Abstract

The invention provides an undisturbed soil sampler. The undisturbed soil sampler comprises a vertical separator plate and two semicircular drilling pipes having an edge, a circle soil retaining plateis fixed at the bottom of the vertical separator plate, an internal diameter of the semicircular drilling pipes is greater than a diameter of the circle soil retaining plate by 1-3 mm, a first supporting seat and a second supporting seat are respectively arranged at two sides of the vertical separator plate, same semicircular grooves are respectively arranged on the first supporting seat and the second supporting seat close to one side of the vertical separator plate along a vertical direction, the semicircular groove is greater than the diameter of the circle soil retaining plate, the first supporting seat is welded with the vertical separator plate, and the vertical separator plate and the second supporting seat are cooperated with hooks through hanging slots, so that a groove which is concentric with the soil retaining plate is formed by two semicircular grooves. The undisturbed soil sampler uses cooperation of the semicircular drilling pipes having the edge and the soil retaining plate, a complete soil sample can be kept while sampling, the original soil sample after observation and testing is restored, and the destroy of the soil sampler on lawn is reduced.

Description

technical field [0001] The invention relates to the technical field of soil sampling, in particular to a soil sampler in its original state. Background technique [0002] Soil is the basis for the growth of turfgrass and the material basis for the survival and development of human beings. Soil testing is an important guarantee for the normal growth and production of lawns. To test lawn soil properties by collecting undisturbed soil, it is essential to collect undisturbed soil through a soil collector, and the efficiency of the soil collector directly affects the accuracy and effect of soil testing. [0003] A variety of soil collectors have been disclosed, and one of them is a hand-held soil collector, which includes a first handle, a sampling rod, a ring cutter drill bit, a soil pulling rod and a soil cleaning piston, wherein one end of the sampling rod is connected to the first handle, and the other end is connected to the first handle. Connected with a ring cutter drill...
