Abstract

The utility model discloses a green fodder harvester feeding device which drives a hydraulic motor input assembly to work through a hydraulic power output assembly, and the hydraulic motor input assembly and a feeding device power transmission assembly synchronously drive a feeding roller to act. The engine output belt pulley drives a middle shaft belt pulley of the hydraulic power output assembly to rotate through a transmission belt, the middle shaft belt pulley drives the feeding transmission pump to work, and the feeding transmission pump is used for conveying pressure oil needed by work to a transmission motor of the hydraulic motor input assembly. According to the feeding device, the engine is transversely arranged, the main transmission intermediate shaft and the feeding device main driving box body are arranged, so that power hydraulic control output of the engine and fine adjustment of the feeding speed and the cutting length are achieved, the feeding device has the function of fast reverse rotation, and the rotating speed of the transmission motor is increased through transmission of the gear box body; the working pressure, the bearing capacity and the reliability are improved, the requirement for large-feeding-amount feeding is met, and the working efficiency of the machine is improved.
