Description
Technical Field
[0001] The utility model relates to the technical field of traction devices for agricultural machinery, and more specifically, to a traction device for agricultural machinery. Background Art
[0002] In the field of agricultural machinery, traction devices are key components that connect tractors to various agricultural machinery. They need to be able to withstand harsh field environments while ensuring the stability and safety of the connection. However, existing traction devices for agricultural machinery have some problems in design and use, which may affect the performance and reliability of the traction devices.
[0003] First of all, many existing traction devices use a simple plug-in rod to connect the tractor and agricultural machinery. This design may be sufficient for use on flat roads or simple working environments, but once encountering bumpy roads or complex field conditions, this simple connection method may not be sufficient to maintain stability. The pin is prone to slipping out due to vibration in this connection method, resulting in disconnection, which not only affects the continuity of the operation, but may also cause damage to the equipment. At the same time, some existing traction devices use a limiting structure to enhance the stability of the connection. However, this limiting structure may appear cumbersome in actual operation and require complicated disassembly and assembly steps, which not only increases the difficulty of operation but also reduces work efficiency.
[0004] In addition, the existing traction device does not have a special placement mechanism when the pin is pulled out, which may cause the pin to be lost during use, especially in field operations. Once the pin is lost, it is difficult to find it in a complex field environment, which will undoubtedly cause inconvenience to the operation and may even affect the entire operation process.
