Abstract
A combine includes a sorter 2B including a sieve case 23 drivable to swing; a first chaff sieve 27 held by the sieve case 23 and configured to receive a processing target falling through a receiver net 8 and sort the processing target; a second chaff sieve 28 held by the sieve case 23 in such a manner as to coincide with the first chaff sieve 27 in the front-back direction relative to the sorter 2B and configured to receive a processing target falling through the first chaff sieve 27 and sort the processing target; and a winnowing fan 29 configured to blow sorting air along the first and second chaff sieves 27 and 28.
Claims8
A combine, comprising:
- a reaper configured to reap a crop planted in an agricultural field;
- and
- a thresher device comprising:
- a thresher chamber configured to receive the whole reaped crop that the reaper has reaped;
- a thresher cylinder disposed rotatably in the thresher chamber and configured to thresh the reaped crop that the thresher chamber has received;
- a receiver net below the thresher cylinder;
- and
- a sorter configured to sort a processing target falling through the receiver net,
- the thresher cylinder comprising:
- a thresher cylinder shaft disposed rotatably in the thresher chamber and extending in a front-back direction relative to the thresher chamber;
- a plurality of bar-shaped thresher teeth supports held by and extending along the thresher cylinder shaft and apart from one another in a circumferential direction of the thresher cylinder;
- and
- a plurality of bar-shaped thresher teeth provided for and held by each of the plurality of thresher teeth supports, protruding from the thresher teeth support outward in a radial direction of the thresher cylinder, and apart from one another along the thresher cylinder shaft, and
- the sorter comprising:
- a sieve case disposed below the receiver net and drivable to swing;
- a first chaff sieve held inside the sieve case and configured to receive the processing target falling through the receiver net and sort the processing target while conveying the processing target backward relative to the sorter;
- a second chaff sieve held by the sieve case in such a manner as to coincide with the first chaff sieve in a front-back direction relative to the sorter and be below the first chaff sieve and configured to receive the processing target falling through the first chaff sieve and sort the processing target while conveying the processing target backward relative to the sorter;
- and
- a winnowing fan disposed at a front portion of the sorter and configured to blow sorting air backward relative to the sorter along the first and second chaff sieves.
