Problems solved by technology

The common gravity type ice chip cylinder is very inefficient in the process of salvaging the ice chips, and usually requires multiple rounds to salvage the ice chips
When drilling into the deep ice layer, this situation of salvaging ice chips many times will seriously affect the progress of the entire ice core drilling

Abstract

The invention discloses a polar region deep ice layer drilling ice scrap salvaging barrel with a continuous vibration function, and belongs to the field of deep ice layer drilling. The polar region deep ice layer drilling ice scrap salvaging barrel is composed of a rotary disc, an upper positioning sleeve, a lower positioning sleeve, a movement conversion disc and an ice scrap collecting barrel. The rotary disc is connected with an upper rotation mechanism through a fixing pin. The upper positioning sleeve and an upper outer pipe are integrally connected in a pipe thread form. A lower fixing sleeve and an upper fixing sleeve are connected through four radial screws. The lower fixing sleeve and the rotary disc are connected through a bearing. The movement conversion disc and the ice scrap collecting barrel are fixed through a nut. The upper rotation mechanism drives the rotary disc to rotate at a low speed, the slow rotation movement of the rotary disc is converted into slow up-down vibration through a movement conversion sliding way, and then the ice scrap collecting barrel is driven to vibrate with the low frequency so as to collect ice scraps in drilled holes. The polar region deep ice layer drilling ice scrap salvaging barrel is compact in structure, the ice scrap barrel ice scrap collecting efficiency can be improved to the maximum degree, accordingly, time is saved for deep ice layer drilling, and the ice core drilling efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of deep polar ice drilling, in particular to a polar deep ice drilling ice debris overshot with a continuous vibration function. Background technique [0002] Ice core samples not only contain information such as the age of the glacier and its formation process, but are also the only carrier to record the temperature and greenhouse gases of the corresponding age, thus opening up a new way to restore the paleoclimate and paleoenvironment, and the ice core is therefore known as the "Climate History Books". During the process of drilling ice cores, the amount of remaining ice debris in the drill hole is an important factor affecting the efficiency of ice core drilling. When drilling into the deep ice layer, it is necessary to salvage the remaining ice debris in the borehole every few drilling times. The common gravity type ice chip cylinder is very inefficient in the process of salvaging the ice chips, and us...
