Ice core treatment cutting device

Abstract

The invention relates to an ice core treatment cutting device. V-shaped groove bases are vertically fixed on a substrate at the bottom. Two V-shaped grooves are respectively erected and fixed on the two V-shaped groove bases at the bottom. A gap between the two V-shaped grooves and the two V-shaped groove bases at the bottom is a cutting seam for ice core cutting. The lower part of the cutting seam aligns at the upper part of the substrate. The upper edges of the two sides of the V-shaped grooves are used as scaleplates. Back parts of two sides of the two independent V-shaped grooves are respectively provided with LED board lamps. A disc cutting machine is fixed to one side of the V-shaped grooves. A cutting sheet is located above the cutting seam. An ice core is arranged in the V-shaped grooves. The device has a reasonable design and a compact structure, can accurately describe the physical parameters of the ice core during the pretreatment and accurately and vertically cut the ice core along a radial direction, effectively solves the problem of the easy dislocation of the ice core in the radial cutting and achieves the accuracy of ice core dating and high-resolution ice core recording and research.

Description

technical field [0001] The invention relates to an ice core processing and cutting device, in particular to a device that facilitates observation, description and radial vertical cutting of the ice core when the ice core is pretreated and sampled. Background technique [0002] Due to its high fidelity, high resolution, large amount of information and long time scale, ice cores can record information on climate and environmental changes in different historical periods. When the ice core is drilled in the field, the physical parameters (such as direction, length) and physical information (such as the type of granular snow, atmospheric dust deposits, volcanic eruption deposits, the size and shape and plant samples, etc.) for preliminary observations. Due to the extremely harsh field conditions of ice core drilling, tight working hours, and lack of good lighting facilities, it is impossible to carefully observe and describe the physical information contained in ice cores, and i...

Problems solved by technology

Since the ice core is a cylinder, when the length of the ice core is long and not fixed, coupled with the impact of the swing of the band saw blade in the horizontal direction on the ice core, the ice core cannot guarantee the same forward direction during the cutting process. The ice core cannot be accurately cut according to the sub-sample cutting line. If the cutting line is inclined, it will cause the overlap and dislocation of the recorded information of the two ice core samples before and after, which cannot meet the needs of high-resolution ice core record research.

In addition, during the cutting process, due to the smaller size, lighter weight and increased number of ice cores, it is easy to turn, shift, misplace and slip on the surface of the workbench when the staff accidentally touches them. On the one hand, it may cause ice The broken and lost ice cores will cause the loss of ice core records; on the other hand, it will also lead to the reversal of the order of the ice cores, resulting in the dislocation of the age of the ice cores, which will ultimately affect the accuracy of dating
