There are many types of scraper conveyor for mining, and the form and layout of each component are also different, but its main structure and basic components are the same, which is composed of four parts: head, body, tail and auxiliary equipment.

The machine head is the transmission device of the conveyor, including the head frame, motor, hydraulic coupling, reducer, head spindle and sprocket components. Scraper conveyor for mining The function of the motor is to drive the scraper to run in the chute through the coupling, reducer, head spindle and guide sprocket to transport coal out.

The fuselage is the coal conveying part of the conveyor, which is composed of the trough body and scraper chain. The trough body is the main body of the conveyor body, which is the supporting and guiding component of the load and scraper chain. It is welded and pressed by steel plate and is divided into middle groove, regulating groove and connecting groove. Scraper chain is composed of chain link and scraper.

The tail part is composed of tail frame, tail shaft, chain tightening device, guide chain wheel or tail roller; guide sprocket is used to change the direction of scraper chain; chain tightening device is used to adjust the tightness of scraper chain.

Auxiliary devices include chain tightening device, chute hydraulic jack and anti-skid device.

When the scraper conveyor is working, the open trough body is used as the bearing part of coal, gangue or material, and the scraper is fixed on the chain (forming scraper chain) as traction component. When the head drive part is started, the chain wheel on the head shaft of the belt conveyor rotates to make the scraper chain run circularly, and the animal material moves along the tank until it is unloaded at the head of the machine. The scraper chain bypasses the chain wheel and operates in stepless closed cycle to complete the conveying of materials.

Scraper conveyor can be used for horizontal transportation and inclined transportation. When the coal seam is transported upward along the incline, the inclination angle of the coal seam shall not exceed 25 ° and that of the downward transportation shall not exceed 20 ° and the anti-skid device shall be installed when the coal seam dip angle is large. Flexible scraper conveyor is allowed to bend 2 ° to 4 ° in horizontal and vertical direction.
