Description
Technical field
The utility model is related to a kind of sample devices, more particularly to a kind of Wet-dry bottom sampler.
Background technology
Carrier of the deposit as all sediments in water body is constantly received from aquatic animal excreta, feeds feed
It residue, dead residuum and drains into the particulate matter in water.So deposit is an important mesh for studying aquatic environment
Mark.For huge sum of moneys such as lead, cadmium, mercury, arsenic of the shallow-layer to regions such as cultivating pool, river channel sedimentation objects loosely or in soft-sediment
Belong to, the chemical parameters such as sulfide and moisture content etc. are measured analysis, and people usually require by acquiring its vertical cylindrical sample
It is measured analysis.Currently, the bottom sampler of application mainly has grab bucket-type dredger and profile lead.General grab type adopts mud
Device when adopting mud, when grab bucket not completely disengaged control when, grab bucket can be difficult to be closed, and can cause to adopt the consequence of mud failure.Column is adopted
That there are weight is too heavy for mud device, and one man operation is not easy, and is also not easy to carry, and needs a check valve, casing to take out after taking mud, step
It is cumbersome, expend the time.
There are also some easy bottom samplers, bottom sampler front end is the tubulose sampling cylinder of front opening, rear end is handle,
It is connected by connecting rod between handle and sampling cylinder, sampling cylinder is sampled to eating sugared, river drift.If sampling cylinder is only
Front opening, when acquiring more dry deposit, the water and gas discharge in sampling cylinder are difficult, and sampling difficulty is big, and sample after sampling
This is difficult to take out, it usually needs slots in an axial direction in sampling cylinder side, is conducive to drainage exhaust and sample takes out；And acquire humidity
When larger deposit, due to deposit good fluidity, if the side wall of sampling cylinder opens up slot, deposit easily flows out.
Invention content
Utility model aims to solve existing grab bucket bottom sampler, profile lead are complicated complicated for operation,
And simple bottom sampler cannot be satisfied the problem of different sample requirements of dry mud and wet mud, provide a kind of Wet-dry bottom sampler.
Technical solution adopted by the utility model to solve its technical problems is：A kind of Wet-dry bottom sampler, bottom sampler
The sampling cylinder of front face open is arranged in front end, handle is arranged in rear end, connecting rod is arranged between sampling cylinder and handle, feature exists
In：Rear end inside the sampling cylinder is equipped with push plate that can be elastic, and the connecting rod is hollow stem, is arranged in connecting rod
It can slide back and forth and rotatable push rod, the front end of push rod be connected with push plate, the rear end of the push rod is pierced by handle and stretches out backward,
The aft bulkhead of the sampling cylinder be equipped with the first osculum, the push plate be equipped with can with push plate rotate be aligned with the first osculum or
Second osculum of dislocation.Push rod can be rotated and be slid back and forth.When sampling, push rod rotation drives push plate rotation, makes first row
Water hole and the alignment of the second osculum or dislocation, when sampling dry mud, the first osculum and the alignment of the second osculum make sampling cylinder
Rear end has the effect of drainage exhaust, and dry mud is facilitated to sample, and when sampling wet mud, the first osculum and the second osculum are wrong
Position, sampling cylinder back-end closure avoid wet mud from being leaked out from sampling cylinder front end.After the completion of sampling, it can make to push away by the sliding of push rod
Plate squeezes out sample from sampling cylinder.When first osculum and the second osculum misplace, although push plate is necessarily deposited with sampling cylinder rear wall
In gap, but the water and mud being mingled in gap can form the very poor water seal of mobility and mudding, form good sealing effect.
Preferably, mesh grille is arranged in the push plate at the second osculum.
Preferably, the putting back-end is equipped with lever, the lever and push rod are vertically connected and screw thread are used to connect
It connects.Lever can operate push rod and slide back and forth and rotate.
It is formed preferably, the front end face of the sampling cylinder is inclined-plane, sampling cylinder front end face and sampling cylinder side wall convenient for inserting
Enter the wedge angle in mud.
Preferably, the inner wall clearance fit of the push plate and sampling cylinder.
Preferably, first osculum is the slot hole of arc, the second osculum is circular hole.
The utility model is made the osculum in sampling cylinder rear wall and push plate be aligned or misplace, is enabled by the rotation of push plate
The open rearward end of sampling cylinder or closing can adapt to the sample requirement of dry mud and wet mud respectively；Push plate can be incited somebody to action with forward slip
Sample is released, convenient that sample is taken out from sampling cylinder.
