The invention provides an automatic tensioning system and method for crawler walking of a sugarcane harvester. The automatic tensioning system comprises a guide wheel, a tensioning mechanism, a pressure sensor, an electromagnetic control valve, an oil inlet pipe, an oil return pipe, an oil pump and an oil tank. The fixed end of the tensioning mechanism is connected with the track beam, the free end of the tensioning mechanism is connected with the guide wheel, the guide wheel is matched with the track assembly, the electromagnetic control valve is connected with a grease system of the tensioning mechanism and connected with the oil inlet pipe and the oil return pipe, and the oil inlet pipe and the oil return pipe are both communicated with the oil tank. The pressure sensor is arranged in the tensioning mechanism to obtain oil pressure signals of the tensioning mechanism and is in electric signal connection with the electromagnetic control valve, and the oil pump is arranged between the oil inlet pipe and a pipeline of the oil tank and is in electric signal connection with the electromagnetic control valve. The pressure value of the oil cavity of the tensioning mechanism can be set according to different working conditions, the crawler belt is adjusted to be in the most suitable working state, and the set oil cavity pressure can be kept all the time in the working process.

    本发明提供一种用于甘蔗收获机履带行走自动张紧系统及履带自动张紧方法,包括引导轮、张紧机构、压力传感器、电磁控制阀、进油管、回油管、油泵和油箱;张紧机构的固定端连接履带梁,张紧机构的自由端连接引导轮,引导轮和履带总成配合,电磁控制阀连接张紧机构的油脂系统,电磁控制阀连接进油管和回油管,进油管和回油管均连通油箱,压力传感器设置在张紧机构内获取张紧机构的油压信号,压力传感器和电磁控制阀电信号连接,油泵设置在进油管和油箱的管路之间,油泵和电磁控制阀电信号连接。本发明可以根据不同工况条件设置张紧机构油腔压力值,将履带调整到最适合工作的状态,工作过程中能时刻保持设定的油腔压力。
