Abstract

The invention relates to a land freeze-thaw wind erosion simulation measurement device, aiming at solving the problem that the existing land freeze-thaw wind erosion simulation measurement device cannot measure the influence of different gradients on a wind erosion experiment. A fan is rotationally connected to the box body wall of one end of a test box, a sliding way is fixedly connected to the bottom face in the test box, a control lead screw is rotationally connected into the sliding way, a positioning sliding block is in threaded connection with the control lead screw, an electric push rod is fixedly connected to the positioning sliding block, a supporting bottom plate is rotationally connected to the electric push rod, and a supporting top plate is rotationally connected to the supporting bottom plate. Positioning plates are arranged at the two ends of the supporting top plate respectively, positioning holes are formed in the positioning plates, connecting holes are formed in the two ends of the supporting bottom plate respectively, the connecting holes are connected with the corresponding positioning holes through bolts, and the rotating shaft connecting end of the supporting bottom plate and the supporting top plate is located on one side of the fan. And two ends of the first baffle plate and the second baffle plate are fixedly connected with the test box. The device can measure the influence of different gradients on the wind erosion experiment.

Description

technical field [0001] The invention relates to the field of soil testing, in particular to a land freeze-thaw wind erosion simulation measurement device. Background technique [0002] When measuring the degree of permafrost affected by wind erosion, it is necessary to use the land freeze-thaw wind erosion simulation measurement device to conduct simulation experiments. [0003] The existing land freeze-thaw wind erosion simulation measurement device can simulate the wind erosion effect of different wind forces on frozen soil at a specified temperature. The surface is parallel to the air flow, and the effect of different slopes on wind erosion experiments cannot be measured. Contents of the invention [0004] The invention provides a land freeze-thaw wind erosion simulation measurement device to solve the problem that the existing land freeze-thaw wind erosion simulation measurement device cannot measure the influence of different slopes on wind erosion experiments.
