It is known that the telescopic heavy chain plate conveyor is a new transportation equipment, the construction personnel in the design and construction should be based on scientific methods, correctly understand the conveyor transport principle, baffle design principle, to maintain the normal work of the conveyor. The following is the operation principle of the machine:

First, the operation principle of the telescopic plate conveyor:

The operation principle of telescopic plate conveyor is: the head wheel rotation, so as to drive the guide plate movement on the transport chain. At the bottom of the conveyor, the tail of the CAM after the roller moved to the scraper, scraper contraction, through the stretch of the spring, bag materials use and guide plate friction between the forward. During the material rise, the CAM of the head and the CAM of the tail are separated from the roller, and the scraper pulls the spring to help the material rise. If the material is bone, rice and other scattered aggregate, the scraper should be less out of some, using the bag itself to send out a boost to transport.

Two, the working principle of the telescopic scraper:

In the heavy chain plate conveyor head and tail two parts of the roller driven scraper principle, so that the scraper formed a contraction phenomenon. In the ascending stage of the conveyor, the CAM of the head with the CAM of the tail and the roller are separated, the scraper is stretched out under the action of the spring tension, and the bag of material is placed in front of the scraper, the scraper is compressed. At the end of the nose and tail of the transport plane, the auxiliary plate shrinks, and the scraper extends during the ascending stage of the conveyor, so that the safe transportation of materials can be maintained. In the transport machine, the application of telescopic baffle is to avoid the bag material is stuck by the splint caused by bag damage phenomenon.

In the upward transport stage of the conveyor, if the height of the machine scraper is fixed, it becomes a fixed scraper conveyor. In this way, the material placed on the horizontal plate may be stuck between the two guide plates, and the bag will be damaged due to the friction caused by the operation of the machine, so that the machine cannot operate normally and the material cannot be transported normally. Using the scalability of the scraper, can be placed in the material below the guide plate does not stretch out or less stretch out, so as to avoid the material is stuck by the machine, so that the transport behavior is normal and orderly.

In the head section of the heavy chain conveyor, if the scraper can not shrink in time, the bagged material may touch the baffle plate of the machine in the process of falling, causing damage. In the end of the machine set guide plate shrinkage this link, not only can protect the safety of the material from the source, but also can keep the safety of the stevedores, the best of both worlds.
