15, track groove 16 is equipped on guide rail.As shown in Figure 3, Figure 4, threaded hole is respectively equipped on the top of the left and right side walls of main casing
17。
It is respectively equipped with side body 2 in the left and right side of main casing, as shown in fig. 7, side body is also in cuboid
Four sidewall thickness of hollow structure, the open top of side body, side body are consistent and with a thickness of 1-3mm.In the inside of side body
Equipped with partition 21, the inner cavity of side body is divided into the first operating cavity 22 and the second operating cavity 23 by partition, wherein the first operating cavity
Bottom is enclosuring structure, and the bottom of the second operating cavity is uncovered structure.It is equipped with otic placode 24 at the top of side body, in side body
It is respectively equipped with the positive stop strip being slidably matched with track groove on forward and backward side wall, the positive stop strip on side body is placed in track when installation
In slot, and slide downward side body is until the bottom of side body is concordant with the bottom of main casing.At this point, main casing and side body it
Between may only be relatively moved in vertical direction, it is relatively fixed between main casing and side body to realize, in otic placode and screw thread
Jackscrew 25 is set between hole.Main, side body is stainless steel metal part.
As shown in Fig. 2, Fig. 7, it is equipped with the second through-hole 26 on the side wall of side body, side body and main casing are mounted on one
After rising, the second through-hole is connected to first through hole.It is equipped with third through-hole 27 on partition, is equipped with inclination in the bottom of the second operating cavity
It face 28 can be to two sides impacting soil, to avoid squeezing main casing when the setting of the inclined surface is so that side body is pressed into soil
Soil immediately below body.
Control stick 3 is straight-bar, finger-hole 31 is equipped at the top of control stick, in order to protruding into for operator's finger.It is manipulating
The lower part of bar is equipped with groove 32, is equipped with trunnion 33 in the bottom of control stick, is hingedly equipped with support by articulated shaft 34 on trunnion
Plate 35, supporting plate are pyramidal structure, and the big end and trunnion of supporting plate are hinged.It is equipped with the first locking hole 36 in the big end of supporting plate, in trunnion

Bolt 5, supporting plate is in horizontal plane at this time.Torsional spring is equipped between supporting plate and control stick, as shown in figure 12, in the effect of torsional spring
Angle in obtuse angle between lower pallet and control stick, and when control stick is in a vertical state, supporting plate is obliquely installed obliquely.
Control stick can be placed in the first operating cavity, can also be placed in the second operating cavity.Control stick is placed in the first behaviour
When making intracavitary, overturning supporting plate makes supporting plate close to control stick, then protrudes into the lower part of control stick in the first operating cavity, control stick
During moving down, supporting plate and baffle contacts and compressed under the action of torsional spring.
Escape groove 38 is equipped on the outer wall on control stick top, the setting of escape groove is for avoiding jackscrew.Control stick lower part
Groove, for avoiding supporting plate.For blade is arranged in the bottom of main casing and side body convenient for sampling.
Application method of the invention is described below:
(1) side body is installed on guide rail on a main housing, and is fixed side body and main casing locking by jackscrew；
(2) handle is held, as shown in figure 9, by main casing, side body indentation soil, according to the graduation mark on main casing,
The depth in main casing indentation soil can be observed；After main casing is pressed into soil, part soil enters the second behaviour of side body
Make it is intracavitary, sampling soil then enter in main casing；
(3) as shown in Figure 10, control stick is lifted upwards, as shown in figure 8, at this time in the small end of supporting plate and the second operating cavity
Soil contact, and the small end of supporting plate is extend into soil and supporting plate and control stick across third through-hole under the action of torsional spring
Angle be gradually increased；After control stick above proposes a distance, jackscrew main, between side body is unclamped, two side bodies are taken
Out；The soil above the second operating cavity inner shoe is removed with side body at this time；
(4) soil in side body is poured out, is then reinstalled side body on a main housing, by first on supporting plate
Locking hole is aligned with the second locking hole on trunnion and passes through locking bolt and fixes supporting plate and control stick locking, at this time at supporting plate
In in horizontal plane；Then it lodges external force pallets level is inserted into sampling soil, in the process, supporting plate sequentially passes through second,
First through hole, and after control stick and side body inner wall contact, supporting plate reaches range；When supporting plate reaches range, two
It can have certain spacing between supporting plate, the small end of two supporting plates can also contact.
(5) handle is held, lifts main casing upwards, side body is moved up as main casing synchronizes at this time, as shown in figure 13, and
Sampling soil is then separated by supporting plate.
In entire sampling process, the side extruding force very little that the intracorporal sampling soil of main casing is subject to can be ignored.Main casing
The extruding force very little that soil immediately below body is subject to, therefore lower section soil can also ignore the active force of sampling soil, at this time
Sampling soil substantially remains in the form in soil.
