Description

Columnar soil sampling pipe

Technical Field

The utility model belongs to the technical field of soil sampling equipment technique and specifically relates to a column soil sampling pipe.

Background

The collection of the soil sample is the basic work in the fields of soil science research and geological survey, and provides a material basis for the determination of the physical and chemical properties of the soil sample. Wherein column soil sampling pipe, jam the transparent plastic tubing inside the pile driver drilling rod, the drilling rod front end drill bit is beaten, soil can be stayed and is got in the transparent plastic tubing, the realization is to the collection of soil, at the in-process of this soil collection, the transparent plastic tubing inner wall of current use is more level and smooth, the soil in the in-process plastic tubing of pulling out the drilling rod is the partly that contracts easily, simultaneously, it is internal that soil in the plastic tubing exists the pipe to get into, be difficult to take out, further soil data collection not convenient for.

SUMMERY OF THE UTILITY MODEL

In order to overcome current soil acquisition pipe collection inefficiency not enough, the utility model provides a column soil sampling pipe fills in the drilling rod with transparent plastic pipe, and the drill bit is connected to the drilling rod front end, then the drilling rod is gone into the end of the ground and is realized the collection of transparent plastic pipe to soil, when extracting the drilling rod, the pawl of transparent plastic pipe tip increases the frictional force of soil and transparent plastic pipe inside wall, simultaneously, takes out transparent plastic pipe in the follow drilling rod, then takes out behind the sample closing plate and take a sample to the soil in the transparent plastic pipe and collect.

The utility model provides a technical scheme that its technical problem adopted is: the utility model provides a column soil sampling pipe, includes the drilling rod, and the drilling rod front end is equipped with the drill bit, the stopper has transparent plastic tubing in the drilling rod, be equipped with the pawl on the cavity wall in transparent plastic tubing front end, be equipped with sample closing plate on the transparent plastic tubing pipe wall, and a transparent plastic tubing port is equipped with the buckle closure.

Furthermore, the drill comprises a transparent plastic pipe, wherein one end of the transparent plastic pipe is provided with inverted teeth, the end of the inverted teeth is arranged at the root part of the drill, and the inverted teeth face the inner side of the transparent plastic pipe.

Furthermore, a sampling port for connecting a sampling closing plate is arranged on the wall of the transparent plastic pipe.

Further, be equipped with the latch including sample closure plate both sides, and the oral surface of sample connection offers the draw-in groove that is used for latch inlay card to alternate.

Furthermore, the device comprises a drill bit and a drill rod which are in threaded fit connection, and a transparent plastic pipe is in threaded fit connection with a buckle cover.

The beneficial effects of the utility model are that, the utility model discloses a column soil sampling pipe, in advancing the drilling rod with the transparent plastic pipe stopper, the drill bit is connected to the drilling rod front end, then the drilling rod is gone into the collection of the end of the ground realization transparent plastic pipe to soil, when extracting the drilling rod, the pawl of transparent plastic pipe tip increases the frictional force of soil and transparent plastic pipe inside wall, the problem of the easy roll-off transparent plastic pipe intracavity of soil has been solved, and simultaneously, take out transparent plastic pipe from the drilling rod, then take out the collection of taking a sample to the intraductal soil of transparent plastic behind the sample closing plate, this adopts simple structure, and convenient operation has improved the efficiency of soil collection sample.

Drawings

The present invention will be further explained with reference to the drawings and examples.

Fig. 1 is a schematic structural diagram of the present invention;

FIG. 2 is a schematic view of the internal structure of FIG. 1;

FIG. 3 is a partial enlarged view of FIG. 2B;

FIG. 4 is a schematic structural view of the transparent plastic tube of FIG. 2;

fig. 5 is a cross-sectional view at fig. 4A-a.

In the figure, 1, a drill rod, 2, a drill bit, 3, a transparent plastic pipe, 4, inverted teeth, 5, the transparent plastic pipe, 6, a buckle cover, 7, a sampling port, 8, a latch and 9, a clamping groove are arranged.

Detailed Description

Fig. 1 is the structure characterized by of the utility model, the drill rod 1 is filled with transparent plastic pipe 3, be equipped with pawl 4 on the cavity wall in the transparent plastic pipe 3 front end, be equipped with sample closing plate 5 on the transparent plastic pipe 3 pipe wall, and 3 ports of transparent plastic pipe are equipped with buckle closure 6.

Referring to fig. 2 and 3, the transparent plastic tube 3 is provided with the inverted teeth 4, one end of the inverted teeth 4 is arranged at the root of the drill 2, and the inverted teeth 4 face the inner side of the transparent plastic tube 3.

Referring to fig. 4 and 5, a sampling port 7 for connecting the sampling closing plate 5 is formed on the wall of the transparent plastic tube 3.
