Firmly, the shocking damage to lucite tube is reduced)；The periphery of rubber sleeve 9 use stainless steel material pipe clamp anchor ear 8, realize with
The fixation and sealing of lucite tube 1.The other side of rubber sleeve 9 is internally provided with internal screw thread, the outer spiral shell with 4 lower end of stainless steel tube
Line together, realizes being fixedly connected for engagement thread.The top of stainless steel tube 4 is socketed with hammering handle 11, and hammering handle 11 is not
Rust steel material.The handle be it is detachable, when injection sampling, the vertical injection bed mud of sampler can be made by hammering the component,
More save strength.Piston rod 7 is socketed in stainless steel tube 4, one end of piston rod 7 connects piston handle 6, the other end of piston rod 7
It is socketed with double-layer structure piston, is rubber leather plug 3, hole piston 2 respectively.As shown in Fig. 2, the upper end of rubber leather plug 3 and with holes
The lower end position of piston 2 is respectively provided with nut 12；The centre of rubber leather plug 3 and hole piston 2 is provided with metal gasket 13, realizes
Rubber leather plug 3, hole piston 2 vertical position fixation；Perforative through-hole 10 is provided on hole piston 2.
As shown in Figure 1, the pipe clamp anchor ear 8 with rubber sleeve 9 and use stainless steel material is sealed fixed
Extraction element is inserted in above lucite tube 1, and 1 lower end of lucite tube is provided with replaceable serrated edge formula sampling head 5.
As shown in figure 3, including the sampling head of big serrated edge formula and the sampling head of spiculation knive-edge.Sampling head 5 and organic glass
Glass pipe 1 is connected using thread forms, can be replaced according to the case where bed mud, can when such as the softer bed mud of progress quality samples
Close spiculation knive-edge sampling head is arranged using circumferential direction；Such as carry out quality it is harder bed mud sampling when, using circumferential direction arrange
Arrange sparse big serrated edge formula sampling head.
1 top of lucite tube is equipped with through-hole 10, and effect is that will have inside lucite tube 1 in sampling
A small amount of air and water discharge.Scale mark is indicated on the lucite tube 1, sampling can be measured by the scale
The depth of bed mud.
Such as Fig. 2, Double decker piston structure is set, and rubber leather plug 3, hole piston 2 are successively inserted in 7 lower part of piston rod.Upper layer is
The circle of high resiliency of the diameter slightly larger than 1 internal diameter of lucite tube (such as larger than 1 1~2mm of internal diameter of lucite tube), high durability degree
Rubber leather plug 3.For material, relatively hard, diameter is slightly less than 1 internal diameter of lucite tube (such as less than 1 internal diameter of lucite tube for lower layer
0.5~1mm) resin hole piston 2.
By above-mentioned text and figure, it can be seen that, the sampler of the utility model is a kind of removably taking for multisection type
