Soil survey sample sampling device

The utility model discloses a sampling device for a soil survey sample. The sampling device comprises a drill rod, a drill bit, a handle, a sampling core rod, a baffle assembly and a rotary positioning assembly, according to the utility model, through the baffle assembly, soil at a non-set sampling position can be effectively prevented from entering the sample storage cavity in the drilling process of the drill rod, and through the sampling core rod, the soil can be independently taken out after the sampling action is completed; the phenomenon that soil located on the upper layer of the set sampling position is brought into the sample storage cavity when the drill rod is directly screwed out of the soil is avoided, the accuracy of subsequent measurement results is guaranteed, and it can be effectively guaranteed that the drill rod is stable enough in the rotary drilling process through the arranged rotary positioning assembly. 本实用新型公开了一种土壤调查样品采样装置，包括：钻杆、钻头、手柄、取样芯杆、挡板组件，旋转定位组件。本实用新型通过设置的挡板组件，能够有效地防止在钻杆钻入过程中非设定
