Description

Technical Field

[0001] The invention relates to an engine protection device, and more particularly to a tractor exhaust pipe protection structure. Background Art

[0002] With the development of science and technology, the degree of mechanization of modern agriculture has been improved, and more and more agricultural machinery has been applied to on-site agricultural production. By 2020, the comprehensive mechanization level of agricultural machinery in my country's crop cultivation and harvesting has reached about 60%. As the power source of agricultural machinery products and the main force of agricultural machinery mechanization, tractors have a huge market demand space.

[0003] Although tractors are relatively complex machines with different types and sizes, they are all composed of three major parts: engine, chassis and electrical equipment, and each of them is indispensable. Among them, the engine is the device that generates power for the tractor and is the heart of the entire tractor. Its function is to convert the thermal energy of the fuel (usually diesel) into mechanical energy to output power to the outside. Because continuous combustion is required to provide output power, the temperature of the high-temperature components of the engine, especially the temperature of the exhaust pipe, is very high. Although the operating environment of tractors is much better than that of corn harvesters, rice harvesters, etc., the market occasionally receives feedback on tractors catching fire due to exposed high-temperature components. Therefore, how to improve the protection capabilities of tractors and reduce the risk of tractor fires has always plagued the development of the tractor industry.

[0004] At present, the protection of tractor engine exhaust pipes generally uses metal hard wrapping, that is, adding a layer of heat insulation cotton on the surface of the exhaust pipe, and then wrapping it with a formed metal sheet and welding it to the exhaust pipe. Because the insulation structure is simple and it is a single-layer insulation cotton structure, the insulation effect is difficult to guarantee. Moreover, due to the limitations of the current welding technology level, the brackets and mounting flanges on the exhaust pipe basically cannot be completely wrapped. As long as there are debris entering the vicinity of the engine exhaust pipe, it may cause a fire failure. In addition, some engine manufacturers do not hesitate to increase costs and add exhaust pipe covers to the exhaust pipe, but due to the complex structure of the engine itself, it is also difficult to completely wrap the exhaust pipe with the solution of adding exhaust pipe covers. Summary of the invention

[0005] The technical problem to be solved by the present invention is to provide a tractor exhaust pipe protection structure in view of the deficiencies in the prior art, thereby solving the problem that the current exhaust pipe protection structure is prone to the entry of debris due to incomplete wrapping.

[0006] The technical solution of the present invention is: a tractor exhaust pipe protection structure, including an exhaust pipe metal hard package, an exhaust pipe cover and a soft independent insulation belt; the exhaust pipe metal hard package is sleeved on the exhaust pipe, the exhaust pipe cover is sleeved on the exhaust pipe metal hard package, and the exhaust pipe cover is detachably installed on the exhaust pipe bracket, and the exhaust pipe cover is covered with a soft independent insulation belt for closing the gap between the exhaust pipe and the exhaust pipe cover.

[0007] As a further improvement, the exhaust pipe metal hard package includes a hard package bonding layer, a hard package filling layer, a hard package reflecting layer and a fixing layer which are arranged in sequence; the hard package bonding layer is bonded and connected to the outer wall of the exhaust pipe, and the fixing layer is welded to the exhaust pipe.

[0008] Furthermore, the hard-pack laminating layer is high-silica cloth; the hard-pack filling layer is glass fiber cloth; the hard-pack reflective layer is aluminum-plated fiber cloth; and the fixing layer is a stainless steel embossed plate.

[0009] Furthermore, the thickness of the fixing layer is 0.3 mm-0.6 mm.

[0010] Furthermore, the exhaust pipe cover is mounted on the bracket of the exhaust pipe by means of screws.

[0011] Furthermore, the exhaust pipe cover is provided with a clearance notch and a clearance surface.

[0012] Furthermore, the exhaust pipe cover is a single-layer steel plate with a thickness of 1.0 mm-1.5 mm.

[0013] Furthermore, the soft-pack independent insulation belt is provided with a plurality of clearance holes, one side of the soft-pack independent insulation belt is provided with a groove extending into the clearance hole, the branch pipe of the exhaust pipe is inserted into the clearance hole, and both ends of the soft-pack independent insulation belt are provided with silicone tubes for binding and fixing the soft-pack independent insulation belt.

