Abstract
The utility model discloses a pre -flock device that admits air for excavator, including the air intake hood and the connecting pipe that admits air, air intake hood is cylindric, is provided with a plurality of air vents on air intake hood's the lateral wall, and air intake hood's one end is provided with the otter board, and the other end is the open end. On the mounting panel in the excavator aircraft bonnet was fixed to the connecting pipe that admits air, its one end air inlet hose horizontal and excavator air cleaner cup jointed, and the other end slopes down, and just the open end with air intake hood cup joints. Should admit air the pre -flock unit bit in the aircraft bonnet, narrow meshed air intake hood can shift the low -frequency noise, prevents moreover that weeds from getting into air cleaner, and small, low in manufacturing cost has obviously reduced the noise in complete machine outside and the driver's cabin. The lower extreme of connecting pipe of admitting air adopts slope overall arrangement down, prevents the carwash, water gets into the engine when raining.
Description
Technical field
The utility model relates to excavator technical field, is specifically related to a kind of air inlet pre-flock device for excavator.
Background technique
At present, the mini-excavator that using and market is sold, its air-strainer and prefilter are all positioned at the outside of Engine Casing, air-strainer and prefilter are in operator cabin side, the noise of blasting of engine combustion sends from prefilter through gas handling system, cause the noise that operator cabin is interior and complete machine is outside large, the hearing health for driver is one to be threatened greatly.Meanwhile, air-strainer and prefilter are exposed to the outside of hood completely, stand the test of operating environment, and long-time exposure in the sun, and stands wind and weather, very easily aged deterioration.
The volume of air-strainer and prefilter is comparatively large, the limited space of Engine Casing, if air-strainer is arranged on hood inside, is difficult to existing prefilter to be placed in the lump in hood.If prefilter is arranged in hood, need to make improvements, in fact can adapt to the small space of engine hood, possess good pre-flock function, can noise be reduced.
Model utility content
The purpose of this utility model is to provide a kind of air inlet pre-flock device for excavator, and gas handling system is placed in hood, and isolation gas handling system noise, solution operator cabin is interior and complete machine noise is large.
To achieve these goals, the technical solution of employing is the utility model:
For an air inlet pre-flock device for excavator, comprise airscoop shroud and inlet pipe connection, described airscoop shroud is cylindric, and the sidewall of airscoop shroud is provided with multiple vent, and one end of airscoop shroud is provided with web plate, and the other end is opening end.Described inlet pipe connection is fixed on the mounting plate in digger hood bob, and its one end is laterally socketed with the air induction hose of excavator air-strainer, and the other end tilts down, and is socketed with the opening end of airscoop shroud.
Preferably, near one end of web plate, the sidewall of the opening end of airscoop shroud is evenly distributed with the breach of multiple strip in the middle part of the sidewall that described vent is evenly distributed on airscoop shroud.
Preferably, described vent is circular port, the web plate of airscoop shroud is also evenly distributed with multiple circular mesh identical with vent size and shape.
Preferably, described inlet pipe connection is bent into by metal pipe element, and its port tilted down is fixedly sleeved by the opening end of adjustable pipe clamp and airscoop shroud.
By adopting technique scheme, Advantageous Effects of the present utility model is: this air inlet pre-flock device is positioned at hood, narrow meshed airscoop shroud can shift low-frequency noise, and prevent weeds from entering air-strainer, volume is little, low cost of manufacture, significantly reduces the noise in complete machine outside and operator cabin.The lower end of inlet pipe connection adopts layout down, prevents carwash, water enters motor when raining.
Accompanying drawing explanation
Fig. 1 is the structural principle schematic diagram of a kind of air inlet pre-flock device for excavator of the utility model.
Fig. 2 is the structural principle schematic diagram of the utility model part, and what illustrate is pre-filter bowl.
Fig. 3 is the using state figure of a kind of air inlet pre-flock device for excavator of the utility model.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in detail:
Composition graphs 1 and Fig. 3, a kind of air inlet pre-flock device for excavator, comprises airscoop shroud 1 and inlet pipe connection 2, described airscoop shroud is cylindric, the sidewall of airscoop shroud 1 is evenly provided with multiple vent, and one end of described airscoop shroud 1 is provided with web plate 3, and the other end is opening end.In the middle part of the sidewall that described vent is evenly distributed on airscoop shroud 1 and near one end of web plate 3, described vent is circular port, the web plate 3 of airscoop shroud 1 is also evenly distributed with multiple circular mesh identical with vent size and shape.The sidewall of airscoop shroud 1 opening end is evenly distributed with the breach 4 of multiple strip.Described inlet pipe connection 2 is bent into by metal pipe element, inlet pipe connection 2 is arranged on the mounting plate 5 in the hood of excavator, the air induction hose 7 of inlet pipe connection 2 one end and excavator air-strainer is socketed, the other end tilts down, and the inclination port down of inlet pipe connection 2 is fixedly sleeved with the opening end of airscoop shroud by adjustable pipe clamp 6.
A kind of air inlet pre-flock device for excavator of the utility model, is specially adapted to 8 tons of excavators, for the feature that the hood inner space of 8 tons of excavators is narrow and small.This pre-flock device is positioned at hood, and the airscoop shroud 1 with vent can shift low-frequency noise, and prevents weeds from entering air-strainer, and volume is little, low cost of manufacture, significantly reduces the noise in complete machine outside and operator cabin.The part that the lower end of described inlet pipe connection 2 is connected with airscoop shroud 1 adopts layout down, can prevent carwash, water enters motor when raining.
Certainly; above-mentioned explanation is not to restriction of the present utility model; the utility model is also not limited in above-mentioned citing, the change that those skilled in the art make in essential scope of the present utility model, remodeling, interpolation or replacement, also should belong to protection domain of the present utility model.
