Conveying equipment and method for treatment of heavy metal lead and zinc in soil by using block chain technology

The invention discloses conveying equipment and a method for treatment of heavy metal lead and zinc in soil by using a block chain technology. A telescopic bin comprises an upper bin chamber, a contraction limiter, a lower bin chamber, lower bin sliders and upper bin slideways; the upper bin chamber located at the upper part is in an L-shaped design with two ends opened; the lower end of the upperbin chamber is sleeved with the lower bin chamber with the two ends opened; the upper bin slideways are fixed to the left side surface and the right side surface of the upper bin chamber correspondingly; the lower bin sliders are fixed to the left side surface and the right side surface of the lower bin chamber correspondingly; the upper bin slideways limit the lower bin sliders to slide on the surfaces of the upper bin slideways; and the contraction limiter is arranged at the top of one side of the upper bin chamber. The block chain technology is used for the conveying equipment for treatment of the heavy metal lead
