Description

Technical Field

[0001] The utility model relates to the technical field of agricultural equipment, in particular to a heat dissipation structure of a silage harvester. Background Art

[0002] The silage harvester is mainly used to harvest and chop grass, legume and other plants during the growing season, and process the chopped materials into silage.

[0003] The engine of the silage harvester needs to dissipate heat during operation, so a large amount of coolant is required. If the coolant temperature is too high, a heat dissipation device is required to cool it down. Existing silage harvesters often use industrial heat exchangers to dissipate the coolant, but the existing industrial heat exchangers require a large amount of airflow during operation to increase their heat dissipation efficiency. However, when the silage harvester is working in the field to cut and crush the grass, there will not only be a large number of insects, but also a large amount of dust. These insects and dust will be sucked into the panel of the heat exchanger, affecting the use effect of the heat exchanger.

[0004] For this reason, both sides of the heat exchanger of the existing forage harvester are usually covered with dust nets to prevent dust and insects from adhering to the heat exchanger. However, dust and insects will still adhere to the dust net, which will cause the airflow effect of the heat exchanger to deteriorate. For this reason, we propose a new heat dissipation structure for the forage harvester. Utility Model Content
