Description
Technical field
The utility model belongs to the technical field of bottom sampler, and in particular to a kind of gravity grab bucket bottom sampler.
Background technology
Grab bucket-type dredger is a kind of artificial sample of sludge in the cesspools such as a kind of artificial acquisition korneforos sludge and chemical industry
Tool is generally used in the business units such as environmental protection, health and epidemic prevention, tap water or chemical industry, is adopted for acquiring the artificial inconvenience such as deep, remote
The area for collecting sludge uses.This grab bucket-type dredger by symmetrical two-part arc as shown in Figure 1, mainly grabbed bucket 101 groups
At sampling grab bucket, machine driving executing agency composition, pass through and pull machine driving executing agency 103 to control sampling grab bucket to carry out
Mud captures, and then firmly lifting sampling grab bucket, sampling grab bucket is closed to adopt in river bed sludge by gravity block 102 and grab bucket into sampling
In.
But above-mentioned grab bucket-type dredger, has the following problems in actual use：
1. when entire mud acquires, when especially acquiring arenaceous sediment object, collected sample is easy to slip away, reason
It is, two parts semicircle grab bucket closure formation for sampling grab bucket seals the gravity block 102 for only relying on 101 outside of arc grab bucket
The component of gravity make arc grab bucket 101 two edges be close together, and this mode being close to be it is unsteady,
It is highly susceptible to the influence of wave or other lightweight physical impacts, sample is caused to fall to arc grab bucket 101 from the edge
Outside；
2. in the sinking of entire grab bucket-type dredger, two parts arc grab bucket 101 is used in a unfolded state
Sample mud is accommodated, more air is had in this way and enters inside arc grab bucket 101, in acquisition mud to closure two parts arc
During grab bucket 101, the sampling grab bucket inside that surplus air is trapped in sealing is had, is unfavorable for capturing mud sample.
Therefore, it is necessary to study a kind of new gravity grab bucket bottom sampler, to avoid lacking existing for traditional grab bucket-type dredger
It falls into.
Utility model content
Purpose of the utility model is to solve insecure, easy air entrapments of above-mentioned grab bucket-type dredger sealing etc. to ask
Topic provides a kind of gravity grab bucket bottom sampler.
In order to reach above-mentioned purpose of utility model, the utility model uses following technical scheme：
Gravity grab bucket bottom sampler, including it is symmetrically arranged it is left grab bucket and right grab bucket, it is described it is left grab bucket and right side grab bucket rotation
Connection, which is characterized in that the lower edge of the left grab bucket is equipped with the barb of one and lower edge rotation connection, and the lower edge of the right grab bucket is set
There are a fin to match with barb, the barb to be connect with one for controlling the drawstring of barb.
Further, the rotation connection of the barb and left grab bucket is specifically, the lower edge of left grab bucket is equipped with a torsional spring, the torsion
Spring both ends are contacted with lower edge, barb respectively.Under normality, torsional spring is uncompressed, and barb is fastened with fin so that left grab bucket, right grab bucket
In closed state；In capturing sample, drawstring is lifted so that barb is detached from fin, and torsional spring receives compression, and a left side is grabbed
Bucket, right grab bucket, which are opened, carries out sample crawl；After the completion of crawl, drawstring is unclamped, barb is fastened with fin again, left grab bucket, the right side
Grab bucket, which re-closes, avoids sample from being skidded off from the gap that left grab bucket, the right grab bucket of grab bucket are closed by external force.
Further, the barb shape is F shape structures, and the lower end of the F shapes structure is rotated with the left grab bucket lower edge
Connection, long side of the torsional spring both ends respectively with the outer wall of left grab bucket, F shape structures contact, the open side court of the F shapes structure
Upward；Or be n shape structures, one side of the n shapes structure is rotatablely connected with the left grab bucket lower edge, the torsional spring both ends point
An avris not with the outer wall of left grab bucket, n shape structures contacts, and the open side of the n shapes structure is upward.
Further, when the barb shape uses n shape structures, the n shapes structure is less than close to the side of right grab bucket side
The side of the close torsional spring side.
Further, the left grab bucket and/or the right tablet for grabbing bucket by a curved wall and being symmetrically set in curved wall both ends
Composition, curved wall and two tablets form an accommodating chamber, the curved wall upper end opening, and the accommodating chamber is located at opening lower section
Equipped with a liner net.It is arranged by being open so that during sinking to crawl mud sample, the air in accommodating chamber rises for grab bucket,
Accommodating chamber can be left by opening；And liner net is arranged while can realize ventilative to the opening direction on top, in turn ensures
The air-flow that mud sample will not be raised is slipped away from opening.
Further, the opening is to open up several through-holes in curved wall upper end.
Further, the hole area of the through-hole of the left grab bucket and/or right grab bucket is by far from left grab bucket and/or the right side
It is sequentially reduced in the lateral direction of grab bucket to left grab bucket, right grab bucket junction direction.Though if the size of through-hole is arranged to unanimously
So processing is simple, but be proximate to left grab bucket, the pore size too conference of right grab bucket junction forms local turbulence, be unfavorable for tiny type
The crawl of sample, the setting to form a gas channel from the outer side of left grab bucket or right grab bucket to the two junction, can drop
Low turbulent flow.
Further, the through-hole is at least semi-circular hole, square hole, three kinds of delthyrium, from left grab bucket or right grab bucket
Outside is grabbed bucket to the left, the junction of right grab bucket is set gradually.By setting gradually semi-circular hole, square hole, triangle from outside to inside
Hole forms stable gas channel, considerably reduces turbulent flow.
Further, the delthyrium be isosceles triangle, and towards it is left grab bucket, right grab bucket junction be apex angle.
Further, the diameter side of the semi-circular hole is provided close to the junction side of left grab bucket, right grab bucket.
Further, reclinate arcuated fin piece, the arcuated fin piece are from top to bottom equipped in the accommodating chamber successively
Outer end be blade-like sharp portion.Sample for being layered acquisition different levels, end set sharp portion facilitate insertion into silt
In mud.
Compared with prior art, advantageous effect is the utility model：
1. a gravity grab bucket bottom sampler realizes the compactness that the edge of grab bucket is bonded by barb with the cooperation of fin, carry
It high stability and resists wave or influence that other lightweight physical impacts are brought, effectively avoids the slave marginal flow of tiny sample
It loses；
2. avoiding the air in sinking watching in grab bucket accumulated inside, penetration resistance is reduced, ensures hopper inner space
Efficiently use, be conducive to crawl mud sample；
3. in turn avoiding being taken away by air-flow or flow for tiny mud sample while ensureing grab bucket interior air-flow outflow to cause to flow
It loses, and avoids the local turbulence caused by opening；
4. acquisition mud can be layered, the crawl effect to sample layer is improved, sample collection is effectively ensured；
5. it is simple in structure, it is easily installed dismounting, gatherer process is more laborsaving, and acquisition sample is more comprehensively reliable.
