Abstract

The utility model discloses a kind of ground samplers, including pedestal (1) and sampler (2), it is characterized by: pedestal (1) top is provided with circular hole, internal screw thread is equipped in circular hole, the sampler (2) is hollow tubular structure, it is provided at an outer portion with the external screw thread matched with the circular hole internal screw thread on pedestal (1), sampler (2) upper end is fixed with rotating handle (3), the sampler (2) is made of several sampling unit parts (21) and an excavation device (22), it is fixedly connected between the sampling unit part (21), it is fixed excavation device (22) being located at sampler (2) the lowermost sampling unit part (21) lower end.The utility model using the above scheme, assembles the length of sampler according to depth selection when in use, so that sampler is inserted into soil by screw thread rotation when sampling, reversely rotates taking-up sampler, time saving and energy saving.

Description

A kind of ground sampler
Technical field
The utility model relates to geotechnical engineering sampling equipment technical fields, specifically, are related to a kind of ground sampler.
Background technique
Before carrying out geotechnical engineering, need to be sampled the ground of construction site.Sampling is to carry out to Rock soil Characteristics The work that identification is carried out with sample required for the offer of various laboratory experiments.Ground sampler is to extract lower layer's test soil original Shape soil understands base's property as sample, for making a kind of tool of soil sample analysis before various engineering constructions to construction stratum. Instantly often structure is complicated for traditional ground sampler, not readily portable, and simple sampler then has a single function, and ground takes Sample depth is fixed, and because of the resistance by soil when taking out inside insertion soil and after sampling, when use is relatively elaborate.
Summary of the invention
The purpose of this utility model is that in view of the above-mentioned problems existing in the prior art, proposing one kind can be easy to carry, It requires freely to assemble according to depth selection, facilitates the ground sampler of insertion soil and taking-up.
The purpose of this utility model can be realized by the following technical scheme:
A kind of ground sampler, including pedestal and sampler, the pedestal top are provided with circular hole, are equipped in circular hole interior Screw thread, the sampler are hollow tubular structure, are provided at an outer portion with the external screw thread matched with the circular hole internal screw thread on pedestal, institute It states sampler upper end and is fixed with rotating handle, the sampler is made of several sampling unit parts and an excavation device, described to take It is fixedly connected between sample unit piece, is being located at the fixed excavation device in sampler the lowermost sampling unit part lower end.
Preferably, the sampling unit part is hollow tubular structure, and top round tube diameter is less than lower circular pipe diameter, upper It is equipped with external screw thread on the outside of portion's round tube, the internal screw thread matched with external screw thread on the outside of the round tube of top is equipped on the inside of lower circular pipe, is taken It is connected through a screw thread between sample unit piece.
Preferably, the rotating handle is threadably secured with sampler connect.
Preferably, the excavation device is hollow structure, and top is cylinder, and lower part is reverse frustoconic.
Preferably, the excavation device is threadably secured with sampling unit part and connect.
The utility model using the above scheme, assembles the length of sampler according to depth selection when in use, logical when sampling Crossing screw thread rotation makes sampler be inserted into soil, reversely rotates and takes out sampler, time saving and energy saving.

Fig. 2 is the decomposition texture schematic diagram of the utility model.
In figure, 1, pedestal;2, sampler;21, sampling unit part;22, excavation device;3, rotating handle.
Specific embodiment
It is specific embodiment of the utility model and in conjunction with attached drawing below, the technical solution of the utility model is done further Description, but the utility model is not limited to these examples.
A kind of ground sampler, including pedestal 1 and sampler 2,1 top of pedestal are provided with circular hole, set in circular hole Have an internal screw thread, the sampler 2 is hollow tubular structure, be provided at an outer portion with matched with the circular hole internal screw thread on pedestal 1 it is outer Screw thread, 2 upper end of sampler are fixed with rotating handle 3, and the sampler 2 is by several sampling unit parts 21 and an excavation device 22 form, and are fixedly connected between the sampling unit part 21, fix being located at 2 the lowermost sampling unit part of sampler, 21 lower end Excavation device 22.The sampling unit part 21 is hollow tubular structure, and top round tube diameter is less than lower circular pipe diameter, in top circle It is equipped with external screw thread on the outside of pipe, the internal screw thread matched with external screw thread on the outside of the round tube of top is equipped on the inside of lower circular pipe, sampling is single It is connected through a screw thread between element 21.The rotating handle 3 is threadably secured with sampler 2 to be connect.The excavation device 22 is Hollow structure, top are cylinder, and lower part is reverse frustoconic.The excavation device 22 and 21 company of being threadably secured of sampling unit part It connects.
When the utility model is used, selecting several sampling unit parts 21 fixed the depth of ground sampling as needed Connection after assembling sampler 2, is fixed in the fixed excavation device 22 in 21 lower end of the lowermost sampling unit part in 2 upper end of sampler Pedestal 1 is placed on the position for needing to sample by good rotating handle 3, and 2 lower end of sampler is then passed through circular hole on pedestal 1, rotation again Rotating handle 3, sampler 2 will move downward, and after ground depth selection needed for reaching, rotate backward rotating handle 3, will sample Device 2 takes out, and can be obtained the ground sampling of required depth.
The specific embodiments described herein are merely examples of the spirit of the present invention.The utility model institute Belonging to those skilled in the art can make various modifications or additions to the described embodiments or using similar Mode substitute, but without departing from the spirit of the present application or beyond the scope of the appended claims.
Although there is used herein pedestals 1;Sampler 2;Sampling unit part 21;Excavation device 22;The terms such as rotating handle 3, but A possibility that being not precluded using other terms.It is practical new the use of these items is only for being more convenient to describe and explain this The essence of type, it is contrary to the spirit of the present invention to interpret them as any one of the additional limitations.
