The utility model has the beneficial effects of: two dentate structure devices formed the interlock structure when grab bucket was closed, can not blocked by the cobble when having ensured the bottom sampler sampling, the effectual work efficiency who improves the sampling of river lake benthos.
Description
Technical field
The utility model relates to a kind of grab bucket-type dredger, is specifically related to a kind of modified grab bucket-type dredger, belongs to mechanical field.
Background technology
In recent years, in water conservancy scientific research, the benthic community structure characteristics of research river lake bottom is often needed, so need to sample the bottom-dwelling in the lakebed matter of river.
Grab bucket-type dredger conventional at present, in Muddy Bottoms Lentic environment, can be good at sampling work, but when sampling in the lake, river of cobble substrate, usually because cobble blocks grab bucket mouth, causes sampling not complete smoothly.
Utility model content
For solving the deficiencies in the prior art, the purpose of this utility model is to provide a kind of modified grab bucket-type dredger, and this bottom sampler can be guaranteed can not be stuck in sampling process, thus can improve the work efficiency of sampling.
In order to realize above-mentioned target, the utility model adopts following technical scheme:
A kind of modified grab bucket-type dredger, comprising: grab bucket (1), assister bar (2) and pull bar (3),
Aforementioned grab bucket (1) is made up of the first grab bucket portion (101) and the second grab bucket portion (102), and the upper end of the two, for being flexibly connected, can being opened around connecting portion or close after connection;
Aforementioned assister bar (2) is made up of the first assister bar (201) and the second assister bar (202), the two top be flexibly connected, lower end is connected with the movable upper end in the first grab bucket portion (101) and the second grab bucket portion (102) respectively;
Aforementioned pull bar (3) is flexibly connected with the first grab bucket portion (101) or the second grab bucket portion (102);
It is characterized in that, also comprise: two dentalation devices (4),
Aforementioned dentalation device (4) is separately positioned on the edge of the bottom in aforementioned first grab bucket portion (101) and the second grab bucket portion (102), and when grab bucket (1) is closed, two dentalation devices (4) form occlusion structure.
Aforesaid modified grab bucket-type dredger, is characterized in that, aforementioned dentalation device (4) is tooth bar.
Aforesaid modified grab bucket-type dredger, is characterized in that, aforementioned rack is welded on the edge of the bottom in aforementioned first grab bucket portion (101) and the second grab bucket portion (102).
Usefulness of the present utility model is:
(1) when grab bucket is closed, two dentalation devices form occlusion structures, can not be blocked when ensure that bottom sampler is sampled by cobble, effectively raise river lakebed and to dwell the work efficiency of biological sampling;
(2) tooth bar selected by dentalation device, and structure is simple, easily manufactures.
Accompanying drawing explanation
Fig. 1 is the front view of grab bucket-type dredger of the present utility model;
Fig. 2 is the vertical view of the grab bucket-type dredger in Fig. 1;
Fig. 3 is the side view of the grab bucket-type dredger in Fig. 1;
Fig. 4 is the upward view of the grab bucket-type dredger in Fig. 1.
The implication of Reference numeral: 1-grab bucket, 2-assister bar, 3-pull bar, 4-dentalation device, 101-first grab bucket portion, 102-second grab bucket portion, 201-first assister bar, 202-second assister bar in figure.
Embodiment
Below in conjunction with the drawings and specific embodiments, concrete introduction is done to the utility model.
Referring to figs. 1 through Fig. 4, modified grab bucket-type dredger of the present utility model comprises: grab bucket 1, assister bar 2, pull bar 3 and dentalation device 4, wherein, grab bucket 1 is made up of the first grab bucket portion 101 and the second grab bucket portion 102, the upper end of the two, for being flexibly connected, can being opened around connecting portion or close after connection; Assister bar 2 is made up of the first assister bar 201 and the second assister bar 202, the two top be flexibly connected, lower end is connected with the movable upper end in the first grab bucket portion 101 and the second grab bucket portion 102 respectively; Pull bar 3 is flexibly connected with the first grab bucket portion 101 or the second grab bucket portion 102; Dentalation device 4 has two, be separately positioned on the edge of the bottom in the first grab bucket portion 101 and the second grab bucket portion 102, when grab bucket 1 is closed, two dentalation devices 4 form occlusion structure, thus can not be blocked by cobble when ensure that bottom sampler is sampled, and then effectively raise river lakebed and to dwell the work efficiency of biological sampling.
As the preferred scheme of one, dentalation device 4 is tooth bar, and rack structure is simple, easily manufactures.
More preferably, rack welding is in the edge of the bottom in the first grab bucket portion 101 and the second grab bucket portion 102, and the connected mode of welding is more solid and reliable.
It should be noted that, above-described embodiment does not limit the utility model in any form, the technical scheme that the mode that all employings are equal to replacement or equivalent transformation obtains, and all drops in protection domain of the present utility model.
