Embodiment 1

[0027] Example one, as figure 1 , Figure 5 The road dust sampler includes a dust collecting hood 1, the top of the dust collecting hood 1 is connected with a suction pipe 2, the suction pipe 2 can be connected with the sampler, the bottom is provided with a dust collecting port 3, and the upper wall of the dust collecting hood 1 is provided with a suction pipe 2. The dust disturbance device 8 includes a micro-fan 81 and a micro-motor 82. The micro-fan 81 is fixed on the inner wall of the top of the dust-collecting hood 1, and a micro-motor 82 and a micro-fan 81 are fixed on the corresponding position of the outer wall of the dust-collecting hood 1. The rotating shaft of the micro-motor 82 is connected to the output shaft of the micro-motor 82. The micro-motor 82 is provided with a switch 83. The switch 83 can start the micro-motor 82 to work, and the micro-motor 82 drives the micro-fan 81 to rotate; An annular groove, a dust blocking structure 4 is clamped in the groove,...

Embodiment 2

[0030] Example two, as figure 2 , Figure 8 As shown, the road dust sampler includes a dust collecting hood 1, the top of the dust collecting hood 1 is connected with a suction pipe 2, the bottom is provided with a dust collecting port 3, the upper wall of the dust collecting hood 1 is provided with a dust disturbance device 8, and the dust disturbance device 8 includes an air pump 84, the top of the dust collecting hood 1 is provided with a through hole 11, the through hole 11 is provided with a filter plate 85, the filter plate 85 can filter the dust in the outside air, and prevent excess dust from entering the dust collecting hood 1, The side wall of the filter plate 85 is provided with a circle of grooves 851, and an O-ring 852 is arranged in the groove 851. On the one hand, the ring 852 enhances the sealing performance, and on the other hand, the filter plate 85 can be stuck in the through hole 11 of the dust cover 1 by means of the friction force between the O-ring ...

Embodiment 3

[0032] Embodiment 3, in Embodiment 2, since the air pump 84 is located at the top of the dust collecting hood 1, it blows down from the top when blowing air, and the dust at the bottom of the dust collecting hood 1, especially the dust at the corners, is not very disturbing. large and not very comprehensive. In order to improve this aspect, further, such as image 3 As shown, the road dust sampler includes a dust collecting hood 1, the top of the dust collecting hood 1 is connected with a suction pipe 2, the bottom is provided with a dust collecting port 3, the upper wall of the dust collecting hood 1 is provided with a dust disturbance device 8, and the dust disturbance device 8 includes an air pump 84, a through hole 11 is arranged at the top of the dust collecting cover 1, a filter plate 85 is arranged in the through hole 11, a groove 851 is arranged on the side wall of the filter plate 85, and an O-shaped groove is arranged in the groove 851. The other side wall of the O...

Abstract

A road dust sampler relates to a sampling device which solves the problem of inconvenient collection of road dust per unit area. Including the dust collection cover, the top of the dust collection cover is connected with a suction pipe, and the bottom is provided with a dust collection port. There is a dust blocking structure, the dust collecting port is also provided with a dustproof cover, and the end of the suction pipe is also provided with an end cover. The present invention can solve the problem of collecting dust on the road, and can prevent the intrusion of the surrounding dust outside the unit area, so that the data collected this time is more accurate, and it is beneficial to accurately analyze the source of dust on the unit area, from point to surface Determine the amount and source of various types of dust on the road near the road.

Description

technical field [0001] The invention relates to a device capable of collecting dust in a unit area for detection of dust source and particle size, in particular to a road dust sampler. Background technique [0002] Under the action of certain dynamic conditions, the dust on the street is raised and mixed one or more times, and enters the ambient air to form particles with a certain particle size distribution, which has an increasingly serious impact on ambient air quality and human health. Dust has become the primary pollutant in urban air, and the control of open sources such as road dust will become one of the focuses of urban air particle pollution control. Instruments such as dust detectors are only used to detect particles in the air, and cannot be used to collect dust in a closed area on the road. SUMMARY OF THE INVENTION [0003] The purpose of the present invention is to provide a road dust sampler to solve the problem of inconvenient collection of road dust ...
