Main transmission system for cutting table of corn machine

Abstract

The invention discloses a main transmission system for a cutting table of a corn machine. The main transmission system comprises an engine assembly, a total output shaft assembly, a cutting table input shaft assembly, a front cutting assembly, a first transmission belt, a second transmission belt, a third transmission belt, a transmission chain and a cutting table assembly, wherein the total output shaft assembly, the cutting table input shaft assembly and the front cutting assembly are mounted on a chassis assembly; the total output shaft assembly is connected with a clutch of the engine assembly through the first transmission belt; the cutting table input shaft assembly is connected with the total output shaft assembly through the second transmission belt; the cutting table assembly is connected with a right transition shaft assembly of the cutting table assembly through the transmission chain; and the right transition shaft assembly is connected with the front cutting assembly through the third transmission shaft. The main transmission system has the advantages that main transmission of a cutting table is usually realized through a belt, so that the main transmission system is reliable in structure, low in cost and easy to mount and adjust; welding of a bracket on the right side of the cutting table is realized through postwelding machining, so that the coaxiality of mounting holes of a bearing seat is high, the coaxiality of two deep groove ball bearings is adequately guaranteed, and the stress is balanced; and by utilizing the deep groove ball bearings, the structure is reliable, and the cost is substantially lowered.

Description

technical field [0001] The invention relates to a transmission system, in particular to a main transmission system of a corn machine header. Background technique [0002] Corn is the main food crop in my country, with a planting area of ​​about 300 million mu. In recent years, with the continuous advancement of the national agricultural machinery subsidy policy, the machine harvest rate of corn is also increasing year by year, and the labor intensity of labor is decreasing year by year. As the key part of the corn machine, the header is of great importance in its transmission efficiency and reliability. At present, the main transmission of corn machine headers on the market is mainly chain, which is noisy, high in cost, difficult to lubricate and adjust, high in failure rate, and short in service life. In addition, outer spherical ball bearings are mostly used for transmission shaft bearings, which are costly, difficult to lubricate and maintain, and have a short service l...
