Some embodiments of the present invention provide a grain combine harvester. The grain combine harvester includes a vehicle body, a couple of axial flow cylinders, an engine and a transfer case. The couple of axial flow cylinders are mounted on the vehicle body, the couple of axial flow cylinders are adjacent to each other and disposed in parallel, the engine and the transfer case are mounted on the vehicle body respectively, the engine is connected with the transfer case, and the couple of axial flow cylinders are connected with the transfer case respectively. An integrated transmission case and a built-in wet clutch structure are applied to the cylinder transmission, in this way a traditional belt clutch structure is canceled, the transmission is simplified, and the reliability of the whole harvester is improved. A double longitudinal axial flow threshing and separating system is taken, thereby meeting the requirements of threshing and separation of a crop with large feeding quantity. The arrangement of a large harvester product is facilitated, and the feeding quantity of the harvester is improved.

An embodiment of the present invention relates to a cylindrical secondary battery comprising: a cylindrical can having one open end; an electrode assembly received in the can, and wherein a first electrode plate having a first electrode uncoated part, a separator, a second electrode plate having a second electrode uncoated part disposed in a direction opposite to the first electrode uncoated part are stacked and wound into a cylindrical shape; and a cap assembly for closing the open end of the can while the electrode assembly is received in the can, wherein an end of at least one of the first electrode uncoated part and the second electrode uncoated part is bent to form a bending part. An embodiment of the present invention is advantageous for a welding process in that, when a current collection plate is welded, the thickness and number of weldable substrates are increased and the gaps between the substrates are reduced, thereby increasing the heat capacity of a welding part. Furthermore, there are fewer empty spaces between the substrates after the substrates are compacted for welding than a structure having no bending part, and thus the electrode plates or the separator can be prevented from being damaged due to the penetration of welding heat, thereby improving a stability risk.

This application provides an optical module unlocking apparatus, an optical module, and an optical communication device. The optical module unlocking apparatus includes: a housing, including a base and a mounting portion connected to one end of the base, where the base is provided with an accommodation area for installing a circuit board and a component, and the mounting portion is provided with at least one optical port for connecting an optical cable; an unlocking component, including an unlocking arm movably connected to the housing, where the unlocking arm is provided with an abutment portion for abutting against an elastomer of a cage, and the unlocking component is configured to push the unlocking arm outwards relative to the housing in an insertion direction under an action of external force, to separate the abutment portion from the elastomer; and an elastic component, disposed on an outer side surface of the mounting portion and outside the accommodation area, where two ends of the elastic component are respectively connected to the mounting portion and the unlocking component. This can avoid occupying installation space of a circuit structure, increase a volume of the accommodation area, increase an area of the circuit board, increase types and a quantity of components, and improve function diversity of the optical module.
