Combine harvester

Abstract

Provided is a combine harvester that improves the transport performance of grain stalks. This combine harvester comprises: a feeder 24 that transports grain stalks backward from a feeder inlet 240a; an auger 23 that collects, at the feeder inlet 240a, grain stalks from a field, the grain stalks having been cut by a cutter 22; and a backflow prevention plate 25 that covers a portion of the feeder inlet 240a and prevents the grain stalks from returning to the auger 23 from the feeder inlet 240a.

Description

technical field [0001] The invention relates to a combine harvester. Background technique [0002] For example, as shown in Patent Document 1, a combine harvester is known, which has: a harvesting unit that harvests the ear stalks of the field; and a feeder that transports the ear stalks harvested by the harvesting unit to the rear. . The harvesting unit has: a cutter for cutting the fringe stalk; and an auger for collecting the fringe stalk cut by the cutter to the inlet of the feeding part. The feeder has: a feeder chamber in which an inlet of the feeder is formed; and a conveyor arranged in the feeder chamber and reciprocating in the front-rear direction. [0003] Although the conveyor conveys the ear stalks from the front to the rear, a part of the ear stalks may attach to the conveyor and return from the rear to the front. When the fringe stalks are returned, when the conveyor turns back at the front end of the conveyor, the adhering fringe stalks may be fed by the a...

AI Technical Summary

Problems solved by technology

Then, the fringe stalk may be wound around the auger, and the feed function of the auger as a feed screw may be impaired, resulting in a decrease in conveying performance.
