Description

Technical Field

[0001] The utility model relates to the technical field of sand collection, in particular to a rotary soil wind erosion gradient sand collection device. Background Art

[0002] Desertification is one of the most serious ecological and environmental problems facing the world. About one-fifth of the world's population and nearly one-third of the land are affected by desertification. The area of ​​deserts and desertified land in China is about 1.7 million km2, and the area affected is even larger. As one of the primary physical processes of desertification, the erosion, transportation and accumulation of surface materials under the action of wind, commonly known as wind-sand flow movement, has important theoretical and practical significance for understanding the laws of wind-sand movement and preventing and controlling desertification. Since the material transport of wind-sand movement mainly occurs near the surface and is mainly saltation movement, in order to understand the laws of wind-sand saltation movement, researchers have successively developed various types of sand collection devices, trying to reveal the changes of wind-sand movement in different directions and vertical directions through observation and experiments. At present, these sand collecting devices can be classified into two categories: one is a single-direction multi-path gradient sand collecting device, which is used to observe the vertical change law of the wind and sand flow, but cannot reflect the direction change synchronously; the other mainly includes various rotary sand collecting devices and omnidirectional sand collecting devices, which are used to collect moving sand in 8 or 16 directions, but generally can only collect sand within one or two fixed heights above the surface. In order to more comprehensively understand the changes and differences of wind and sand flow movement in different directions and at different heights, it is necessary to further improve the existing sand collecting devices.

[0003] After searching, it was found that the prior art publication number is CN204373879U, which discloses an eight-direction four-layer gradient sand collector for field use, characterized in that the sand collector includes an eight-direction four-layer gradient sand collection port, which is connected to the sand channel inside the sand collector, and an exhaust hole is provided on the outside, and the exhaust hole opening is covered with a 200-mesh stainless steel net. The sand collector is fixed on a circular fixed base, and a gradient sand collection nozzle is installed at the bottom, and each gradient sand collection nozzle is connected to the corresponding sand channel; below the circular fixed base is a barrel-shaped sand collector fixture, and the barrel-shaped sand collector fixture has 32 trapezoidal sand collectors arranged in concentric circles, and the gradient sand collection nozzle corresponds to the 32 trapezoidal sand collectors. The utility model can be used for field monitoring for a long time, which helps to reveal the differences in sand transport intensity and vertical structure of wind and sand flow in different directions, and is an indispensable field observation equipment for the study of wind and sand physics, wind and sand landforms and soil wind erosion.

[0004] Therefore, based on the above retrieval and combined with the existing ones, sand can be collected in eight directions, but it is impossible to collect wind and sand at different heights, which has limitations, and it is also impossible to increase the number of containers for collecting sand. In order to solve the problem that it is impossible to collect wind and sand at different heights and it is impossible to increase the number of containers for collecting sand, we propose a rotary soil wind erosion gradient sand collection equipment.
