Abstract

The invention relates to an automatic layered sludge collection device which comprises a sampling base plate, wherein a T-shaped device handle is fixedly arranged on the upper surface of the sampling base plate; a group of centrosymmetric spiral sleeve bases are fixedly arranged on the lower surface of the sampling base plate; hollow sludge collection pipes are spirally connected below the spiral sleeve bases; each sludge collection pipe consists of a plurality of sludge collection pipe units which are spirally connected with one another end to end; two semicircular backflow-prevention stop sheet are arranged in the bottom end of each sludge collection pipe unit. The automatic layered sludge collection device is simple in structure and convenient to operate and can simultaneously collect a plurality of samples and store the original thicknesses and the layered structures of deposits; the sampling base plate and the sludge collection pipes can be freely mounted and dismounted; the automatic layered sludge collection device is convenient and easy to use and can be replaced and cleaned quickly; the production cost is saved.

Description

A kind of AUTOMATIC ZONING dredger

Technical field

The invention belongs to and adopt mud technical field, be specifically related to a kind of AUTOMATIC ZONING dredger.

Background technology

In the aquatic ecosystem researchs such as marine ecology, fresh water ecology, water body deposit sample collection is the important content of sediment investigation at present, is also the important foundation of sediment analysis research.Therefore need some equipment for Sediment environment, to carry out Sampling Survey specially.For the layering collection of different water depth sediment sample, the domestic approved product that not yet has a kind of applied range, function-stable, some sediment collecting devices of current domestic use often can mix the sediment of each layer, do not reach the object of layering; Also have some sediment collecting devices to need artificial manually layering, not only efficiency is lower but also waste is serious.Therefore be badly in need of a kind of stable, efficient, portable, AUTOMATIC ZONING dredger that can reuse.

Summary of the invention

The object of the invention is for the deficiencies in the prior art, and propose a kind of AUTOMATIC ZONING dredger.

The present invention solves its technical matters and takes following technical scheme to realize:

A kind of AUTOMATIC ZONING dredger, comprise sampling pedestal disk, upper surface at sampling pedestal disk is fixed with T shape device handle, at sampling pedestal disk lower surface, be fixed with the screw sheel pedestal of a group switching centre symmetry, what below described each screw sheel pedestal, be all connected with hollow adopts mud pipe, adopt mud pipe by a plurality of mud pipe unit formations that spin from beginning to end of adopting for described every, the inside, bottom of adopting mud pipe unit at each is all provided with two anti-down flow resistance sheets of semicircle.

And, described in adopt whole disk size that two semicircle form drag sheets of mud pipe unit bottom form and adopt mud pipe unit internal diameter and mate, the circular arc top of described each semicircle form drag sheet is twisted to be contained in by twisted axis and is adopted on mud pipe unit inwall.

And, at the openend of described semicircle form drag sheet and adopt between the madial wall of mud pipe unit and be fixed with the spring that oblique upper stretches.

And the quantity of described one group of screw sheel pedestal is five, five screw sheel pedestals can correspondingly be installed five and adopt mud pipe, adopt mud Guan Youliu for every and adopt mud pipe unit formation.

And, described in adopt mud pipe unit diameter be between 10cm to 15cm, adopt the height of mud pipe unit between 70cm to 100cm.

Advantage of the present invention and good effect are

1, Stability Analysis of Structures of the present invention, easy to operate, when can carry out a plurality of sample, gathers.

2, structure of the present invention can be preserved sedimental original thickness and hierarchy.

3, holder of the present invention and adopt mud pipe and can freely mount and dismount, uses simple and convenient.

4, the mud pipe of adopting of the present invention can freely be dismantled and can change rapidly cleaning, has saved production cost.

5, the mud bobbin of adopting of the present invention is designed to six for the situation of current China Adjacent Sea mud and adopts mud pipe unit and form, the diameter of adopting mud pipe unit is between 10cm to 15cm, adopt the height of mud pipe unit between 70cm to 100cm, this structure not only can adapt to hardness, density, the viscosity of China's Adjacent Sea mud, effectively insert and get mud, and be particularly suitable for the layering situation of China's Adjacent Sea mud, more favourable for mud content analysis.

6, simple in structure, the diverse in function of the present invention, low cost of manufacture, marketable value high, be easy to promote.

Accompanying drawing explanation

Fig. 2 is the spatial structure enlarged diagram of adopting mud pipe unit in the present invention.

Embodiment

Below in conjunction with accompanying drawing, the invention process is further described, following examples are descriptive, are not determinate, can not limit protection scope of the present invention with this.

A kind of AUTOMATIC ZONING dredger, as shown in Fig. 1 or 2, comprise sampling pedestal disk 2, upper surface at sampling pedestal disk is fixed with T shape device handle 1, at sampling pedestal disk lower surface, be fixed with the screw sheel pedestal 3 of a group switching centre symmetry, what below described each screw sheel pedestal, be all connected with hollow adopts mud pipe 4, adopts mud pipe by a plurality of mud pipe unit 5 head and the tail formations that spin of adopting for described every, and the inside, bottom of adopting mud pipe unit at each is all provided with two anti-down flow resistance sheets 6 of semicircle.

In specific embodiment of the invention, as shown in Figure 2, the whole disk size that described two semicircle form drag sheets adopting mud pipe unit bottom form with adopt mud pipe unit internal diameter and mate, when two semicircle form drag sheet horizontal closed, will adopt mud pipe unit bottom closes, form bottom enclosed shape drum, the circular arc top of described each semicircle form drag sheet is contained in and is adopted on mud pipe unit inwall by twisted axis 9 strands, twisted axis aperture upwards, not-go-end is that semicircle form drag sheet drops to horizontal level, when gathering mud, two semicircular form drag sheet is pushed open open position by mud, when upwards mentioning while adopting mud pipe unit, two semicircular form drag sheet will be closed under the Action of Gravity Field of mud, the mud gathering enters thus adopts mud pipe unit, can not skid off, by a plurality of, adopt mud pipe unit spins and form adopt mud pipe and the mud layering of collection will be kept to different adopting in mud pipe unit like this.

In specific embodiment of the invention, as shown in Figure 2, described each top outside and inner side, bottom of adopting mud pipe unit is all shaped with screw thread 7, adopt mud pipe unit and spin from beginning to end, and whole is adopted spinning of mud pipe and screw sheel pedestal so that a plurality of.
