2) in light weight, focus on certainly about 5kg, satisfy the people requirement of sampling separately fully, can effectively increase work efficiency.
3) mud bucket and steelframe are " L " type structure, be formed with the angle of 70 degree～90 degree, by this structure, when collector touches sediment, sediment can be simplified sampling operation with in the collected mud bucket, and is simple to operate, save the step that struts and collect pole, can effectively improve sample collecting efficient.
In a word, the utility model can realize that a people finishes sampling operation alone, and is simple to operate, and greatly reduces the manufacturing and the maintenance cost of sampling thief, has good practical value and economic worth.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and Examples, in the accompanying drawing:
Fig. 1 is the synoptic diagram of surface deposit sampler under water of the present utility model;
Fig. 2 is the synoptic diagram of the mud bucket among Fig. 1.
Embodiment
As shown in Figure 1, surface deposit sampler under water of the present utility model comprises: fall cross 1, mud bucket 2, the described cross 1 that falls is fixedlyed connected with mud bucket 2, fixedly connected mode can be weld or securing member (for example: mode such as connection screw).See that from the side the cross 1 that falls is " L " type with mud bucket 2, is formed with angle each other, described angle is between 70 degree～90 degree, and in the present embodiment, the cross 1 that falls is 85 degree with spade bucket 2 and is provided with.
Specifically, described cross 1 is made the steelframe of falling the cross for adopting steel, comprise a pull bar 11 and a balance stem 12, described pull bar 11 vertically is provided with, described balance stem 12 horizontally sets, described balance stem 12 is near the lower end of described pull bar 11, and it is in the weight settings such as both sides of vertical pull bar 11, to keep balance.The upper end of described pull bar 11 is provided with a through hole 13, and described through hole 13 parallels with balance stem 12, and is linked with a draw ring 14 in through hole 13 draw rings, and the steel loop of described draw ring 14 for adopting steel to make is used to connect stay cord (not shown).
