Large undisturbed-soil sampling equipment
2011
The utility model relates to large undisturbed-soil sampling equipment, which comprises a soil-sample fixer, a knife-surface separating soleplate, a locker, a gradient bracket and a hydraulic propeller, wherein the circumference of the soil-sample fixer is closed, the upper surface and the lower surface of the soil-sample fixer are open, a track on the soil-sample fixer is buckled with a channel slot on the knife-surface separating soleplate, a sleeve hook is arranged on the knife-surface separating soleplate, the locker is sleeved at the outer side of the soil-sample fixer from top to bottom, the gradient bracket is connected with the locker, the hydraulic propeller is placed on the gradient bracket, the sleeve hook of the knife-surface separating soleplate is hooked at one end of the hydraulic propeller, the other end of the hydraulic propeller is leaned against a movable supporting rod, and ring buckles are installed at the four corners above the soil-sample fixer. Through the large undisturbed-soil sampling equipment, the original levels of soil can be better preserved, and the sampling authenticity is ensured; the collecting quantity is large, a large-volume undisturbed-soil sample can be collected, and the requirements of scientific researches are met; and meanwhile, because the hydraulic propeller is utilized as a power during sampling, the labor is saved, and the work efficiency is improved.
