Abstract

The invention belongs to the technical field of agricultural machinery, and particularly relates to a hydraulic main clutch mechanism of a corn harvester. The hydraulic main clutch mechanism comprises a storage box, a tensioning wheel assembly, a pull rod, a reset spring, an engine belt wheel, a main transmission belt wheel, a transmission belt, a safety switch, a main clutch oil cylinder, a clutch rocker arm, a first oil pipe, a second oil pipe, a high-pressure valve and a hydraulic oil tank, the tensioning wheel assembly is arranged in the storage box, the front end of the tensioning wheel assembly is fixedly connected with the pull rod, the rear end of the lower portion of the pull rod is rotationally connected with the inner wall of the storage box through a bolt, the periphery of the surface of the main transmission belt wheel is rotationally connected with the transmission belt, a set of hydraulic elements are controlled through a control handle, and large force can be controlled through small control force, the problem that the operating force is too large or the stroke is too long in the combining and separating process of the corn harvester is solved, and the tensioning force of a main clutch transmission belt can better meet the use requirement. The labor intensity of operators is effectively reduced, the transmission efficiency of the transmission belt is improved, and the service life of the transmission belt is prolonged.

Description

technical field [0001] The invention belongs to the technical field of agricultural machinery, in particular to a hydraulic main clutch mechanism of a corn harvester. Background technique [0002] At present, the main clutch mechanism of the corn harvester developed in the domestic market adopts the transmission belt tensioning method. This kind of mechanism mainly uses the pull rod to pull the tensioner pulley and press the outer surface of the transmission belt to make the main transmission mechanism run so as to drive such as cutting platform, elevator, etc. machine, peeling machine, chopping and returning to the field mechanism, etc. Although this mechanism is simple and practical, it has certain defects: first, this mechanism uses a pull rod to pull the tensioner pulley to forcefully press the transmission belt, and the main clutch is mechanically manipulated. Limited by the stroke of the pull rod, a large force is required to operate the main clutch mechanism, resulti...
