Threshing equipment and harvesting machinery for harvesting machines

Abstract

To provide a threshing device and harvesting machine for harvesting machinery that are less likely to inhibit the reduction of secondary crops. [Solution] The threshing device 43 of the harvesting machine comprises a threshing unit 430, a sorting unit 44, a return unit, and a return sensor 1. The threshing unit 430 has a threshing drum 432 and a receiving net 431 positioned below the threshing drum 432, and performs threshing. The sorting unit 44 performs sorting on the threshed grain. The return unit returns a portion of the threshed grain as second-grade material from the downstream side of the sorting unit 44 to the upstream side of the sorting unit 44. The return sensor 1 detects the amount of second-grade material returned from the second-grade return port 445 of the return unit. The return sensor 1 is supported by a support member 11 of the receiving net 431 and is positioned opposite the second-grade return port 445. The return sensor 1 detects the amount of return based on the impact on a non-movable detection unit 101.

Claims
