The connection boom end connects wire drawing.
The beneficial effects of the present invention are: the present invention objects that will bear a heavy burden to be converted into dismountable card slot type insert, in card slot
The weight bearing object of embeddable various specifications can carry out different selections according to environment and the bed mud of required acquisition chromatography, protect
Demonstrate,prove the primitiveness of bed mud collected, there is hierarchy and representative, will not upset sample, mixing sample regardless of level,
It can guarantee that bed mud sample is not stirred as far as possible when the cutting bed mud of the bottom, improve the accuracy of later period assay, it is right
The bed mud chromatographic analysis chemical examination in later period has great significance.
Detailed description of the invention
Fig. 1 is main view of the present invention；
Fig. 2 is left view of the present invention；
Fig. 3 is top view of the present invention；
Fig. 4 is manual switch closed state schematic diagram.
Specific embodiment
For a better understanding of the present invention, with reference to the accompanying drawing, embodiment is described in detail.It should be understood that the present embodiment is only used
In illustrating the present invention, and cannot limit the scope of the invention.
Unless otherwise indicated, technological means used by the present embodiment is ordinary skill in the art means.
Referring to Fig. 1~4, the storage mud box 1 of bed mud acquisition device of the present invention is closed by two hollow a quarter cylindrical bodies to one
Play composition, each hollow a quarter cylindrical body it is relative to each other be not no side wall on one side, can just guarantee in this way
The two can form the storage mud box 1 an of hollow half cylinder when being combined together, be connected in middle upper portion by bearing 2, closure
When for half of cylindrical body structure, tell storage mud box 1 top be connected with connecting rod 8, it is described store up mud box 1 top be provided with partly
Automatic switch 3, the manual switch 3 include plug 4 and croze 5, and the top of the storage mud box 1 is provided with permeable hole 7, described
The left and right sides of storage mud box 1 is on the upper side to be provided with card slot 6, and 8 end of connecting rod connects wire drawing 9.
In above-mentioned each component, the bearing 2 is cylindrical structure, and setting connects two hollow four points on storage 1 top of mud box
One of cylindrical body, can make it is described storage mud box 1 two hollow a quarter cylindrical bodies rotated on certain Cheng Du；It is described semi-automatic
3 points of switch are the plug 4 and the croze 5, and the plug 4 and the croze 5 are separately positioned on two of the storage mud box 1
The left and right sides of a quarter cylindrical body, 4 shape of plug are rectangle, and rear end is arranged in one of the storage mud box 1
On empty a quarter cylindrical body (opposite with croze 5), it can be rotated upwardly and downwardly using 4 rear end set-point of plug as axle center, 4 front end of plug
There is a U-shaped opening, can mutually be linked with the inverted U-shaped hole of croze 5, when the U-shaped opening of plug 4 and the inverted U-shaped hole of croze 5 mutually link
When, make power that the storage mud box 1 can be made to be in open state upwards, the croze 5 is inverted U-shaped pore structure, is arranged in the storage mud
On another hollow a quarter cylindrical body of case 1 (opposite with plug 4), it can be connected with the U-shaped opening of plug 4, when croze 5
When inverted U-shaped hole and the U-shaped opening of plug 4 mutually link, power output can make the storage mud box 1 be in open state upwards；The card slot 6
The left and right sides of the storage mud box 1 position on the upper side is set, the weight bearing object of embeddable various specifications in slot；The permeable hole
7 are arranged in the top of storage mud box 1, extra water when to venting acquisition bed mud；8 lower end of connecting rod and storage 1 top of mud box
It is connected, upper end is connected with the wire drawing 9；The wire drawing 9 is passed through from described two 8 front ends of connecting rod, finally in the storage mud box 1
Connection is converged above center of gravity；It is described when the U-shaped opening of 4 front end of plug and the inverted U-shaped opening of the croze 5 mutually link
Two hollow a quarter cylindrical bodies for storing up mud box 1 pass through 2 rotating opening of bearing, when sinking under water, 4 front end of plug
U-shaped opening pulls the wire drawing 9 to move two connecting rods 8 inwardly because the inverted U-shaped opening of gravity and the croze 5 is fallen
It is dynamic, it drives the storage mud box 1 to rotate through the bearing 2, makes two hollow a quarter cylindrical body closures of the storage mud box 1.
When operation, two connecting rods 8 are rotated down first, make described two connecting rods 8 close to horizontal position, because of institute
It states two connecting rods 8 to be directly connected with two hollow a quarter cylindrical body tops of the storage mud box 1, so described in the rotation
When connecting rod 8, two hollow a quarter cylindrical bodies of the storage mud box 1 are rotated through the bearing 2, beat the storage mud box
It opens；
Then, the U-shaped opening of 4 front end of plug is passed through to the inverted U-shaped hole of the croze 5, and by the U of 4 front end of plug
Shape is open mutually to be linked with the inverted U-shaped hole of the croze 5, as shown in figure 4, operator is needed to be lifted up the wire drawing 9 at this time, because
The wire drawing 9 is directly connected with the front end of the connecting rod 8, and when proposing the wire drawing 9,8 both ends of connecting rod are turned upwards
Dynamic power can make two hollow a quarter cylindrical bodies of the storage mud box 1 by the bearing 2 rotation closure, but because described
The U-shaped opening of 4 front end of plug and the inverted U-shaped hole of the croze 5 mutually link, and make two hollow a quarters of the storage mud box 1
Cylindrical body can not be rotated by the bearing 2, and the connecting rod 8 can not be rotated up, and then the storage mud box 1 is in openning shape
State；
Subsequently, it is embedded in the weight bearing for being suitble to specification at the card slot 6, bed mud acquisition device is sunk under water, after sinking under water,
Under the action of gravity, the U-shaped opening of the plug 4 is fallen from the inverted U-shaped pore structure of croze 5, is fallen in the storage mud box 1 and is arranged
On the hollow a quarter cylindrical body of the croze 5；
Finally, the wire drawing 9 is pulled to be rotated up the connecting rod 8, the U-shaped hole of the front end of the plug 4 from the croze 5
In skid off, for two hollow a quarter cylindrical bodies of the storage mud box 1 by the bearing 2 rotation closure, bed mud sample adopts product
It will not reveal.When bed mud acquisition device pulls out the water surface, the water in the storage mud box 1 is from described in the top of the storage mud box 1
Permeable hole 7 is discharged.
Finally, the bed mud in the storage mud box 1 is carefully taken out, avoid disturbing brokenly the longitudinal distribution of ring bed mud and layer
It is secondary.
Bed mud acquisition device is cleaned after the completion of sample acquisition, and takes out weight bearing object and keeps, i.e., entire bed mud is adopted
Collection process is completed.
