Zusammenfassung:	The utility model discloses a piston mechanism with a cross-shaped sleeve structure and relates to the technical field of agricultural machines. The piston mechanism comprises a crankshaft (1), a connecting rod welding-on part (2), a piston welding-on part (6), a cross-shaped sleeve (4), a connecting rod hinge pin (3) and a piston welding-on hinge pin (5). One end of the connecting rod welding-on part (2) is connected with the crankshaft (1), and the other end is connected with the piston welding-on part (6) through the cross-shaped sleeve (4). The connecting rod welding-on part (2) and the cross-shaped sleeve (4) are connected through the connecting rod hinge pin (3). The piston welding-on part (6) and the cross-shaped sleeve (4) are connected through the piston welding-on hinge pin (5). The cross-shaped sleeve (4) is formed by welding a first sleeve (7) and a second sleeve (8). The first sleeve (7) and the second sleeve (8) are arranged in a cross-shaped axis mode. The operation is reliable, the failure rat
