Abstract: A linear motor achieves both a decrease in pulsation and an increase in propulsion with a 6n teeth structure provided with: a first mover for holding permanent magnets arranged longitudinally; a first stator having 6n teeth that are arranged so as to oppose the first mover and 6n windings that are wound on the respective teeth; a second mover holding permanent magnets longitudinally; a second stator having 6n teeth that are arranged in the longitudinal direction so as to oppose the second mover and 6n windings that are wound on the respective teeth The permanent magnets opposing each other in the first mover and the second mover are disposed with a phase difference of ?/2 in the moving direction of the two movers, and electrical currents with a phase difference of (1+6m)?/3 or (2+6m)?/3 are supplied to the windings opposing each other in the first stator and the second stator.

Abstract: Provided is a threshing cylinder with a threshing processing section provided on the rear side of a raking section. In the threshing processing section, a front support member, an intermediate support member, and a rear support member are supported by a threshing cylinder support shaft. A plurality of front-side divided threshing teeth support members are supported by the front support member and the intermediate support member in a state in which the front-side divided threshing teeth support members are arranged at the same arrangement pitch in the circumferential direction of the threshing processing section. A plurality of rear-side divided threshing teeth support members are supported by the intermediate support member and the rear support member in a state in which the rear-side divided threshing teeth support members are arranged at the same arrangement pitch in the circumferential direction of the threshing processing section.

Abstract: A first threshing section 15 and a second threshing section 16 are provided. The first threshing section 15 includes a first threshing drum 17 that rotates about a left-right-oriented axis, and the second threshing section 16 includes a second threshing drum 28 that rotates about a body front-rear-oriented axis. The second threshing drum 28 includes a rotary support shaft 29 extending along a front-rear direction, a plurality of rod-shaped frame bodies 30 that are arranged side by side extending along the front-rear direction and at and interval in the peripheral direction, radially outward of the rotary support shaft 29, and threshing teeth 31 attached to the frame bodies 30.

Abstract: The threshing apparatus 6 includes a threshing chamber 11 into which the crops are introduced, a threshing drum 12 that is provided in the threshing chamber 11 so as to rotate with the threshing drum axial center in the front-rear direction of the threshing chamber 11 serving as the rotation center, and which threshes the crops introduced into the threshing chamber 11, and a receiving net 13 provided in the outer periphery of the lower part of the threshing drum 12. The receiving net 13 is divided into a plurality of divided receiving net bodies 13A in the front-rear direction, the plurality of divided receiving net bodies 13A are operated to adjust, for each of the plurality of divided receiving net bodies, the interval S in the radial direction of the threshing drum 12 between the divided receiving net body 13A and the threshing drum 12.

Abstract: A combine harvester is provided with left and right main frames that extend in the front-rear direction of a vehicle body, and a threshing device installed between the left and right main frames. The threshing device is provided with a threshing unit that performs a grain removal process, and a sorting unit that is provided below the threshing unit and performs a sorting process of sorting processed articles after the grain removal process has been performed by the threshing unit. A threshing frame included in the threshing unit is mounted on and supported by the left and right main frames, and a sorting unit frame included in the sorting unit is suspended from and supported by the left and right main frames.

Abstract: 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.

Abstract: 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.

Abstract: A combine harvester includes a threshing device 4 configured to perform a threshing process of threshing reaped grain culm in a threshing chamber 23, in which the threshing chamber 23 includes a threshing cylinder 31 configured to rotate around a front-rear axis X, and an arc-shaped receiving net 32 provided extending along an outer circumferential portion of the threshing cylinder 31, and a top plate 30 covering an upper portion of the threshing chamber 23 is supported detachably along the rotation axis direction of the threshing cylinder 31.
