The invention discloses a hydraulic control system and method for an automatic tensioning device of a crawler belt of a cotton picker and the cotton picker, the pressure of a rodless cavity of a hydraulic oil cylinder is detected in real time through a pressure sensor, and the working state of a control valve group is controlled according to a pressure detection result. The control valve set drives the hydraulic oil cylinder to stretch out so as to increase the tensioning force of the crawler belt or drives the hydraulic oil cylinder to retract so as to reduce the tensioning force of the crawler belt, so that the tensioning force of the crawler belt can be automatically adjusted, and compared with an existing spring tensioning mode, the pre-tensioning force of the spring does not need to be manually and frequently adjusted; the tensioning force of the crawler belt can be automatically adjusted according to actual working conditions in the cotton harvesting operation process, so that the crawler belt is always kept in a tensioning state in the operation process, and the automation degree is high.

    本发明公开了一种采棉机履带自动张紧装置的液压控制系统及方法、采棉机,其通过压力传感器实时检测液压油缸的无杆腔压力,并根据压力检测结果控制控制阀组的工作状态,使得控制阀组驱动液压油缸伸出以增大履带张紧力或驱动液压油缸缩回以减小履带张紧力,从而可以实现履带张紧力的自动调节,相比于现有的弹簧张紧方式而言,无需人工频繁调整弹簧的预张紧力,可以在棉花采收作业过程中根据实际工况自动调节履带张紧力大小,使得履带在作业过程始终保持张紧状态,自动化程度高。
