[0020] Such as Figure 1 and Figure 2As shown in the figure, a log turning mechanism includes a support plate 1, a moving frame 2 disposed on the support plate 1 and movable thereon, and a rotating shaft 3 disposed on the moving frame 2 and rotatable thereon. The moving frame 2 includes a vertical plate slidably connected to the support plate 1 through a guide rail slider pair and a horizontal plate disposed on the vertical plate. Claws 4 are symmetrically provided at the lower end of the rotating shaft 3, and the upper end of the claws 4 is rotatably connected to the bottom of the rotating shaft. The two claws 4 are driven to open or clamp by a hydraulic cylinder. When the moving frame 2 moves, the rotating shaft 3 rotates under the action of a linkage mechanism. When the log is conveyed to the position of the claws 4, the claws 4 grab the log, and the moving frame 2 moves leftward, and the rotating shaft 3 rotates synchronously under the action of the linkage mechanism, thereby realizing the turning of the log.
