Description

Technical Field

[0001] The utility model relates to the technical field of air filtration, in particular to a cleaning device, an air filter and agricultural machinery equipment. Background Art

[0002] During the operation of the harvester, dust and debris in the air are filtered through the air pre-filter at the engine inlet to ensure that clean air is inhaled into the engine.

[0003] In the prior art, an air filter is usually provided with an air intake screen with a mesh structure, which can block large particles of debris such as crop straw and dust.

[0004] However, after working for a period of time, the surface of the air intake mesh will absorb a large amount of crop straw and dust, causing the mesh to be blocked. During the wheat harvest in some areas, a large amount of poplar and willow catkins exacerbated this situation, resulting in insufficient engine air intake, incomplete diesel combustion, increased fuel consumption, and engine weakness. In severe cases, the pre-filter mesh will be completely blocked and unable to take in air. To ensure the normal operation of the harvester, the operator needs to manually clean the surface of the air intake mesh of the pre-filter at regular intervals, which not only increases the operator's labor intensity, but also affects the harvesting efficiency.
