It is the thin plate of trellis work on rear side of described hood.
The utility model, by testing the noise of whole motor, is found out noise source, is carried out structure optimization to hood, hood main body installs Sound-proof material and heat insulation foam respectively, while not affecting radiating effect, improve serviceability and Security; Seamless installation between acoustical cotton and hood main body, significantly reduces the noise outside hood.
Accompanying drawing explanation
Fig. 1 is hood main body apex structure schematic diagram of the present utility model.
Fig. 2 is the structural representation on the left of hood main body of the present utility model.
Embodiment
Illustrate below in conjunction with accompanying drawing and illustrate the utility model with embodiment.
Have a hood for sound insulation and decrease of noise functions, comprise hood main body, hood main body comprises on rear side of hood side panel, hood top and hood.Hood side panel comprises left sideboard and right sideboard.Hood main body is formed by square steel pipe welded, and its skeleton is firmly light.Hood side panel and hood top are equipped with Sound-proof material 6.Be the thin plate of trellis work on rear side of hood, enhance radiating effect.The bottom of hood main body and front side are empty, are conveniently loaded on the motor of loader.
Hood top is provided with top Heat sink 3, as shown in Figure 1.Top Heat sink 3 is punched-plates, which saves the weight of hood main body, improves the radiating efficiency of motor.Top Heat sink 3 is provided with oval radiation hole.The top of hood main body 1 is also provided with relief opening 4 and suction port 7.The left-right integrated shaping steel plate of 3mm is provided with around relief opening 4 and suction port 7.Be provided with Sound-proof material 6 on the right side of the Heat sink 3 of top, this Sound-proof material 6 is provided with a circular radiation hole I 5, and the oval radiation hole on the area ratio top Heat sink 3 of circular radiation hole I 5 is large, and this is because it is positioned at engine side, needs heat diffusion area larger.The left and right sides of relief opening 4 is all provided with Sound-proof material 6, and the left side of suction port is provided with Sound-proof material 6.Both sides, hood top are provided with hinge 8.
Hood side panel periphery is provided with Sound-proof material 6, in the middle of hood side panel, is provided with side door 1.Side door 1 is provided with side Heat sink 2, Sound-proof material 6 and heat insulation foam 11.As shown in Figure 2, structure and the right sideboard of left sideboard are symmetrical arranged right sideboard.Side Heat sink 2 is punched-plate, which is provided with the circular radiation hole II that area is less.Side door 1 both sides are provided with and are separately installed with air spring 9, and side door 1 can be connected with hood side panel by air spring 9.Open air spring 9, can conveniently side door 1 be taken off on the left of hood main body, convenient maintenance.The lower end of hood side panel is provided with stiffening rib 10, adds the rigidity of hood main body, decreases the noise of its vibration.The upper end of hood side panel is provided with hinge 8, and it matches with the hinge 8 on hood top.Hood side panel is connected with hood top by hinge 8.Hinge-opening 8, can unload corresponding hood side panel separately.
Sound-proof material 6 is fixed in hood main body by gluing or clasp nail, effectively prevents coming off of Sound-proof material 6, and conveniently changes Sound-proof material 6 as required.Between hood main body and Sound-proof material 6, seamless installation, effectively reduces noise, reaches top standard of the same trade.Sound-proof material 6 controls the propagation path of engine noise effectively, reduces the noise of loader.
The utility model detects according to the noise in whole loader operation process, and find noise source and its propagation path and the structure of hood main body that designs, compared with prior art, outside engine noise reduces 2-4dB to whole hood main body.
