Embodiment 1

[0032] Such as figure 1 and figure 2 As shown, this embodiment provides a dust collection device, which includes a box body 1 and a sliding plate 2 .

[0033] Specifically, the box body 1, which is hollow inside, is surrounded by a front side panel 11, a rear side panel 12, a left side panel 13, and a right side panel 14, that is, the front side panel 11, the rear side panel 12 , the left side plate 13, the right side plate 14 end-to-end and enclose a rectangular cylinder structure; the bottoms of the front side plate 11, the rear side plate 12, the left side plate 13, and the right side plate 14 are Blade structure3. It should be noted that the blade structure 3 has a sharp point, which is convenient for inserting the front side board 11 , the rear side board 12 , the left side board 13 and the right side board 14 into the snow accumulation.

[0034] Further specifically, the lower part of the front side panel 11 and the rear side panel 12 is provided with a slot 4, and o...

Embodiment 2

[0044] refer to figure 1 and figure 2 , the present embodiment provides a kind of dust collection method, and it comprises the steps:

[0045] Step S1, insert the bottom of the box body 1 into the snow on the ground surface, insert the end of the sliding plate 2 with the blade structure 3 into the slot 4 of the rear side panel 12 and slide to the slot 4 of the front side panel 11, the box The interior of the main body 1 is filled with snow samples, and the snow samples are transferred to the sample box.

[0046] In this embodiment, when collecting dust falling on the surface of the snow, first slide out the sliding plate 2, so that the bottom is the front side plate 11, the rear side plate 12, the left side plate 13, and the right side of the knife-edge structure. The plate 14 enters the snow accumulation by 2-3 cm; secondly, by sliding the sliding plate 2 and making the sliding plate 2 seal the bottom of the box body 1, the snow accumulation sample is prevented from mixing...

Abstract

Embodiments of the present invention disclose a dustfall collection device and method. The dustfall collection device comprises a box body and a sliding plate; the box body with a hollow interior is formed by enclosing a front side plate, a rear side plate, a left side plate, and a right side plate; the lower portions of the front side plate and the rear side plate are both provided with a clamping slot separately; and one end of the sliding plate with a blade structure is movably inserted into the clamping slot of the front side plate, and the other end of the sliding plate is movably inserted into the clamping slot of the rear side plate. According to the dustfall collection device and method provided by the embodiments of the present invention, the design is reasonable; and natural space distributed dustfall can be accurately collected by using the snow blanket method, the characteristics of dustfall can be measured and analyzed, comparison analysis is performed on the dustfall andthe local soil to better analyze the spatial distribution characteristics, the sources, the transportation route, the settlement mechanism, the environmental effects, and the like of the dusttfall, the impact of dustfall on the formation process of the surface soil can be revealed, and the understanding of the formation and evolution of aeolian loess in East Asia is enhanced.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of sampling, and in particular to a dust collection device and method suitable for rainy and snowy weather in the north. Background technique [0002] Dustfall, also known as "falling dust", refers to the dust particles in the atmosphere that can naturally settle on the ground due to its own gravity. The particle size is usually greater than 10 microns. Measuring the amount of dust falling can know the degree of pollution and hazards of falling dust in the air. For the classification of dustfall, according to the weather visibility conditions when the dustfall is settling, the atmospheric dustfall can be divided into non-dusty weather dustfall and sandstorm weather dustfall, and dustfall in sandstorm weather can be divided into floating dust, blowing sand and sandstorm; According to the precipitation during the dust fall, the dust fall can be divided into wet dust fall and dry dust...
