as shown in fig. 1-2, the boom assembly unit 3 is located on the lift-swing unit 15, and the vertical embedded scraper unit 1 is located at the head of the boom assembly unit 3. When the motor drum assembly 7 works, the lifting-rotating unit 15 moves up and down, and the height of the arm support assembly unit 3 relative to the stacking head surface can be adjusted, so that the material taking head 103 below the vertical buried scraper unit 1 can take materials in the cabin. The embedded scraper ship unloader solves the key problem that the height of a material taking operation surface cannot be adjusted greatly by the existing machine type.

As shown in fig. 3-4, the motor drum assembly 7 is on top of the central cylinder 8 to control the movement of the lift wire 9. The lifting lower pulley 5 is fixed on the lifting platform 1506, and the lifting platform 1506 is sleeved outside the central cylinder 8. The lifting upper pulley 6 is fixed on the top of the central cylinder 8 and below the motor drum assembly 7. The lifting lower pulley 5, the lifting upper pulley 6 and the lifting steel wire rope 9 form a steel wire rope pulley assembly. When the motor drum assembly 7 tightens the lifting wire rope 9, the lifting platform 1506 moves up the central cylinder 8; as the motor spool assembly 7 pays out the lift cable 9, the lift platform 1506 moves downward.

As shown in fig. 7-9, 4 lifting rails 801 are laid around the outer side of the central cylinder 8. The lifting platform 1506 is provided with an upper roller 1503 and a lower roller 1507, each of which is 4 sets. The roller rolls on the lifting track 801 to walk, so that the accuracy and convenience of the lifting platform 1506 moving up and down along the central cylinder 8 under the traction of the lifting steel wire rope 9 can be ensured. According to the actual condition of the ship unloader, the number of the rails and the corresponding rollers can be adjusted.

As shown in fig. 3-4, when the lifting platform 1506 moves up and down along the central cylinder 8, all components directly or indirectly connected to the lifting-turning unit 15, including the vertical embedded scraper unit 1, the boom embedded scraper device 4, the boom assembly unit 3, the balance boom assembly 12, etc. can be lifted. The telescopic chute 20 is fixed on the lifting platform 1506 at the upper part, the lower part is connected with the storage chute 21, and the storage chute 21 is fixed below the central cylinder 8, so that the height of the telescopic chute 20 is changed along with the up-and-down movement of the lifting platform 1506.

As shown in fig. 7-9, the central cylinder 8 is connected to the gantry assembly unit 22 by a slew bearing 25. When the turning mechanism 28 is driven, the center cylinder 8 can rotate around the center of the turning bearing 25, thereby driving the lifting-turning unit 15 to turn. Thus, as shown in fig. 3-4, all associated components on the lift-swing unit 15, including the vertical embedded screed unit 1, the boom embedded screed device 4, the boom assembly unit 3, the balanced boom assembly 12, etc., may swing; the material storage chute 21 is fixedly connected with the lower part of the central cylinder 8 and can rotate along with the central cylinder 8; the telescopic chute 20 is fixed on the lifting platform 1506 at the upper part and connected with the storage chute 21 at the lower part, so that the telescopic chute can also rotate. The rotary feeding device 16 and the gantry scraping device 17 mounted on the gantry assembly unit 22 are not rotatable.

As shown in fig. 3-4, the vertical embedded scraper unit 1 lifts and transfers the materials extracted from the cabin to the cantilever embedded scraper device 4, blanking materials are fed to the portal scraper device 17 through the rotary feeding device 16 by the telescopic chute 20 and the storage chute 21, and the discharging chute 18 discharges the materials to the wharf belt conveyor 19. The telescoping chute 20 can follow the lifting motion of the lifting platform 1506. The material storage chute 21 can reduce the material flow rate and the material breakage rate. In the process, the materials are closed and continuously conveyed, and the ship unloading device has the advantages of no dust leakage, low energy consumption and stable ship unloading efficiency.

As shown in fig. 5 to 6, below the vertical buried scraper unit 1, screw feeders 23 are installed on both sides of the vertical buried scraper extracting head 103. When the vertical buried scraper unit 1 works, the screw heads of the screw feeding device 23 rotate in pairs, so that materials in a warehouse can be stirred, hardening can be broken to improve the flowability of the materials, and enough materials are conveyed for the vertical buried scraper material taking head 103 to ensure the improvement of the productivity of the vertical buried scraper unit 1. The screw feeding driving motor 2301 is arranged above the vertical buried scraper material taking head 103 and far away from a material pile in a warehouse, and the screw feeding device 23 is driven by the screw feeding driving shaft 2302, so that explosion-proof protection can be provided for the screw feeding driving motor 2301, and the safety of ship unloading operation is ensured.

