Embodiment Construction

[0025] figure 1 It is a top view of the simple and simple marine sediment paleomagnetism research sampling device of the present invention, which device includes two identical bracket end plates 1, two identical steel plates 2 with scales, two identical blades 3, Slider 4, slider 5, two identical screw rods 6, two identical rocking handles 7, transparent glue bracket 8, two identical threaded through holes 9, threaded countersunk holes 10 and threaded countersunk holes 11. Wherein, the two bracket end plates 1 are connected by a scale steel plate 2, and the two ends of the two band steel plates 2 pass through the openings on the bracket end plate 1 respectively. Figure 5 , there is a threaded through hole vertical to the surface of the steel plate at the center of the inner surface of the above opening figure 1 , used for installing fixing screws, and the fixing screws fixedly connect the end plate of the bracket and the strip steel plate through the screw holes. The two b...

Abstract

A simple ocean sediment sample separating device for paleomagnetism research comprises support end plates (1), steel plates (2) with scales, blades, sliders (4 and 5), screw rods (6) and shaking handles (7), wherein the blades are mounted on the steel plates (2), a transparent adhesive tape support (8) is mounted on the slider (4), a thread counterbore is formed in the middle of the slider (4) and matched with one screw rod (6), a thread counterbore (11) is formed in the middle of the slider (5) and matched with the other screw rod (6), threaded through holes are formed in the middle of the support end plates (1) and matched with the screw rods (6), the shaking handles (7) are connected with the screw rods (6) through inside hexagonal bolts, any number of sample boxes (12) with openings on one surface can be clamped between two sliders, all that is required is to make the opening surfaces of the sample boxes to face downward and press the sample boxes into ocean sediments by uniform force for one time during sampling, and the sampling can be completed.

Description

Technical field [0001] The invention relates to a simple sampling device for marine sediment paleomagnetism research, which is especially suitable for marine sediment sample division for environmental magnetism and paleomagnetism research. Background technique [0002] The columnar core samples drilled from the seabed need to be divided into two half cylinders along the diameter, and then the seabed sediments are divided into samples and put into a cube sample box with a side length of 20mm to enter the magnetic parameters. Measurement. The seabed sediments used for paleomagnetic research are mainly silt, and its main component is clay. The sedimentation process is very slow and undergoes complex biological and chemical actions. Due to its very low deposition rate, the sedimentation process is affected by the geomagnetic field. Due to The geomagnetic poles are constantly drifting with time, and even reversed. The sediments at different times record the strength and directio...
