Embodiment Construction
[0018] The technical solution of the present invention will be further described below in conjunction with the accompanying drawings.
[0019] like Figure 1 to Figure 3 As shown, a combined hood for construction machinery of the present invention includes an engine compartment cover 1 and a heat dissipation compartment cover 2 . An air intake grid 3 and an exhaust grid 4 are arranged on the heat dissipation cabin cover 2 . The heat dissipation cabin cover 2 is fixedly connected to the afterbody of the engine compartment cover 1 . The heat dissipation compartment cover 2 and the engine compartment cover 1 are separated by the tail end plate 5 of the engine compartment cover 1 . The engine compartment cover 1 includes an engine compartment inner cover 6 and an engine compartment outer cover 7 located outside the engine compartment inner cover 6 . The engine compartment inner cover 6 and the engine compartment outer cover 7 are fixedly connected, and a first airtight cavity 8...

The invention discloses a combined machine cover for an engineering machine. The combined machine cover comprises an engine compartment cover body and a heat dissipation compartment cover body, and the heat dissipation compartment cover body is provided with an air inlet grid and an air exhaust grid; the heat dissipation compartment cover body is connected to the tail portion of the engine compartment cover body, and the heat dissipation compartment cover body and the engine compartment cover body are isolated through a tail end plate of the engine compartment cover body; the engine compartment cover body comprises an engine compartment inner cover unit and an engine compartment outer cover unit located on the outer side of the engine compartment inner cover unit, the engine compartment inner cover unit is fixedly connected with the engine compartment outer cover unit, and a first closed cavity is formed between the engine compartment inner cover unit and the engine compartment outer cover unit; the heat dissipation compartment cover body comprises a heat dissipation compartment inner cover unit and a heat dissipation compartment outer cover unit located on the outer side of the heat dissipation compartment inner cover unit, the heat dissipation compartment inner cover unit is fixedly connected with the heat dissipation compartment outer cover unit, and a second closed cavity is formed between the heat dissipation compartment inner cover unit and the heat dissipation compartment outer cover unit. The combined machine cover has good sound insulation performance and shock resistance.
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...
