The swing buried scraper feed chute 1701 is connected to the boom scraper discharge chute 2102. The rotary chute feed chute 1101 is connected to a swing buried scraper conveyor discharge chute 1703.

One side of the door frame 12 is provided with a cable reel 25, and the other side is provided with a high-voltage electrical room 26; the cart 13 travels along the quay line.

The specific implementation process comprises the following steps:

The travelling trolley track 180403 of the trolley 20 carrying the vertical buried scraper reclaiming arm 19 is outside the two main arm frames 180402, and the trolley 20 is hung on the main arm frames 180402 in a hanging way; the double-layer arm support unit 18 can be lifted according to the water level and the ship condition, so that the walking height of the trolley is always close to the hatch, the lifting height of materials during ship unloading operation is reduced, and the efficiency and the energy consumption are high. The inner side of the truss type upright post 5 can be provided with an arm support lifting pulley mechanism 6, an arm support lifting steel wire rope 4, a material taking head lifting pulley mechanism 3 and a material taking head lifting steel wire rope 7, so that mechanisms in a machine room positioned behind the land side can realize control of a vertical buried scraper material taking arm 19 and a double-layer arm support unit 18; the on-board material conveying mechanism can adapt to the change of the relative position caused by the lifting of the double-layer arm support unit, and the materials are continuously conveyed and smoothly transferred. The ship unloader model solves the key problem that the material conveying mechanism and the mechanism of the trolley propelling type continuous ship unloader are difficult to arrange, and has the advantages of reasonable structure, environment-friendly operation, energy conservation and high efficiency.

The arm support lifting mechanism 9 controls the arm support lifting steel wire rope 4 to move. The boom lifting steel wire rope 4 enables the double-layer boom unit 18 to perform lifting motion along the truss type upright 5 through the boom lifting pulley mechanism 6 arranged on the truss type upright 5 and the double-layer boom unit 18 so as to adjust the height of the main boom assembly 1804, and the number of the large pull rods 1801 can be increased or decreased according to the length of the main boom assembly 1804. The two main arms 180402 provide an unobstructed space between the large tie rods 1801 for the placement of the continuous conveyor mechanism and for the travel path of the cart 20 with the vertical buried screed take out arm 19.

The horizontal wheels 2004 roll along the outside of the two trolley rails 180403, ensuring the horizontal position between the trolley 20 and the main arm 180402; the trolley counter roller 2002 rolls against the counter roller track 180405 to prevent upward lift forces from disengaging the wheels 2001 from the trolley track 180403 during operation of the vertical buried scraper reclaiming arm 19.

The vertical arm 180210 is connected to the main arm 180402 by a main arm frame hinge 1806, and the stiffener 180208 adds horizontal support to the vertical arm 180210 to reduce bending moments at the connection of the vertical arm 180210 to the guide arm frame 180201. The upper cross beam 180203, the front pull rod 180202, the guide arm support rear pull rod 180205, the support frame 180204 and the guide arm support 180201 together form a stable structural system to bear the load of the main arm support assembly 1804 and the balance arm support assembly 1807. The guide arm support 180201 and the guide rack 180206 are respectively provided with 4 groups of guide rollers 180207, see fig. 11 and 12. Referring to fig. 18, truss type column 5 is composed of 4 columns 502 and tie bars 503. The outer side of the upright post 502 is welded with a boom lifting rail 501. Referring to fig. 19, the guide roller 180207 abuts against the boom lifting rail 501 from the outside to limit the horizontal displacement of the guide boom 180201, and ensure the relative position between the double-deck boom unit 18 and the truss-like upright 5. When the double-layer arm support unit 18 lifts along the truss type upright post 5, the guide rollers 180207 roll along the arm support lifting track 501, so that friction force can be reduced, and lifting movement is flexible. In fig. 12, the guide 180206 is opened at the front to reserve a space required for movement of the swing scraper conveyor 21, see fig. 29.

The balancing weight 180704 is located at the tail of the balancing boom 180702, and can balance the weights of the trolley 20, the vertical buried scraper extracting arm 19 and the main boom assembly 1804, so that the combined gravity centers of the double-layer boom unit 18 and all lifting components located on the double-layer boom unit are located between 4 upright posts 502 of the truss type upright posts 5, and the boom lifting steel wire ropes 4 between all truss type upright posts 5 and the double-layer boom unit 18 are guaranteed to bear tensile force at the same time.

The truss type column 5 is supported on the gantry mechanism 12 through a large slewing bearing 27. The cab 28 is positioned below the truss-like upright 5 and is offset to one side so that the operator can observe the operation of the vertical buried scraper reclaiming arm 19. The low-voltage electric room 23 is positioned at both sides of the lower part of the truss type upright 5. When the slewing mechanism 24 drives, the truss type upright 5 can drive the double-deck boom unit 18 and all the components located thereon to rotate together around the slewing center of the whole crane, so that the double-deck boom unit 18 is parallel to the quay line, as shown in fig. 32. Under non-operating conditions, the vertical buried screed reclaiming arm 19 may be set aside and serviced on a dock. Under the truss type column 5, 4 columns 501 leave a space in the front-rear direction. When the double-deck arm support unit 18 is lifted, the rotary chute 11 and the swing embedded scraper 17 can move in the space, as shown in fig. 29 and 30.

