The invention discloses a Luoyang shovel drill rod connecting structure for loess exploration and a Luoyang shovel device and method.The Luoyang shovel drill rod connecting structure is characterized in that a hollow body is arranged at the front end of the hollow body, a collision block and a groove are arranged at the front end of the hollow body, a hemispherical concave surface is arranged on the inner side of the collision block, a hemispherical buckle is arranged in the hemispherical concave surface, and the spherical surface of the hemispherical buckle is fixedly connected with a handle; the handle penetrates through the through hole groove and extends out of the hollow body, the middle of the handle is connected with one end of a spring, the other end of the spring is fixedly connected with the body, and the end away from the collision block is provided with a threaded connector. A drill rod provided with an automatic hook is pressed in relatively to be automatically connected with a lock catch, and when the drill rod is extracted, the drill rod can be quickly separated only by pulling a handle; the device has the advantages of being simple in structure, convenient to manufacture, low in cost, easy to operate and the like, the exploration work efficiency of a traditional Luoyang shovel in the loess area can be optimized, field work is facilitated, and the device is suitable for exploration work of dispersive engineering exploration projects such as electric transmission lines and new energy power generation in the loess area.
Description
technical field [0001] The invention belongs to the technical field of engineering geological survey, and in particular relates to a Luoyang shovel drill pipe connection structure for loess survey, a Luoyang shovel device and a method. Background technique [0002] The Luoyang shovel was invented by Li Yazi, a villager near Luoyang, Henan, China, in the early 20th century and gradually improved for later generations. Luoyang shovel is a symbol of Chinese archaeological drilling tools, and it is also widely used in geotechnical surveys in loess areas. It is a simple and convenient shallow soil survey method by distinguishing the soil structure, color and inclusions brought out by the shovel head. [0003] Due to its light and fast characteristics, Luoyang shovel is now widely used in engineering survey sites with poor working and traffic conditions such as power transmission projects and wind farms in loess areas. Because the current Luoyang shovel survey needs to lift the ...
