Abstract
The invention relates to a rotary 8-direction sand sampler for measuring soil wind erosion in the wild. When wind-sand flow comes, a wind indicator as a rotary power drives a rectangular sand sampling probe to collect wind-drift sand of the vertical section against the wind. The inside of the sand sampling probe is an up-down integrated wind-sand flow channel. Two sides of the surface of a shell are provided with exhaust vents. A 200-mesh stainless steel mesh is welded above the exhaust vents. Most airflow outflows through the stainless steel mesh so as to reduce the speed of the sand flow inside the sand sampling probe. Then, flow direction of the wind-sand flow is changed, and grains of sand begin to fall. The grains of sand pass through a sand-guiding channel, flow into a sand discharge nozzle and finally are collected in fan-shaped sand-capture boxes in different directions. After the wind-sand flow passes by, sand samples are taken out from the fan-shaped sand-capture boxes according to directions and poured into bags to be weighed and metered, and soil wind erosion capacity of the wind-sand flow flowing into the fan-shaped sand-capture boxes in unit area and in unit time is calculated according to a computational formula. The rotary 8-direction sand sampler has a simple structure, is convenient to use, can widely be applied in researches in aspects of forest science, ecology, blown sand physics, sand prevention effectiveness observation in railway, highway, reservoir and industrial and mining engineering and the like, and is an essential instrument for observation of soil wind erosion.
Description
Technical field
The present invention relates to sand-taped instrument, relate in particular to a kind of for measuring the rotary 8 orientation sand-taped instruments of field soil wind erosion.
Background technology
Soil drifting is to affect one of serious problem of farmland, buildings, highway, railway, channel, water source and total environment.In China west droughty area, because wind speed is large, wind-sand activity is frequent, and this problem is more outstanding.A large amount of nutrients in strong wind soil in season lose because of wind erosion.Fine soil grain constantly blows mistake, has reduced Cultivated-land Fertility, loses yield-power, and it is the mobile phenomenon under wind-force effect.Wind carries various sand and dust grogs, makes it that displacement of different distance occur, and this phenomenon claims the transportation of wind.When subaerial wind speed is greater than 5m/s, the fine soil grain of 0.1～0.25mm particle diameter just can be handled upside down and form wind erosion.Grain size and the wind speed of the grogs of conventionally, being raised by wind are directly proportional.Concentration in the particle of soil drifting sand and dust grogs is with highly relevant.According to observations, the most grogs particles in stream all below near surface 500mm, and increase rising along with the increase of wind speed, and fine soil grain has 3 kinds with the mode of motion of wind-force: 1. the grains of sand of ﹤ 0.2mm are suspended state and move and claim to suspend when wind speed 5m/s; 2. the particle jumping in air-flow, collides ground during landing and the resilience that produces claims saltation; 3., after saltation particle impacts ground larger particles, slowly move forward that claiming wriggles moves.
China is one and is subject to the more serious country of soil drifting.The west area of China is main mainly with pastoral area, exactly because and soil drifting is fallen trees on a large scale and unrestrictedly herd the serious consequence causing in fragile ecologic environment.Soil drifting causes desertification, salinization of soil, formation Gobi desert.And China's desertification land has reached 3,580,000 k ㎡, account for 37% of national land area, and desertification land is still with the speed increment of 2100k ㎡/y.In order to effect a radical cure the consequence that soil drifting causes, must take suitable technical measures to prevent the structure of soil drifting.In scientific experiment activity, the mensuration of husky flux needs the multi-faceted collection observation data of long-term fixed point, and requires the observed result of husky flux to set up mutual relationship with wind speed, wind direction, to carry out research and the engineering calculation of soil drifting.So just need to develop a kind of instrument that can collect field soil wind erosion gradient Acquisition Instrument.
