The chain scraper conveyor is an important equipment for the collection and transportation of finished materials. It consists of 9 7.5-meter chain paths, 3 drive shafts equipped with sprocket wheels and a drive motor reducer. The chain bypasses the sprocket on the drive shaft and the head and tail sprocket on the chain path to form a closed ring. With the help of the traction and load of the chain, the steel is continuously conveyed. The drive of the chain is completed by the transmission device, and the motor is started by the reducer. The power is transmitted to the main shaft equipped with sprocket, and the chain is driven by the sprocket to achieve the purpose of conveying steel. Due to the increased production rhythm, the chain scraper conveyor is often overloaded or blocked in conveying, which increases the running resistance and the motor runs overloaded. In order to meet the requirement of no oil stains on the finished material, the transmission bearing cannot be lubricated in time after long-term use, which also leads to the increase of motor power and the phenomenon of motor burnout and tooth punching.
At present, the main drive sprocket of the scraper chain conveyor is integrated. It is hot-mounted on the drive shaft and fixed by a positioning pin. During the movement with greater impact, the relative movement of the sprocket and the drive shaft often occurs, causing the chain Wear of wheels and drive shafts. Inconsistent movement of the 9 groups of chains affects transportation. Due to the dramatic increase in the production rhythm, the failure rate of the mechanism also increased sharply. Later, the sprocket and the drive shaft had to be firmly welded together, so that the equipment that could be dismantled and replaced became one-time use. Secondly, the sprocket of the chain scraper conveyor is constantly worn out during long-term use, and the gear is prone to wear, causing the sprocket and the chain to be unsteady. If you want to change the sprocket, you need to remove the drive shaft as a whole. It takes a long time and the labor intensity of workers is high.
