HYDRAULIC SYSTEM OF FULL-HYDRAULIC TRANSPLANTING MACHINE WITH DIFFERENTIAL LOCKING FUNCTION

摘要

relates to a hydraulic system of a fully hydraulically yianggi with a differential lock, the oil tank 15, an oil pump, a plurality of solenoid valves, a plurality of motors, a front wheel drive passage, the rear wheels compose passage and transplanting comprises a flow path, and the front-wheel drive passage is connected to the two-wheel drive motor (1), between the two front wheel drive motor (1) and a synchronization valve (synchronization valve) (3) is installed, the rear-wheel drive passage is connected to the two rear wheel drive motor (2), the two rear wheel drive motor (2) and a synchronization valve (3) it is provided between, between the two output terminals of the synchronous valves 3 Both are connected by one of the on-off valve 21, the flow path is a transplanting transplanting motor 8 and the connection. The hydraulic system has a simple structure and is placed in a convenient, lightweight, weighing and failure is low and maintenance costs, as well as a fully hydraulic yianggi is low on the foundation to develop in the direction equip its versatility. ;
