Abstract

The invention discloses a sampling device for soft soil area reconnaissance and detection, related to the field of environment detection devices. The sampling device comprises a support base and standbars, a sampling head is arranged under the support base, and an upper end face is provided with an air cylinder for driving the sampling head to move; a side wall of the sampling head is verticallyprovided with a groove, and a switch board is vertically connected in the groove in a sliding manner; the inside of the sampling head is provided with a cavity, a bottom wall of the groove is providedwith a plurality of sliding holes communicated with the cavity at intervals, and the inside of each sliding hole is horizontally connected with a sampling tube in a sliding manner; one end, facing towards the groove, of the sampling tube is opening; and a driving mechanism for driving the sampling tube to slide horizontally is arranged in the cavity. The sampling device provided by the inventionhas the following advantages and effects: a plurality of sampling tubes at different altitudes are arranged, thus, synchronous sampling of soil layers of different depth is realized, sampling times isreduced, meanwhile, labor intensity of workers is reduced greatly, and the effect of conveniently acquiring soil layer samples of different depth is realized.

Description

technical field [0001] The invention relates to the field of environmental detection equipment, in particular to a sampling device for soft soil area survey and detection.
