Description

Technical Field

[0001] The utility model relates to the technical field of excess coal recovery for coal-loading vehicles, and in particular to an excess coal recovery device for coal-loading vehicles. Background Art

[0002] Coal is a combustible black or brown-black sedimentary rock. Coal usually occurs in rock strata or veins in coal beds or coal seams. During the transportation of coal, special coke oven coal-loading cars are required to transport the coal. During the transportation of coal, the coal will adhere to the inner wall of the coal-loading car, which is not convenient for the recovery and utilization of the remaining coal, affecting the transportation of coal.

[0003] In the prior art, the utility model with authorization announcement number: CN217705918U is named: a residual coal recovery device for a coke oven coal loading car. The device proposed in the patent document, through the structural design of the impact mechanism, after the coal in the main body of the coal loading car is unloaded, a small amount of residual coal is attached to the inner wall of the main body of the coal loading car, and the residual coal needs to be cleaned up, and the lifting plate is pressed downward, and the lifting plate drives the two connecting rods to move. The connecting rod drives the two moving plates to move to both sides, and the moving plate drives the impact block to move, and the lifting plate is suddenly released. Under the action of the spring, the impact block will suddenly hit the side wall of the main body of the coal loading car, and the impact will generate vibration. The vibration can make the attached residual coal fall off, realizing the function of cleaning the residual coal attached to the inner wall of the main body of the coal loading car, solving the problem that the inner wall of the current coal loading car is attached with residual coal that is inconvenient to remove, and improving the cleaning efficiency of the residual coal;

[0004] However, when the device is used to transport coal, workers are required to open the door and use tools to take out the coal. After taking it out, the remaining coal attached to the wall of the vehicle is shaken off by the device components, and then the coal is taken out. Therefore, it is troublesome for the workers. Although the remaining coal can be removed, it is time-consuming and labor-intensive to use.

[0005] In the prior art, the utility model with the authorization announcement number CN216688006U is named: A residual coal recovery device for a coke oven coal loading car. The device proposed in the patent document can make the coal loading car body have the function of lighting by arranging a placement box and a protection plate on the coal loading car body, so as to facilitate the transportation of coal in dark places. The angle of the lighting lamp can be adjusted by arranging a connection block, a connection groove, a movable rod, a limit hole and a limit bolt.

[0006] However, when transporting coal, some residual coal will adhere to the inner wall of the vehicle. Although the device can facilitate transportation in dimly lit places, the residual coal attached to the inner wall of the vehicle cannot be removed, making it inconvenient to clean and recycle the residual coal. Therefore, the staff needs to use tools to clean the residual coal, which is time-consuming and labor-intensive. Utility Model Content