[0014] Furthermore, an isolation bending belt is provided on the other side of the soft-pack independent insulation belt, and the isolation bending belt overlaps the connection between the engine body and the exhaust pipe cover.

[0015] Beneficial Effects

[0016] The advantages of the present invention are as follows: by protecting the tractor exhaust pipe with the exhaust pipe metal hard package, the exhaust pipe cover and the soft-package independent insulation belt installed on the outside of the exhaust pipe, the heat insulation performance of the exhaust pipe can be greatly improved, and the problem of flammable debris coming into contact with the exhaust pipe and being easily burned can be effectively prevented, thereby ensuring the effective protection of the tractor exhaust pipe, thereby improving the reliability of the tractor engine, and further improving the reliability of the tractor vehicle.

DETAILED DESCRIPTION

[0023] The present invention will be further described below in conjunction with the embodiments, but it does not constitute any limitation to the present invention. Any limited number of modifications made by anyone within the scope of the claims of the present invention are still within the scope of the claims of the present invention.

[0024] See also Figure 1-Figure 5 A tractor exhaust pipe protection structure of the present invention comprises an exhaust pipe metal hard package 1, an exhaust pipe cover 2 and a soft-package independent insulation belt 3. The present invention protects the tractor exhaust pipe through the triple combination of the exhaust pipe metal hard package 1, the exhaust pipe cover 2 and the soft-package independent insulation belt 3, which can greatly improve the heat insulation performance of the exhaust pipe, effectively prevent the problem of flammable debris contacting the exhaust pipe and easily burning, ensure the effective protection of the tractor exhaust pipe, thereby improving the reliability of the tractor engine, and then improve the reliability of the tractor vehicle.

[0025] The exhaust pipe metal hard package 1 is sleeved on the exhaust pipe, and the exhaust pipe metal hard package 1 is fixedly connected to the exhaust pipe. Specifically, the exhaust pipe metal hard package 1 includes a hard package bonding layer 11, a hard package filling layer 12, a hard package reflecting layer 13 and a fixing layer 14 which are sequentially arranged. The hard package bonding layer 11 is bonded to the outer wall of the exhaust pipe, and the fixing layer 14 is spot welded to the exhaust pipe.

[0026] Among them, the hard-pack laminating layer 11 is high-silica cloth. High-silica cloth is directly attached to the surface of high-temperature components, which can improve the reliability and stability of metal wrapping. The hard-pack filling layer 12 is glass fiber cloth, the purpose of which is to increase the insulation thickness, improve the insulation effect and insulation quality. The hard-pack reflective layer 13 is aluminized fiber cloth. Aluminized fiber cloth is a material composited with aluminum foil and glass fiber, in which aluminum foil can achieve high-temperature reflection, and glass fiber has high-temperature resistance. The composite aluminized fiber cloth has good high-temperature resistance and reflection performance. The fixed layer 14 is a stainless steel embossed plate. The thickness of the fixed layer 14 is 0.3mm-0.6mm. More specifically, the fixed layer 14 uses a 0.5mm stainless steel embossed plate. That is, the stainless steel plate is subjected to a rolling pattern post-forming process, and the embossed pattern can play the role of a reinforcing rib and increase the strength of the plate. The stainless steel embossed plate can be designed into one or more pieces according to the shape of the exhaust pipe. If it is designed into multiple pieces, the blocks can be connected by welding. Through the multi-layer composite heat-insulating wrapping technology of the exhaust pipe metal hard package 1, the wrapping coverage of the exhaust pipe can be effectively improved, the exhaust pipe wrapping quality can be improved, and thus the heat insulation performance of the exhaust pipe can be improved.

[0027] In addition, an exhaust pipe cover 2 is sleeved on the exhaust pipe metal hard package 1, and the exhaust pipe cover 2 is detachably mounted on the exhaust pipe bracket 4. Specifically, the exhaust pipe cover 2 is mounted on the exhaust pipe bracket 4 by screws, which can ensure the stable installation of the exhaust pipe cover 2 and reduce the vibration and noise generated by the exhaust pipe cover 2 when the engine is working normally.