As shown in fig. 11, the boom structure 301 is supported on the lift platform 1506 by a boom hinge point 1502. The vertical buried scraper unit 1 is mounted to the head of the boom structure 301 through a vertical buried scraper swing hinge 102. The pitching pull rod 302 and the pitching support rod 304 are hinged with the arm support structure 301 respectively to form a stable triangle system so as to improve the stress of the arm support structure 301; and provides a pitch link lower hinge point 303 for boom pitch link 10.

As shown in fig. 12, the balanced boom structure 1205 is supported on the lift platform 1506 by a balanced boom hinge point 1505. The upper pivot 1202 of the pitch link connects to the boom pitch link 10 and provides an upper pivot 1201 of the pitch cylinder for the boom pitch cylinder 11. The counterweight 1401 is mounted on a counterweight support 1403, and the lower part of the counterweight support 1403 is connected with a counterweight arm support structure 1205 through a counterweight support lower hinge point 1204. The vertical buried squeegee swing cylinder 13 is supported between the counterweight bracket upper hinge points 1402 and the swing cylinder lower hinge points 1203. The vertical buried scraper swing cylinder 13 stretches and contracts, and the counterweight bracket 1403 can rotate around the counterweight bracket lower hinge point 1204. The adjustable weight balancing structure 14 can balance the weight of the vertical buried scraper unit 1 positioned at the head of the arm support assembly unit 3, so that the synthetic gravity center of all lifting components following the lifting-rotating unit 15 is in the circumference of the central cylinder 8 and approaches the circle center, and the lifting-rotating unit 15 can be prevented from overturning and the working load of all lifting steel wire ropes 9 can be balanced.

As shown in fig. 14, the boom pitch cylinder 11 is supported on the lift platform 1506 through the boom pitch cylinder lower hinge point 1504, and the upper side is hinged to the pitch cylinder upper hinge point 1201. The boom pitching oil cylinder 11 stretches out and draws back, and the balance boom assembly 12 rotates around a balance boom hinge point 1505; simultaneously, the upper hinge point 1202 of the pitching connecting rod drives the pitching connecting rod 10 of the arm support to move, and the lower hinge point 303 of the pitching connecting rod drives the arm support assembly unit 3 to rotate around the hinge point 1502 of the arm support, so that the arm support assembly unit 3 realizes pitching motion. The boom pitching oil cylinder 11 is arranged behind the central cylinder 8 and can be used for weight; and the rear space is large, and the oil cylinders can be reasonably arranged to reduce the working load of the oil cylinders.

As shown in fig. 15, the vertical buried squeegee swing cylinder 13 expands and contracts to drive the rear link 209, the intermediate link 206, and the squeegee link 201 to move. During the movement, as shown in fig. 16, the front swing link 204, the rear swing link 207 and the weight bracket 1403 rotate around the front swing link lower hinge point 205, the rear swing link lower hinge point 208 and the weight bracket lower hinge point 1204, respectively. The squeegee link 201 rotates the vertical squeegee unit 1 about the vertical squeegee swing hinge point 102 to adjust the angle of the vertical squeegee unit 1 relative to the boom assembly unit 3. Because the rotation radiuses of the four parts are identical, the vertical buried scraper unit 1, the front swing link 204, the rear swing link 207 and the counterweight bracket 1403 are always kept parallel. When the vertical buried scraper extracting head 103 swings to the sea side, the counterweight 1401 moves to the land side; when the pick-up head 103 swings to the land side, the weight 1401 moves to the sea side. The position of the counterweight 1401 can be automatically adjusted along with the swing angle of the vertical buried scraper unit 1 so as to reduce the displacement variation of the synthetic gravity center, so that the adjustable counterweight structure 14 has self-adaptive characteristics.

Scene one: as shown in fig. 17, when the dock is at a low water level, the lifting platform 1506 is lowered, the arm support assembly unit 3 is lowered, so that the vertical buried scraper extracting head 103 approaches the working surface, the vertical buried scraper unit 1 swings back and forth, and the vertical buried scraper extracting head 103 covers all working points in the cabin in combination with the rotation of the arm support assembly unit 3, so as to complete the ship unloading operation.

Scene II: as shown in fig. 18, when the ship unloading operation is completed, the lifting platform 1506 is lifted and the arm frame assembly unit 3 is lifted up, so that the vertical buried scraper extracting head 103 is higher than the cabin, and the ship can travel away from the dock.

Scene III: as shown in fig. 19, the cart running device 26 can adjust the position of the ship unloader on the dock so that the vertical buried scraper unit 1 works on the specified cabin. The cooperative operation of a plurality of ship unloaders can be realized by matching with the rotation of the arm support assembly unit 3, so that the whole ship operation efficiency is improved.
