Description
Technical field
The utility model relates to the instrument and equipment field that wind erosion is measured, and particularly a kind ofly can collect and measure windy portable full blast to wind erosion quantity to sand-taped instrument.
Background technology
Sand-taped instrument is an important instrument of measuring soil drifting amount and research wind erosion desertification, and it is used to collect the sand dust of being carried by the unit width section with the acoustic wind sand drift in the unit interval.The design and the making of sand-taped instrument there is no unified standard, have the multiple sand-taped instrument of not isostructure and different trap efficiencies at present, mainly are classified as follows: the orientation according to air inlet is divided into horizontal sand-taped instrument and vertical sand-taped instrument; Be divided into passive type sand-taped instrument and active sand-taped instrument according to exhaust mode; Be divided into fixed sand-taped instrument and rotary sand-taped instrument according to fixed form; Also have single-point type sand-taped instrument and wire sand-taped instrument in addition.
The wedge shape sand-taped instrument is a passive type sand-taped instrument the most commonly used both at home and abroad at present, and this sand-taped instrument is the earliest by Greeley (1982) design, after Fryrear (1986), Rasmussen (1998) and Goossens people such as (2000) improve.The wedge shape sand-taped instrument has higher trap efficiency usually, add its making simple, cheap, carry advantages such as easy for installation and time saving and energy saving, therefore compare and have clear superiority with other sand-taped instrument.
Yet the wedge shape sand-taped instrument is fixed sand-taped instrument, can only observe a kind of soil drifting amount of wind direction.But under field conditions (factors), owing to be subjected to the influence of weather and topography and geomorphology, wind direction is changeable usually, and this has limited the use of wedge shape sand-taped instrument to a certain extent.The researcher usually uses following two kinds of methods to address this problem: 1. the wedge shape sand-taped instrument is installed collecting the wind erosion quantity of different wind directions on different wind directions, but this can make and installs and the surveying work complexity that becomes; 2. the wedge shape sand-taped instrument is improved to rotary sand-taped instrument, thereby make the sand inlet box haul rotate the wind erosion quantity of collecting different wind directions, but the manufacture craft of swivel bearing is had relatively high expectations, and owing to work under bad environment (strong wind, sand and dust, low temperature etc.), the rotating shaft of rotary sand-taped instrument is very easily broken down simultaneously.
