Optionally, a sealing soft connecting belt is arranged between the output shaft of the hydraulic rod and the inner wall of the first collecting device.
Through adopting above-mentioned technical scheme, seal collection analysis case through sealed flexible connecting band, prevent that other granules from getting into.
Optionally, the bottom of the first collecting device is in threaded connection with a collecting and analyzing box.
Through adopting above-mentioned technical scheme, inside the granule entering collection analysis incasement after the collection, the granule that will collect the analysis incasement takes out and is used for each item analysis, will collect the granule of analysis incasement and pour out after the analysis finishes, is convenient for carry out unified processing to the granule.
Optionally, a limit groove is formed in the inner wall of the fixing block, a transmission gear is fixedly mounted inside the limit groove and driven by a motor, a tooth-shaped groove is formed in the outer wall of the hydraulic rod, and the tooth-shaped groove is meshed with the transmission gear.
Through adopting above-mentioned technical scheme, through inside the hydraulic stem will gather the filter membrane and regain collection device, it is rotatory to drive the hydraulic stem through drive gear, gathers the granule on the filter membrane when the hydraulic stem is rotatory and receives the influence of gravity to get into inside the collection analysis case.
In summary, the present application includes at least one of the following beneficial effects:
1. inside the air passes through the air inlet entering sample thief body, filter large granule impurity through the primary filter screen, when the air gets into sample thief body inside, it gets into inside the sample thief body to drive the collection filter membrane through the hydraulic stem, the air loops through two collection filter membranes, because the aperture of two collection filter membranes is different, so the particulate matter of different particle diameters stops respectively in the collection filter membrane of difference, through the hydraulic stem with gather inside the filter membrane income collection system again, it is rotatory to drive the hydraulic stem through drive gear, gather when the hydraulic stem is rotatory that the granule on the filter membrane receives gravity to influence to get into and collects inside the analysis case, the granule after gathering gets into and collects inside the analysis case, take out the granule in the collection analysis case and be used for each item analysis, can gather multiple particulate matter and improve the collection scope.
2. Before gathering, seal collection system through the second closing plate when gathering, can improve the accuracy of the granule of gathering.
