SGB620/80 Portable Coal Belt Conveyors Machine

Advantages of scraper conveyors

1. Solid structure. It can withstand the impact, impact, smashing, pressing and other external forces of coal, gangue or other materials.

2. It can adapt to the needs of uneven bottom plate and bending movement of coal mining face, and can withstand vertical or horizontal bending.

3. The body is short and easy to install.

4. It can also be used as a track for shearer operation.

5. It can run in reverse, which is convenient to deal with the bottom chain accident.

6. It can be used as the fulcrum of the front section of the hydraulic support.

7. The structure is simple, and the material can be fed or discharged at any point along the conveying length.

8. The casing is airtight, which can prevent dust from flying and polluting the environment when conveying materials.

9. When there is no casing at the tail, and the scraper is inserted into the material pile, the material can be reclaimed and conveyed by itself.

The conveyor that is pulled by the scraper chain and transports the bulk material in the tank is called the scraper conveyor. KS scraper conveyor The adjacent middle grooves of the scraper conveyor can be bent to a limited extent in the horizontal and vertical planes, which are called flexible scraper conveyors. The working face conveyor with the fuselage bent at 90 degrees at the intersection of the working face and the transport roadway is called "corner scraper conveyor". In the current coal mining face, the function of the scraper conveyor is not only to transport coal and materials, but also the running track of the shearer, so it has become an indispensable main equipment in the modern coal mining process. The scraper conveyor can keep running continuously, and the production can be carried out normally. Otherwise, the entire coal mining face will be in a state of shutdown, causing the entire production to be interrupted.

The main structure and components of various types of scraper conveyors are basically the same. It consists of three parts: the nose, the middle and the tail.

In addition, there are accessories such as hydraulic jacks for push conveyors and chain tensioners for chain tensioning. The head of the machine is composed of a head frame, a motor, a hydraulic coupler, a reducer and a sprocket. The middle part is composed of transition groove, middle groove, chain and scraper. The tail of the machine is a device for the return of the scraper chain. The tail of the heavy-duty scraper conveyor is also equipped with a power transmission device like the head, which is called the upper head and the lower head according to the installation position.

According to the arrangement and structure of the chute of the scraper conveyor, it can be divided into two types: parallel type and overlapping type. According to the number and arrangement of chains, it can be divided into four types: single chain, bilateral chain, double center chain and triple chain.
