instrument is placed on the soil sample, cutting edge contacts with specimen surface, firmly to pressing down, makes preparation of soil sample instrument enter soil sample then.In the process that preparation of soil sample instrument is moved downward, in the soil sample of the blade of preparation of soil sample instrument incision periphery, after preparation of soil sample instrument enters fully and penetrates the soil sample layer, the soil sample in the preparation of soil sample instrument taken out just made complete soil sample.In traditional experiment, be that the mode of directly pressing is by hand compressed into soil sample downwards with preparation of soil sample instrument, yet if run into the hard sample of soil property, the edge of a knife is not easy incision, simplified manual is pressed into difficulty especially.Therefore, must be pressed into the soil sample mode and the edge of a knife improves to preparation of soil sample instrument, can reach to be pressed into easily in the certain degree of hardness sample.
Summary of the invention
In hard soil property, materials for convenience, the utility model proposes a kind of screw-in preparation of soil sample instrument, the preparation of soil sample instrument tail end that fetches earth has an external thread layer, and increase a tail-hood, tail-hood has internal thread tail-hood can be enclosed within preparation of soil sample instrument afterbody and screws, the tail-hood center fixation has rotating shaft, a hole that penetrates rotating shaft is arranged in the rotating shaft, can the Metallic rod that a length surpasses preparation of soil sample instrument tail-hood diameter be through in the rotating shaft by this hole, by the rotating metallic bar, can drive preparation of soil sample instrument easily and rotate, preparation of soil sample instrument is successfully entered in the hard soil sample.
Further improvement of the utility model, edge of a knife end face is del during preparation of soil sample tool work, point of a knife is downward, the cutter tail in the projection width of vertical direction greater than preparation of soil sample tool wall thickness, the triangle top of edge of a knife end face is downward-sloping from inside to outside in the contact position of preparation of soil sample tool wall, the horizontal line of triangle top in the contact position of preparation of soil sample tool wall of edge of a knife end face is evenly distributed with hole, hole penetrates preparation of soil sample tool wall, the incision soil sample is produced soil sample easily, soil sample is difficult for blocking, and avoids causing the phenomenon that is difficult for taking-up.
The utility model has been obtained following technique effect:
By the utility model preparation of soil sample instrument is improved, mode is pressed in available common craft, can smoothly preparation of soil sample instrument be pressed in the hard soil sample to materials.Whole sampling process uniform force application has improved efficient and the quality of sampling.
Description of drawings
Fig. 1 is screw-in preparation of soil sample instrument synoptic diagram of the present utility model.
Embodiment
Understand and enforcement the utility model for the ease of those of ordinary skills, below in conjunction with the drawings and the specific embodiments the utility model is described in further detail.
Embodiment 1:
See Fig. 1, a kind of screw-in preparation of soil sample of the utility model instrument comprises preparation of soil sample instrument 1 and the edge of a knife 3; Preparation of soil sample instrument 1 adopts stainless steel to make diameter 70mm, high 53mm, the thickness 2mm of preparation of soil sample instrument 1 wall.Capacity 200cm fetches earth
3At preparation of soil sample instrument 1 tail end that fetches earth an external thread layer 2 is arranged, and increase a tail-hood 4, tail-hood 4 has internal thread tail-hood 4 can be enclosed within preparation of soil sample instrument afterbody and screws, preparation of soil sample instrument tail-hood 4 center fixation have rotating shaft 5, a hole that penetrates rotating shaft is arranged in the rotating shaft 5, can the Metallic rod 6 that a length surpasses preparation of soil sample instrument tail-hood diameter be through in the rotating shaft by this hole, by rotating metallic bar 6, can drive preparation of soil sample instrument 1 easily and rotate, preparation of soil sample instrument 1 is successfully entered in the hard soil sample 7.The edge of a knife 3 end faces are del during 1 work of preparation of soil sample instrument, and the drift angle of inverted triangle is 10 degree isosceles triangles, and height is 9mm.Point of a knife is downward, the cutter tail in the projection width of vertical direction greater than preparation of soil sample instrument 1 wall thickness 1mm.The triangle top is downward-sloping from inside to outside in the contact position of preparation of soil sample tool wall, and the horizontal line of triangle top in the contact position of preparation of soil sample tool wall of edge of a knife end face is evenly distributed with hole, and hole penetrates preparation of soil sample tool wall.Screw-in preparation of soil sample instrument will easily pass soil sample when soil sample weight tray 8 is taken a sample like this, carries out soil sample and produces.
