Abstract

A combine harvester capable of constructing a robust frame structure for the threshing device is desired. A combine is equipped with a feed chain (10) that supports and conveys the harvested grain, a threshing device (9) that processes the harvested grain conveyed by the feed chain (10) while having a feeder (12), a discharge straw conveying device (13) that is continuously provided at the rear of the threshing device (9) and receives the discharge straw after threshing from the feed chain (10) and supports and conveys it to the rear, and a discharge straw frame (61) that supports the discharge straw conveying device (13). Upper frames (36, 37) that span the front and rear parts of the threshing device (9) are provided on each of the left and right sides at the top of the threshing device (9). The discharge straw frame (61) is provided spanning the upper frame (36) on the left and the upper frame (37) on the right. In addition, a combine is desired that can prevent the discharge straw cutting device from coming into contact with the discharge straw conveying device when switching the discharge straw cutting device between the working position and the non-working position while the discharge straw frame is in a raised state. The combine is equipped with a locking mechanism (130) that regulates the oscillation of the discharge straw cutting device from the working position to the non-working position and from the non-working position to the working position, and an interlocking mechanism (137) that links the regulating operation of the locking mechanism (130) with the rising operation of the discharge straw frame (61). The interlocking mechanism (137) has an arm (138) that can oscillate independently of the discharge straw frame (61) around a front-rear axis (Y2), an action member (139) that moves integrally with the discharge straw frame (61) and presses against the arm (138), and a linking member (140) that links the arm (138) and the locking mechanism (130). In addition, a combine is desired that can prevent the discharge straw conveying device from coming into contact with the discharge straw cutting device by the rising of the discharge straw frame. The drive control unit (1060) can raise the discharge straw frame to a first rising position by the actuator (1039) when the position determination unit (1061) determines that the discharge straw cutting device is located in either a working position or a non-working position, and when the position determination unit (1061) determines that the discharge straw cutting device is not located in either a working position or a non-working position, the discharge straw frame can only be raised to a second rising position lower than the first rising position by the actuator (1039).
