Description

Technical Field

[0001] The utility model relates to a conveyor belt cleaning device which can avoid further damage to a damaged conveyor belt, belonging to the technical field of ship unloader conveyor belt equipment. Background Art

[0002] In the process of port production, in order to enable the boom of the ship unloader in the dry bulk cargo terminal to adapt to various ship types, many booms of ship unloaders are designed in a telescopic form. Compared with a fixed boom, a telescopic boom requires more redirecting rollers. Therefore, within the same operating time, the number of bends of the conveyor belt of the telescopic boom is much more than that of the conveyor belt of an ordinary fixed boom, resulting in a shorter service life of its joints and frequent breakage of the joints. Once the conveyor belt is damaged, it is extremely easy for the damaged position to rapidly expand when passing through P-type and H-type cleaners, causing serious damage to the conveyor belt. In actual production, a cleaning device must be configured to solve the problem of coal on the return conveyor belt in order to meet environmental protection requirements. Therefore, it is very necessary to design a cleaning device that can not only achieve the cleaning effect but also not easily cause further damage to the damaged position of the conveyor belt. Content of the Utility Model

This cleaning device can continue to perform the cleaning operation when the conveyor belt is damaged, without increasing the further damage to the damaged part of the conveyor belt. While maintaining the cleaning operation, it reduces the damage to the conveyor belt to wait for the repair of the maintenance personnel and reduces the production cost.

[0004] The technical solution to solve the above technical problem is as follows:
