[0028] Furthermore, the guide assembly 21 includes a fixed frame 211, which is fixedly installed inside the smoke exhaust pipe 4. A rotating rod 212 is rotatably installed inside the fixed frame 211, an impeller 213 is fixedly installed at the bottom of the rotating rod 212, a feeding screw 214 is fixedly installed on the top of the rotating rod 212, and a cross rod 215 is fixedly installed on the top of the feeding screw 214, so that the exhaust gas moves up along the feeding screw 214.

[0029] Furthermore, through holes are opened at corresponding positions of the fixing frame 211 and the rotating rod 212, and the rotating rod 212 passes through the through holes and is fixedly installed with the impeller 213, so that when the smoke is discharged, the feeding screw 214 is automatically rotated to guide the smoke.

[0030] Furthermore, the absorption component 22 includes a filter plate 221, which is arranged inside the collection box 31. A connecting rod 222 is fixedly installed on the top of the filter plate 221, and an activated carbon filter 223 is fixedly installed on the end of the connecting rod 222 away from the filter plate 221. A scraper 224 is rotatably installed on the bottom of the filter plate 221, and a plug-in rod 225 is fixedly installed on the bottom of the filter plate 221. A pre-filtration operation is performed through the filter plate 221 to filter solid impurities in the flue gas, and then the activated carbon filter 223 is used to absorb harmful substances in the flue gas to prevent harmful substances in the flue gas from being directly discharged into the air.

[0031] Furthermore, a cross slot is opened at the corresponding position of the scraper 224 and the cross rod 215, and the cross rod 215 is inserted into the cross slot. A socket is opened at the corresponding position of the fixed block 33 and the plug-in rod 225, and the plug-in rod 225 is inserted into the fixed block 33. The rotation of the cross rod 215 drives the scraper 224 to rotate, and the scraper 224 rotates to scrape off the solid impurities attached to the bottom of the filter plate 221 and scrape them into the inside of the collection tank 32.

[0032] Embodiment 2:

[0033] See also Figure 5 , and combined with Example 1, it is further obtained that the installation mechanism 3 includes a collection box 31, the collection box 31 is arranged inside the smoke exhaust pipe 4, a collection groove 32 is opened inside the collection box 31, a fixing block 33 is fixedly installed inside the collection box 31, a smoke exhaust pipe 34 is provided on the top of the collection box 31, a threaded groove 36 is provided inside the smoke exhaust pipe 4, and a bolt 35 is threadedly installed inside the threaded groove 36. During installation, insert the connecting rod 225 into the socket of the fixing block 33, align the cross slot of the scraper 224 with the cross connecting rod 215, and screw on the bolt 35.

[0034] Furthermore, through holes are opened at positions corresponding to the exhaust pipe 34 and the collecting box 31 and the threaded groove 36, and the bolts 35 pass through the exhaust pipe 34 and the collecting box 31 from top to bottom in sequence, and are threadedly installed inside the threaded groove 36. By turning the bolts 35, the collecting box 31 can be removed, and the activated carbon filter 223 and the filter plate 221 can be removed.

[0035] In actual operation, when this device is used, the bottom of the plant protection machine connecting pipe 1 is fixed to the plant protection machine to discharge the smoke exhausted by the plant protection machine. After the smoke enters the exhaust pipe 4 through the plant protection machine connecting pipe 1, it first drives the impeller 213 to rotate, and the rotation of the impeller 213 drives the rotating rod 212 to rotate, and the rotation of the rotating rod 212 drives the feeding screw 214 to rotate, thereby causing the exhaust gas to move up along the feeding screw 214 without causing the solid impurities contained in the exhaust gas to fall back. The smoke moves up through the feeding screw 214 and passes through the filter plate 221 for pre-filtration operation to filter the solid impurities in the smoke. The filtered solid impurities fall into the collection tank 32, and the rotation of the feeding screw 214 drives the cross rod 215 to rotate, and the rotation of the cross rod 215 drives the scraper 224 to rotate. The scraper 224 rotates to scrape off the solid impurities attached to the bottom of the filter plate 221 and scrape them into the collection tank 32. It cooperates with the feeding screw 214 to prevent the solid impurities from falling back into the smoke exhaust pipe 4. The activated carbon filter 223 then absorbs the harmful substances in the smoke to prevent the harmful substances in the smoke from being directly discharged into the air. The filtered smoke is discharged through the smoke exhaust pipe 34. If it needs to be cleaned, turn the bolt 35, remove the collection box 31, remove the activated carbon filter 223 and the filter plate 221, clean them, and process the solid impurities inside the collection tank 32, which saves time and effort. During installation, insert the connecting rod 225 into the socket of the fixing block 33, align the cross slot of the scraper 224 with the cross connecting rod 215, and tighten the bolt 35.
