Abstract
The utility model discloses a sand collection instrument, which relates to the field of the sand collection instrument meeting the sampling requirement of indoor and outdoor wind erosion research. The sand collection instrument comprises a sand inlet 1, a ventilation screen 2, a sand sampling box 3, a slot 4 and a sand collection box 5 and is characterized in that the front end of the sand sampling box 3 is provided with the sand inlet 1; the top part of the sand sampling box 3 is provided with the ventilation screen 2; and the slot 4 is arranged between the sand sampling box 3 and the sand collection box 5. The sand collection instrument has a simple structure, a small and exquisite appearance, lightness and convenience in carrying, low manufacturing cost, convenience in operation and good sampling performance, especially has higher collection efficiency on fine particles which are less than 100mum in particle size and has great influence to the ambient air, and meets the sampling requirement of the indoor and outdoor wind erosion research.
Description
Technical field
The utility model relates to the sand-taped instrument field of the sampling request of indoor and outdoor wind erosion research, influences the sand-taped instrument of bigger fine particle less than 100 μ m, to surrounding air especially for gathering particle diameter.
Background technology
Soil drifting can make upper soll layer alligatoring, thin material minimizing, soil layer attenuation, organic matter and nutrient loss on the one hand to a large amount of carryings and the sedimentation of surface soil, reduces the soil fertilizer moisture holding capacity, causes soil degradation, soil desertification; On the other hand, thin particulate matter can be transported to far place with the wind in the soil drifting process, produces a large amount of aerosol particles, and is suspended in the atmosphere, and air quality is descended, and pollutes location and surrounding enviroment, has a strong impact on human body health.Therefore, it is pressing for of control soil drifting desertification that the soil drifting problem is carried out comprehensive and systematic research, and uses sand-taped instrument accurately be familiar with in Soil Erosion Modelling Study and grasp the dust storm kinetic property, have important and practical meanings with measuring silt discharge, observe the Structure of wind-Sand Flow feature and study the dust storm characteristics of motion in the indoor wind-tunnel in the open air.
At present, used multiple sand-taped instrument in the wind erosion research at home and abroad, such as: tipping bucket type sand-taped instrument, flat sand-taped instrument, multichannel square opening sand-taped instrument, MWAC collector, BSNE collector or the like.And mainly there is following several deficiency in existing sand-taped instrument: 1) complex structure is difficult for making; 2) bulky, carry inconvenience; 3) the husky effect of collection is bad, for low to the capture rate of the bigger fine particle of air quality influence; 4) cost an arm and a leg.Therefore, at these deficiencies, a kind of sand-taped instrument of optimal design is the key of deeply eroding and studying.
The utility model content
The purpose of this utility model is the deficiency at existing sand-taped instrument, provide a kind of simple in structure, external form is small and exquisite, it is light to carry, low cost, easy to operate, the sampling performance is good, particularly for particle diameter less than 100 μ m, the fine particle acquisition rate higher sand-taped instrument bigger to surrounding air influence.
The technical solution of the utility model is:
A kind of sand-taped instrument, by sand inlet 1, the screen 2 that ventilates, adopt sandbox 3, slot 4 and sand collecting box 5 and forms, adopting sandbox 3 front ends is sand inlet 1, adopts sandbox 3 tops and shields 2 for ventilating, adopting between sandbox 3 and the sand collecting box 5 has slot 4.
The described sand-taped instrument left and right sides is 8-15 ° of outwards expansion, and integral body is wedge shape.
Described sand inlet is a rectangle, protrudes to adopt sandbox and be lower than to adopt the sandbox top.
Described ventilation screen is stainless steel filtering net.
Whirligig can be added in described sand-taped instrument bottom makes sand inlet over against wind direction.
The beneficial effects of the utility model are:
1) simple in structure, be easy to make affected convenience.The sand inlet of sand-taped instrument, ventilate screen with adopt sandbox and combine together, sand-taped instrument integral body is only removable for adopting sandbox and sand collecting box two parts, the two is continuous by slot.
2) external form is small and exquisite, carries lightly, is applicable to indoor and outdoor wind erosion monitoring needs.The not enough 1dm3 of sand-taped instrument external overall volume, general assembly (TW) is less than 100g.
3) collect husky better performances.By dynamic property experiment and trap efficiency experiment such as finishing, dynamic property such as this sand-taped instrument better and wind speed change to its etc. the dynamic property influence not quite; Acquisition rate is higher, average acquisition rate to 0.10mm-0.25mm particle size range soil sample is 83.58%, average acquisition rate to 0.075mm-0.10mm particle size range soil sample is 81.16%, the average acquisition rate of right＜0.075mm particle size range soil sample is 60.93%, and this sand-taped instrument is fit to gather saltation and the suspended moving particle of part.
4) low cost.
Description of drawings
Fig. 1 is the structural representation of the utility model sand-taped instrument.
Embodiment
Below in conjunction with accompanying drawing the utility model is done further detailed description:
As shown in Figure 1, the ventilation screen 2 that formed by wide rectangle sand inlet 1, the 120 order stainless steel filtering nets of 10mm height * 20mm of the utility model sand-taped instrument, the high sand collecting box 5 of sandbox 3, slot 4 and 25mm of adopting that 40mm is high are formed.Adopting the sandbox front end is sand inlet, and it protrudes to adopt sandbox 20mm and be lower than and adopts sandbox top 5mm.Adopt the sandbox top and be the screen that ventilates, each back gauge of screen of ventilating is adopted each limit 5mm of sandbox top.The sand-taped instrument left and right sides is outwards expanded gradually with 11 ° angle, and integral body is wedge shape.
In carrying out indoor and outdoor wind erosion observation, will adopt sandbox and sand collecting box when eroding sampling by intermediate seal preferably slot be integrated, and make the sand-taped instrument sand inlet over against wind direction.After adopting husky the end, adopt sandbox and can take down from sand collecting box along slot and take a sample.By collected sand and dust are weighed, can further calculate silt discharge.