The cable reel 25 and the high voltage electrical room 26 are arranged on two sides of the portal frame so as to lower the center of gravity of the whole machine. The cart 13 walks along the quay line, and the operation position of the whole machine on the quay can be adjusted.

The arm support lifting mechanism 9 and the material taking arm lifting mechanism 10 are positioned below the truss type upright post 5 and at the land side in the machine room 8 for balance reuse. The purpose is to make the center of gravity of all the turning parts lie in the diameter of the turning large bearing 27, so as to reduce the load of the turning large bearing 27 and the driving power of the turning mechanism 24, and reduce the center of gravity of the whole machine.

The boom lifting steel wire rope 4 controlled by the boom lifting mechanism 9 enables the double-layer boom unit 18 to realize lifting movement through the boom lifting pulley mechanism 6 arranged on the truss type upright 5 and the guide boom 180201. As shown in fig. 29 and 30, when the dock water level and the ship loading capacity change, the main arm frame assembly 1804 always approaches the ship hatch, so that the lifting height of the vertical buried scraper reclaiming arm 19 on the trolley 20 for extracting materials from the cabin is minimized, the ship unloading efficiency can be improved, and the energy consumption can be reduced.

When the ship is light and idle at high water level, the double-layer arm support unit 18 can be lifted to the highest position, and then the vertical buried scraper blade material taking arm 19 is combined for lifting, so that the vertical buried scraper blade material taking arm 19 can realize unloading so as to facilitate the cabin replacement operation or the ship to drive off the wharf.

The trolley 20 is traction type, has light weight and simple structure, and can reduce the moving load acting on the main arm support 180402.

The material conveyed by the arm support scraper 21 is transferred to the swing embedded scraper 17 through the arm support scraper discharge chute 2102 and the swing embedded scraper feed chute 1701. The material conveyed by the swinging buried scraper conveyor 17 is transferred to the rotary chute 11 through the swinging buried scraper conveyor discharge chute 1703 and the rotary chute feed chute 1101. The material is then discharged to the quay belt 14 via the rotary hopper 1601, the center hopper 1602, and the bifurcated chute 1603. The materials are continuously lifted, transported and switched in the closed space, so that the efficiency is high, the energy consumption is low, and the environmental protection performance is good.

The center hopper 1602 and the forked chute 1603 are fixedly mounted to the gantry 12 by a center chute support 1604. The turning hopper 1601 is connected to the center hopper 1603 and is rotatable about the center of rotation of the machine. When the revolving mechanism 24 drives, the truss type upright 5 drives the double-layer arm support unit 18, the arm support scraper machine 21, the swinging embedded scraper machine 17 and the rotary chute 16 to revolve, and the revolving hopper 1601 can revolve along with the revolving. The center hopper 1603 volume is greatly enlarged to reduce material flow rate and impact of material on the dock belt 14.

When the double-layer arm support unit 18 is lifted, the lower part of the rotary chute 11 rotates around the rotary center of the chute to perform fixed-point rotation; the swing embedded scraper 17 is arranged on the bridge 1702, the front swing embedded scraper feeding chute 1701 is lifted and lowered along with the arm frame scraper 21, and the rear swing embedded scraper discharging chute 1703 is rotated along with the rotary chute 11. The swing embedded scraper 17 adopts an embedded scraper to carry out material conveying, so that the problem of material lifting under a large inclination angle can be solved, and the problem is shown in fig. 29. In order to realize continuous material conveying on the premise of ensuring the relative motion relationship among the arm support scraper conveyor 21, the swing embedded scraper conveyor 17 and the rotary chute 11, the three are mutually rotatable in a switching way. The swinging buried scraper feeding chute 1701 is connected with the cantilever crane scraper discharging chute 2102 and can rotate around the center of the cantilever crane scraper discharging chute; the rotary chute feed chute 1101 is connected to the swing buried scraper conveyor discharge chute 1703 and is rotatable about the swing buried scraper conveyor discharge chute center. As shown in fig. 28, the horizontal directions of the joints of the arm frame scraper 21, the swinging embedded scraper 17 and the rotary chute 11 are adjacently staggered, and the height direction has enough height difference, so that the smooth self-flowing of the materials can be ensured, and the blockage can be avoided.

When the material is large in volume and uneven in particles, the vertical buried scraper material taking arm 19 can be replaced by a chain bucket elevator (shown in fig. 33), the arm frame scraper machine 21 can be replaced by a belt conveyor (shown in fig. 34), and the swing buried scraper machine 17 can also be in a full-spread scraper form (shown in fig. 35).
