[0001] The utility model relates to the technical field of heat insulation equipment, in particular to a heat insulation protection device and a tractor. Background Art

[0002] For non-road agricultural machinery products, the current main supporting power is diesel engines. When the diesel engines are working, the exhaust temperature of the exhaust elbow and connecting components (the pipeline and connection part between the outlet of the supercharger and the muffler or post-treatment) is as high as about 600 °C. Some products of the exhaust elbow have simple heat insulation wrapping, but the heat insulation is not complete, and there are phenomena such as incomplete wrapping or heat transfer.

[0003] For the protection of the existing heat insulation cotton, flat washers are installed on one side or both sides of the heat insulation cotton, and the split pin penetrates through the flat washers and the heat insulation cotton for fixation. When the heat insulation cotton is wrapped around the exhaust elbow with a high temperature, the split pin and the flat washer will contact the exhaust elbow, and the heat will be directly transmitted to the outside, and the temperature of these fixed points will be very high. Due to the complex and changeable operating conditions of agricultural machinery products, when weeds or fluffs come into contact with these high-temperature fixed points, it is easy to cause a fire risk.

The elastic member is a part used to wrap and tighten the heat insulation cotton, and under the action of the elastic member, the overlapping part of the heat insulation cotton can be tightened.

[0045] As Figures 1 to 3 shown, further, one end of the heat insulation mechanism 1 is arranged downward.

[0046] The beneficial effect of adopting the above further technical solution is: the heat insulation cotton adopts an overlapping method. Usually, the outermost part overlaps and then goes downward to ensure that sundries will not enter the overlapping side seams of the heat insulation cotton after falling, so as to ensure the heat insulation effect.

[0047] As Figures 1 to 3 shown, further, the heat insulation mechanism 1 is of an annular structure, and a pair of the hanging members 105 are respectively installed on the outer side walls at both ends of the heat insulation mechanism 1.

[0048] The beneficial effect of adopting the above further technical solution is: the heat insulation mechanism maintains reliable sealing under the pulling force of the elastic member, thereby realizing the heat insulation effect.

[0049] As Figures 1 to 3 shown, further, the hanging part 102 is a split pin.

[0050] The beneficial effects of adopting the above further technical solution are: facilitating the installation and maintenance of the connecting parts and reducing costs.

[0051] As Figures 1 to 3 shown, an embodiment of the present utility model provides a heat insulation and protection device, mainly including: a heat insulation mechanism 1, an exhaust elbow and a connecting part 2. Among them, the heat insulation mechanism 1 mainly includes: an outer heat insulation cotton layer 101, an intermediate heat insulation cotton layer 102, an inner heat insulation cotton layer 103, a heat insulation layer 104 for heat insulation fixing parts, a hanging part 105, a spring (elastic part 106), and a gasket 107.

[0052] The outer heat insulation cotton layer 101 has an outer layer which is a composite layer with beautiful appearance. It can withstand high and low temperatures (-70°C to 700°C), has anti-corrosion, anti-aging, waterproof and oil-proof properties, does not burn at high temperatures, has a low thermal conductivity, and meets the requirements of flame retardancy and fire prevention. Usually, there is also a stainless steel wire mesh on the outermost layer, which can withstand high temperatures (1000°C). Existing products are mostly composed of single materials such as high silica cloth, silica gel cloth, basalt cloth, glass fiber cloth or aluminum foil cloth. After being used for a period of time, the products are prone to breakage. The composite layer adds a stainless steel wire mesh outside the single protective layer to increase the impact strength against external forces and play a protective role. Note: The materials are prior art.

[0053] The intermediate heat insulation cotton layer 102 has good insulation performance, low thermal conductivity, strong heat resistance, good corrosion resistance, high mechanical strength, and can withstand temperatures up to 600°C to 700°C on non-road agricultural machinery, having good heat insulation performance. Usually, there are materials such as glass fiber tape, glass fiber cotton, ceramic fiber cotton, non-woven fiber felt, and high silica needle felt. Different materials and different thicknesses will result in different heat insulation temperatures. Note: The materials are prior art. The selected heat resistance mainly meets the temperature requirements of the whole machine working conditions. Materials within the temperature range of the whole machine working conditions are sufficient. Usually, the whole machine requires -40°C to 700°C.

[0054] The inner heat insulation cotton layer 103 can withstand high and low temperatures (-70°C to 700°C), has anti-corrosion, anti-aging, waterproof and oil-proof properties, does not burn at high temperatures, has a low thermal conductivity, and meets the requirements of flame retardancy and fire prevention.

