Core slot for core box

Abstract

The invention discloses a core slot for a core box, and relates to the field of a geographic exploitation vessel tool. The core slot comprises a bottom groove and a cover groove, wherein the lower part of the bottom groove is used for holding a rock core, a notch of the bottom groove faces upwards, the upper part of the cover groove is closed, a notch of the cover groove faces downwards, the bottom groove and the cover groove are formed by at least one square funnel-shaped groove with the circumferential groove wall retracted inwards, and a plurality of liquid discharging holes are formed in the bottom of the bottom groove and the top of the cover groove. The core slot for the core box is simple in structure and easy to realize, the interchangeability of components can be effectively improved, and the load resistance can be improved.

Description

technical field [0001] The invention relates to the field of geological exploration container tools, in particular to a core tank for a core box. Background technique [0002] With the progress and development of human civilization, industry, technology and engineering construction, the exploration and exploration activities of mineral geology, hydrogeology, engineering geology, scientific geology, etc. are becoming more and more extensive. In various geological surveys and exploration activities, drilling is mainly used to collect cores below the surface for reference and analysis of the original geological state to achieve the purpose of scientifically developing geological resources. Since a large number of cores will be produced during the drilling process, it is necessary to use a large number of core boxes to store, place or stack the cores sequentially, orderly and standardizedly to ensure that the cores can objectively represent the original geological state for geol...

AI Technical Summary

Problems solved by technology

[0003] But in the prior art, there are also the following problems: first, handmade core boxes, such as wooden core boxes, are mostly made by hand or semi-mechanically. The parts are fixed by iron nails, the production cannot be scaled, the cost is high, and due to the limitations of the material and processing technology of the wooden core box, it has poor structural performance stability, low load resistance strength, poor impact resistance, easy deformation, and easy loosening , flammable, perishable, bulky, bulky and other defects

[0004] Secondly, most of the plastic core boxes are rough in appearance, unreasonable in structure, small in support of the box, and not strong in the box. In actual use, due to the weight of the core and the complexity of the use, it is easy to cause damage to the box. The damage can hardly be repaired, the service life is short, and its large size, fear of high temperature and easy deformation are not conducive to storage, transportation and handling

[0005] Again, the strength of the PVC core groove is too low, the impact resistance is too poor, the placement is unstable, it is prone to fracture and overturning, the protection ability of the core is too poor and the handling difficulty

[0006]Finally, no matter the structure of wooden core box, plastic core box or PVC core tank is too simple, the weight it can carry is small, and it is easy to be deformed and damaged. The core protection ability of the core is weak, and careless operation may easily cause damage to the box during use and handling and collapse of stacked core boxes, destroying the original state of the core sample

The interchangeability of each part is poor. Once a part is damaged, it is almost impossible to repair the whole, and the recycling value after the whole is scrapped is also very low, and the relocation, transportation and storage of the core box of the whole structure are inconvenient
