Embodiment: a kind of double-jacket tube soil sampler, as depicted in figs. 1 and 2, including outer tube 1, inner sleeve 2, drill bit 3,
Leak jacket 4(refers to Fig. 3) and top cap 5.Outer tube 1 is cylindrical and inner hollow, and inner sleeve 2 is cylindrical and its diameter
Less than the diameter of outer tube 1,2 inner hollow of inner sleeve, inner sleeve 2 and outer tube 1 have multiple and are vertically arranged, and adjacent two
The adjacent both ends of a inner sleeve 2 or two neighboring outer tube 1 are threadedly coupled, and inner sleeve 2 is located at the inside of outer tube 1, are bored
First 3 are vertically arranged and are located at the underface of outer tube 1, and the upper end of drill bit 3 is threadedly coupled with the lowermost outer tube 1, drill bit 3
Inner hollow, drill bit 3 in back taper and the bottom edge of its drill bit 3 in the shape of a spiral.When spiral helicine drill bit 3 is drilled, drill bit 3
Pierce it is more laborsaving in soil layer, downwards probing when it is more convenient.
Leak jacket 4 is cylinder, and leak jacket 4 is located at the inner sidewall phase of 3 inside of drill bit and its inner sidewall and leak jacket 4
Patch, the top of leak jacket 4 is connect with the bottom thread for being located at the lowermost inner sleeve 2, in this way when drill bit 3 rotates downward excavation
When, soil is entered out of drill bit 3 in leak jacket 4, is then entered in inner sleeve 2 by leak jacket 4.
Outer tube 1 it is identical with the quantity of inner sleeve 2 and both number depending on excavate depth depending on, be connected through a screw thread
Mode outer tube 1 and inner sleeve 2 are fixed, continue growing 1 He of outer tube when 3 excavating depth of drill bit is deeper in this way
It is more convenient when inner sleeve 2.
Sample tap 21 is offered as shown in figure 3, being located on the side wall of the inner sleeve 2 of lowest part, is equipped with and takes in sample tap 21
Template 22, the side of sampling plate 22 and the inner sidewall of sample tap 21 carry out hingedly, and sampling plate 22 is at the position of sample tap 21
It is installed with link block, bolt 23 is threaded on link block.In this way by the inner sleeve 2(in lowermost end refer to Fig. 1) on cut with scissors
Template 22 is picked up, sampling plate 22 is fixed on inner sleeve 2 by bolt 23 when drill bit 3 is drilled downwards, is taken out when by inner sleeve 2
When, bolt 23, which is backed out, can open sampling plate 22 and be sampled to the soil of bottom, more convenient.
As shown in Figure 4 and Figure 5, leak jacket 4 is cylindrical and inner sidewall bottom is hingedly there are four piece 41 is swung, and four are put
Movable plate 41 combines the cone for forming upper end closed, and the lower end surface for swinging piece 41 is circle compatible with the inner face of leak jacket 4
Arcuation, each lower end for swinging piece 41 is hinged with the inner sidewall of leakage prevention sheet, and each side wall for swinging piece 41 is interior with leak jacket 4
Spring 42 is equipped between side wall, the both ends of spring 42 are fixedly connected with the side wall of leak jacket 4 and swing piece 41 respectively, adjacent pendulum
The side wall of movable plate 41 is mutually close to.
Before being sampled to soil, multiple swing pieces 41 under the action of a spring 42 mutually be close to, to soil into
When row sampling, drill bit 3(refers to Fig. 1) drive outer tube 1(to refer to Fig. 2 with reference to Fig. 1) and inner sleeve 2() move down, pollution
Soil enters in leak jacket 4 from drill bit 3, then opens multiple swing pieces 41 and then enters in inner sleeve 2, when drill bit 3 is dug
Specified depth is dug later to pull out inner sleeve 2 together with outer tube 1, since soil herein is damp soil, lower part
A part falls off to which multiple swings pieces 41 close and tightly seal the bottom of leak jacket 4, in this way the sewage also in inner sleeve 2 because of
It is multiple swing pieces 41 closures and can not flow out, this kind of soil sample collector can prevent sewage from flowing out during use in this way
To reduce the harm to environment.
Due to swing piece 41 bottom be fixedly connected with the bottom of leak jacket 4, in order to prevent swing piece 41 rotation when
It waits and leak occurs, be installed with arc-shaped water-proof block 43 at the corresponding position for swinging 41 bottom of piece on the inner sidewall of leak jacket 4.
The bottom for swinging piece 41 during swinging piece 41 and rotating in this way can be still affixed on the top of water-proof block 43, and sewage will not overflow
Out.
In order to further prevent sewage overflows, swing 41 side of piece side wall be arranged convex block 44, the length of convex block 44 with
The equal length of piece 41 is swung, swings and offers groove 45 compatible with convex block 44, adjacent pendulum on the side wall of 41 other side of piece
Convex block 44 on movable plate 41 can be embedded in groove 45, and groove 45 is installed with rubber pad on the side wall of 44 side of convex block
46.When swing piece 41 under the action of a spring 42 seals the bottom of leak jacket 4, a convex block 44 swung on 41 side wall of piece
Be embedded it is adjacent swing piece 41 on groove 45 in, convex block 44 and squeeze rubber block to guarantee two swing pieces 41 cooperate closely,
Sewage is further prevented to flow out.
The cross section for swinging piece 41 is to recessed arc-shaped, and pollution in this way enters in leak jacket 4 more smoothly, works as pendulum
During movable plate 41 springs back under the action of a spring 42 and seals the bottom of Antileaking plate, a part of soil can be more convenient
Ground, which enters, to be swung between piece 41 and the inner sidewall of leak jacket 4, so that swinging piece 41 can be more easily by the bottom of housing
It seals.
Top cap 5 is cylindrical and is horizontally disposed with, and the lower end of top cap 5 is threadedly coupled with outer tube 1, the upper end of inner sleeve 2 with
The bottom surface of top cap 5 is close to, and offers multiple exhausts being connected to up and down being vertically arranged at the position of the corresponding inner sleeve 2 of top cap 5
The excavating resistance of drill bit 3 is reduced, the outside of top cap 5 is installed with horizontally disposed so that air in inner sleeve 2 be facilitated to be discharged in hole 51
Connection ring 52, the lateral wall two sides of connection ring 52 are installed with handle 54, and there are four stabilizer blade 53, branch for the bottom fixation of connection ring 52
The lower end of foot 53 can be affixed with ground, easier for installation in this way, when the rear leg 53 installed can fix on the ground, be protected
Demonstrate,prove the stability that drill bit 3 is drilled.
The above is only the preferred embodiment of the utility model, and the protection scope of the utility model is not limited merely to
Above-described embodiment, technical solution belonging to the idea of the present invention belong to the protection scope of the utility model.It should refer to
Out, for those skilled in the art, it is without departing from the principle of the utility model it is several improvement and
Retouching, these improvements and modifications also should be regarded as the protection scope of the utility model.
