Specific embodiment
As shown in Fig. 1~Fig. 2, a kind of undisturbed soil sampling cutter with cut-out closing knife unit, including sampling cutter 10,
Storage cutter 20 and cut-out closing cutter 30；The bottom external cylindrical surface of sampling cutter 10 is shaped to the conical surface；Storage cutter is about 20
Slide and be arranged in sampling cutter 10；Cut-out closing cutter bag 30 includes a pair semicircular cutoff tools being symmetrical set
31；A pair of cutoff tools 31 symmetrical can be hidden on sampling cutter 10 and be provided with driver element and locking on cutoff tool 31
Unit；
As shown in Figure 1 to 4, cylinder groove 100 is formed on the upper surface of sampling cutter 10；The bottom of upper cylinder groove 100
The cylindrical lifting groove 101 for running through up and down is offered on face；The lifting of some arc-shapeds is offered on the side wall of lifting groove 101
Gathering sill；Storage cutter 20 is the annulus knife of opening down setting；Storage cutter is slided about 20 and is arranged in lifting groove 101 simultaneously
And formed on external cylindrical surface with sampling cutter 10 lifting gathering sill it is corresponding storage slide block 21；The lifting of sampling cutter 10
The left and right sides at the middle part of the side wall of groove 101 offers cutoff tool and hides groove；The straight line of a pair of cutoff tools 31 be shaped to cutting edge and
It is oppositely arranged；A pair of cutoff tools 31 are combined into complete circle；A pair of cutoff tools 31 can be slided and be hidden in sampling cutter 10
Cutoff tool hides the left and right sides of groove.
As shown in Figure 1 to 4, the cutoff tool of sampling cutter 10 to be hidden and offer the driving for extending upward through on the upper side wall of groove
Groove 102；Cut-out guide pad corresponding with the lifting gathering sill of sampling cutter 10 is formed on a pair of external cylindrical surfaces of cutoff tool 31；
The driver element of cutoff tool 31 is cylinder drive rod 32；Cylinder drive rod 32 be respectively and vertically fixed at a pair of cutoff tools 31 away from
Cut-out guide pad on and can slide sampling cutter 10 driver slot 102 in；The locking unit of cutoff tool 31 is locking screw
Female 33；The upper end of cylinder drive rod 32 forms screw thread；Locking nut 33 is screwed onto the upper end of cylinder drive rod 32；Storage cutter
The storage of 20 left and right sides is slided block 21 and offers the storage stopper slot 210 for running through up and down；Receive leaning on for stopper slot 210 a pair
Near side be shaped to the semi-cylindrical corresponding with cylinder drive rod 32, away from side open-ended.
As shown in Fig. 2 the external diameter of storage cutter 20 is identical with the diameter of cutoff tool 31.
As shown in Figure 2, Figure 4 shows, the hiding groove of the cutoff tool of sampling cutter 10 is symmetrical and is shaped to elongated hole-shape；Sampling knife
The cutoff tool of tool 10 hides the both sides diameter of groove and the diameter of the cut-out guide pad of cutoff tool 31 is identical.
As shown in Fig. 2 the lower end diameter of sampling cutter 10 is identical with the diameter of lifting groove 101, the upper of block 21 is slided in storage
End face is concordant with the upper surface of storage cutter 20, and the lower surface of the lower surface higher than storage cutter 20 of block 21 is slided in storage.
The principle of sampling cutter is as follows：
When needing to extract pedotheque, downward pressure is applied to sampling cutter 10, as sampling cutter 10 is downwardly into soil
Earth, also into storage cutter 20, sampling cutter 10 continues downwards, to receive cutter 20 and enter membership with adopting with soil soil
The lifting groove 101 of sample cutter 10 rises, and in the taper surface of sampling cutter 10 fully enters soil, storage cutter 20 reaches sampling
The highest point of the lifting groove 101 of cutter 10, is now hidden in a pair of cutoff tools 31 of sampling cutter 10 artificial or motor-driven
Advance to centre under effect, until a pair of cutoff tools 3 are mutually contradicted, now pedotheque lower end is cut off, cylinder drive rod 32
Enter into the storage stopper slot 210 that block 21 is slided in storage；Then locking nut 33 is screwed down, cutter 20 and a pair are so received
Cutoff tool 31 is connected, and pedotheque can be closed in storage cutter 20, and finally taking out storage cutter 20 can transport
.
Above content is only better embodiment of the invention, for one of ordinary skill in the art, according to the present invention
Thought, will change in specific embodiments and applications, this specification content should not be construed as to this hair
Bright limitation.
