The invention has the beneficial effects that: the sampler is slowly pressed into the lake bottom through the hydrostatic pressure of the oil cylinder of the excavator, and then the sampler is lifted out of the water surface through the hanging belt by the excavator. The creative simple method has the advantages of good practical application effect, quick sampling, high construction efficiency, large excavator pressure, continuous and stable pressure, deeper penetration depth, small disturbance to soil sample and high sampling integrity and quality; and the layered condition of the sludge can be observed more completely through the high-strength glass tube.
Drawings
FIG. 1 is a schematic structural view of the present invention;
FIG. 2 is a schematic view of a catch spring according to the present invention;
in the attached drawing, the sampler comprises a sampler cylinder 1, a sampler cylinder 2, a blocking spring 2-1, a cylinder 2-2, a spring piece 3, a high-strength glass tube 4, a connecting sleeve 5 and a drilling sleeve.
Detailed Description
The invention will be further described with reference to the following drawings and specific embodiments:
a river silt sampling device comprises a sampler cylinder 1, and is characterized in that the sampler cylinder 1 is split and is formed by buckling two semi-cylinders;
the bottom end of the sampler cylinder 1 is provided with a drilling sleeve 5, and the drilling sleeve 5 is in threaded connection with the bottom end of the sampler cylinder 1;
the drilling sleeve 5 is internally provided with a blocking spring 2 in interference fit, the blocking spring 2 comprises a cylinder 2-1 and at least two spring pieces 2-2, the spring pieces 2-2 are arranged at one end of the cylinder 2-1, the spring pieces 2-2 are distributed along the circumferential direction of the cylinder 2-1, the spring pieces 2-2 are bent towards the circle center, and one end of the blocking spring 2 with the spring pieces 2-2 faces the top end of the sampler cylinder 1.
In the concrete embodiment, as shown in fig. 1, a cylinder hydrostatic pressure of an excavator is connected with a connecting sleeve 4, a sampler cylinder 1 is slowly pressed into the lake bottom, a drilling sleeve 5 is firstly contacted with sludge and sinks downwards, air and water are discharged from the top end of the sampler cylinder 1 until the sampler cylinder 1 is completely immersed in the sludge, then the sampler cylinder 1 is lifted out of the water surface by the excavator through a hanging strip, and a spring piece 2-2 on a blocking spring 2 props against the sludge which is high in density and not easy to disperse at the bottom end of the sampler cylinder 1 due to elasticity until the sampler cylinder 1 is lifted out of the water surface and placed on the ground.
The sampler cylinder 1 is split, and after the sampler cylinder 1 is arranged on the ground, the sampler cylinder 1 can be directly opened to obtain a sludge sample.
As shown in fig. 1, a high-strength glass tube 3 is arranged in the sampler cylinder 1, and the high-strength glass tube 3 is sleeved with the sampler cylinder 1.
Because sampler drum 1 is split type, so sampler drum 1 opens the back, can directly see through high strength glass pipe 3 and observe the silt layering condition, makes things convenient for scientific research personnel to detect.
As shown in fig. 1, a connecting sleeve 4 is arranged at the top end of the sampler cylinder 1, and the connecting sleeve 4 is in threaded connection with the top end of the sampler cylinder 1.
Connecting sleeve 4 and 1 top threaded connection of sampler drum, connecting sleeve 4 can make sampler drum 1 and front end equipment be connected more convenient fastening.
As shown in fig. 1, the drilling sleeve 5 has a smaller bottom end opening than a top end opening.
The drilling sleeve 5 is in an inverted cone shape, so that sludge can be drilled more simply and smoothly.
