[0002] In the prior art, when unloading granular materials (such as ore, corn, etc.), a grab bucket is generally used for grabbing and unloading. The grab bucket is very large. As the grab bucket grabs, the height of the material in the cabin gradually decreases. When only shallow materials are left in the cabin, a forklift is generally hoisted into the cabin, and the shallow materials are pushed together, and then grabbed by the grab bucket.

[0003] In the above method, the material needs to be accumulated to a certain volume before it can be grabbed by a grab bucket, and as the material gradually decreases, other methods are still needed to unload the shallow material, which is not convenient enough. Utility Model Content

[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] See also Figure 1 to Figure 4 In an embodiment of the utility model, a port automatic ship unloading device includes a conveying mechanism for conveying the shallow material remaining at the bottom of the cabin, and the conveying mechanism includes a loading unit and a transmission unit;

[0028] The loading unit is connected to one end of the transmission unit and is used to grab the shallow materials at the bottom of the cabin;

[0029] The transmission unit is used to transport the materials grabbed by the feeding unit outwards;

[0030] The loading unit is arranged in an inclined state, the high point of the loading unit is inclined toward one side of the transmission unit, and the low point of the loading unit is inclined toward the side away from the transmission unit.

[0031] In this embodiment: after using the grab bucket to transport most of the materials in the cabin to the outside, the shallow materials remaining at the bottom of the cabin are transported by this device;

[0032] Transport the device to the bottom of the cabin and start the loading unit. The running loading unit scoops up the shallow material and transports it to the conveying unit. The conveying unit transports the material to the outside. The material gradually becomes shallower. When the top surface of the material is lower than the lowest point of the loading unit, the material is pushed to the loading unit by manual operation equipment (such as a push plate or a shovel truck). The material accumulates at the loading unit. At this time, the device can continue to transport the material in the cabin to the outside.

[0033] Please refer to Figure 1The transmission unit includes an "L"-shaped hoist 1, a No. 1 motor 2 is installed on the outer shell of the hoist 1, and the No. 1 motor 2 drives a synchronous belt 3 through two synchronous wheels, and the two synchronous wheels are rotatably installed at both ends of the inner side of the outer shell of the hoist 1;

[0034] The outer wall of the synchronous belt 3 is formed with ribs 4 protruding outwards;

[0035] A rotating pressure plate 5 for limiting the bending position of the synchronous belt 3 is rotatably connected to the inner side of the outer shell of the elevator 1 , and the spacing between the two groups of rotating pressure plates 5 is equal to the length of the rib 4 .

[0036] In this embodiment: after the loading unit transports the material to a high place, the shovel bucket 11 is tilted and opened downward, and the material in the shovel bucket 11 falls on the synchronous belt 3 of the elevator 1. The transmission direction of the synchronous belt 3 is: from a low place to a high place, and then from a high place to a low place. The synchronous belt 3 drives the material falling thereon to be transmitted outward. During the transmission process, the ribs 4 play a role in supporting the material, preventing the material from freely sliding down in the process of moving upward with the synchronous belt 3;

[0037] The rib 4 can be designed as a straight structure or a V-shaped structure. On the surface of the conveyor belt that is transmitted from bottom to top, the opening of the V-shaped rib 4 faces the upward transmission direction.

[0038] Please refer to Figure 1 and Figure 2 The feeding unit includes a chain conveyor 9 mounted on one end of the elevator 1 through a mounting frame 8, a second motor 12 is mounted on one end of the outer shell of the chain conveyor 9, and the second motor 12 drives the transmission plate 10 through a sprocket and a chain;

[0039] The chain is arranged along a track formed by a plurality of transmission plates 10 and is fixedly connected to the inner side of the transmission plates 10. Two sprocket wheels are rotatably connected to the inner sides of both ends of the outer shell of the chain conveyor 9. The sprocket wheels mesh with the chain. One sprocket wheel is connected to the output end of the second motor 12.

[0040] Two adjacent transmission plates 10 are respectively fixed to the outer wall of the outer link plate and the inner link plate of the chain.

[0041] In this embodiment: the second motor 12 drives a sprocket to rotate, and one sprocket drives another sprocket to rotate through a chain, and the outer chain plate and the inner chain plate of the chain are connected to multiple transmission plates 10, so the transmission plate 10 is transmitted.

[0042] Please refer to Figure 3 and Figure 4A connecting groove 14 is provided on one side of the transmission plate 10, and a rotating seat 13 is integrally formed on the other side of the transmission plate 10. Two adjacent transmission plates 10 are rotatably connected with the rotating shaft through the rotating seat 13 and the connecting groove 14. The rotating shaft is formed at two ends of the rotating seat 13, and the rotating shaft passes through the interior of the transmission plate 10. A shovel bucket 11 is provided on the outside of the transmission plate 10.

[0043] In this embodiment, when the plurality of transmission plates 10 are being driven along the chain, the adjacent transmission plates 10 are relatively rotated through the rotating seats 13 and the connecting grooves 14 .

[0044] Please refer to Figure 4 A connecting ear 15 protruding outward is formed at the outer side of the shovel bucket 11 near the transmission plate 10, and two fixing ears 16 are rotatably connected to both ends of the connecting ear 15.

[0045] In this embodiment, since there are two rotation connection points between the shovel bucket 11 and a transmission plate 10 , the transmission plate 10 and the transmission plate 10 connected thereto remain in a relatively static state.

[0046] Please refer to the figure in particular, one end of the shovel bucket 11 is in an open state.

[0047] In this embodiment: during the transmission process of the shovel bucket 11 from top to bottom, the opening of the shovel bucket 11 is downward, and the remaining materials on the bottom layer of the cabin can be shoveled. When it moves to the low point and then moves upward, the opening of the shovel bucket 11 changes from downward to upward, thereby carrying the materials from the low point to the high point. When the shovel bucket 11 moves to the highest point, it will move from the high point to the low point. At this time, the opening of the shovel bucket 11 changes from upward to downward, and the materials fall on the elevator 1 under gravity.

[0048] Please refer to Figure 1 and Figure 2 A vertically fixed support frame 6 is installed on the outer wall of the outer shell of the hoist 1, and a bottom plate 7 is installed on the bottom end of the support frame 6.

[0049] In this embodiment, before the bottom plate 7 is placed on the bottom of the cabin, the materials at the placement position are first cleaned to achieve contact between the bottom plate 7 and the bottom of the cabin, thereby achieving stable placement of the device.

[0050] What is described above is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
