Title:
HYDRAULIC APPARATUS
Document Type and Number:
Japanese Patent JPS5817201
Kind Code:
A
Abstract:
PURPOSE:To provide a hydraulic apparatus of a harvesting machine having a hydraulic circuit which is simplified by providing a control circuit of a solenoid valve where operational priority can be compulsorily reversed. CONSTITUTION:When a machine advances biasing right of left relative to a grain culm, a solenoid Se or Sr is intermittently excited. While the directing solenoid Se or Sr is excited, hackling depth adjusting solenoid Sh or Sm is not excited, so that a solenoid valve V2 is located at a neutral position, and directing hydraulic cylinder Ce or Cr is driven so that a side clutch 5e or 5r is off state to stop the drive of a left or right 50e or 50r, whereby the running direction of the machine is corrected toward the left or right. On the contrary, while the solenoid Se or Sr is demagnetized, the solenoid Sh or Sm is excited so that pressure oil is supplied to the cylinder C2 so as to cause a longitudinal conveying chain 41 to erect or incline to the deep hackling side or shallow hacling side.
