Referring to fig. 1 to 5, the tractor exhaust pipe protection structure of the invention comprises an exhaust pipe metal hard bag 1, an exhaust pipe cover 2 and a soft bag independent heat insulation belt 3. According to the invention, the exhaust pipe of the tractor is protected by triple combination of the metal hard bag 1 of the exhaust pipe, the exhaust pipe cover 2 and the independent heat insulation belt 3 of the soft bag, so that the heat insulation performance of the exhaust pipe can be greatly improved, the problem that inflammable sundries are easy to contact with the exhaust pipe and easy to burn is effectively prevented, and the effective protection of the exhaust pipe of the tractor is ensured, thereby improving the reliability of an engine of the tractor and further improving the reliability of the whole tractor.
The exhaust pipe metal hard bag 1 is sleeved on the exhaust pipe, and the exhaust pipe metal hard bag 1 is fixedly connected with the exhaust pipe. Specifically, the exhaust pipe metal hard bag 1 comprises a hard bag attaching layer 11, a hard bag filling layer 12, a hard bag reflecting layer 13 and a fixing layer 14 which are sequentially attached and arranged. The hard-pack adhesive layer 11 is attached to the outer wall of the exhaust pipe, and the fixing layer 14 is spot-welded on the exhaust pipe.
Wherein, the hard wrapping adhesive layer 11 is high silica cloth. The high silica cloth is directly attached to the surface of the high-temperature part, so that the reliability and stability of metal wrapping can be improved. The hard-pack filling layer 12 is made of glass fiber cloth, and aims to increase the heat insulation thickness and improve the heat insulation effect and the heat insulation quality. The hard-covered reflecting layer 13 is an aluminum-plated fiber cloth. The aluminum-plated fiber cloth is a material compounded by aluminum foil and glass fiber, wherein the aluminum foil can realize high-temperature reflection, the glass fiber has high-temperature resistance, and the compounded aluminum-plated fiber cloth has good high-temperature-resistant reflection performance. The fixed layer 14 is a stainless steel embossed plate. The thickness of the fixed layer 14 is 0.3mm to 0.6 mm. More specifically, the fixing layer 14 is made of a 0.5mm stainless steel embossing plate. Namely, the stainless steel plate is formed by adopting a pattern rolling and forming process, and the embossed patterns can play a role of reinforcing ribs and increase the strength of the plate. The stainless steel embossed plate can be designed into one or more blocks according to the shape of the exhaust pipe, and if the embossed plate is designed into a plurality of blocks, the blocks are connected by adopting a welding process. Through the multilayer composite heat insulation wrapping technology of the metal hard bag 1 of the exhaust pipe, the wrapping coverage of the exhaust pipe can be effectively improved, the wrapping quality of the exhaust pipe is improved, and therefore the heat insulation performance of the exhaust pipe is improved.
In addition, the exhaust pipe metal hard bag 1 is sleeved with an exhaust pipe cover 2, and the exhaust pipe cover 2 is detachably mounted on a lug 4 of the exhaust pipe.

Wherein, the soft bonding layer is bonded on the exhaust pipe cover 2. In addition, the soft package adhesive layer, the soft package filling layer and the soft package reflecting layer are respectively high silica cloth, glass fiber cloth and aluminum-plated fiber cloth. That is, the soft bag independent heat insulating tape 3 of the present embodiment is different from the exhaust pipe metal hard pack 1 in that the soft bag independent heat insulating tape 3 does not have the fixed layer 14. The thicknesses of the adhesive layer, the filling layer and the reflecting layer of the independent heat insulation belt 3 for the soft bag and the metal hard bag 1 for the exhaust pipe can be adjusted more.
The independent heat insulation belt 3 of soft package of this embodiment is designed according to the cladding condition of blast pipe metal hard package 1 and the cladding condition of blast pipe cover 2, and the principle is that cover the giving way position of blast pipe flange and blast pipe cover 2 that blast pipe metal hard package 1 can not wrap up completely. Specifically, be equipped with a plurality of holes of stepping down 31 on the independent heat insulating belt 3 of soft package, one side of the independent heat insulating belt 3 of soft package is equipped with the grooving 32 that extends to the hole of stepping down 31, and the branch pipe interlude of blast pipe is in the hole of stepping down 31. When installing soft packet of independent heat insulating tape 3, with the 3 upsets of the soft packet of independent heat insulating tape of grooving 32 both sides, make grooving 32 grow to make smooth grafting of branch pipe in the hole 31 of stepping down, guaranteed the smooth installation of soft packet of independent heat insulating tape 3, can also promote protective structure's parcel quality simultaneously.
The both ends of the independent thermal-insulated area of soft package 3 all are equipped with the silicone tube 33 that is used for the fixed independent thermal-insulated area of soft package 3 of ligature. Wherein, 3 every ends in soft packet of independent thermal-insulated area all are equipped with two high temperature resistant silicone tubes 33. When the soft package independent heat insulation area 3 is fixed in the installation, the silicone tube 33 is directly bound and fastened in a proper position, so that the installation of the soft package independent heat insulation area 3 is stable, simple and convenient.
Preferably, the other side of the soft-bag independent heat insulation belt 3 is provided with an isolation bending belt 34, and the isolation bending belt 34 is lapped on the joint of the engine body 5 and the exhaust pipe cover 2. Further wrapping of the exhaust pipe is achieved through the isolation bending belt 34, and sundries are effectively prevented from entering the exhaust pipe cover 2 from the connection position of the engine body 5 and the exhaust pipe cover 2.
The foregoing is only a preferred embodiment of the present invention, and it should be noted that those skilled in the art can make various changes and modifications without departing from the structure of the invention, which will not affect the effect of the invention and the practicability of the patent.
