The device comprises a first material receiving funnel, an upper connecting frame is connected to the upper end of the first material receiving funnel, mounting rods are connected to the left side and the right side of the rear end of the upper connecting frame, a second material receiving funnel is connected to the outer portion of the lower end of the first material receiving funnel in a sleeved mode, and the second material receiving funnel is connected to the lower end of the second material receiving funnel. The lower end of the second material receiving hopper communicates with a first material guiding
barrel, the lower end of the first material guiding
barrel is sleeved with a second material guiding
barrel, the lower side of the exterior of the second material guiding barrel is rotationally connected with a
rocker arm, the interior of the upper end of the first material guiding barrel is connected with a lower connecting frame, and the upper end of the lower connecting frame is arranged in a triangular face mode; the movable
cutting knife and the
cutting rotating ring are arranged at the lower end of the first material receiving funnel, and the
cutting rotating ring is driven to rotate through eccentric motion of the first chain, so that
vinasse is preliminarily
cut; meanwhile, the fixed cutting knife is mounted on the inner wall of the second guide cylinder to secondarily
cut the gliding
vinasse, so that
caking is effectively prevented, and the looseness of the
vinasse is improved.
