Profile

Extensible belt conveyor is a kind of conveyor that it can adjust the length of itself as the changing of working position. Equipped with belt storage device, the body length of the extensible belt conveyor can gradually extend or gradually shorten in line with the requirement of working condition. The max.elongation should not exceed the allowable length of the rated power of the electric motor. The mini. elongation of the extensible belt conveyor can be shortened till the body of the extensible belt conveyor can not be shortened anymore.

As a kind a continuous transportation equipment, belt conveyor is used to convey a large number of bulk freight, such as mineral, coal, sand and other powder, spot adjunct and well-packed freight in metallurgy, mining, power, construction material and other heavy industries and transportation department. Belt conveyor is the most ideal efficient and continuous transportation equipment. Comparing with other transportation equipment, its advantage includes both long distance, large volume, continuous transportation and reliable operation which realizes automation and centralization control. Especially, it is a core equipment for high yield high efficiency in mine and electromechanical integration technology and equipment. Particularly, in recent 10 years, appearing of long-distance, large-volume and high-speed belt conveyor, it is generalized in transportation system on the surface of mine construction, outdoor stope and dressing plant.

Mainly, the extensible belt conveyor is used in roadway conveying in comprehensive mechanized coal mining as well as it can be used in roadway conveying and roadway construction conveying in coal mining operation. When it is used in roadway conveying, the reversed loader equipped on the drive end unit of the extensible belt conveyor is connected with face belt conveyor. When it is used in roadway construction conveying, the adhesive belt reversed loader is connected with head machine on the tail of the extensible belt conveyor.

The structural group and working principle:

The extensible belt conveyor is mainly made up of transmission device on the head piece of extensible belt conveyor, the belt storage device, tensioning gear, elongation and retracting conveying belt device body, drive end unit of the extensible belt conveyor and etc. The non-permanent parts of the extensible belt conveyor include body of the extensible belt conveyor and drive end unit. The left parts are permanent. The body of the extensible belt conveyor is the extensible part.

Conveyor belt is the bearing carrier of the extensible belt conveyor. The material on the belt can be conveyed along with belt conveyor. The material can be unloaded at the front end or in the middle of the extensible belt conveyor in according to the need. The belt conveyor is supported by the spinning carrier belt with small running resistance. The transmission cylinder is drove by  driving device when it works. By meas of the friction between the transmission cylinder and belt conveyor, the belt runs while the materials on the belt will be moved.

The driving device is made up of electric motor, reduction gears, elastic coupling, hydraulic clutch, the connecting cylinder, the drive frame and other parts. In according to the elastic coupling, hydraulic clutch, the torque output of electric motor is delivered to I shaft if reduction gear. And then, the torque is delivered to the transmission shaft of the main drive cylinder of extensible belt conveyor by the triple reduction gear of the reduction gear. The friction drive of cylinder makes the belt circulation movement.

Characteristic feature

In line with the belt storage device of the extensible belt conveyor, it can deploy and contract the body of the machine. Thus, it can enhance the capability of roadway conveyor effectively. Also, it can accelerate the rate of progress of extraction and the tunneling.

The non-permanent of the extensible belt conveyor is connected without bolt fastening, which can detach the stand quickly. It has the following advantage, such as simple structure, convenient detachable, low labour strength and short operation time.

The equipped adhesive tape tensioning device of part body of the machine adopts electric winch to drag tensioning, which has a large stroke of tension

FAQ:

Whether if the delivery value of the same width of belt of extensible belt conveyor can be adjusted?

Of course. The same width of belt of extensible belt conveyor can adjust its delivery value by means of adjusting the speed of the belt to realize.

What is the adhesive tape belt is made of ?

The steel cord adhesive belt, polyester-core adhesive belt, nylon-core adhesive belt and cotton duck fabric rubber belt can be chose in accordance with various working place and environment.

Whether if the sealing-type conveyor can convoy the high temperature material?

Certainly. The resistant to elevated temperature adhesive belt can be used to convey the high-temperature material.

Whether if it is convenient to maintain? What about the maintaining?

It is convenient to maintain with a high degree of modularization. Also, our company provides the 24-hours all weather service new standard, which has the service ability of five stars timely.

Whether if the equipment can be operated continuously?

Of course. Our design for the extensible can realize 24-hours continuous running.

Why the machine is named as extensible belt conveyor?whether is the length of the belt can be changed?

Yes. The belt of the extensible belt conveyor can be elongated and contracted in line with actual condition on spot.
