Specific embodiment
It is next in the following with reference to the drawings and specific embodiments that the present invention will be described in detail.
Referring to Fig. 1 to 5, a kind of soil sample collector, including rack 1 and the sliding block 2 that can be slided up and down along rack 1；The cunning
Block 2 is driven up and down by several hydraulic pushing devices 3；2 lower face of sliding block is fixed with a first vertical rigid cylinder 22；One
The second transparent rigid cylinder 23 is detachably set in the first rigid cylinder 22, and a transparent third rigid cylinder 24 is set in
In second rigid cylinder 23；Second rigid cylinder 23 is used for soil with what the setting enclosing of 24 mutual spacing of third rigid cylinder circularized
The collection provincialism 25 of earth sampling；It is fixedly connected between second rigid cylinder 23 and third rigid cylinder 24 by several connecting rods 26；
The outer circumference surface of second rigid cylinder 23 is resisted against on the inner peripheral surface of the first rigid cylinder 22；One annular sleeve 6 is detachable
It is set in 23 bottom of the first rigid cylinder 22 and the second rigid cylinder, wraps up the first rigid cylinder 22 and the second rigid cylinder 23
Bottom；6 lower end of annular sleeve is downward tip 61；One dragon shaft 4 is set in vertically in the third rigid cylinder 24；Institute
It states 4 bottom of dragon shaft and is provided with a drill bit 5；The drill bit 5 is extended downwardly outside third rigid cylinder 24；The dragon shaft 4 is by one
The driving rotation of motor 7 being fixed on sliding block 2, ground is delivered to by the soil that drill bit 5 drills through.
Further, the side of 6 second rigid cylinder 23 of package of first annular set has to third rigid cylinder 24
The arc bulge 62 of side protrusion, to prevent the soil for entering collection provincialism 25 from dropping out.
Further, second rigid cylinder 23 and third rigid cylinder 24 are detachable up and down successively by more piece cylinder
Joggle forms.
Further, sliding block 2 is provided with more one slide rails 11 in the rack 1；2 side of sliding block corresponds to sliding rail 11 and divides
It is not provided with multiple sliding slots；The sliding block 2 is slided up and down vertically by the cooperation of sliding slot and sliding rail 11.
Further, 1 lower end of rack is provided with the lug 12 for placing clump weight.
Further, the 22 lower part outer wall of the first rigid cylinder is provided with external screw thread；Be provided in the annular sleeve 6 with
The internal thread of the external screw thread cooperation.
Application method of the present invention：
Sampler is placed on to place ground to be sampled, the clump weights such as stone are placed on lug 12 makes rack 1 firm,
Start motor 7, motor 7 drives dragon shaft 4 and drill bit 5 to rotate, while fluid pressure drive device 3 drives sliding block 2 slowly to move down, hydraulic pressure
Driving device 3 uses hydraulic stem, and particular number and power are not present invention points, and those skilled in the art can be according to tool
Body needs to set, and only need to ensure that sliding block 2 can be moved down steadily；Drill bit 5 contacts ground and drills first, the soil drilled out by
Dragon shaft 4 exports ground, in this way, contacting ground in the first rigid cylinder 22, the second rigid cylinder 23 and third rigid cylinder 24
When, center has produced a hole, therefore squeezes ground in the second rigid cylinder 23 and third rigid cylinder 24 and obtain
Soil, which has, during sample allows bit space, and the resistance that the second rigid cylinder 23 and third rigid cylinder 24 are subject to is greatly lowered, can
To tunnel deeper depth, the pedotheque more deeply spent is obtained；
After the completion of sampling, fluid pressure drive device 3 offers the port for operation with 2 return of movable slider on sliding block 2, from
Port down releases downwards the second rigid cylinder 23 and third rigid cylinder 24, disengages it from the first rigid cylinder 22, whole
After taking out the second rigid cylinder 23 and third rigid cylinder 24, the delamination of soil can be directly observed, needs to detect each section
Soil, which need to only remove each merogenesis, can facilitate taking-up Soil K+adsorption.
The foregoing is merely the embodiment of the present invention, are not intended to limit the scope of the invention, every to utilize this hair
The equivalent structure or equivalent flow shift that bright specification and accompanying drawing content are made directly or indirectly is used in other relevant skills
Art field, is included within the scope of the present invention.
