The guide columns 201 are fixedly installed on the inner wall of the outer casing 5, and bushings are provided between the mounting seats 202 and the guide columns 201. This allows the mounting seats 202 to slide against the guide columns 201 using the bushings, protecting the inner walls of the holes in the mounting seats 202 and effectively extending their service life. The guide columns 201 also guide the mounting seats 202. Multiple connecting rods 204 are fixedly connected to the top of the mounting seats 202, and a top cover 203 is fixedly connected to the top of each connecting rod 204. Both sides of the bottom of the mounting base 202 are fixedly connected to driven racks 205. A connecting shaft 207 is provided on one side of each driven rack 205. The driven racks 205 mesh with driving gears 206. The connecting shaft 207 is rotatably connected to the inner wall of the outer casing 5, allowing the connecting shaft 207 to drive the driving gears 206 to rotate, thereby moving the driven racks 205 and enabling the mounting base 202 to be raised or lowered. Two driving gears 206 are fixedly connected to the connecting shaft 207. A worm gear 208 is fixedly connected to the end of the connecting shaft 207. A worm 209 is provided on one side of the worm gear 208. A drive motor 210 is fixedly connected to the end of the worm 209. 9 meshes with the worm gear 208. The output shaft end of the drive motor 210 is connected to the connecting shaft 207 via the worm 209 and the worm gear 208, enabling the drive motor 210 to drive the connecting shaft 207 to rotate. The self-locking function of the worm gear 208 and the worm 209 can also lock the mounting base 202. The mounting base 202 is equipped with a purifier 211, which is a particulate filter and an SCR catalytic converter, effectively purifying and treating diesel exhaust gas. Limiting plates and fixed seats 212 are respectively provided on both sides of the purifier 211. A movable arm 213 is slidably connected inside the fixed seat 212, and a fixed connection is made to the end of the movable arm 213. The pressure plate 214, the limiting plate, and the fixing seat 212 are all fixedly installed on the top surface of the mounting base 202. The pressure plate 214 and the limiting plate are respectively set on both sides of the purifier 211, so that the purifier 211 can be fixed by the pressure plate 214 and the limiting plate. A movable block 216 is slidably connected to one side surface of the movable arm 213. A handle 217 is fixedly connected to the end of the movable block 216. A limiting groove 215 is opened on one side surface of the fixing seat 212. The cross-sectional shape of the limiting groove 215 is set as an inverted U-shape, and the handle 217 is set inside the limiting groove 215, so that the movement of the handle 217 can be limited and guided by the limiting groove 215.

[0019] Please see Figure 1 and Figure 4The sound insulation and protection mechanism 4 includes a fixed sound insulation plate 401 and a movable sound insulation cover 402.

The two guide sliders 403 are threadedly connected to movable screws 404. The ends of the two movable screws 404 are connected to drive shafts 405 through gear pairs. Rotating heads 406 are fixedly connected to the ends of drive shafts 405. By rotating the rotating heads 406, the rotating heads 406 drive the drive shafts 405 to rotate. The rotation of the drive shafts 405 simultaneously drives the two movable screws 404 to rotate. The rotation of the movable screws 404 drives the guide sliders 403 to move. The movement of the guide sliders 403 drives the movable sound insulation cover 402 to move, so that the movable sound insulation cover 402 can be combined and separated from the fixed sound insulation plate 401. This can facilitate the sound insulation and protection of the unit body 3 and facilitate the maintenance of the unit body 3.

[0020] During operation, the drive motor 210 drives the worm gear 209 to rotate, which in turn drives the worm wheel 208 to rotate. The worm wheel 208 then drives the connecting shaft 207 to rotate, which in turn drives the drive gear 206 to rotate. The drive gear 206 then drives the driven rack 205 to move, which in turn moves the mounting base 202 along the guide post 201, lifting the purifier 211 out of the outer casing 5. Then, the handle 217 is pushed along the limit slide groove 215, which in turn moves the movable arm 213, which in turn moves the pressure plate 214, allowing for the disassembly and assembly of the purifier 211. This effectively improves the convenience of maintenance.
