Sample collector for soil testing

The utility model discloses a sample collector for soil testing, which comprises a sampling barrel with a zigzag lower surface, and an outer sleeve attached to the upper surface of the sampling barrel is arranged on the upper surface of the sampling barrel; the driving motor is fixedly installed at the top end of the outer sleeve, and the left side and the right side of the driving motor are fixedly provided with hand-held handles used for holding the whole device; and the auxiliary pedal is mounted outside the outer sleeve in a penetrating manner. According to the sample collector for soil testing, a novel structural design is adopted, so that in the using process of the sample collector, the sampling barrel rotates and drills into soil to achieve sampling operation, after sampling is completed, an auxiliary pedal is operated to enable airflow to be discharged into the sampling barrel from an exhaust hole, soil left in the sampling barrel is cleaned, and the sampling efficiency is improved. And meanwhile, th
