The invention provides a full-hydraulic four-wheel steering system for a cotton picker. The full-hydraulic four-wheel steering system comprises a carbon steel oil tank, an oil filter, a steering pump,a steering gear, a front steering oil cylinder, a two-position two-way electromagnetic valve, a two-position two-way electromagnetic valve, a two-position four-way electromagnetic valve, a rear steering oil cylinder and an oil-returning oil tank. The system is reasonable in structural design and flexible to operate; the electromagnetic valves can be controlled to be powered on according to systemrequirements, so front wheel steering and synchronous four-wheel steering of the cotton picker are achieved; and the steering system has the advantages of being small in turning radius, low in cost,high in reliability, convenient to maintain and repair, suitable for operation of the cotton picker under severe working conditions in centralized farming time, and capable of reducing the productionand maintenance cost of the cotton picker.

    本发明提供了一种采棉机用全液压四轮转向系统,包括碳钢油箱、滤油器、转向泵、转向器、前转向油缸、二位二通电磁阀、二位二通电磁阀、二位四通电磁阀、后转向油缸、回油油箱。该结构设计合理,操作灵活,能够根据系统需求控制电磁阀得电,从而实现采棉机的前轮转向和同步四轮转向,具有较小的转弯半径,同时具备较低的成本和较高的可靠性,维修维护方便,适用于工作条件较恶劣、农时较集中的采棉机作业,降低采棉机生产、维修成本。
