Mine coil sampling repairing device

Abstract

The invention provides a mine coil sampling repairing device. The device comprises a main frame, brackets are symmetrically and fixedly welded at two ends of an external lower surface of the main frame; a mounting rod is fixedly welded at a lower end of each bracket; a rotating tube is rotatably arranged in a lower end of a first drill stem in a tubular type, second sampling slots are formed at afront sidewall and a back sidewall of the lower end, and first sampling slots are arranged at a left side and a right side of the lower end; a second drill stem is spirally and fixedly arranged at thelower end of the first drill stem through the thread; the second drill stem is arranged at the middle lower part in the main frame, and a third motor is fixedly arranged at the inner side of a sliding rod; a drill is rotatably connected with the outer surface of the lower end of the second drill stem and arranged above a sampling port; the sampling port is formed at the middle of the lower wall of the main frame. The repairing device disclosed by the invention is strong in flexibility, simple for use, conforming to various use conditions, and high in practicability.

Description

technical field [0001] The invention relates to technical equipment for restoration of mining areas, in particular to a soil sampling restoration device for mining areas. Background technique [0002] Mining will cause mining activities, especially open-pit mining, which seriously damages the soil structure of the hillside. In addition, the heavy pressure of large-scale mining equipment causes the ground to collapse and soil cracks to form. Nutrient elements in the soil also flow into gobs or depressions along with fissures and surface runoff, resulting in shortage of soil nutrients in many places and a decrease in soil bearing capacity, resulting in barren land and destruction of vegetation, eventually leading to the formation of large areas of artificial bare land in mining areas. Make soil and water move more easily, and soil erosion intensifies. Mine solid waste slag is washed and leached by rainwater, and its toxic and harmful components can easily infiltrate into the ...

Problems solved by technology

Moreover, due to underground mining, the stability of mountains and slopes is affected, resulting in frequent occurrence of ground subsidence, cracking, collapse and landslides, and the probability of debris flow increasing

[0003] With the rapid development of the mining industry, the mining area is getting bigger and bigger. For the sake of the ecological environment, it is imperative to restore the environment of the mining area, and the restoration of the land is the most important, but the area of ​​the mining area is very large. If artificial soil sampling is used It is bound to take a lot of time, and the sampling efficiency is still very low. Currently, the soil sampler on the market is only suitable for a small area and a small amount of soil. For large-scale land such as mining areas, it is urgent to develop a device that can sample a large number of samples with high sampling efficiency.
