Grass feeding mechanism of combine harvester

Abstract

The invention provides a grass feeding mechanism of a combine harvester. The grass feeding mechanism comprises a cutting table and a transmitting groove, wherein a rotating shaft support is arranged above the grass feeding opening of the transmitting groove, a rotating shaft is arranged on the rotating shaft support, two fixed bases are arranged on the grass outlet opening of the cutting table, semi-circle groove openings are formed in the fixed bases, shaft heads on the two ends of the rotating shaft are embedded in the semi-circle groove openings of the two fixed bases, a grass feeding arc-shaped board is arranged on the lower edge position of the inner side of the grass feeding opening of the transmitting groove, a rubber cushion is arranged on the outer side of the lower edge of the grass outlet opening of the transmitting groove, an anti-leakage arc-shaped board is arranged on the inner side of the lower edge of the grass outlet opening of the transmitting groove, reversing rolling cylinders are respectively arranged at the grass feeding opening position and the grass outlet opening position inside the transmitting groove, two transmitting chains are arranged between the two reversing rolling cylinders, and a transmitting tooth rake is arranged between the two transmitting chains with equal distance. The grass feeding mechanism can effectively prevent the phenomenon that food leakage occurs at the butt joint of the cutting table and the transmitting groove and has a better application prospect.

Description

technical field [0001] The invention relates to a component of a combine harvester, in particular to a grass feeding mechanism of the combine harvester. Background technique [0002] The grass feeding mechanism of the combine includes the header and the conveying trough, but there is often a problem of grain leakage between the grass inlet of the existing conveying trough and the grass outlet of the cutting platform, and the cutting platform needs to be raised or lowered in real time during the working process. , The conveying trough is also required to be raised and lowered together with the header, and after long-term use, loosening or wear will occur at the joint between the header and the conveying trough. Contents of the invention [0003] The technical problem to be solved by the present invention is that there is a problem of grain leakage at the junction of the header and the conveying trough in the prior art. [0004] In order to solve the above-mentioned technic...
