Driving method for maize harvesting machine

Abstract

The invention discloses a driving method for a maize harvesting machine, which is implemented through separate drive, and a first-path drive directly drives a returning-to-field machine below a power mechanism by a belt. The method is characterized in that a second-path drive is a main drive, and by using a first gearbox, an engine travels respectively through a chain-driven peeling machine, a fringe-cob separating device and a forward travelling wheel; and a third-path drive inputs power into a drive shaft by a double-strand chain, the drive shaft drives in two branches, the first branch drives a lifter to run directly by a double-strand chain driven lifter, the second branch is transmitted to a second gearbox in a header device in a power drive mode, the second gearbox transmits part of the power to a main shaft of a header so as to drive the header to run, and the second gearbox transmits the other part of power to a cut off device, thereby realizing the synchronous running of the header and the cut off device.

Description

technical field [0001] The invention relates to the technology of an agricultural corn harvester, in particular to a transmission method for a corn harvester. Background technique [0002] In most areas of our country, the moisture content of corn grains during harvest is generally 25% to 35%, or even higher, and they cannot be threshed directly during harvest, so the method of harvesting in sections is generally adopted. The first stage of harvesting refers to the direct collection of corn ears after ear picking and straw treatment; the second stage refers to the drying of corn ears in the field or on the field before threshing. [0003] The main structure of the corn harvester includes a walking chassis, a power mechanism and a cab set on the walking chassis, a header and a straw cutting device set in front of the walking chassis, a peeler and an ear box set behind the walking chassis. At present, the transmission methods of corn harvesters often have the following disadv...

AI Technical Summary

Problems solved by technology

At present, the transmission methods of corn harvesters often have the following disadvantages: 1. Usually, the walking wheels, peeling machines, headers and cutting devices are driven by belts. The belt transmission is not only loose in structure, but also has a long transmission chain. 2. The existing transmission mode can only realize the functions of ear picking, ear skin separation, straw cutting, chopping and returning to the field, because there is no special ear separating device and the transmission that drives the ear separating device. structure, and it is impossible to separate the ears of corn from the silk when harvesting, so there are often more corn silks on the harvested ears of corn. In the later accumulation and drying, not only the air-drying efficiency is affected, but the corn silk is very easy to rot. The rot will cause the surrounding corn ears to rot and deteriorate, which will affect the yield; 3. With a single reel chain structure, it is impossible to dial plants with any spacing into the ear picking roller; 4. Due to the peeling process, some grains on the corn ears will Peeled, the traditional machine is that the peeled grains are directly output to the outside together with the purse, but not recycled, resulting in waste
