Wetland soil sampling device

The invention discloses a wetland soil sampling device, which comprises a sampler, a slurry pump, hoses and a distributor. The distributor includes an inlet distributor and an outlet distributor. A drilling head is arranged at the lower end of the sampler; a sealing plate in vertical sliding connection with the sampler is arranged on the side wall of the sampler; and a plurality of through holes Iare formed in the sealing plate. The internal cavity of the sampler is divided into a plurality of sampling chambers by a plurality of partition boards; a through II is formed in the side wall of thesealing plate of each sampling chamber; and the through holes I and the through holes II are in a sliding staggered or aligned communication manner by the sliding plate. A plurality of hoses are arranged and are communicated with the sampling chambers and the inlet distributor as well as the outlet end of the outlet distributor. Therefore, a defect of the soil separation caused by the insufficient friction force between t
