In this application, when the filter unit inside the exhaust gas purifier 5 needs to be cleaned or maintained in the later stage, the flip cover body 31 is first opened, and then the pulley 4 is pulled out from the fixed cover body 3, and then the exhaust gas purifier 5 is removed from the pulley 4 for maintenance. When disassembling the exhaust gas purifier 5, the maintenance of the exhaust gas purifier 5 can be completed without repeatedly disassembling and installing the fixed engine cover, and it is convenient to detect and inspect the exhaust gas purifier 5 during use.

[0031] Specifically, in this embodiment, the hinge axis of the flip cover 31 on the fixed cover 3 is located at the top of the fixed cover 3 .

[0032] Specifically, in this embodiment, the method of fixing the flip cover body 31 on the fixed cover body 3 adopts the existing technology, which will not be elaborated here.

[0033] In some embodiments, the fixing assembly 6 may be configured as follows: Figure 2 , Figure 3 and Figure 4 See also Figure 2 , Figure 3 and Figure 4The fixing assembly 6 includes a pull rod 61, a stopper 62 and a fixing member 63. The pull rod 61 is fixedly mounted on the tailstock 2 and is located below the pulley 4. The length direction of the pull rod 61 is set along the sliding direction of the pulley 4; the stopper 62 is sleeved on the outside of the pull rod 61, and the stopper 62 is slidably set on the pull rod 61 along the length direction of the pull rod 61, and the stopper 62 can abut against the outer surface of the pulley 4; the fixing member 63 is threadedly connected with the pull rod 61, and is used to tighten the stopper 62 against the pulley 4. A fixing plate is fixedly mounted on the tailstock 2 inside the fixed cover 3, and the pulley 4 can abut against the fixing plate when moving into the fixed cover 3, so as to limit the position of the pulley 4.

The stopper 62 is slidably set on the pull rod 61, and the stopper 62 can abut against the side of the pulley 4 away from the fixing plate. Thereby, the pulley 4 is limited between the limiting member 62 and the fixing plate. The limiting member 62 can be pressed against the pulley 4 by the fixing member 63 to complete the fixing of the pulley 4, with a simple structure and convenient operation.

[0034] Preferably, in this embodiment, when the pulley 4 is fixed inside the fixed cover 3 , the limiting member 62 is located on a side of the pulley 4 close to the opening of the fixed cover 3 .
