Product Description
Detailed Specifications & Features
Open-Window Safe Bottom Chain Inspection | 90-1300kW High-Power Drive | Scraper Conveyor
Designed for coal mining face short-distance material conveying, this scraper conveyor provides reliable transportation and essential support functions for modern mining operations.
Product Overview
The scraper conveyor is specialized mechanical equipment for material transfer, primarily used for short-distance horizontal conveying or at inclination angles up to 15 degrees. Comprising core components including frame, roller, scraper, chain, motor, and reducer, this equipment serves multiple critical functions in coal mining operations. It transports coal cut by the shearer or spalling coal while simultaneously acting as the running track for the shearer and providing a fixed fulcrum for pulling and moving hydraulic supports.

Core Features & Benefits
- High-Strength Multifunctional Middle Section: The middle trough combines cast baffle trough gangs, cast shovel plate trough gangs, middle plates, and bottom sealing plates through casting and welding, securely connected by dumbbell pins. Pin rows are specially installed to serve as the traction track for the shearer.
- Open-Window Structure for Safety and Convenience: An open-window middle trough is configured every ten sections to facilitate bottom chain inspection. The positioning accuracy between window plate and middle plate remains unaffected by trough gang deformation, maximizing structural strength while ensuring the shortest extraction distance for safe and reliable operation.
- Multi-Purpose Cable & Deflection Troughs: The cable trough bolts to the middle trough, preventing coal spillage toward the goaf side while supporting and suspending shearer cables, water pipes, and support emulsion hoses. The deflection trough enables horizontal deflection toward the coal wall, allowing the shearer to cut through upper and lower roadways.
- Versatile Reducers & Forced Chain Stripper: Available in three structural types (fixed shaft gear, planetary gear, and offset drive) covering a robust power range of 90-1300kW. The chain stripper at the head forces the ring chain to safely exit the sprocket at the normal separation point, ensuring smooth operation.
Frequently Asked Questions
Besides transporting coal, what other roles does the scraper conveyor play at the working face?
Its functions are highly comprehensive. In addition to transporting coal, it serves as the running track for the shearer, provides a fixed fulcrum for pulling and moving hydraulic supports, cleans floating coal on the working face, and suspends/supports cables, water pipes, and emulsion pipes.
Can this conveyor be used for steep incline transportation?
It is not suitable for steep inclines. This scraper conveyor is designed for horizontal conveying or short-distance conveying with inclination angles no greater than 15 degrees.
If there is an issue with the bottom chain, is it difficult to inspect and repair?
Not at all. The equipment features an "open-window middle trough" configured every ten sections. This specialized design ensures the shortest possible extraction distance during bottom chain inspection, making maintenance highly convenient while maintaining high structural strength for safe and reliable operation.
