Description

Technical Field

[0001] The utility model relates to the field of exhaust pipe heat insulation covers, in particular to a heat insulation cover for agricultural exhaust pipes. Background Art

[0002] Agricultural machinery often operates in high-temperature environments, generating hot gases from exhaust pipes, posing a risk of burns and fire. Improving the thermal insulation performance of exhaust pipe heat shields can effectively reduce the risk of injury to nearby personnel and crops, improving operational safety. High-temperature gases from agricultural machinery exhaust pipes generate significant amounts of heat radiation, which can cause thermal damage to surrounding crops and equipment. Optimizing the design and material selection of heat shields can reduce the spread of heat radiation, minimizing the thermal impact on the surrounding environment and protecting crops and equipment.

[0003] The existing exhaust pipe heat insulation cover has a general heat insulation effect, poor anti-vibration effect, and relatively general heat dissipation effect.
