At present, airborne dust is collected in the equipment of sampling detection, in order to collect airborne dust sample, the device of sampling in real time
It is exposed in atmosphere, sampling head generally only have one, the result data that the sample of collection is measured does not possess reliability, and sampling head
Upwards, rainwater can be caused to pour into, airborne dust is not collected.
Utility model content
The utility model is in view of the deficiency of the prior art, there is provided one kind sampling reliability is high, and can prevent
The dust from construction sites harvester that rainwater pours into.
The technical solution that the utility model solves above-mentioned technical problem is as follows：A kind of dust from construction sites harvester, including inspection
Device body and fixing device are surveyed, on the securing means, the detection device body includes vertical for the detection device body installation
Column, the upper end of the column are equipped with fixed disk, the circumferentially uniformly distributed multiple air inlet pipe of the fixed disk, and the fixed disk is equipped with mixed gas
Chamber, the air inlet pipe are connected by hose with mixed air cavity, and asepwirator pump is equipped with the mixed air cavity.
The beneficial effects of the utility model are：There are multiple air inlet pipe collection gases, into after mixed air cavity, the data ratio of collection
It is more accurate.
Further, the air inlet pipe tilts down.
It is using the above-mentioned further beneficial effect of technical solution：Prevent rainwater from entering air inlet pipe.
Further, blade is equipped with the mixed air cavity, the blade is published in instalments in the top and bottom of mixed air cavity by bearing
Between.
It is using the above-mentioned further beneficial effect of technical solution：Make gas mixing evenly, testing result reliability is more
It is high.
Further, sliding block is socketed with the column, the air inlet pipe is hinged by supporting rod and sliding block, on the column
The buckle that position-limiting action is played to sliding block is additionally provided with, the air inlet pipe can open and close.
It is using the above-mentioned further beneficial effect of technical solution：The air inlet pipe can open and close, preferably anti-
Only rainwater enters, and when not detect, adjusting slider, which closes air inlet pipe, can save space.
Further, the fixing device is base.
Further, the arrival end of the air inlet pipe is in horn-like.
It is using the above-mentioned further beneficial effect of technical solution：It can ensure that gas preferably enters air inlet pipe.
The utility model further relates to a kind of dust from construction sites detection device, described using above-mentioned dust from construction sites harvester
Mixed air cavity is connected with dust detector, sets the asepwirator pump built in the dust detector.
Brief description of the drawings
Fig. 1 is the structure diagram of dust from construction sites harvester in the utility model；
Fig. 2 is the structure diagram of dust from construction sites detection device in the utility model；
In the accompanying drawings, the list of designations represented by each label is as follows：1st, base, 2, column, 3, air inlet pipe, 4, sliding
Block, 5, mixed air cavity, 6, supporting rod, 7, fixed disk, 8, hose, 9, blade, 10, dust detector, 11, buckle.
Embodiment
The principle and feature of the utility model are described below in conjunction with attached drawing, example is served only for explaining this practicality
It is new, it is not intended to limit the scope of the utility model.
As shown in Figure 1, a kind of dust from construction sites harvester, including detection device body and fixing device, the detection dress

Connected with mixed air cavity 5, asepwirator pump is equipped with the mixed air cavity.
The air inlet pipe 3 tilts down, and prevents rainwater from entering air inlet pipe 3.
Be equipped with blade 9 in the mixed air cavity 5, the blade 9 by bearing publish in instalments mix air cavity 5 top and bottom it
Between.
Sliding block 4 is socketed with the column 2, the air inlet pipe 3 is hinged by supporting rod 6 and sliding block 4, on the column 2
Be additionally provided with the buckle 11 that position-limiting action is played to sliding block 4, the air inlet pipe 3 can open and close, preferably prevent rainwater into
Enter, when not detect, adjusting slider 4, which closes air inlet pipe 3, can save space.
The fixing device is base 1, and the lower end of the column 2 is installed on the base 1.
The arrival end of the air inlet pipe 3 is in horn-like.
The utility model further relates to a kind of dust from construction sites detection device, is filled as shown in Fig. 2, being gathered using above-mentioned dust from construction sites
Put, the mixed air cavity 5 is connected with dust detector 10, the asepwirator pump (being not drawn into figure) built in the dust detector 10
The above is only the preferred embodiment of the present invention, is not intended to limit the utility model, all in this practicality
Within new spirit and principle, any modification, equivalent replacement, improvement and so on, should be included in the guarantor of the utility model
Within the scope of shield.
