Description
Technical field
This application involves excavate to acquire instrument field, especially soil sampling apptss.
Background technique
Soil sampling refers to the method for acquisition pedotheque, laying and sampling technique including sampling.Section soil sample is adopted, is answered
It is carried out after section is observed and recorded.
The surface dust on most surface layer should be pruned first by section trimming, cleaning before sampling, it is then layer-by-layer from top to bottom by level again
It is sampled from center typical parts.
On the basis of understanding pollution sources, pollution modes and pollution history and status, comprehensive type for considering soil,
Situations such as soil parent material, landform, natural vegetation or crops, arranges sampled point.The time and quantity for acquiring pedotheque, depending on adopting
Depending on the object and purpose of collection.
It because of complex procedures in soil sampling, mostly uses manual operation to be sampled greatly at present, but is just needed when artificial sample
Multiple back and forth soil sampling is carried out to guarantee the client's property and accuracy of sampling result for different positions, this is resulted in
It needs to expend biggish manual operation and longer time when artificial sample to guarantee quantity of sampling quantity.In order to mitigate in manual operation
Deficiency, many companies also devise many auxiliary tools at present, but these auxiliary tools can only all assist completion table mostly
The cleaning of face soil replaces manual operation by machine to simple some processes, but function is relatively single, can not solve well
Certainly manual sampling low efficiency, time-consuming and laborious problem；Especially when the soil to different location, different depth layer is sampled
Current mode and tool can not more effectively meet the needs of in sampling operation.

Lateral wall matches.
A squeeze grip 18 is respectively fixedly connected in the top two sides of circular base 1.
By pressing the stability when guarantee whole device that can be assisted operation.
Working principle:
After the present apparatus powers on, hydraulic station 4 is controlled by operator, thus realize the control to Powered Propulsion power device, control
It is extended downwardly device processed, and when multistage hydraulic cylinder 5 drives the wellbore part of its bottom to contact ground, operator opens drilling in turn
The switch of motor 9 controls drill bit 10 at this time and rotates, and the thrust that multistage hydraulic cylinder 5 still keeps down at the same time can successively make
It obtains drill bit 10 to be rotated down, with the difference of screw-in depth, and the next progress appropriate of bottom depth sampled as needed is each
The control of component stalling；The drilling outer diameter of drill bit 10 is set greater than to the maximum outside diameter of connection vertical tube 8, so that brick drilled out
Cavity can continue deeper into directly down for connection vertical tube 8, blocking interference will not be generated, when the drill bit of control whole device bottom
10 when being drilled into designated depth, and operator controls hydraulic station 4, and then controls each reciprocal propulsion cylinder 12 and move, reciprocal propulsion cylinder
When 12 piston rod is protruding, while and control sampling motor 15 and rotate, therefore the annular auger of its end may be implemented
First 19 obliquely, it rotates outward, current soil is sampled after being pierced by sampling hole 17, after drilling, soil has part and falls
It, can repeatedly the reciprocal propulsion cylinder of control more than 12 times in drilling in order to which the amount for guaranteeing sampling is more more into sample storage cylinder 16
Realization extends and retracts, and is loosened, is drilled to soil layer, will fall in sample storage cylinder after soil loosens so as to effectively drive
In 16.After the completion of sampling, according to the reverse operating of aforesaid operations, so that it may all parts aftertaste is realized, finally by the soil of sampling
Earth is delivered up to more than ground, is then taken the soil being stored in sample storage cylinder 16 using the instrument of sampling by operator
Out.
Above-mentioned specific embodiment cannot function as the limitation to the application protection scope, for the technology people of the art
For member, any alternate modification or transformation made to the application embodiment are all fallen in the protection scope of the application.
Place is not described in detail by the application, is the well-known technique of those skilled in the art of the present technique.
