Description

Technical Field

[0001] The utility model relates to the technical field of soil sample collection, in particular to a soil sample sampling device for environmental impact assessment detection. Background Technique

[0002] Environmental impact assessment is to analyze the rationality of the implementation of an enterprise's planned production and construction activities from the environmental aspect. Environmental assessment projects include water quality detection, air quality detection, noise detection, soil detection, and radiation detection.

[0003] Among them, soil detection is to detect pollutants such as heavy metals, organic matter, and radioactive substances in the soil. Through soil detection, we can understand the health status of the soil and provide a scientific basis for land planning and management.

[0004] When detecting various physical and chemical indexes of the soil, the detection results are not only related to the quality of the selected points, but also the soil sampling device has an inestimable impact on it. When sampling the surface soil, common sampling devices such as a core cutter or a small spade can be used. However, when sampling deeper soil, a soil drill is often used for sampling.

[0005] After the common soil sampling device finishes sampling, the soil sample is pushed out of the soil drill through its sample pushing rod to realize the collection of the soil sample. However, most soil drills take out the soil through the friction between the soil and the drill bit. When pushing out the soil sample with the push rod, it is necessary to overcome the friction between the soil and the drill bit. Therefore, it is easy to damage the natural structure of the soil sample due to overcoming the friction, making the soil sample possibly become a waste sample.

[0006] A soil sample collection device for environmental impact assessment of the utility model can take out the soil sample intact and then layer it, ensuring the natural structure of the soil sample and improving the accuracy of the detection results of the soil sample indexes. Content of the Utility Model

[0007] Aiming at the deficiencies of the prior art, the utility model provides a soil sample collection device for environmental impact assessment, which has the advantages of not destroying the natural structure of the soil, being convenient to take out the soil sample, and not relying solely on friction to prevent the soil from falling off.

[0008] To achieve the above object, the utility model is realized by the following technical solutions:

[0009] An earth sample sampling device for environmental impact assessment testing, comprising a support plate. Inside the support plate, multiple rotating rods are installed. At both ends of the multiple rotating rods, pressing handles are rotatably connected. Multiple fiber ropes are fixedly connected to the multiple rotating rods. A fixing rod is connected below the support plate. A soil sample collection bucket is fixedly connected below the fixing rod. An anti-collapse bucket is connected to the periphery of the soil sample collection bucket. At the lower end inside the anti-collapse bucket, multiple triangular fiber sheets are fixed. The other ends of the multiple fiber ropes are respectively fixedly connected to the tops of the multiple triangular fiber sheets. A rubber sheet covers the tops of the multiple triangular fiber sheets. One side of the multiple rubber sheets is fixedly connected to the bottom edge of the anti-collapse bucket.

[0010] Preferably, the fixing rod and the support plate are detachably connected by threads.

[0011] Preferably, pedal plates are fixedly connected to both sides of the periphery of the anti-collapse bucket.

[0012] Preferably, the soil sample collection bucket is closely attached to the inside of the anti-collapse bucket.

[0014] Preferably, the multiple fiber ropes are fixed together by a rubber sleeve, and the rubber sleeve is placed in the interlayer of the anti-collapse bucket.

[0015] Preferably, the top of the triangular fiber sheet is arc-shaped.

[0016] Preferably, scales are provided on the barrel body of the soil sample collection bucket.

[0017] Furthermore, the soil sample collection bucket is a transparent PC barrel.

[0018] Preferably, the soil sample collection bucket includes a left half and a right half, and the left half and the right half are connected by multiple hinge inner pieces.

[0019] Preferably, multiple first fasteners are connected to the left half, and multiple second fasteners are connected to the other side of the right half.

[0035] By setting the outer periphery of the soil sample collection barrel 6 to be closely attached to the inner side of the anti-collapse barrel 7, the two can move up and down together through friction.

[0036] In this application, a rubber sleeve 11 is wrapped around the outside of the plurality of fiber ropes 4, and the rubber sleeve 11 is placed in the sandwich layer 12 of the anti-collapse barrel 7.

[0037] By providing the rubber sleeve 11, the fiber ropes 4 can be better sorted out.

[0038] In this application, the tip of the triangular fiber sheet 9 is arc-shaped.

[0039] By setting the tip of the triangular fiber sheet 9 to be arc-shaped, when the fiber rope 4 contracts, the triangular fiber sheet 9 can more easily break away from the coverage of the rubber sheet 10 and thus tilt upward.

[0040] In this application, the soil sample collection barrel 6 is a transparent PC barrel, and scales are provided on the barrel body of the soil sample collection barrel 6.

[0041] In this application, the soil sample collection barrel 6 includes a left half part 6001 and a right half part 6002, and the left half part 6001 and the right half part 6002 are connected by a plurality of hinge pieces 6003.

After the collection is completed, press down the pressing handle 3, the fiber rope 4 drives the triangular fiber sheet 9 to rotate upward, preventing the soil sample from moving downward. Hold the support plate 1 with both hands and pull upward to pull out the soil sample collection barrel 6 and the anti-collapse barrel 7. After removing the detachable fixing rod 5, push downward to push the soil sample collection barrel 6 out of the anti-collapse barrel 7, and open the soil sample collection barrel 6, then the collected soil sample can be taken out relatively completely.
