Abstract

The invention discloses a main clutch electrically controlled hydraulic operation mechanism for a harvester. The main clutch electrically controlled hydraulic operation mechanism comprises a main clutch, wherein a rotating arm which realizes combination and separation of the main clutch is connected with a piston of a main clutch oil cylinder through a connection device; the connection device comprises a rotating arm connection fork and a middle connection piece which are connected with each other; an opening in which the rotating arm is inserted is formed in a fork head at one end of the rotating arm connection fork, and opposite long holes are respectively formed in side plates on two sides of the opening; the end part of the rotating arm can move in the long holes through pin shafts; a tension spring is arranged on the main clutch oil cylinder; two ends of the tension spring are respectively connected with a cylinder body and the piston of the main clutch oil cylinder; a combination electrical control switch and a separation electrical control switch are respectively arranged at two ends of the rotating arm in a rotating travel; an electrical control button is arranged in a cab; the electrical control button is connected with an electromagnetic reversing valve in a hydraulic control loop for controlling the main clutch oil cylinder; a uni-directional throttling valve is arranged between the electromagnetic reversing valve and the main clutch oil cylinder. The main clutch electrically controlled hydraulic operation mechanism for the harvester simplifies connection pieces of the whole machine, improves the part reliability and greatly reduces the labor intensity of a driver.

Description

technical field [0001] The invention relates to the technical field of agricultural machinery, in particular to an electronically controlled hydraulic control mechanism for a main clutch of a harvester. Background technique [0002] At present, the main clutch assembly has been widely used in power output devices on harvesters in my country. The main clutch assembly is connected to the harvester engine and controls the coupling or separation of the clutch by manipulating the rotation of the rotating arm. There is a self-locking point in the rotation stroke of the clutch arm. After turning over the self-locking point, there is no need to operate, and the arm will automatically turn forward and then a certain angle. At this time, the friction plate has been compressed and the clutch is in the combined position; pull back After moving the rotating arm, after passing the self-locking point, the rotating arm will automatically bounce off, the friction plate is released, and the c...
