[0030] The sliding plate 176 moves up and down to drive the rotating rod 181 to move up and down, and the rotating rod 181 moves up and down to drive the short plate 182 and the gear 183 to move up and down. The gear 183 contacts the rack 184 during the up and down movement, so that the gear 183 is blocked by the rack 184 during the up and down movement, and then the gear 183 rotates. The rotation of the gear 183 drives the rotating rod 181 and the short plate 182 to rotate. The short plate 182 rotates inside the feed frame 14, which effectively prevents the grain from being stuck between the feed frames 14, thereby improving the conveying efficiency. When the sliding plate 176 moves upward, it will drive the square plate 185 to move upward. The square plate 185 moving upward will block the guide plate 186. By intermittently blocking the guide plate 186, it can prevent too much food from entering and causing equipment failure. At the same time, the rotation of the short plate 182 will push the triangular block 188 to move downward. The downward movement of the triangular block 188 will drive the dredging plate 189 to move downward. The dredging plate 189 moves downward to dredge the bottom of the feed frame 14 to prevent the food from blocking the space between the feed frame 14 and the feed pipe 4, affecting the conveying effect.
