Description
Technical field
The utility model relates to a kind of constituent elements of engine air filtering system, particularly relates to a kind of air-guide device of benzvalene form strainer.
Background technique
Engine air filtering system of the prior art is made up of benzvalene form strainer and fine cleaner mostly, as shown in Fig. 1,2, benzvalene form strainer (1) is communicated with by suction tude (2) with fine cleaner, and fine cleaner comprises (4) two kinds of dry-type air cleaner (3) and wet-type cleaners.Existing benzvalene form strainer mainly is made up of strainer lid, swirl vane ring and laying dust dish, during engine operation, begin to suck the air that dust granule is contained in the external world, inhaled air can produce high speed rotating behind the swirl vane ring, when being inhaled into strainer, air produces high speed rotating, dust granule can be under action of centrifugal force, be thrown toward the inwall of laying dust dish, stopped behind the top of dust granule arrival strainer, just move laterally and rely on own wt to drop in the laying dust dish of benzvalene form then; The air that contains small amount of dust after strainer filters carries out next step filtering from the filter core that suction tude flows into the fine cleaner.At present, the air filtration system of motor all is to be fixedly mounted on the car body of engineering machinery, farm machinery etc., the suction port height immobilizes, when reaper, tractor are under the high dust concentration environment operation, can't suck cleaned air from high position more, can amass full dust very soon in the laying dust dish of benzvalene form strainer, the filter core of fine cleaner can be stuck with paste full by dust, so need frequent cleaning laying dust dish, change the filter core of fine cleaner, in order to avoid dust stops up filter core, cause engine power to descend, influence motor working life.
Summary of the invention
For addressing the above problem, the purpose of this utility model provides a kind of air-guide device of simple in structure, easy for installation, benzvalene form strainer that using effect is good.
For achieving the above object, the utility model adopts following technological scheme:
A kind of air-guide device of benzvalene form strainer, it comprises an air scoop, air scoop is enclosed within the suction tude outside, and form cavity between the suction tude, the air scoop upper end is connected with the benzvalene form strainer, the lower end is connected on suction tude or the air-strainer, and the air scoop sidewall is provided with at least one suction port, and suction port is provided with connecting tube.
Further technological scheme, when described air scoop was connected with suction tude, the air scoop bottom surface can be from bottom to top raised shape in the shape of a spiral.
Further technological scheme can be provided with the ring-type guide plate that rises in the shape of a spiral from bottom to top in the cavity between described air scoop and the suction tude.
Further technological scheme can be provided with several guide vanes in the cavity between described air scoop and the suction tude, and guide vane one end is fixed on the air scoop madial wall, and the other end is fixed on the suction tude outer side wall.
Further technological scheme, described air scoop shape can be the uniform section cylindrical shape, or the variable cross section cylindrical shape.
Further technological scheme, the center line of described connecting tube and air scoop has certain angle.
Further technological scheme, described connecting tube is straight tube or bend pipe.
Owing to adopt aforesaid technological scheme, the utlity model has following superiority:
The air-guide device of this benzvalene form strainer, when reaper, tractor operation, connecting tube on its air scoop can connect long air pipe or the flexible air pipe that stretches into the high-altitude, so that suck cleaner air from the higher position, delay the obstruction of benzvalene form strainer, prolong the working life of air filtration system, can reduce the maintenance downtime maintenance times; And in the vehicle driving, because of rocking of producing of car body high position more violent, the dust that causes having collected in the benzvalene form strainer is kicked up once more, increase the weight of the obstruction of air-strainer, therefore intake manifold length can be shortened, reduce the height of benzvalene form strainer, make whole air filtration system structure compact more, can rearrange the mounting point that air filtration system is installed, make things convenient for personnel's maintaining.The utility model is reasonable in design, simple in structure, with low cost, practical, using effect is good, has great promotional value.
