The collection mechanism 201 includes a support frame 14 fixedly installed inside the machine frame 2 and a channel 5 fixedly installed on the upper surface of the support frame 14. One end of the channel 5 is fixedly connected to a collection hood 4. One end of the channel 5 passes through the analysis box 3 and extends to the inside. A blower pump 20 is provided at one end of the analysis box 3. The channel 5 passes through the analysis box 3 and is fixedly connected to the blower pump 20. A conversion elbow 6 is provided at one end of the analysis box 3. One end of the conversion elbow 6 is communicated with the blower pump 20. The conversion elbow 6 passes through the top arm of the analysis box 3 and enters the inside. A pushing mechanism 202 is fixedly installed at one end of the support frame 14. The pushing mechanism 202 includes a hydraulic push rod 13 fixedly installed at one end of the support frame 14 and a bidirectional rack plate 9 fixedly connected to the extending end of the hydraulic push rod 13. The upper surface of the machine base 1 is fixedly connected to the analysis box 3. Move the device to a predetermined analysis location, and then operate the external controller to turn on the switch of the blower pump 20. After the blower pump 20 is turned on, the polluted organic matter in the atmosphere is inhaled from the collection hood 4, partially filtered and then exported through the channel 5, and partially blown into the conversion elbow 6 and flows into the analysis box 3, reducing the wind speed of the polluted organic matter entering the conversion elbow 6, which is convenient for analysis. Under the partition of the capture plate 32, the upper part of the air in the analysis box 3 is relatively calm. After entering, the polluted organic matter freely settles with the change of gravity and naturally falls onto the capture plate 32. The displacement sensor 22 analyzes the speed of the settled polluted organic matter, and transmits the analyzed speed signal to the data analyzer 19 for display, so as to conduct the first analysis, which is convenient for comparing with the subsequent analysis data and providing more sufficient data for the analysis.
[0028] Specifically, a sedimentation analysis mechanism 204 is arranged inside the analysis box 3. The sedimentation analysis mechanism 204 includes two rotating rods 15 symmetrically and rotatably arranged inside the analysis box 3, and a capture plate 32 inserted through the rotating rods 15. Both rotating rods 15 pass through the analysis box 3 and extend to the outside, where a transmission gear 10 is fixedly sleeved. The bidirectional rack plate 9 is meshed and matched with the transmission gear 10. A stabilizing mechanism 205 is arranged on the upper surface of the machine base 1. The stabilizing mechanism 205 includes a limiting rod 12 arranged on the upper surface of the machine base 1 and a limiting collar 11 slidably sleeved on the outer surface of the limiting rod 12.

A pressure plate 29 is welded to the inner end of the ejector rod 39 located inside the triangular sleeve 21. A spring 33 is sleeved on the outer side of the ejector rod 39 at one end of the pressure plate 29. Then, the switch of the hydraulic push rod 13 is turned on from the external controller. After the hydraulic push rod 13 is turned on, the extending end is pushed out, driving the bidirectional rack plate 9 to move downward. Then, the two transmission gears 10 rotate in the same direction. After the transmission gears 10 rotate, they drive the rotating rods 15 to rotate. After the rotating rods 15 rotate, they drive the capture plate 32 to flip in the same direction, so as to pour the polluted organic matter settled on the capture plate 32 to the lower part of the analysis box 3. After the capture plate 32 is flipped to a certain angle, there is still residual polluted organic matter on the capture plate 32 that cannot slide down normally. After flipping, the bottom surface of the capture plate 32 abuts against the ejector rod 39, and then the push rod 40 compresses the spring 41. Then, the hydraulic push rod 13 is controlled to be reciprocally pushed up and down, so as to shake the capture plate 32 to shake off the residual polluted organic matter. The residual polluted organic matter falls into the second standard sieve 26.
[0029] Specifically, a driving mechanism 203 is fixedly installed at one end of the machine base 1. The driving mechanism 203 includes a driving motor 17 fixedly installed on the outer surface of the machine base 1 and a turntable 18 fixedly sleeved on the output end of the driving motor 17. An opening 16 is formed at one end of the analysis box 3. A swinging mechanism 206 is arranged inside the analysis box 3. The swinging mechanism 206 includes a connecting rod 38 rotatably connected to one end of the second standard sieve 26 and a mounting frame 36 fixedly arranged inside the analysis box 3. A limiting sliding rail 37 inserted through the opening 16 is fixedly installed at the upper end of the mounting frame 36. A U-shaped strip 34 is slidably arranged at the upper end of the limiting sliding rail 37. One end of the U-shaped strip 34 is rotatably connected to the connecting rod 38, and the other end of the U-shaped strip 34 is rotatably connected to a traction rod 35. The traction rod 35 is rotatably connected to the turntable 18. The switch of the driving motor 17 is turned on from the external controller. After the driving motor 17 operates, it drives the turntable 18 to rotate, thereby driving the traction rod 35 to rotate around the turntable 18, so as to pull the U-shaped strip 34 to slide reciprocally on the limiting sliding rail 37. When the U-shaped strip 34 slides, it pulls the connecting rod 38 to move, which is beneficial to providing a swinging force for the screening mechanism 207.
