Description

Technical Field

[0001] The utility model belongs to the technical field of residual coal cleaning, and in particular relates to an automatic car cleaning system for a car tipper. Background Art

[0002] Coal is mainly transported by open train carriages, and unloading is usually done by a dumper. Since coal is piled up during transportation, it is inevitable that it will adhere to the walls and bottom of the carriage, so it is necessary to clean the remaining coal. Most of the existing cleaning methods use manual cleaning or automatic high-pressure water gun flushing. However, manual cleaning is not only inefficient and time-consuming, but also has a harsh working environment; automatic high-pressure water gun flushing uses more water, causing serious on-site pollution, and makes the loose coal contain more water, which causes inconvenience for subsequent turnover. At the same time, high-pressure water gun flushing cannot remove the harder loose coal that is hardened or frozen in the carriage; Patent CN 216272101U discloses a dumper open car carriage residual coal cleaning device, which uses a hydraulic cleaning and shoveling coal structure to clean the residual coal more forcefully and quickly, and can clean and flush the carriage with gas or liquid, but the design of the second cavity, radial air duct, and longitudinal air duct in the patent is unreasonable, resulting in too much kinetic energy loss of the gas or liquid sent by the air supply pipe, affecting the cleaning or flushing effect.
