Description

Portable novel shallow water mud sampler

Technical Field

The utility model belongs to the field of mud extractors, and particularly relates to a portable novel shallow water mud extractor.

Background

When underwater geological exploration and underwater benthos collection research are carried out, underwater sediments are often required to be collected, and a shallow water mud sampler is a collection device for bottom mud and sludge of a shallow water body. Before doing projects on water, the water is generally subjected to ecological investigation, including investigation of the content of heavy metals in sediment and investigation of benthic organisms, so that sampling of bottom sediment and sediment is particularly important in the process of researching water ecosystem. The closing of most of the mud collectors is achieved by the weight of the mud collectors, so that the mud collectors are heavy, sampling personnel are inconvenient to operate, and sampling fails due to the fact that the grab buckets are not tightly closed.

Disclosure of Invention

In order to solve the problems, the utility model discloses a portable novel shallow water mud sampler.

In order to achieve the purpose, the technical scheme of the utility model is as follows: the utility model provides a portable novel shallow water mud sampler, includes the grab bucket of two relative settings, two top between the grab bucket rotates the bottom of connecting at a pull rod respectively, the pull rod is the screw rod, overlaps through the screw thread on this pull rod and is equipped with a threaded sleeve, threaded sleeve's bottom is rotated and is connected with the throw-out collar, both ends all rotate about the throw-out collar and are connected with a push rod that the downward sloping extends gradually, the upper end of grab bucket corresponds the push rod and leans out to extend an effect piece, the push rod with the effect piece rotates mutually and connects.

In the above scheme, the bottom end of the pull rod is sleeved with an elastic corrugated sleeve, the upper end of the elastic corrugated sleeve is hermetically connected with the threaded sleeve, and the lower end of the elastic corrugated sleeve is hermetically connected with the pull rod.

In the above scheme, the pull rod and the push rod are both hollow structures.

In the above scheme, a plurality of water drainage tank have all been seted up to the front and back both sides face of grab bucket, water drainage tank extends the setting along the horizontal direction, water drainage tank's opening is by the inner chamber of grab bucket outwards slope extension gradually.

In the scheme, the non-stick coating is uniformly coated on the wall of the inner cavity of the grab bucket.

In the above scheme, the top of the pull rod is connected with a pull ring.

The utility model has the beneficial effects that: according to the shallow water mud sampler, the pull rod is arranged between the two grab buckets, the pull rod is a screw rod, the pull rod is sleeved with the threaded sleeve through threads, the push rod is arranged between the threaded sleeve and the grab buckets, when the shallow water mud sampler is used, the pull rods on two sides of the shallow water mud sampler can be driven to push or pull the two grab buckets to be closed or opened to sample through rotating the threaded sleeve, the overall design is simple, the operation is convenient, the shallow water mud sampler is designed by adopting a pure mechanical method, and the shallow water mud sampler has the characteristics of high sampling efficiency, labor saving and the like.

Detailed Description

The present invention will be further illustrated with reference to the accompanying drawings and specific embodiments, which are to be understood as merely illustrative of the utility model and not as limiting the scope of the utility model.

Example (b): referring to fig. 1-3, a portable novel shallow water dredger comprises two grab buckets 100 which are arranged oppositely, the top end between the two grab buckets 100 is respectively and rotatably connected to the bottom end of a pull rod 200, the pull rod 200 is a screw rod, a threaded sleeve 201 is sleeved on the pull rod 200 through threads, the bottom of the threaded sleeve 201 is rotatably connected with a push ring 202, the left end and the right end of the push ring 202 are both rotatably connected with a push rod 203 which gradually inclines downwards and extends, an action block 204 extends outwards corresponding to the push rod 203 at the upper end of the grab bucket 100, the action block 204 is arranged close to the outer side of the grab bucket 100, and the push rod 203 is rotatably connected with the top end of the action block 204 through a pin shaft;

the threaded sleeve 201 and the pull rod 200 form a linear motion pair, in the using process, the threaded sleeve 201 is rotated downwards to push the push rods 203 on two sides of the push ring 202 to act on the action block 204, the action block 204 drives the two grab buckets 100 to be mutually closed to collect mud, otherwise, when the threaded sleeve 201 is rotated reversely, the bottom ends of the push rods 203 pull the outer ends of the two grab buckets 100 to be separated through the action block 204, and therefore the grab buckets 100 are opened.

In order to protect the space between the threaded sleeve 201 and the pull rod 200 and avoid the influence of impurities on the rotation of the threaded sleeve 201 and the pull rod 200 in the using process, the bottom end of the pull rod 200 is sleeved with an elastic corrugated sleeve 300, the upper end of the elastic corrugated sleeve 300 is hermetically connected with the threaded sleeve 201 through a hoop, the lower end of the elastic corrugated sleeve is hermetically connected with the hoop of the pull rod 200, and the elastic corrugated sleeve 300 can be a rubber corrugated pipe.

In order to reduce the weight of the pull rod 200 and the push rod 203, both have hollow structures.

The front side surface and the rear side surface of the grab bucket 100 are respectively provided with a plurality of water drainage grooves 101, the water drainage grooves 101 extend along the horizontal direction, the water drainage grooves 101 are communicated with the inner cavity of the grab bucket 100, the openings of the water drainage grooves 101 gradually extend outwards from the inner cavity of the grab bucket 100, during mud collection, more water sometimes enters the grab bucket 100, the integral weight of the grab bucket is increased, and the water drainage grooves 101 are arranged to discharge the excessive water during mud collection; meanwhile, the opening of the drainage channel 101 is gradually extended obliquely outwards from the inner cavity of the grab 100, so that the drainage channel has a certain blocking effect, and mud collected in the grab 100 cannot be easily discharged.

In the above scheme, the inner cavity wall of the grab 100 is uniformly coated with a non-stick coating, and the non-stick coating can adopt a teflon coating, has hydrophobic and oleophobic characteristics, and is convenient for cleaning.

In the above solution, the top of the pull rod 200 is connected with a pull ring 205, which is convenient for holding.

It should be noted that the above-mentioned contents only illustrate the technical idea of the present invention, and the protection scope of the present invention is not limited thereby, and it is obvious to those skilled in the art that several modifications and decorations can be made without departing from the principle of the present invention, and these modifications and decorations fall within the protection scope of the claims of the present invention.
