A petrol drill for glacier drilling

Abstract

The invention relates to a gasoline drill for glacier drilling. The gasoline drill for glacier drilling is characterized in that a gasoline engine is connected with a variable speed gear, an annular handle is connected with a connecting board, the gasoline engine is fixedly connected with the variable speed gear through the connecting board, a variable speed controller is arranged on the annular handle and connected with the variable speed gear, a gasoline tank is located at the lower portion of the gasoline engine and is connected with the gasoline engine, the gasoline engine is provided with a cord switch, one end of a drill rod penetrates through the connecting board, a pin is plugged into a pin hole in the connection position of the drill rod and the variable speed gear for fastening at the joining position of the drill rod and the variable speed gear, the other end of the drill rod passes through a drill rod bayonet hole, a pin is plugged for fixing when a pin hole in the position, connected with a drill bit, of the drill rod and a pin hole in the position, connected with the drill rod, of the drill bit coincide, and a biconical blade is welded to the embedment port of the drill bit. The gasoline drill for glacier drilling is light and convenient to assemble and disassemble, gasoline serves as a power source of the drill, energy reduction of drills at the cold highland area is avoided, manpower and material resources are saved, and the gasoline drill for glacier drilling is suitable for ice and snow drilling of high cold and high altitude areas.

Description

technical field

[0001] The invention belongs to a high-efficiency and convenient gasoline glacier flower rod drill, is an instrument used in the layout of glacier material balance field observation operation points, and belongs to the field of machinery. Background technique

[0002] As an indicator of climate change, glaciers / ice sheets store 75% of the global freshwater resources. They are the focus of research on climate change and hydrology and water resources in arid areas, and have important scientific value and social significance. As the most basic physical quantity to describe the characteristics of glaciers and measure the changes of glaciers, the mass balance of glaciers is the key element linking the interaction of atmosphere-cryosphere-hydrosphere. The study of changes in material balance and its relationship with climate and hydrology has also become a hot topic in climate, ocean, cryosphere and other disciplines. One of the key scientific issues prioritized b...
