4-tine grapple for bulk loading/unloading

The utility model relates to a four-clack grab bucket for bulk goods loading and unloading, which is provided with a deck beam and a through beam which are provided with assembly pulleys, wherein a guide roller group is fixed on the deck beam which is provided with a lifting lug, and the deck beam is connected with the through beam by the assembly pulleys which pass through the guide roller group and coil about the deck beam and the through beam; four supporting rods are evenly distributed and hinged at the periphery of the deck beam, and a hook-shaped plate of which the upper end is hinged at the periphery of the through beam and the lower end bends inward is hinged at the lower end of each supporting rod; the lower end of the hook-shaped plate is provided with a bucket-shaped grab clack of which the end part is in a 90 DEG sharp angle, and an integrated kettle-shaped bucket body can be formed after the four grab clacks combining inwardly. Because the grab bucket is the four-clack grab bucket, compared with the six-clack grab bucket, the utility model has the advantages that the deadweight is lighter, the bucket capacity is larger, the bucket clacks are reduced, the failure rate is lower, and the maintenance is convenient, and simultaneously, the length of the bucket clack seam is reduced, the sprinkled and leaked phenomena of the goods are lightened, and the grabbing ratio is improved.
