Description
Technical field
The invention belongs to soil sampling apptss technical fields, and in particular to a kind of undisturbed soil sampling device.
Background technique
Soil sampling is the important method of activety fault, environmental monitoring, prevention and cure of pollution, but during present sample
There are problems that different soil disturbance, pollution, prevent the sample of acquisition is from really reflecting undisturbed soil information；In addition, In
Some soil layers deep area when carrying out soil science research, needs accurately to obtain the pedotheque of different levels, Cai Nenggeng
Good supposition erosion and deposition, Water Transport information.
It at present when carrying out soil sample, is mostly sampled using geotome, geotome is pierced by soil by spiral way
When in layer, then reversely rotating pull-out again, and soil sample is easily fallen in geotome when rotating backward, while obtaining soil sample in drill bit
Multi-pass crosses way of propelling taking-up, is easily destroyed soil sample characteristic, it is difficult to obtain undisturbed soil, be not easy to study；
Meanwhile traditional geotome is when in use, multi-pass exerts a force on geotome top, not using pole when geotome is longer
It is convenient.
Summary of the invention
The problem of mentioning in technology based on the above background, the present invention provides a kind of undisturbed soil sampling devices, for solving
Traditional geotome is difficult to obtain undisturbed soil, while needing to exert a force on geotome top when in use, causes when geotome is longer
Problem inconvenient for use.
The technical solution adopted by the invention is as follows:
A kind of undisturbed soil sampling device, including positioning plate and geotome are equipped with inner tube, the positioning in the geotome
The first via hole is offered on plate, the geotome is actively located in the first via hole, and the geotome includes break ground cylinder and transmission
Cylinder, the cylinder that breaks ground are equipped with the screw thread that breaks ground, and the transmission cylinder is equipped with motion thread, the spiral shell of the motion thread and the screw thread that breaks ground
Line is contrary, axial outside the transmission cylinder to offer first sliding groove, and sliding sleeve is equipped with transmission ring on the transmission cylinder, described
The internal diameter of transmission ring is greater than the outer diameter of transmission cylinder, and the transmission ring inner wall is integrally formed with the cunning to match with first sliding groove
Block is detachably equipped with extension bar on the transmission ring, and the positioning plate top sets the trip-out nut to match with transmission cylinder, institute
Stating trip-out nut includes two identical half round nuts, and two half round nut tops offer card slot, in the card slot
Restraining position ring block is installed, transmission cylinder top inner wall offers the first link slot, and the transmission cylinder is dismantled by the first link slot
Extending is installed, the extending lower end is equipped with the connecting cylinder to match with the first link slot, and the connecting cylinder and first connect
Connect cylinder is threadedly coupled, and the extending upper end also offers the first link slot.
Based on the above technical solution, the present invention has also done following improvement:
Further, the geotome inner wall offers the first blind hole, and said inner tube is arranged in the first blind hole, said inner tube
Internal diameter it is identical as geotome bottom end internal diameter.The caliber of inner tube is identical as geotome bottom end internal diameter, takes when taking soil
Soil in earth boring auger can be directly entered internal tube, to reduce soil to the resistance for the brill that breaks ground, being conducive to break ground is drilled into ground
Under.
Further, the first blind hole inner wall offers the second blind hole, and the depth dimensions of second blind hole are less than first
The depth dimensions of blind hole.Gap is formed between inner tube and geotome under the action of the second blind hole, second after the completion of taking soil
Under the action of blind hole convenient for take out inner tube, when pedotheque is loosely organized or moisture content is higher, be not in because soil sample with take
Sample inside pipe wall frictional force is insufficiently resistant to the problem of outer wall and soil body frictional force, causes the soil sample taken out loss larger, can not obtain
The problem of to undisturbed soil.
Further, said inner tube includes two semicircular cylinders, and the semicircular cylinder side axially offers the second link slot, another
Side is axially arranged with the connection bump to match with the second link slot.Constituting inner tube by two semicircular cylinders can directly open in acquisition
Portion's soil, survivable soil characteristic, convenient for obtaining undisturbed soil.
Further, it is equipped on the positioning plate and is welded with bracket, lantern ring, the lantern ring top are installed on the bracket
The third blind hole to match with transmission ring is offered, the transmission ring is located in third blind hole, the third blind hole internal diameter
Greater than the internal diameter of transmission ring.Under the action of lantern ring and bracket, transmission ring makes the height of transmission ring by lantern ring load-bearing when breaking ground
Degree remains unchanged, consequently facilitating rotation extension bar, easy to use.
Further, magnetic patch is installed in the lantern ring bottom end, and the stop collar is metal iron hoop.It, will when dismantling trip-out nut
Geotome pulls up, and stop collar is sucked by magnetic patch and again puts down geotome, that is, can be taken off stop collar, easy to use.
Further, the lantern ring is equipped with limited post in the third via hole in offering third via hole in third blind hole,
The transmission ring outer wall offers second sliding slot in third via hole corresponding position, and the limited post is arranged in second sliding slot.In
When soil being taken to complete to need to take out geotome from underground, due to necessarily having left soil in first sliding groove, on limit geotome
Transmission ring when rising, the drag effect underdrive ring that soil is necessarily left in first sliding groove be easily detached from lantern ring, and limited post is set
Meter, the limited post penetrated in second sliding slot can carry out axial limiting to lantern ring, avoid transmission ring from being detached from lantern ring, at this time in sliding block
It can be cleared up soil is remained in first sliding groove under effect.
Further, the transmission ring upper end offers T-slot, and the T-slot is located at second sliding slot top, the T-slot

Power rod set is located on T-connecting piece.Extension bar is convenient for disassembly and assembly, is easy to use, while T-slot is located at second sliding slot top, avoids
Limited post interferes extension bar rotation.
Further, the geotome top is equipped with capping, and the capping includes cover board, and the cover board bottom end is integrally formed
There is connecting cylinder.Inner tube top can be pushed down under the action of capping, inner tube 4 is avoided to loosen, while also by the capping of connecting cylinder 62
It is mountable on 6 top of extending, easy to use, limitation is smaller.
Beneficial effects of the present invention:
1, geotome includes breaking ground cylinder and transmission cylinder, transmission cylinder and is existed on the contrary with the hand of spiral that breaks ground on cylinder, then takes soil
The taking-up for completing to need is broken ground when boring, and trip-out nut is fastened on transmission cylinder, continues to rotate in same direction geotome in trip-out nut
Under the action of can extract geotome, since geotome rotates in same direction in use, be beneficial to prevent inside geotome
Soil slides, and is conducive to obtain undisturbed soil；
2, inner tube is installed in geotome, inner tube includes two semicircular cylinders, and inner tube, which is taken out, to open can obtain undisturbed soil,
Avoid damage to soil characteristic；
3, geotome upper end is equipped with the first link slot and can carry out deep layer by the mountable extension rod of the first link slot and take soil,
Simultaneously because sliding sleeve is equipped with transmission ring on transmission cylinder, first sliding groove and sliding block under the action of, transmission ring can be in transmission cylinder
