Because the utility model discloses an increase rubber pipe sleeve and with the mode of larynx hoop with rubber bottom ring -opening connected in star, be fixed in the aircraft bonnet with rubber pipe sleeve and corrugated metal pipe box and lap adjustment rubber pipe sleeve and corrugated metal pipe that can be convenient to this purpose that reaches empty filter hole of hermetically sealed casing apron and silencer hole has that dustproof and waterproof is effectual, total noise of centrifuge hangs down, simple to operate's advantage.
Description
Technical field
The utility model relates to a kind of engineering machinery, particularly relates to a kind of air filter and silencing apparatus and is arranged on sealing configuration on hood.
Background technique
As shown in Figure 1, a kind of air filter commonly used and silencing apparatus are arranged on the sealing configuration on hood, comprise hood cover plate 1 ', air filter 2 ', silencing apparatus 3 ', connecting leg 4 '.Two mounting holes, 11 ', 12 ', mounting hole 11 ' is offered for installing air filter 2 ' in described hood cover plate 1 ' top, and another mounting hole 11 ' is for fixing a silencer 3 '.Described air filter 2 ' suction tude and silencing apparatus 3 ' tail pipe are located in two mounting holes 11 ', 12 ' at hood cover plate 1 top respectively.Be connected by connecting leg 4 ' between air filter 2 ' with silencing apparatus 3 '.This traditional hood cover plate 1 ' is due to component manufacture and assembly error, in final assembly process, air filter 2 ' is larger relative to the actual deviation of hood cover plate 1 ' with silencing apparatus 3 ' tail pipe, the mode that usual employing strengthens the perforate of hood cover plate 1 ' solves, and affects overall appearance quality and has a certain impact to total noise of centrifuge also tool.
Summary of the invention
The purpose of this utility model is to provide a kind of product appearance quality is good, dustproof and waterproof is effective, total noise of centrifuge is low, easy for installation air filter and silencing apparatus to be arranged on sealing configuration on hood.
For achieving the above object, technical solution of the present utility model is:
The utility model is the sealing configuration that a kind of air filter and silencing apparatus are arranged on hood, comprises hood cover plate, air filter, silencing apparatus, connecting leg; Two mounting holes are offered at described hood cover plate top, and air filter air inlet pipe and muffler tail pipe are located in two mounting holes at hood cover plate top respectively, are connected between air filter with silencing apparatus by connecting leg; Also comprise rubber sleeve and wavy metal pipe box; Described rubber sleeve upper socket is in air filter air inlet pipe and fixed by larynx hoop, and rubber sleeve bottom is socketed in the interior along upper of hood cover plate top mounting holes; Described metal bellows cover top to be socketed on muffler tail pipe and to be fixed by larynx hoop, and wavy metal pipe box bottom is connected to the mounting hole periphery of hood cover plate.
The outer, bottom of described rubber sleeve is provided with a ring annular groove, and this annular groove is socketed in the interior along upper of hood cover plate top mounting holes.
Described wavy metal pipe box lower weld is on connecting plate, and connecting plate is bolted on hood cover plate.
After adopting such scheme, because the utility model is by increasing rubber sleeve and by the mode of larynx hoop and rubber bottom open loop connected in star, rubber sleeve is fixed on hood cover plate, because rubber sleeve has certain stretchability and the feature of flexibility, according to practical set error, can easily adjust, reach the object in hermetically sealed casing cover plate air filter hole with this; When considering that complete machine works, muffler tail pipe temperature is higher, therefore by increasing wavy metal pipe box, with larynx hoop and bolt, wavy metal pipe box is fixed on hood cover plate, according to the assembly error of muffler tail pipe, the length of adjustment wavy metal pipe box and deflection direction, reach the object in hermetically sealed casing cover plate silencing apparatus hole, there is the advantage that product appearance quality is good, dustproof and waterproof is effective, total noise of centrifuge is low, easy for installation.
Adopt the sealing means shown in this patent, there is following several effect:
1, complete machine appearance quality is promoted
Adopt the mode of traditional increasing hood cover plate perforate, have a strong impact on the appearance quality of complete machine, use rubber sleeve
And the sealing of wavy metal pipe box, air filter and muffler tail pipe and the smooth transition of hood cover plate, play the effect of decoration to complete machine outward appearance, improve the appearance quality of complete machine.
2, there is certain dust-proof, waterproof action
Because the working condition of loader is comparatively severe, after adopting this kind of sealing means, can prevents the foreign material such as rainwater and flying dust from flying in a large number, good effect is played to the performance of motor, decrease the corrosion of rainwater simultaneously.
3, to reduction total noise of centrifuge, there is certain contribution
Hood air filter hole and sealing front and back, silencing apparatus hole, by complete machine noise reduction experimental test, shown by test data analyzer, can reduce total noise of centrifuge after sealing.
4, improve efficiency of assembling, avoid doing over again
Current final assembly process, due to assembly error, still there will be the problem that air filter, muffler tail pipe and hood aperture are interfered, assembly crewman needs to spend the more time to go to process interference problem, after adopting this kind of mode to seal, in sealing surface, can the size of suitable expanded hole, outward appearance is not had an impact, overcome the interference problem caused by foozle, be convenient to assembling, first time has just assembled, and is conducive to improving efficiency of assembling.
Below in conjunction with the drawings and specific embodiments, the utility model is further described.
Accompanying drawing explanation
Fig. 1 commonly uses air filter and silencing apparatus to be arranged on structural representation on hood;
Fig. 2 is schematic diagram of the present utility model.
Embodiment
As shown in Figure 2, the utility model is the sealing configuration that a kind of air filter and silencing apparatus are arranged on hood, comprises hood cover plate 1, air filter 2, silencing apparatus 3, connecting leg 4, rubber sleeve 5 and wavy metal pipe box 6.
Two mounting holes 11,12 are offered at described hood cover plate 1 top, and a mounting hole 11 is for installing air filter 2, and another mounting hole 11 is for fixing a silencer 3.Described air filter 2 is connected by connecting leg 4 with between silencing apparatus 3, and air filter 2 suction tude and silencing apparatus 3 tail pipe are located in two mounting holes 11,12 at hood cover plate 1 top respectively.
The outer, bottom of described rubber sleeve 5 is provided with a ring annular groove 51, this annular groove 51 is socketed in the interior along upper of hood cover plate 1 top mounting holes 11, gap plugging between air filter 2 suction tude and the mounting hole 11 of hood cover plate 1 is lived, play the effect of sealing air filter 2 hood aperture.Rubber sleeve 5 upper socket is in air filter 2 suction tude and fixed by larynx hoop 7.
