Mobile undisturbed soil sampling device

Abstract

The invention discloses a mobile undisturbed soil sampling device, which comprises a frame and a group consisting of a sampling rack, a bulldozing rack, a sampling component, and a gear which are connected to the frame, wherein the sampling rack and the bulldozing rack are slidably connected to the frame; the sampling rack and the bulldozing rack are meshed with both sides of the gear respectively; the gear is further connected to a gear driving device; the lower end of the bulldozing rack is connected to the sampling component; the sampling component comprises a sampling tube and a pluralityof ring cutters arranged side by side in the sampling tube; a cutter head is disposed on the lower end of the sampling tube; the sampling tube is detachably connected to the sampling rack; a threadedpipe connected to the frame is further disposed above the bulldozing rack; a bulldozing plate is disposed on the upper end of the bulldozing rack. When the soil is bulldozed, the threaded pipe is connected to the sampling tube, and the bulldozing plate is connected to the ring cutters. The soil overflowing state detection device of the invention can reduce the influence of soil compaction on a sample. The double racks can simultaneously perform sampling and soil cutting operations. Bracket tapered legs can be inserted into the soil to realize a positioning function.

Description

technical field [0001] The invention relates to the field of soil sampling devices, in particular to a mobile undisturbed soil sampling device. Background technique [0002] Soil quality in agricultural production plays a key role in the evaluation of agricultural production. The quality of soil requires the evaluation of physical indicators, chemical indicators, and biological indicators. To evaluate soil quality through these indicators, it is required that the soil samples taken meet the requirements of Sampling standards, among which the physical indicators of the soil have the highest requirements on the original state of the soil. If the soil samples taken can meet the determination of physical indicators, they can also meet the measurement of chemical indicators and biological indicators. In addition, the existing soil sampling mostly adopts the artificial ring knife hammering method, which is low in sampling efficiency and labor-intensive. Contents of the invention...
