Scraper conveyor Compared with the convex sprocket, the movable chain wheel with concave tooth structure is more adaptable to the domestic circular chain, which can ensure that the chain will not wear after serious wear and circumference wear. Increase. Thus, the chain replacement cycle is greatly prolonged.
The corresponding chain tension adjustment adopts worm gear deceleration self-locking tensioning mechanism, which saves labor and is easy to operate, and ensures that both sides are tensioned at the same time. At the same time, the high-strength mining circular chain of scraper conveyor is used as the conveying chain, which has greater bearing capacity and wear resistance. Due to the characteristics of material transfer, the reflux chain and scraper are separated from the material, thus avoiding the sudden increase of feed volume. Increased and blocked the doctor blade accidents caused by engine room.
The model and specification of scraper conveyor are determined according to the large throughput required by the process. After the selected scraper conveyor is selected, whether it is horizontal or vertical in the working process. When the material enters the closed machine slot from the feed port, the loose material will form enough internal friction under the action of scraper thrust and material gravity.
Advantages of scraper conveyor:
1. The structure is solid. It can withstand the impact, impact, impact and pressure of coal, gangue or other materials.
2. It can adapt to the needs of uneven floor and bending in coal mining face, and can bear vertical or horizontal bending.
3. Low fuselage, easy to install.
4. It can be operated in reverse direction, which is convenient for handling bottom chain accidents.
5. It can be used as the fulcrum of the front section of the hydraulic support.
6. The structure is simple and can be fed or unloaded at any point in the conveying length.
In case of the following situations, stop the vehicle immediately.
1. The chain is broken or there are too many residual chains at the lower end of the head sprocket
2. The scraper is seriously deformed, the chain of the machine head falls off, and the screw of the connecting ring is broken
3. The chute is damaged and arched, and the chute is bent excessively, resulting in disconnection or chain out of the chute
4. The main connecting screws of the head are loose or the gearbox of the head motor vibrates violently
5. Overheat or abnormal noise of motor, reducer, tile box, bearing, etc
6. Strictly implement the post responsibility system and system and other safety precautions.
