Embodiment

Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is carried out Clearly and completely describe, it is clear that described embodiment is only a part of embodiment of the utility model, rather than whole Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not under the premise of creative work is made The every other embodiment obtained, belongs to the scope of the utility model protection.

As shown in Figure 1, Figure 2 and Figure 3, the utility model provides a kind of technical scheme：A kind of engineering geologic investigation sampling dress Put, including column jacket 1, the top left and right sides of the column jacket 1 is hinged with first handle 2, and the bottom of the column jacket 1 is provided with sampling Pipe 3, and probe tube 3 is helical form, reduces penetration resistance, the quantity that increase soil sample retains in probe tube 3, the probe tube 3 Bottom integrally formed with drill bit 4, the outer surface of the drill bit 4 is provided with screw thread, and pressure when increase is broken ground saves manpower, institute The inner chamber for stating column jacket 1 is provided with inner prop 5, and column jacket 1 is run through on the top of inner prop 5, and the top left and right sides of the inner prop 5 is hinged with Second handle 6, flips up when idle and tightens up, save floor occupying area, and convenient storage, the bottom of the inner prop 5 is provided with baffle plate 7, The lower surface of the baffle plate 7 is provided with push rod 8, and push rod 8 is arranged in probe tube 3, between the first handle 2 and second handle 6 Provided with fastener 9, when preventing from entering soil horizon, inner prop 7 is pushed upwardly, and collects useless soil, the fastener 9 Including lock 901 and latch hook 902, the lock 901 is rotatably connected on the lateral wall of second handle 6, and the latch hook 902, which is fixed, to be connected It is connected on the 901 corresponding positions of lateral wall and lock of first handle 2.

Specifically, the push rod 8 is helical form, and probe tube 3 is identical with the anglec of rotation of push rod 8, makes push rod 8 can be with Smooth moves in probe tube 3.

Specifically, the side wall that the side wall and second handle 6 and inner prop 5 of first handle 2 and column jacket 1 contact are contacted Buffer layer 10 is pasted with, multiple folding is prevented, caused to handle or inner prop 7, the damage of the contact portion of column jacket 1.

Specifically, the side wall of the column jacket 1 is provided with altitude scale table 11, and make operating personnel's clear and definite knows decline Position.

Specifically, the hinged place is elastic hinge, and elastic hinge can have the function of tightening up, and make handle in receipts Position when tight is fixed.

Specifically, the upper surface of the first handle 2 and second handle 6 is all provided with fluted, and is pasted with groove anti- Skidding 12, groove is hand-held place, and force is convenient, when slipmat 12 prevents field operation, has water on handle, increases hand and handle Frictional force between branch.

Operation principle：Before use, be first turned over downwards first handle 2 and second handle 6, then lock 901 is stuck in On latch hook 902, the position of fixed inner prop 5 and column jacket 1 prevents inner prop 5 from moving up drive push rod 8 during sinking and moving up, prevented Only probe tube 3 just acquires soil sample before precalculated position is reached inside it, and when probe tube 3 drops to precalculated position, solution is unlocked Button 901, inner prop 5 is twitched upwards, column jacket 1 is rotated, probe tube 3 is gathered soil sample, utilizes the viscosity and spiral helicine knot of soil Structure, makes soil sample be retained in probe tube 3, completes after sampling, the utility model is extracted out, rotating down pressing inner prop 5, drives push rod 8 Move down, the soil sample in probe tube 3 is released, complete sampling work.

While there has been shown and described that embodiment of the present utility model, for the ordinary skill in the art, It is appreciated that these embodiments can be carried out in the case where not departing from principle of the present utility model and spirit a variety of changes, repaiies Change, replace and modification, scope of the present utility model is defined by the appended claims and the equivalents thereof.
