Embodiment

For making the purpose of this utility model, technical scheme and advantage clearer, in the utility model embodiment, technical scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is the utility model part embodiment, rather than whole embodiment.Embodiment based in the utility model, those of ordinary skills are not making the every other embodiment obtaining under creative work prerequisite, all belong to the scope of the utility model protection.

Embodiment 1

Fig. 1 is the stereographic map of the utility model bed mud harvester, Fig. 2 is the partial enlarged drawing of Fig. 1, referring to Fig. 1 and Fig. 2, and the bed mud harvester that the present embodiment provides, comprise and adopt mud portion and connecting link 1, the lower end of described connecting link 1 with described in adopt mud portion upper end and be connected; The described mud portion of adopting comprises storage mud box 8, removable bottom 9, wire drawing 5, latch 6, cotter way 7, permeable hole 3 and spin bath 4;

The hollow rectangular box body structure that described storage mud box 8 is an end opening; Described wire drawing card 2 is arranged on described connecting link 1, on described wire drawing card 2, has wire drawing through hole; Described latch 6, cotter way 7 and removable bottom 9 are two groups, and two groups of latches 6, cotter way 7 and removable bottoms 9 are separately positioned on the both sides of described storage mud box 8 openends;

Two described removable bottom 9 one end are hinged with the open end edge of described storage mud box 8 respectively; Described cotter way 7 comprises guide groove and slot, and described guide groove is arranged on described storage mud box 8 outer walls and the position of close openend, and described slot 6 is arranged on described removable bottom 9 and the position of close hinged end;

Described spin bath 4 is arranged on the outer wall of described storage mud box 8, and described spin bath 4 comprises first branch's groove and second branch's groove, and described first branch's groove is obliquely extended to described cotter way 7 places, and described second branch's groove vertically arranges; The main line of described wire drawing 5 is located in the wire drawing through hole on described wire drawing card 2, described the first branch is located in described first branch's groove and is connected with two described latches 6, and described the second branch is located in interior two the described removable bottoms 9 of described second branch's groove with respect to the other end connection of hinged end;

When described latch 6 is located in described guide groove and slot, described storage mud box 8, perpendicular to the openend of described storage mud box 8, is opened described openend; When lifting described wire drawing 5, described the first branch drives described latch 6 to skid off from described slot, and described the second branch drives described removable bottom 9 to rotate simultaneously, by described openend sealing.When bed mud harvester being pulled out to the process of the water surface, the water permeable hole that portion offers from it 3 in storage mud box 8 is discharged.

Fig. 3 is the schematic diagram of the utility model connecting link, please refer to Fig. 3, and the connecting link 1 that the present embodiment provides is comprised of mobile jib 10 and wire drawing card 2; Mobile jib 10 two ends have screw thread, can as required, select the screwed connecting link in multistage two ends to connect piecemeal; If connect multistage connecting link, wire drawing card need to be set in the middle part of every section of connecting link, for fixedly wire drawing easily and effectively.In addition, can also on described connecting link, scale be set, the fording depth of the each harvester of detection that can be easily and effectively, realizes at the waters of same degree of depth collecting sample.

The principle of work of the utility model bed mud harvester:

First, latch is located in to guide groove and slot is fixed removable bottom, avoids the closed bed mud of removable bottom in cutting bed mud downwards cannot enter storage mud box; And according to gathering the bed mud waters degree of depth, specifically determine that the length of connecting link connects the connecting link of Len req piecemeal, and worn wire drawing at spin bath and wire drawing card, keep wire drawing to prepare stand-by in relaxed state;

Then, harvester is slowly put into water, until under removable bottom after end in contact bed mud, vertical direction is pressed this device, guaranteeing to store up mud box inside has bed mud to enter, and reaches the needed amount that detects.At harvester, place after stable and tighten up wire drawing, and wire drawing is wrapped in to bolt jail on the wire drawing card of a joint connecting link nearest apart from operator, to guarantee that the removable bottom of harvester lower end closes up, bed mud sample can not revealed.Again harvester is slowly pulled out to the water surface, the bed mud by storage in mud box carefully takes out, and avoids disturbance to destroy distribution and the level of bed mud on longitudinally.

Finally, after sample collection, harvester is cleaned, and unload lower connecting rod piecemeal, furled wire drawing, whole bed mud gatherer process completes.

The bed mud sample of harvester of the present utility model to each collection, can guarantee the primitiveness of sampling, can be as grab mechanisms regardless of upset sample, the biased sample of level.Whole device can guarantee as much as possible that bed mud is not uniformly mixed in bottom cutting bed mud, to later stage bed mud chromatographic analysis chemical examination important in inhibiting.

Finally it should be noted that: above embodiment only, in order to the technical solution of the utility model to be described, is not intended to limit; Although the utility model is had been described in detail with reference to previous embodiment, those of ordinary skill in the art is to be understood that: its technical scheme that still can record aforementioned each embodiment is modified, or part technical characterictic is wherein equal to replacement; And these modifications or replacement do not make the essence of appropriate technical solution depart from the spirit and scope of each embodiment technical scheme of the utility model.
