摘要： A telescopic reel for an agricultural machine includes at least one side module being telescopic relative to a central module for causing the reel to switch from a retracted position to an extended position. A second crosspiece of the side module is adapted to enter into a cavity of a first crosspiece of the central module when the reel is in the retracted position, and is adapted to be extended when the reel is in the extended position. The first crosspiece and the second crosspiece are provided with a crop lifting system. The lifting system includes a connection for connecting lifts to at least one intersection element of the reel so that the lifts can slide along the second crosspiece of the side module. The lifts are brought close to each other when the reel is in the retracted position and the lifts are positioned relative to each other and to the at least one intersection element, at a distance substantially matching that of connection, when the reel is in the extended position.

摘要： A telescopic reel includes a telescopic supporting frame and a central module including at least one bracket constrained to the supporting frame and connectable to a bearing and guide through a fastener. The bearing and guide is adapted to bear and guide, during its rotary motion, at least one transversal intersection element of the reel. The bearing and guide is positioned on the at least one intersection element at a first distance from a longitudinal central shaft of the reel, the first distance being greater than or equal to a second distance between the central shaft and a crosspiece of the reel.

摘要： An agricultural machine for harvesting a crop, which is equipped with a harvesting head, includes: a mowing bar for harvesting the crop; at least one transportation system adapted to transport the crop cut by the mowing bar to a collection mouth of the harvesting head. The at least one transportation system includes: a first transmission system having a first flexible element coupled with a pair of first rotary elements; a second transmission system having a second flexible element coupled with a pair of second rotary elements; at least one arm coupled with both of the first flexible element and the second flexible element, in such a way as to extend on the harvesting head substantially transversally relative to the mowing bar both during a transportation step for transporting the crop cut by the mowing bar and during a return step.
