[0001] The utility model relates to the technical field of mineral transport equipment, in particular to a grab bucket device for coal. Background Art

[0002] Coal is an energy mineral, and its derivative products involve many important fields. It is an important energy material. Most of the coal mined from the mining area will be temporarily piled in an open space and then transferred and transported by mechanical equipment. Grab bucket equipment is needed here. It can grab a large amount of coal at a time and move the coal to another location for unloading. It is a modern and efficient coal transfer and transportation operation equipment that can greatly improve the operation efficiency of the mining area.

[0003] Most of the existing coal grabs have open tops, which easily allow a large amount of coal dust to escape from the surrounding areas and top of the grab, causing air pollution and endangering the health and safety of workers.

The moving seat 2 is driven by the hydraulic cylinder 3 to achieve lifting and moving. The bottom surface of the opening and closing mouth of the bucket body 5 and the edges of the side surface are fixedly welded with shovel plates 6.

[0022] Top sealing plates 7 are fixedly welded on the tops of the left and right ends of the bucket body 5, which can greatly reduce the dust escaping from the top when grabbing coal mines. The ends of the two top sealing plates 7 that are close to each other maintain a distance from the lower support beam 4 to prevent interference when the bucket body 5 is opened. Two ear plates 8 are fixedly welded on the two ends of the outer surfaces of the two top sealing plates 7 in opposite directions.

[0023] There are through openings on both ends of the bottom of the movable seat 2. The front and rear ends of the left and right ends of the movable seat 2 are movably installed with support rods 9 through the through openings. The bottom end of the support rod 9 is movably connected to the bucket body 5 through the ear plate 8. During the lifting and lowering process of the movable seat 2, the opening and closing of the bucket body 5 is driven by the support rod 9.

[0024] There are two water tanks 10, which are respectively located in the middle of the outer top surface of the two top sealing plates 7. The outside of the water tank 10 is evenly spaced with a fixing frame 11. The top of the fixing frame 11 is fixedly connected to the water tank 10 by bolts, and the bottom of the fixing frame 11 is fixedly connected to the top sealing plate 7 by bolts, which can store water for dust-proof spray.

[0025] Two submersible pumps are provided inside the water tank 10, and the two submersible pumps are respectively located at the front and rear ends of the water tank 10.
