Abstract

The invention relates to a gearbox of a corn combine harvester for spikes and stalks. The gearbox mainly comprises a box body, a power input shaft, a conveying chain I transmission shaft, a conveying chain II transmission shaft, an upper spike picking roll shaft, a lower spike picking roll shaft, a middle transmission shaft, a cutting hobbing cutter shaft and bevel gears and straight gears which are both arranged on the shafts. The power input shaft drives the conveying chain I transmission shaft and the conveying chain II transmission shaft trough meshing of the bevel gears, and drives the upper spike picking roll shaft through meshing of the bevel gears. The upper spike picking roll shaft drives the lower spike picking roll shaft through meshing of the straight gears, the lower spike picking roll shaft drives the middle transmission shaft through meshing of the straight gears, and the middle transmission shaft drives the cutting hobbing cutter shaft through meshing of the straight gears. All gear transmissions happen in the box body so that the gearbox is convenient to lubricate, simple in structure and high in reliability.

Description

technical field [0001] The invention provides a gearbox for a piggyback type corn harvester with both ears and stems, and belongs to the technical field of agricultural machinery. Background technique [0002] Corn has become the largest food crop in my country. The current and future corn harvester market mainly develops corn combine harvesters with low price, simple structure, high reliability and easy maintenance, especially the 2- and 3-row suspension, The self-propelled model mainly completes the functions of ear picking and field returning. The existing knapsack-type corn harvester with ear and stem harvesting has a complex transmission part, the gear transmission is exposed to the outside, the lubrication is not good, and the gears are easily damaged, which seriously affects the reliability of the corn harvester. Contents of the invention [0003] The purpose of the present invention is to provide a backpack type corn harvester gearbox with simple structure and high...
