Engine hood of construction machinery

Abstract

The invention provides an engine hood of an engineering machine, which includes a housing, power chambers, cooling plates and sliding doors; an upper end of that house is a power chamer, lower end iscooling plate, motor in power room, an upper end of that motor is provide with a rotary table, a turntable connecting block is arranged on the turntable, a link block of that rotary table is rotatablyconnected with the connecting column through the connecting column, a left side of that connecting post is rotatably connected with the locking block through a first limiting groove, a locking blockis rotatably connected with each other through a locking ring, a low end of that lock block is rotatably connected with the pull door lock, the sliding door lock is fixedly connected with the slidingdoor, an upper end of that sliding door is rotatably connected with the housing through a sliding door shaft, a low end of that sliding door is provide with a sliding door base, A liquid inlet is arranged in that lower left corner of the cooling plate, an infusion pipe is arranged in the liquid inlet, the other end of the infusion pipe is connected with the liquid outlet, a ventilation device is arrange in the middle of the cooling plate, a controller is arranged on the left side of the ventilation device, and a ventilation fan blade is arranged on the right side of the ventilation device. Thedevice is simple in use, effectively dissipates heat and lowers temperature to the engine, and is safe in operation.

Description

technical field [0001] The invention relates to the technical field of engineering machinery, in particular to an engine cover of an engineering machinery. Background technique [0002] Generally, the engine tends to generate heat and heat after a long time of operation. When the engine is idle, it is easy to get dust. When it is used again, the efficiency of the engine is not as good as before. Many existing hoods wrap the engine and set ventilation on the side. Although the effect of heat dissipation can be achieved in this way, the cooling effect is not good. At the same time, the temperature of the engine hood increases due to the engine's long-term operation, which often causes burns. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide an engine cover of construction machinery to solve the problems raised in the above-mentioned background technology. [0004] The technical problem solved by the present inventio...

Problems solved by technology

[0002] Generally, the engine tends to generate heat and heat after a long time of operation. When the engine is idle, it is easy to get dust. When it is used again, the efficiency of the engine is not as good as before. Many existing hoods wrap the engine and set ventilation on the side. Although the heat dissipation effect can be achieved in this way, the cooling effect is not good. At the same time, because the engine is hot after long-term operation, the temperature of the engine cover rises, and people are often burned.
