Clear type loading device for coal mining tunneling machine

Abstract

The invention relates to an unblocked loading device, which mainly comprises a loading frame, a conveying groove, a carrier chain, a groove plate, a diverted shaft, a left and a right shovel plate bodies, a left and a right rotor discs, a left and a right shaft brackets, a left and a right drive discs, a left and a right hydraulic drive mechanisms. The loading device is modified from a semi-closed structure to an unblocked structure, the diverted shaft is shifted from an intermediate position to the front end of the conveying groove, the shovel plate bodies, the drive discs, a rotary disc, the conveying groove, the groove plate and the carrier chain are relatively modified, coal is simultaneously conveyed to an intermediate coal conveying groove through the left and the right shovel platebodies and the rotary plate after the coal which is cut by a cutting mechanism enters into the shovel plate bodies, since the coal conveying groove is smooth, the central portion has no obstruct and barrier, the space of the coal conveying groove is doubled, coal which is cut can be smoothly, rapidly and swiftly delivered to a drag conveyor, compared with the original structure, the work efficiency can improve 40%, coal conveying and loading operation are safe and stable, equipment is not easy to be damaged. The unblocked loading device has reasonable design and structure, which is synchronous to dig, shovel coal, unblock and output.

Description

technical field [0001] The invention relates to a smooth loading device of a coal mining roadheader, which belongs to the technical field of design and manufacture of underground mining equipment in coal mines. Background technique [0002] In large and medium-sized coal mining operations, a large number of roadheaders are used. The structure of the roadheader is mainly composed of a loading mechanism, a walking mechanism, a cutting mechanism, and a hydraulic mechanism. The loading mechanism is to load the coal mined by the cutting mechanism. Transported to the conveying equipment, it acts as a link between the past and the future for loading and transshipment. [0003] The loading mechanism of the currently used roadheader is arranged at the lower part of the cutting device, and the cut coal directly enters the loader, and after being guided by the left and right turntables of the shovel body on the loader, it is guided by the redirecting shaft on the coal delivery chute. ...

Problems solved by technology

[0003] The loading mechanism of the currently used roadheader is arranged at the lower part of the cutting device, and the cut coal directly enters the loader, and after being guided by the left and right turntables of the shovel body on the loader, it is guided by the redirecting shaft on the coal delivery chute. Drive the conveyor chain to transport to the external scraper conveyor. The coal delivery chute of the existing loading mechanism is a semi-closed structure. The coal is stored in the 1 / 2 position of the conveying trough, and then the reversing shaft drives the conveying chain to output. Since the reversing shaft is installed in the middle of the conveying trough, the use volume of the conveying trough is significantly reduced, and the use of space is seriously insufficient, making the coal The transportation is greatly restricted, so that the cut coal cannot be exported quickly and in time, and the production efficiency is seriously affected. Even due to the accumulation of coal and poor output, it will cause a backlog of coal, which will cause safety accidents and even damage equipment.
