In work, it is also desirable to a kind of light boring tool, shallow stratum can be carried out and fetched earth discriminating lithology.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of portable probing simple in construction, easily operated and taken
Soil working tool.
To solve the technical scheme that above-mentioned technical problem is used：A kind of portable probing is fetched earth instrument, including by it is lower extremely
On the drill bit of detachable connection, the pipe fitting that fetches earth, connection tube head and drilling rod successively, the pipe fitting that fetches earth is by two to Semi-folding
Semicanal is constituted, and is run through and is communicated with the tube intracavity that fetches earth in the middle part of the drill bit, and the drill bit end forms cutting edge.
Further, the intracavity diameter of the pipe fitting that fetches earth gradually is increased by bottom to top.
Further, there is the connection cavity communicated with the tube intracavity that fetches earth inside the connection tube head, in the connection
Tube head side wall is communicated provided with least one through hole with to connect cavity with the external world.
Further, the blade angle of the cutting edge is 18 ~ 20 degree.
Further, the drilling rod is made up of more piece head and the tail detachable connection.
Beneficial effect：This portable probing is fetched earth in instrument, and the pipe fitting that fetches earth uses the semicanal structure type to Semi-folding, carries
After brill, it can conveniently dismantle and fetch earth the soil body in pipe fitting and put core by depth order, be easy to technical staff to distinguish rock
Soil layer, edit and record and shoot and fetch earth（Core）Photograph.Moreover, the probing is fetched earth, instrument is made up of multiple part dismountables, when carrying
After brill, dismounting has been filled with the pipe fitting that fetches earth of the soil body, and installs other one and fetch earth pipe fitting, does not influence not only so to continue drilling to take
Soil, nor affects on and has been filled with the pipe fitting that fetches earth of the soil body and further dismantle and put the soil body, that is, meet quality and improve work effect again
Rate.
Brief description of the drawings
The utility model is described further with reference to the accompanying drawings and examples；
Fig. 1 is the structural representation of the utility model embodiment；
Fig. 2 is the structural representation of pipe fitting of fetching earth in the utility model embodiment；
Fig. 3 is the diagrammatic cross-section of connection tube head in the utility model embodiment.
Embodiment
Referring to figs. 1 to Fig. 3, a kind of portable probing of the utility model is fetched earth instrument, including detachable successively from the bottom to top
