摘要： A threshing apparatus includes: a threshing unit 5; a first sorting unit 11 that is arranged below the threshing unit 5, is driven to reciprocate along the front-rear direction, and threshes processed material from the threshing unit 5; and a second sorting unit 12 that is arranged below the first sorting unit 11, is driven to reciprocate along the front-rear direction, and threshes processed material from the first sorting unit 11. The front end portion of the second sorting unit 12 is provided with a second grain pan 22 that conveys processed material rearward, and the front end portion of the second grain pan 22 is also provided with a wall portion 48 that is higher than the second grain pan 22 in order to be able to prevent processed material from falling forward from the second grain pan 22.

摘要： A combine includes a threshing device and a grain tank that is located above the threshing device and stores threshed grain. A threshing cylinder 31 is located in a threshing chamber and rotates about a front-rear axis, and an arc-shaped receiving net extends along an outer circumferential portion of the threshing cylinder 31. A raking unit 33 is located in a front portion of the threshing cylinder 31 and rakes in reaped culm, and a threshing processing unit 34 is located rearward of the raking unit 33 in the threshing cylinder 31 and threshes the reaped culm. A top plate 30 includes a portion that extends from a location corresponding to an upper portion of the raking unit 33 to a location corresponding to an upper portion of the threshing processing unit 34 and that is removable from a main body portion of the threshing device in a body-rearward direction.
