Brief Introduction:
The main structure and components of various types of scraper conveyors are basically the same. It consists of three parts: head, middle part and tail part.
In addition, there are auxiliary parts such as hydraulic jack device for pushing conveyor and chain tensioner for chain tightening. The head part is composed of head frame, motor, hydraulic coupler, reducer and sprocket. The middle part is composed of transition groove, middle groove, chain and scraper. The tail part is a device for the return of the scraper chain. The tail of the heavy scraper conveyor is also equipped with a power transmission device, which is called the upper head and the lower head from the installation position.
Classification:
According to the layout and structure of the scraper conveyor chute, it can be divided into two types: parallel type and overlapping type. According to the number and layout of chains, it can be divided into four types: single chain, double chain, double center chain and three chain.
Practical Application:
The scraper conveyor can be used for horizontal transportation or inclined transportation. The inclination angle of the coal seam shall not exceed 25 ° for upward transportation and 20 ° for downward transportation. When the inclination angle of the coal seam is large, anti-skid devices shall be installed. The bendable scraper conveyor allows 2 ° - 4 ° bending in the horizontal and vertical directions.
