Gear-shifting mechanism of harvester

Abstract

The invention belongs to the technical field of agricultural machinery and particularly relates to a gear-shifting mechanism of a harvester. Against technical problems to be solved, the invention provides the harvester gear-shifting mechanism which is simple in structure, has convenience in gear shifting, is stable, reliable and light and enables people to conveniently obtain structural layout of a machine. In order to solve the technical problems, the invention provides the harvester gear-shifting mechanism which comprises a main tank, a first rotating shaft, a first gear, a second gear, a second rotating shaft, a primary deceleration driven gear, a third-gear driving gear, a third-gear and fourth-gear gear hub ring and a fourth-gear driving gear and the like. The first rotating shaft, the second rotating shaft and a third rotating shaft are arranged in the main tank. The first gear and the second gear are sequentially arranged on the first rotating shaft. The gear-shifting mechanism of the harvester has the advantages of being simple in structure, having convenience in gear shifting, being stable, reliable and light and enabling people to conveniently obtain structural layout of the machine. Top cover type sealing connection is adopted, and gear-selecting and gear-shifting connection layout is convenient.

Description

technical field [0001] The invention belongs to the technical field of agricultural machinery, and in particular relates to a shift mechanism of a harvester. Background technique [0002] The corn harvester is an agricultural machine that uses machinery to complete multiple operations such as picking ears, stacking, and returning the stems to the field at one time when the corn is mature. Technological process: Use a corn harvester to pick ears under the growing state of corn (called standing stalk picking), and under the action of picking rollers and picking plates, the ear stalks are pulled off. Due to the height difference between the inner and outer picking rollers, the ears fall into the ear box, and the ears are opened and stacked after being filled. The high-speed rotating cutter cuts the straw from the root and enters the crushing mechanism to chop it into 3-5cm long pieces, and the straw falls to the ground naturally after chopping. Then the ears are transported t...

Problems solved by technology

[0005] In order to overcome the present invention, the structure of the shift mechanism of the harvester is a handle shift lever, which is often lengthened and bent according to the needs of the structure, which may easily cause insufficient rigidity of the operating shift lever, and it is difficult to enter the gear when shifting and accompanied by the shift lever. The phenomenon of deformation and fracture can not meet the normal shifting work requirements, and brings safety hazards to the operation of the harvester. The technical problem to be solved by the present invention is to provide a simple structure, convenient shifting, stable, reliable, light and Harvester shift mechanism that can facilitate the structural layout of harvesting machinery