[0055] The heat insulation layer 104 for heat insulation fixing parts can withstand high and low temperatures (-70°C to 700°C), has anti-corrosion, anti-aging, waterproof and oil-proof properties, does not burn at high temperatures, has a low thermal conductivity, and meets the requirements of flame retardancy and fire prevention.

[0056] The hanging part 105 is a part used to fix on the heat insulation cotton (heat insulation mechanism) and provide a fixed point for the spring. Its characteristics are metal parts, which can be split pins or non-standard metal parts.

[0057] The spring is a part wrapped by heat insulation cotton for tensioning, and under the action of the spring, the lap joint of the heat insulation cotton can be tightened.

[0058] The gasket 107 is used for the fixation between the hanging part 105 and the heat insulation cotton.

[0059] The installation of the heat insulation and protection device is as follows:

[0060] The outer layer 101 of the heat insulation cotton, the middle layer 102 of the heat insulation cotton, and the inner layer 103 of the heat insulation cotton are sewn together at the edges of the heat insulation cotton, and the sewing is tight. The hanging part 105 passes through the gasket 107 and then passes through the outer layer 101 of the heat insulation cotton, the middle layer 102 of the heat insulation cotton, and the inner layer 103 of the heat insulation cotton and then passes through the gasket 107 and then is fixed. The heat insulation layer 104 of the heat insulation cotton fixing part is covered at the position of the hanging part 105 inside the heat insulation cotton. The heat insulation layer 104 of the heat insulation cotton fixing part is sewn again through the edges of the outer layer 101 of the heat insulation cotton, the middle layer 102 of the heat insulation cotton, and the inner layer 103 of the heat insulation cotton. After sewing, the heat insulation layer 104 of the heat insulation cotton fixing part completely insulates the metal part of the hanging part 105 inside the heat insulation cotton. The heat insulation cotton at the heat insulation layer 104 of the heat insulation cotton fixing part is wrapped outside the exhaust elbow and the connecting component 2. Usually, the outermost part is lapped downward. Since there are many overlapping parts after lapping, to save materials, usually the heat insulation layer 104 of the heat insulation cotton fixing part only wraps and insulates the innermost hanging part 105, and the hanging part 105 at the overlapping part after lapping can be without the heat insulation layer 104 of the heat insulation cotton fixing part, which is equivalent to the inside of the outer hanging part 105 being insulated by the overlapping heat insulation cotton. The lapping edge finally faces downward to ensure that sundries will not enter the lapping edge seam of the heat insulation cotton after falling, ensuring the heat insulation effect. After the lapping is tight, it is stretched by a spring, and both ends of the spring are fixed on the hanging part 105. The heat insulation cotton remains reliably sealed under the tensile force of the spring, thus achieving the heat insulation effect. It can effectively protect the high-temperature part of the high-temperature exhaust elbow and the connecting component 2, which can completely solve the problem of incomplete heat insulation of the hanging part 105, avoid the fire risk caused by sundries falling in, improve the reliability of the product, and meet the requirements under special operations.

[0061] The heat insulation of the heat insulation layer 104 of the heat insulation cotton fixing part for the hanging part 105 and the gasket 107 located inside the outer layer 101 of the heat insulation cotton, the middle layer 102 of the heat insulation cotton, and the inner layer 103 of the heat insulation cotton can avoid the contact heat transfer between the hanging part 105 and the gasket 107 and the exhaust elbow and the connecting component 2, playing a role in complete heat insulation.

[0062] The heat insulation cotton adopts a lapping method. Usually, the outermost part is lapped downward to ensure that sundries will not enter the lapping edge seam of the heat insulation cotton after falling, so as to ensure the heat insulation effect.

[0063] In addition, the present utility model further provides a tractor, which includes a heat insulation and protection device as described in any one of the above.

[0064] The beneficial effects of adopting the technical solution of the present utility model are as follows: The heat insulation layer of the heat insulation cotton fixing part completely insulates the metal part of the hitch inside the heat insulation cotton. It avoids the contact heat transfer between the hitch and the exhaust elbow and the connecting components, achieving complete heat insulation. The heat insulation layer of the heat insulation cotton fixing part only wraps and insulates the innermost hitch, saving materials. The heat insulation mechanism maintains reliable sealing under the tension of the elastic component, thereby achieving the heat insulation effect. It can wrap the exhaust elbow and the connecting components, and the fixing points will not come into contact with the high-temperature exhaust elbow and the connecting components, enabling complete heat insulation and protection. In this way, the risk of ignition caused by weeds or floss coming into contact can be avoided, improving the reliability of the product. It can effectively protect against the high temperature of the high-temperature exhaust elbow and the connecting components, avoid the risk of ignition caused by foreign objects falling in, improve the reliability of the product, and meet the requirements under special operations.
