Detailed Description
As shown in fig. 1-2, the dry air filter for the tractor comprises an outer shell 1, wherein an air outlet 2 is arranged at one end of the outer shell 1, and an air supply pipe 3 for communicating with an engine of the tractor is arranged on the air outlet 2.
The other end of the outer shell 1 is of an opening structure and is provided with an end cover 4 matched with the outline of the outer shell, and the end cover is specifically: the outer peripheral wall of the opening end of the outer shell 1 is provided with a first connecting flange 5, the outer peripheral wall of the end cover 4 is provided with a second connecting flange 6, and the first connecting flange 5 and the second connecting flange 6 are respectively provided with a plurality of identical threaded holes along the circumferential direction and are fixedly connected through screws 7 matched with the threaded holes. Further, a first seal groove 8 and a second seal groove 9 are respectively provided on the opposite sides of the first connection flange 5 and the second connection flange 6, and a seal ring 10 is provided in common inside the first seal groove 8 and the second seal groove 9.
The end cover 4 is close to one side of the outer shell 1 and is fixedly provided with a main filter cartridge 11 matched with the axis of the main filter cartridge, the main filter cartridge comprises a main filter cartridge and a safety filter cartridge arranged in the main filter cartridge, and one end of the main filter cartridge 11 close to the air outlet 2 is provided with a connecting port 12 matched with the air outlet 2.
The upper part of the outer shell 1 is provided with an air inlet 13, and the air inlet 13 is communicated with the lower end of a vertical connecting cylinder 14. The inside of the connecting cylinder 14 is fixedly provided with a spiral filter disc 15, and the upper end of the connecting cylinder 14 is fixedly provided with a support bracket 16 communicated with the connecting cylinder.
