Power transmission system of corn harvester

Abstract

The invention discloses a power transmission system of a corn harvester, wherein the power transmission system comprises a walking power transmission unit and a working power transmission unit arranged on a chassis frame; the walking power transmission unit comprises an engine, a driving axle, a steering axle, a four-wheel-drive gear box and a transmission mechanism; a first output shaft of the engine is connected with the driving axle through a first transmission assembly, the four-wheel-drive gear box is arranged at the bottom of the driving axle, and the output end of the four-wheel-drive gear box is connected with the input end of the steering axle through the transmission mechanism in a transmission manner. The working power transmission unit comprises a cutting table and field returning transmission mechanism, a lifter transmission shaft, a main transmission second shaft, a main transmission first shaft and a peeling machine transmission mechanism; the cutting table and field returning transmission mechanism comprises a transfer case group, filed returning cutter shafts distributed on the bottom of the front side of the transfer case group, a cutting table and field returningvariable speed device distributed below one side of the transfer case group, and a cutting table packing auger shaft distributed behind the transfer case group. The peeling machine transmission mechanism comprises a spike peeling input transverse shaft, a peeling roller shaft group and a spike dialing shaft group.

Description

technical field [0001] The invention relates to a power transmission system of a corn harvester, belonging to the technical field of agricultural machinery. Background technique [0002] With the widespread application of agricultural mechanization equipment, domestic corn harvesting has basically been mechanized. my country has developed corn harvesting machinery by itself for more than 40 years. At present, the product quality and technical content of corn harvesters in my country need to be improved urgently. Many manufacturers simply imitate the prototypes introduced in the early days, so that many models have similarities in harvesting process and structural parameters, repeated manufacturing, lack of reliability, and unreasonable design mechanisms still exist. The power transmission system of the traditional two-row self-propelled corn harvester not only uses sprocket and belt transmission, but also adopts a multi-set gearbox structure, which is complex in structure,...
