Abstract

The invention relates to a soil sampling device, which comprises a driving body and a drill tube arranged under the driving body, a drill bit is arranged at the end of the drill tube away from the driving body, three supporting legs are arranged at the bottom of the driving body, and the drill tube is divided into multiple The sampling cylinder and a plurality of supporting cylinders are arranged at intervals, the drilling cylinder is fixedly provided with a rotating shaft, the supporting cylinder is fixedly connected to the rotating shaft, the sampling cylinder is connected to the rotating shaft in rotation, the sampling cylinder and the supporting cylinder are fixed to each other through a fixing mechanism, and the sampling cylinder An auxiliary mechanism is provided to help the soil sample fall off. Different sampling cylinders represent soil samples of different depths. Rotate the sampling cylinder around the rotating shaft to leave the position of the support cylinder, and use the auxiliary mechanism to shed the soil inside the sampling cylinder to facilitate the sampling operation.

Description

technical field [0001] The invention relates to the technical field of soil samplers, in particular to a soil sampling device. Background technique [0002] Soil sample collection and analysis of its physical and chemical properties are widely used in construction engineering, environmental science, geography, agricultural production and other research fields. In addition to destructive excavation and sampling, the drill bit is usually inserted into the soil by rotating and pressing, and the friction between the drill bit and the soil is used. Soil samples with unearthed depth. [0003] Existing, disclose a kind of soil sampling soil taking device as Chinese patent utility model patent application announcement number CN208091748U, comprise main rod and drill bit, main rod overcoat is connected with outer tube, main rod lower end is provided with drill bit; Sawtooth, the inside of the drill bit end is provided with cross blades, and the end of the cross blades is provided wi...
