Abstract

[Problem] The chain may loosen and could cause big loss in power transmission. [Solution] A combine includes: a travelling device (2); a cutting blade (13) for harvesting cereal stems from the farm field; an auger (8) for scraping harvested cereal stems in; a harvesting device (4), provided in front of the travelling device (2) and including the cutting blade (13) and the auger (8); an feeding elevator (14) for feeding harvested cereal stems; a threshing device (3) provided above the travelling device (2) and connected to the harvesting device (4) by means of the feeding elevator (14); an engine (21); a harvesting input shaft (22), provided at the rear end of the feeding elevator (14), to which the rotative power of the engine (21) is transmitted; a first middle shaft (27) provided at the front of the feeding elevator (14) or the rear of the harvesting device (4); a first chain gear (25) attached on the harvesting input shaft (22); a second chain gear (28) attached on the first middle shaft (27); a transmission chain (29) wound about the first chain gear (25) and the second chain gear (28); a second middle shaft (30) provided below the first middle shaft (27); a second gear (32) attached on the second middle shaft (30); a first gear (31) attached on the first middle shaft (27) and engaged with the second gear (32); a rotating shaft (34) provided for the auger (8) and coordinating with the first middle shaft (27); an output member (40) provided on the second middle shaft(30); and a driving-force input member (41) provided for the cutting blade (13) and coordinating with the output member (40).
