Combined hood for engineering machinery

Abstract

The invention discloses a combined hood for engineering machinery, which comprises an engine hood and a heat dissipation hood, and the heat dissipation hood is provided with an air intake grid and an exhaust grid; the heat dissipation hood is connected to the tail of the engine hood , the radiating cabin cover and the engine compartment cover are isolated by the tail end plate of the engine compartment cover; The outer cover is fixedly connected, and a first airtight cavity is formed between the engine compartment inner cover and the engine compartment outer cover; the heat dissipation compartment cover includes a heat dissipation compartment inner cover and a heat dissipation compartment outer cover positioned outside the heat dissipation compartment inner cover, and the heat dissipation compartment inner cover and The outer cover of the heat dissipation cabin is fixedly connected, and a second airtight cavity is formed between the inner cover of the heat dissipation cabin and the outer cover of the heat dissipation cabin. The combined hood has good sound insulation performance and anti-vibration performance.

Description

technical field [0001] The invention relates to a combined machine cover, in particular to a combined machine cover for engineering machinery. Background technique [0002] In the prior art, the hood of construction machinery is a one-piece structure, and a power system and a heat dissipation system exist simultaneously in the hood. The structure inside the power cabin is complex, and the air duct is extremely irregular. The heat of the power system preheats the cooling air, which seriously affects the heat dissipation performance of the construction machinery. At present, the hood of construction machinery is mostly made of square steel pipe or thick iron plate as the skeleton, covered with a layer of glass steel plate, and its anti-vibration performance and sound insulation performance are often not ideal. Contents of the invention [0003] Technical problem: The technical problem to be solved by the present invention is to provide a combined hood for engineering machin...
