The invention relates to the technical field of combine harvester transformation, in particular to a crawler-type combine harvester hydraulic steering system transformation method. On the basis that an original manual steering system is not changed, an electronically controlled hydraulic steering system is additionally arranged; the electronically controlled hydraulic steering system comprises a hydraulic part and a circuit part and is connected with a steering execution mechanism of the original steering system, automatic navigation of a crawler-type combine harvester can be achieved after navigation equipment is connected, and the turning radius is adjustable; when automatic navigation has deviations, the direction of the harvester can be manually adjusted at any time without conflicting with automatic navigation; when the automatic navigation system is not used, the original system can still be used for manually operating steering. According to the crawler-type combine harvester hydraulic steering system transformation method, on the premise that the original steering system is not changed, manual and automatic integrated steering system transformation is conducted, the transformed steering system can not only manually operate steering but also automatically navigate steering, and a very good market value is achieved.
Description
technical field [0001] The invention relates to the technical field of refitting a combine harvester, in particular to a method for refitting a hydraulic steering system of a crawler combine harvester. Background technique [0002] Since the 21st century, driven by biotechnology and information technology, "precision agriculture" with the core of improving the utilization rate of agricultural resources and protecting the agricultural ecological environment has developed rapidly. As a core key technology of precision agriculture, automatic navigation of agricultural machinery is widely used in agricultural production processes such as farming, sowing, fertilizing, spraying, and harvesting. Among them, the automatic navigation of the combine harvester is an important way to realize the intelligence, efficiency and precision of the harvesting operation. The application of combine harvester automatic navigation can optimize the harvesting path, reduce repeated operation areas, ...
