Specific embodiment
With reference to the accompanying drawings and examples, specific embodiments of the present invention will be described in further detail.Implement below
Example is not intended to limit the scope of the invention for illustrating the present invention.
Fig. 1 is a kind of structural schematic diagram of undisturbed soil sampler according to the present invention, and Fig. 2 is one kind according to the present invention
The top view of undisturbed soil sampler, referring to figs. 1 and 2, a kind of undisturbed soil sampler includes: vertical clapboard 2 and two
A band sword semicircle drilling pipe 1, the bottom of the vertical clapboard 2 are fixed with round breast boards 8, and the internal diameter with sword semicircle drilling pipe 1 is greater than
1~3mm of diameter of round breast boards 8, the two sides of the vertical clapboard 2 are respectively equipped with the first support base 10 and the second support base 7,
The vertical direction of first support base 10 and second support base 7 in the side close to the vertical clapboard 2 is respectively equipped with
Identical semi-circular grooves 11, the diameters of the semi-circular grooves 11 are greater than the diameter of the round breast boards 8, and described first
It supportting seat 10 and the vertical clapboard 2 welds, the vertical clapboard 2 passes through detachable connection with second support base 7, so that
Two semi-circular grooves 11 form the groove concentric with the circle breast boards 8, two band sword half-round drills when sampling
Pipe 1 is inserted into the groove and surrounds the round breast boards 8.
Specifically, it is welded due to first support base 10 with the vertical clapboard 2, vertical clapboard 2 and second is supported
Seat 7 is detachably connected by hanging groove, and the first support base 10, vertical clapboard 2 and the second support base 7 form an overall structure,
So that two merging of semi-circular grooves 11 form groove, groove and round breast boards 8 are concentric, are divided among groove by vertical clapboard 2
For two parts.Also, the internal diameter with sword semicircle drilling pipe 1 is greater than 1~3mm of diameter of round breast boards 8, convenient for band sword semicircle drilling pipe
1 smooth sliding in the trench, and combined with round breast boards 8 and shearing force is formed to soil sample.When sampling, by two band swords half
Round bur pipe 1 is inserted into groove, and round breast boards 8 is equivalent to the top surface of soil, is played a supportive role.Then to band sword semicircle drilling pipe
Apply pressure, so that it is drilled into depth described in sampling soil, fine rotation vertical clapboard 2 is thorough with lawn by soil sample
Separation lifts two bands sword semicircle drilling pipe 1 and vertical clapboards 2, so that earth pillar completely be taken out then up.Then will vertically every
Plate 2 and the second support base 7 are split, and the semi-circular grooves 11 being inserted into the second support base are dismantled, entire earth pillar can be complete
Whole taking-up carries out the soil water experiment of next step.After for experiment, the soil sample not being destroyed is placed back in two
In a semi-circular grooves 11, before newly putting back in the lawn soil of sampling, soil sample can continued growth.
A kind of undisturbed soil sampler provided by the above embodiment is cooperated using band sword semicircle drilling pipe and breast boards, sampling
When to be able to maintain soil sample complete, do not influence periphery lawn growth, and using detachable point of clamping support, facilitate soil sample
It picks and places, the soil sample after observing and testing can be restored to lawn as former state, effectively fill up the lawn pit that sampling generates, protected
Demonstrate,prove the planarization on lawn.
Content based on the above embodiment, referring to figs. 1 and 2, vertical clapboard 2 pass through removable with the second support base 7
It unloads and is connected as hanging groove and hook connection.The mode being detachably connected has very much, comprising: screw rod is connected with nut, hanging groove and hook
It connection, card slot and snaps connection and hinge is connect.For the ease of the separation of vertical clapboard 2 and the second support base 7, this implementation
Example selection hanging groove and hook connection type, hanging groove is secured with the connection type for linking up with cooperation and is readily disassembled, and facilitates taking for pattern
It puts, it is convenient to operate.
Content based on the various embodiments described above, referring to figs. 1 and 2, vertical clapboard 2 and the second support base 7 pass through extension
The connection of slot and hook specifically includes: being symmetrical arranged two layers of totally four hanging groove 5, the second support in 2 two sides of vertical clapboard
7 two sides of seat are symmetrically arranged with four hooks 6 matched with four hanging groove positions, and four hanging grooves 5 are corresponding with four hooks 6 to match
It closes.When vertical clapboard 2 is connect with the second support base 7, the hook 6 is first put into inside hanging groove, the opening of hanging groove is directed at
The second support plate 7 is placed downwards at position, so that hook is fitted close with hanging groove, and by the second support plate 7, hammer is real downwards with soft hammer.
Similarly, when taking out soil sample, the second support plate 7 is tapped upwards using soft hammer, so that each 6 corresponding hanging groove 5 of hook
Separation, separates the second support plate 7 with vertical clapboard 2, to facilitate the acquisition and reduction of lawn soil sample.
Content based on the various embodiments described above, referring to figs. 1 and 2, the top of first support base 10 are symmetrically set
There are two rotation card 9, the side of the vertical clapboard is symmetrically arranged with two card slots 4, the vertical clapboard 2 with described second
Support seat 7 is respectively clamped into two card slots 4 by two rotation cards 9 when 6 cooperation of hanging groove 5 and hook, and pushes down the second support base 7
Top.
Specifically, in order to further fix the connection of the second support base 7 with vertical clapboard 2, when hanging groove 5 is corresponding with linking up with 6
After mating connection, the rotation card 9 that four hanging grooves 5 link up with the setting of 6 corresponding matchings with four is gone in corresponding card slot 4, is blocked
Piece 9 is vertical with vertical clapboard 2 at this time, and is pressed in the top of the second support base 7, is equivalent to and applies a downward pressure to hook 6
Power so that the second support base 7 connect with vertical clapboard 2 it is stronger, guarantee whole device it is steady during soil sampling
It is qualitative.Wherein, the fixed form of rotation card 9 can connect for nut with screw rod, after card 9 is caught in card slot 4, by tightening
Nut can make rotation card 9 stronger.
A kind of undisturbed soil sampler provided by the above embodiment, by being symmetrically arranged with two at the top of the first support base
