Description

Technical Field

[0001] The utility model relates to the technical field of coal compaction and leveling equipment, and particularly relates to a grading compaction and leveling device for coal in a carriage. Background Art

[0002] During the process of loading coal into a train carriage, the coal in the carriage is uneven and loose. During the train transportation process, the coal in the carriage is very likely to spill, causing unnecessary waste and traffic safety accidents. Therefore, a compaction and leveling device is adopted. By arranging the compaction and leveling device at the subsequent position of the loading process, the coal higher than the upper plane of the carriage can be compacted, pressed tightly and leveled. At present, for the compaction and leveling device, generally a roller with a large volume and weight is used for compaction and leveling. To improve the compaction effect, the weight of the roller may be increased. After compacting one carriage, the roller needs to be lifted by a traction mechanism. After the roller is located above the next carriage, the roller is lowered to continue the compaction operation. Thus, the roller is an integral structure with a large weight, which is not convenient for handling, installation and maintenance. In addition, the roller is an integral structure. For the compaction and leveling operations of carriages of different models, the entire roller needs to be replaced, which is inconvenient to operate, has low efficiency and low safety.
