DETAILED DESCRIPTION

[0018] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0019] Example 1

[0020] Reference Figure 1-3, an excavator exhaust treatment device, including a first connecting shell 1, a second connecting shell 2, a discharge pipe 4 is connected to the second connecting shell 2, the discharge pipe 4 is connected to the exhaust pipe, the discharge pipe 4 is an arc-shaped structure, the lower end of the first connecting shell 1 is connected to an inlet pipe 5, a gap is provided between the second connecting shell 2 and the first connecting shell 1, a connecting ring 14 is connected to the connecting column 6 through a connecting mechanism, a filter screen 13 is fixedly connected to the connecting ring 14, and the filter screen 13 is an activated carbon filter screen. The filter screen 13 is used as a filtering mechanism to intercept particulate matter in the exhaust gas. When the filter screen 13 is blocked and needs to be disassembled, the distance between the two connecting sleeves 3 is adjusted by using an adjusting mechanism to expose the connecting ring 14 and clean the filter screen 13.

[0021] Both ends of the connecting ring 14 are sleeved with connecting sleeves 3, and the two connecting sleeves 3 are adjusted by an adjusting mechanism. Sealing rings are arranged on the inner walls of the two connecting sleeves 3, and the sealing rings are abutted against the first connecting shell 1, the second connecting shell 2, and the connecting ring 14. Since the processing device is installed at the end position of the exhaust pipe, the temperature is relatively low. It is made of silicone rubber material, which can withstand the temperature and ensure the sealing effect.

[0022] The adjustment mechanism includes a bidirectional threaded rod 15, which is connected to the second connecting shell 2 through a bearing. Both ends of the bidirectional threaded rod 15 are threaded through the two connecting sleeves 3 respectively. By rotating the bidirectional threaded rod 15, the positions of the two connecting sleeves 3 are adjusted, thereby adjusting.

[0023] The connecting mechanism includes a support bearing 12, the inner axial surface of the support bearing 12 is fixedly connected to the connecting column 6, the outer bearing surface of the connecting column 6 is fixedly connected with a fixing ear 9, and the fixing ear 9 is fixedly connected to a connecting ring 14. When the connecting sleeve 3 is detached from the connecting ring 14, the filter screen 13 is cleaned by rotating the connecting ring 14 so as to deviate from the bottom of the connecting sleeve 3.

[0024] When in use, the positions of the two connecting sleeves 3 are adjusted by rotating the bidirectional threaded rod 15 to fully expose the connecting ring 14, and then the connecting ring 14 is rotated so that the connecting ring 14 deviates from the bottom of the first connecting shell 1 and the second connecting shell 2, so as to clean the filter screen 13.
