Description

Technical Field

[0001] The utility model relates to the technical field of slag shovel sprockets, in particular to a slag shovel sprocket transmission mechanism with an anti-sticking chain. Background Art

[0002] The principle of the drag sprocket device of the slag picker is: under the action of the motor, the driving device engages with the drag chain of the slag picker to drive the slag picker to operate. The drag sprocket device of the slag picker is generally divided into convex tooth type and concave tooth type. In the existing technology, due to the casting defects of the drag sprocket, the matching clearance between it and the chain is not appropriate, resulting in a certain part of the chain cannot be smoothly disengaged when it turns to the bottom, that is, as the sprocket continues to rotate, the sprocket and the chain will produce a stuck phenomenon, causing the stuck part to roll back upwards. This phenomenon is called sprocket sticking. The sticking of the drag sprocket of the slag picker will cause the current or oil pressure of the slag picker to fluctuate. In severe cases, it may cause the slag picker to stop operating due to overload, or even the chain to break, causing the unit to be load-limited for emergency repair. Utility Model Content