[0030] Specifically, a screening mechanism 207 is arranged inside the analysis box 3. The screening mechanism 207 includes a first standard sieve 25 and a second standard sieve 26 which are arranged up and down and movably arranged inside the analysis box 3, and a plurality of sliding grooves 23 respectively opened on the inner wall of the analysis box 3 and corresponding to both ends of the first standard sieve 25 and the second standard sieve 26. Sliders 24 are symmetrically arranged at both ends of the first standard sieve 25 and the second standard sieve 26. The sliding grooves 23 are slidably matched with the sliders 24. A gear transmission mechanism 208 is rotatably installed inside the analysis box 3. The gear transmission mechanism 208 includes a guiding gear 30 rotatably arranged inside the analysis box 3, and a lower rack plate 28 and an upper rack plate 31 respectively fixedly connected to one end of the first standard sieve 25 or the second standard sieve 26. Both the lower rack plate 28 and the upper rack plate 31 are meshed with the guiding gear 30. A first through port 7 corresponding to the lower rack plate 28 is opened at one end of the analysis box 3. When the U-shaped strip 34 slides, it pulls the connecting rod 38 to move, so as to drive the second standard sieve 26 to swing reciprocally. When the second standard sieve 26 swings, it drives the slider 24 to slide in the sliding groove 23, so as to shake the fallen contaminated organic matter and disperse it evenly, and screen it according to the different particle sizes of the contaminated organic matter. Then, the contaminated organic matter with smaller particle size falls into the first standard sieve 25. Under the swing of the second standard sieve 26, the upper rack plate 31 is driven to move. After the upper rack plate 31 moves, it drives the 30 to rotate. After the 30 rotates, it drives the lower rack plate 28 to move parallelly, so as to drive the first standard sieve 25 to move. After the first standard sieve 25 moves, the slider 24 continuously slides in the sliding groove 23, so as to further screen and detect.
[0031] Specifically, a data analyzer 19 is fixedly installed at one end of the analysis box 3. Seals 27 are arranged on the first standard sieve 25 and the second standard sieve 26. Displacement sensors 22 are symmetrically arranged on the inner top arm of the analysis box 3. A quartz membrane plate 8 is arranged inside the analysis box 3. A limiting rail matching the quartz membrane plate 8 is arranged inside the analysis box 3. The quartz membrane plate 8 is arranged in an interpenetrating manner with the analysis box 3. Then, the contaminated organic matter with smaller particle size falls onto the quartz membrane plate 8, and is taken out, rinsed and analyzed after the work is completed. The contaminated organic matter in the first standard sieve 25 and the second standard sieve 26 is also taken out, weighed and then analyzed, so as to improve the diversity of analysis and the accuracy of comprehensive analysis of particle size analysis.
[0032] When the utility model is in use, the user first moves the device to a predetermined analysis location, and then operates the external controller to turn on the switch of the blower pump 20. After the blower pump 20 is turned on, the polluted organic matter in the atmosphere is inhaled from the collection hood 4, and after being partially filtered through the channel 5, it is exported, and part of it is blown into the conversion elbow 6 and flows into the analysis box 3, reducing the wind speed of the polluted organic matter entering the conversion elbow 6, which is convenient for analysis. Under the partition of the capture plate 32, the upper part of the air in the analysis box 3 is relatively calm. After entering, the polluted organic matter freely settles with the change of gravity and naturally falls onto the capture plate 32. The displacement sensor 22 analyzes the speed of the settled polluted organic matter, and transmits the analyzed speed signal to the data analyzer 19 for display, so as to conduct the first analysis. After that, the switch of the hydraulic push rod 13 is turned on from the external controller. After the hydraulic push rod 13 is turned on, the extending end is pushed out, driving the bidirectional rack plate 9 to move downward. Then, the two transmission gears 10 rotate in the same direction. After the transmission gears 10 rotate, they drive the rotating rod 15 to rotate. After the rotating rod 15 rotates, it drives the capture plate 32 to flip in the same direction, so as to pour the polluted organic matter settled on the capture plate 32 to the lower part of the analysis box 3. After the capture plate 32 is flipped to a certain angle, there is still residual polluted organic matter on the capture plate 32 that cannot slide down normally. After flipping, the bottom surface of the capture plate 32 abuts against the ejector rod 39, and then the push rod 40 compresses the spring 41. Then, the hydraulic push rod 13 is controlled to push up and down reciprocally, so as to shake the capture plate 32 to shake off the residual polluted organic matter. The residual polluted organic matter falls into the second standard sieve 26. After that, the switch of the drive motor 17 is turned on from the external controller. After the drive motor 17 operates, it drives the turntable 18 to rotate, thus driving the traction rod 35 to rotate around the turntable 18, so as to pull the U-shaped strip 34 to slide reciprocally on the limit slide rail 37. When the U-shaped strip 34 slides, it pulls the connecting rod 38 to move, so as to drive the second standard sieve 26 to swing reciprocally. When the second standard sieve 26 swings, it drives the slider 24 to slide in the chute 23, so as to shake and evenly disperse the fallen polluted organic matter, and screen it according to the different particle sizes of the polluted organic matter. After that, the smaller particles fall into the first standard sieve 25. Under the swing of the second standard sieve 26, the upper rack plate 31 is driven to move. After the upper rack plate 31 moves, it drives the gear 30 to rotate. After the gear 30 rotates, it drives the lower rack plate 28 to move parallelly, so as to drive the first standard sieve 25 to move. After the first standard sieve 25 moves, the slider 24 continuously slides in the chute 23, so as to further screen. After that, the smaller polluted organic matter particles fall onto the quartz membrane plate 8, and are taken out, rinsed and analyzed after the work is completed. And the polluted organic matter in the first standard sieve 25 and the second standard sieve 26 is also taken out, weighed and then analyzed, which improves the diversity of analysis and the accuracy of particle size analysis is high through comprehensive analysis.
