[0001] The utility model relates to the technical field of generators, in particular to an energy-saving generator assembly for agricultural vehicles. Background Technique

[0002] A generator refers to a mechanical device that converts other forms of energy into electrical energy. It is driven by a water turbine, steam turbine, diesel engine or other power machinery, and converts the energy generated by water flow, air flow, fuel combustion or nuclear fission into mechanical energy and transmits it to the generator, which then converts it into electrical energy; an agricultural vehicle generator refers to using an agricultural vehicle to drive the generator to work through energy sources such as diesel, converting chemical energy into electrical energy, and then meeting the power consumption needs of the agricultural vehicle itself.

Use the power generation drive motor 2 to drive the driving pulley 6 to rotate. Under the action of the driving pulley 6 and the driving belt 8, drive the driven pulley 7 to rotate, and then realize the power generation operation through the generator 5. Under the action of the support spring 22, push the lower abutting frame 13 and the abutting pipe to apply a certain upward force to the driving belt 8, and then cooperate with the driving pulley 6 and the driven pulley 7 to realize the tensioning of the driving belt 8, effectively avoiding the problem of the driving belt 8 loosening after long-term use, ensuring the efficient transmission between the power generation drive motor 2 and the generator 5 in the device, reducing the risk of belt slipping and energy damage, and achieving the purpose of energy conservation.

When using the abutting roller 14 inside the lower abutting frame 13 to tension the driving belt 8, use the first pressure sensor 19 to detect the tensioning state of the driving belt 8 in real time. When the tension is insufficient or the tensioning mechanism 9 fails, the alarm device can be used to timely remind the operator to perform corresponding processing to ensure the safe operation of the equipment. When the driving belt 8 is loose, it can work normally under the action of the tensioning mechanism 9. When the driving belt 8 contacts the rotating rod 28, the second pressure sensor 29 detects the pressure change. At this time, the driving belt 8 reaches the scrapped state, and the alarm operation is realized through the controller and the alarm device to remind the staff to replace the driving belt 8.
