Description

Technical Field

[0001] The utility model relates to the field of exhaust pipe heat insulation covers, in particular to an agricultural machinery exhaust pipe heat insulation cover which is easy to replace. Background Art

[0002] In agricultural machinery, the main function of the exhaust pipe heat shield is to protect the exhaust pipe and surrounding components and operators from the direct impact and damage of high-temperature exhaust airflow. The exhaust pipe will generate high-temperature exhaust airflow during operation, which may cause damage to surrounding components. The exhaust pipe heat shield effectively isolates and reduces heat transfer by wrapping the exhaust pipe and using insulation materials to prevent heat damage to surrounding components.

[0003] However, the lower heat insulation cover currently on the market cannot meet the use requirements. The heat insulation cover is cast according to the shape of the pipe during manufacturing and can only be installed on pipes of the same shape during installation. There are great limitations on installation on other pipes. In addition, when in use, it is fixed to the upper heat insulation cover by welding, and the pipe is easily damaged when the old heat insulation cover is replaced. Utility Model Content

[0006] A heat shield for an exhaust pipe of agricultural machinery that is easy to replace, comprising a heat shield body, the heat shield body being formed into a cylindrical shape to fit the exhaust pipe, a buckle assembly being arranged on the heat shield body, the buckle assembly comprising a first connector, a spring and a second connector, one end of the spring being fixed to the first connector, the other end of the spring being detachably connected to the second connector, and when the spring is fixed to the second connector, the heat shield forms a cylindrical shape and is attached to the exhaust pipe.

[0007] Optionally, the buckle components are provided in a plurality of groups, and the buckle components in the plurality of groups are spaced apart from each other.

[0008] Optionally, the second connecting member specifically includes a fixing seat, a bolt and a connecting sleeve, the fixing seat is arranged on the surface of the heat insulation cover body, the fixing seat is provided with a threaded hole, the bolt passes through the connecting sleeve, one end of the bolt passes through the connecting sleeve and is threadedly connected to the threaded hole, and one end of the spring is fixed on the connecting sleeve.

[0009] Optionally, the surface of the heat insulation cover is provided with Velcro, and when the heat insulation cover forms a cylindrical shape, the Velcros are attached to each other.

[0010] In summary, the utility model includes the following beneficial technical effects:

[0011] 1. When the heat shield body needs to be put on the exhaust pipe, just pull the spring and screw the bolt at the end of the spring into the threaded hole. When disassembling, just unscrew the bolt. Due to the presence of the spring, the defect of the traditional buckle length being inconvenient to tighten is changed, and the length can be freely adjusted, which is convenient and flexible, and the disassembly efficiency is more efficient.
