Problems solved by technology

However, directly using the lower belt of the belt conveyor to transport the gangue has problems such as the back of the belt is not wear-resistant and the gangue is easy to roll off on the lower belt of the belt conveyor, which limits the operation method of using the lower belt of the belt conveyor to transport the gangue. use

Embodiment Construction

[0025] The present invention will be further described below in conjunction with embodiment and accompanying drawing.

[0026] Such as figure 1 , figure 2 and image 3 As shown, the belt conveyor for two-way transportation of coal and gangue in this embodiment is equipped with a covering belt 2 for the lower belt conveying materials above the lower belt of the ordinary belt conveyor 1. The lower belt of the belt conveyor 1 contacts and runs with it under its drive. When there is no gangue load, the covering belt 2 and the lower belt are in a parallel separation state and stand still. Both ends of the cover belt 2 enter and exit the cover belt working position through a set of cover belt non-vertical entry and exit redirection rollers 6, and then return to the non-working position through a set of cover belt vertical redirection rollers 7. The gangue to be transported is loaded into the cover belt 2 by the gangue feeding device 3 located above the front end of the cover bel...

Abstract

The invention discloses a bidirectional belt conveyor for coal and gangue. The bidirectional belt conveyor is characterized in that a passive covering belt is arranged above a lower belt of a common belt conveyor, and two ends of the covering belt access a working position of the covering belt via non-perpendicular access bend rollers of the covering belt and then return a non-working position via vertical bend rollers of the covering belt in an access circulation manner; a gangue feeding device and a plow discharger are respectively arranged at the front end and the rear end of the working position and correspond to the covering belt; the covering belt is provided with a tensioning roller; cushion carrier rollers are arranged on the common belt conveyor and correspond to the gangue feeding device, and trough type carrier rollers are arranged on the common belt conveyor and correspond to sections of the covering belt. Original facilities and original power of the existing common belt conveyor are sufficiently utilized by the bidirectional belt conveyor to convey the raw coal and the gangue in two directions. The bidirectional belt conveyor has the advantages that the bidirectional belt conveyor is low in working energy consumption; the covering belt is simple in structure; the belt is not in direct contact with the gangue, and accordingly the service life of the belt is unaffected; the gangue cannot roll easily; the covering belt can be automatically separated from the lower belt when the gangue is not conveyed by the bidirectional belt conveyor, and original functions of the common belt conveyor are unaffected.

Description

technical field [0001] The invention relates to a coal mine belt conveyor, in particular to a coal gangue two-way conveyor belt conveyor. Background technique [0002] Coal mine belt conveyor is a continuous coal mine transportation machine, usually used for one-way transportation of coal, and for special operations, the upper and lower belts of the belt conveyor are used for two-way transportation. The latter generally has three situations: one is to use the lower belt of the ordinary belt conveyor to temporarily transport materials under the guidance of the operating rules; Third, in the comprehensive mechanized coal mining operation, the telescopic belt conveyor is used to change the hanger into a two-way hanger, the upper belt transports raw coal, and the lower belt transports long materials or tools. In addition, there is another situation, that is, according to the needs of some coal mining sites, the lower belt of the belt conveyor is used to transport gangue to the ...
