The utility model discloses a soil collecting device for detecting semi-volatile organic pollutants, which comprises a main body, a feeding component is arranged in the main body, and a moving component is arranged on one side of the main body; the feeding
assembly comprises a moving plate, a
telescopic cylinder is mounted on the outer wall of the bottom of the moving plate through bolts, a push plate is mounted at the output end of the
telescopic cylinder through bolts, and a motor is mounted in the center of the outer wall of the bottom of the push plate through bolts. By means of the arranged feeding
assembly, after a motor is started, a feeding
auger can be driven by the motor to rotate, in the rotating process of the feeding
auger, soil can be effectively collected, meanwhile, by means of reasonable configuration of a
servo motor and a conveying
auger, the device can efficiently carry out conveying operation on the soil, in addition, through arrangement of a
telescopic cylinder, the conveying efficiency is improved, and the conveying efficiency is improved. The device can flexibly collect and process soil at different depths, and the design facilitates soil collection and subsequent detection work of a user, so that the practicability of the device is remarkably improved.
