Embodiment
Below in conjunction with the accompanying drawings, specific embodiment of the present utility model is described in detail, it is to be understood that this practicality
New protection domain is not limited by embodiment.
Specific embodiment of the present utility model is such：
Embodiment one
As shown in figure 1, a kind of vertical silencer structure, including vertical body 1, the vertical bottom of body 1 is provided with can be with exhaust
The installation seat plate 2 that pipe is connected and is tightly connected, the top surface of vertical body 1 are upwardly extended provided with gradually narrowed transition conduit 3, transition
The top of pipe 3, which is provided with, to be upwardly extended and to the outlet bend pipe 4 of curving；The installation seat plate 2 of the vertical lower end of body 1 passes through bolt group
Part connects with the blast pipe of agricultural engine, and the contact area of installation seat plate 2 and blast pipe is big, is connected firmly, and prevents vertical tube
Body 1 occurs to loosen and tilted, and good airproof performance, effectively prevents gas leakage, helps to reduce noise；The top of vertical body 1 is
Gradually narrowed transition conduit 3, the pipe shaft of transition conduit 3 is smooth, is not easy to be stained with thing and hangs thing, in farmland cultivation, harvesting, corn stigma,
The debris such as leaf stalk are not easy to hang over the top of vertical body 1, and debris is not easy to overstock, and in the presence of mechanical shaking, debris can not
It is disconnected to slide, risk on fire can be effectively reduced, simple in construction, improvement is preferable, and height is hung over for a long time so as to avoid crops
Fire accident occurs on the muffler of temperature, protects the safety of personnel, avoids farm machinery from being burned out and cause economic loss；
Outlet bend pipe 4 on vertical body 1 is set to curving, its opening direction in vertical direction with certain angle, prevents rain
Water, debris enter in muffler, ensure that exhaust is unimpeded and the normal use of muffler, the environment that greatly strengthen muffler adapt to
Property.
In the present embodiment, the vertical bottom of body 1 is provided with caving inward and with being connected the adapter 5 of installation seat plate 2, can root
According to the height of the gas outlet of muffler, the adapter 5 of corresponding size is set, 5 is then will take over and connects with the vertical body 1 of full-length
Connect, increase the vertical scope of application of body 1, the vertical body 1 of same model is can be applied to different farm machineries, make vertical body
1 meets the design requirement of standardized structural, is adapted to produce in enormous quantities, reduces production cost and use cost；The plate of installation seat plate 2
Face and the outer surface of vertical body 1 are adapted, and the plate face of installation seat plate 2 is suitable with the diameter of vertical body 1, makes whole noise reduction
The space hold of device structure is small, installation seat plate 2 is firmly connected with blast pipe, the reasonable utilization space of and can, moreover, whole noise reduction
It is not easy to accumulate crops on the outer surface of device structure, the safe to use of agricultural machinery is effectively ensured.
Multiple risers 6 being connected with installation seat plate 2 are uniformly provided with the present embodiment 2, the surface of revolution of adapter 5, by vertical
Plate 6 can will take over 5 and is more firmly connected with installation seat plate 2, make whole muffler structure connection more firm, be suitable for disliking
Bad working environment.
In the present embodiment, transition conduit 3 is the tapered tubular construction gradually narrowed upwards, and the taper of tapered tubular construction is 1：2
To 1：0.25, be not easy on the circular conical surface of tapered tube configuration to accumulate crops must stalk, and conical surface design, handling ease, taper
The both ends of transition conduit 3 be connected easily with vertical body 1, outlet bend pipe 4, be easy to weld；The taper of tapered tube configuration is 1：2 to
1：When between 0.25, the fibrous root of crops is hardly deposited on the outer surface of transition conduit 3, moreover, the height of transition conduit 3
It can control in certain scope, save material, reduce weight, help to make whole muffler structure keep balance and stability, because
This, is 1 in certain taper：2 to 1：Performance in 0.25 for muffler structure has a positive facilitation, and using effect is good.
According to actual use and experiment, the taper of tapered tubular construction is 1：When 0.5, the using effect of muffler structure compared with
Good, the integrated data such as the manufacturing of muffler structure, transport, material cost is optimal.
Embodiment two
As shown in Fig. 2 muffler structure is substantially the same with the structure in embodiment one, difference is, transition conduit 3 is
The cambered surface tubular construction gradually narrowed upwards, the surface of cambered surface tubular construction are equally not easy to accumulate the debris such as the fibrous root of crops, stood
A diameter of D of formula body, when the curvature K of cambered surface tubular construction is 1/D to 1/2D, the height of whole muffler structure meets muffler
The stability of installation, and the hardly debris such as fibrous root of accumulation accumulation crops in the cambered surface of transition conduit 3, effectively prevent because
Muffler temperature is too high because fire accident occurs, and ensures the safety of personnel and property.
