Description

Technical Field

[0001] The utility model relates to the technical field of material conveying, in particular to an interlocking control device of a swing-bar conveyor and a material hoist. Background Art

[0002] In the production process, a swing-bar conveyor is used to transport particulate materials, and the materials are sent into the silo through the connected material elevator. This material transportation method adopts fully enclosed transportation during the material transportation process, avoiding dust and spillage, which helps to improve the working site environment and ultimately meet the requirements of clean production. However, the disadvantage is that the materials are transported in a closed manner in the equipment, and the operator cannot monitor its operating status. When the material elevator fails or stops operating, the materials will continue to be sent into the material elevator through the swing-bar conveyor, and finally accumulate at the bottom shaft of the material elevator until the materials are full and overflow from the material elevator feed port. This situation not only damages the lower sprocket shaft of the bucket elevator, but also increases the workload of cleaning the material elevator in the later stage, and affects normal production.
