Abstract
The utility model designs a hard layer anchor sampler, which comprises a sampling tube, a sampling claw, a detachable piston and a release head; the sampling tube is a hollow sampling container, a plurality of sampling claws are arranged at the middle rear part of the sampling container, the bottoms of the sampling claws are communicated with the inside of the sampling tube, and a sharp opening is formed in the top part of the sampling claw along the direction of the sampling tube; the bottom of the sampling tube is provided with a release head which is communicated with all sampling claws, and the bottom of the release head is provided with a detachable piston which is used for ventilating and releasing the collected objects; the utility model discloses a hard layer sampler of shallow surface scrapes out harder silt top layer through sharp-pointed sampling claw, makes silt get into the sampling tube smoothly, and the sampling claw sets up a plurality ofly around the sampling tube, can accomplish the selection sample of different sampling claws through rotatory sampling tube. After the sample, wet soft silt can not bond on the inner wall of sampling tube basically, when needing the release sample thing, unscrew detachable piston can conveniently obtain, and sampling efficiency is high, convenient to use.
Description
Technical Field
The utility model relates to a sampling device technical field particularly, relates to a stereoplasm layer anchor formula sampler.
Background
In marine geological exploration and water conservancy scientific research, underwater sediments are often required to be sampled, and a mud sampler is generally used for sampling; the field sampling of silt is the basic work of silt analysis, and current silt sample thief mainly has gravity type, excavation formula etc. and the sample volume is big each time, is applicable to the soft earth that can provide big sampling depth.
In the prior art, a suitable sampling device is lacked for sampling of a harder sediment bed requiring shallow surface layer sampling. Most of the soil surface layer is hard, the prior silt sampler does not have the structural function design of pre-loosening silt to be sampled so as to facilitate subsequent sampling, and in addition, the obtained silt has high viscosity and is easy to adhere to the inner wall of the sampler, and the separation process is complicated.
SUMMERY OF THE UTILITY MODEL
In order to solve the above problem, the utility model provides a stereoplasm layer anchor formula sampler, its specific scheme as follows:
a hard layer anchor type sampler comprises a sampling tube, a sampling claw, a detachable piston and a release head;
the sampling tube is a hollow sampling container, a plurality of sampling claws are arranged at the middle rear part of the sampling container, the bottoms of the sampling claws are communicated with the inside of the sampling tube, and a sharp opening is formed in the top part of the sampling claw along the direction of the sampling tube;
the bottom of the sampling tube is provided with a release head which is communicated with all sampling claws, and the bottom of the release head is provided with a detachable piston which is used for ventilating and releasing the collected objects;
the inner wall of the sampling claw is pasted with an anti-adhesion layer, and the top of the sampling tube is provided with a connecting piece for connecting an external cable.
In a preferred embodiment, the opening of the sampling claw is an elliptical opening.
Furthermore, the sampling claw is provided with 4, and the bottom of 4 sampling claws is communicated with the same position of the sampling tube.
Further, the detachable piston is connected with the release head through threads.
Further, the anti-bonding layer is made of a water-permeable PE material.
The utility model has the advantages of that:
it is reasonable to have designed structural design, is applicable to the hard layer sampler of superficial layer of harder silt bed, scrapes hard silt top layer through sharp-pointed sampling claw, makes silt get into the sampling tube smoothly, and the sampling claw sets up a plurality ofly around the sampling tube, can accomplish the selection sample of different sampling claws through rotatory sampling tube. After sampling, the wet and soft silt can not be adhered to the inner wall of the sampling tube basically, and when a sample needs to be released, the detachable piston can be unscrewed to obtain the sampling tube conveniently. The sampling efficiency is high, the use is convenient, and the scientific research or user requirements in the field of marine geological exploration can be met.

Referring to fig. 1-2, a hard layer anchor sampler comprises a sampling tube 1, a sampling claw 2, a detachable piston 3 and a release head 4;
the sampling tube 1 is a hollow sampling container, a plurality of sampling claws 2 are arranged at the middle rear part of the sampling container, the bottoms of the sampling claws 2 are communicated with the inside of the sampling tube 1, and the top of the sampling claw 2 is provided with a sharp opening along the direction of the sampling tube 1; in a preferred scheme, the opening of sampling claw 2 is oval opening, sampling claw 2 is provided with 4 around sampling tube 1, and 4 sampling claws 2 bottom intercommunication in sampling tube 1 is in the same place. Scrape out harder silt top layer through sharp-pointed sampling claw, make silt get into the sampling tube smoothly, the sampling claw sets up a plurality ofly around the sampling tube, can accomplish the selection sample of different sampling claws through rotatory sampling tube.
The bottom of the sampling tube 1 is provided with a release head 4, the release head 4 is communicated with all sampling claws 2, the bottom of the release head 4 is provided with a detachable piston 3, the detachable piston 3 is connected with the release head 4 through threads, the size of a connecting gap between the piston 3 and the release head is adjusted through threads, and the sampling tube can be used for ventilation. After sampling is completed, the piston 3 is opened to release the collected material.
The inner wall of sampling claw 2 pastes and has covered the adhesion-preventing layer, adhesion-preventing layer preferably adopts the PE material that permeates water to make, the top of sampling tube 1 is equipped with the connecting piece for connect outside hawser, release the sampler.
Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
