Abstract
The utility model relates to a rotary eight-direction sand collector used for field soil wind erosion measuring. When wind-drift sand flow comes, a wind indicator serves as a rotation power to drive a rectangular sand collection probe to collect wind-drift sand flow of a vertical section against the wind. The inside of the sand collection probe is provided with an up-and-down integrated wind-drift sand flow channel; air vents are distributed at both sides of the surface of a shell; a 200-mesh stainless steel net is welded on the air vents; and most of air flow goes out through the 200-mesh stainless steel net to force sand flow in the sand collection probe to slow down and change the direction of wind-drift sand flow, then sand grains begin to drop, and sand-dust grains pass through a sand guide channel and are gathered to fan-shaped sand receiving boxes in different directions through a sand discharge nozzle. After the wind-drift sand flow, sand samples are taken out from the sand receiving boxes in order of direction and are poured into a bag to be weighed and calculated, and the quantity of soil wind erosion flowing into the fan-shaped sand receiving boxes per unit area and per unit time is calculated according to a calculation formula. The rotary eight-direction sand collector used for field soil wind erosion measuring is simple in structure and easy to use, can be widely used in researches in respects of forestry, ecology, wind sand physics, sand prevention benefit observation of railway, highway, reservoir and mining projects, and the like, and is an instrument essential to soil erosion observation.
Description
Technical field
The utility model relates to sand-taped instrument, relates in particular to a kind of rotary 8 orientation sand-taped instruments for measuring the 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.At China's 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 the 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.During 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 when subaerial wind speed.Grain size and the wind speed of the grogs of usually, 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 that jumps in air-flow, collision ground during landing and the resilience that produces claims saltation; 3. after saltation particle impacts the ground larger particles, move forward slowly that claiming wriggles moves.
China is one and is subjected 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 that causes in the ecologic environment of fragility.Soil drifting causes desertification, salinization of soil, formation Gobi desert.And China's desertification land has reached 3,580,000 k ㎡, accounts for 37% of national land area, and desertification land is still with the speed increment of 2100k ㎡/y.Must take suitable technical measures to prevent the structure of soil drifting in order to effect a radical cure the consequence that soil drifting causes.In the 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, in order to carry out research and the engineering calculation of soil drifting.So just need a kind of instrument that can collect field soil wind erosion gradient Acquisition Instrument of development.
