Abstract

The invention relates to a hydraulic control system for a hydraulic drive cutting table and an elevator. The hydraulic control system comprises an engine, a hydraulic oil tank, a gear pump, a pressure sensor I, a pressure compensation valve I, a controller, a pressure sensor II, a pressure sensor III, a reverse valve I, a hydraulic motor I, the cutting table, the elevator, a hydraulic motor II, a reverse valve II, a pressure compensation valve II and an overflow valve, wherein intelligence of harvester operation is realized through oil path connection and under the control of the controller. The hydraulic control system simplifies a transmission system of a complete machine and improves the working efficiency of the machine.

Description

technical field [0001] The invention relates to a hydraulic control system on agricultural machinery, in particular to a hydraulic control system for hydraulically driving headers and elevators. Background technique [0002] At present, the operation of corn harvester header and elevator is generally driven by mechanical transmission (such as belt drive and chain drive), and it needs to go through multi-stage deceleration to transmit power to the header and elevator. The drive shaft of the drive shaft leads to a complex structure of the transmission device, difficult installation and maintenance, and a high failure rate. Contents of the invention [0003] The purpose of the present invention is to provide a hydraulic control system for a hydraulically driven header and an elevator with a simple transmission system, high working efficiency and certain intelligence. [0004] The technical solution for realizing the object of the present invention is: the present invention c...
