Closed organic contaminated soil feeding device

The utility model discloses a closed organic contaminated soil feeding device which comprises a conveying chamber, a feeding cavity is formed in the conveying chamber, a horizontally-arranged conveying channel is formed in the conveying chamber, a concentration opening is formed in the side wall of the conveying chamber and communicated with the conveying channel, and a vertical conveying opening penetrating into the conveying channel is formed in the bottom in the feeding cavity. The semi-gear is driven to rotate under the action of the motor, so that the linkage plate reciprocates, and when the linkage plate reciprocates, the pushing block moves back and forth under the action of the linkage rod and the pushing rod; according to the utility model, the pushing blocks in the two conveying channels move relatively to continuously convey soil into the concentration port through the conveying channels, and accumulated water in the soil cannot enter the machine by utilizing the sealing effect between the pushing
