The utility model relates to the technical field of stackers, in particular to an anti-falling mechanism of a
straw stacker, which comprises a frame, a stacking mechanism is arranged on the frame and used for grabbing and stacking
straw bundles, and the stacking mechanism comprises a moving component, a lifting component, a lifting component, a lifting component and a lifting component, the grabbing
assembly comprises a mounting plate arranged on the moving
assembly, a transverse frame is fixed to the bottom of the mounting plate, shaft frames are fixed to the two ends of the transverse frame, shaft rods are rotationally installed at the lower ends of the shaft frames, swing arms are fixed to the two ends of each shaft rod, a connecting plate is fixed between the two swing arms, and a plurality of grabbing hooks are fixed to the lower end of the connecting plate; the anti-falling
assembly comprises a transmission gear rotationally installed in the middle of the outer wall of the connecting plate, a guide rail is fixed to the outer wall of the connecting plate, and sliding frames are slidably installed at the two ends of the guide rail; and the displacement of the
straw bundles in the front-back direction is effectively restrained through the anti-falling assembly, the problem that materials slide down in the front-back direction under the
inertia effect of a traditional stacking
machine is solved, the grabbing requirements of the straw bundles of different sizes can be met, and universality is improved.