[0028] Preferably, the exhaust pipe cover 2 is provided with a clearance notch 21 and a clearance surface 22. The clearance notch 21 and the clearance surface 22 are designed on the exhaust pipe cover 2 to avoid interference objects as needed, thereby ensuring smooth installation of the exhaust pipe cover 2.

[0029] The exhaust pipe cover 2 is a single-layer steel plate with a thickness of 1.0 mm to 1.5 mm. More specifically, the exhaust pipe cover 2 is a single-layer steel plate with a thickness of 1.2 mm, which can be formed by a one-time stamping process. Compared with other complex pipe covers, such as pipe covers with cooling water channels, the exhaust pipe cover 2 of this embodiment has the characteristics of simple structure, strong manufacturability and low cost.

[0030] The soft-pack independent insulation belt 3 is laid on the gap between the exhaust pipe and the exhaust pipe cover 2. The setting of the soft-pack independent insulation belt 3 in this embodiment can not only eliminate the adverse effects of the yield position on the exhaust pipe cover 2 on the exhaust pipe sealing and dust prevention, avoid the contact of debris with the exhaust pipe surface, but also achieve the purpose of heat insulation and improve the heat insulation performance of the exhaust pipe. Specifically, the soft-pack independent insulation belt 3 includes a soft-pack laminating layer, a soft-pack filling layer and a soft-pack reflecting layer arranged in sequence. Among them, the soft-pack laminating layer is laminated on the exhaust pipe cover 2. In addition, the soft-pack laminating layer, the soft-pack filling layer and the soft-pack reflecting layer are high-silicon cloth, glass fiber cloth and aluminum-plated fiber cloth respectively. That is, the soft-pack independent insulation belt 3 in this embodiment is different from the exhaust pipe metal hard package 1 in that the soft-pack independent insulation belt 3 does not have a fixed layer 14. As for the thickness of the laminating layer, filling layer and reflecting layer of the soft-pack independent insulation belt 3 and the exhaust pipe metal hard package 1, they can be adjusted more as needed.

[0031] The soft-packed independent insulation belt 3 of this embodiment is designed according to the covering conditions of the exhaust pipe metal hard pack 1 and the exhaust pipe cover 2. The principle is to cover the exhaust pipe flange and the yield position of the exhaust pipe cover 2 that cannot be completely covered by the exhaust pipe metal hard pack 1. Specifically, a plurality of yield holes 31 are provided on the soft-packed independent insulation belt 3, and a groove 32 extending into the yield hole 31 is provided on one side of the soft-packed independent insulation belt 3, and the branch pipe of the exhaust pipe is inserted into the yield hole 31. When installing the soft-packed independent insulation belt 3, the soft-packed independent insulation belt 3 on both sides of the groove 32 is turned over to make the groove 32 larger, so that the branch pipe can be smoothly inserted into the yield hole 31, which ensures the smooth installation of the soft-packed independent insulation belt 3 and improves the wrapping quality of the protective structure.

[0032] Both ends of the soft-packed independent insulation belt 3 are provided with silicone tubes 33 for tying and fixing the soft-packed independent insulation belt 3. Among them, two high-temperature resistant silicone tubes 33 are provided at each end of the soft-packed independent insulation belt 3. When installing and fixing the soft-packed independent insulation belt 3, the silicone tubes 33 are directly tied and fastened in a suitable position, so that the installation of the soft-packed independent insulation belt 3 can be stable, simple and convenient.

[0033] Preferably, an isolation bending belt 34 is provided on the other side of the soft-pack independent insulation belt 3, and the isolation bending belt 34 overlaps the connection between the engine body 5 and the exhaust pipe cover 2. The isolation bending belt 34 is used to further wrap the exhaust pipe, effectively preventing debris from entering the exhaust pipe cover 2 from the connection between the engine body 5 and the exhaust pipe cover 2.

[0034] The above is only a preferred embodiment of the present invention. It should be pointed out that for those skilled in the art, several modifications and improvements can be made without departing from the structure of the present invention, which will not affect the effect of the implementation of the present invention and the practicality of the patent.
